How can I make my battery last longer? I am using set cpu and various profiles to give me the best optimization I can, however my phone barely makes it 10 hours with light use *1hr web browsing, avid txting, light music listening via music on phone ~ 1 hr as well.* I'm not faulting the phone. I just want to know what can be done to get the most out of the stock battery as I see people getting results twice as good as mine and just done get what I'm doing wrong here.
Thanks for the help in advanced.
I have the exact same problem as you. Are you using unnamed with Enthropy's experience kernal as well? I'm about to flash cm7 to see if I can get better results.

I used cm7 for a while now using UnNamed and cm gave marginally better battey life but
Just use the dang phone . You dont need to do anything special for great battery life. Try a factory reset if theres a problem though. Im rooted on cog beta 4 getting amazing battery life. I talked my mom imto getting this phone over the new iphone and hers is completely stock and she knows nothing and doesnt close any apps and gets the same amazing battery life as i do.
Reset and use it. If you cant get through a day of heavy use the phone is defective.

+1....or you have wakelocks. Find BetterBatteryStats and CPUSpy. BetterBatteryStats will tell you if something is preventing the device from going into deep sleep. I like to use "wakelocks since unplugged." CPUSpy will tell you the amount of time your device spends in each frequency, including deep sleep. For this, you'll need to reset the timers each time you unplug the phone.
Its add easy as flashing cm.... I went 15 hours and still had 60% left. with OC. Nothing else special (aka no juice defender our set CPU). The only trick is deleting everything in the dcim folder (known medias bug ) you'll see 1% battery loss per hour, with fb and GV sync

BBS sometimes misses wakelocks, for even more info, grab the contents of /proc/wakelocks and post them here.
my solution: keep a charger with you anywhere you go
I have a car charger, home charger and work charger (as do most people)
Thanks for all the replies. I'm sure there's go to be a work around for this
Not sure about a workaround. From everything I've seen, the max battery life is around six hours when the screen is on. Basically, if your screen has been on for 4-5 hours, it's time for a recharge.

Well based on all I've read it seems like the battery is a mixed bag depending on the OC profiles, roms and kernels being used with the device.
Is it true that setting a screen off profile in set cpu will cause the device to not be able to enter a deep sleep mode and thus will kill the battery faster?

Not true. It is true, however, that on stock kernels and ones without the "sleep of death" fix, setting a screen off profile with a clock limit lower than 800 MHz can cause "sleep of death" issues. Right now I think only my kernel and the Cyanogenmod kernel have the SoD fix.

Thanks for clearing that up
I'll post here as I don't have enough posts for the development forum yet.
I'm running Entropy's 16th exp kernal, and Cog4 and I noticed my battery draining far too fast, CPUSpy then showed that the phone simply isn't entering deep sleep. I had previously been undervolting with Voltage Control but I uninstalled the program just to be safe, still not deep sleeping. I also uninstalled Widgetlocker, and I don't think I have any apps that would cause infinite wakelock. What are some possible causes of this issue? Just so I have an idea where I should be changing things.
UPDATE: Reflashing the kernal fixed the problem for a while but then I reinstalled voltage control and now I seem to have it again. Uninstalling and reflashing again however, did not fix the problem. I am utterly confused
On another subject, has anyone actually noticed better battery life after undervolting?
Freaking SWEET! My battery lasted 33 hours and 13 minutes! I've only owned the phone for 3 days now and this is off of teh very 1st FULL charge! Usage was between light & moderate. Data sync on, Wifi On, GPS OFF, BT OFF, FB Data Sync OFF, Capacitative buttons set to light up only in the dark & NO haptic touchback...mmm, can't remember what else I tweaked at the moment but I think that's fantastic battery life! I'm upgrading from a G1 that couldn't last more than 17 hours when it was on standby ONLY with maybe 2 phonecalls and less than 20 text messages. I usually only averaged 6-8 hours and with SIMILAR usage in the last couple of days, I've been able to get 33+ HOURS? ^_^ <-- I'm very, very happy so far! This is on a stock root - NO custom ROM for me at the moment...I'm actually digging TouchWiz 4.0 which I thought I was going to hate when I played with the previous version of TW on the T-Mo Vibrant. (yes, my G1 was running CM 7.1 and battery life still sucked and I went through 2 different aftermarket batteries w/o any luck!)
Don't know what the voodoo in the programming is with this bad boy, but I think Sammy did a nice job this time!
The best thing you can do is having "Autostart" to prevent App to start automatically. I saved 25-30% on my SGS 1 and the same on my SGS 2 (i777). My son on the I9000 SGS 2 saved also 30%.

