Hello,
Below is the message i wrote on the google support forum, but i havnt gotten a single reply yet, so i turn to you guys, in hope that you're able to help me
I have been experiencing this issue on and off for the past month or two. The issue being, that something called "Android OS", in the battery usage list, is eating up all my battery.
An example is, currently my phone has been unplugged for 1h30m(im down to 69% battery life remaining after i unplugged it at fully charged 100%) where the battery usage is ranked as follows:
Android OS: 72%
Display:18%
Wi-Fi: 2%
Cell standby 2%
Android System 2%
and so on and so forth.
The reason why i wrote (kernel) in the title of this question, is, that with the app "Powertutor" i have been shown that the main "app" or proccess eating up my battery, when this "Android OS" is eating up my battery as shown in the Battery Usage list, is the Kernel. Right now is shows the kernel is using 84,3% of the energy usage, Handscent has been using 3.1% and so on.
Often a reboot will bring the phone back to normal and the Android OS issue goes away for a while. A friend of mine, however, who has the exact same phone as I, has this issue, almost all the time, and a mere reboot doesnt seem to do the trick for him. His phone only lasts 6-7 hours tops, where it most of the time is just idle, and he isnt using the phone at all. While mine, when the Android OS issue isnt present, last up to 20 hours on a single charge, when i dont use it much.
When the Android OS process is eating up all the power, the phone grows really hot as well, and the difference is easilly felt. So when i feel that my phone is hot like that, i automaticly think "oh, time for a reboot".
I've been unable to find any info regarding this issue on the internet, and therefore I'm unsure what to do to fix it for real. Tried several factory setting resets on my friends phone, tried not installing many new apps, formatting the SD card, formatting the phone from bootloader (still testing his phone to see if this worked properly)things like that, but always, the issue returned, as on my phone where it only pops up once every other day.
Hopefully, someone will be able to help, or shred some light on the case.
Thank you,
Chris

Having Exchange sync on, by any chance? Try turning it off for a day, see if it helps.

"Exchange sync" being exactly what? The basic sync function on the phone that can be enables and disabled? The basic sync with your google account?
If thats the case, then yea im having that on all the time, so that it may sync whenever it wants to. The sync icon doesnt appear that often though, so cant see how this could be the reason why. But if you come back to me and tell me that this is what you meant, i will definetly give it a try
Thx for responding
No, Exchange sync means - MS Exchange account (in addition to your default Google account) that syncs calendar/email/both with Exchange server.
I'm guessing again that that is something extra you must install / set up, which i have not done. The only two accounts i have that can sync are my facebook and my default google account. I never sync the facebook one though.
Edit:
Update:
Reinstalled Watchdog Lite today, since my phone has been exceptionally sluggish, and SeePU graph keeps showing a full graph on cpu usage. I've had to reboot it twice today, in hopes of it returning to normal state. It does for a while, but then returns to a slow state where Android OS uses like 80% of the battery.
I made Watchdog Lite monitor the base android processes as well, and right now it keeps warning me that the "Base System", "Linux Process" uses up 89,6% of the CPU and 10,3MB of RAM, while nr 2 on the list is Android System, Foreground, with 3,8% and 27 MB.
I feel like the state of my phone is worsening, and I'll prolly do a full factory reset(again)/format of everything within a few days if i cant find the root of the issue this time around.
Please help I love my phone and i want it to be healthy again.

"OS" is an abbreviation for "Operating System". That means ALL of the background stuff that eats battery and CPU time that isn't attributable to a process or function easily understood by the typical user. This includes, yes, the Linux kernel, but also all the other background things that your phone does in order to continue functioning in a normal synchronized state...
Your phone has a CPU. The kernel has a process scheduler, which swaps different programs in and out of the CPU in order to make it look like it is running more than one thing at a time. Each clock cycle consumes some amount of the power from the battery, so if it assigns 10 cycles to process A, 10 cycles to process B, and then waits for 20 cycles for I/O synchronization, then HALF of the power consumed in those last 40 cycles (attributable to CPU) will be "Android OS". Clear?

