I flashed an aosp ROM which was very unstable and so went back to the Sensation ROM I was using prior to the aosp ROM and all has been well since apart from a sudden drop in battery roughly 3 hours after flashing. I've attached a screen cap. of the battery usage screen shortly after it occurred, should it help anyone identify the problem.

I had the same problem just yesterday, it's due to the fact that when you're flashing your ROMS your battery got miscalibrated. It's a simple thing to fix just follow the instructions from this app on the Play Store (New Market for those of you without the update).
https://play.google.com/store/apps/details?id=com.nema.batterycalibration
Did you reboot the phone in this 3 hours? Coz I see this big step, which is happening when you reboot in recovery or flash something. You need to charge you phone and calibrate you battery

I rebooted after I'd configure the launcher as it was before I tried the aosp rom, but didn't enter recovery or flash anything.
I'll configure the battery and hope it doesn't happen, just wondering if anyone has an idea what caused it?
The exact thing happened to me. When you flashed your phone at a certain battery percentage (lets say 50%) Your new ROM assumes that 50% is the maximum capacity. Therefore, when you rebooted your phone it simply corrected the misreading. Calibrating your battery from the app I provided in my earlier post will delete the batter stats file in your phone and create a new one. Remember to use it when your battery is at 100%, then take your battery down to 0% and charge it back up to 100. I'm currently doing that process now after my phone jumped from 50% down to 20% after I rebooted yesterday.

It`s happening some times, you are not first and not last. Just calibrate you battery and will be fine. Good luck
Ok so I've downloaded the battery calibration app and currently charging my device however the app is displaying the same battery level as my phone.
Does this render the battery calibration a waste of time or is it to be expected?

Mine always does this when flashing and shows the sudden drop in battery. Once you charge it back up it should be fine again I'm sure. It always is for me
Sent from my GT-I9100 using XDA
Yep. You are 100% correct
Calibration apps do absolutely nothing except make you a few bucks poorer if you pay for them :-|
The best thing you can do is charge to 100%, pull the battery for a minute, and put it back in.
Also Ex Tweaks is capable of resetting the fuel gauge chip in genuine Samsung batteries should you be experiencing fuel alerted wakelocks on CM9 or similar.

Hi All,
I currently have an issue with my battery where it's draining rapidly i.e. 5% in an hour. I've tried calibrating 3 times, running void forever with golden leaf 18a kernel and using Franco battery optimization scripts. Also when I plug it on charger there is a 20% difference from what's reported i.e. on battery it says 60% but as soon as plugged into charger it says 80%.
Is it a faulty battery?

The method is in two process, steps 1-4 are ‘conditioning’, this allows the battery to make sure it’s absorbing as much juice as it can. The remaining steps are ‘calibration’ steps which work by re-writing the battery stats file on the device.
The Method
Run down your device’s battery until it turns itself off
Turn it back on and wait for it to turn off again; this may be straight away of after a few minutes
Remove the battery for at least 20 seconds
Replace the battery and charge until full and then for at least another hour – while the device is off
Delete you batterystats.bin file using one of 3 methods (requires root): Terminal Emulator – type su then press enter, next type ‘rm /data/system/batterystats.bin’ (without quotes). Using a Battery Calibration App (from market) – there are many choices available, they just delete your batterystats.bin file. In market, search for battery calibration. Make sure to read review and provided info in case of device incompatibilities. Manually – if for any reason the previous two methods didn’t work you may want to try deleting the file manually. Using a file manager with root access (such as Root Explorer) navigate to ‘data/system/batterystats.bin’. Delete ‘batterystats.bin’
Your device will now creates itself a new batterystats.bin file with a correct 100% battery reading.
Run down the battery until it turns itself off
Turn on the device and charge for at least 8 hours
Unplug the device, turn off and charge for another hour
Unplug the device, turn on and wait for 2 minutes
Turn off and charge for another hour
Use the device as normal!
You really only need to do this very few months or when you change ROM. Providing you don’d change any major settings the battery stats file will remain accurate.
Thanks!

