My battery is stuck at 100% and won't go down. Normally I'm not complaining about battery life in this way, but this is really weird. I'm running Paradigm by the way.
Fully charge your battery, then wipe your battery stats in CWM. If that doesn't work, then it's probably an issue with the ROM.

That didn't help, so I flashed the euroskank cm10 nightly, and I still have the issue. Ahhhh. I don't want to have more issues with this tablet. Any other recommendations?
Go back to completely stock and see if it works. Then you'll at least know if it's software related.

I'm now stock unrooted, all set up. I'll run stock for now until the new Paradigm hits. Then, I'll try rerooting. If I run into this issue again on stock then I'll call Google, and probably just return it. I don't really want a third one. BTW, when it happened, recovery would also show 100% as a reading, but would usually go down to 99% after a while, and then when I rebooted, it would discharge at a normal rate, but would never compensate for the weird extra time at 100%. Does this point to a software or hardware issue?
Is it plugged in?
Lol no. It says discharging, 100%. But my screen was on for 31 min, and it said that and I'm pretty sure the n7 isn't rated for 30+ hrs screen on time.

I'm fairly sure 6+ hours with the battery still at 100% is not normal, unless it was asleep the entire time.

majority of the time, i was busy at work. but, ive seen and some other people have seen 2+ hours at 100% with use. so, depending how long hes been watching it drop, it might be normal. especially since he said he saw it drop in recovery then drop after he booted up.
As I said earlier, battery was at 100% for 31 minutes of SCREEN ON. Then I rebooted, cleared caches, hung around in recovery for 5-10 min, saw it hit 99%, rebooted, and system said 99%. Like I said, that would mean I could get 30 HOURS of screen on time. NO WAY is that possible.

that doesnt mean that you would get 31 hours. what you just described is normal and youre freaking out for nothing.
Maybe you have a super battery saving kernel try just to run it flat, then do a charge while the device is off

my first day with the n7.. happy now? i ended up getting over 7 hours screen on time. you cant extrapolate 30 hours from it that way like you were doing.
This happened to me too.
After taking it off the charger it wouldn't go down. Now keep in mind my case I had left it overnight and hadn't played with it so I had at least a day in my battery info on 100%. Rebooted, then tried factory reset, all the normal stuff to try and nothing. Then tried CWM wiped everything then even reflashed the ROM and tried a different kernel after going back to complete stock it started decharging finally but now dies at 20%. It just turns off doesnt even shut down, and when it finally gets enough juice to start it would flash a little text message in the upper left "show low low battery logo". I finally managed after flashing CM10 then back to stock and charging and decharging a few times and deleting batterystats.bin from data and pulling the charger while it was booting to get it to realize there was an inbetween 0 and 17% and it sat charging for a while on 0, where it had just jumped straight to 18 but is now charging up normally again, that is where I am at.
I've got like 3 days left on my exchange with GameStop and I'm back and forth whether I should just take it back because I don't have any of this screen lift banter every talks about but don't want to end up with a faulty battery because it only just started here like last week.
People, the nexus 7's battery is not that good that it can go for hours without dropping 1%!!!
It could be that there is a problem with the battery indicator. That could be hardware or software.

yup. remember, theres no 3G/4G radio sucking the battery juice dry.
Well, flash all stock, and watch the battery meter.
Flash a custom rom with stock kernel and watch the battery meter.
Flash a custom rom and a custom kernel and watch the battery meter, what do you get?
FYI, look at the screen on and total time at 50% battery, i bet you won't have double those time by time you hit 1% either.
You can't look at the first 30 minutes and go crazy over it. That's as bad as watching wakelocks and going crazy over wakelocks before you have an issue, wakelocks are normal and needed.
Stop obsessing, enjoy the tablet.

