Try to completely empty the battery by rebooting after your phone shuts down because of low battery. Keep rebooting it after it shuts down again till it doesn't want to boot anymore. Till the battery is completely empty.
Then Charge it again and leave it on the charger for more then 20 hours.
Don't know if it's gonna work but give it a try
EDIT: Q? are you using a custom ROM ??

Ok I'll give it a try, thank you. I have this problem since i flashed a modaco firmware and wiped my battery cache via cwm. Anyone else having those issues?

I reverted back to stock on my O2X and I can get 48 hours out of the battery. I had the same issue as you and reverting back to stock seemed to cure it too.
Just an FYI I thought I'd share.

48hours when you are using him or 48h max on standby

USE phone heavily. Use it till the system turns OFF automatically
Turn OFF phone
Charge till it says it is FULL
Start phone in RECOVERY Mode
Select Advanced CWM Features
Select Wipe Battery Stats
RESTART phone

Sorry, should have given more detail. That 48 hours is with general browsing and social networking with a fair bit of video recording and camera use. No 3G though. All data was over WiFi.
Certainly not just stand-by though.

No full power use of the processor i understand

i thought i had the problem too with the MDC fear 5.3 but it just jumped from 98% to 100 after 10 minutes so its probably a mistake which solved itselve if you charge it long enough.

Didn't work for me, i did it exactly this way, charged it for about 10 hours, booted in recovery, wiped the battery stats and it stills shows 97% when i boot it. However, it's not a disastrous failure, i can live with it and hopefully it gets fixed sometime.

Finally, i found the solution for me. After i reflashed the stock rom, where this problem doesn't occur, i flashed a modaco rom again WITHOUT WIPING THE BATTERY STATS. Now it's all working fine, i charged my phone to 100% a few minutes ago. Hope it will help some of the people, who are still having problems.

Does kernel version has anything to do with this issue?

Don't think so, i tried the stock, Paul's kernel from FR12 and the EternityProject Kernels 1.3 and 1.4, it was all the same until i tried reflashing without wiping battery stats. For the record, i flashed the new TK-Rom V 0.6 with the EternityProject Kernel 1.4.

[Q]Android-system 29% of Battery JVQ

Hi,
I recently updated my phone to JVQ but now i'm having a battery drain. The cause (i think) is the high percentage of the android-system. By now its 29% and that's alot. I already deleted the programe software-updater so that can't be the trouble maker anymore. Does someone has a fix for this?
Greetings

Yeah....let your battery go completely dead, then try turning on to make sure its dead
Leave your phone off and then plug in charger until its full, then unplug and plug in again to make sure its full
Repeat these steps 2-3 times and it should be all fixed for you
Also....using titanium backup, freeze the program called "Samsung account" that's another culprit in the "battery drain crisis"

Is your phone rooted??
Sent from my GT-I9000 using XDA Premium App

Yes, using deodexed stock jvq rom and speedmod k15-t24. Using black background screen dimmed, and everything to make my battery life the best but it doesn't make it one day. So maybe there is a bug?

Try going back to stock froyo, and flashing cfroot kernel so your phone is rooted but not deodexed or any other mods, then repeat the cycle and see if it gets better that way.

Just flash froyo and then repeat the cycle so i don't need to stay a day or so on froyo?

You'll need to be on froyo for about a week or just over, just until you've repeated the cycle 2-3 times bud

[BUG] Battery Bug for Stock 4.2.2

THIS BUG CAN DO HARM TO YOUR BATTERY! BECAUSE YOU WILL NEVER KNOW WHEN THE BATTERY DRAINS!
As we all may encounter the battery bug after upgrading to .423 fw. When one restarts his phone, he has chances that the battery level of the phone rises (e.g., I turned off mine just now at 26% and turned it on showing 51%). This has been confirmed by many users in the forum, so I believe it is a firmware level bug of 4.2.2.
Is there any one willing to pay some time on fixing it? Coz this is a quite crucial bug for us, we dont know when will our phones automatically turn off! Thanks in advance
I believe its not a caliboration thing coz we also upgrade or wipe our devices before, and no such thing happened. I think its a firmware or kernel level bug. Does anyone who flashes a custom kernel also encounter the same problem?
It seems that Spanish FW is free from this bug.
http://forum.xda-developers.com/showthread.php?p=43261281
plz report your rom or base FW in the reply. Thanks.
[NEW EDIT]
It seems that I fix the bug. The battery jumps when the phone restarts, so I think there is something during boot which causes the issue. I delete the XZDualRecovery, and test the phone several times, and its fine!
Deleting XZDualRecovery might be a temporary fix, so you can choose what to do
[NEW EDIT 2]
someone reports that they dont encounter the bug and believes that its the calibration thing. i declare again that i DID the calibration and the issue was still there. for me, at least, deleting XZDualRecovery fixes the bug. plz report more details in the reply, like fw, root or not, recoveries. Thank you

I don't think there is a bug here.
Never happened to me,cause i did full wipe while flashing.
Maybe it happens only for users that didn't wiped everything.

There is no kernel for 4.2.2. DoomKernel supports fw before 423. Correct me if Im wrong. Also in LB and know not much about custom kernels.

yes this issue exist. it happened to me when i updated to this new 4.2.2 also i have black dots in camera and the back cover of my xperia z is not correctly glued. i hate sony right now

Oh, this actually happened to me once.

It also happened to me yesterday. I usually never turn off my phone, but yesterday I did it and found the battery went from 26% to 51% magically.

I have the exact same problem, went from 26% to 52% after reboot... Is this bug bad for our battery? If so, maybe I'm flashing back to 4.1.2.

hello all me too experienced the same problem but I successfully regained my battery life. Here is what I have done....
1)First I drained the battery fully until mobile gets switched off
2)Then I left the mobile to cool off for half an hour
3)After that I charged the battery upto 100%
4)Following this I switched on the Mobile and did the battery calibration by using 'Battery Calibration' app
5)Again I fully drained the battery and charged it again to 100%
Now the battery life seems good. I checked this by using WiFi whole night....battery lasted overs 12hrs

This is exactly what I concern. I dont know when my phone is going to off, and it could be big trouble when there is no access to the charger.

Maybe we just need to recalibrate, drain battery to 0% and fully charge it to 100% while the phone is turned off.

plz give some feedback if it works

I experiencing the same issue. 2% to 55% after reboot. wow... 4.2.2 doesn't bring anything for me to consider to keep it. so back to 4.1.2 (.4.3.4)
But one thing for sure (never discharge a lithium ion / polymer battery from full to 0 they don't like it) you could do that with nickel cadmium/ metal hydride batteries ant they really thank for that if you keep doing that you just kill your battery before its due time.

Did it just start doing this? I actually noticed this happen from time to time on about every ROM I have tried, including CM10.2 which I am running now. But it's not all the time. Just a once or twice a month it seems. And it's usually happens when it hits about 40% or so, then drops like a rock to 15%. If it's happening a lot I would try booting back to stock or running a different ROM and see if it does it there as well. If so it could be an issue with the battery. You could also try installing BetterBatteryStats (it is free here on XDA) and see if that tells you anything.

thanks for the reply sir

Hi, I also get bad battery life when I'm on Cyanogenmod 10.1.3, but I got better battery life when I installed 10.2 although I also installed less apps. Have you checked BetterBatteryStats XDA edition yet? It tells you information about kernel wakelocks that could be draining your battery life and you may be able to use this info to fix problems in your phone to improve battery life. And of course when the battery meter reports 20-30% percent it will drop like a rock by 10% (I also experienced this in the Stock ROM from 4.0.4 and 4.1.2)
