I Have scoured the internet looking for answers to why my N7(2013) will not fully charge so I have came here hoping to find an answer to this madness.
First a little about my N7 : Android Ver 5.1
Kernal Ver: 3.4.0-g7597781
Build Number: LMY470
Not Rooted
Everything stock
I have had issues with charging this battery since I first got it. At first it would charge up to around 81% then 67% and it would just seem to bounce around a lot (between 81-50% charge) I have done 3 full restores and never once has it read 100% battery, I have tried draining the battery completely then charging it, I have tried some apps to monitor the battery nothing I have tried has helped get the battery to 100%.
Actually the battery hasn't charged up past 67% this morning with an overnight charge and that was a good 8 hrs on the stock charger.
I have read tons of material online to try and understand what may be causing the issue but so far haven't found anything remotely close to what is happening with my device.
If someone would help me with a potential fix or a solution that would be fantastic!

Hi, phone seems to be charging much faster than im used to. i mean like from 4% to 70% in under 2 hours.
Wondering if this is an issue with my setup (in sig) or some other factor...or if its not really an issue.
Cant comment on the battery life after a charge like this as i have not used it yet. I have however had poor battery life the last 2 days, but i think that was because of the pri/nv 1.90 issue, and have since downgraded to 1.7x.
tomorrow i hope to see the expected battery life, but the charge time is concerning me.
Anyway like an app to test the battery readout for accuracy? currently using mini info along with the notification area battery indicator.
Thanks
Was this with the stock charger? or? I know when I use the usb charger that came with my Nook with my EVO it charges in about 1/3 the time. I've never really compared how "solid" the charge was but I've always done this when traveling and don't remember my EVO draining abnormally fast.
Until you can conclude that your battery life has suffered then this sounds like a blessing. What I would suggest doing is letting the battery drain out completely before your next charge. Batteries need that sometimes.
I always use the stock Evo usb cable with either my powered USB hub or the stock wall charger. Its been my experience that the USB charging is a little slower then wall charging, but last night it charged extremely fast. I went from 4% to 100% in a little under 2 hours.
Could have just been paranoid because my battery life yesterday was abnormally low, a result of having pri/nv 1.90 i think (i downgraded to 1.7x last night).
I "calibrated" the battery last night by charging to 100%, unplug, replug, shutdown, unplug/replug etc. Did this a dozen or so times then cleared my battery stats.
Battery life will hopefully be normal today. Ill report back my findings.
Something I've discovered recently, and I am not sure I can explain it properly, but here goes...
I am running SRF 1.1.1, I don't believe this is the cause of the problem, but probably something that should be stated.
So running SRF1.1.1, I usually get wonderful battery life. I typically use an external charger and swap out batteries when they get to around 10-15%. This has worked well for me.. For the past few days I got lazy, and just plugged my phone in and left it on my desk to charge, no problem. When the battery is fully charged and I unplug it from the charger, I noticed it was rapidly draining.... I am aware that often when charging via the phone the battery immediately drops to 96% when removed from the charger. So this is normal, but I've noticed that after unplugging from the charger I lose about 10% per hour, when normally it may be 1-2% depending on usage.
To remedy this problem, rebooting seems to fix this issue. I have also had success with the airplane mode toogle. I don't see any odd usages showing up in spare parts, but is there any other way I can test this theory?
Thanks!!
Edit: Wanted to add, that this only seems to happen when using the charger cable with the phone. Swapping batteries does not seem to produce this issue. It is only when the phone is removed from the charger.
I haven't calibrated by battery lately and thats exactly what mine does too, I would stick to the external charger because our phones charge excruciatingly slow unless off. Try calibrating by charging to full while on then turn it off and let it charge more and repeat that a couple times then boot into cwm go to advanced and clear batt stats
Is there an advantage to calibrating a battery if it is not being charged in the phone?
This is the TWS bug mixed with no battery calibration.