Alright, I was wondering exactly what it meant when it just said Android OS, just that seemed like quite a broad description.
But what your saying is that it may be other applications that is actually eating up the power, just the kernel assigning the power to the program, and therefore the Battery Usage shows the kernel/Android OS as the culprit?
If its the case that its an app then, that through the kernel is triggering the usage that drains my phone, then how come my friend had this issues with an almost "naked" phone? He had installed just a few apps and still ran into this issue.
Am i understanding what you're telling me correctly?

It's not normal, something is causing it. Most likely some poorly written app or some other weird thing is causing the "Android OS" (which I assume is likely the virtual machine itself) to do bad things.

Today the linux process "init" has been hogging up all my phones resources, as in 77%+ of all the CPU usage :/
Was wondering if rooting my phone and installing/ flashing some custom rom would solve the issue for sure? Or should I send the phone back to the states for at checkup or repair? (dont think this is needed but now I ask anyway)
Is there an app that could track down exactly what is sucking my phone dry? Cus all that I've found are those broad references or processes :/
Thx for all your responses

There is no solution, because you can't track the app that is causing the system to hang.
You can uninstall all the latest installed/updated apps and install them one by one, using Titanium - and that'll pinpoint the offender.
Hi,
I have a big problem with my nexus one phone. The battery life of my phone is very bad (only 12 hours, with NO (app) USE! (only text messaging!))
I think the problem is that when I check "Battery Use", the "Android OS" is getting 70% (and more, up to 93%!) of my battery use...
What can I do? I've seen other topics with this problem, but there is always a special app that's the problem. I've reseted my phone several times, so no new apps installed, and I still have the problem...
But sometimes, "Android OS" isn't running in the Battery Use, only the "Android System"... But once Android OS has started, it climbs up to 70-80-90%... Help?
Thanks!

It's clearly some program you have installed, start killing stuff or removing stuff one by one to see what it is.
All else fails, factory reset and start over.
Thanks for your answer,
but I've tried all of this, I have already done a factory reset (already 2 times!), but the problem stayed... Are there any know problems with android 2.2.1 running on a nexus one? Could flashing another rom solve the problem?
Hello,
Since updating my Sony Xperia T (UK unbranded phone) to Android 4.3, I have noticed a significant decrease in my battery life.
I have already re installed the software (version 9.2.A.1.199) when it was released in April twice due to various problems after updating.
Please can someone tell me if these stats are typical?
My 'Screen' time when I took this screenshot was only 17 minutes - I pretty much hadn't used the phone today.
I have also been at work all day where I have full signal.
I have pretty much uninstalled every app on my phone, except Facebook.
Many thanks
Katie
It seems not to be ok. Reset your phone by holding power and volume up button together. Use your phone normally, battery needs time to settle after few cycles.
Edit: Didn't see that Google Play Services drain so much battery, uninstall updates of it and update it again, and it should work then.
4.3 is a software designed to let interested 3. parties know any minute what are you doing and where you are, much more than it was under 4.12.
Enable Stamina mode. Install a program that provides the capability to select startup items. Manage location reporting to the minimum required. Install Greenify, and then sleep apps that you don't use that much, or resources monsters like Facebook when not needed. Install an older version of Google Play Services.
Wasn't .199 the first version of 4.3?
Hi,
I know there are many topics on the subject but I didn't find any solution to my problem.
So, since a couple weeks, about when I moved from Europe to the US, my phone drains significantly more battery than before. This has apparently nothing to do with screen brightness, wifi or cell data, since it occurs even in airplane mode during the night. I used to lose about 1-2% during a night, but now it's at least 15%.
You can find a couple screenshots from BetterBatteryStats there (sorry for broken link, it does not work otherwise): n.ethz.ch/~bauera/uploads/Screenshots/
So as I noticed, there are a couple wakelocks but nothing that could explain this large drain. Any idea what could be the reason and how to fix it?
FYI I am using the stock rom 23.4.A.1.232 with Android 5.1.1. Phone model is D5803. The OS was rooted directly when I got the phone in October 2015 and as I said, I did not have any battery problems until recently.
Thanks for your help!
Alex
that's the lollipop battery drain bug on mobile radio, marshmallow should have fix this
Thank you for your reply. However are you sure of that? The bug you are mentioning is apparently linked with mobile data, which I haven't even turned on since a couple reboots at least. Moreover, the battery stats for the night (from the built-in battery menu) show that the mobile network was fully off during that time (airplane mode).

