Battery not charging past 82%! Help!

Hi,
I bought my GSM galaxy nexus about 2 months back. I unlocked bootloader, rooted and installed stock JB, with franco.kernel. It worked fine for maybe a month. Then, charging the battery started maxing out at lower than 100%. Now, it does not ever charge beyond 82-83%. (in battery settings, it shows "82% - Not Charging" even with the stock chrger plugged in. I also charged using USb, the iPhone adapter, and another samsung charger.
I put this 82% charged battery in my friends GNex, and it showed 96% on his phone. It even charged to 100% without any hassles.
I put his phone's battery in my nexus. On his phone, it read 60%, on mine it showed 25%.
so, my phone's battery reading is off by almost 20-30%.
i wiped the phone FULLY, installed CM10, installed stock ROM, stock kernel, but nothing seemed to change this behaviour.
Any ideas which might help me, or do i send it to google? (which will be a lot of trouble since i dont live in the US).
Thanks.

Charge it fully ( in your case to 82%). Then boot into cwm recovery and try to clear the battery stats.

Battery stats has absolutely nothing to do with it. Charging his phone at only 4pm while having it gave down on an espresso colored end table would yield the exact same result.
No info related to battery charge is contained in that file. It is only a list of apps that have run on battery. Nothing more. Furthermore, the os periodically purges the file on its own.

Just a curiosity, does your phone still lasts as long as 100%?

yes, i believe it does (It still gets me through the day, like before). I think it stops charging because the battery gives a feedback of being full, just dunno why the phone thinks its at that low percentage..
could juice defender have something to do with it?

Nope, Juice Defender only turns radios off and on. Nothing to do with how phone reads the battery %
May I ask what you have done to fix it?

I am unable to anything that can fix it. I have tried wiping battery stats (knowing it's useless), drained my battery and recharged, full wiped etc.
The reason i'm asking about juice defender is that i switched JD on some time back (on extreme mode). The battery was at 66% when i unplugged it and put JD on.
Since then, the battery reading has come UP to 70% (no charger connected, and it even shows discharging in the battery settings page).
I'm thinking i'll charge to whatever level it allows, then leave it for a day with juice defender on, maybe it'll go up to 100%.

Sorry that I cannot help you, but I've seen a lot of threads about this. I think you should search for them and see if there's an answer. I think that's the best choice until somebody comes up with something

silly question.. have you tried another battery? the problem could be the battery itself.

You have obviously a reading problem not a battery problem. Something got messed up somewhere. I recommend wipe clean your phone and bring it back to stock. If it works, start toying with it again, if not you are ready for warranty exchange

If you already flashed back the stock kernel and that doesn't fix it, I'd say your gnex has a hw issue.

Thanks for the replies.
1. As i said, i put my battery in another Gnex, reading was much higher, and charged to 100%. I put my friends battery (at 60% on his GNex) in my phone, it showed 25%. Not a battery issue, i believe..
2. I wiped FULLY (including system, data, cache, dalvik, battery stats. everything except my storage) and went back to a rooted stock JB rom and kernel. no change. so i switched back to CM10.
So.. i guess hardware issues?
Also, could you help me out by giving a link with this problem elsewhere, i cant seem to find one.. i'll keep searching though. Thanks..

I know this is over a month old but I was wondering if anything has changed on the status of your Nexus. I have been having similar problems, only charges to a max of 63% though then dies in under 5 hours. I have tried a couple things you listed like going back to stock ROM, trying other batteries, pulled SIM card and battery out and just left it on a desk for 5 hours.
Did you end up having to send it back to Samsung?

I had already faced same problem in my samsung grand prime device

I had the same problem with my Meizu (!?) phone. The solution was to turn the phone off and charge it. It would pretty quickly go over that fixed % and to 100% full.

Battery Issues

I started running into some battery issues earlier today. I was on AOKP without any issues and one day the battery just started draining very fast. I went from about 50% to 15% in a matter of an hour. That night I slept with my phone charging and it did to get charged passd 54%. And it's charging very slow too. I thought it might be the ROM so I flashed Slim Bean. But it is not heling at all.
Anyone have anything similar going on?
What can I do?

