Without fail my Nexus 7 seems to die around 25% battery. Strangely, this only happened after I unlocked/rooted it, but now it happens every time. I even charged to full, used CWM to wipe battery stats and let it run down from there, still no dice.
Safe to say I should get a replacement?
No? I'd be surprised if I'm the only one having this problem... Seems like the Nexus 7's hardware issues are pretty widespread.
I must admit, when it died, I dont know what % the battery was at.

Since youve rooted it, your warranty may be void, assuming that it wont be have you tried a custom rom? as daft as it sounds i had this issue on my old HTC desire, but a custom rom did fix this.
I havent had any issues at all with my nexus 7, my nexus was down to 8% last night when i plugged it in to charge before bed.
Aslo i wouldnt assume there are "wide spread" issues with the nexus7, for every device ever made there are always numerous threads about faults and the odd pixel being missing, people like to come onto the internet to broadcast there views when they feel they have been slighted or wronged in someway, if there was any "widespread issues with the nexus" (such as apples antenagate issue with the iphone 4) then it would be everywhere over ever tech blog.
Jjust reflash a different Rom
》》》Samsung Galaxy S3《《《
Been down as low as 2% before relenting and letting the poor thing power up. Rooted and on jr5.
Thanks for the feedback all, perhaps I'll try un-rooting it while at 100% battery and see if it fully discharges. Perhaps it's just sensitive about the battery capacity when it changes ROMs/Bootloader status.
My Nexus 7 is doing the same thing at 20%. What happened to yours?
Have you tried a factory reset? That's fixed similar problems on other devices.
Factory reset yes, but not at 100% charge.
Mine dies at/or around 30% - I'm stock+not rooted.
Factory reset it. It doesn't matter what the charge percentage is. I did it to mine and it's working fine
clear your batter stats in CWM, full charge, full discharge, full charge

I tried this and it didn't work for me. The only thing that did was a factory reset by flashing the stock image through the root manager tool.
A user named NeoMagus has received two units with this issue, but I haven't seen many people mention it otherwise.

I'm new to tablets but I returned a Fire with the same problem. I assume it's a freak battery thing and not something innate to this device.
Yup my first C6 and last C7 also had this problem. Charged/Decharged fine for about a week, then just started turning off at about 19-20%. The screen would also display in very small text "show low low battery logo". Re-flashing stock, wiping, calibrating by deleting batterystats.bin, nothing helped, always died at 20%. Just ended up exchanging both so don't know what to tell you guys, everyone else seems to be fine so my only conclusion is bunk battery

Flash back stock ROM, lock boot loader and see if it fix. At this point, you got back your warranty and can ask for replacement

I have the same issue on mine, which is stock/unrooted. I just did a factory reset and it's been okay so far, but it's a little early to tell if it really worked.
**UPDATE** - Doing a factory reset did not fix the issue. It died again after some more use. I'm going to return it to Google.
**UPDATE 2** - After connecting the device to the charger and powering it on again it reported 0% battery. I charged it back up to 100% and I've currently run it back down to 7%. I'm not sure how or why it's working now, but it does seem to be a problem with the software misreporting the remaining battery life.
Mine shut down at 9% last night. Not that bad but not ideal I think it should go to 2-4% or 'go down with the ship' at 0% like my phone does.
Oh well I'm going to get a replacement after my next trip due to audio and touchscreen issues, I've been putting it off in hopes that they iron it out but I can't wait much longer a dead left headphone and random zooming when I scroll is a drag.
Same here ,last week my N7 died at 15% battery
but now at 20% ..
no Low battery Logo show
Should i do Factory Reset ???
Hi all,
First post so go easy :angel:
I've had my N4 for about 18 months. Ever since 4.4.3 (now on 4.4.4 and nothings changed) I think I have been having some probelms.....I also dropped my phone around the time of the update so can't rule out a hardware problem, anyway....
On full charge the phone is, after a random amount of use perhaps around half battery, it drops signal completely....then it start goiing crazy, opening apps clicking on things (sometimes locks up) then shuts it's self off.
Once I turn it back on it says the battery is almost out.....even though before the crash it was at 50%???? (Please see imnage below for "cliff edge" on battery screen shot!)
I have tried safe mode, I have done a factory reset and removed all and any apps except facebook. Other symptoms include forgeting wifi and other account logins!
Also worth noteing I dropped it and smashed the screen, I then had it repaired and voided the warrenty (?) because I needed it same day for work.....dont know if thats connected was working fine for a while after this happened.
I have seen various posts of this forum and other about this kind of thing but no exact answers.....any help would be great 7 months until free new phone
Sudden drop is extreme right....
Re flash factory images for a full wipe, if it doesn't work after that then its probably hardware (sadly), maybe you could get a moto g? I've heard there really good and cheap.

Sounds like something went wrong during the repair or drop and that this is a hardware issue. As suggested, try flashing full stock, but I am pretty sure this is a hardware problem, unfortunately.