Ok.....I read all the batt stat related post and I tried every single ways to extend my batt life.....here how I did
1. charging the phone more than 5 times when the phone is on.
2. turned off the phone and charged 5 times until 100 %
3. turned it on again and charged more than 5 times
4. then I did batt stat by using terminal emulator
5. then I charged again while phone was on for about 3 times
6. turned off the phone and charged again for 3 times
7. then I was using my phone and I let it die by itself
8.then I fully charged the phone
theses were the steps that I followed and my batt life sucks...like when I was using internet it drops every 2~4 minutes.....even though I dont use internet just playing around with the phone It drops that quick....I am very shock that some ppl are using the phone more than an hour and still its 100% gauge....its so amazing..i really wanna do that too.....and Im currently running SC2.8 non voodoo.....do I need to use voodoo to extend my batt life????
Any suggestions will greatly greatly greatly!!!! appreciated!!!!!!!! plz help noob out...plz......

umm....for the screen it takes 80% of the batt usage
and rest are just random stuff (about 4 different ones but they were only 1~2%)
I went to the movies at 2pm with 100% charge, I listened to online radio for 20 minutes on the way there, watched the movie and now its 7:30 and my phone is at 5%... Nothing is running in the background and my phone was in the packet the whole time.
Amazing that I can play angry birds on the iphone for 4 hours during my daughters recital and still have 30% battery left and this stupid samsung pos cant be on standby for 6 hours.

Do you have screen brightness set to "Auto", 80% is to much for regular use.

Was having weird issues myself (signal/Internet/battery).
For ****s and giggles I gave the DL09 radio a shot on EB01.
Have had really nice results the last couple of days.
Never made it to 4 hours of screen using the Internet before.
And it still had more.
good day.
it sounds like you are both experiencing a bad battery, or a very poorly set up phone. use auto brightness or manually turn down the brightness. make sure you don't leave apps running with the screen off if you can help it, and keep your radios off when possible.

To do proper full battery calibration just for one single time required a minimum of 20HRs, that's what needed for 3 full charge and recharge cycles.

Reset battery stats one time at battery full reading, then discharge and recharge for 3 full complete cycles without wiping the stats and you're done calibrating (~20HRS).

You can't just check battery status. You fully charge. Then use phone normally till its almost empty. Then check.. Then you will see a proper representation of where you battery is going

oh and I was using my phone for 19min and my batt percentage went down to 95......and this is my second cycle to charge and die
I've had my phone for about a week now(att unrooted) and experienced something very strange this morning. I fully charged the phone at around 5:30 last night and used he phone very moderately. At around 11:30 pm uploaded 3 photos on my google drive and the battery was 80-90%. Woke up this morning and the battery was dead. This is totally out of the ordinary because I never experienced this before even with my old and buggy captivate. Keep in mind that I was on wifi and the phone is not yet rooted. Has anyone else noticed anything like this?
That is strange. Honestly, I dunno what could cause it besides some random app that you installed.
i say download a battery calibrator and then go from there

Battery Calibrator won't do anything.
Install Better Battery Stats, and when your phone turns on after plugging it in, see what was using the most power. It won't work for the first time but will work in the future.
Even better uninstall ****ty apps and disable notifications on this like word with friends, scramble with friends, etc. Go into app manager and disable everything you don't use. Report back in a week.

I've had the phone for 5 days and gone through maybe 8 batt cycles. I'm not getting more than 2hrs screen time on any cycle. This is stupidly horrible battery life. There has got to be something severely wrong. I don't do much with the phone. I can't even with less than 2hrs to work with. Overnight batt loss is maybe 8%.
Any help is ENORMOUSLY appreciated.

Update
I was able to reproduce something similar. I opened up market\play to do a few updates and once the update process started, I put the phone down on my desk. Updates installed and the screen remained turned on. Now, I don't remember the exact steps or what other apps were running in the background. All I know is that the screen remained on for a few minutes until I manually turned it off.
This could very well be a bug in Samsung's face\image recognition software that handles smart stay. It might be a bug in google play, a faulty app or a combination of things... Because the battery on this phone is actually quite amazing. I unplugged my phone this morning, went to work, updated a bunch of apps, saved local maps to google maps, hung out on facebook, surfed the web... and after 10.5 hours, I still have more than 50% battery left.
That's a good indication that what I'm experiencing is a software glitch of some kind that if left un-attended, could completely drain your battery.
Try turning battery saver on and check pretty much everything in there. Disable smart stay. Manually turn off your screen when you're not using it. Turn off GPS, Bluetooth, and WiFi when you're not using it. Some downloads hang in the Play store if you "update all"... cancel these and download them one at a time. Do not just assume it all went to plan.
These tips on combination with my first post should help. You should get 4 hours of screen time with some phone calls in a single charge. I find certain apps like Scramble with friends chug charge faster than things like reading xda. Chrome for instance on the PC is less battery friendly and more resources intensive than IE. Perhaps the same is true for the mobile version.
There are way too many variables for us to pick out what your underlying issue may be. Start eliminating things and we'll keep throwing out new ideas. Good luck!

