Battery Life on a SmartPhone - The Riddle, The Enigma
Attaining 20+ hours of battery life is not only possible it is totally attainable with most phone configurations. The secret to making this happen is, understanding what are the contributing factors are and knowing what to do first.
This guide will help. After reading this guide, you will be able to understand how to end power eating culprits and answer those same questions we see over and over in the threads...... that is .... solving the passive battery drain and get the 20 hours of battery life we all want and desire.
I have tried to get almost everything I can think of and put it in one place. We have all seen the threads that say, “Please help with my battery issue”, “Does undervolting save you battery life” or “Getting horrible battery life” (and yes I did use the…SEARCH Button…and these are titles directly from the Q & A section).
Post 1: Tips and Tricks
Post 2: Roms/Kernels, OverClocking/Undervolting and Memory Management
Post 3: Apps (for your download pleasure)
I will be using satirical stories and anecdotes to get my point across below. Not meant to offend or point fingers at anyone. I am just using real life references to get to the point. Also I am not much for fancy colors. I tried it at the top here but not so much further down. If there is something specific I want to call attention too, I will BOLD it and maybe RED it too.
This is not a GUIDE to get better battery life but rather a GUIDEline to get it. What is the difference, you say? A Guide is a step by step process that you must/should follow to get the outcome that the person who created it wanted you to get [A+B+C+D should = E]. A Guideline is more of a recommendation that allows some choice or flexibility in the understanding, execution or use [A +B-(C+D) can = E].
As we all know, all Vibrants are not created equal and so if something works for one person and not the other, then is it a software, hardware or human error. Chances are it is a combination of all three. Hopefully this can slim those down a bit and answer some questions that you might have or have seen.
**Special thanks to NOOB_IN_N33D for his help in gathering info, especially the MIUI/CM7 parts below. Do yourself a favor and hit up his Guide- Easily Flash MIUI for Vibrant. It has themes, modems, kernels,… and he really put a lot of time and effort into it. It is stickied in the QA section so it shouldn’t be too hard to find. Hit his thanks button please.**
TopShelf10 has this to say about getting the most out of your battery life
the problem is, people want to believe that they can save battery without changing their usage habits. this simply is not possible. no rom or kernel will realistically do this for you. if you remove 1 brick from a bag full of 15 bricks, the bag will be lighter, but still very heavy. you need to download "spare parts" or "process monitor" from the market and start analyzing the way your apps are acting. also look into data syncs that are happening in the background. apps that stay open behind your back/what they are doing 9an app called "autostarts" can prevent apps from self-running under certain scenarios). animation speed. polling for notifications. gps. wifi scans. overclocking. cpu/ram usage. proper sleep. widgets. brightness. 2g/3g. data usage. call time. text volume. - THESE are the things that really affect your battery life.
bottom line is, if you truly want to save battery you are going to have to get your hands dirty...there simply isnt a one-click (or one-flash) solution.

Below is a list of fundamental things that can be done without rooting or custom ROM/Kernels. (Standard disclaimer applies: You use it, you set it and you are responsible)
1. Be Realistic -
Do you really think that you can get two whole days out of your battery? If you do, then you must have a very important pile of papers it is sitting on to not even pick up your phone for that long. These are phones. These are mini-computers. These are arcade games. And they want, dare I say, need to be played with, talked on or downloaded to. USE YOUR PHONE.
2. Syncing –
I know you are very important and you need to know what LeBron is doing right now, just in case you get a cup for a coffee and he might be in Starbucks at the same time and you get your picture taken with him and upload it to Facebook, Twitter or Google+. That is fine and I applaud you for it and will probably download the picture and Photoshop myself in your place. This is not the problem. Syncing your accounts is. That is what is causing battery drain. Do you really need to have your FB widget (see widgets section) streaming all day long? Does Kim K.’s endorsement of a potato chip really affect your everyday life? I doubt it. Kill them (not LeBron or Kim K. but rather the auto-syncing). Every time you “friend” someone their numbers, contact info gets sync’d to your phone. Also, there are settings in Facebook, Twitter and Google+ that you can upload pictures instantly. Don’t do that. Once you do, it is out in the Ether-World and just swallowed a bunch of battery doing it too.
Settings>Accounts and Sync>Auto-sync>uncheck it
3. Widgets –
They look cool. But widgets are nothing more than RAM and battery hungry monsters that you purposely put in your home screen. Think about it. What does a widget really do? All it really does is monitor an app that you have running. So not only is it running and taking up battery and RAM but the app that it is linked to is running in the background al’ a Facebook, Twitter, Google+, CNBC, MSNBC, BBC,… the list goes on and on because they want us to put THEM on our home page. What a great marketing campaign the widget is. “Hey look at me new home screen” “Cool. Hey what widget is that?” “Oh, it is X” “Nice, I’ll have to download that tonight when I get home” and then and there they have you and your battery.
4. Apps –
You have to pay attention to your apps. I repeat. You have to pay attention to your apps. Especially if they run in the background. This can be anything from a harmless .99c game to a monster like Live Wallpaper. The battery drain threat is twofold here because the app is running in the background but it could also be using its anonymous data collection abilities and sending that back to the Mothership. Ever wonder why you have a H with up and down arrows in your status bar when your phone is just sitting there? This is because some app is transmitting data, whether you are using it or not. There are apps in the market that monitor these situations like Watchdog or kill the data link when the lock screen is enabled like Juice Defender (see Apps below) or you can adjust app permissions like LBE Privacy Guard. Data transfer is #2 on the What Kills My Battery list.
5. Display/ Wifi/ Airplane Mode/ Animations –
Display:
#1 when it comes to what is eating your battery. Always has been and always will be. Accept it and try to do something about it. This part is easy. Just lower the brightness. You can use Auto or set it as a brightness that is low but you are still able to see well enough to function. Live Wallpapers fall into this category. They are cool to look at but static ones take up less RAM and also less display because they are not running all the time in the background. These screens are bright at 100%, so tone it down. (see Apps below).
WIFI:
Another helpful tip is setting your WIFI sleep policy to Never. This can be done by going here Setting>Wireless>WIFI> Menu key>Advanced>WIFI Sleep Policy and set it to Never.
Airplane Mode Toggle:
NOOB_IN_N33D found this helpful trick too. Phazeman...
"Toggle the airplane mode on/off 3 times in a row, that will reduce your Cell Standby battery usage.
It should only be necessary to do it once after flashing but if you think Cell Standby uses too much power at some stage you could toggle again the airplane mode"…Phazeman
Animations: Set Settings > Display > Animations to "Off or Med. animations.
These are 5 fundamental things that you can do to help reduce battery drain and get some more life out of your phone. Anyone can do these. All you have to do is watch your phone and use some common sense. “Why does my battery drain after only 6 hours? All I was doing was checking Facebook.” Do you really need to be on Facebook for that long of a time? I doubt it. How many services do you have running? How many tasks do you have running? (Android does a good job of shutting down tasks on its own, but if you are using a task killer, it takes more juice to start up an app than to turn it back on, so to say.) Think of it like an airplane. Takes more fuel to get up in the clouds, but once you are up there, it is pretty much coasting along with way less burn.