Thanks guys .....Ive been doing as much reading as pos.
Some people are saying reather than the drop its maybe just a failed battery? thoughts?
It could definitely be a possibility. If you are up to it, you could purchase a new battery and try to replace it, there is just the risk of damaging something further.

Same things happen to me. I thouhgt the battery is comming to end and orderd new one but I have read that people have some similar problems after updating from 4.4.2
On nexus 5 people also have problem with to fast battery drain. I have similar problems. I lose network, afterwards battery drop from 20-40% -> 0%

Same thing is happening to my wifes NEXUS 4. Hers is a little over a year old now. It was dropped and I replaced the screen a few months ago, but ever since the new updates, her phone has been going CRAZY!
The phone randomly loses signal, battery drains quickly and apps open close (ghost touches) and then it shuts down.
I've cleared the cache, reset to factory defaults and even run in safe mode and nothing. The phone is useless now, she maybe gets 2 hours of normal use out of it before it goes completely nuts again.
One of us should roll back to 4.2.2. and report the result

Facing similar issues. Have posted it here. http://forum.xda-developers.com/nexus-4/help/fast-battery-discharge-t2799931/post53790262?nocache=1
Any solutions?
I am waiting for a new battery. Try rollback to 4.2.2.
ITs same on my phone after an 4.4.3 update teh N4 gone rogue before the update it was working just fine I just did factory reset got back to 4.2.1 android and its doing the same
Just to keep you up to speed...I suspect it may be the battery....or perhaps power management issue/conflict??
Trick is if I keep my battery charge above 60-65% it's fine......get below that and the trouble start.....weird. hvaing said that seems to drain faster than normal also. My hope are pinned on battery solution once Rajnus trys it.
Although not looking foward to taking phone apart to replace it
Today after the first symptom I rebooted phone and after reboot my battery was at 14%. It looks like to me that we have constant drain but system some how is not registering it properly. I will restart after every 10%
Edit: 85% ->reboot -> 57%

I'm glad to see I'm not the only one suffering from this issues as well. I replaced my screen and digitizer about 3 months ago and never had issues. Last week I updated from 4.4.2 to 4.4.3 (and 4.4.4 shortly after) and started having the same issues where there would be ghost touches on the screen once I got to around 70% battery, loss of radio/signal, and when I would restart the phone, I would lose majority of the battery charge. I tried flashing stock back on the phone and the problem still is present.

Just to repeat that is exactly what is happening to me word for word.
Not sure if this is for the QnA section...anyway, yesterday I got a Nexus 7 2012 16GB for my Nexus device collection (used). It was rooted when I got it, with a whole bunch of junk of it, so I used Nexus Root Toolkit and restored it to stock 5.1 (from rooted stock 5.0.2).
Last night however, I noticed two things that seem weird:
- the battery charges really slow compared to my other devices (5 hours for full recharge) and drains quite fast when playing games (compared to the 2013 N7), namely Zombie Driver THD
- self-power off during night charge
While the first one seems normal (it IS used after all so not expecting perfect battery life here), the second one makes me worry a bit. I'm at work so not sure if the issue will repeat, but the battery was certainly not dead when I plugged it to recharge but the tablet was switched off in the morning. Using the original N7 2012 charger by the way.
Any chance this can be ROM-related or is there any known problems like this?
I have had a 2012 N7 in the past but in Android 4.4.4 I didn't have the self power-off problem, maybe a 5.X bug?

Takes me 4 hours at max to charge it from 0 to 100
How much does it last on gaming? I can play heavy games for 1.5 to 2 hours, thats about it. No kernel/rom has given me more than that. It's tegra 3, don't expect much from it.
Some users have reported that bug on 5.1 I however did not encounter it. Although I used 5.1 for just about a day and came back to 5.0.x for xposed

I just came back from work (roughly 13 hours away), the battery seems to be at 97% (no WiFi on) and the tablet was not turned off.
Guess I'll monitor it for a while longer, though knowing how much I plan to use it, it might take a couple of days before I drain it enough to warrant a recharge so that I can test to see if the charging turns it off.
So I thought the issue fixed itself, but last night I found out more about it.
So I haven't used it for about a week or so, it was fully turned off with a charged battery. When I tried to turn it on, it wouldn't work even after multiple tries. So I thought maybe the battery is screwed, so I plugged it in the wall, but no battery charge indicator showed up. I waited a couple of minutes and tried to turn it on but it didn't work, so I left it there "charging". About an hour later I tried it again and it worked, battery was at 100%, so I left it on overnight and it hasn't powered off on it's own.
Anyone can advise on this? I'd just go ahead and re-sell this one, but it's in great condition so I'd prefer to keep it if it's fixable.
I've had a few random power offs or maybe lockups on 5.1? Not sure entirely if it was powered off or locked up, I'm running Complete stock unrooted

Complete stock here as well.
I decided to downgrade it to 4.4.4, we'll see if that fixes it (I'll report back when I believe I tested it enough unless someone gives a known solution or suggestion).
I think you should try installing a new battery if KitKat doesn't fix it.
Has anyone noticed the battery percentage on their replacement note 7 stuck at 100% when it should be around 30%??