similar to what i have been experiencing. i enjoyed great battery life with srf 1.1.0. have a 3500mAh battery that i used to get about 48 hours out of, but now it is averaging around 25-30. i do not have anything but the stock battery to swap with, so i do put it on the charger nightly now. i was planning to recalibrate the battery tonight to see if that cleared things up.
what would be a way to fix the tws bug?
I have noticed this too. It seems to srf seems to not like my extended battery. I am lucky I get a day out of it. I some times will plug it into one of my work computers just to bring the charge up a little and it starts flashing red and discharging this is only on my extended battery not the 2 stock ones I have. I have even tried different kernals to see if that was issue it isn't.
Sent from my lean mean drunken machine useing XDA Premium and a 12 pack of Sam Lager
in looking at battery usage in >settings>about phone>battery use>cell standby i see usually 0-5% tws.
one thing i have noticed, though have not tested is that the screen appears brighter, even at the minimum setting than what i remember from srf 1.1.0
Hi All,
I am having troubled battery stat since I last flashed to a custom rom.
The battery will NOT reach the CHARGED status, and hence the battery stat did not reset and go on for days.
This morning I have decided to do a full wipe, but it appear that the same problem persist, at 68% on AC (most of the time stop at a random value) , it says NOT Charging.
I also thought that it could be the battery that was giving the problem, so i tried with a spare battery that i have, same results. Even when i Swap battery the stats stays.

Many people (myself included) have been having similar issues as of late. I too have separate batteries, neither of which is older than 6 months, and both exhibit similar behavior. I'm sure you've looked through and perhaps saw these threads, but I am trying to shed more light on the issue as it is perplexing many.

my troubles started soon after i flashed my first 4.2 rom. it started with only charging to 90%, now my one battery gets to 68% while my other only gets to 65% (30% loss in the past month). I am hoping an explanation comes up soon.
I had the same problem too, but for me the solution was switching between a few roms and calibrating my battery (wiping the battery stats). What ROM are you using?
I am on paranoid android, it was working fine until i did beta 8... and never able to do again..
what rom did you switch around to get it fixed?
Does anyone know any certain solution for this problem ?
After 4.2 upgrade , my battery gets to about 80 % and everyday It decreases
It bothering me and since in my country Google has not any agency for warranty replacement or repair,I'm gonna sell my Gnex if It problem goes on !
It's really strange. I have the same problem also, using either the official Apple 5v @ 1amps charger or a samsung charger with the same specs my phone only goes to 98% 99%, but when I use a generic charger ( I only used a 1-2 times with GNex) that's rated 5.2 volts (scares me) at 800mah it reaches 100%, as it does with the PC also.
Hey all,
I have done some searching around here and on the web but have not found anything (with a solution at least) similar to my problem. First off, here are the details on my phone:
SGH-I747M Galaxy S3 unlocked on Telus
Rooted on stock ROM
Running JB 4.3
Currently have CWM 5.5.3.7 installed
Now the problem:
My phone does not seem to enjoy extended batteries. I have attempted a few replacement batteries from battdepot.ca (their replacement is a 3.7V 2300mAh) and two of the Hyperion 2200mAh 3.7V replacements all with the same issue. I have sent the batteries back and had them tested and even had new ones sent to me and still the same thing happens so I am certain it is my phone. I have had this issue since before I rooted the phone and was on JB 4.1.2.
I charge the battery overnight every night and it usually says 100% in the morning. When I unplug the phone the battery percentage immediately drops down to 88%. When I get to work about 45mins later and look at the phone, the battery is usually around 94% (it always creeps up slowly to a max of 94% after unplugging it). If I plug the phone in at work it will go up and down between 96ish% and 84% but will not go back up to 100% unless I leave it charging for the whole work day... mostly it will then just hang around the 85% mark. Most times I still get pretty decent usage but other times the battery percentage will drop from 94% down to 15% and below.
I have tried "calibrating" the batteries to no avail. Has anyone else had this issue? Is there a way to fix it? I only have this issue with batteries above the stock 2100mAh.
Any help is much appreciated!
Hey
Had the device since around August '14 and never had any issues. Recently though I've had some seriously bad issues with charging. I was running Paranoid Android and my device died, once it finally reboot and started charging it took 5 hours to get from 4% to 70% - With completely no usage. I then got home and flashed the latest Resurrection Remix (Just in case the ROM was the issue) and unfortunately my problem has worsened.
Device takes literally 12 hours+ to charge from under 10% to 99% (I haven't seen it yet 100% in 2 days). When it finally does charge it drains quickly from the lightest of usage (WHILST still charging). I've tried 3 different main plugs and sockets, numerous USBs (From the official LG one to Samsung, Huawei, Polaroid, unbranded etc etc) and my problem still remains.
I can't just flash back to stock as it's currently dead and refusing to charge (Takes a lot of messing around just to get it to turn on and charge from 1%).
Any help would be very much appreciated as I've never had this problem on any of my devices, when I checked my battery health last week it was still reading as 'Healthy' so I really don't think the issue lies in the battery or chargers.
Thank you,
Curtis.
When you said you flashed back to stock, have you used the TOT method?
Noted that you mentioned that your battery should be fine, but probably worth to check it with another battery.