I have managed to narrow it down.
- I had 2 updates in market. I pressed update all.
- screen turned off when the first update was almost done.
- I pressed the power key and entered my pass to turn the screen on and left the phone on my desk.
- I kept seeing the smart stay icon, but the screen remained on.
- I moved phone without touching the screen...no change.
- held my hand over the camera at a distance of a few inches and the screen finally dimmed out.
This happened while google play had focus. This is a bug in smart stay or google play.
Somethings definitely up, this battery life is as bad if not worse than my epic 4g.
Did notice one thing... I cleared memory and it said 51 applications closed.... I don't even think i have that many applications on the phone!
Memory eats up a lot of power.

You're the second person I found that has the same problem as me! I can't even get 2hrs screen time through my day to day. The same day to day that my atrix was giving me 3.5hrs on.
I feel better knowing that I'm not doing something wrong, but could the phone just have that horrible of battery life and all these reports are a fanboi lie with review articles just copying each other?
I'm so glad im not the only one experiencing all of this! Lol, i upgraded from my mytouch 4G, i DID notice smart stay would come on at random times, sometimes when i wasnt even looking at my phone lol, disabled it & disabled a whole bunch of other crap & like many others & i dont get 4 hours screen time, more like 2 which sucks, id also like to have my data on all the time (but im forced to turn it off to save battery ), im rooted & ive uninstalled w.e crap i didnt need/want or felt it was just running for no reason. I'm doing the exact same battery steps i did with my mytouch & its sad =/ i was hoping i wouldnt have to do half of the ones im doing now, i LOVE my S3 but samsung needs to figure out wth is goin on & same with the guy who talked about if the articles r lying) i saw one on tech radar yesterday on battery life on the S3, they r either lying or they got a good phone in a good batch, smh, also experience my screen flickers from time to time while texting (i always close background processes) i notice blotches on the screen while texting at night or in the dark also, again i love my phone but u know, id love to have my data on constantly to check things quick without my battery going down drastically when i barely even touch it =/
I too have strange battery life. I usually leave my phone charging over night. When I unplug the battery in the morning, I lose about 10% every hour. However, when I get to around 80%, I recharge it again and it loses battery at a MUCH slower rate. Around 2% every hour on stand by. I'm not sure why this happens, but it does.
Also, there are some instances when I pick up the phone and it's pretty warm. Even though it's been sitting idle for about 20 min. Then there are times when I pick it up and it's normal room temperature. This leads me to believe that there are some processes going on while my phone is idle. I'm trying to find out what apps are causing this, as I believe it is causing my battery to drain while idle. It's very inconsistent, which is making it hard to track down. I don't even have a lot of apps installed. Most of it is actually the bloatware that came with my phone

I am starting to think it's ATT's LTE connection. I randomly have days where my battery won't make it until 5 pm without really using it very often. Other days, the phone goes all day with 4 hours plus of screen time no problem. On the really bad days, the phone will stay warm despite me closing every app with task manager. I am now experimenting with turning off mobile data (not a permanent solution), and the phone is cool to the touch again. It may be that the phone is burning up the battery in areas where the LTE connection is weak.

