Android OS/Battery use across various roms.

Hi people,
First post here I think, but Ive been around a while.
for the last few weeks ive been having terrible battery life on my Nexus S (i9020) and the battery stats are showing "Android OS" as being the culprit. I have tried loads of different things like a full wipe, remove all my apps etc etc.
I installed the ICS Rom, the Kellmsking MIUI rom and a stock 2.3.6 rom all with the same problem.
Each time i install a new rom, I do a factory reset/wipe, wipe cache, dalvic whatever thingy etc yet i still get the battery issue when I install a few rom.
Anyone got any idea's on what i can do to sort this out?
Ive searched and searched, both here and everywhere else on the net and I cant find any useful information.
Thanks in advance guys.

Did you try wiping battery stats in Advanced menu in CWM?
Also next time you install a ROM go to mounts and storage and format system partition.

i had the same battery issue til i flashed the matrix rom with the matrix 10.0 kernal...they calibrated the battery with a calibration app...since then i get a good 12 to 18 hrs on a charge..i have the governor set to smartass..1000/200 with deep idle enabled...give it a try it worked for me

Matr1x kernel also does the trick for me... you could also try the teuv! But matr1x is the [email protected]#t for me! SmartassV2

Thanks guys, I'll look into those suggestions.
Yup, I wiped battery stats and system etc. pretty much everything that has an option to be wiped, i tried and still have the problem.
I just cant get my head around why its happening though. I've had the phone since march and its been fine all along.

I would try changing battery. Maybe your battery's life just ended...

but that doesn't explain why "android OS" is giving so much trouble in the battery stats.
I didnt seem to have it after flashing ICS but i had to get rid of that for other reasons (unreliability, crashing rebooting etc).

just downloaded the matrix kernel and am about to flash it.
My phone has been in airplane mode for the last 2 hours or so and i had reset the battery stats just before then. its showing 46% on "Android OS" in the battery stats and only 18% in "Display".
I also have Sync'ing turned off, GPS turned off, bluetooth off etc and no apps installed, yet i still get the battery drain.
Hopefully this kernel does the trick.

Well, what you described makes sense though. Assuming you weren't playing with the phone hardly at all, during that period of time, the OS probably used more power than your display.

heres my battery stats after 12hrs over moderate use...mostly texting at work..n some net

thanks guys.
I installed the matrix kernel last night and its early yet but i think i still have the same problems. the phone was actually off this morning (bout an hour ago) and I had left it only 6 hours previously with 3/4 full so it ran itself dead overnight in standby with not being used.
Im getting really tired of it now, Have tried everything from kernels to roms, removing every app i use etc etc and still im having this problem.

sup people, Little update with some pics of my system. I cant seem to do screen shots on this phone like I do with the Galaxy S so their just photos.
As you can see, in the last 10 hours and 15 mins, Android OS has used 25% of the battery. it was originally higher than the screen usage but i turned the brightness all the way up to see what would happen with the stats.
Its been out of the charger since about 12 O'Clock(4 and a half hours ago) and my battery level is at 37%.
You can see in this one, I installed the Matrix kernel last night and reinstalled 2.3.6 stock rom (rooted).
Any tips or advice is very much welcome guys. Its either that or im gonna end up taking it outside and shooting it.

Well, I went ahead and tried yet another rom. I went with this Oxygen rom from the dev section,
http://forum.xda-developers.com/showthread.php?t=1285243
At this moment my battery is at 80% and I have added nothing, not even signed in with my gmail account. Im gonna give it a while and see if it drains excessively again and see if that could help pinpoint the problem.
the kernel has obviously been replaced too, with the one that comes in the Oxygen rom.

When is OTA due?

I'm not quite sure what you mean?

Well its been on for 8 hours now and theres 31% left in the battery. This is with literally no usage in that time.
I'm starting to come around to the thought that the phone itself is faulty so i think ill look into reverting to stock rom, stock recovery, lock bootloader etc and take it to the shop. Anyone got any advice on doing that?

