I have a battery / charging problem on my Gnex. The problem is that the battery won’t charge more then 60 %, drains quick and then the phone shuts down at 0 % ( in about 2-3hrs of use) and wont restart until recharged.
At first, I tought it was the battery so I bought one OEM on ebay. It did the same thing so I returned it and went to Telus store to buy an OEM.
Same thing happened with the new OEM. I then bought an external wall battery charger and charged the 2 batteries I have. When I put the first one back in the phone it said 12%?
I tried the second one which is the new OEM and same thing, its showing 12%.
I did a little test, I had 4.2.2 so I unlocked the phone and rooted (no more warranty anyway) I flashed back the ROM to ICS. No change.
So what I did next is I used the phone until it shut down at 0% and restarted it on the bootloader screen and left it on, on the bootlooader screen.
Well the phone screen stayed on for more then 3 hours, so I know the battery is good because there is no way that a 0% battery could power the screen for 3 hours.
So after it shut down from the bootloader screen, I charged it again, in the phone, and it went right back to 60%, I did try to wipe batt stats from recovery mode and battery calibration apps but no luck.
Is there a way to disable the auto shut down on the phone? The battery meter if definitely showing wrong charge stats. Is the battery controller part of the USB board or the motherboard?
The only thing I did not try yet is a custom ROM and Kernel.
Any ideas?
Sounds like a hardware failure... It's obviously not the batteries

I found where the Power Management with Switch Mode Charger chip is, on the motherboard! I wonder if there is some ways to access and modify the values of this.

For what it's worth, the same thing is happening to me. Charges to 64%, and it acts like it's only got a 64% charge - runs out fast. And I also tried a replacement OEM battery with no difference. I'm not completely convinced this is a hardware problem - though I guess it could be. I'm still stock Gnex (with the 4.3 upgrade - and come to think of it, this started some time after that upgrade). I was hoping it was some kind of kernel problem that i could fix by switching to CM. Anybody have any luck with that?
The same thing is happening to my phone, although I'm lucky enough to have it charge to 73%. Only realized the problem when I bought a new OEM battery and it stopped charging at the same 73%. I have a friend who has the exact same phone and will give her both my batteries to charge and see the results (with her phone then once batteries are reinstalled in my phone).
Outside of replacing the motherboard, would anyone know if there could possibly be a software fix? Has this happened to any other phone? If so does anyone know the results?
Thanks,
Stefan
My gt s6312 has charging issue. It never charge over 67-69% in my phone. I checked the battery in other phone its ok.....please help.....

Sounds like a hardware failure in the phones' charging circuit. Since:
- no software change (ROM or Kernel) fixes it
- no battery change fixes it
Then it's obviously the charging circuit in the phone. Time to get a new phone!
Well I've confirmed for myself that it is my phone charging circuit that's giving me bad info on my battery charge. I installed both my batteries in a friends Gnex and both gave me 100% charge reading on my friends phone. I then re-installed both batteries in my phone and both came back with identical 13% charge reading. So to me this is obviously not a battery issue.
Since my previous post in July my phone has gotten progressively worst. So I have now come to the point where I either have to replace the phone's charging circuit or replace the phone all together. I would much rather do the first as any replacement phone via my carrier would require me to pay more monthly on my contract.
So would anyone know with certainty where the charging circuit is located in the Gnex? Is it on the main logic board or the USB charging board?
Thanks

I am coming up to 6 days with this device.
I am running into a problem, the Telus tech support advised to return and swap.
I will have the device charged at 8am, at about 7 hours the battery will show close to 100% or 100%. The battery indicator will continue to show 100%, then the device dies, 0 battery.
Do I have a unit that should be replaced if the battery indicator does not provide proper information?
What could cause the battery indicator not to work?