take a look in Spare Parts app or *#*#4636#*#* (battery history) what's drain your battery. Yesterday i found that Camera 360 use sensors 13hours...
as the title says. I am looking for ways to get my battery to perform like it did before.
I was using villain rom with SPEEDMOD kernel.and I had very good battery life. one night I noticed my battery getting really really hot while charging. then the battery life went down hill. I tried wiping battery stats, removed battery for 5min after full charge, changed to cm based rom(it was even worse). i upgraded my modem to KI4. Now I am in villain rom with SPEEDMOD, (17) kernel and the battery life is still ****.
any suggestions####. yes I could blame Android os bug. its a 2.3.5 rom and I turned off all the sync as well I have absolutely no idea how to solve this issue.

it is with minimal use. theme is not the culprit as I have tested without theme and got a similar results.

I did not want to change the ROM but I gave 'HyperDroid-Androidmeda' a try. to my surprise the battery drain was gone. then i installed ics theme 'the battery was still good'. then I set up google account and restored K9 mail via titanium backup. THEN AGAIN the BATTERY started to deain heavily.i uninstalled K9,but the battery drain had not gone, uninstalled titanium backup no LUCK. still investigating......but i know i am close
The batteries used in the SGS2 do not need (and therefor not offer) calibration.
Your problem is something else and there is about a million threads about how find'n'fix the issue.
Out of the blue, I'd blame some app you're running.

I am aware of all the other threads. I've faced battery life problems before as well but it was usually resolved by flashing a different kernel or rom. you may be right about the rouge application.

can anybody help me make sense of what is killing my battery. btw I did ude the audio recording software for an hour and also the circuits app but they are not the culprit. main problem is that the phone does not go to sleep.... and battery drains rapidly.
i for first 50% of charge i was on speed mod kernel ... there was battery drain. and then i flased the rom again, the battery life got worse.

UPDATE....wifi was preventing my phone from going to sleep(still dont know what the real cause is)..... AFTER several ROMS and a DEAD SD card... my problem seem to be gone...for now at least. i basically flashed official firmware and flashed speedmod for root and clockwork mod. then flashed checkROM with speedmod again. fingers crossed the problem is gone.
I was always happy with my battery, but always wanted to find ways to improve it. I installed foxhound use black wallpaper and battery was even better after this, until...
I read about recalibrating your battery after installing custom ROMs and decided to try "Battery Calibration" App by NeMa.
Today for the first time ever my battery died whilst I was at work, I actually though my phone had broke as I was fully charged this morning and had rarely used my phone. My phone is on charge now and I'm trying to fix this huge battery drain, according to the battery settings the Android OS has drained 71% of the battery, that can't be right can it?
BTW I'm using and have always used stock kernel.
Here are some pics...

Don't let your battery drain to zero, charge from 20% it will train up again, and I guess this app just deleted your batt stats file and possibly wiped your dalvik. If you really wanna look at your battery get better battery stats from play store
Sent from my GT-I9300 using Tapatalk 2
Battery recalibrates itself after a week or so of use .
Wiping the battery stats does nothing and is just a stupid idea that gets posted by those that don't know the facts .

I didn't know this, and I assumed that people who make these app's or post about these know a little something about it, I've obviously received some bad advice on various threads.
So how can I fix this now? Judging by your post, I simply just using the phone for a week or so and it will fix itself?
Thanks for your advice,

For anyone interested or in the same situation, my battery is as good or better than ever. I just charged my phone turned it off charged again until full (about 5 mins) turned back on and just used my phone. Phone has been running for over 22 hours now and battery is still at 40%
Much happier now
Thanks to everyone for the help