ROMs/Kernels, Overclocking/Undervolting and Memory Management
ROMs are key things to think about when it comes to battery life. They can be fully established and working fine, can be RCs and still in development or they can be Alpha/Betas and completely experimental or just beginning. Choosing the best ROM or Kernel is going to depend on what YOU want out of your phone. Do you want a stable 2.2 ROM that has great battery life but not the customizability as MIUI or CM7? Do you want a Gingerbread AOSP ROM that has memory leak issues? There is the rub because CM7 and MIUI have fantastic customization possibilities Gingerbread is well Gingerbread but it has its own issues, and 2.2’s are about as basic as they come. However 2.2’s, because they are so old and overworked, have been Optimized to their fullest and some outstanding tweaks have really brought them to the forefront in daily drivers. Again, the choice is up to you.
Kernels go hand-in-hand with your ROM. Does the kernel support Overclocking or Undervolting. How much RAM and what tweaks are included in the kernel? Does THIS kernel work with THAT ROM? These are all spelled out for you in the OP of each kernel (and ROM) for you to find out. Read them because if you don’t, you’ll bork your phone and then your next post will be, “Help. I Bricked my phone”.
Froyo Kernels (see here) and read their OPs. Many can be Overclocked and some can be Undervolted
Battery Friendly Kernels for MIUI/CM7:
Glitch and Bali-CM (there are others but NOOB_IN_N33D gave me these to put in here). Read their OPs to find out more of what they do.
Overclocking/Undervolting –
If you don’t already know what Overclocking is, well it is pretty much self-explanatory. You can Overclock your CPU above the clock-speed that Samsung, T-Mobile governed it at. This can be done with apps like Tegrak’s Overclock (for stock kernels), SetCPU (here and here), CPUtuner,…Generally have to be ROOTed to do these but if you are flashing ROMs and Kernels then you probably already are. UnderVolting is basically what it sounds like too. You are Undervolting your CPU to conserve battery.
This can be one of the best ways for a more advanced user to save battery. Overclocking is great to see those really cool Quadrant scores. Wow!!! But it also ramps up the battery drain, as well as temperature which can shorten your battery’s TOTAL life. If you want to Overclock to 1.2-1.7 just to see what you score on Quadrant or SmartBench, then do it for that time. Most ROMs/Kernels run stable and smooth at or about 1.0-1.2 with minimal effects on battery (as long as you do tweaks in above post). If you decide to Undervolt you can use Pimp My CPU or Voltage Control to do this but take care to step it down slowly until you find the right settings for you or you will see random reboots or phone freezes and those suck trying to diagnose.
***Please note that whether you Overclock or Undervolt, do NOT “Set on Boot” until you know that they are going to work. Otherwise if it doesn’t work and your phone randomly reboots, you will get into a boot cycle (not a bootloop) because you put them in “Set on Boot”. You must test before you should do this.***
Glitch (Kernel for MIUI/CM7) –very brief overview-See its OP for more
- Up to 1.7GHz CPU OC with added bus/GPU OC (Thanks to morfic for the great base of work)
- Undervolting using Pimp my CPU or Voltage Control
Bali_CM (Kernel for MIUI/CM7) –very brief overview-See its OP for more
- OC/UV up to 1.4GHz (Safe boot to 1GHz) [require SetCPU from market]
- Multiple CPU governor, smartass included (default: ondemand)
- Multiple IO scheduler (default: BFQ)
- CIFS support
- Support SetCPU screen off 100/400 profile
NOOB_IN_N33D is running MIUI and is having great battery life for a 2.3.x ROM. He has given me his settings for Overclocking and Undervolting to put in this guide.
**Please note that these are HIS settings for HIS set-up. They may not work for you but it is a good idea to see what I am talking about when it comes to OC/UV**

Memory Management
Did you know that you can also free up some internal memory space by just basic maintenance? You can install a Cache Cleaner from the market. I use Cache Cleaner NG (root) and CacheMate (root) which will clear your cache for you, Cache Cleaner NG will even clear your cache on your SDcard. Open Root Explorer and if you see a bunch of free floating cache files, those need to go. Wasted space. Small in the scheme of your SDcard, but still wasted.
So here we go (best part is at the bottom though):
Ok so you go into XDA on your phone, go to the themes page and look at what and how people are theming their phones or see some pix of someone's SetCPU profiles. All those develop a cache that takes up space on your phone. Now lets say that you go to the market and look through some apps or update your apps (more on this later). This also generates cache, usually up to 2-4mb. Ever try to download something from the market and it says something like "not enough space". This not needed cache may be some of the reason.
Here are some tricks and apps that some of you may know and also some tricks that I have found that I am sure most don't know about.
SOME GOOD LOW MEMORY APPS:
Cache Cleaner NG and Cache Mate (both root and free-Cache Mate has a paid but the free one works just fine.)
Diskusage (free) ~ This one will show you a graphical version of your /data/apps and also you SD card to show you exactly what is taking up so much space. You can click on that item and hit "Show" and it will take you to the app's page in Manager Applications. It also has a root function too that will allow you to see what is in /system, /cache, /data,…
Some sort of file manager to get to some things I'll mention below. (I use Root Explorer)
SOME MEMORY CLEARING TIPS AND TRICKS:
Home Launcher ~ If you have a 3rd party home launcher, see if it has the ability to long-press an icon to take you to its screen in the Manage Apps section. I use ADWex and if you long-press on say Market, it takes me to the same place as is I were to go to Settings->Applications->Manage Apps->Market. Instead of all that, just long-press on the icon and BAM! it takes you there. Here you can clear out your cache for the market or delete the data (if you need to do that). Or clear the cache of the XDA app b/c you looked at too many pix.
Browsers ~ These develop cache that takes up memory and space, especially the stock browser. If you use a 3rd party, you can get the settings to clear cache, cookies, passwords,…on exit. I use Dolphin, but I am pretty sure that most have something like this on them. (side note: most 3rd party browsers once exited will not run in the background unlike the stock one)
Media ~ So you download a bunch of mp3's from the net or click on some pix and save it to your SD card. Or maybe you just felt like wiping your card and having a fresh start. Every time you reboot, you phone will scan media. No big deal, but the more you criss-cross things from PC to phone and back again, it can create a bunch of double files in your media cache on the phone. With the proper placement of .nomedia files (this prevents your media scanner from doing just that, scanning media- i.e. pix, jpegs,…Don’t place a .nomedia in your music, album art or DCIM files**bad).
Every once in a while, I'll hit the Diskusage or go to Manage apps and clear the media cache. Then I got to my file manager and the DCIM->Thumbs and delete the .Thumbnails files (should be 2). Unmount the SD card and remount to start the media scan, pull up the Gallery and wait for the thumbs to come back (depending on how many you have, this could take awhile). By doing this you can get almost 5 mb back if you have a bunch of double scans in your media folder.
AND NOW FOR SOME TIPS THAT MOST COULD NOT KNOW:
LOSTDIR - Lets say that you have your phone plugged into your PC and for some reason you, in a fit of rage, jerk the plug out without unmounting it first. This creates a file that is put into your LOST DIR folder on your SD card. Anytime you don't safely unmount the SD card, it will create a file in that folder. In the scheme of the SD card, it isn't too much, but I don't like having useless items free floating about.
TOMBSTONES - So you are downloading an update from the market and for some reason your phone freezes and the Force Close-Retry-Wait doesn't work out for you. You have to do a battery pull. Frustrating I know and the memory takes a hit too. Every time you have to do a battery pull because of a freeze up or something of the like, it creates a TOMBSTONE file in /data. These are useless and can be deleted. If you are flashing ROMs and are constantly having to do battery pulls b/c market crashes or an app freezes, then you are creating a Tombstone file.
**Here is where your file manager (with root) will help. Go into /data and scroll all the way to the bottom and open /tombstone. There should be some files in there and depending on how many there are, I could be a nice chunk of wasted memory. Just select all and delete. They are not needed. Your internal memory should go up by doing this.
LOST & FOUND - Same scenario, but now go into /data/ cache or /cache and you'll see Dalvik-Cache (don’t mess with this), Lost & Found and Recovery. If you tried to download an app and it got frozen for some reason and had to do a battery pull, the apk will be free floating in there, uninstalled (free floating radical). You can delete this. While it isn't in the Dalvik-Cache folder, it is taking up space. Once you are able to download something completely and correctly from the market, it will populate into Dalvik-Cache correctly and won't be a free radical, as I like to say.

