Hi,
I have a GT-I9100, running CM10. This has been working great for weeks (since first CM10 experimental). Some time back I started experiencing problems while charging, and I thought it was a faulty charge port. This problem magically "solved" itself, but now I am experiencing random shutt off, freezes, part of the screen going black before it turns off completely. Some times I get to the boot animation, some times it turns off and works for a while, before shutting off again. Tried a complete wipe/factory reset, to no avail. The battery stats also seems pretty random, going from ~70% to ~10% after turning off and on again.
I was reading here (http://support.t-mobile.com/docs/DOC-3152 (I don't own a T-mobile)), and it said this could be caused by a faulty battery. I have taken some photos of the battery here: http://imgur.com/a/FVyK0 ... To me it seems that it could be some visible swelling to the battery, but I don't have anything to compare it with. Any opinions??
And could a "faulty" battery be the cause to these problems (which to me seems to be software related)?
Which kernel are you running?

1. the battery is a little swollen at the middle
2. use a thin a paper to support the battery to ensure proper contact with the gold pins. this might resolve the random shutdown issue
Did you undervolt and/or underclock CPU and/or GPU? If yes, less aggressive values may help.
The crazy battery percentage can be solved by charging your phone to 100%, then clear battery stats and reset your fuel-gauge chip.
Tell me if this helped or not.

I installed the latest CM10 build today, 10-20120821-EXPERIMENTAL-i9100-CODEWORKX, kernel 3.0.15-CM-gea1d0d7, baseband I9100XXLQ6. I have however experienced these problems on other CM10 builds, but before I started experience them, I was running CM10 without any problems.. I could downgrade to CM9 and check I guess...

I don't think it's in any danger, it happens in old Nokia phones. I personally experienced this in my old n95.
It looks like as a result of too much heating, maybe

I have been checking out calibration, but there seems to be some diverging information. Should I charge it 100% while using it, or while off? Should I first drain the battery? And what do you mean by "reset fuel-gauge chip"?
As you can see, these battery stats don't seem right: http://imgur.com/Xnv6W.png

Wow that's the exact same thing happen to me.
The phone would shuts off by itself at random battery percentage. then I try to turn it back on, sometimes it just shuts right off.
At other time it would continue running with the battery slowly increasing. The graph of battery usage is really similar to yours. It would have those "valley of death" and then comes back alive as a short lived battery.
I am trying the battery reset by draining the battery until the phone really cannot be turned on (even the monitors), take off the battery for 2 minutes, charge it while it's off, unplug as soon as it reaches 100%, charge it till 100% again. I have read other thread saying that the taking out the battery part is at the end of the charging (100%), not at the beginning (0%). So I don't know which one is correct way to reset the battery.
Before update, I did not experience this prob, but only really hot cellphone while charging and fast draining battery even with 2x battery apps. Well, I had like 100+ apps, so it's understandable, but now, I have a very few apps (10+) but it's doing this magic trick to me.
Oh, and I noticed my battery is swollen and bulged at the middle too.
Anyone has an answer if it is a battery problem or just my mind going crazy?
I'm having exactly the same problem while running CM9. However i've noicted that the same thing happens while running stock as well. No overclocking or undervolting here.
My battery is swollen as yours is as well. Could it be a faulty battery?
Looks like it was the battery after all.
The service centre lady told me that my battery was FUBAR. Bought a new one and the problem seems to have disappeared.
She said it happens because of overcharging. Is that true? Thank god the battery was cheap.
It was the battery for sure. Ive been getting amazing battery life ever since I bought the new one. No more unexpected shut downs or any of the problems i was having.

I have a Sprint Galaxy SII (Epic 4G Touch) and have been having the same issues. My battery is also swollen and I have been trying software fixes for a couple of weeks. I ordered a new battery and am glad to find that your very similar problem was solved that way.
Thanks for posting about this!
I was really suffering from massive battery drain....see here - http://forum.xda-developers.com/showthread.php?t=1933012
ive now found out that i am having a very wierd problem...My rom is showing some 30% battery while 4ext shows 50%......Sometimes it is exactly the opposite....Once i discharged my phone to 2% (rom reading) and when i saw in recovery it says 17%....
I have completed many many cycles of battery from charging to full....and discharge to 0.....Also i used the battery callibration app SEVERAL times!!!!........But nothing seems to work...
Can somebody help...Please

