First off, I'd like to say that this will probably be ridden with some very basic knowledge and understanding, as I am entirely new to the scene here at XDA & android mods alike. I purchased a Galaxy S4 back in March of this year and was extremely happy with it, up until the 4.4.2 update, which proceeded to turn my 24-26 hour battery life and turn it into 6 hours of heavy use and 12 of moderate to light usage. This life was a result of having 15% brightness, all smart features turned off, greenify, battery doctor, clean master, gps off, bluetooth off, etc. It was basically running as "bare bones" as possible. Seeing as this new life was unfit no matter what I did, sending it in under warranty to Samsung proved to be useless. Taking matters into my own hands, last night I successfully rooted and installed Hyperdrive 17.1 onto the device from this tutorial:
http://forum.xda-developers.com/showthread.php?t=2784138
So far this ROM and root have been incredible...but Im still looking to increase my battery life. As of writing this, ive had my phone on for 7 hours and am down to 67%. Are there any more options available (safe) to do to push the battery life back to being good or at least where it was pre 4.4.2, now that root has been established on the device?
JuiceDefender is the best app to extend battery hours. For example, when the screen goes to sleep, underclock the cpu. When wifi is on, turn off 4G and etc or turn off wifi when you leave your location (using mobile network to estimate your location).
For Greenify (purchased version), if you install Xposed Framework, you can disable apps like Facebook so it will only activate when notification is push to the phone.
BootManager (installed through Xposed Framework) - allows you to control what app is run on startup. Not much helpful here but if you reboot your phone often, it helps a bit.
LUX allows the phone to auto adjust the brightness further by allowing user to set a profile of brightness level.

Hi all!
I'm working on a cool University project here in Russia.
We have to make a mobile device that works for about a month without any charging.
Device should only wake up every day at 23:55 and send POST request to server to tell that "I'm doing science and I'm still alive.".
We've started with an Android device, ZTE racer and installed Cyanogen firmware.
We've made an application that:
enables AIRPLANE_MODE
asks AlarmManager to wake up at 23:55 every day
at 23:55 it disables AIRPLANE_MODE for a minute, aquires a wake lock for a minute
then sends "I'm doing science and I'm still alive." to server
and enables AIRPLANE_MODE again to save battery.
Right now we are getting 5-10 days of battery life.
I suppose that we could extremely increase battery life by:
removing some applications from firmware including "phone" and others
shutting down some services right in kernel sources. (In fact, we just need gprs and nothing else. We don't need Wifi, eccelerometer, GPS, ...)
decreasing CPU speed from application
I have couple of questions:
Is it theoretically possible to have 1 month of bettery life for an Android device? (I know that Kindle have more than 2 months of battery, so why we can't?)
Does anybody have an Android-based book reader? How long could it live in sleep mode and wifi turned off?
If device has no 3rdparty application installed, and it's sleeping in AIRPLANE_MODE... Who could possibly eat battery at that time?!!
Could you please give any kind of advice for our problem?
Thank you very much in advance!
I'd say yes it's possible to get that much battery life... Some suggestions from the top of my head:
Undervolt and/or underclock the processor (like you said), but do this from the kernel, rather than an application.
uninstall any unecessary system apps/turning off services (like you said)
Assuming your script/application is checking the system time of the phone to know when to wake, try having it just run an internal timer instead... I don't know how much battery life that would take, but I imagine that checking against its own timer would save battery vs requesting the time from the phone itself.
Assuming you haven't already, Try having so the display NEVER TURNS ON without physical input (i.e. pressing a button on the phone). The screen is a massive battery drain.
My Galaxy S3 Battery Life Sucks Please Help! 15% After Only 7 Hours.
I’ve been having this same problem sense I got my phone about 2 months ago but now I’m finally just tired of it! My phone is rooted, using the stock ROM.
What I do to help battery life:
- Every morning I hold the home button and kill multitasking and kill all running aps in the background then I open autokill which automatically kills running apps in the background that are not needed.
- I have power saving enabled
- Easy Battery Saver running
After 7 hours of use I’m already at 15% and through out the day I barley use my phone. Its like this just about everyday. I use my phone about an hour of the entire day of web surfing and Facebook usage etc. The rest of the day I’m only texting and maybe taking 3 or 4 phone calls that last 10 mins. How much battery could that possibly take? A flip phone can do that and last 3 days..
I used my iPhone 4S much more during the day then I do the galaxy S3 because the S3 has terrible battery life.
On my iPhone I would have about 22% after everyday of using it for 11 hours down time = sleep and 4 hours of usage = texting, , phone calls, web surfing, games etc.
I don’t play games or watch movies on my S3. Only texting, instagram, facebook, websurfing which is about an hour a day usage. Also a couple minutes of GPS usage on some days.
What can I do to fix this? I don’t want a bigger battery that will make my phone any thicker.
I have pictures below showing usage through out the day and usage under battery.
Please help!
Thanks!
You screen is using most of your battery. Check the brightness levels. Are they on max or close to it? Switch it to auto