Useful Apps to prolong battery life
These are some apps that will help you get the most of your battery life. I will put a brief descpition of them and you can also click on their names to take you directly to their market link. Note that some of these are ROOT apps and almost all of them also have PAID versions that greatly expand their functionality. Use the free ones and see how you like them and then kick in for the PAID ones if you want. The only one that I really suggest paying for right out of the gate to get the most out of your battery is Juice Defender Plus.
Batstat Widget –
I know, I know. Above I said that widgets were nothing more that monitoring apps on your home page, but this one works great, has low memory and is very, very simple. It shows Charge in %, Volts to know when you are FULLY charged and Temperature F/C to tell you that your phone is getting hot and exactly how hot it is.
BetterBatteryStats –
This app will show you what exactly is eating at your battery. Processes, Running Services, Wakelocks, Partial Wakelocks. It is a PAID app but for XDA users it is free. See here for more extensive details, instructions, screenies, change-logs,... and credits go to Chamonix and his development team for this app.
Batter Calibrator –
When you flash a new ROM, it is always best to wipe the old battery stats associated with that ROM, so you can start fresh as a daisy. How this works is you plug you phone in and charge to 100%, do not mess with it or surf the net (I do this overnight). While still plugged in, hit the apps, grant SU permission and hit the Calibrate Battery button. Grant SU permission again and once done, unplug your phone. Your Batterystats.bin has been deleted. You running your phone down by just using it normally. Most say to run it until it shuts off, but I have had bad experiences doing this, so I let it get to 10-15% and plug it in then. Charge fully up to 100% (again no surfing or games) and you will notice a dramatic increase in battery life.
**Note that this can be done two other ways. You can boot into CWR or Custom Recovery and go to Advanced Settings and there will be the Wipe Batterystats.bin option. Or you can do it manually by going into /data/system/ and deleting the batterystats.bin in there. Any of the three methods work to get the entirely same result in the end. I just like using the app or manually myself. **
Why battery calibration is important and what it is doing.
The app and what it does is more for when you are flashing a ROM and have around 60% and then once booted up fully, you charge it up to 100%. Decided you don't like your ROM and go back to your original ROM via backup, it will show 60% instead of the 100 or 90% you had before you went back to back up b/c you backed up the batstat bin when you nandroided your original ROM.
How about this for an example:
ROM: Deranged9 70% (and you made a backup) Then went to Zendroid, charged and hit calibrate battery at 100%. Used Zendroid for a few hours and decided it wasn't your bag. Your battery is at 50%. You flash back to your Deranged ROM and you know for a fact you had 50% before you flashed back, but now once totally booted, you are showing 70%. This is why you use the battery calibrator after you flash a ROM. Gotta create a new batstat bin for you "fresh" ROM (even though it is a backup).
Recently there has been information debunking this process. I will post it below, however I know what it says, but I also know what I've seen/experienced too. Here is the post by Dianne Hackborn, a Google Dev on her G+ account.
Dianne Hackborn - Jan 12, 2012 - Public
Today's myth debunking:
"The battery indicator in the status/notification bar is a reflection of the batterystats.bin file in the data/system/ directory."
No, it does not.
This file is used to maintain, across reboots, low-level data about the kinds of operations the device and your apps are doing between battery changes. That is, it is solely used to compute the blame for battery usage shown in the "Battery Use" UI in settings.
That is, it has deeply significant things like "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."
It has no impact on the current battery level shown to you.
It has no impact on your battery life.
Deleting it is not going to do anything to make your more device more fantastic and wonderful... well, unless you have some deep hatred for seeing anything shown in the battery usage UI. And anyway, it is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point), so this would be a much easier way to make it go away.

