FIX and INVESTIGATION: Android OS (battery drain) problem on Gingerbread

CASE CLOSED!!! Please read bottom part or flash stock GB 2.3.4!
I have posted this already on another thread (almost word for word) but I just really want you guys know and not panic about this problem and avoid going through difficult fixes like deleting system apps, recalibrating battery or even resetting your phone.
Since JVK was released, many observed that Android OS sometimes get hungry and devours battery. For some reason it is triggered to go berserk. Others say that the main culprit is the Auto update app. But other apps like Google Maps, Latitude and even just in a place where there is very low network signal or Wifi reception could also trigger this problem.
Now, I have a very simple solution: Turn off device, remove battery for a minute, put it back then turn it ON. Yes it is just that simple, REBOOT YOUR DEVICE.
Yeah after you turn on your device Android OS is still on the top of the list with high percentage but I believe it is just as it is because it previously consumed a lot of battery. All you have to do is observe again for an hour if your battery is dropping again, look into the graph and see if it is still steeping to the bottom. If it is dropping like Mt Everest, do the procedure above again.
If not, you will observe that after a couple of hours Android OS's percentage is getting low. Problem is fixed, (temporarily though).
Why go through deleting apps, recalibrate battery etc when you could just turn off your device for a minute?
I have experienced it a lot of times already (one of the first users who upgraded to JVK) but it doesn't bother me anymore. Turning off then on your device is very simple ain't it?
I highly advise that you do not touch anything on the sensitive part of your phone as there is no known single root of this problem. Just like I told you, many situations or apps could trigger Android OS to go berserk. Until there is no definite solution to this problem, I suggest you do the above procedure and save yourself from going through the pain of removing system apps, battery calibration or even hard reset.
By the way my battery usually lasts 3-4 days unless I made Android OS angry again.
INVESTIGATION
INVESTIGATION CLOSED!!! The culprit is caught. But the fix is not so simple. Only Samsung and genius devs (apparently the fix requires closed source modification) could fix this. If the problem occurs on your device, just do the temporary fix above. Please do not try to mess with your device for now.It is now fixed in XXJVP 2.3.4!

All this is due to Tatsuya who pointed us to the right direction. A big thanks to him for helping us in this investigation. CASE CLOSED

Ok thanks for the credits.
This previous link I gave explains how you can use watchdog to alert you when this bug triggers, so you know when to reboot your phone to stop this leakage (if you really want to stay on gingerbread until a fix is made by Samsung).

Guys if you want to help out please please please dial this *#*#4636#*#* and check "Usage Statistics" and let us know the top 3 items on the list! (highly suggested by {Angel}).
Below are some of the possible culprits currently pointed out by some users (I will update the list based from your feedback):
1. Software Update service
2. Google Maps
3. Latitude
4. Low network signal
5. Very low WIFI reception
6. Auto updates in Market
If this helps, a simple thanks is enough

Those of you with high drain, you can also check battery history through *#*#4636#*#* and see what you have under other usage 'running' and see if your phone as not been sleeping lately. I get this occasionaly with froyo and I suspect many people do also. A reboot fixes it for me, after that my battery usage is superb, but it's annoying as hell.

Yes just like I said in the first post, this is just a temporary fix. But I think users should just do this rather than touch anything on their phone unless they really know the source of the problem.
That is why I suggested that they report what could be the possible triggers, like apps or situations, that make Android OS to awake and gobble up the battery. If we could just pinpoint those triggers maybe we can now figure out the root of the problem. Your fix of removing a system app, the auto update app, is not even the single source of the problem. We just do not know if that app is an essential app or not. Sooner or later you will have that problem again.
I am not saying we should just sit and wait. All I am saying is if you are a plain user and you do not know the exact root of the problem, then just do what I suggested. But if you are a dev and is exploring the root of the problem, then do as you like and we will be most thankful if you find out the answer.

Rebooting works, and it seems to be working until you start some apps again. I have the same apps installed as I had on JPY, but JVB drains my battery dead in half a day.

Could you pinpoint some apps? I will update the OP to keep track of possible culprits so that others will avoid triggering this problem. Thanks!

I once saw that the battery drain from 95% to 9% after one night, and the android os used most of it. I rebooted my phone, and the problem has gone away, since. Happy with Gingerbread!

I'll give it a go! thnx

Active Widgets: WeatherBug Elite, 3G Watchdog, BatStat and Calendar.
Apps: All from above plus Twitter, Titanium Backup, Facebook, Twitter, Tapatalk, Camera360 Ultimate, Root Explorer, Foursquare.
Mostly I use the Twitter client and the browser. Location services are disabled.