I had this issue with my old battery and old charger,
Now I dont use my phone while charging , I charge other batteries with the wall charger while using other ones and everything is fine now.... battery % seems to be same in both android and recovery.
I have that same issue too. Lol maybe the recovery can't read the battery correctly. It'll show up higher in recovery and then when I reboot, it will read the same way like in recovery. Tried numerous batteries with the same result. Although I havnt tried battery calibrating. Ill give that a shot.
Is there any solution ??
Try klect's solution and go into recovery, wipe battery stats. Then let your battery drain and die. Then charge your battery back to 100% with no interuptions like pulling your phone off the charger too soon. When you wipe your batt stats you are getting ready to recaliberate your battery. After you let it charge to 100 percent. Let it drain to 0 a couple times to recondition your battery.
You do know that the evo 3D gives around 3 hrs of screen time dont you? even on stock rom on normal usage. If you have the wifi on all the times you'll get around 2:30 maybe 3 on a full charge.
Your battery certainly is draining faster than usual but have you tried keeping it idle and seeing what kind of drain you get? From that screenshot in the other thread it seems like your phone is getting some heavy wifi browsing or something (and do check if facebook or email apps are the culprit. Having push email on drains a lot)
And the recovery/rom reading wrong stats happens all the time. just recalibrate your battery like these good folks here have already suggested
Yes i keep wifi on all the time...
But once i kept my locked for abot 3 hours after full charge...when i unlocked it showed 99%...i was happy and i didn't do anything just surfing my screens it dropped very very fast to some 70 % !!!!
Also please hit our thank you buttons please. Even if you didn't get the exact answers you wanted. It's appreciated for helping one another.
you really should check your apps battery usage using one of the apps ramjet73 told you about
ramjet73 said:
There are a bunch of tips here.
Usually that kind of drain is caused by an app. Try running a stock ROM for a day or two and see if the issues go away. Or use one of the battery monitoring apps (BetterBatteryStats, SystemPanel Standard, Battery Monitor Widget) to determine which app is causing your drain.
It may take some work on your part to isolate the problem since there is no global solution to battery problems.

top culprits are mostly facebook,email exchange,google maps and pretty much anything that syncs alot
Also try using you phone on min brightness auto brightness is also a battery killer
I cant beleive no one asked you this but which kernel are you using? And is it overclocked?

Hey guys.
It seems like almost everyone with battery drain issues has Android OS at the top of their battery stats.
I just want to share my experiences with this particular Bug.
Maybe it will help anyone. Please share if it also helped with your problem.
I had the Android OS bug since I dropped my phone a few months ago and had the screen replaced. The guy who replaced it (official Vodafone shop employee) said that they didn't just replace the screen and that something else was also damaged (they didn't say what) so they also replaced the rest. Well, that's when the Android OS problems started. I tried many ROMs and many Kernels. Sometimes the problem went away for an hour or so, but it always came back.
Then I finally decided to use BetterBatteryStats two days ago (I really should have done this earlier, I know...). I came to the conclusion that I had some sort of the well-known "fuel_alerted" bug, since fuel_alerted was the service that kept my phone from going into Deep Sleep.
This bug should have been fixed long ago but for me it somehow still persists, even on stock JB.
It didn't only drain a lot of battery (I had 8-10h maximum without doing much), it also used up a lot of CPU time, effectively slowing down the whole system to the point that I wasn't able to use Spotify on my phone without severe stuttering.
Well. I found a solution to the fuel_alerted bug.
The procedure is: turning airplane mode on, shutting phone off, taking out battery, putting it back in after a few minutes, turning phone back on.
This solved the problem. No more Android OS draining the power. Phone goes into Deep Sleep again. Only 2% drain after an hour. Spotify runs smoothly again. Yeah!
BUT well... It seems like the problem comes back randomly for me, today I had to replace the battery 5 times...
Now I am trying to strictly follow another "rule" to keep the problem from coming back: Always waking and unlocking the phone before plugging it in or out of power. I never did this before so it could have been the cause of the bug. Now let's see how long it stays bug-free.
If it still doesn't help, I guess I have to conclude it's some kind of hardware problem, which could only be solved by Samsung...
EDIT: Nope. Problem still there. So not really a fix, but maybe still helpful for somebody.
Okay, what ROM are you on?