People have talked about the "battery always at 100%" bug since launch. I haven't really heard of many reports of this with the Telus variant, but you should replace it as soon as you can, in case another one has and you need to use those 14-30 days for returning.
you just need to reboot the phone
i found how the BUG gets triggered
it's only when you charge it up to 100% with AC plug
if you charge it up to 100% with USB it doesn't get stuck on 100%
I had this problem aswell and it was only when charging on ac power. I also was using a 6ft usb cable i bought at walmart, i switched to the one that came with the phone and now ac charging is fine. I'd say if your using the cable that came with it and your still having this problem it could be your phone but i doubt it. Also as AllGamer said just reboot the phone after you unplug it and it is fine.
have this phone since satursday afternoon and im very pleased with it. im coming from a Telus P4000 after 4 years and half LOL. i needed an update i think, haha.
so far, i charged 3 ways.
in-car charged from a nexus one = 100%. lower fine
usb charged = 100%. lower fine
A/C from a nexus one = 100%. lower fine.
so if you're going to charge to with cheap ass stuff, that might be the problem, but so far it's all good on my side.
it's a defective unit.
I charge mine all the time with AC plug and it's never done that to me.
I just purchased a used Galaxy S3 and have had it for a couple of days already. This is what my normal charging routine is with any phone I have owned:
I shut the phone off before I go to sleep at night (usually around 11:00 pm) and plug it in. I'll get up at 6:00 am, unplug it and turn it back on. I've noticed though that with my new phone for the past 2 mornings, the red LED light is still on when I unplug it and when I turn the phone on, I immediately check the battery status and it has only charged as high as 92%. I am using the original wall plug (5V-1A) but the usb cable is not original. I also tried using 2 different ones with the same results. I'm just wondering what the problem could be and if anyone else has had this issue and what they have done to correct it? Thanks...
Try to reset the battery in CMW
Sorry, I should have also mentioned that the phone is bone stock for now...
Soooo, last night I tried a third micro usb cable and I drained the battery all the way down to the point where the phone shut itself off. I then plugged it in for the night and the charging light was finally green this morning. However when I turned the phone on, the percentage still only showed that it was at 92%. I'm not sure what else to try and who knows, could the battery be borked?
How long does the battery last? Just because the battery meter says 92% doesn't mean its not full, it could just be calibrated incorrectly. Put another way, as far as the OS know 92% is as far as the battery charges even thought the battery is at maximum capacity. Unfortunately im not sure if there is way to reset the battery meter without root access.
Yesterday the battery lasted a little over 16 hrs. That's with mobile data shut off, gps off, bluetooth off and pretty much everything else. I sent a hand full of texts, around 3 hours of wifi usage and about an hour of music. I can't really think of anything else I used it for...
If you are getting 16 hours on a stock battery there isn't anything wrong with it :good:. If the calibration of the battery meter bugs you enough you can always root it and reset the battery stats, either from CWM recovery or with a capable app. I have SD Maid which can do this with root access, but im not sure if the feature is available in the free version. Im sure there are other apps on the market that can do this as well, possibly free ones, but im almost certain they will require root to do so. If you do, charger the battery overnight to ensure a full charge, if possible use a usb power source instead of the wall adapter. This is a slower charge and actually can achieve a fuller battery charge. As soon as you remove the phone from the charger reset the stats and let it run down to nearly dead, i would probably do this twice to give the battery meter a good high/low limit.
Thanks! I will try this once I've exhausted all other possibilities that may be causing this. It does bother me a bit I'm not sure why. Maybe my OCD kicking in lol! I've just pulled the back cover off and the battery in it is 3.8V and 7.98Wh. The model number of it I believe is GB/T18287-2000 and below that it also shows 4.35V. Can anyone confirm if this is even the correct battery in it for this phone? Thanks...
That is the correct voltage and wattage....so yes it is the correct battery.
Thank you...
So another morning went by with the same issue and i figured i had to try something else. I went into The Source after work and went ahead and purchased the extra battery kit they sell (comes with the battery and a battery charger/stand) making sure that i could return it if it turned out that it didnt solve my problem. So i took my old battery out of the phone and when i turned it over i noticed a dent and a crease running down one side of it (probably the culprit). I put the new battery in, plugged the phone in and a little while later i got a green light and a 100% battery status! I was worried that there was something actually wrong with the phone but a $50 gamble later and im good to go. Oh i also tried charging the old battery in the charger but it would not finish the charging cycle (wouldnt go green after 3 hrs in it and the battery according to my phone was at 80% when i took it out).

