Excuse me,my English is poor....The problem is this, after I brushed my i9100,I start charging it to 100%,.When unpluging the charger, the battery directly drop to 40%.I download a power correction software , following the instructions to correct.but,it doesn't work.Today I re-brush the Recovery, and wipe the battery information, reboot, it still not work. Oh,it makes me crazy!!!How can i deal with this problem???.....in the process of charging today (probably a total of 6,7 hours), i found it less than 30% charged then jump to 100% at once.the software show the battery voltage is about 19% 3720mv.Is my charger causing this problem? ? ? ?
I've read this problem days ago. Stay steady, don't have to afraid.
You can try to charge your device in switch off state. If it doesn't work, remove your battery for few minute, then put it back. Then try again

The phone was freshly charged overnight. I was using the internet while listening to music through (3rd party) headset and since the 3G signal in the building was kinda ****ty I switched the phone to EDGE (GSM only). Then I quit the Settings menu and opened Firefox, tried to load a web page and at this point the phone froze. I'm not sure if I restarted it or it restarted on itself but after the boot the battery was showing about 40% less. So I turned the phone off, pulled the battery, rebooted, same reading.
I used the phone for a while after that and now it's showing critically low battery and I'm wondering what should I do now?
Is it really so low on battery or the reading is wrong?
Can 40% battery disappear just like that and what could cause it?
Should I charge the battery or let it discharge until it turns off by itself?
Battery screenshot attached.
Perhaps a battery calibration issue caused due to the crash, my advice would be to drain the battery all the way down to zero and let the phone turn off, remove and reinsert battery and proceed to charge till full and then turn the phone on again. Hopefully issue should be a one-off and now resolved.

happend to me before on my htc desire hd..battery pulled and battery stats dropped down the gutter..just let the battery die and charge fully or even just charge it up to 100% from where u at now..doesnt matter it will fix itself...
My phone was doing the same thing, it was rebooting or shutting down two or three times a day, usually a few minutes after taking off of charge.
I have sent it back for a replacement.
Do not drain the battery to zero. There is not reason to go belox 10% charge, as you could damage the battery if going to 0. These are new batteries much smarter then old ones.
You don't need to drain to zero but it won't do any harm if you do. Probably a wee softwre glitch. Wouldn't get too worried about it.
a good option is battery doctor - its a free aplication from the market...
let your battery go down to 20% and then open the app in charging mode...let it charge(dont close the app during the charging process, just keep it open)...woallla.. u have made a full cycle charge - easy as that...
Yea, as the title says.
is there a way to fix this ?
THANKS!
I would try re-calibrating your battery. Try this which is straight from my MIUI guide.... (I suggest method 2 as it is the easiest)....
RECONDITION YOUR BATTERY
AFTER FLASHING IF YOU FIND THAT YOU HAVE BAD BATTERY LIFE TRY ONE OF THE METHODS BELOW TO FIX:
Method One:
Use phone till it dies on its own, completely dead.
Charge phone completely, plus 30 minutes longer.
Unplug phone from charger
Reconnect, you'll notice it's not full, charge till it is again.
This is bump charging and NOT something you want to do often, a few times is okay, in my opinion. You could skip the bump charge if you like.
Phone remains plugged in.
Boot into recovery (volumes + power)
Advanced > wipe battery stats, reboot.
Use phone till it's literally about to shut off (or does) Charge till full + Use phone like normal
OR
Method Two:
Download the Battery Calibration app by NeMa from the Android Market

Tell me if this works for you...
A real battery capped to charge at 96% or 97% due to voltage issues that would occur if charged to complete 100%. But samsungs stock ROMS and most other ROMS are customized to display this 100% when its really not at that level. Since MIUI is based off of CM7(and this is uncredited of course), it is not modified in any way and it displays the actual battery life. Which in your case is 96%. Hope this helps.

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.
Regards,
John.
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?

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.
First of all it wouldnt charge past 99%, And then, after one hour of standby it went down to 88%!!
Cm7 official stable release.
Me too no pass 99% :S
Try to download a "battery caliberation" app and do that, also burn it to 0% and charge to 100% while the phone is off..i heard that this might help.
Now i will flash Nottachtrix and do what i wrote Good luck man !

The charging thing is something that is (seemingly) well known throughout the community. I have tried to do the calibration, but it doesn't seem to work that well (at least for me). There is a thread around here somewhere for fixing the issue. I just have never tried it due to work reasons.
The charging past 99% is a known issue with most of the ROMs. There is a thread in here that takes you step by step to get it to display 100%. Basically....
Charge the phone long enough to where you know it should be at 100% even though it is still displaying 99%.
Power the phone off while it is still connected to the charger and then pull the battery.
With the battery pulled, power the phone back on until you see the battery indicator with the "?".
Put the battery back in and reboot.
You will then see the display of 100% with the phone still connected to the charger. The only downside is that as soon as you disconnect the charger, it will drop back to 99%. I have done this multiple times.