Check for wakelocks in BetterBatteryStats, and if that doesn't find anything, do the following in an Android Terminal Emulator shell:
Code:
cat /proc/wakelocks > /sdcard/wakelocks.txt
or better, using ADB (Google it and if you're on Windows, Droid Explorer)
Code:
adb shell cat /proc/wakelocks > wakelocks.txt
Then post wakelocks.txt here
All the apps,camera n everything works on that rom? ??? I installed cm7 bt now stock it cuz some apps and camera app didn't work.

If you or anyone else wants to get PHENOMENAL battery life of let's say 15 hours of use and still have 40%-50% battery left on a regular stock battery on the Rezound, just follow these steps:
1. Go to Settings - Power - Power mode Choose "Economy"
2. Back at Power options, Click on "Economy mode setting" I left the setting as "Normal" which means that the only box that was unchecked was "Disable background data"
3. Back at Settings, Click on "Accounts & sync" Uncheck the "Auto-Sync" box, but leave the "Background data" box checked.
4. Using whatever Screen Brightness tool you want to, set the screen brightness to no more than 20%. The only exception to this is if you are out in the sun and really need to see your screen while in the sun (navigation or etc...). Other than that, I never need it to be brighter than 20%.
5. Because of these changes, you will have to manually "Refresh" your email app to check for new mail. Other than that, everything data wise should work as normal.
I always have my 4G LTE and GPS on and ever since I did this, I have been getting RIDICULOUS battery life! This best it has been is when I charged it completely and unplugged it at 10pm and the next day around 1pm I still had 62% battery left. On a normal basis where I take it off the charger at 8am, with normal use (3 hrs of music, 1 or 2 of web surfing and video watching, 1 hour of phone calls, and Google Talk and Google Voice and GMail all day *literally*) I have about 50% battery left at 7pm.
Disclaimer: I have "Bump Charged" my battery before making these changes. However, I never saw this type of battery life until I made the above changes. Also, if you constantly watch video (Youtube or etc..) you will not see quite this performance, but it will still be much better than what you are currently experiencing.
Enjoy
Turn off data and you can get multiple days on battery
Screen Filter
You can also use the app Screen Filter to turn off the bottom row of leds.

So you have an extended battery then? If so, might be good to include that info in your post just to be clear. Not that that wouldn't help any battery, but the stats will make more sense and the answers to your poll may be more accurate since people might think their results aren't as good as yours if they're using a regular battery.
I'll change my settings and try it since I don't need instant notification of emails atm. Thanks for the tip.
When I change the power setting to Economy, I lose 4G.
I am eager to try this, but I gotta have my 4G. Any suggestions??
Turn it back to 4g in network settings

You can bump charge the normal battery as well.
So what exactly do the power modes do? Are they just presets for certain settings? or do they control CPU scaling or anything else? I've always just left mine on normal with auto sleep enabled
Edit: I also wonder what affect the "auto start task manager on startup" option does exactly, and if having that on improves battery life, or if it is referring to the task manager in the notification bar quick settings

I used that app for quite sometime on my Incredible when I ran a sense rom (cm7 allowed me to set the buttons leds off on its own).
Fyi though, when screen filter is active, I am unable to install an app. When you go to install an app, and you are on the screen that shows the permissions with the install button on the lower right, I have been unable to click the install button with screen filter running. I just run screen filter again to deactivate it and the install goes fine, then I just run screen filter again to get it running again.
It's a hassle, but a small price to pay to get those led's off if you dont want / need them.

I am curious about this as well... I know the kernel supports multiple governors for CPU scaling.
I am also not sure what the task manager is that it refers to. It might just start the app in the background.
No one know?

Tap the graph and it shows a bar that shows signal strength over time. That would help to figure it out.

Stock battery
I have done everything from Autostarts to managing my processes constantly. I played hanging with friends, got on here, and texted.
I posted an updated battery usage. I have lowest brightness, lowest image brightness, 15s timeout, etc.
i would probably switch to conservative governor vs powersave
This isn't typical battery life
I'd advice you to use better battery stats and cpu spy to se what's causing your battery to drain so quickly
Sometimes I notice "back up" in bbs, and this casus my phone to drain within a day
Hanging with friends does consume a lot of battery, but I play it too, and this does not cause that much drainage..
I have ICScrewed and with a heavy usage, my phone usually last for 1.5 ~ 2 days
With moderate call/text and idle, it lasts for 4 days.

Dang that is high! Are you sure about that? :O At medium usage /w unnamed i only get about 18 hours total. It was similar with ICScrewed too
Holy crap. I'll look into better apps. Could UnNamed be the culprit? Or the kernel?
Should I buy a new battery? The life waslike this for the few days I was stock, I think
I average around 17hr, on a good day I'll get 20h. I also recommend better battery stats, great app to see what's keeping your device from going to deep sleep.
Another great app is lbe privacy guard, you can deny certain apps and games some of the permissions they want (disabling GPS on those that really don't need it etc).
I'm on unnamed so that isn't the issue. Might be the kernel, just check the kernel wake clock in better battery stats to check. I'm on entropy's latest dd, while i do feel i got better battery life on the kernel with the latest unnamed ROM I'm not to sure if it's the kernel or something else.