Yikes! Lucky you noticed this before it turned into a big problem. With visible physical damage to that extent i would say the chances of that battery causing some serious damage is high, especially if it had went unnoticed and was used for extended periods of time. I would contact Samsung as they should replace the battery under warranty if the battery was in that condition coming out of the box.
See thats the thing. I bought the phone used and the issue was there since day one of owning it. Since these phones havent been out for a year yet, there should still be some kind of warranty on it and i guess it wouldnt hurt to try contacting samsung about it. Who knows, i could get a spare battery out of the whole thing.
Sent from my SGH-I747M using xda app-developers app
My only problem with that is who knows how it got that way, if it didnt ship from the factory in that condition Samsung shouldn't be held responsible.
True but how in the world could someone do that on purpose? The condition of the phone itself is about a 9/10. Unless they took it out for who knows what reason and dropped it and whatever else. I'll never know. Maybe i will just leave it alone. Everything is back to the way it should be...

Hi,
Few days ago I noticed that my S3 was charging extremely slowly. I had it plugged in for 10 hours and it charged maybe 20%. I needed a full battery so I swapped the one from my battery charger (the official Samsung charger and battery), which was supposed to be at 100% according to the charger. Phone started up, battery was at 100%, and a few hours later it died.
Now, if I plug the phone in to charge it will gain a percent every 10 mins or so and it will only charge to about 54%. Doesn't matter how long I let it charge for, 54%. There was one instance where it charged to 100% but 2 mins after I unplugged the phone, it was back at 54%. The battery charger keeps charging the two batteries to what it says is full (green light on the charger), but when I put it in the phone it appears to only be between 10% and 50%.
Today, I took a battery which the charger said was at 100% and put it in my phone. Started the phone up, it said 2%. Put the same battery in my friends S3 and his phone said 98%. Back into my phone, 18%.
Things I've tried:
Leaving the phone plugged in for an extended period of time
Taking the battery out for 10 mins then putting it back in
Different chargers (some official Samsung, one BlackBerry, one no name)
Charging from USB and AC
Like I said, tried putting the phone in a different S3 and no problem with that. Only has a problem with my phone
Booted into recovery (TWRP) and it will report the same percentage as the OS
Tried to download a few different apps to check the current that was charging the phone but none of them worked for the i747m.
Also used Better Battery Stats to see if anything was draining the battery or had a partial wakelock. Nothing out of the ordinary.
When the problem first started I hadn't updated the software (CM 10.3) but was still planning on doing a restore later tonight.
I've searched xda and google but haven't come across anything that has worked. If anyone has any suggestions it would be greatly appreciated.
Thanks!
Restored back to stock last night using Kies "Firmware Upgrade and Initialisation", but that didn't help. I'm going to assume that is hardware at this point. Unfortunately, I'm out of my warranty. Right before it ended I took the phone in for repairs and they replaced the micro usb port. Could this be causing the issue? I had originally thought this but like I said, if I take the battery out and put it in another phone it sees it as being at 100%.

You said the phone itself will only charge the battery to what your phone reports as 54%, correct? What i didn't see was at that stage did you try it in the other phone? Just trying to determine if the phone is actually charging to 100% or not. If it will only charge a battery half way it is entirely possible the usb port repair wasn't up to par but I find it hard to believe that it would cause such dramatic drain as well. If it does in fact charge the battery fully then your problem is more than likely with the sensor responsible for report battery condition. Whether the sensor is bad or is simply in need of recalibration is the question at that point. Regardless of the actual charge of the battery if the OS is being reported to that it is below tolerance threshold it will assume the battery is dead.

Yes the phone only reports a 54% charge at most. I took a battery from my battery charger which was at 100%, put it in my phone which reported 2%, then immediately into another S3 which reported 98% and stayed that way for 5 or so minutes.
Given enough time (upwards of 10 hrs) charging the battery via the phone and the phone will report 100%. But then within a couple minutes the phone will report 54% and will discharge as normal.

It sounds to me like the sensor responsible for reporting the battery condition to the OS is screwy. It could either be bad and need to be replaced, which would most likely mean a motherboard, or just needs to be calibrated. You can try resetting the battery statistics from CWM recovery if i recall, i wasn't able to find the same option in TWRP if that is what you are using. Its an outside chance but certainly worth installing CWM to give it a try over replacing the MB. Lastly, if you haven't already tried you can try flashing back to stock and see if that corrects the problem. If it is software related this should work, if not you cant pretty sure its hardware.
EDIT: I loaded up the latest CWM and the option for resetting battery stats isn't there so either they removed it or i am just remembering this from some other device or ROM i used in the distant past. In any case i found THIS thread that should assist in attempting to recalibrate the battery reporting.

