Huge Android System/Android OS battery drain. - Galaxy S 5 Q&A, Help & Troubleshooting

Hello,
First of all, I know there are already 5000 posts about this, but none have any working solution for me.
I even bought a new battery thinking it was its fault, but I still get 2hours+/- OST.
I already tried to reset, and for a while, very short while, it worked, I managed it to drain only 2 percent in like 15 minutes, while phone was downloading updates and I was playing clash of clans. (Screens below) (So the new battery can't be faulty, I think).
Then, after 15 minutes I started looking into the phone, using chrome and other apps and then battery started draining like crazy, something like 1.5% per minute.
Screens made at 18:00 are latest ones, after a new reflash with odin.
I have no SDcard in the phone, no known unwanted apps (only app I have installed that is not from the play store is spotify, because is not officialy available in my country) I have no antivirus/cleaner apps.
What could it be? How I could find the exact app which is draining the battery in the Android System/OS processes?
Thanks.
Screens explanation: As you can see in the first two, in the time interval of 10:35 -> 10:50 the battery drain was 2%, and from notifications you can see it was downloading updates, apart I ve been playing the whole time, from 35 to 50, that game.
3-4, Battery 25% at 11:15, ONE minute later, at 11:16 battery is at 23%.
Last screens are just to show battery stats.

Warning: Do not install 2.1.4 firmware

Okay, just a warning. This firmware is a battery destroyer. Within 11 minutes my battery has dropped 10% and I have no running background processes and I'm not doing anything with the unit. Just checking the screen once in a while. I've actually watched it go down 1% in a minute.
I'm telling you...if you have not installed this update...don't do it!
Too late for me.. already updated. I'll keep an eye on my battery level and let you know if I notice it go down faster than normal.
I just unpluged from the charger. It is at 100%.. I'll let you know where it is in 1 hour. I'll turn on display to stay on to simulate being used and then let it set.
Edit: Okay after 10 minutes.. still at 100% screen always on.. that was with whatever programs load into the background after boot.. I haven't killed any apps. I now have launched my Pykl3 Radar app to increase cpu from 300Mhz to 1000Mhz.. it refreshes the radar screen every 5 minutes.. we'll see how the battery does with the processor working harder.
I'm not noticing any difference really... Same battery life as before(I think, I haven't done any formal battery life tests or anything)
Seems fine for me too, but I'll go ahead and do this test.
Edit1: After 30 minutes it is still at 100%.
Edit2: After 35 minutes it has gone down to 99%
Edit3: After 60 minutes it has gone down to 96%
Edit4: After 90 minutes it has gone down to 90%
Edit5: After 2 hours it has gone down to 82%
Edit6: After 2.5 hours it has gone down to 76%
Edit7: After 3 hours it has gone down to 67%
Edit8: After 3.5 hour it has gone down to 61%
Edit9: After 4 hours it has gone down to 55%
Edit10: After 4.5 hours it has gone down to 50%
Edit11: After 5 hours it has gone down to 46%
Edit12: After 5.5 hours it has gone down to 44%
Edit13: After 6 hours it has gone down to 40%
So this averages out to a discharge rate of 10%/hr
This test was done with the screen fully on the whole time. Mostly running at full 1000Mhz and with wifi on and downloading data every 5 or so minutes.
If I let it run down to 20%, I would probably get about 8 hours which is within the specs of the Archos 101.
I was pushing the device harder than average and I believe in normal use I could get more than 10 hours.
So I conclude the battery problems aren't related to the latest firmware release 2.1.04.
Yeah, looks like you might just have a problem with your device. Have you tried reformatting and reinstall?
After about 4 hours of usage (mostly Wordfeud) with Softlocker active (keeps device awake when screen is off) I still have 82%.

Saying that your battery is depleting at 1% per minute is useless information given that many electronic devices can sometimes drop by 20% in 1 second
Please only evalute battery usage by observing how much time it takes to fully discharge.
Please check battery history with the android system tool and also more detailed info accesible with this widget: http://www.appbrain.com/app/quick-battery/com.bwx.qs.battery

Yesterday I updated to 2.1.4 and really have not noticed any battery drainage. No issue from my side.
Updating last night on Archos 70 8GB, after fully charged all night and playing net for 20 minutes continuously, battery drops to 99%. No sign of drainage too.
don't see any issue on battery drainage on my Archos 70IT either =)
It is interesting, but in this thread I appear to be the odd freak out and no one is having any issue except me...yet in the other 2.1.4 thread, a lot of people are experiencing this battery problem...not sure why that is, but the problem is there and it is real even if it is hit or miss on people experiencing it.
Yep, it's real. I put in a service ticket. I wiped and reloaded my a70 today, but it was still drawing over 800 ma listening to Pandora. I only had about 30% left on the battery, and I wanted to completely discharge it. It's stone dead and on the charge right now. I'll find out early if it helped. 3am start tomorrow. Goodnight.
(first post ) I just installed firmware 2.1.4 yesterday, and haven't noticed any difference in battery life. Although, I have noticed that 3d games obliterate my battery life now, where they just ate it before.
Wiped, reloaded, completely discharged, and charged over night. Down 20% the first hour.