Oh thats easy.
You're phone is always "Awake". It doesn't go into Deep sleep like everyone elses. If you take a look at the first picture you linked with the graph, it shows that the phone is always AWAKE.
For comparison, I have attached mine as a reference but something is DEFINITELY keeping your phone awake.

Can't really see anything that stands out per say...
If you see anything on that thread or any apps on your phone that you think could be keeping it awake, just uninstall them. I would suggest trying to remove them a few at a time just to narrow down which ones are keeping the phone awake.
Also, apparently this app helps a lot (https://play.google.com/store/apps/details?id=com.bvalosek.cpuspy) and Better Battery stats should give you a better idea of which apps use the CPU while your phone is trying to sleep.
Oh and remove any task managers you have installed.. Those tend to be the worst offenders.
One last thing, found this on another forum:
- Don't use an automatic task killer--not even the one that comes with the phone. Reboot your phone and look at what's running. If anything that you've installed is running and there's no reason for it, then uninstall it and find an alternative that behaves. Ignore any stock apps that run on boot as I've found them to be more or less benign.
- Weather widgets, live wallpapers, news/social feeds, any app or service that you use that runs--do without it if you can. If you can’t do without it, lengthen it’s refresh time.
- Don't use antivirus
- Set your WIFI sleep policy to never. The default is "turn off when screen turns off". This will cause the wifi to reconnect every time you open the phone. From any Home Screen select Menu/Settings/Wireless & Networks/ and then use the Menu button to see some new options - select Advanced. Then select Wifi Sleep Policy and set it to Never. Home key to return to Home Screen.
- If you have access to wifi, leave it toggled on as it is more efficient than 3G. Wifi consumes less battery power than 3G.
- I leave GPS toggled on too by the way. Apps use it as needed. When I'm done with Maps or an app that uses it, I'm sure to return to the home screen so GPS can stop. Under wireless settings turn on "Google location services" so that an app is able to use network resources to get your location instead of GPS. I have "VZW location services" turned off--don't know why that option is even there. By the way, I increase the speed of voice output > text to speech > speech rate because I like the directions to get spit out faster. That saves a bit of battery. Turning off the display and just listening for directions help. Also, often I just get the directions and then exit back to the home screen: GPS uses so much battery I try to get it over with ASAP.
- Under Accounts, click on any account listed and turn off sync for any items that you're not interested in syncing. For example, Google Books if you don't use it. Don't use Backup Assistant--I prefer syncing my contacts with Google. You don't need both. Also go into your contacts > menu > display options > backup assistant > UNCHECK. Also do contacts > menu > more > settings > contact storage > and select your Google account and "remember this choice"
Are you on the 3G network a lot or weak signal areas? Is your phone hot around the bottom? If yes to both, most likely it's because of the system attempting to find a better signal. When I was swapping out my SIMs, in various countries, I only have 3G network and my battery fully drains in 7hrs at idle. The only way i can go a whole day is to place my phone into airplane mode or wifi only to conserve the battery.
my battery runs at-most 13 hrs........................