JuiceDefender (Plus) [Since I use JD+, that is what I am going to refer too.]
This app’s ability to kill Radio/Data has NO EFFECT on phone calls or messaging. You will still get that call in the middle of the night you were expecting.
If you set it to custom, the go into the settings tab on the right and then all the way at the bottom, there is two buttons to push, The first in Interactive which will pull up Juice Defender for up for any app that isn't already configured and the other is Configure Apps. This is the one that you can customize on an app-to-app basis where if you are no using an app and the screen is locked, it kills the radio/data traffic for that app.
Say you are listening to IHeartRadio, this you would want either Enable or Enable/off (which means the screen will be locked but the radio/data will be working). Now take the browser. If you are not using the browser, then you don't need it transmitting data right? So you would set that one to Enable (which means that it will only enable data traffic when that app is being used).
Juice Defender only works when the screen is locked (WidgetLocker lock screens interfere with JuiceDefender), don't forget and all widgets are battery drains b/c all they really are is a monitoring app and if it is tied to something like Facebook or Google+, then that data will be running constantly.
Settings:
Enable = Radio/data on when app is in use (front)
Enable/off = Radio/data on for background apps (when screen is locked)
Disable = Disables radio/data traffic completely when that app is running
Do Nothing = What is says
Examples:
Angry Birds = Disable (Here is a little known trick that I use for this and any game with Ads. With this and something like Adfree, no more ads in Angry Birds even though the ads are embedded in the .apk)
Pandora/Jango/ Tune-in = Enable/Off (this will keep your battery temp down when streaming)
Browser/ Market = Enable (not enable/off b/c then it will keep your radio/data open)
Beautiful Widgets = Enable/off
mClock/Clockr = Enable/off
SMS/MMS = Enable or Do Nothing (why would you push disable)
I have been using JD+ for over a year on 3 different phones and multiple ROMs and have noticed a considerable difference in battery life. Just takes some time to figure out YOUR settings and what YOU like. I have also used it on Stock kernel and had no problems either.
LBE Privacy Guard
This will go good with JuiceDefender, as they both prevent unwanted data transfer. Protect your privacy by controlling the permission of each application to access your sensitive data. Block malicious operation from Mal-wares and Trojans. Block unwanted network traffic if you don’t have a unlimited data plan. Find out which application is trying to steal your privacy by checking the security log.
RAM Munchers eat battery too. These will fix that for you.
Autostarts (paid-CAUTION this is for advanced users)
Keep control over your phone: See what applications do behind your back.
Shows you what apps run on phone startup, and what other events trigger in the background. Root users can disable unwanted autostarts and speed up their phone boot.
Watchdog
See what is eating your RAM. Hint: if it is using RAM,then probably it is also using battery too.
Spare Parts
Spare Parts allows you to enable some settings
that are not found in the default setting menu
Process Monitor
List the running process on your Android device.
Long click item to kill application or open application.
Fastboot –
This is a handy little app that kills all your services at once and lets them restart back up. I use this right before I hit the lock screen, so that if any app-services are running that I don’t have configured in Juice Defender Plus they will be killed, frees up about 50-70mb of memory, and then I lock the screen and JD takes over. This one is optional if you want it or not. I like it just fine and it works for me.
Matte Screen Filter –
Puts a sort of Dim setting on your screen. Almost like a display overlay, ok? And I did mean to rhyme those. I don’t use it because I have my display set how I want it but you can.
And might as well hit this thanks button too for the Hat Trick
Change Log:
12/22/11 - Per chamonix (BetterBatteryStats dev) took out apk and input his thread to get most updated version, stats, change log [still free for XDA users though]
1/9/12 - Took out actual APKs and put in market links. Click on the name and it will direct you to the market link for the free version that app.
1/23/12 - Added more battery apps and some RAM monitoring/killing apps.
Very helpful post, Thanks.
I was one of the people asking about this and I just wanted to thank you a ton im gonna try some stuff you suggested, mainly my widgets I have about 3 pages haha. Anyways thanks for the guide

I don't think having more apps on your home screen uses more battery, but having more page does use more RAM. I use only 3 pages but I have 4 or 5 folders set up too. Games for instance has 12 games in it. Social has 3 (you know what they are).
Glad to see it is working for you. Use the apps too and if you decide to get JD+ let me know and I will help you set it up correctly.
Guide looks awesome bro!
Update: Also, thanks for including a link to my guide! Really appreciate that!

Ill type you up something and PM you tonight or tomorrow. If you could PM me a general list of your apps, that would help.
I'm like a crack dealer. First answer is free, the second one costs you (a thanks).
Did you know that you can also hit the THANKS button from your XDA Premium app? Just tap the post.
Ok ill do that and i didnt know that ill be sure to thank you you helped me alot so far thanks for the tip

It is Glitch also but the OC isn't as high as yours but the UC is fairly different especially in the lower frequencies. I think that I might put in something about memory management too but still undecided about that yet. Are you working on the new BIBLE? Talk about a monster task. Let me know it you need help and want to colabo on it. PM me your thoughts. Always here to help bro.
ps: Digging your new graphics too. You've come quite a long way.
Hey guys, I just recently bought my Note 3 and it unfortunately came with NC4. Thanks to Geohot and his TowelRoot I was able to root my phone and install some minor/simple tweaks using Xposed Installer to make my Note 3 usable. Here's a step-by-step of what I did to get my phone to achieve better battery life and performance while also maintaining a decent amount of customization options without installing a full-blown ROM since SafeStrap currently has issues with the OTA NC4 update..
1. Download, install, and run TowelRoot to achieve root on the Galaxy Note 3.
2. After the reboot induced by TowelRoot, install SuperUser from the Google Play Store. You should install one of the following three: Superuser by ChainsDD, SuperSU by Chainfire, or Superuser by ClockworkMod.
You will probably get a notification when you open any of these apps: “The Superuser binary (su) must be updated.” I never bothered to update and every app that has requested root has been working fine for me. Please skip to the second post to see how to update your Superuser binaries if this notification bothers you.
3. Next, install Greenify and SetCPU. Open Greenify, select all apps, and then select hibernate. You can select whichever apps you'd like to hibernate but since this is a post about what I did, hibernate all!
4. Open up SetCPU and set your max clock-speed to 2265 and min clock-speed to 883. Check “Set on Boot” and change “interactive” to “ondemand”.
* I also set a conditional profile that is activated when my screen is turned off (max CPU 729, min CPU 300, Governor powersave). However, this causes some delay when unlocking the phone as the CPUs have to ramp-up. It is actually doing much better on standby but I know that others don’t have patience for that split-second CPU ramp-up to occur, so creating this profile is up to you.*
5. Open up your browser and go to http://repo.xposed.info/module/de.robv.android.xposed.installer. Then download de.robv.android.xposed.installer_v33_36570c.apk. Install the apk and run it. Select “Framework” and then select “Install/Update”. Allow it to install and reboot.
6. Once rebooted, open up the Xposed Installer app once again. Go to the “Download Section” and search for and install ActivityForceNewTask, Chrome New Tab (Xposed), DVFS Disabler, GravityBox [KK], Smooth System Progress Bars, Statusbar Scroll to Top, StopSwitchDelay, and YouTube AdAway.
7. After installing these modules, open up the Xposed Installer app once again and go to Modules. Make sure you activate all of the aforementioned modules you installed by checking each’s checkbox.
8. Reboot your device.
9. Open up Xposed Installer again, go to modules, select DVFS disabler, and check the box within the app that states “Disable TouchWiz DVFS”. Go back to the Modules section in Xposed Installer, select GravityBox and enable or disable any customizations that you’d like. Go back to the Modules section in Xposed Installer, select Greenify and enable Boost Mode and Keep Notifications. Go back to the Modules section in Xposed Installer, for the Smooth System Progress Bars, Statusbar Scroll to Top, StopSwitchDelay, and YouTube AdAway modules, select whatever settings you desire.
10. Reboot your device.
11. Enjoy smoother performance and somewhat better battery life.
Please let me know what you guys think if you do this!
*OPTIONAL* For those that can't stand that their SuperUser binaries are out of date, follow these instructions:
I do know that some of you are extremely anal about these things so I’ll list what you need to do in order to update the Superuser binary.
1. Download http://download.chainfire.eu/448/SuperSU/UPDATE-SuperSU-v1.99r5.zip .
2. DO NOT FLASH IT. First, unzip the file and transfer it over to /common folder and install superuser.apk.
3. Run SuperSU from the App Drawer and let the binary update. If you installed SuperSU by Chainfire earlier, disable KNOX. By flashing CWM you’ll trip KNOX.
^^any clue how the DVFS effects battery Wanam exposed has or defaulted on so I disabled it as well as dl'd the DVFS disabler stop switch and you tube add away..I'll give em a shot thanls!