It is hard to figure out from the above apps or which is the most probable suspect. Just incase the problem recurs on your phone, dial this: *#*#4636#*#*, Go to Usage statistics and Battery Information and please report back (include also information on the Battery Use in Settings).
I hope we can help others avoid having this problem until there is a fixed solution.
Thanks!

Did what you suggested and pulled the battery at 30% waited 5 minutes and put it back in.... 1hr later it was at 35% (WTF!) and 30min later it was at 38% (WTF!)
im assuming its recalibrating?

Not necessarily. Maybe the battery meter is anticipating the fast consumption rate of Android OS that is why when it got fixed, the meter is able to readjust the readings based from the current consumption rate of your phone. Good to know it helped

Maybe use the 'forbidden' task killer? Works for me... Maybe im imagening it but works.
Btw my battery goes quickly down after getting below 25%. My battery not calibrated? Should i.calibrate it? I have this program to do it but am afraid that calibration goes wrong. (example what if my battery is 95% and will calibrate to 100. What if.i charge my battery higher than this.. Will it show 104%? Or will android stop working for it cannot be displayed in the notificationbar.
Using cm7.

You do not have to recalibrate. Cm7 has a known issue about battery. I think you cannot charge past 94 or 95 percent and battery usage is a bit terrible. Please refer to cm7 thread for possible fixes, (the last time I checked their thread, they say it is probably kernel related).

Just turning off, pulling the battery and turning on does do a lot for me! i went from 10% per hour to only 1%! great thnx!

Hi,
About battery drain in gb, once fixed the wifi sleep policy issue ( by setting it to "never") u shouldn't have batt drain, but i've installed green power ( juice defender do the work too i think) to get some wifi management possibility back and it improuved my batt life.
But never the less, my battery won't last more than one day of hard usage ( being hanged on xda all day long, for instance ;-)
Sent from my GT-I9000 using XDA App

Guys, just turn off the task killer, it helped in my case. looks like its not working well on ginger

Rebooting works just temporarily.
It will come back the next day or so.
This is not a solution at all tbh.

Guys, on Gingerbread I've had battery drain two times:
1. Had about 14% drain in 3 hours all of a sudden, without doing anything at all. Just started going down for some reason.
2. This morning, saw about 40% drain in 7 hours..
And, both time I solved it by Clearing Memory from the Task Manager.. Went back to normal 2-3% drain per 6-7 hours after that..
So this might also be a solution. Go to Task Manager, RAM tab, and Clear Memory..

i'm on ginger also and my battery acts weird. 2 days ago i charged my phone over night while it was closed. the battery holds for 15 hours with massive use.
last night i did it again, but today it went from 98% to 80% in about an hour !
this is really weird.

Did you manage to check first what is running on your device by looking into Battery Usage settings? I think you have a case of rogue application running in the background.
If you have not rebooted yet could you please attach a screenshot of the battery usage list and graph? In that way we might possibly identify the app running prior to the clearing of memory. Thanks!

[Q] ultra fast battery drain

i'm losing almost two percent battery per minute on my tab, what the heck?
Its so fast i'll have to keep this post brief since i'm posting from it.
Already checked the battey break down, screen is vastly dominant but its been off.

Power cycle? How long has it been happening? What firmware are you using, stock or rom?

Click to expand...

Not sure what you mean by powe cycle, but i just took it off the charger after a 6 hour charge and the problem persists
android version is 3.1,
2.6.36.4 cyanogenmod+root @pershoot-ubuntu1 for the firmware
Rom is starburst.hmj37.uekme p7510ukeme
My battery has gone from 100 to 70 since i started typing this

By powercycle I mean have you turned the Tablet totally off and then back on again?
Have you checked the ROM's thread in the Dev forum for people with the same issue?
How long has it been since you made any changes to your tablet? I'm talking about updating the ROM, installing the ROM, changing kernels, etc.
Unless your battery or some other component in your tablet has gone bad the problem is probably due to something in the ROM or kernel you're using. If a reboot(powercycle) does not fix it your first stop should be the Starburst thread or wherever you got your ROM from. If it's not a hardware failure you're pretty much guaranteed to not be the only person having the problem.