Welcome to smartphones. The calls alone will drain the battery. Seven hours isn't horrible for all that. It isn't a flip phone.
why your phone is always awaking?

maybe you have to flash a new rom
If you want, you could try to flash a custom ROM. I had the same problem that you have, and I flashed Revolutionary S5, and now my phone lasts minimum two days with the same usage, maybe a bit more.
Too bad Tony Stark hasn't gotten involved

Titanium Backup will assist a little bit. When you do a backup of an apk it will tell you if the application is running. You can find all kinds of sneaky apps this way. Many of them were ones I didn't use and didn't really want. That will probably yield minimal results, though. Keeping a black background helps on my S3. Colors, widgets, and live backgrounds will drain the battery. Turn off the menu and back key lights. You know the buttons are there. Turn off all haptic feedback and key press sounds. Of course, try to lower the screen brightness. Leaving my data and sync on hasn't caused me any problems, but you will save some battery by turning them off when not in use. I also read a post about hidden menu options that ran even when they weren't meant to. That was an issue that destroyed battery life. Some ROMs also have settings for data connection type. You'll save power by telling your phone to not worry about gaining signals like 4g, 3g, etc. As other people have said, try out some ROMs that make battery life a big priority.
it CAN get better
if you want to have a good battery life, use custom rom and kernel (or a modified stock like omega rom), watch out for wakelocks + apply these settings:

I love Android.
I think the customization is great, and since v4 it's smoother and feels more responsive.
There are LOTS of apps and it's better than iOS.
But i'm sick of the battery issues.
I've always loved trying new features, ROMs, apps, hacks and whatever.
I now have SGS3 and it's my third android device, and i've installed ROMs dozens of times, even on my friends' devices.
One thing that always kept me alert is the battery life - the maximum I can get from my battery is around 30 hours with my usage - 1/5-2 hours of screen, ~45 minutes talk, lots of standby.
But every now and then, my girlfriend, my dad, my aunt or my friend ask me 'why does my battery drain so fast?'
Sometimes its google maps.
Sometimes its mediaserver/media scanner
Sometimes - and only I can see it cause they are not familiar with tools like BBS, it's gsf (Google Services Framework).
The point is, when you have an Android device, you need to check the battery stats every now and then to make sure nothing is unusually heavy on the battery.
I am currently experimenting with ParanoidAndroid and AOKP, which are faster and more responsive than omega/stock.
Yesterday i went to sleep (6 hours) with 25% battery (after it lasted 15 hours) and I turned off the data connection and the wireless connection.
I woke up after 6 hours (lucky..) and I saw my phone if off. after I connected it to the charger and turned it on I saw mediaserver decided to wake up in the middle of the night, after It almost did nothing during the day, and worked for 5.5 hours until the battery died!
Today I unplugged my phone and in 1 hour of standby 10% of the battery were gone, I checked what happened using BBS and saw gsf again (that GTALK_SYNC whatever wakelock) was draining battery, after I thought I fixed it yesterday when I disabled app data and browser sync in the google account sync options). I rebooted and now it seems ok again, the phone is back to ~70-80-% sleep.
I want to emphasize that I don't like all the stupid battery tips that tell me to castrate my phone:
turn off wifi when it's not needed, turn down the brightness, lower the screen timeout, disable sync (wtf? but its a smart phone, I WANT push notifications!) and that sort of things.
I KNOW I can get >24hours of battery without disabling the basic features of my phone.
And the draining battery processes that I mentioned earlier can suddenly appear even in a stock ROM, so I don't think it's PA or AOKP's fault.
What I want is that google will finally build a supervisor entity that will check what causes an unusual battery drain, check if it makes sense, and disable that cause!
It's absurd that google maps application comes with default 'enable location reporting' that constantly drains your battery and for what?? google maps doesn't run in the foreground, why the hell will I want that background location reporting draining my battery? and if so, why do you put this option enabled BY DEFAULT? The average user doesn't know this sort of stuff, and get only 10 hours of battery out of a device that should ideally provide ~30 hours!!!
Just wanted to let it out of my system...
And to get useful battery tips if any...
Hello,

