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
did you try removig battery stats from recovery mode?

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.

Slight oddity with my Vibrant.
Occasionally when I charge the phone, it will show that it is completely charged--battery gauge will show full, About Phone will show 100% charge, all of that good stuff. When I unplug the phone, my battery gauge will instantly drop to 97%.
Additionally, for the entire duration of this particular charge, my battery life will be total crap. And by total crap I mean draining 1% in five minutes with the screen off, going from 97% to 78% in two hours with the only use being a quick check of bus schedules.
However, if I notice this 100-to-97 instant drop and plug the phone back in until it charges to 100% again, it will not display any of this odd behavior and battery life is awesome as usual, with standby power consumption at 1-2% an hour.
So... what gives?

Dont worry about when you unplug it, its just a inaccurate reading.
It happened to me this morning with Axura, and my battery showed 97%, but the 3% was given back without me knowing, does your phone stay at the 97 for a longer time? it should, and also some people say do a battery calibration.
its like
charge till' 100
drain it to 0
charge till 100
and then on clockwork recovery go to advanced and do wipe battery stats or something
^ im not sure someone correct me if i'm wrong about the calibration.
I conditioned this battery after flashing the ROM last month. You have the directions mixed up... should charge to full, boot in clockworkmod, delete battery stats, reboot, drain to 0, charge back to full.
And no, it doesn't stay on 97 for longer than it should; as I stated in the OP, if it does the 100-97 drop, the battery life is significantly worse than when it acts normally.
I get the same thing. Actually at the moment I am trying to unplug... see the 97% and plug it back in, it will then say fully charged, I unplug it and it says 98%. I am going to repeat this until it actually says fully charged when I unplug it and then reboot to recovery and wipe the stats.
What I am confused about when it comes to reconditioning and wiping is even when the phone says "fully charged" when I reboot to recovery and wipe, once the phone has rebooted it says it's charging again. Should I leave it in until it says fully charged or unplug it after it boots?
It seems to do the 100-97 thing primarily when charging via USB. Almost every time I've seen this happen was when it was charging off my laptop.
I've noticed also that when it does this, the battery icon (I use Segmented Battery Mod) shows "100" solid without a flashing plug icon. If I unplug it, it will drop to 97. If I plug it back in and it actually charges completely, it will flash between the plug icon and "FULL."
hmm...mine does it no matter how I charge it.

Mine USED to do thar with Nero beta 3 now on Axura IRS dine I've been using it for 20 minutes and still at 100%
Sent from my SGH-T959 using XDA App
Updated to Nero v3 and now I have the problem constantly. It will always claim 100% charge when it isn't actually fully charged.
Sent from my SGH-T959 using XDA App
If you've flashed the ROM, do the "recondition" -- or if you have a stand-alone (external) charger, just charge it full, then put in the new battery and wipe your stats. (The recondition thing -- charging, draining, then charging -- is just a theory that on the second full charge you'll get "more" charge in there after a full drain -- I doubt this is true, especially if your battery stats are hosed to begin with.)
As for the dip after you unplug it -- this is just the battery manager varying the maximum charge level to optimize battery life. Laptops do this all the time -- even when they're plugged in, they'll let the machine run on battery power here and there. For a new battery it might only let it dip to 97%. On one of my laptops it has decided dipping way down to 86% is optimal. Just depends on the battery health, usage patterns, etc.
Battery life was pretty bad when I first flashed Nero, but now that I've wiped battery stats, the battery life seems much better. It still does the 100-97/98 thing, so I'm guessing it means my battery is still pretty good despite all the heavy use!
The JL5 modem seems to have worse battery life than JK6 (only very slightly though) but it doesn't get stuck on EDGE like JK6 did... net gain in my opinion.
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.
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.

If I keep my phone on charging even after its on 100%, it starts rolling back. As in from 100 to 99 then 98, even if its pluggen in.
Don't know what kind of a problem this is, hardware or software.
Or there's some issue with the battery.

But usually I put it on charging at night before sleeping.
And when I wake up in the morning, the battery % becomes even less than what it was when i plugged it in.