Try calibrating the battery and go like 2-3 charge to discharge and see what its like afterwards

Will do. I'll post back

Yea it takes a few rundowns to get into the sweet spot, I thought I was getting horrible battery life till someone suggested that to me now I get about 32-33 hrs on a charge. Which I think is about prefect, I don't game on it I just use everything else all the time. I have ps3, xbox360 & psp for gaming
Sent from my SGH-I747M using xda premium

Well it's been charging for about 6 hours now and it won't get past 54%

I let it charge all night and when I woke up it was finally at 100%. I left for class and unplugged my phone at 7:40. 20 minutes later it was down to 47%. Then another 2 hours later, it was at 11%. Obviously it is draining far too fast. Will AT&T replace my battery? Or does it look like I'm gonna have to buy a new one?

What I normally do is charge it to 100% then boot into recovery and wipe battery stats. Reboot and don't unplug the phone until it again says that the battery is full. Then run with it and see if it helps.

Go ask them I don't see why they wouldn't replace the battery, it does sound like its shot that kind of drain isn't normal at all
Sent from my SGH-I747M using xda premium

I had the same issues with not getting to 100%. Seems like leaving it on the charger for another couple hours (overnight) got it there.

So I went to the AT&T service shop yesterday and she took my battery and put it in a different Galaxy S III and it showed the battery was charged 97%. In my phone, it showed 23%. She told me that it had somthing to do with my phone being rooted. She said the software on my phone was being "tricked" into believing that the battery is a lot less full than it actually is. She told me to unroot my phone and flash it back to stock. So I did that yesterday and it is still no better. I don't know what to try.

Wiping battery stats doesn't help battery life... Something i learned a long time ago with my X10

My Android system is almost always under 15%. Seeing it that high is alarming. I assume you've tried full wiping and changing ROMs?

Yep. I must've flashed my phone to stock at least 10 times now. Ive tried rooting and Unrooting, clearing my flash counter, I really don't know what else to do.

Thought I'd try installing CM10 just to see if there would be any difference. Screen Brightness shows up as my highest percentage on the battery usage and Android System is much lower on the list, but the battery is still not charging or discharging correctly.

I would unroot and take everything back to stock, then go back to the AT&T store you went to before and show another service rep that the phone is messed up and see if they give you another one.
Good luck

mrb1946,
Even though your S3 is reporting percentage values as you stated....the PHYSICAL battery did not drain from a real 100% to a real 47% in 20 minutes. It can't actually physically drain that fast. It would be on FIRE! So, either the calibration of the rom/software or the battery itself somehow messed up.
Also, during that time...was the battery/S3 HOT? That physical evidence would account for some of the drain if it's coming from a rogue app or misbehaving rom component. Did you post a battery drain graph? And were you monitoring the cpu activity during these high drain periods? I mean...periodic checks to see if your CPU is stuck on HIGH freq and if you have any wakelocks shown under the battery graph.

If this problem is still occurring, here's a thread explaining a possible drain from android system. http://forum.xda-developers.com/showthread.php?t=1827087&highlight=android+system

how long does it take you to charge your battery?

mine usually takes 3 hours.
the thing is if i touch it and turn the screen on and use it for awhile, i notice that my battery % isnt going up. it just stays to the % where i start using it, even for 30 mins.

I read your thread earlier and let my phone shut down by itself then charge it while it is turned on and most of the time DayDream is also on. It is about 1 hour and 50 minutes to be fully charged. I do not remember it ever exceeded 2 hours unless I am playing a heavy game while charging.
I am running my own AOSP ROM and trinity kernel alpha 7.
A similar thing happened with me when I had my S II. The percentage holds and does not increase, but if I reboot the phone then it shows that it was really charging. For example if it stopped on 45% for some time, then after reboot it may show something like 75% immediately. I think it was a ROM or kernel problem, so try another combination and see if your problem is fixed.
Hope this helps

If you do a full wipe (system, factory reset, cache, and dalvik) and install a fresh ROM, does the slow charging and inaccurate percentage exist as well?