Hi guys,
I badly need some helping hand on my device. Here is the scenario.
Im currently on Omega LS8 version with its default PHilz kernel when a weird thing happened on my SGS2.
After installing muzy (instagram like software) the phone begins to lose its power with 50% charge left. LCD flickers and suddenly blackout. I thought it was just deadbatt so I recharged back again my phone. After gaining 80% I turned on the phone and keeps on bootlooping. What I did is restore my backup. To my surprise it also keeps on bootlooping. What I did is change and clean the kernel and do fresh installation. It did boot and I think its ok now. I clean kernel again and change to Siyah 6.5. I tried restoring my backup it did restored, but after sometime the LCD flicker again and blackout again even on 90% charge, so I charged it again to 100%. After booting up it looks fine but when I restarted the phone on 90% charge when it rebooted it suddenly drops to 1% batt charge. I charged it again to 100% now with the phone on. After reaching 100% I observed the phone and use it normally, after using it for some hours, playing, viewing surfing. The battery drops at the normal rate without that sudden blackout. I cant seem to figure out what is going on.
My assumption is that maybe my battery is already damage that cause the sudden blackout, but if it does why during my observation it doesnt blackout and drops normally as before. What am I missing here is there someone who experienced the same? I doubt its ROM or Kernel related.???
Thanks in advance
Post your battery details, maybe fuel gauge went crazy.
Start thinking about getting a new battery tho.

Here is the screenshot. See the cut in the right side that is the sudden blackout. Would that be already a sign o damage battery?

Heres another screenshot after a sudden blackout again.
Did you try to recalibrate your battery? Charge it to 100%, unplug, pull your battery, put it in again and charge it to 100% again.
You probably did this already, but you didn't mention it. If that doesn't help, then my guess is that you need a new battery.
Ya sorry I forgot to mention that but I did recalibrate it so many times. Then I guess this is faulty battery. Any same issue are welcome. Thanks

please install bbs and upload the log
Logcat might be handy as well.
Ok attached is the logcat guys. Hope someone can interpret it

Probably so. Try to use a different battery for a full day and see if this issue stops. Make sure that your battery is authentic Samsung made, and that it isn't swollen or damaged.

It looks to me like your battery needs proper calibration, or maybe the battery stats file was not wipe off, and try using another battery as it may be the battery itself giving problems~
Are others having this? i mean i go through a full battery about twice a day.... I cant figure out what is draining it so bad. i have used WLD, greenify, and bootmanager to try to figure it out..... None of my apps are ever on the battery list, and screen is around 50% usually with android system and android OS always being up the list. I always thought it was my bad signal strength at work but i had two weeks off and my phone NEVER lasted even close to a day.
I have factory reset once but loaded my same apps backup.
I heard someone else mention that the sprint has this weird battery drain that is explainable and was wondering if others see that also.
I am on the search for a 6000+ mah battery i know it will have a replacement back plate but i don't want the whole case thing like the 9000 zero lemon.
Sounds like kernel wakelock
As of the last two days i have also been experiencing much faster battery drain. Have had the phone since launch and never had this problem.
I do not use the device in excess. Very few if any phone calls per day, some texting and gmail, occasional skim of xda, huffpo, phandroid apps and very light Twitter use if bored and not near the computer.
Battery has dipped 5% since writing this post...that's all of 1-2 minutes in use.
Sent from my LGLS990 using XDA Free mobile app
That's not normal for a Sprint LG G3. A couple of questions:
Have you looked at the battery stats page to see what app(s) are using the most battery? I'd suggest taking a screen shot of that page and posting it here.
Have you tried rebooting the phone? If there's an app or process running out of control that will often clear it up.
Are you rooted? If so, install better battery stats so we can get a better look at what's eating the battery.
Finally, you might want to take a look at this thread: http://forums.androidcentral.com/sa...android-system-eating-your-battery-check.html
While it's unlikely you have the same problem I did, the tools and techniques I used to debug it might be useful for you.
Gonna wait for some custom roms to see if the problem just goes away.

Dude the battery app should show you what is causing it. Something has gone rouge!!! I just had my weather app running in the background using GPS for 5 hours, yeah my battery went way down. Freeze some BS apps. I routinely get 30 hrs plus on a single charge. Not the phone itself something you are using is causingi it.
As requested, my craptastic battery info. Brightness was 83.