Download Better Battery Stats from the market and look at partial wakelocks to see what is draining the battery and kill it

sorry mate its wakelock detector

I am suffering the same problem, and it drives me nuts
not a user of music, video or things like that
for me the troubles started with the last update from 20 November
without using the phone, the battey drains in 9 hours, not installed any third party apps
Android OS kernel 52% , Android system 9,8 % Media 5 %
I contacted samsung for a couple of times, and only give the basic answers
already wiped cache, several times, re installed the stock firmare two times, MJ7, nothing helps
i am getting really sick of this and already looking around for another phone
Kind regards, Wiebe

Have you tried to stop comm/sync stuff? For instance disable the sync toggle? Or both Wifi and Mobile Data when you do not use that?
Have you tried wakelock detector to see what keeps your CPU from entering deep sleep state?

What eventually fixed mine was a complete wipe, then reinstalling stock. (I have since gone on to a custom rom again and custom kernel) - my Android OS/System sit on 3-6% average now. Where as previously they were sky high.

IT IS A KNOWN ISSUE!
This thread will help you optimize ur battery - http://forum.xda-developers.com/showthread.php?t=2579075

Don't confuse the percentage in settings for the actual drain percentage. It just means that of the ACTUAL drain, 20% is done by OS. So 20% of for example 4% per hour.
Use BetterBatteryStats and Wakelock Detector (both can be found in XDA) to find out what is really causing it.
My Android OS and Android System are also both at 20%... But I still only lose 0.1% in deep sleep.
And in the past hour it went from 96 to 93%, with screen at 100% brightness, Wifi, tapatalk and music. So....

Again.... It's a known issue. There are many Threads about AndroidOS Bug and the Deepsleep Problem.
Just search for it or read the last few days in this forum.
Every day a new Headline for the same Problem and in 95% of all no App is the Problem for the battery draining.
If you use your Phone not often, and your Battery lose 2-4% per hour, AndroidOS is on top of your Battery Status list and everything is fine.
If your Battery need much much more per hour, and AndroidOS is also on Top check the wake time from Display and AndroidOS.
This is okay

Putting the 2-day battery life claim to the test

I'm usually a fairly heavy user, but this week I haven't been quite as hard on the Z5C as I normally am, and I saw it as a chance to test the 2-day battery claims.
Everything was left turned on as per usual - Wifi, Bluetooth, LTE and the like were left on for the most part. Screen was on auto-brightness, all the usual stuff. I didn't try to 'milk' it for more. I didn't use any of the battery life extending modes.
52 hours and 26 minutes later, with 4 hours and 26 minutes of screen-on time, I was at 2%. I'd definitely call that a pass.

that's amazing.. im experiencing 9 hours of battery life with 10 mins screen on time, trying to figure out how to fix wake lock with sonys tasks app and some calendar storage app but seem to be completely unsuccessfull in this... you think if i do a factory reset of the device that'll fix it?

Mine is changed out now because of faulty lens but I've used it for a few days and I got same usage as OP.
you might want to perform a full factory reset and if it doesn't solve your problem return it to Sony for warranty.
Also, do not close the recent apps constantly. Let them run in background will improve the way lollipop (and soon marshmallow) runs.

thanks i've just done a factory reset and unfortunately still same two processes are holding up hundreds of wakelocks on my devices not sure how to further troubleshoot / fix this..
processes are :
com.android.providers.calendar
com.sonymobile.tasks
does anyone know what those processes do and how i can go about just removing them or replacing with something not buggy? will be leaving for an overseas trip in a weeks time (away for a whole month) and this new phone which i got especially for it (good camera and waterproof) will be completely useless to me if the battery keeps failing on me. love the phone so far but this battery issue is killing my transition experience
had full charge at 9am and now at 4pm already at 33% battery life

for testing purposes.. do you have a calendar app? can you disable it? or clear the cache from settings >apps...There is some rogue app that is constantly accessing storage.. I've had it happen on my old phone with custom ROM.. also do you have exchange/gmail sync try changing that

for battery problems you can use Wakelock Detector without root (following the guide in the google play page https://www.google.com/url?q=https:...A&sa=D&usg=AFQjCNFCL0Z8eiWrc0xTYvz2hQAgPd3xoA ) and, if you find system apps that can't be disabled manually, you can use Debloater (windows application) http://forum.xda-developers.com/android/software/debloater-remove-carrier-bloat-t2998294 which can Hide ( pm hide command) the system apps. I don't know exactly what the command does but i hid three system packages and they disappeared from the running processes list: either they are completely hidden from the system or they are stopped and not running. For example, i hid the Software firmware upgrade app and its settings in Phone Info disappeared along with the Software upgrade notification in status bar.