It's the up-to-date stock Samsung ROM I guess. See attachment for infos.
Damn, it seems like the problem just came back without me doing much. I only checked BetterBatteryStats every 30 minutes or so and recieved 1 SMS just a minute ago. Seems like the bug started 20 minutes ago, when battery was around 78%. Now it's draining battery like hell again, Spotify stutters, Deep Sleep won't work...
Guess I'll have to pull the battery again.
Since I'm pretty new to all this: What kind of information would be useful to narrow down the source of the problem?
I can provide my BetterBatteryStats screenshots and logcat/dmesg files as well as my Android Battery Stats screenshots.
Is there anything else I could post?
Yeah, screen shots of partial and kernel wakelocks.
Sent from the little guy
I just rebooted the phone, waited for a few minutes and took screenshots.
Here they are.
Okay, this is what you need to do now, drain it empty, charge it (while phone off) till 100 %. Remove the battery, wait for 90 sec or so, put it back and power on.
It's a placebo, but it might work.

I don't know much about kernel and ROM stuff, but I was just wondering...
As far as I understand, the fuel_alerted thing turns on if the battery charge goes below a certain threshold. The old bug with it was that, when recharging, the fuel_alerted thing would sometimes still stay on, even if battery charge is no longer critical.
Could it somehow be possible that this threshold is not set to 15% for me, but something around 80% due to some horrible bug?
This would explain why it suddenly turned on at around 80% when everything was fine before.
We're trying to adjust your fuel gauge and sort of calibrating your battery.
Sent from the little guy
Okay, I did exactly what you recommended.
Everything went well for about 2.5 hours.
Then the fuel_alerted process began again, but this time only for a short while apparently.
It took about 5 minutes kernel wakelock time in a 30 minutes measurement.
Way less than usual and when I check now, it's no longer active.
So. The problem might still be there, or it might not.
Do you recommend going through a few more recharge cycles to get the gauge set properly or do you think this won't make it better?
By the way, thanks for your quick responses!

Not really.
Now, when it gets to 15% or so plug it in (while phone ON), get battery calibration from play store.
Run the app, when it gets to 100 % hit calibrate. Plug off the device. Turn off.
Take out the battery for 90 sec again, reinsert it and power it on.
That calibration app is another placebo but as I said before, placebos sometimes work.
Sent from the little guy
Since the battery calibration app requires Root access, I flashed a Dorimanx kernel a few hours ago. Then I did a factory reset and the battery-removal thing. 5 hours have passed now without the bug, 3h of which were without wireless access (maybe it correlates with that).
I'll now let the battery (slowly) drain below 15% and then recharge it with phone on overnight. I will use the battery calibration tomorrow and will inform you about the results later.
Thanks man!
Good to know

Okay, here are some screenshots.
From the graph you can clearly see when the bug started.
Is it normal to have >26 kworker processes running?
Something else that concerns me: >2h without or with unknown signal. The whole day I was in an inner city area where the signal should be good...
Can you conclude anything from the screenshots?
I will now try something which I also should have tried earlier
I have a spare battery (not original samsung, less capacity) which I just put into the phone.
I'll let it fully charge with phone off and then I will try if the problem persists even with the other battery.
If it doesn't, the problem might come from the battery itself...
Is this a good idea?
No it's not.
You gotta post detailed info there, we can only guess what's draining your battery.

Hello! I bought this phone last month. Since I got it, I've never experienced any problem with it. For four days, I noticed that the battery drains very quickly, without any logical explanation for this. The data connection is turned off, Wi-Fi is turned off. Last evening, I charge it to 100%. This morning,I found it turned off, with 0% battery. What solutions do you have to solve this problem? Have you encountered this problem?

Can you please provide some more details on this?
I.E. What is it plugged into to charge? Laptop, Desktop, AC, etc etc.
- I ask this because I had a phone that would actually consume more power than a USB port could put out. when turning off the laptop, it actually allowed a back drain for some reason, and the next morning the device was dead. (Not this phone)
Also, what applications are running? Any?
Finally, you can try to retrain your battery... Wiping stats does not work, ever. So despite what anyone tells you, don't do it. You're just wasting time. SOURCE
So, how do you retrain your battery? Let it die completely. Then plug it in to charge. Don't use it while it's charging if you can help it. DO NOT remove it from the charger until it's at 100%. Once this is done, use it til it dies on it's own. Then yet again, charge it fully and then go back to your normal use.
In some cases, these batteries can go bad, for various reasons. A quick test, but is not always trustworthy is to spin your battery on either side. If it makes more than 2 full rotations, it's swelling and going out. Replace it.
The best alternative is to take it to a battery shop, and let them put it on a Cadex machine. (Pronounced Kay-Dex) ... This machine will charge and discharge the battery several times over a few hours and truly test the current life -vs- the life it should be. Anything rated less than 80% remaining life should be replaced.
SOURCE: I work here
I charge it only from power outlet, with stock charger.