Is there a known issue on the rom with respect to battery-calibration like in the original Samsung 3.1/3.2 ROMs? There is a thread somewhere here how to calibrate your battery-reading, just search for it.
May not be what is happening to you, maybe it is. Is the percieved drain constant up 'till the end'?

more data;
powercycling didn't do anything, and neither did resetting battery statistics either
the reports of starburst rom having battery draining properties are....mixed..
most seemed to be solve by uninstalling a certain app (all the apps suggested are ones i do not own), and it seems all these cases of battery drain are FAR less severe than mine

[Q] battery drain already?

Hey guys. First proper charge from around 3% too 100% and I'm getting battery drain already, I thought this issue was resolved in lollipop? Not the mention the emense heat that comes off of this device
Check out the picture and get back to me. Thanks.
Jack

Same thing is happening to me... I don't find that the drain is really so bad, as I still get pretty great battery life, but does appear that this issue is still present in lollipop. Seems pretty wide spread among Android users.

I had an iphone for about 5 months. Went back to android and the problem still persists I got 3.5 hours of screen on time yesterday. Take a look at this

Also getting battery drain, the main offender seems to be the "mobile standby" which is always around 50-65% for me.

I think this was an error in reporting in the stock firmware, I haven't had a problem with the battery, in fact it's been really good. Since updating to B132 (GRA-L09) the battery usage seems to be reported correctly.

Interesting, I'm not sure what the normal drain should be then. My HTC One had a pretty good battery life, but it seems with this phone the battery drains quite fast when I'm using Chrome and WhatsApp etc. The power saver reports Chrome uses a max of around 10% but the rest use very little %, yet it seems I'm using around 30-40% of the battery in around half an hour.
Do you think using a custom rom (when they become available) would be any different?

Not sure if a custom rom would help. Are you rooted? If so you should have a look at betterbatterystats which should show you what's using up the battery.
When I'm mostly on wifi I can get 5 hours of screen time with 32+ hours running time.

i have the same problem with the "mobile standby" batery drain
i did a clear data/cache then factory reset, and now it's ok
androyd system still drain batery pretty much
sorry for my bad english

Was going to wait for a few roms to be released before rooting, but the battery life seems so poor I think I'll do it just to find out.

I've had the same Problem with the battery drain and analysed this with the Wakelock Detektor (needs root). Cause was the "NlpWakeLock" thats part of the Google Services. Then I disable the Google Location History everything went well. They are a lot of of useres, who have the same problem. The only real solution (If you want to use the Location history) is a Xposed module for that you need a working Xposed framework.

I have now disabled Google location history, hopefully this fixes the problem for me too.

Need advice about battery drain

Hey everyone, I purchased the 6P a week ago and I really don't understand the battery in this thing.... I'm coming from LG G3 which never faced battery drain during stand by. I am not even using the 6P (still haven't migrated from the G3) because of the unreasonable battery drain during sleep, I have WiFi always on and (no I don't accept to turn it to Never during sleep) I never did this with any phone anyway, my G3 doesn't lose more than 1-2% during the whole night (7 hours).
Please take a look and tell me if this makes any sense because I'm thinking of returning the thing if it's not just a software issue:
Time of screenshots:

Taken today, phone left untouched at home.

Battery life is really hit or miss, many lose 0-3% during the night while others like yourself lose a ton. Try changing your WiFi to either 2.4GHz only or 5GHz only, as some found that helps out. Custom kernels can also control WiFi wakelocks, and I've found running Franco kernel does a great job at helping standby life.

How's the signal strength from within your home? Having a weak cell signal can assist in battery drain. However that's some serious drainage. I'm thinking you have one or more wakelocks preventing the phone to deep sleep. If you're rooted, greenify is a must. It has boosted my battery life by a ton. I would also try to get some more battery stats applications. Better battery stats was/is my favorite app but I'm not sure its working on MM

Although it is not convenient to switch between the 2 bands ( Work is on 2.4GHz and Home is on 5GHz) but I will try it to see if it helps any.
Do you think this will be fixed with software update? and is it because Android M or because 6P on Android M?

Signal strength is fine at my home ( never faced an issue with G3).
I haven't installed anything that can hog battery like that, I only set-up Email, Hangouts to Sync, I never used Greenify or any battery saving apps ( The battery should last as advertised with it's standard capacity), i'm not asking for a magical battery life, just what's expected of a 3450 mAh.
I'll post Sambatterystats results shortly.

See if WiFi scanning is turned off

Many say the battery drain issue really spiked with the update to Android 6.01. So it appears to be SW related, and not HW, FWIW.
I found my fix is as Geoff53 said above, install a custom kernel (Kylo in my case). And I use Greenify on top of it. Great battery life now.