Mine is still around 10% drop every hour I have wifi on for net surfing. Mine just upgraded from 2.1.2, just for information.
don't see any issue on battery drainage on my Archos 101 IT either
One thing I am noticing is that is seems more sensitive to cranking up the processor to somewhere between 600Mhz and 1Ghz at various times. Before it wasn't as sensitive and often would stay in the 300-600 range for me. This change may be why people have noticed "increased performance/less lag?"
That might be part of the drain issue or something else.
I think the point is that it is hit or miss out there. Some people get the glitch and some don't. Regardless, Archos needs to address the problem.
Ok, now this is interesting. Just to try something different, I reformatted my tablet this time and installed 2.1.3, then restored everything with Titanium. I seemed to be holding up much better. After an hour it had barely dropped. To put it to the test I drove home from work with bt gps and google maps via tether. All tolled, in 2 hours it dropped about 10%. I thought I had it fixed. Then I realized I hadn't rebooted after restoring with Titanium, so it was still rooted. I rebooted it and the wheels came off. It dropped over 10% in about 20 minutes. I ran the root app again and it leveled right off. It's down to 10% now so I have to charge it before I can experiment more, but maybe someone else can try and see if they see the same thing.
Maybe root has something to do with it.. I've never rooted and don't have a problem.. I wonder if the only people having problems are the ones that rooted.. although it sounds backwards in your case.

I was wondering the same thing. It also seems to have to do with wifi, because with it off it draws almost nothing. The exploit has something to do with the wifi, so who knows.

Crazy battery drain in just a few hours

Hello.
I've been searching various forums for a fortnight now to try and diagnose an SII issue I've been having and Google inevitably brings me here. Unfortunately, the numerous threads on battery drain don't match the problem I've had and the solutions haven't helped.
Around two weeks ago I noticed the battery life on my handset was really terrible, draining in hours. I had been using it quite a bit at the time so assumed this was the cause. However, lately it has been draining within around 6-10 hours even when idle, usually dying completely overnight despite a full charge just before then. I don't have a huge number of apps installed - maybe 20, fairly standard ones like Twitter, Facebook, Amazon, no games and no 'battery defender' style apps. It's not rooted (it's 4.0.3) and I can't root it for other reasons.
The battery drain was a nightmare, basically going from power point to power point just to keep it topped up enough to use and it was draining during idle time and deep sleep. I very rarely ever have 3G, GPS or Bluetooth switched on. Wireless is on most of the time and it generally does have a signal in the two places I spend most time (home and work). It also has a strong Vodafone signal since I'm living in a major city centre.
I tried a few things:
1. Uninstalled all but the most-used apps I had. No change.
2. Uninstalled everything it was possible to uninstall. No change.
3. Installed BetterBatteryStats and CPU Spy. BBS plus many hours of searching kernel/partial wakelocks and so on showed nothing that looked odd at all, certainly nothing taking up a lot of time or regularly stirring the phone. CPU Spy showed it did deep sleep when idle.
4. Factory reset. This included no app installations except BBS, disabling the likes of Social Hub, Gaming Hub and all other stock apps I could. No tethering or wifi sharing, no wifi, no 3G, no GPS, no Bluetooth, nothing running. It was basically a handset sitting there doing nothing. BBS showed nothing odd that I could see but the battery still drains in hours. No partial wakelocks and a tiny number of kernel wakelocks taking up next to no time and occurring a handful of times. No change.
5. I charged it before bed, took the battery out and left it until morning. In the morning it was down at 79%. This seemed weird so I bought a brand new genuine Samsung battery and gave that a try. No change in the 6-10 hour drain but taking the battery out overnight showed no drain now.
6. The weirdest of all. I charged it fully before bed, switched it off over night and it was drained completely by morning. That seems crazy to me. I can fully understand poor software or bugs draining a battery but not when a handset is switched off.
I am lucky enough to be able to get a new handset through work but this issue really annoys me. I took very good care of the phone, never installed anything crazy, didn't over charge it, the handset never got warm at any time, I'm careful with Wifi/GPS/Bluetooth/3G and location services, yet I ended up with an effectively useless "mobile" phone.
Is there anything that comes to mind that could have caused this? Point 5 above made me think it was simply a battery issue and maybe it partly was (with two batteries, how unlucky) but point 6 is just crazy. What could cause a handset to drain a battery under these circumstances?
Thanks for any advice!
Take the phone to Samsung Service Centre. No phone should drain that quick when un-rooted and a full wipe has been done
Sounds like tha battery is shot.