I found this fix worked for me
Thanks for the suggestion! Unfortunately it didn't work in my case, I still lose about 2%/h in airplane mode and screen off.

BBS - Better Battery Stats is your freind. There's also lots of tips in the thread on how to limit most of the common wakelocks.
There are several services in the new Play Services that are keeping your phone awake. With the introduction of wearable bluetooth there are new fitness services that are looking for your wearable devices constantly, disable them and your battery gets better. Obviously if you use fitness bands/trackers then this fix is not for you.
If you have a rooted phone download Disableservice from the playstore, it's a lot easier to use than Xprivacy and you don't need to install Xposed.
Once it's installed, open the system tab, open Google Play Services, then untick (disable) the following:
ConfigFetchService
FitnessSyncAdapterService
GoogleLocationManagerService
GoogleLocationService
NetworkLocationService
ProximitySettingInjectorService
UserPresenceService
WearableControlService
WearableService
WearableSyncService
then reboot your phone.
Disabling these from running should have no impact on your phone, it doesn't for me, and will give you 10-15% more battery life.

Solved Battery drain for Me
I was also suffering from the same battery drain issue, but after doing a lot of research on this forum, few tricks mentioned here worked for me.
It had been 6 days I bought the phone, so was very disappointed by battery life, did upgrade from PC to Lollipop, but still the problem persisted and even worse. So I decided to go back to Kitkat and followed steps here: http://forum.xda-developers.com/z3-c...d5833-t2906706
After downgrade the battery got somewhat better not satisfactory, so I followed the trick of complete drain upto 0% and charge to 100% (switchded off) after reading posts: http://forum.xda-developers.com/z3-c...5#post59797105 by Sydr08 #182
and cache clearing trick after 0% to 100% charge http://forum.xda-developers.com/z3-c...harge-t3207737
After doing 100% charge I turned ON with vol+ pressed but phone did not respond (I guessed that it didn't worked, so switched ON normally) but after booting I found few settings to be reset so I guess it worked
So finally this trick seems to work for me, now the drain has slowed down to a lot extent. I have used phone regularly (calls, games, whatsapp, Music etc), the battery has dropped to 76% in around 8 hrs ( without stamina mode ) just expecting it to last for two days, and more than that with satmina mode.
Firmware: .77 (India)
Model: D5833
Hi Aakm,
As you said, the tricks mentioned so far on this thread were not really effective, at least for me as well. I could live with that 25-30% left at the end of the day (it is still much better than my old Samsung GS2), but I would be glad to be back to the 2-3 days of moderate use as I had during my first months of ownership.
So I'll try this out over the next days and hopefully it will work, thanks for suggesting! It sounds a bit like magic to me but let's give it a try
Best regards,
Alex
Unfortunately the full drain+charge did not change anything for me. I did not try to downgrade to Kitkat but as I've had good battery on Lollipop for several months, I doubt it would help.
Anyway thanks for your help, but I guess I'll simply wait until Android M comes out and take the opportunity for a full factory reset, hoping it will solve the issue.
Please guys mark the star on the bug report, the more people agree, higher will be the chance that google decide that it's time to fix it

Hello everyone!
I recently bought the Samsung A33 5G, but I'm having battery problems and I don't know what it could be.
Using, for example, WhatsApp or Twitter I spend approximately 3% every 5 minutes using Wifi and with the brightness at 20%.
I have monitored the battery with apps like Battery Guru and AccuBattery but I have not seen anything strange. I have also tried to wipe the cache partition from the recovery and repair the apps but it has not improved either. I've also disabled battery optimization (seen it on reddit and some have found it helpful) but it still doesn't get any better. I replaced the phone but the problem persists.
Somebody can help me?
Thank you!
Battery consumption is strongly dependent on the size and type of screen, services used, distance from the GSM mast. There is a long way to go to get your phone to use less battery. For starters, try using a Wi-Fi connection for a while, without using GSM. The next step is to turn off LTE/5G and stay on a slow but less draining 2G/3G battery.
By the way, disable unnecessary services with Debloat Tool, mainly updates and sending notifications by applications that you do not need.