Is it a problem with the charger? If it's a third-party charger, maybe it doesn't deliver enough juice. If it's the mfg's charger that came with the phone then maybe it's dying on you.

Doesn't anybody use math? The stock battery (1750mah) will charge in just under 2 hours on a 1A wall charger assuming you leave it alone to charge.

Battery Calibration[Root][No recovery][APP][02/05/13]

BATTERY CALIBRATION
Hi!
As we know when we install a new rom we sometimes have battery drain or when we flash a new kernel etc..... what is this?? this means that your battery goes to 0% very quickly!
The normal steep is goes to recovery and wipe battery stats!!
but what i do if in recovery don't appear something like wipe battery stats??
simple!! be sure that your nexus is completely charged,download this app ,, tap on battery calibration !! (after that charge your nexus without break)and congratulations.... buy a beer and make a party!!
I don't made this app.... just share it....
i will upload the link in a note pad... why?? simple.... i can't put links!!!

There is no need for battery calibration. Just discharge to 0% then charge back to 100% and you should be good to go.

It doesn't even need to be to zero.
Everyone should go to batteryuniversity.com and read the articles on cycling and charging li-Ion batteries. Then you will be able to make sense of conflicting advice on batteries.

mmmmm thanks for the page....

The myth of wiping battery stats was thoroughly debunked almost a year and a half ago. It is a 100% true statement that neither this app nor wiping battery stats in recovery has ever affected anyone's battery life or battery indication in any way, shape, or form.
Want to know why battery drains after flashing a new rom or kernel? Hint- it has absolutely nothing to do with incorrect battery stats- totally disregarding the fact for a moment that batterystats.bin has absolutely nothing to do with battery charge indication.. After flashing a new rom, your device is actually using more battery than usual as accounts are set up and synced. Likewise, after flashing a new kernel, it takes a short amount of time for the kernel to "settle."
If you still believe the myth that battery stats need to be wiped every now and again, there's an even easier way to do it than wiping in recovery or using some snake oil app... charge your device to full or near full and then unplug it from the charger. Voila- you've just successfully wiped battery stats!

OP, stop posting nonsense. Seriously.

Strange battery behavior
It's actually odd, my battery started getting stuck at 100% like a week ago or so, after 11 hrs standby time and 30 mins screen-on time, it doesn't even drop 1%. However, it shuts down normally at 1%. I actually tried so many things to fix this, i opened the back cover and pulled the battery out, i let it run dead and charge it all the way up, but it just seems to like that 100% mark. Since it actually shuts down at 1%, i wanted to make sure it's completely dead, so i booted into recovery and oddly, with max brightness in twrp, it took about 15 mins for the device to completely shut down.
Any ideas what might fix this?

Bear in mind that you optimally do not want to discharge the battery to the point of shutdown. Doing so shortens its lifespan, and can trigger the N7 to go into a hibernation mode on order to protect the battery from permanent unrecoverable damage due to a deep discharge.

The app has nothing to do with it as the only thing it clears is the list of processes that have operated on battery since the last full or near full charge.
The only "calibration" that an end user can perform entails a complete discharge/charge cycle. This resets the flags for the battery's internal fuel gauge.

This is all the recalibration the device needs.
Naja is 99% correct. It's not the only calibration you can do (you can wipe stats), but it's the only one you should need to do.
batteryuniversity.com has a couple of good articles on the care and feeding of Li-Ion batteries. There is a lot of less than accurate info that floats around about batteries. The above site is a good way to learn the difference.

As far as I am concerned I ended up replacing my batteries after +10 months of daily intensive use although the battery status was reported as good. I bought a Samsung original part from eBay and followed a Youtube tutorial. I'm glad to report I did not break anything and obtained significantly enhanced runtimes.

Supposedly holding the power button down until it shuts off is simulating a battery pull. Only other way I know of is to open the device and physically unplug the battery.
Have you tried just running the battery down to nothing, then with the unit off charging to 100%, then keeping it off the charger until dead and then charging to full agian? This may help re-condition the battery. I don't have any evidence to suggest this works but others have reported longer battery life afterwards. If it doesn't work then nothing lost.
Either that or just buy a new battery.