I hope it's just the 6.0.1 .. because I really would hate to return it..
Well, I'd go as far as flashing a custom ROM if that would completely solve the problem, not just the Kernel.

I initially had bad batter drain, not now. Unplug 6:30 am and 10pm still have 45%. Use to be dead by 7pm. I found the culprits were bad apps that I thought were OK. Ebay, Amazon, Facebook, ESPN, Waze.... when I deleted these and a few more, then rebooted all was good. Haven't tried putting them back though. I leave GPS, WIFI, blue tooth... all on. Even have 3 mail apps all set to "push." I don't twitter though.
Make a back up with Titanium or MyBackup, factory wipe and reset and see if your battery improves with only basic apps and mail. Bet it's bad apps. If improves slowly add apps until you find the culprit.

In my opinion, the " Bad App" theory is getting a bit out of hand. I installed the same apps as on my G3 (never had a bad app on it) , and 6P has been factory reset and insatlled nothing at all, only logged into gmail and hangouts, and I tried with the (WiFi during sleep set to never ) then the drain is not as bad anymore but I lost realtime push notifications which is unacceptable.
Now if believe there are so many "bad apps" then we can have the Doze which is supposed to minimize app drain if not terminate it, but that's not the case here obviously, so I think it's actually specific WiFi bug on Android M and not bad apps.

Battery Drain when off

Has anyone any ideas, if I turn my x727 off the battery will drain to zero in a few hours. If I just set to airplane mode battery is good for three or four days. Accubattery shows battery in low nineties for remaining capacity. Currently using AICP pie ROM but also did this on lineage and AEX ROMs. I don't even know what to check as phone is off. Any help appreciated.

Only thing I can think of in order to discard some things are:
When did you notice this? after some modding? Have you flashed the recomended firmware for your device from the first post of AICP thread?
Then just for test:
While the device is off, connect the charger to see if the charging screen appears.
Then power on and once in AICP reboot to TWRP and from there just power off with TWRP menu, wait few hours, power on and see if there were battery drain while off.
Regards.

Thanks, it has done it for about one year, kind of thought about powering down from twrp. Have just been hitting airplane mode instead of powering down all this time. Firmware is correct. I thought something must be hanging. Appreciate the insight.

Just tried the shutdown from twrp. Battery went from 45 to 16 in one hour of shutdown. I am befuddled.

hello i have the same problem. i bought Lex722 as used one
i installed fresh Lineage OS.
when phone is off it drains in about 1-2 days down.
So i replaced the Battery with a new Battery. But... it get also down.. to i think its an hardware problem
one more thing: i charged from 0-90% . the Battery gets really hot. (Original charger). so maybe something with charging unit in the phone not ok

I have an X722 and I have a similar problem, after changing the display I have some problems like the one you mentioned, battery drain in stand by and my smartphone charging above 80% it shuts down and starts draining the battery, has anyone tried Qfil to try to solve this problem? or is it a hardware thing?

I think I had something hanging and the phone not really shutting itself off completely. Did a wipe when doing an update and it fixed itself.

I have similar problem too, have X722, started somewhere in summer, spring where basically discharged by 10-20% daily when not using..
I always update to latest AICP. Just replaced battery today and still seems there is a small drain, charged to 100% for the first time, 2 minutes of usage and already down by 3%.

This may or may not help. You need to track down all the hogs. These were two that caused me endless issues. I tried disabling backup by switching it off and this and that... until going full rambo on Google.
Google Backup Transport and Backup Framework wuv to run amuck even with screen off.
I finally package block them and firewall blocked them. Clearing their data, as well as Goggle Play Services* and system/residual data caches if they act up.
Now it's stopped.

Can I successfully disable them by just disabling their services in MyAndroidTools? (just checked and i already had them disabled)

Yeah but portions* will still run in the background just like the malware it is.
Hence the firewall and the frequent data deletes.
Maybe 10 or 11 is better behaved but it doesn't seem that way from what I'm reading... they look worse than Pie. With unrooted phones they even block more user diagnostic tools than Pie, perfect. Pretty sure my 10+ will run on Pie for its whole service life because Google dropped the ball.
Fortunately Pie is a good OS... add to that AT&T and their partner Samsung are notorious for device killing near update end cycle firmware.
Not updating is simply an act of device self preservation.
*hopefully you can pull these weeds out better than I can on an unrooted device.
Each user/device is different though, good luck