Stock phone not rooted. Only think I have aside from a few apps is nova launcher. Android version 6.0.1. Thanks for the reply
I did notice weird spikes on the battery graph. I have actually had it off the charger since 6:10 this morning. At one point I did plug the charger in for about a min. to see if that would reset it after trying to reboot the phone a couple of times to see if that would work. Apparently that just reset the battery stats. I'm really confused because I've been messing with it most of the day playing games,youtube,xda and music just to see if I can get the battery to drop or die. It just keeps on going though with no sign of any battery drain other than a little lag here and there. This phone seems to not like more than 3 apps open at once before it starts to lag.
OK so around 5:30 the phone died. I plugged in the charger and the battery icon you get when there's not enough juice to turn on the phone showed 0%. I waited til 15% and turned the phone back on. It seems back to normal now but we'll see when it gets to 100%
I think the AT&T update for the green battery messed up the phone. I'm hoping the September security update will fix the issues.
I think your right. 2nd battery cycle since the issue and all seems well. Thanks
I had a weird thing happen. My device was off. I plugged in the charger and battery immediately dropped from 90+ to 15℅ then showed a red triangle briefly.

I just read through the thread to catch up. I dont think it's the update because most of us have it (myself included), and are having no issues (reported anyways). Many of us replaced our phones though.
First, do you have the fixed Note7, or the defective (combustible) one?
Second, if you have a fixed version, you may have a bad battery and should get it exchanged as a defective unit.
If you have the version that was recalled, then yes, this may indeed be the update's fault, but at this point, I wouldn't expect it to get fixed. It could be some sort of glitch caused by some safety procedure implemented in order to prevent to batteries being charged completely, or something. Who knows.

Hello and Happy New Year to all,
*
I came across an issue with my Note's (N910C) battery today and I would like your opinion on it.
*
A quick background:
*
The phone has never been rooted.
9-10 months ago I downloaded an official firmware (6.0.1) which I flashed via Odin and it began to drain the battery very fast, killing the phone in less than a day.
I got a new battery, but the problem was still there.
Eventually I tried another firmware which worked nicely and consumption returned to normal levels. Since then, I had no problems whatsoever.
Yesterday night I got a notification to update. I had already done another two in the past - if I'm not mistaken - , without noticeable difference.
I did the update overnight and I removed the charging cable in the morning. It seemed that it was a little warmer than usual, but I did not pay attention.
The battery percentage was reducing at the rate of 1% per minute and it died within 2 hours.
I checked battery info, nothing abnormal.
I have two questions:
*
1. Does anyone have similar experience with this model (or other)?
2. If I reinstall the previous firmware, normally the problem should be fixed, right? I mean it started after an official update which AFAIK affects native apps only.
*
Thank you in advance
I have noticed on my Note 4, after upgrading to marshmallow, the battery drained like crazy too. It would drain 10-20% when I use it for 20 mins or so. The battery that I'm using is a 'new' one that I bought just about a year ago although the problem still occurred when it was fairly new.
I'm speculating that there might be some sort of battery or software issue with marshmallow as the original battery that came with the phone also had the same issue. It would drain fairly quickly until one day it just stopped working and would boot loop until I plugged it in to the charger.
Ever since marshmallow, I have never seen my battery get to 15% before switching off completely. Sometimes even 45% lol.

I had a faulty N910F and got another (used) one and it's had occasional forced closes at between 15-20%. This worries me that it might go the way of the old one where it developed the issues with it freezing and the frequent reboots....does yours exhibit any other issues?

Yes. Unfortunately. Currently, it would just die halfway even when I'm at 50%? That's the highest that I've noticed. So I had to charge it up for a bit maybe to 60% and it would be fine before dying around the 20+ - 40% mark. Previously, the original battery that came with the phone had this weird issue where the battery won't hold any charge even when it's fully charged. Like it will go to a bootloop when I've unplugged it even though it's at 100%. When I bought the new, current battery I noticed that it would still die off at 15-20% and the original battery became bloated a few months later.
Are you using any custom roms? The bootloops and freezing could be related to using some custom roms. I changed from a N7 port to a deodexed stock rom and the frequency of the freezing and reboots just plummeted. Reboots only happening when the battery is close to dying.

Ah right, so you had only the reboots, nothing else? That's fair enough.
No, it's nothing at all to do with the ROM. I'm stock but LOTS of people have had the same issue. As it stands, the only way to fix it is to get a new mobo :crying:

Well besides the usual overheating that's related to our snapdragon CPU, nothing much but mostly battery issues.
Although there is thread that I'm following that promises to fix the 15-20% issue. Checking their method to see if it works or not

I had a similar problem with fast battery drain - did a factory reset and it's back to normal. Make sure you're using a battery from a reputable source like RavPower (don't think there are any genuine Samsung ones left and Anker stopped making them).