I'm not sure what you meant, however, I do know that if you have DVFS disabled through Wanam you do not need to download and install DVFS disabler. DVFS disabler is more for performance rather than battery gains.

What should the I/O scheduler be set to in SetCPU for normal and your profile?
Would this work on the N900W8 model running KitKat 4.4.2 with the latest band and kernal update?
Just greenifying a few apps has helped my battery immensely. Before, I was getting terrible battery life.. burning over 3% at idle. Didnt matter if I turned off Google now, location reporting, or any of that stuff.
Now I have everythign on full bore.. syncing, location, google now, etc.. And Im getting about a 1.3% burn at idle. Probably could tune it more, but im satisified for now.
I don't understand the binary update issue. I do it on every device I have rooted directly after installing SuperSU. Never had a single problem... although, I am slightly new to the Verizon Note3 NC4 ownership.
I don't really have any battery issues or performance problems, but I'm curious to try this and see the difference. My device runs a smooth 24 hours with constant use, and I still have 60% by the time I get home.
My apps are all greenified. I use SD Maid to turn off autostart programs. I keep Bluetooth, WiFi, and Full location GPS on all the time, and play some serious games throughout the day. Maybe I have a super battery. Lol.
Im all about performance....so will update after trying this. Thanks for the detail and great post!
Got the idle burn rate down ever lower now.. greenifed everything that the app listed, turned off wifi, gps, location reporting, and google now.

I am pretty sure this would work on the N900W8. Basically, all you need to do is acquire root to do any of this. If TowelRoot supports the N900W8, then yes, this would work for you.

Hmm. I don't believe that you have such great battery life. It seems impossible. However, if somehow you are speaking the truth, I really wouldn't mess with anything.

Your previous statement was that you could use your phone constantly for 24 hours and still have 60% battery remaining. If you do the math, you're saying your phone would use up 40% of its battery over a period of 24 hours. That comes out to an average drain rate of 1.67%/1 hour.
In the screenshot you posted, you have 70% battery remaining after 6.5 hours of the device being on (screen time is not shown). 30% of your battery was used up in 6.5 hours, this gives you a rate of 4.615% battery drain/ 1 hour. What this means is that your battery is draining at 2.76 TIMES the rate at which you stated it drains in your previous post. After using your phone for a period of 6.5 hours, you have 70% battery remaining (or 30% used). What I am assuming you're saying is that your phone will be able to last another 17.5 hours and only use 10% of its battery, giving you 24 hours of use and 60% battery left? This is definitely not believable. I doubt you'd even be using your phone for the remaining 17.5 hours to even reach 60% battery.
I don't see any credibility in your previous post as you said you use your phone constantly. At the current rate of use or drain, your battery would be at 10% its capacity around 20 hours through the day. I don't see how you could use your phone for a period of 24 hours and still have 60% battery remaining. This doesn't make any sense.
i appreciate your write up and work but i have to ask if you are not around a plug often? i use Greenify for the 3rd party stubborn stuff and have for some time but i use the heck out of my N3 including work calls all day and playing Youtube for music in truck for kids and i plug in at night at around 30-35% after killing it all day.
what is the real world need for this? maybe camping or something or is it merely the challenge?

NC4 really ruined everything about the Note 3. My battery life was cut in half and there's just so much lag. The point of this was to improve battery life and performance by disabling DVFS, hibernating apps, and taking control of the CPU. I can't go from 7:30am-2:00am without my battery dying. I'd like to ideally have atleast a day and a half worth of battery that would allow my phone to last 18.5 hours.
Idk. I went from a 30 minute-and-dead Droid RAZR to this. I constantly game with everything on (gps, WiFi, sync, etc). To me this is impressive.
Maybe a bit over exaggerated... but it does hold nicely.
Hey greenify factory mode. I bet your battery will be better. Just hibernate it and insist it stays there and your good.
Thanks for your hard work!! : )
I went from NC2 to NC4. I could go all day get home and still have 50%. I flashed NC4 and my battery would drain without me even doing anything!! I would be at 50% by noon! The SetCPU is well worth the money. I agree with you why should my phone be running at a screaming speed when I have it in my holster? Thanks again this will allow me to use my phone instead of it using itself! ; )

Our G2 is a battery beast already, but a lot of people are still looking for that extra sip that'll help the phone make it through more time in the hand and less hooked up to the wall.
And there are definitely many ways to do just that.
THE LIST IS AT THE BOTTOM OF THIS POST, GIVING LINKS TO THE POSTS CONTAINING THE TIPS. NO NEED TO SEARCH THE THREAD (if I do my job correctly...)
---
There are many topics around battery life like this one which is very rich but nothing that consolidates those advices for a simple search.
I propose to maintain a catalog of tips on this OP, and simply link to the post containing the tip.
A tip will be added to the OP if it's confirmed by multiple users (either through replies or through thanks)
---
Now let's put some ground rules for sharing our tips:
The objective is that the tip can be applied easily, based on the sole post that contains the tip. You need to edit it if necessary, a tip is worthless if one has to read through 2 pages to figure it out.
*
THE DON'Ts
- Tip must NOT be "install this ROM/kernel it's much better".
- No battery-life bragging: No screenshot of your awesome battery life, let your tip speak for itself when we apply it.
THE DOs
- Tip is specific (specific setting, app setting, freezing a particularly useless and battery consuming app,... )
- Tip can require to be rooted but must be clearly indicated
- Tip can be a kernel setup (governor/scheduler, underclocking,...) but you have to be very clear on how to set it up (which kernel tweaker app you use for instance)
- As much as possible, provide screenshots of the target setup
- It is better to update your tip (especially for kernel settings) rather than posting a new one for the same thing.
*
Preferably, use the following template for your tip:
Use the following for your post's subject:
[AOSP/STOCK/ALL][ROOTED/NON-ROOTED][APP NAME/KERNEL SETTINGS/ROM SETTINGS] Short description of the tip
In the details, the following info will be appreciated:
Detailed procedure to apply the tip
Explanation of why it's saving battery
Known disadvantage(s)/limitations
Screenshots

I'll provide a couple of examples below.
I hope you fellow G2 users like this idea!