There are quite a few threads on this already including what I wrote (pasted below).
<<<<
I had two types of standby battery drain - mobile data and wifi. I have fixed both of them through lots of trial and error. From my testing and looking on XDA at similar experiences of people on other phones, these are bugs in Android rather than anything Elephone can fix through updates (I'm on the latest 20160419 update).
I fixed the mobile data problem by creating Tasker profiles to keep the phone on 2G whilst it's connected to wifi. I can't post links yet but a search on XDA/Google will find you these profiles. Maintaining a 4G connection is unnecessary whilst on wifi, besides, some people have problems receiving calls on this phone whilst on 4G. If the phone is not connected to wifi (rare in London because it's everywhere even on public transport) 4G comes on. Best of both worlds.
The wifi drain solution sounds counterintuitive but it is simply to set it to 'always on'. With both of these measures, my standby drain has been 1% overnight for the last two nights and roughly 0.25%/hour during the day. Standby drain on 4G whilst moving around London with location on at least quadruples battery drain to around 1-2%/hour.
Some of my other settings will have an impact too. I find the auto-brightness calibration of the P9000 poor, so adjust brightness manually (which also saves battery life). NFC, bluetooth, etc. I only turn on when needed. I use Greenify and have all apps Greenified except Tasker, Textra, and Hangouts. I haven't Greenified any system apps except Google Maps. Location is always on but mostly device only (again counterintuitive, you'd expect it to be 'battery saving') unless I am moving around in which case I have a Tasker profile to automatically switch it to 'high accuracy'.
I tried to get Xposed working so that I could use Amplify too (see my other post) but that didn't work. Since I'm very happy with battery life now that's not that important anymore though it would be nice for the further tweaks it makes possible.
There are too many other variables to list and everybody's phone is set up differently. However, hopefully using some of the main big gains I've listed above you can fix your wifi drain specifically and improve standby drain generally.
Well, it's somewhat problably what keeps the phone awake, this occurs after factory reset, i already did the Tricks you've listed and on screen Features and so on are all off, there are no Apps who should keep the phone awake Cause it's happening Straight after factory reset so there are no other Apps..
Push
Finger print sensor or DT2W for sure. Disable them
On the latest ROMs it is the finger print sensor. Turn it off or go back to 20160810
I have googled the heck out of this and haven't found a fix. Please help!
I have a NON-rooted Samsung Galaxy A6 using T-Mobile US. This is the phone I use for work and it has KNOX running on it (ick), so I can't root it or re-flash it.
Just last week T-Mobile sent out the update to go from Android Pie to Android Q. Every since then my LOCKED Recent Apps keep getting closed overnight.
I have turned off everything in Device care: Auto optimization, Auto restart, Optimize settings... All are off. I have also turned off Adaptive battery and Put apps to sleep and added the apps to Apps that won't be put to sleep and removed then from the Optimize battery special permissions under Settings > Apps.
And I've rebooted the phone.
With all of this, it still closes my locked Recent Apps.
It didn't do this under Android Pie.
My apps continuing to run and not getting killed is 1,000 times more important to me than battery life. I have a charger at my desk, one on my nightstand, one at the office, and one in the car. The battery just has to last long enough for me to get from one charger to another. I REALLY wish Samsung/Google had a setting to just turn all thud battery optimization BS off for those who need performance over battery life. *End of rant.*
