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.

But i will have to flash it via odin so i cant charge it while flashing.
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.

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.

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.
So I charge my Galaxy S2 to full (or at least, it says it's full), unplug it, and it says it's only charged to 60%, or 43%, or something random. I plug it back in, and off it goes, starts charging again, this time usually up to the "proper" 100%.
On top of this, the battery drain is very fast (10-15% overnight)
So, believing it's the battery, I get a replacement. Same thing.
I then learn that the reason might be because I flashed Lite'ning ROM while not on full battery, and that it just needs a battery calibration.
Ok, so I do a battery calibration - I charge it to full, drain it to 0%, then charge again. Take it off the charger, plug it back in to make sure it's full and...what do you know, the battery meter shows it at about 20% It continues to charge for about 4-6 hours after this.
Help? Is my phone faulty, or am I just not doing the calibration correct? I don't think it was like this before I installed Lite'ning ROM. So I'm praying it's not the phone itself?
The only other thing I can think that it might be, is the fact that it's a UK Galaxy S2, but I'm using it in Japan with a Japanese charger. Though I don't think that's an issue.
Any help would be very much appreciated.... not only does my battery not charge to full in one go, but it has **** life afterwards

Yeah, that's what I meant by "tried the battery calibration".
Charged to full, wiped battery stats from recovery, then rebooted.
Try using app battery monitor widget, and check battery is actually charging it to around 4200mV, and discharges to around 3500mV at approx 1%.
100% is not full, it will continue charging for quite a bit after to around 4200.
At least you will know that the high and low scale is correct, and can monitor in between.

So I charged it overnight via AC adapter (with the phone turned on), woke up, and the phone was at 4%!
Seriously, what the hell?
Phone was indeed reading close to 3500mV via Battery Monitor when it was almost empty
Any help?
Try charging via usb, much slower than ac though, then check again.
Don't drain battery to 0%, certain reports indicate not good for the battery, others say no worries. Try 1% so the phone doesn't turn off.
Although the huge jumps in battery level indicate a battery issue; If still no good, try a different ROM, and recalibrate. Also try in flight mode overnight and check results.

Thanks for the suggestions man, I appreciate it. My main concern is whether or not it is a problem with the phone itself - the place I bought it from has a ****ty returns policy and won't exchange it or anything. So I'm hoping like hell it is something I can fix myself (new battery, new charger, different rom, etc etc etc).
As I mentioned, I'm currently on the latest Lite'ning ROM with Ninphetamine kernal I believe. Just did a factory reset/data wipe via recovery mode, thinking it would get rid of lite'ning rom and the ninphetamine kernal, but upon rebooting the Lite'ning rom theme (blue lightning on the icons, etc) is still there.
Anyway, I have it charging on USB now, and I have ANOTHER battery coming tomorrow, along with a stand-alone wall charging unit (that charges just a battery on it's own, not connected to the phone). Maybe I should charge the new battery via that for 16 hours, then stick it in the phone, wipe the battery stats via recovery, and flash a new ROM (say, the new villainrom)?
Yeah, forgot about that also, I have two SGS2 (one in for repair), and each time new have let is charge overnight without turning on before first boot. Then discharge to approx 1% (do not let it die), then charge fully to 100% and approx 4200mV. Quickly clear battery stats with Battery Monitor Widget (menu / stats / SU permission, no need for recovery as you'll waste battery rebooting and get inaccurate reading) and immediately disconnect charging. A new batt stats file will be generated.
At least with this method you'll know your at a "true" 100%.
Also, it may take a number of charge cycles for full battery potential, but don't let it die.
I use Cognition straight "out of the box" with no issues.

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've read alot and tried many methods in the past, and one thing I am conviced is that you don't really have to drain your battery completely before cycling. The dev of 'Battery Doctor' app says you need to go below 20%. I can acheive pretty much the same effect if I start from just below 50%.
The key is to keep the charger plugged in after you get the green light. 20min is probablly right, although I tend to keep it longer because I usually go to sleep when I cycle batteries.
over charging lithium ions is not a good idea...also you do not need to cycle lithium ion batteries as they contain no memory as the old ni-metal hydrdie and ni-cd. batteries..
.infact is is advised to charge you batter often and keep electrons moving in your lith ion battery as oposed to ni-cd which is better to let it fully charge and fully discharge.
Do not over charge or fully discharge a lithium ion battery...infact the high voltage stresses the battery further and shortens its life. also do not discharge you battery fully as this is also not good for it...with lithium ions it is good to charge as often as possible, to prevent erosion inside the battery...while doing this you must not use the device...so even if you charge it for 10 minutes its a good thing for the battery. do not use the phone while charging as this confuses the battery.
here's a good article, that explains everything completely http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
From what I have read so far, wiping battery stats simply erases the information in the battery usage screen. I don't see it having any benefits to how long the battery lasts even in my previous attempts to increase battery life.

While I believe the information you posted is true, I think it may mislead some people here.
1. when you wipe the battery stats, you still need to do the cycling. Otherwise, your new stats will be off.
2. 'plugged in' doesn't mean 'constantly charging'. The IC chip on our phone is supposed to do what you are recommending we should do; charge to close to full, drain some, then charge to close to full. I say 'supposed to' because I only read about it somewhere.

You're righ that wiping battery stats won't improve your battery hardware-wise. But if done properly, wiping stats and cycling should re-align your phone's knowledge of the real battery capacity. If you have 100% at one time and 50% just an hour later, you know either your battery is bad, or your stats is off.

A properly designed battery charger (like the one in the phone) will not overcharge the battery. These chargers have circuitry to prevent overheat, and as the phone gets close to maximum charge, they slow down and then stop the current flow. They don't want exploding batteries!
EDIT: I do worry, however, that the phone is designed for the stock battery at 1.8v, and might overcharge a replacement battery (mine are all 3.7v). I have read of some people that had overheated aftermarket batteries when charged in the phone. I use my external charger for the spare batteries.

You don't need CWM recovery. You don't really have to be rooted, either. If you know how to temp-root, you can wipe the battery stats using adb shell or terminal emulator.
The file is located at /data/system/batterystats.bin. You can remove it by:
Code:
adb shell
rm /data/system/batterystats.bin
Don't forget to 'su' if you're using terminal emulator.
In my experience, the best time to wipe the file is right before starting to charge the phone all the way to full.
So, has anyone tried this lately with success? I'm a complete noob and have no idea about rooting, but might look into it if this really works for the Li batteries.

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.

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.

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.