THE BATTERY-SAVING TIPS
Generic tips (rom settings, kernel settings,...)
ALL ROMS
[ALL][NON-ROOTED][ROM SETTINGS] Deactivate "Allow Wi-Fi scanning"
[ALL][NON-ROOTED][ROM SETTINGS] Adjust auto-brightness level
[ALL][NON-ROOTED][ROM SETTINGS] Check your Fast Dormancy setup (RILJ and DataTracker-FD wakelocks) /!\Carrier-dependant/!\ also on this post with additional info
[ALL][NON-ROOTED][ROM SETTINGS] Disable/reduce window/app animations
LG-BASED (STOCK) ROMS ONLY
[STOCK][NON-ROOTED][ROM SETTINGS] Disable unused stock apps also on this thread with many suggestions for apps to disable
[STOCK][NON-ROOTED][ROM SETTINGS] Disable Knock-On (external thread)
AOSP/CM-BASED ROMS ONLY
App-specific tips
[ALL][NON-ROOTED][GOOGLE SEARCH] Deactivate the "OK Google" detection from any screen
[ALL][NON-ROOTED][GOOGLE SEARCH] Deactivate location reporting / history (NlpWakeLock and NlpCollectorWakeLock wakelocks)
[ALL][NON-ROOTED][FACEBOOK] increase the refresh interval
[ALL][NON-ROOTED][LUX] Use Lux app to improve auto-brightness
[ALL][NON-ROOTED][ROM SETTINGS] Deactivate "Allow Wi-Fi scanning"
*
In the Wifi connections screen, open the "Advanced Wi-Fi" from the menu
Uncheck "Allow Wi-Fi scanning"
This will prevent the location services (whether google or else) from scanning for wifi network for improved location accuracy when Wi-Fi is OFF. I have seen no degradation in the functionality of Aviate, Tasker and Google Now with that option deactivated however it does save a lot of wakelocks (wlan_rx_wake). This will not change the Nlp*WakeLock though.
*
This is mostly for people living in metro areas where cell coverage is dense and sufficient to have a decent location out of cell towers only.

}
[ALL][NON-ROOTED][GOOGLE SEARCH] Deactivate the "OK Google" detection from any screen
*
With its last update Google Search allows the "OK Google" detection from any screen. This is a battery sucker.
*
Open Google Search
Open the settings from the menu
Go to Voice > "Ok Google Detection" > Uncheck "From any screen"
*
This will prevent the AudioIn wakelock which can be significant and that not everyone might need (I for one use a search button on the navbar which opens Google Now voice input when long-pressed, the effect is strictly the same)
[ALL][NON-ROOTED][FACEBOOK] increase the refresh interval
Most people could probably live with auto-refresh of their Facebook happening less often.
Head to the settings of the app and increase your refresh interval. That's a little bit less waking up the device and using the data connection.
[ALL][NON-ROOTED][ROM SETTING/LUX]
Set custom automatic brightness curves using the Lux app (app store). Link desired brightness levels directly to the device's light sensor readings.
Default auto brightness settings in LG's ROM are finicky and depending on your preferences, you may be able to live with a darker screen.
Lux tutorial and setup should guild you through setting custom curves. Additionally, you can allow other apps to over-ride the Lux settings, for example, if you turn on LG's battery saver function and force the brightness automatically to a very low %.
Disadvantage is the need to keep the persistent icon to prevent the app from being killed. Increasing the priority when rooted can help, but it still seems to be occasionally killed.
[STOCK][NON-ROOTED][ROM SETTINGS] Tune down the brightness in auto mode
Auto-brightness can be adjusted, that is when active, use the slider to have an overall brighter/darker screen. The slider is not just for manual adjustment.
No downside on this one
[ALL][NON-ROOTED][GOOGLE SEARCH] Deactivate location reporting / history
This one is a big battery sucker, although it seems that it's more noticeable when running Dalvik runtime than ART.
What Reporting does is periodically polling your location so Google Now will be location-aware and provide you local suggestions, travel time to your home,...
History, on the other side, will save these location reports and allow Google to build your location profile (most visited places typically) and for instance let you know ahead of time when it's time to leave for work depending on the traffic or transit status.
Now, if you don't care for these location aware suggestions and/or your concerned about your privacy, turn these suckers off.
This will typically affect the wakelocks "NlpWakeLock" and "NlpCollectorWakeLock" which should go down dramatically unless you have other location-aware apps.
Open Google Settings, under location turn off both reporting and history. You will save a significant amount of juice.
Obviously the downside is limiting Google Now functionalities but those not depending on the history will be available "on demand", that is when you open Google Search (the location will be determined then only and you'll get your suggestions, instead of these happening in the background)
[STOCK][NON-ROOTED][ROM SETTINGS] Disable unused stock apps
This one will be a try-and-see. I for one don't use smartshare at all.
And it has happened that I'd have that Smartshare.MediaServer going all crazy and sucking up to 15% of my battery for no apparent reason.
So I disable it and if it doesn't really save a lot of battery on a day-to-day basis, I'd say it can't hurt anyway.
People may want to do that using Titanium or ROMToolbox, I guess that is a personal choice.
If you experience any sort of issue (haven't myself) then simply re-enable it.
I got a thread on this in my signature. Some thing are general, other things are more specific. If you choose to use any, feel free to do so.

I'll definitely try these out and include them!
Since @vPro97 got the wakelock covered i guess ill just delete my part in all of this ?
Thanks for that. The FD is included in the previous post (not mine) but I haven't had the time to update the op yet. I need to figure out which carriers have are applicable for the FD tip though
However I did a not of research on the fast dormancy and it seems that if you enable it on a carrier that does not support it then it's a battery killer. By default it is NOT activated unless your carrier did activate it in which case it's likely that it does support it.
If not activated then it simply does not save battery as it could if your carrier supports it.
That is, at least, my understanding
Thats correct @AnteusFogg.. in my situation every rom i flash, i end up with a FD status unknown and have to manually switch it off for the wakelock to disappear on my phone/operator...
I guess those tips will make for an excellent sticky thread with more to come and an organized OP for the new users

[ALL][NON-ROOTED][ANIMATION SPEED]
If you want your phone snappier and using less battery you can easily try reducing the amount of time allowed for the animations. Just enable the Developer Options, scroll down and reduce or even disable the animations. If you multitask and need allot of Screen On Time, this tip can save you plenty of juice.