Mine did this as well I think it went up 3-4%.
I have a very strange problem. I can't decide if there's something wrong with TWRP or with my Nexus 4. Here's the series of events:
1) I want to backup my phone using TWRP 2.3.2.3 that I have installed.
2) Battery is at ~58%
3) I plug the N4 into my wall charger.
4) Reboot into TWRP and start a backup, with everything checked to backup, using compression.
5) TWRP shows battery is "58%+" (I assume "+" means charging)
6) A couple minutes into the backup the screen goes dark.
7) I press the power button and get a battery charging symbol. I press again and eventually boot into Android.
8) Battery is at 1-2%
How can my battery go from ~58% to almost 0% in two minutes, especially when it's on the charger?
To make things even more strange:
1) I wait until battery is charged to 100%
2) Reboot into TWRP and start the exact same backup.
3) It completes successfully, reboots into Android, and battery now shows at ~92%
What is going on here?
Slight battery loss is normal upon a reboot. As to your first issue... beats me. I doubt it's a problem with the phone. Maybe a one off.

I'm not so concerned about the battery going down when backing up. I would expect that. Although with it being plugged in you wouldn't think...
But the part where it suddenly dropped to near 0%... if it only happened once, maybe, but this has happened twice when my battery was not at or near 100%. I suspect it would do it every time.
I was just wondering if anyone else had experienced something like this?
As a constant ROM/MOD flasher over the past 2 weeks of having this phone I have not had any similar issues.
Loosing 20-30% at once after doing something like backup in recovery is unlikely, but possible.

What about a 50-60% drop after two minutes of backing up?
If I'm the only one, I might have to RMA my phone.
Try 2-3 times the same scenario, then switch to CWM and repeat the procedure. Then you'll know where is the problem, for sure.

That sounds like a GREAT idea. Thanks, I'll try that. Although I was hoping to use TWRP because it compresses backups, and my N4 is in danger of running out of space. But it would be worth trying just to see if it works.
I doubt you can charge whilst in recovery. I'm sure cwm will not let you charge even of you shat your pants ....

I thought charging would be a hardware thing, so it should do that no matter what your phone was doing. ?? Besides, TWRP shows a "+" next to the battery percentage when plugged in. It's not there otherwise, so...
I've had this issue happen a few times on my i777 S2. The phone would randomly reboot and the battery would drop down to <10%. I've had it happen at an original 90%, 50%, you name it. I chalked it up to issues with the battery.
Ok, so I installed CWM, but then ran into some threads that said it had issues with JB 4.2. As in, it doesn't know how to properly handle the new "/sdcard/0/" folder structure that was introduced for multi-user support. So, I chickened out and went back to TWRP. But then TWRP did another 55% battery to 0% battery crash again. Only when I have a lot of battery left will it actually complete. *sigh* I will try CWM again, at a similar battery level, to see what happens.

So what did you do with that phone? I'm considering an RMA, especially since I seem to be the only N4 owner on here with this issue.
When mine crashes, it doesn't finish the backup and it goes to a blank screen. Only after having it plugged in for a minute or so will it actually start up. Like the battery was completely empty. And it only seems to happen when the % left is under maybe 70%. It's always completed in the 90% range.
RMAing this early in the life of the phone is a waste. How do you it isnt a bug with twrp. I would wait it out for a bit. I also feel nanodroids are over rated. Titanium Backup makes things so easy. Since the bug happens only when doing that one thing it sounds like a bug with twrp.

I can't imagine a bug in recovery that is able to deplete your battery 50%+ within 30 seconds. Another weird thing happened: I was at ~70% and then rebooted into TWRP, which then immediately had the battery at ~20%. I rebooted back into Android and it had the same thing. I didn't even kick off a backup or anything. ??? See the screenshots here to see the two dramatic cliff drops I've had, one earlier today the other a few minutes ago.
I will wait on the RMA to see how things go WITHOUT using TWRP for backups. I think nandroids are very annoying to make and use, but I didn't want to learn how to use Titanium (it *looks* complicated). I think I'll look into that now though.

Do us a favor... There is no issues with CWM & 4.2. Do your CWM checks, don't waste time.

I'm not sure what all the issues were that I was reading about, but one I experienced was not seeing the CWM backup folder when connected to my computer. I like to transfer them there to save space on my phone. CWM puts it in the wrong folder for that in JB 4.2, although I think it can be moved.
I'm looking into Titanium now.
I have to say, as a former iPhone 3GS owner, that Apple made all this backup/restore stuff drop dead simple. Completely and utterly automatic even. Your average user would NOT be able to figure this out on an Android phone.