Um...widgets? Some widgets on stock Samsung ROMs kills your battery - I remember AP mobile news is a huge drainer. Try limiting the number of widgets you put on your homescreens maybe?
Hi...
Try:
01 - Full Wipe
02 - Install a clean ROM
03 - Disable Fast Dormancy ( *#9900*# )
04 - I use the GreenBatterySaver
After post your result !
I sugges too full reflash the stock rom and after count the batter time. If it does not help, it cold be HW error too - maybe it isn't.

[Q] sudden drop in battery life

I've got the 16gb nexus 7 (non 3g).
I've had it for less then a year and the battery life had been great. But starting over the last few days the battery is horrible. After a full charge over night my battery was down to 50% today. And that's with hardly any use. I used it for maybe an hour total and at least half of that time was just reading reddit.
I haven't changed any settings recently. This is all stock, no mods, not even rooted.
The battery usage right new says it's been 13 hours, and it's down to 48% and Android os accounts for 27% Followed by screen at 18% and WiFi at 9%. Those are the top 3 showing for battery usage.
Any suggestions as to what's going wrong it how to diagnose be fix it?
Thanks
Either your battery is bad or you have a stray process running somewhere.You might want to factory reset it, possibly even reflash your image.

Would the battery go bad that fast though? In my experience batteries usually gradually get worse. This went from losing a few percent of power to losing half power in the span of a day.
I might try the factory reset - just have to make sure everything is backed up. This tablet isn't rooted so i dont have titanium backup on it.

Doubtful it's the battery... my money is on a rogue app!!!
Hi, merkk...
It's possible, that as the previous poster suggests, some rogue app is 'eating' your battery.
The biggest consumer of power is the screen, so ensure you haven't got it set it maximum brightness... and ensure auto-brightness is enabled in settings.
Another thing you can check, is your WiFi setting... on my Nexus 7, I have 'Keep WiFi on during Sleep' set to 'Never'... it's not a setting that is easily found - it's buried in SETTINGS>>Wi-Fi>>overflow MENU (three dots, top right hand corner)>>ADVANCED>>Keep WiFi on during Sleep.
It also might be worth checking if the SYNCING of your respective accounts (Google, Twitter, etc.), haven't been inadvertently changed. Particularly the SYNCING of your Google account... which by default, SYNCs a lot of stuff and frequently. This will keep WiFi awake, and may cause battery drain. Go to SETTINGS>>ACCOUNTS>>GOOGLE and disable what you don't need to be SYNCed.
-----------------------------------------------------------------------------
It's unfortunate that your Nexus 7 isn't rooted, because there are a couple of excellent diagnostic apps available (GSam Battery Monitor and BetterBatteryStats) which provide more granular and finely detailed battery info/history than the standard Android battery info screen... and are useful for tracking down problematic apps that might be keeping the device unnecessarily awake ('wakelocks', etc.).
However, due to changes in Android 4.4 (KitKat), these apps now require root access to read and report battery stats info.
If your Nexus 7 is running any version of Android BEFORE 4.4 KitKat (and some haven't updated yet), then you don't need root to run these diagnostic apps.
-----------------------------------------------------------------------------
It's sometimes the case, with Android, that there will be occasional peculiarities with battery performance... and in my experience, it's almost always the case, it's due to something the user did... some app or widget installed. I'm currently experiencing similar battery issues on my Samsung Galaxy S3, but having run GSam for a couple of days, I think I have the culprit identified. If I can't eliminate the problem, I'll uninstall the app.
-----------------------------------------------------------------------------
Hope my ruminations are of some use.
Rgrds,
Ged.
Gedblake, thanks for the suggestions. For whatever reason, today it seems to be back to normal. The only thing i did last night was drain the batter to around 10%, turn it off, and let it charge while turned off.
Turned it back on today,used it for about 15 minutes or so playing a game. And now just about 5 hours after turning it on, it's down to 92% which is what I'd normally expect.
I'll try some of your suggestions if the problem re-occurs.
I noticed that my N7 (2012) has been draining quite a bit lately. Watching the battery stats, it seems Google Wallet was eating up some major battery. It was 2nd at 29% with the screen number 1 at 38%.
Not sure what the heck Google Wallet was doing, but I killed it and things seem to have stabilized.
battery drain after update?
For years I've had the same routine. I use my Nexus 7 all day for work, mostly notes. In between I play, (youtube, E-reader, etc). Every night I plug it in to charge and in the morning it's fully charged and ready to go. On Tues, I received the OTA update for 4.4.4 I noticed this morning that after a full night's charge, the battery only reports 50% charge. Is this the beginning of the end? What steps should I take from here? I recently bricked by GS3 so I depend on this thing now more then ever, any help would be sooooo appreciated.