6 hours 40 minutes from 100% to 10%, and the phone in stand by! Cell standby - 45%, Phone idle - 48%, Screen - 7%
And all this after a hard reset and retrain battery! The battery is almost new (aprox 1 month)!
I want it to make a screen shot of battery drain, but I have no clue how to do that on LG L9...

I attached a screenshot. Yesterday I changed the battery. Same problem! I take it this screenshot this morning, after I fully charged the phone ... Same problem, a new battery.
Can you please tell us what applications you have running in the background?
Also deactivate google now.(or the google services in google maps). download and install GSam Battery Monitor and after a cycle tell us what applications are eating your battery the most. It's clear that you either use yout phone(screen on time) allot or there is/are some applications that prevent your phone from going to sleep.
I use battery widget reborn and it shows me wneh the phone woke up,when the phone had the screen on,wi-fi on,gps on. Try it as well.
I also had battery issues when on JB. I downgraded back to ics. It's much more reliable when it comes to battery life. And the performance is about the same.
I don't have any app installed. After i replace the battery, i made a hard reset and I did not installed any app. I will install cpuspy and betterbatterystats for more results. I will back tomorrow. Until than, maybe you can provide me more advices. It can be from a damage sim card?

I removed the sim card, but in flight mode is the same problem... The last solution is to change the rom with a custom one. Any recomandation?
It's not that. Not the signal. It's the firmware. JB has these problems. In ICS Display is the major consumer followed by Phone Idle and Cell Standby.
I also had these problems in JB and reverted back to ICS .
I would advise you to install CM 10.1 on the phone. The battery life is better than stock. I get around 12-16 hours normally. The latest RC4 has fixed almost all the bugs present in older CM 10.1 variations. Give it a try.
I will root the phone and I will give a try with CM 10.1 or I revert to 4.0.4. If all this will be for nothing, I will sell the phone!

On ICS you will get great battery life Telling from my experience as i have reverted back to ICS after trying JB and CM 10.1( both have very poor battery life ) . So instead of wasting time just flash ICS and forget about battery issue :good:
Where can I find a tutorial to revert to ICS?
Same question. Can some one please give a step by step guide on how to revert to ics for l9

Use the offline flash..
I also reverted to ICS and the battery drain keeps like a countdown
I have the p769, and I offline flashed up to V20D (and rooted). Removed some tmobile bloat, and I have pretty decent battery life. I guess I'm lucky.

Well, for starters, not sure if the battery temperature chart you attached will help.
So you say it goes from 100% charge to 50% overnight? If so,you got some serious issues there. Typical loss is from 3-5%.
But 50 is absurd.
When you check the battery usage, what kind of usage is going on? Display of course is a biggie and uses the most. It's possible some application is keeping the tablet awake/display on. This might explain it a little.
I will explain how to read it. If the usage chart states "Display 54%", then it means of the 50% battery you lost, the display was responsible for 54% of "that" figure. That's how to properly read it.
But you need to find out where the drain is. I suspect a "rogue" app or a bad battery perhaps. A rogue app can certainly cause it, as with running some strange mods that just don't get along well. So you are going to have to hink back and remember what you changed just before you noticed the drain.
You can install an app called Better Battery Stats, and it might actually pinpoint what is causing the severe drain.
You have already installed GSAM Battery Monitor, so you should be able to find the cause for your battery drain.
Do you already have the Root Companion App installed, too? If not you probably should do so, this should provide better stats. Your tablet needs to be rooted, though.
After the drain appeared, open the GSAM-App and select ´App Usageˋ or so (my app is in German, so I donˋt know exactly). Then select ´Show Kernel Wakelocksˋ or so.
Now you should see how long your device was awake and what caused this.
Hi guys! Thanks for your help here.
I have found out now that the battery is definitely faulty as it went dead last night and I tried charging for 2 hours and it still won't turn on.
I am sending it back for a replacement.

No problem. At least you know the cause. Personally I can't recall a bad battery on a new tablet, but I would think it's possible as many tabs as are sold. Sucks you got one though.
