after using my mobile for few minutes, my battery % reduces , but when i get into recovery page it shows the correct % of my battery and when i do the battery stat wipe, my % in mobile turns back to normal....and its not the rom problem, cause am facing it in all roms.
how to get rid of this thing or any way to wipe the battery stat in the rom itself?
s there any one 2 help me with this?
Did you try to recalibrate battery??:laugh:
Did this shown on ur main ROM notification or it is from an app or widget?

what you mean by recalibrating the battery???
and then yes i am talking about my main rom, i dont use any aps..
Try to test ur battery durability. It could be there is a lack power consumption of ur battery.
U can test it by using an app that show the status of ur battery health like this attachment.

If the indication shows as 'bad' I suggest to change ur battery.
Or just simply try another battery and find the difference.

To calibrate the battery the first step is to ensure complete draining of your smartphone until it turns off automatically. You must make sure that the phone is so discharge may not be able to turn on (if it turns on, it must turn off immediately to the boot screen) Now put the device in charge, wait is charged to 100% and leave it connected for another two hours. But do not keep it too long in office after unplug the phone from the office.
Now remove the battery from the phone for 10-15 minutes and then put it back in its slot.
When the operation is completed, put back in charge the phone and wait a few minutes (5-10 minutes) after you turn on your smartphone, wait until it is started and disconnect the terminal from the battery charger.

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...
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?

i thought a manual battery calibration on a i9100 is a waste of time . They didnt calculate it like HTC does. Somebody explained me that this mobile got another System for that but i just forgot what for...
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.

charge ur phone to 100% then try resetting the Fuel gauge chip in extweaks then reboot ur phone and wait for a cpl of hrs then ur batt starts showing near correct %
Full batt charging and reboot is not necessary. Simply go to ExTweaks, reset fuel gauge chip and wait few hours. Your battery percentage will increase.

I am having the same problem but apparently Extweaks doesn't work with my kernel.
Is there another solution?

Charge your phone untill you're sure that it reached 100%. Turn of your phone, remove the battery for a minute, put it back in and reboot your phone again.

I've been experiencing the same problem with my SGS2's battery and noticed that it is getting bloated. I purchased a new one to prevent severe damage on my mobile phone.

Hi all, as the description says it's quite weird. While I have let's say 56% battery and for some reason I restart the phone, then suddenly after booting it show I have 18%!!! (screenshot attached)

I have latest 4.0.4 official UK unbranded firmware and it happened on 4.0.3 too. I have tried factory reset and doing a battery cycle.
Could it be a pure battery problem or may it be a bug? Anyone else has this problem?

I also have this problem... It's a huge issue for me! Constantly having to recharge! grrrrrr!

Have you tried recharging to 100%, taking battery out for at least 3 mins (180 secs), then allowing full discharge?

Yep tried that. Tried anything I can think of.
Yes I have tried all those battery tips in general...even tried to leave the battery disconnected from the phone for one night after doing a full discharge and them charge with the device turned off.

It's normal. The fuel guage chip in GSII doesn't need calibration, but the downside is sometimes after rebooting below 60-50% battery it can show wrong battery info.The battery still has power just reporting is wrong. If you wait for sometime you'll see the battery climbing back to pre reboot state.
So DON'T PANIC normal operation.
Restarting the phone resets the fuel gauge. If you leave it for a while, the battery will come back
Thanks for the replies!
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

Logcat might be handy as well.

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~