Never thought of that as a battery saver... It does make the phone feel snappier but battery saving really? Did you observe a noticeable improvement?
Introduction
As the owner of an Xperia Z3, I found myself missing Stamina Mode after flashing a CM12 ROM. None of the battery apps in the Play Store worked the same way - most of the ones I found merely disabled Wi-Fi/data while the screen was off, along with managing auto-sync, but I still wanted whitelisted apps to be able to access the internet.
I spent a good 12 hours straight working to replicate the basic features of Stamina Mode, and now here we are: Power Nap for Xposed!

Compatible with any Android device running 4.1+, with root and Xposed.
Power Nap for Xposed is the best app for saving battery. When your screen is off, Power Nap maximizes your device's deep sleep time by stopping services, alarms and wakelocks from waking the device when the screen is off. This means you can leave Wi-Fi/data on and still get the notifications from apps you have whitelisted, while all others are unable to wake up your device, leading to an increase in your battery life.
Power Nap for Xposed also has a Low Battery Mode, where you can selectively functions to save power when battery level is low.
Power Nap for Xposed is inspired by Sony's Stamina Mode, but accessible for all Android devices 4.1 and higher. This app requires root and Xposed.
Be sure to whitelist any third-party alarm clock app you are using, or it will be prevented from waking up your device!
Permissions
android.permission.INTERNET: this is for Crashlytics only, which will automatically send me stack trace logs if the app crashes due to something non-Xposed related. No other information is being sent.
android.permission.WRITE_SETTINGS: For Low Battery Mode, to change screen brightness and screen display timeout
android.permission.READ_SYNC_SETTINGS: For Low Battery Mode, to check if auto-sync is on/off
android.permission.WRITE_SYNC_SETTINGS: For Low Battery Mode, to turn on/off auto-sync
android.permission.ACCESS_WIFI_STATE: For Low Battery Mode, to check if Wi-Fi is on/off
android.permission.CHANGE_WIFI_STATE: For Low Battery Mode, to turn on/off Wi-Fi
android.permission.ACCESS_NETWORK_STATE: For Low Battery Mode, to check if mobile data is on/off
android.permission.BLUETOOTH: For Low Battery Mode, to check if Bluetooth is on/off
android.permission.BLUETOOTH_ADMIN: For Low Battery Mode, to turn on/off Bluetooth
android.permission.RECEIVE_BOOT_COMPLETED: For Low Battery Mode, to start a service that monitors the current battery level (if LBM is enabled), when the device is finished booting
Installation Instructions
To get the app, you can either opt-in for testing on Google Play (and/or join the G+ Alpha testing community if you're interested in helping out by reporting bugs and sharing your experiences), or simply download it directly from the Xposed Module Repository. You may need to change "Versions to be shown" to "Experimental" in the Xposed Installer's Settings to be able to download it using the app.
The latest APK version is also attached to the "Download" tab of this thread, but you will not receive updates using this method.
Final Thoughts
By using Power Nap, you can expect to see as little as 0.2% battery drain per hour (if you don't have many apps whitelisted) during standby. Results may vary by device and depending on which apps have been whitelisted.
Since it's in Alpha mode, please feel free to leave feedback and report bugs. If you need any clarifications on any aspect of the app, please leave a comment!

i mostly get blackscreen during incoming calls. power nap does not let the system wakes up so.
thanks in advance

found this on github -*-*
perhaps also worth mentioning, in my search to find this problem, I created a file to run at startup which sets selinux to permissive and chmods the xml files for powernap to global read write (i don't care )
/system/su.d/permissive.sh
#!/system/bin/sh
setenforce 0
chmod 777 /data/data/net.jzhang.powernap/shared_prefs/*.xml
--*
i think the edit_check talking about this.
I haven't used this module for a long time. On Marshmallow+, you don't need it, because Doze mode is built into Android. But on anything up to Lollipop, PowerNap is still beneficial. Having SELinux in permissive mode makes this module work fine. If you're on Marshmallow+, check out ForceDoze/NapTime/Greenify/Doze Settings Editor. Out of those 4, I personally prefer ForceDoze, but they're all good. These apps let you fine-tune Doze mode. The best thing about these apps is that they don't require Xposed, you can use them with root. In some cases (like ForceDoze) you can set it up with ADB instead of root, which lets you reap the benefits without rooting. In terms of Doze mode vs PowerNap, I would say doze saves more battery overall. You can use both, but it's pointless, and your battery life savings will be minimal at best.
wow! This is great! Testing mode: ON :good:
Man ..
I spent the whole week looking for something like this .. thinking like I was thinking before I knew about #xprivacy ; there has to be someone thinking the same way am thinking with the knowledge to actually create it ..
Thank you
Will it work on android 5.1?
this looks fantastic!
never use sony devices before, let's say if I add whatsapp/bbm/snapchat to app whitelist I still could get notification or chat while the data will mostly turned off?
isn't deep sleep battery saver works with turning off data/wifi and turn on again for specific minute in time interval?
Are you planning to bring JellyBean support?

It should work, as long as you get Xposed working!
It's been confirmed that it DOES NOT WORK with 5.1 due to ART changes.

Yep, Power Nap will let your whatsapp/bbm/snapchat receive notifications while all the other ones will be prevented from waking the phone.

Yes, I can theoretically support all the way down to Gingerbread, but I wanted to start off with a smaller audience because I can't test with any older devices yet. But I'll definitely be adding Jellybean support soon!

I am not discouraging your work but isn't it quite similar to Amplify?
Can you give another method for downloading the app since I am allergic to Google+?

It may be similar, yes but Amplify works differently. In Amplify, you choose to disable/control things and in the hands of noobs, it can lead to bootloops. Here, the Dev chooses the things that can be stopped and being a Dev, he is experienced and knows what he is doing. In addition, Amplify works 24/7 whereas this app will work only when screen is off.
Plus this has a white list which will help you to decide what to allow.
I like the concept and would like to try it if the Dev offers another method of downloading the app.

Which leads into the next question, can this be safely used alongside Greenify or is it redundant?

Amplify allows wakelocks/alarms on a schedule (every 5 minutes while the screen is off), and uses a blacklist as opposed to a whitelist. Power Nap stops the wakelock/service/alarm from waking up the phone at all. I'm not sure if you can blacklist a specific app with Amplify, but with Power Nap you're able to control which apps are whitelisted, and any service/wakelock/alarm belonging to a non-whitelisted app will be blocked.
Plus I'll be adding more features to make it a general power-saving app as well, so look out for that soon!

Greenify hibernates apps while the screen is off, but I believe with Greenify you can hibernate apps while the screen is on as well(aka phone is in use). Power Nap only "hibernates" when the screen is off. So depending on what you use it for, you can either get rid of Greenify or keep it. But even if you use it alongside each other, it shouldn't have any ill effects.

