Hello. I've been charging my phone the whole night and it only got to 94%. After I restarted the phone, the battery was at 81%. Does anyone knows what's wrong? Thanks.

A little more info would be nice. What rom are you using? Do you have root permissions? Are you s-off?
The first solution is:
On OVO 3D sometime if battery is charged to 100% he starts to use battery power instead of charger so if the light is green you need just to connect the charger again and it will start to charge again.
And the second:
After you installed some kind of ROM you need to calibrate the battery again. You can do by discharging your phone to 3-5% and then charge it to the full. You need to repeat this process few time and then you have calibrated battery.
Sorry but i forget to say that before recharging you need to delete old Battery stats

The first thing is correct. When the phone is fully charged the charging stops and the phone uses power from the battery.
As for your second statement - you are partly right. Even though most developers say the same thing you said I found the battery calibration is the best way to get the most from your battery. I tried everything that developers suggested and it didn´t work so well. Battery calibration did the trick - now my battery life is great
Anker batteries seem to work the best
Hey. Thanks for the replies. I'm using the 4EXT recovery and KingCobra3D - ICS 1.6 ROM. The thing is that my phone doesn't even charge up to 100%. Is it necessary to discharge the phone to 1-5% and then charge it to full and then calibrate via recovery or can I just calibrate the battery without having to discharge it first?
Also, I have root on my phone and S-ON.
My anker battery has reported like 4000 charge since I got it and I tried using the calibrate app but it still reports the same after a few cycles? It should be reporting 1900.

If you don´t use battery calibration you should go into recovery and wipe battery stats. Then boot up and fully charge the phone and let it discharge to 5-15%. Charge it to full and that should be it.
If you use battery calibration just charge to full, enter calibration app, hit calibrate and that is it

Okay the phone charged up to 100% but it took ages. I've downloaded the Battery Calibration app from the Market and hopefully everything's gonna be well now.
I have battery life issue too. I will try battery calibration.

Hi everyone,
Im running cherryblur 1.4d obviously rooted and unlocked. I've been running it like this for over a month now and its been great but a week ago my phone stopped charging up to 100% when I let it charge overnight. It reaches 90% and stops. I have a charger that charges the phone and an extra battery at the same time and it has worked great since I got it and the only way to get the batteries to go to 100 is to take the batteries out of the phone and put 5hem to charge in the battery slot. Please help me guys. Its not the battery because I have another battery and it won't charge fully either. I'm going crazy with this I've looked everywhere and haven't found anything
Charge your phone to its fullest capacity (I guess that would be ~90 for you)
Wipe battery stats in recovery, reboot.
Let the battery drain completely, until the atrix shuts off. Watch a bunch of videos or something.
Recharge back to full capacity, hopefully 100%

You might also want to try charging the battery with the phone switched off, when it reaches 100% remove the battery and wait for the no battery icon to appear on the screen. Then re-insert the battery and leave to charge for another hour or so.
After doing this, boot into CWM and clear the battery stats. This should fix your problem.

Mine won't charge to full unless I'm using the charger that came with it, ALL other chargers stop at 95-98%.
Sent from my MB860 using XDA App
Make sure the other chargers are kicking out at least 700ma the moto charger kicks out 850ma.
Any less than 700ma and you'll not get a full charge, a lot of 3rd party chargers only 500ma which will not work too well.

^ This. Most people don't realize that they can't use just any charger with some phones, this phone being one of them. It requires a certain amount of juice running through it to charge properly, which is why if it's dead it won't charge from a USB port.

Thank you guys I'm in the process of trying the first suggestion I'll see if it charges fully tonight
Also if you are swapping batteries, the battery stats will continuously get messed up. It will be trying to configure the two as one and that could make this a reoccurring problem for you
Sent from my MB860 using XDA App
Oh that could be it as well because the second battery I got drains quickly (or it shows that way) and spends the other half of the battery life (8~10hrs) at 1%
Ok guys turning it off and charging fully and then unplugging and plugging again, and wiping battery stats after worked perfectly. Thank you!
For anyone who has this problem you can wipe battery stats with the battery calibrator program or in CWM and then you must drain the battery after wiping the stats.
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.

Hi folks,
my Xperia Active shuts down at 25-30%. I tried to calibrate, but occurs after few full-charges again. phone is rooted, using latest stock ROM 2.3.4. Any ideas? I mean if you have an experience with it - gimme any hints / step-by-step advises. THX many times!!!
I would try to delate battery cache,discharge it few times and format it.i have had this same problem but after them few steps my batt work normaly.What i think your battery was not formated properly on the very start of using it.

calibrate - full charge and remove the battery charge info file
format - full discharge batter, turn phone off, full charge and than turn phone on?

If you've tried calibrating the battery and thats not work it might be that the batterys faulty. Try a different battery and see if that works.

the battery MUST be ok, as it is only 2.5 months in use in the phone. It worked and after I re-flashed the standard ROM, it worked a few charges and now it went crazy. the Battery Monitor Widget is not able to detect the battery capacity (mAh) and when charging, it indicated 100% at almost 4.00 V, where it shall be 4.2V as 100%.
I will completely discharge the phone, and when it shuts down, will put it to the charger, turn it on, calibrate - erase the battery info, unplug, discharge untill it will completely turn off, charge it with phone being OFF and the, after it will be completely fully charged, turn it on.
will see where the rabbit hole goes...
tlsty
After flashing darkyrom, I messed up my battery stats (I think) by calibrating it everytime I fully charged my phne. I know I what I did is stupid not reading infos about it. But just to ask, if flashing to stock firmware will fix the battery drain. Everytime i full charge to 100% and rebooted the phone, I get 22% and figured that android OS is consuming 75% of my battery. I'm pretty hesistant flashing it because of battery drain that might turn off the phone during flashing. It has no warrant already so I cannot bring it to samsung. So is it safe to flash the phone?
Just plug your phone in your computer or wall to make sure the battery doesn't die.
Drain batt completly and then charge via pc usb untill full, unplug drain and charge via pc usb again. Pc usb has 500 miliamps, so will charge slower but will have a more full charge.