I'd be curious to see your graph. My battery is dead now, but tomorrow I'm going to get on and upload Better Battery Stats to my phone. I would've paid for it on the Market, but I couldn't find it when I searched. I'm curious to see what other people think. I switched all Powersaves to Conservative. Is OnDemand bad for my CPU as it constantly trips from 500MHz to 1.2GHz? Should I consider going to 1GHz?

I agree. This is my latest battery cycle of what I consider "moderate" use
What I'd consider light usage (about 10 minutes of voice, between 5-10 minutes of cellular data, 10-15 texts, and about 20 minutes of total screen-on time) I get about 35 hours.
I have managed to almost completely drain my battery in about 4 hours though... Thanks Game Dev Story!

I realized I forgot to turn off data when I'm not using it, but I installed better battery stats and I didn't really see any wake locks. Should I try a different kernel? Any opinions on an efficient one? NOTE: I already got the yellow triangle for using the Odin way, so I'm fine with doing whatever to this phone.
I added my better battery stats shots. I guess today would be called a very light to light day.

I see two very top wake locks have kept your phone from sleeping for an hour..
That is a significant amount.
Also, use cpuspy to see how hard it's been working.
I would try to get rid of those top two wake locks...
Oh crap! I didn't see them until you brought it to my attention. That explains some of the idle drain. I'll look into CPU Spy. You guys have been so helpful!
Your kernel wakelocks had no data, probably due to BBS being a fresh install. A full charge should set a proper reference point.

If something's holding that many log wakelocks, something might be spamming a log somewhere.
I can't find anything to help with those two either. Or would seem that the keyguard might have something to do with text messages, but I can't see anything that would spam the log. Where might I be able to read this log?
Also, I'll post my CPU spy stats toward the end of the night. It's looking like it spends most of its time at 500MHz.

I've seen a lot of users' postings of battery statistics (screen shots) and they are all considerably better than what I am getting. The biggest difference I see is in the amount of battery drain from "Android System." What I see posted is between 9% and 13%. However, my batt stats show the Android System draining 60% of the battery.
So, what am I doing wrong? I'm still kind of new to Android. Is it the widgets? I've checked running processes verses what apps are draining battery life and nothing is running that drains like the system does.
Further info: I am currently running the 7.18.12 build of Diet ICS, but I was seeing this behavior on stock as well. Some widgets I use: Astrid premium tasks widget, Evernote, doubletwist, slacker, 3D clock/weather, a widgetsoid switcher, and APW Calendar.

How often do your widgets that gather info refresh? Try scaling down on some widgets and see if that helps. If not, try to flash stock with odin and start over. I was having some problems with my phone when I first got it (MTP specifically) and I falshed stock and everything started working fine. Also, if you are using Google Chrome, make sure you have the experimental feature of using the gyroscope for tilt scrolling set to off....it is known to drain battery.
Hope this helps :good:

Maybe I will try flashing stock if I have time today. I reset my battery stats in recovery mode when I took the phone off the charger this morning, so we'll see how today goes.
I looked into the widgets and the only one that refreshes data on a schedule is the clock/weather. I'll try a different one or just not use the weather.
Great tip about Chrome. Didn't know it did that.
Do I actually need to calibrate the battery? I tried the method of letting it die and charge back up a few times and I've tried recharging once it gets down between 70-80 percents life. I'm not sure which method helped, but I did notice an improvement.
Thanks again for the help.

I have my display off auto-brightness and on a low setting, I probably utilize the task manager 50x a day and clear the ram as well, cpu sleeper is always activated, gps/sync/auto-rotate/wifi/bluetooth is always off unless I need them, and I have power saving mode on most of the time.
With all these settings off and I am a heavy texter/caller/browser/emailer, my battery lasts from 7AM-1AM and I am at 30-40% at the end of the day!

Never mind! Just searched" CPU sleeper" on the Play store and--voila!
On another note, I'm so glad I got a device with a huge support community. Coming from iOS, it's nice to feel part of a collective effort again and get such great advice. I know there are a lot of iOS forums and there is some great work done through those communities, but those seem so trivial compared to what is done through XDA and the level of helpfulness is unparalleled here.

Do I actually need to calibrate the battery? I tried the method of letting it die and charge back up a few times and I've tried recharging once it gets down between 70-80 percents life. I'm not sure which method helped, but I did notice an improvement.

I read somewhere in the forum that these batteries actually like to be constantly charged up and not let die completely. There was no explanation for this but I will research it because I am curious. With my old Captivate, i let it die then fully charge to extend the overall life of the battery.
How is your battery so far?