The only reason I'm using G+ is because the app is in very early alpha (while it works, it's not pretty and Endurance Mode is the only feature right now). By joining the community and then downloading the app through the Play Store, I'll be able to get basic statistics (no GAnalytics yet) and crash reports.

It might take a while for it to show up for you. It did the same to me when I tried to view it in the Play Store at first!
Some modules do work over 5.1 with the Xposed SUPER ALPHA, does this one works? if someone tried, plz share with us :good:
Thanks to @biktor_gj and his development skills, it all started here, below are the things I've managed to get working either partially or fully. Once a stable CM 13 is released, this post is likely to be updated.
Fully charge your watch first. Things below will take considerable time to configure to your liking; it's better to have enough battery to fully test the configuration.
1. Because CM 12 is a 5.1 build, you'll have to get Play Services from a Lollipop apk (I got mine from apkmirror), and install Gapps (mine is a modular nano; it will take 10-20 minutes). I suggest wiping Dalvik cache from TWRP after installing Gapps - my unit was very unresponsive until I wiped Dalvik and it rebuilt all 98 apps (your app count may vary).
2. Push notifications - get the Desktop Notifications app. Until Bluetooth is working properly, get Desktop Notifications (yes, it's only via WiFi tethering, it's cloud-based, which sucks, I hate it, but oh well). Configure and test it on another Android device first (provided you have one) or a computer, so that you can successfully get notifications to begin with and aren't wasting your time on the tiny 200-dpi Gear S screen. Keep in mind that because it's Wifi-tether, the battery life may suffer. Because I'm still testing various things on and off (primarily with Tasker), I haven't had a chance to test the battery from 100% in a fully-working state.

3. Tasker profiles on the watch; this section is likely to be updated every now and again, as I tweak more and more settings. You have to install Tasker on the watch.
3.1. Watch notifications -> Wake Device and Vibrate.
Get Secure Settings as well as Auto Notification from Play Store, go to Tasker and create a new profile. Profile details/conditions are "Notify" and "Display State Off". "Notify" comes from the Auto Notification module/plugin. Configure -> Action Type = "Created Only"; Persistency = "Non-Persistent", Apps = check "Desktop Notifications". Task would have Vibration and Wake Device (Secure Settings -> Actions -> Wake Device). Vibration duration is whatever you choose; mine is set to 200ms.
3.2. [not ideal but most reliable] Cover to Wake -> upon covering the device light sensor while the screen is off, it wakes the device and briefly lights it up for a couple of seconds so you see the time, etc.
Profile conditions are "Light Level 0 to 1" and "Display State Off". Task is - "Wake Device" from Secure Settings. Configure that as you wish.

I appreciate your advice! I personally like to install (no frills Cpu) and clock the device do 300-600mhz for extra battery savings. You said it right, we are lucky to have Biktor!!!

Don't we have to have a compatible kernel for that? If so, do you know we actually have it?
No frills Cpu works like a charm, I have been using it since day 1, I test it on every device I get honestly its the best interface with the most compatibility, depending on Your kernal it works on the note 5 lol

Not at all, I apply on boot, games don't play well when it's clocked that low on powersave but it lasts and the more updates the better it gets stability wise, I always thought no frills caused some of the issues. Enable SU in developer settings if you have not

1. For some reason, the shaking profile isn't working as well as I had hoped. I'm looking into either adjusting it further, or incorporating the accelerometer "face-up", proximity or pressure sensing profile, which I'm not entirely sure would work since there may be no sensors for that on Gear S.
Accelerometer isn't that great, either, see below - the watch is on its side, yet the accelerometer says that it's facing up.
2. Tasker light sensor isn't working for me either - with the condition of "Light sensor values 1 through 5 + Display State Off" followed by "Wake Device" task, nothing is happening when I cover the light sensor while the device is off. I'll have to do a bit more digging on how the light sensor is handled in Tasker.
3. Neither proximity nor orientation sensors are being detected by the Sensor Test app. My hopes for the pressure sensor quickly vanished when I discovered that it's not the screen pressure but atmospheric pressure.
4. The light sensor monitoring was off (genius) - got the light sensor to work. Set the profile to "Screen Off + Light Level 0 to 1" -> Wake Device. So far, this seems to be the most reliable waking option. EDIT: unless you're wearing long sleeves, of course. Just can't catch a break with this screen wake.
Are there any other apps that you'd recommend for this watch? I currently use calendar widget: month, and mighty text. I had to change the dpi to get mighty text to scale properly. Coincidentally, changing the dpi also allowed me to use the calculator widget.

I'll be waiting for the CM 13 update. If Bluetooth becomes a reliable tethering option (right now I'm paired to the phone but cannot browse internet) and sensors get a better implementation, I'll think of more things to do. So far the shake sensor presents a concern, as it works on the first try but stops on the third or fourth attempt (the shake movement of the wrist is literally identical).

I recommend either dynamic notifications, or acdisplay for a better lockscreen. You can configure them to turn on the screen for a few seconds when you get notification.
Set their background to pure black for battery savings.
Edit: they're nice but I have to say don't bother with the little ram we have. I feel kitkat rom would've been better to port to Gear S
Edit 2: Install this https://play.google.com/store/apps/details?id=org.azasoft.free.swapper set it to 120mb. helps with ram.
Also this https://play.google.com/store/apps/details?id=com.chummy.jezebel.blacked.out and apply in themes app. helps with amoled power savings
Not available on "Next" to update the application .apk. This is due to the resolution of 200dpi. Therefore it is necessary to change the settings at 180dpi resolution. But it comes a full restart of the interface. After the installation is restarted again to return 200 dpi. Is it possible to update the application without changing the dpi? I have no established GAPPS for ideological reasons.

There's an experimental lollipop version of app settings xposed module that lets you choose dpi of specific apps. I'll post a link when i can get to a computer. (At work). Then you can set dpi of package installer only
According to the link below, pushbullet allows you to sync notifications between two or more android devices, so this should have the desired feature of receiving notifications from the phone that the Gear S is paired with.

I think it's a paid feature and works through internet though. I actually installed SWAPPLink and it does notification through bluetooth connection (It crashes often, but notifications still work, just hit ok on the crash message and it'll keep working)
Also I got it from the Swapplink Google + community, where he posts beta versions. I don't know when last the play store version has been updated.

Hi guys! I dont know if this thread is alive anymore. But I'm currently using the latest? android 5.1.1 on my gear s and its awesome! compared to regular tizen...
For notifications i'm using m2d sender / receiver. it works perfectly! pushes all notifications from my phone to my watch. in the new update you can set m2d receiver up to be used on a watch. works very well!=) check it out!
The only issue I have with running android on is the RAM. i only have amax of 100MB ram free! Anyone being able to free up more?
Hello,
how can i use on CM the Heart Rate Sensor and UV Sensor?
there is an app for bluetooth notifications between gear s cm and android phone?
How stable is cm on the gear s?