Ya I tried flashing stock previously and that didn't help. I had considered resetting the battery stats but I read a lot of forum posts that said this didn't have any affect on the battery and was automatically done whenever the battery was fully charged (or completely empty can't remember which one).
I ended up taking it in to the provider but they said I would have to send it out to Samsung and pay the cost since it was out of warranty. They suggested that it would be likely that I would just end up with a new refurb for $150. Instead I took it into a shop nearby and they repaired the motherboard for $90. Got it back earlier today and so far it's working fine.
I been having troubles charging my S4 and I used the one that comes with the phone when you buy it and it charges completely but now I have a different one that's made by Samsung but my phone wont charge completely. I put it on the charger at 10 am and by the time I go to school its at 60 or 70 percent everyday,even when it's on airplane mode. Is there a way I can fix that? I tried wiping my battery stats and I also got Battery Doctor but that doesn't help either... So can someone help me with this issue?
Additional information:
Running Wicked Rom.
Stock Battery
Not even 2 week old yet.
I haven't dropped it at all.
No water damage at all.
Also charger is a 1.0 amp charger made by Samsung.
I'd consider flashing to stock and starting over, buying another battery, or another charging cable.

I still use the stock charger and cable that came with the phone and my phone charges at approximately 1% per minute (or even a little higher) when it is on the charger. If yours doesn't charge that fast try another cable (borrow one if you have to or go to the T-Mobile store and ask them to use one of their cables to test it for you). Good news is that even if your battery has gone bad you have a phone for which the battery is easily replaceable.

I have figured it out. I uninstalled a few programs that wouldn't let my battery charge completely. I noticed there were three applications running while my phone was on and those thee programs were running all the time without me knowing. So I Delete Battery Doctor, Clean Master, and Wakelock Detractor. After I uninstalled those, my phone was charging a lot fast and when I woke up today, my phone was at 100% and I was happy. I thought I would have to re-flash my rom.
One fine morning my Note 10.1 2014 battery started showing as 0% and will not 'charge' (i.e., percentage will not rise). As a result, the tablet has to stay plugged-in always to use it (just like a desktop computer). The moment it is unplugged, it shuts down in 1 or 2 seconds. Tried different chargers/cables/flex cables/new battery/uninstalling/reinstalling/warming...& what not. But nothing solves the issue. I came to know that the battery is actually holding/taking in charge which is evident from the fact that the tablet runs without being plugged-in in the recovery/TWRP mode! It seems just that the android OS is not recognizing the charging. Any help would be appreciated. Thank you!
Is the battery really good? The boot menu uses a lot less current than normal boot up operation.
Otherwise you're looking at a possible mobo failure. If it has a charger pcb it could be that.
A Samsung Experience center at a Best Buy might be able to sort it out for you.

It is not the battery, I am pretty sure! As for the other possible causes suggested, it seems Samsung considers the product too 'old' now to look into/offer any service/parts replacement. Anyway, thanks for the quick reply!
I got the same experience. Recently installed LOS14.1 on my Samsung 2 7.0 and battery just drained and inspite charging it overnight never recovered. I think it's really the LOS 14.1. Now I cant even boot it up anymore.

Please do post, if you find a solution!
I strongly doubt that LOS14.1 (lineage-14.1-20210320-UNOFFICIAL-lt03lte) is the culprit as my old P605 still works with the unchanged battery.
Once charged it lasts for quite some days (usage 0.5h/day) without problems.
It's always in flight mode and mostly WLAN is shut off.
It's not that cuz of an OS it's the old battery problem....
Same thing happens to one of my cellhphones.
I charrge it to 100 % while it's turned OFF then tomorrow I turned it on and battery is at 1 %, 0 % and shuts off.
It's just old Li-Ion battery which needs replacement.
After having replaced the battery with a new one with about 50% charge the discharged P605 would only recharge to the level of the original charge. It returned to normal behaviour after charging once with the original 5v/2A charger and the original cable with the second GND contact missing. If the latter did the trick, with most cables u can't tell whether the contact is wired to GND or not.
But in the days of miniUSB, the second GND was sometimes used to put the device in charge or pc connection mode, by swapping cables.
