When I restart my phone, either using the power button or a battery pull, my phone will always restart with 31% battery remaining. It just did it with a fully charged battery that was plugged in for 9 hours. Now I have to charge it all over again.
Can you guys restart your phone and see if it happens to you?
If not I'll try a factory reset and if that doesn't help I'll have to swap for a new phone.
Thanks
Factory restore seems to have fixed this.

New gTablet, just use only 1 day, the charging allway in 96%!!! never go upto 100%, is this normal?
Pls: i see 97% about 5 minute ago, but now back to 96%,,,,,,
thanks
Yes, it's normal, everybody has inaccurate battery readings on Gtablets.
To try to fix it, you can drain the battery all the way down, then turn it on a couple times ot make sure that it's completely drained. Then, plug in the charger, turn it on in recovery mode (assuming that you have CWM installed) then wipe the battery stats. Reboot, and charge it all the way back up. it may charge to 100%.
Mine has a different issue, it will charge to 100%, then it will stay there for an extended period of time. 3 hours later, it might still be on 100%, but I know that it's not. If I let it drain down, it will actually turn itself off around 13% - 15%, so my battery calibration is off by that much in the positive. The first time I wiped stats, it fixed it, but it's slowly crawling back up again.
thank . TJEvans, ithink i need to return back. so many problem with my gtablet.
I recently dropped my S2 into water for a few seconds and following a week of drying out I turned it on to find that everything is working fine. The only problem I have is that the phone thinks it is at 100% charge after being plugged in for a few seconds. On the first charge I left it plugged in whilst showing 100% and overnight it managed to charge fully so that the phone worked for a full day.
Today however, it reaches 100% (after a few seconds) and seems to stop charging any further. I can use the phone whilst it is plugged in but as soon as I unplug it shuts down due to no power.
Is there a way to reset the battery stats or fix this? I'm currently running 2.3.4 stock.
Thanks in advance,
Chris
Reset battery stats .
As you dont know the basics try Battery Calibration from the market .

That requires root access... is there no way to address this without deviating from official firmware?
Try pull out the battery and put it in the hot water cupboard overnight (or blow dry it, but not too hot - it is a battery afterall), then try it again. Could be related to the calibration chip on the battery...
Battery calibration
It has been mentioned in several XDA forums that the SGS2 has a power supervisor chip that manages calibration automatically and doesn't need battery cycling.
You have probably sustained damage to your phone. It wont cost much to try a new battery though but it is a long shot.

I'm guessing it's a hardware fault with the charging circuit. I don't suppose anyone can recommend a good repair shop in the UK?
Hi, I am sorry I am using your thread to post a personal question.
I would recommend you to try a different battery though.
The problem I have is similar, but not the same.
When the phone sounds that it has full charged, I unpluged it and it immeadiately changes from 100% to 99% or 98%. After that it uncharges as normal.
What could be the reason?
I calibrated it with the battery calibrator. Also took out the battery after full charge and plug it back on. With no results.
What could I do?

You could have searched and read all the posts that say this is normal behaviour .

For anyone who's interested, I've managed to fix the problem by doing a full factory reset. To do this I powered up the phone into recovery mode (start whilst holding power, home and volume up) and performed both factory reset and and cleared the cache. Now appears to working fine.
Thanks for all the suggestions.
hi guys. i've just flash a new miui rom on my o2x. and i found that the battery drain much faster than it was before. last night i had 14% of battery left on my phone, and this morning it shut down due to out of battery. so i pluged in my wall charger while my phone was off. and when it showed the green fully chargeed bar i disconnected the charger and boot my phone in to CWM recovery to wipe battery stats. then i reboot the phone into android and u know what? the phone show 100% of battery only in 3 secconds and then it show 1% left, please connect the charger. huh? what the f*** is going on? i connect the charger and the phone show that it's being charged? how can it charge a fully charged battery? and the charging speed is faster as light. it's has been charging about 15 mins now and it show 46% charged. may be google was wrong saying that batterystats.bin does not affect the measurement of battery level.
Seems to be a bug issue.
What i would do is reinstall the rom.
Wipe data, wipe cache, and wipe dalvik cache.
Make sure you wipe both at least 3 times then reinstall because sometime android doesnt get everything the first time.
If still fails flash a custom kernel.
These help adjust the phones hardware to correspond with the settings of your software.
good luck to you.
Hey there,
hope you guys can help me out on this:
For about 3 weeks, my battery is going crazy. The statistics won't reset even after a 100% charge (see picture). Battery seems to drain way too fast. Sometimes, charging will get stuck at 66% or something (unplugging + plug back in doesn't help). Or it will jump from 89% to 100%, and will remain at 100% when the charger is unplugged, but jump back to 89% after a reboot.
Long story short: I think I need to reset something here. But I'm not entirely sure what else to try. I've erased the batterystats.bin using the Battery Calibration app multiple times. I've tried to do a battery wipe in recovery mode, but my CWM doesn't show that option. I've done several 100% to 0% to 100% complete charge cycles. Even bought a new battery. Without any effect. Kind of clueless
Running Cyanogen 10.2 on Galaxy S2
Glad for any help!! Thanks!

Hey everyone. I'm having an issue with the battery stats of my Acer Liquid Z500.
When I charge my phone, sometimes the battery stat freezes at some point, 35%, 28%, 45% for example, for some time. When the phone feels like it's discharging, the battery stats come down really fast, like 1% per 15 seconds, until it's off.
I've tried booting into recovery mode and checking if there's any option to wipe battery stats, but there's not.
I've tried factory resetting the phone but it doesn't work.
I was wondering if you guys could enlighten me about this issue. It's getting really annoying.

Had the same problem once on a different phone. What I did to solve this was quite simple: after battery percentage has frozen, I shut off my phone completely, so it can charge without interference. So just wait until the phone has charged completely. Another option would be to perform a simple reboot after the freeze.
If this doesn't work, maybe you have to re-adjust your battery by charging it to 100% and then let it discharge to 0% and then do a full charge afterwards.