Maybe You have some program that syncs something all the time. Did You try to turn off data and wifi. You can always check it if the reason is the hardware or Software. Just make a backup of Your whole ROM, delete the data and leave the phone over night. I hope it is only software problem.
EDIT: Does Your battery go hot while charging? Oh, and try to wipe battery stats

The x10 charges the battery to full then if still plugged in it will stop charging until batt drains to set level ,then will charge to full again and over and over all night. X10 wont over charge batt when left plugged in. Kernel/bootloader handle this. There is an app current widget that can log charge levels.

EDIT: the best tip I usr for battery life is, let batt runout until phone shuts off, then pull batt, then plug in charger, then replace batt into phone, then phone will boot, enter xrecovery on first boot and wipe batt stats. After wipe while still in xrec pull batt then unplug. Now plug in phone then insert batt. Phone should boot in charge mode( big batt icon only on screen) dont start phone untill light green for 1-2 hours to get full charge . I do this about once a month, when phone starts to shut off around 15%

As mentioned above as well, this is normal. After charging to 100%, the phone stops battery charging, and will activate charging again only when battery falls a bit (say 97%). Also, battery heating while on charging (and also when using the phone continuously while playing a game) is normal. Relax.. your phone is fine
@ToledoJab
I am having the same issue with battery... phone switching off at 15%, even at 22-23%, when playing a game or something. But switching it back on, and leaving it idle, phone might run for another 2 hours. So it is the extra load while running a game that the phone cant take any longer (i remember getting the 15%,10% and 5% reminders earlier while playing games)...? Does the battery calibrate method actually help in your case? does it go all the way down to 0% or 1% before shutting down.. ?
I just did this after posting that. And yes my phone reported warnings @ 25% 15 10 5 and then shutdown @ 1%.
This way is like reconditioning an old rechargeable ni-cad batt.
All this does is completey drain batt then, with least amount of drainage (phone on, apps& radios running) allows battery to full charge.
There is also a way called recalibrate battery. But this way over charges the batt.
EDIT: I think the phone load will effect reported batt left. I think batt gage use average loads to estimate remaining power. Meaning games, full brightness of LCD, radios -3g -GPS -WiFi -Bluetooth will use more than avg power
edit 2: I found this thread also has some very good points and links. after reading this i will not intentionally take my batt to 0%. I hit 0% about 1-2 times a month on accident as it is. i will just make sure when i do go 0% to wipe stats (dont know if it helps or not) then preform a long (overnight) full charge with phone off.

I have searched the forums but not found a thread which is similar to my problem.. I know there are battery drain issues with wifi etc but this is wierd and only started happening a few days back.
Basically i plug phone in to charge and it charges completely normally and quickly as it used to but only charges up to about 68/70% then it basically stops charging any higher, LED still red, charging display over battery still there. Turning phone off, rebooting, unplugging and plugging charger back in all makes no difference!
Any ideas what could be the cause of this? how to resolve?
I'm on stock JB, using the official wall charger and USB cable and i made sure the battery was full when i updated to JB as well.
Try a different battery, these are getting to the point where some will start to fail, six month warranties on batteries for a reason.
Well i have a £1.99 spare battery in atm as i run the original battery completely flat today. Seriously though be surprised if battery fail after 3/4 mths - never had battery dying issues on previous phones i've had until they were a good 2/3 years old.. Always a first though LOL
Its like the battery is saying its fully charged at 70%, now its completely flat i will charge it overnight with the phone off to full (if it gets there) and see if is resets the battery callibration or something.
Try to wipe battery stats via cwm recovery/advanced.

It has nothing to do with wiping battery stats. I think Kangburra is right...
UPDATE.
Shamed to say that i am not rooted yet... I have been there and done all that on my old phone ZTE Blade, but i really like the added functions that TW brings and don't suffer much in the way of anoying redraws or lag etc (although i do feel that TW could be optomised alot better along with better RAM Management)
I was going to at least root to sim unlock but got a sim free unlocked phone so had no need, then other stuff i wanted to do like freeze samsung apps etc is all possible without root and i've not come across that "I" need root at the moment.. was going to for APPS2ROM but i got no need to free up space yet.
Cheers for the suggustions though - I have that battery callibration app already (from old phone days) obviously don't work though.
Anyway - I am monitoring battery atm but it seems that running the battery completely flat until it turned itself off and charging overnight with battery off has resolved this issue - maybe this reset the battery stats and recalibrated it.
Its back to normal now, charges upto 100% as normal!! Fingers crossed this was just a blip