My battery life was fine until I recently updated to latest fw version using Flashtool. I can't update the phone with PC Companion anymore. I'm a heavy user, I play games, watch videos, check social networks, listen to music, download apps etc. But before using flashtool battery can last me a day or so. I don't think it could last more than a day if I don't use it. At night, for example, sometimes I let the phone idle, even with stamina mode on, the phone drains 1% per hour. I don't think that's good. I hope with the marshmellow update battery can improve.

do you set up your phone after a factory reset?
U should try this: factory reset, not completely set up phone, only necessary apps like WhatsApp, Google account etc, maybe disable or remove the unneeded apps and then keep using the phone for 2 - 3 charge cycles. Then all should be good. If not, return the phone. If all is good by then, u know it's not fault of firmware or phone but fault of some app u installed.

Did u flash userdata.sin (factory reset)?
I really can't believe some people having this bad battery life.
It must be some bad app or something, I think..
The only way to test is full factory reset including wipe internal SD and then test the phone without fully setting everything up (installing apps etc)

I think I'll do a factory reset. But maybe when the marshmellow update comes, I don't want to have to set everything up again. Btw if I want to update phone flashing a new fw via flashtool is it recommended to do a factory reset before or after updating? Thanks

Mine has only maybe 30ish % left in the evening after one day with some youtube on the bus to and from work and random email and IM check ( 3-4 hours screen on total). Maybe it's youtube taking away all my battery...
I suspect it can only last until noon the next day maximum if I do my normal use and don't push it on power saving.... I don't know if I can call it a pass.. I guess it's somewhere between a pass and fail to me..
but, I do notice that it drained very fast in the first few days when I bought the device. After using it for a week it's a lot better. So if anyone is wondering why the battery life on your new device is really bad, try use it for a few days.

If you're reading this, you're probably regretting taking the latest OTA update.
It seems that Google hasn't been so kind to our batteries this time around, and with no root is in sight (thanks AT&T), our likelihood of any real battery life improvements is severely limited. Here are a few tips which may help remediate the situation.
Don't drop the soap...
Suggestion 1.) Reset app preferences. This may help to sort out some battery draining bugs:
Navigate to Settings>General>Apps>(dropdown)>Reset app preferences
Suggestion 2.) Disable all AT&T & LG bloatware. Less apps to run = less potential battery drain:
Navigate to Settings>General>Apps> disable everything you don't need
Suggestion 3.) Force GPU rendering. This will take some load off of the CPU which is more power-hungry than the GPU:
Navigate to Settings>General>Developer Options>Force GPU Rendreing>On
Suggestion 4.) Disable battery optimizations for all Bluetooth-related entries, Nougat is known to play nasty with Bluetooth:
Navigate to Settings>General>Battery & Power Saving>Usage>Ignore Optimizations
Suggestion 5.) Turn off IZAT low power location estimation. Contrary to it's description - this will actually actively use Wi-Fi for location services when your GPS is off. This feature is a no-go for battery life:
Navigate to Settings>General>Location>Low power location estimation>Off
Suggestion 6.) Disable Wi-Fi when screen is off, this will mitigate network drain while your phone is idle:
Navigate to Settings>Networks>Wi-Fi>(dropdown)>Advanced Wi-Fi>Keep Wi-Fi on when screen is off>No
Suggestion 7.) Disable Enhanced LTE services. You will lose HD call audio, however this feature is known to cause excessive battery usage on the AT&T network:
Navigate to Settings>Networks>More>Enhanced LTE Services>Off
Suggestion 8.) Install Greenify and Greenify pretty much everything, including system apps. Make sure you connect the phone to your PC, enable USB debugging and run the ADB commands to enable aggressive doze. It is still far better than Nougat's built-in doze.
Suggestion 9.) Pray. Jesus may not save your battery, but doing anything rather than using your phone may help the battery last longer... :angel:

Or just do a factory reset and solve a lot of the issues. I don't have the battery drain I always do a factory reset after an OTA for 2 reasons 1 it's recommended 2 it solves the optimization of apps because when changing operating systems it doesn't do a smooth transition and usually leaves behind some of the old system cache that can only be removed by factory reset

Not everyone wants to do a factory reset. It can be a big pain losing data and restoring all your apps one by one. If course this wouldn't be a problem at all if we had root, because we could use a custom recovery and clear the system cache manually.