I've applied all the tricks folks have shared here and have flashed the Diet ICS rom. I am going to take screen shots of my usage data on a daily basis and see how things fair. I'll post my results here. Here is one from last night before really getting into all the tricks and the new rom. So, maybe this is my "before" shot in this documentary of a noob's journey to better battery life.

I've seen a lot of users' postings of battery statistics (screen shots) and they are all considerably better than what I am getting. The biggest difference I see is in the amount of battery drain from "Android System." What I see posted is between 9% and 13%. However, my batt stats show the Android System draining 60% of the battery.
So, what am I doing wrong? I'm still kind of new to Android. Is it the widgets? I've checked running processes verses what apps are draining battery life and nothing is running that drains like the system does.
Further info: I am currently running the 7.18.12 build of Diet ICS, but I was seeing this behavior on stock as well. Some widgets I use: Astrid premium tasks widget, Evernote, doubletwist, slacker, 3D clock/weather, a widgetsoid switcher, and APW Calendar.
Thanks for any help or suggestions.

Have you tried using the CPU Sleeper app?
http://forum.xda-developers.com/showthread.php?t=1745516
I found that it does a great job of preserving battery life when the phone is in standby. I used to notice my battery draining really fast over short periods on standby (phone would be hot to the touch). After installing this, I have not encountered that problem again. I get 16-20 hours of use on moderate usage. LTE, gps, and sync are always enabled. I DO NOT have the phone in power saving mode and I seldom use wifi. I used to get 10-12 hours of battery life on the same usage before. I am running the rooted version of the stock rom from my carrier.
CPU sleeper app works great for me. I am in a non LTE area but get incredible battery life, last all day usually with around 50% left. An order of magnitude better than my SGS2

I am using CPU Sleeper now, thanks to the advice of a previous poster on page 1. Good to hear it works for others.
I had the SGS2 as well and the S3 is definitely better.

Hi all,
I also notice this and this were the steps that I did and seems to help me to reduce this process to like 5 %. I'm on Sprint S3 but should be the same for the all carriers.
Go ahead and open Talk application. You should see your account in green (I'm not using this application) then hit the menu and then select sigh Off. Make sure that your account changes to Offline (sometimes it is change back it self so open one more time make sure that it says Offline). Then what else I change is in wi-fi advanced options: under Keep Wi-Fi on during sleep I choose Only when plugged in option. then I reboot the phone and from now on (almost 2 days) my Android system process show up only 5% of usage and my battery life improve significantly. I hope this will helps.
Thanks
Those are great tips. Thanks. I will say I've gotten increasingly better life since employing other tips discussed here.
Something else I did was download a profile changing app. I got Quick Profiles, but anything should do. If anyone uses anything better, please share. I have a profile for power saving that turns down my brightness, and turns off wifi and Bluetooth. The app will let you put shortcuts on the home screen to instantly change the profile. I'd like to find one, however, that will also turn off gps and mobile data.
This is my battery stats for today's use. How is it? Thanks.

In order to get an accurate response, you'd need to post more screenshots from BBS - things like wakelocks, kernel wakelocks and app activity will help greatly to diagnose your phones battery consumption.
By the looks of the 1 screenshot that you have provided, I can only assume that you are a pretty heavy user...as the device did not have much deep sleep time (only 25%) and the battery per hour rate is 7.2% .

Yes I use my phone a lot during the day. Next time I will do a 100% to 1% and post more shots.
I updated my op with more information. How is it now?
Anyone.

Looks decent to me. Not bad at all for such heavy use
BBS Review
Here is my dump. How is my usage? Is 12.5 hrs till 4 percent good or bad? Note that the awake time is higher because I was listening to music with the screen off. Don't refer me to the BBS thread because my idle battery life is great. Thanks again!

You need to actually read the BBS thread..
If your idle battery life is "great" then it boils down to how you are using your phone. Are you letting it sleep or are you using it a lot?
Getting rid of GoChat will improve your battery life as it is creating a wakelock.
You will gain still more battery life by going into Settings->Sound and unchecking all the boxes towards the bottom. This is yet another known issue..
Looks like you are using it a lot, and getting the battery life associated with a heavy user.
Do you have a more specific question? I'm not sure what you are looking for here really. The main thing you need to do is research this stuff so that you are familiar with it.

I read the BBS thread and have already posted an idle log there. I only posted a log instead of a screenshot cuz I was lazy and didn't feel like taking 5 screenshots. The time that the wakelock was on was the amount of time I used GoChat, meaning the screen was on as long as I was using it. I just wanted a yay or nay of my battery life. I usually play videos from youtube for a solid hour, browse the web intensively, take a couple of photos, use 3g, and send some texts, if that helps in putting a figure on my battery usage from the screen on time vs the deep sleep time, so thanks for answering my question.