I'd just restart it and let it charge again. I've updated mine a while ago and haven't had any issues.

I'm on a custom 4.4.2 ROM and I have had intermittent draining behavior as well.
Sync is off, location services off, I turn off wifi manually, and I always clear recents before I have my tablet sleep. I have greenify installed. I'm using better battery stats.
My issue seems to be similar, but I am also having battery percentages jump around.
Earlier today it went from 26% to 43% in the middle of me using it. Without charging. It frequently does this, both lesser and greater values reported. I've had my tablet shut down in the 30% range. I've had it shut itself off on 4%. I've had it drain all the way to 0% and then some before shutting down. I've had it turn itself off and when I power it back on the tablet is thinking it is at 25% or more.
I haven't been getting much more than an hour of screen time with my tablet lately. Clean fresh install of my ROM.
But I've never, until the last couple of days, had it go from a small percent to a large percent active during use. I took screenshots. I even started a thread to talk about it but nobody has responded yet.
Has anyone else ran into this behavior? Is it a sign of a soon to be dead battery?
mine got almost 30% drained on idle, airplane mode, screen off for 3 hours (tested on stock rom 4.4.3. GApps + Swiftkey + BBM + Facebook only)
my nexus 7 never lasted a day, only half a day max.
trying GSam app, hope it helps in knowing what's eating up batteries.

Heavy battery drain on each reboot

Each time I reboot my OPT, the battery level drops by at least 4-5%. I also find the phone takes pretty long to boot in general (around half a minute, if not more). With my Huawei Mate 7, rebooting was a matter of seconds, and the battery hardly lost 1% in the process. (The phone had other issues, though ...)
Who is experiencing the same? What could be the issue? Purely apps autostarting, or could it be something else? Note that I am rooted, running Xposed (with only 2 modules: GravityBox and VibrateMode) and on Boeffla Kernel beta15. I don't use Greenify and Amplify (anymore) and don't perform any heavy tasks on startup, except for loading some widgets (Google News & Weather, Google Calendar and Google Keep).
Same
Happens to me as well, using the same kernel, though i use kernel Auditor app too which starts on reboot, have greenify aswell .. battery drains by 4-5% on a reboot
Wow ... this is really such bulls**t ...
I adjusted multiple settings today that each needed a reboot. First I was at 30% battery, after the reboot I was suddenly at 20%. Note that before that, the indicated battery percentage had stayed at 30% for about two hours, despite being on mobile data with apps running in the background (not normal!) Then, I made a nother reboot. Immediately after that, the battery was at 17%, then suddenly dropped to 15% after several minutes, and several minutes later again to 11%.
Clearly this is a bug in how OOS calculates the battery percentage and something OnePlus needs to address in (one of) the next system update(s).
EDIT: LOL ... while I wrote this, my battery dropped to 7% ...
i can second this..., so if you dont want your battery to drop, dont reboot! LoL, kind pain in the *ss

Yeah, but you sometimes have to, like when updating an Xposed module or changing a setting that requries a reboot ... though I admit, none of this happens on a daily basis.
I tried soft reboots, but those seem to lead to issues with the phone recognizing the network carrier correctly ...
Hello, OnePlus, are you going to fix all of these annoying bugs in the next OOS update?
Today: percentage stuck at 44%, down to 41% after reboot, drop to 33% after several minutes. This is the most extreme case I have experienced yet ...