It wasn't that much of an issue for me since I had multiple batteries. It would happen about once a week. The battery would soon and I would pop in a new battery. Ended up selling the phone to fund my Nexus.

Last night before going to bed I decided to turn my tablet off (it was around 45% battery left). When I tried to turn it on this morning, it was dead; no response. So I plugged it in and after a few minutes it booted up. I went to the battery settings and saw that it dropped off to dead pretty much instantly. Here's a screenshot after charging for a few hours.
Does anyone know how this happened, if it can happen again, or if it was just a random occurrence?
I'm on stock 4.2.2 rooted, and the only app I installed yesterday was "avast!" security to try it out.

Same thing just happened to me only I had more than 45% and was using it at the time. The screen would flicker every time I would touch it and keep flickering for about 3 secs if I swiped to change home screens. Display went dark and was unresponsive. After plugging it in it finally booted and said I was at 0% battery.
OP: it could be a problem with the reported charge left in the battery, or a hardware defect that is grounding to the chassis and then through you that is sucking all the charge out. No app or anything can possibly drain the battery that fast, even at max load and max CPU speed constantly. The only way charge can leave a device that abrupt and by that large an amount is by a short somewhere in the hardware.
Vindico: sounds like a definite hardware problem to me and the tablet should be replaced. As I said above, there is no possible way in all of electronics and physics for a battery to be drained that fast and suddenly with our hardware in any situation other than a short in the hardware.
45% of charge loss in a few minutes is simply not possible without huge amounts of heat being generated... I assume the calibration or measurement is completely off... Or do you see bubbles coming out of your Nexus 10? :laugh:
I've had this happen to me twice, each around the same 45%. Except i must have caught it pretty much soon after it happened because the tablet was really hot each time, and took about 5 minutes of being plugged in before the charging icon would come up.
This happened to me today, and it happened 2 weeks ago.
While I don't have any technical advice to give, I purchased my tablet in December and Google is replacing my tablet free of charge.
Samsungs quality control on this thing has been pathetic. Here's hoping I get a better copy next time.
Cahce?
Have you tried clearing Battery stats? You should give it a shot, I have had a similar problem with my Galaxy S2 & S3.. It was fixed after i cleared the stats.

Probably a coincidence. Android generates battery stats on boot always. Clearing them does absolutely nothing. That is straight from what Google said when it was all the rage to clear your battery stats when flashing a new ROM or kernel years ago.
Well I think its more of a reportage problem... I have this new nexus 10 which is showing the same problem..
Once my tablet screen flickered and went off... And it responded only after 10-15 min of charging...
Now also at times the battery status will get stuck at some particular percentage and wont update automatically however a reboot will set things straight...
Overall battery life is not diminished so the other scenario of battery being rapidly depleted due to some hardware is quite unlikely...
Besides the whole time the battery was stuck at one particular percentage was when i was actively using it and screen was on... So ideally the battery should have drained during this time...
Bringing this back to life, mine just died at 50%

I have the same problem. Battery is 100%, I disconnect charger and then few seconds/minutes and reset. After reboot it stop at X sign and reset again and again, and again.
When I connect charger Nexus can boot but it shows 0% empty battery! After few seconds/minutes battery shows 100% again.
So I think that my battery is broken (or battery controller at least).
In my opinion Nexus 10 has very poor quality during production (reboots, battery problem, heating problem etc.). So I'll never ever buy a Android tablet again, especially a Nexus line or from Samsung. It is unacceptable for me to sell product with so many bugs.
I just charged to full while the device was off and plugged in, and deleted the battery stats. I'll report how it goes.
Sent from my Nexus 10 using Tapatalk 4 Beta
No change after deleting battery stats, still shut down at ~32%.
Time for a warranty.
Exact same issue, 2 days in a row :/ Every time it reaches around 50% it powers off and won't turn back on without the charger :/ What do I do? I only got this on Wednesday!

Ughhh just had this happen to me. Hit 32% and boom shut off. Really lime the tablet but this is kind of a deal breaker. Anymore news of a fix. I'm running AOKP 4.2 right now.