Yup, I've pretty much figured out this phone. Carrier models (especially AT&T's) really suck because of background apps you can't disable without root (which is also likely impossible unless they'd release a .TOT/ .KDZ to be examined for root possibility). Additional installed apps drain the battery to varying degrees, especially with Nougat. Compounding everything, this phone's battery life is anywhere from 2/3 to 1/2 as efficient while using mobile data/ especially with a low mobile signal. Factory resets do nothing to fix these problems. Hopefully 7.1.2 or 8.0 will eventually be signed and distributed for us, otherwise this phone seems like a lost cause.

Strange thing it's it now works. I pretty much uninstalled everything. Then I slowly reinstalled the things I wanted slowly, over weeks. Even android wear. But there are things that still will crush the battery life. Either way it seems normal now.

I am awaiting my g6 and was curious to know the battery life , came from real life review battery standby drain on g6 to here via link. This made me lol . Thanks for the other suggestions as well , will try them out.

Thank you for this! Ever since getting this phone (Just over a year ago), the ONE THING that has bugged me is the immediate and apparent horrible battery life! I went through this and did as much as I could, and noticed an immediate improvement. Also has helped with the heat, it would get a worrying level of hot. One thing I wasn't able to figure out was this, as I couldn't find it where you indicated in settings.

You need to activate the Developer Options. To do that simply navigate to (assuming to are on G5 LG-H820, Android v.7):
Settings>General>About Phone>Software info
Now start tapping on "Build number" till you get the message "You are now a developer".
Developer Options will appear in:
Settings>General>Developer Options

Huge battery consumption, help needed

Hi all,
I am very satisfied with my device except for the battery life. I always had like 3-4 hours SOT. I was not happy but it was OK.
Lately I started charging the device every day after work (I would come home with dead phone after only 8-9 hours of it being unplugged).
So I thought the battery is defective, I must change it... and I did change it yesterday. The thing is that even the new battery behaves almost the same. It approved somewhat and now I will return home with 10% battery instead of dead phone 1 hour ago. But still the battery is terrible...
Can anyone help me, share some advice on how to improve it? I have disabled many software (even facebook), disabled location... did everything I could think of.
I am thinking some app is drawing the juice but cannot put my finger on any of them.
Some screenshots are attached that might help with your tips/advices.
Thanks!

Are you rooted? On nougat? If so get background restrictor APK here on XDA and kill background apps and tasks so they can't run if you do not open them. Lower screen brightness. Install kernel auditor and shut off cores 4 and 8.

uninstall chrome. Then try accubattery (better bcause after android 7, they join all in android system to mask each app consumption. If after this you still can't find out where's the problem, start the phone in "safe mode". Even the consumption is better in this mode you must do a full wipe in recovery mode (vol up+power+home) and after this, reinstall one app each time and see after reinstall the second one and so on until you find out in which app is draining the battery
If you want you can starting by disabling background data in settings but I think isn't the clearer way to find out

This is going to surprise you.
I've had this phone for years and I've tried everything - and the BEST result is when you DON'T DO ANYTHING except disable Facebook and Instagram, and any Google Apps you don't use.
Do not tamper with anything else.
I figure that Samsung tunes this phone so tightly that if you leave it alone it operates as it should.
Anytime I disabled anything else, battery life suddenly and drastically reduced.
The phones runtime software kicks in and if you have disabled something it checks routinely, it will keep the phone awake constantly looking for a ping back from that process.
I just went through the whole process again meticulously, App by App.
Also DO NOT enhanced messaging OR the device antivirus. If you have, you must reset and then train yourself not to engage these too regardless of how hard The phone tries to persuade you!
Then - the battery life becomes like a normal phone which means you'll still need to charge everyday but it will take you through a full heavy day... And this is fantastic!
Honestly try it and you'll see what I mean. The S6 edge plus is so finely tuned, anything you block will start a feedback loop.

I had similiar problems , the way i fixed it, i disabled/uninstalled all samsung applications what i dont use, i disabled/uninstalled all google applications what i dont use. Cold weather (like -20C) will affect the battery life too.
Disable / uninstall apps you dont need. That helped me a lot and got even more battery life while at stock nougat rom with all updates installed.
try wiping cache from recovery and reboot your phone.
I hope this helps you