Whoa! I never had it THAT extreme ... I wonder what is wrong with the way the battery percentage is calculated. Seems like something with the calibration is way off in OOS.
Another observation: This doesn't seem to happen when the battery is freshly charged. I just did 2 reboots after charging to 100%, the first time it dropped to 99%, the second time to 97%. -> more evidence that the percentage isn't properly calculated while the phone is in use, hence these heavy drops from time to time vs. percentage staying the same for multiple hours.
Yep I'm seeing this too, mine even appeared to jump up after a reboot a couple of times
I am having the same issues, easily leading to 5-10% less battery after rebooting!
Also, my battery goes through the first 15 % or so very easily and then settles, there is clearly something wrong with the calibration!
There is clearly something very wrong with the battery calibration and/or the way OOS calculates the remaining battery percentage/time. I charged my phone to 100% percent over night, played a power-hungry 3D game on the train for 30 minutes, then flashed the latest Boeffla Kernel and did two reboots. I was at 78% after playing and at 64% after the second reboot (which seems "normal"), now my phone is idling at 64% since 2 hours.
Notice that the remaining time is shown as less than 2 hrs, and has been like that for 2 hrs ... this is highly unlikely. Also, what's the big gap there? The reboots surely didn't take half an hour ...
I also experienced this battery percentage stuck thing it stuck at 24%for few hours during that period my cellular data is on and sot is also half an hour during that time.
After that battery percentage suddenly drops to 20%.
Was experiencing the same, I tried calibrating my battery (Let it die, then charge it while it's off to 100%, run a battery calibration app, restart, charge it again to 100%), I used a 5V/1.8A LG adaptor (and not the original one, which seems to mess up touch sensitivity) and it seems to be fixed by now.

Abnormally Fast Battery Drain

I've posted in the Android General Q&A and
in the custom ROM forum itself, but have gotten no responses.
A search on XDA and other sites yielded nothing similar to my issue, so here—
Issue: Abnormally fast battery drain. My battery would
be fully charged, and almost immediately start draining until
it'd show 1% within 2 hrs. Screen would be off mostly (normal
use).
Been on a custom ROM since January 2017 (crDroid) and have had no problems with it since,
except 3 days ago, when the problem first appeared.
Things that are ON: LTE data (or Wi-fi), Auto apps update on
Google Play Store (never been problematic before), Location,
Things that are OFF: Bluetooth, ScreenCast, Caffeine
When I check Battery in Settings, the numbers don't add up.
I'd have battery indicator at 70% for example, but Screen,
Android System, all other apps would add up to only 7%. So
that's a whopping 23% unaccounted for.
But here's the weird thing: it drains fast until 1%, then at 1%,
the phone is supposed to initiate automatic shutdown like it has before.
When this issue cropped up, the phone keeps going for about 6 hours
or so before shutdown is started. Checking Kernel Adiutor occasionally,
I'd see a much slower decrease in voltage which probably reflects
more accurately the power drawdown situation.
Things I've done:
-clear cache (both through File Explorer and TWRP Recovery)
-clear batterystats.bin
-calibrate battery after full charge/discharge (via Root Essentials,
which basically does the same thing as manually deleting batterystat.bin,
if I'm not mistaken)
-Resetting App Preferences via Setting/Battery
None of the above has worked. Any idea what might be wrong?
My device is a Zuk Z1, with a 4100mAh battery. It usually lasts me more
than a day on normal use, but as the attached pic shows, it's at 96%
yet without having used any apps yet, has only 2 hrs of juice left.
I've tried reflashing my ROM, wiping everything including formatting data
yet nothing has worked.
I'm a light user, as I don't play games or watch videos on my phone.
Neither do I use graphics-intensive apps. I haven't used processor-intensive apps
that require constant GPS (like Google Maps, Waze) since then.
EDIT: OK, I've flashed 3 other ROMs: Citrus-CAF, NucleaROM and stock, and the problem persists.
By doing the above, I've crossed out the possibility of it being the ROM. Neither is it the battery
itself, because it would've shut down by itself at 1%, yet at 1% I can last 6 or 7 hours of light use.
Anyone out there have any idea?

My device is a Zuk Z1, with a 4100mAh battery. It usually lasts me more
than a day on normal use, but as the attached pic shows, it's at 96%
yet without having used any apps yet, has only 2 hrs of juice left.
I've tried reflashing my ROM, wiping everything including formatting data
yet nothing has worked.
I'm a light user, as I don't play games or watch videos on my phone.
Neither do I use graphics-intensive apps. I haven't used processor-intensive apps
that require constant GPS (like Google Maps, Waze) since then.
EDIT: OK, I've flashed 3 other ROMs: Citrus-CAF, NucleaROM and stock, and the problem persists.
By doing the above, I've crossed out the possibility of it being the ROM. Neither is it the battery
itself, because it would've shut down by itself at 1%, yet at 1% I can last 6 or 7 hours of light use.
Anyone out there have any idea?

Try XOSP. was very good by tech mashido for battery.
And 1% don't last that much. It's a long prediction.

What exactly do you mean by "long prediction"?

For me 1% never stayed for less than a min.