Your right, your phone doesnt charge while in recovery or while flashing. If you have clock work mod recovery then charge your phone via pc to full, then reboot to clockwork and select wipe battery stats. Reboot your phone and use untill it is 10% then do a pc charge untill full. No need to flash now, try my way first.

Will this get rid off the high android OS/cpu usage? I want to flash it to stock ICS btw.
I think so, i dont think it is your android taking all the power, I dont know much about android and kernels and stuff, but i know allot about batteries since i am an rc driver and flyer. Your ac charger has to much current so the phone reads top voltage for a few minuts and assumes that the battery is full, when in actual fact only about 400 miliamps went into the battery and the battery capacity is around 1500 miliamp. Now if you charge at lower amp level the voltage wont go to the top right away. You should be able to get a full charge after about 4 charging sessions. I would not suggest trying to flash now with your weak battery.

I messed up with the battery calibrator I calibrate everytime i fully charged my phone so maybe this is the cause. I will try your suggestion and see if it works. Thank you for your help.
The battety calibration tool is supposed to wipe your battery stats like clockwork does, maybe the app has some issue and is not wiping the stats completely. Use clockwork recovery to wipe the stats once the battery is fully charged. Then again only when you flash a new rom or put new battery.

And one more thing I noticed, the phone gets full charge so quick. Like for 30mns, it's 100% already. When before, the phone gets fully charged for like 2-3hrs.

It sometimes happens.. Did u charge from <20% or greater than that?? Becoz sometimes the battery shows fake stats.. The best way to calibrate is LEAVE the battery to calibrate itself for a week times. It needs a cycles of charge and discharge to get the correct value..
And the battery usage is not changing already. Been 4d 36mns 24 secs for a week. I wanna flash a stock rom but afraid battery will drain during flashing. *sigh*
Get a wall charger to charge the battery, check that the battery is not damaged ................................ . regards
It may be possible that you have a dead cell. Charge the bat to full, remove bat and use multimeter to test the bat, should read about 4volts. Leave the battery one side for about 1.5 hours, then test the voltage again. If less then 3.7 then you have a dead cell and will have to get new battery.

What multimeter? Got no idea what it is. Is that an app?
No its not an app. Its a tester that an electician would use to test voltage. Go to android market and download Battery info. That is an app that will also tell the voltage. Currently my bat is at 62% and 3.8volts. Download the app and let me know what the reading are.

What about this part 'leave the battery one side for 1.5h' you mean detach the battery of phone for 1.5? And what if I got 4below volts, that means my battery is okay and its the battery stats messing up?
Find an electrical tester, most car parts shops have the cheap ons (they do the job)
Full charge battery and remove battery from phone. On the battery there should be 3 copperplates, find the two with + and -. Test voltage on these points with tester set to dc volts. Leave your battery out of the phone for 60minuts and then test again. Let me know what the results are.
Sent from my Sensation Z710e
Fully charged battery should be 4volts for about 30 minuts and then start dropping to about 3.7. If less then 3.7volts your battery is faulty. Any voltage between 3.7 and 4.0 volts after one hour is 100% fine.

To tell you the truth, the galaxy s2 is my friend's s phone so as soon as i get it, i will test it. But now, i'm using galaxy s but I think i have a faulty battery. I will try what you said and it helped me a lot so thank you!
most people here are changing ROMs...and most of the time people say that some ROMS are a big battery drainer..
some move to other ROMs because they noticed that the battery performance of the ROM they are using is changing..
this happens because all the records on the way we charge are saved on the battery stats..sometimes our battery meter says the wrong information. that is why we have to calibrate our battery...we usually do this by going to CWM and wipe battery stats..
but are we really doing it the right way?
here is my guide to do this in the proper way:
i know some of you are using battery calibration from them the market, but all it does is just delete battery_stats.bin from system..But the truth is, the system is still writing the old battery stats if it's erased online...So the only solution is to delete it through recovery...
this is what you need to do:
1.Install Battery Monitor Widget from Market for Monitoring
2.Charge your phone to 100%
3.When done, restart your phone, but go to CWM recovery
4.Go to advanced -> Delete Battery Stats
5.Reboot, you should get battery about 90-100% (depending how much margin has been wrongly calculated)
6.Open Battery Monitor Widget to monitor the voltages. the maximum voltage is 4200mV for Li-Poly battery. Try to reach that value before disconnecting the charger.
7.Before the voltage graph getting dropped, Disconnect the charger immediately. for me it is stopped at max 4190. your mileage may vary.
8.You're done, your battery is calibrated..
kind regards,
baiclark

Guys!! Wipe battery stats is havent nothing to do with battery life!! There is only info about battery drain of every app and time of theses app. Also battery stats are wipe every time when you charge battery above 90% so this function in cwm is practicaly useless.