Not sure about an actual fix, outside of a battery replacement, etc.
Mine is currently at Samsung for repairs, which has been "fun". I started by sending it in after describing the problem as "while discharging, the battery will drain as it should to about 50%, then immediately to 0% and the tablet shuts off saying the battery is dead". The original call taker, who was really nice, took it as a "charging problem" and didn't say anything to me. The repair status tracking online just said "component replaced" so I decided to call. Turns out they just replaced the charging port, nothing else. Not going to fix my problem though. So, I re-explained the problem and the nice lady said that she should transfer me to advanced tech support. Sweet! Finally someone who knows the issue! WOOT!! Someone named Robert totally understood the problem, put me on hold, and came back and said "Okay, so, just to make sure we really get the problem fixed, I'm having them replace the whole motherboard, battery, and the connection terminals that the battery hooks to" (I forgot the name). "We're taking the shotgun approach here, so hopefully it'll fix your problem. I'm also writing a better description of the light leak in the bottom corner, and having them expedite the repair since it's been here for 5 days already".
Robert, you sir, are my hero today.

Who did you contact for repair? There was nothing in my warranty book about who to contact. The pay store said to contact Samsung directly for the nexus 10

Okay I had the same problem that everybody else here has had. I have reflashed the stock rom and unrooted and locked my Nexus and everything seems to be working perfectly since then. No more reboots freezes or incredibly large battery dropping since then.

Yes, i do this each morning as i wake up (cause why not), take phone off charger @80%, turn on flashlight and leave it for a minute or so till phone reads 79% (I've found phone needs to be less than 80% to work) once at 79% plug in then instantly power down and boot to download mode (1st screen that loads once button press is initiated) and leave it to charge as i get ready for work....charges to 100% in about 40 minutes give or take.
Doing this I'm averaging 7.25hrs screen on time (20%) so i could get 8 to 9 if i ran down to 5%. Or roughly 7 hrs down to 5% from an 80% charge.

I hope more developers are interested in note 8, I remember the times of note 4 and developers like @OvrDriVE, @TEKHD good times.... ?
First we need to get an unlocked bootloader before we can flash roms

I'm hoping for AOSP based rom, but I'll take whatever I can get. I'm a flashaholic looking for my fix lol
Definitely a flash-a-holic here too. Anxiously awaiting the unlocked boot-load-her. Been running my ancient Note 3 on Lineage for the past couple months waiting for someone to take the 8's virginity. In this day and age I don't feel right committing to a device until I can truly make it mine. I'm her new daddy and she does what she's told.
Great to see we got root and hopefully the bootloader is right around the corner!

When you leave the phone charged that way the screen goes off or stays on all the time while it reaches 100 ?

So that's the work around for getting a 100% charge? That is a deal breaker for me as well. I commend everyone that was involved for getting out this root for the US Note 8. However, I can't but imagine some Samsung developers snickering at the fact that people are rooting their phones while loosing app features, having battery charging issues, etc. Until, there's a Unlocked Bootloader (to which you can use TWRP), the SAMFail root is not worth it to me.

With 80% charge I'm getting 6.5hrs+ SOT and from 100% (download mode charge) getting 7.5hrs SOT and that's just to 10%.
Prior to root and full app install i was getting 6 to 6.5 from 100% to 10%.
Not pushing you to it, just laying out some actual use stats. Root has only made my note 8 experience better.....better SOT, better audio, 3minit battery...list goes on.

That's it right there, I'm not getting 6 to 6.5 from a 100% charge. I'm actually getting a good 9 hours from a 100% charge. I've had all my Android phones rooted in the past, including my iPhones. None of them I had to lose having a full charge, not being able to use apps because of root, etc. Who wants to put their phone in "Download Mode" everytime to get a full charge? Lol, in "Download Mode" you can't answer calls, send or receive texts, etc. Really?! It's just not worth it. Fortunately, I'm able to get away with using my cracked apps like AdGuard which blocks advertisements on my phone is my main use of root amoung other things. I can live without SamFAIL. Until you can put TWRP on your phone, its just not worth the hassle.

Well since i lack the FOMO any missed call or text will try again so to me its meh....to you it may change your world.....i would fear that too if it was the case....You shouldn't root until and if bootloader gets unlocked.....
I don't think this will work after today's new bootloader software update. I believe the new update breaks root.