I read good things about it.
First of all, use Wipe Battery Stats function at recovery.
1 - Discharge all your smartphone battery;
2 - Connect it to the wall charger and don't turn it on;
3 - Wait till it shows you 100%;
4 - Remove the battery, wait 10 seconds, put it again and keep it turned off;
5 - Wait 30 minutes, keep it connected to the wall charger and press power button till it turns on;
6 - Wait 30 minutes, keep it connected to the wall charger and use Battery Calibration App to calibrate it;
It doesn't make any sense, but sometimes, after step 5, i prefer connect it to usb port in a laptop or computer and wait one hour. It always worked with me.
It might solve your problem .
Wiping battery stats does nothing. it just takes a few charge cycles. If it's a new rom and it's draining fast it's also cause you are probably playing with it a lot

It could be a bluesleep problem... Install CPU Spy App and look if it goes into deep sleep mode. If not, there is a fix for it.
Aside from the OP's issue with the battery draining quickly, why does it matter if it doesn't show 100%?
Nothing can ever 'really' be 100% charged because as soon as you take it off mains it is instantly on the battery at lets say 99.9999%...
As long as the battery doesn't drain quickly I couldn't care less if its showing 99 or 100%.
The problem was that it was draining very quickly to smt like 50% and then it would hold longer...I just wiped everything, restored a neutrino 2.7 nandroid backup i had, flashed the jug fix v2 and now it shows 100%
Hi as stated my question is NOT to know how many of you experience charging that takes too long, but is there a SOLUTION for it?
I am using a desire s, it used to take 2hours 30min(from 15%-100%) but now a days it takes close to 5 hours to fully charge.
I've read many thread with similar problem but non seem to be able to find the solution.
I doubt it is battery related issue as i got this phone together with my friends and theirs has no issue like this.
I've tried :
1)full wipe
2)different rom(s)
3)different kernel
4)battery stat wipe
5)different charger(both are htc)
ps : I've post this in DesireS Q&A but did not get any solution.
How are you charging your phone: USB to PC it via wall charger? If it's taking longer than usual turn off the phone. I've found that this sped up the charge dramatically! By doing so, you can also see a battery simulation on the screen showing the charging process.
Also, if you're charging vis USB, the requirements are 5 volts from a USB connector. But the problem is amperage. Wall chargers can supply up to 1 amp (some will supply more, but you don't want more for a phone), while many computers will only supply 500 milliamps out of a USB connector. Thus the phone (battery) will charge faster with a higher amperage. If that doesn't do any good, you may have a bunk battery or some kind of hardware issue...

I am using wall charger. It seems consistent to charge slower at around 70% then speed back up at 90%. Are u sure that this is a symptoms of a spoiled battery?
To me(an accountant not a technicians) it seems like the "smart" phone is tell it to charge slower at 70%.

Same problem
I have the same problem, first when I bought my SE x10 mini pro. It charged in 1.5 hours but nw it takes about 3 hours. I don't know the reason but I'm trying to find out how to solve this problem.
I'm not entirely certain its a case of bad battery, but it does sound a bit suspicious. If you're feeling up to it, you can try this: (it's worth a shot.)
If, after rooting or more likely that case after flashing a new rom, you often have battery reporting errors and re-calibrating the battery along with some steps I will outline for you below will ensure that your battery is getting a full charge, and the battery reporting accuracy is right on.
1. Take the case off your phone (one of the latter steps involves taking the battery out from the phone while it's plugged in. Make sure your case won't stand in the way.)
2. Install Battery Calibration app from the market
3. Plug in your phone to charge while it's on, wait till it gets to a 100%
4. When the charge is 100%, open the BatteryCalibration app and lookup what the charge is in MV while at 100%. Write it down.
My Atrix 2 was showing ~3400MV while at 100%, which is definitely not the maximum capacity.
5. Discharge your phone completely until it shuts off.
A good way of doing this quickly is by turning on wifi, and a video player.
6. Without turning on the phone plug it into a wall charger and let it get to 100%
7. When it's at 100%, without unplugging it from the wall charger, take off the battery cover, and take the battery out.
Your phone will "reboot" and show a Missing Battery icon.
8. Without unplugging the phone from the wall charger or turning it on, put the battery back in and wait until the phone recognizes the battery.
9. Your battery should now be recognized by the phone, and showing a charge % significantly lower than 100%.
Mine showed only 5%.
10. Let it sit there charging for 2-3 hours (or more).
My phone wouldn't charge past 10%, but yours might. The numbers don't matter much as the phone is definitely getting additional charge that could have been lost while flashing ROMs, etc.
11. After 2-3 hours (or more), turn the phone on while holding the volume down button and get into CWM.
Do not disconnect it from the charger still!
12. Wipe battery stats and reboot.
Do not disconnect it from the charger still!
13. When the phone turns on, go into Battery Calibration app again and look up your MV numbers -if you were like me, they should be significantly higher than before. After this whole process I had 4351MV at 100%, comparing to 3400MV before calibration.
Do not disconnect it from the charger still!
14. Make sure your wifi and data connections are off. Now finally unplug the phone from the charger.
Go to bed, let your phone sleep too.
The next morning, use your phone as normal throughout the day. Then when it comes time to charge again, see if that does anything for your battery life and/or charging times...

best way is shut down device when charging

Yes is charges quickly when the phone is off, but what if i am expecting a call or some sort. Could it be a script some where to tell the phone when should it start slow charge or something similar?
