Hi,
My battery info screen is always showing 0% - Unknown. I´ve tried different charging options but with no success.
The battery is charging and when I connect the Nexus 7 to the adapter/pc is says charging - 0% when locked.
Any help is appreciated.
Thanks
Had the same problem. It was not ROM specific. Even though the reading said 0 it was still charging normally (as far as I could tell).
I called Google (I bought my Nexus 7 from the Play Store) and they replaced it. I think that the battery sensor was bad.

Charge your battery to 100 percent, for the best that you can assume as 100 percent - about 3 hours, - and then run this program https://play.google.com/store/apps/details?id=com.nema.batterycalibration root required

Reflash kernel
Just to let everyone know I tried both that app and clearing battery sats in CWM, neither did anything. I even ran it dead and then fully charged with no change. The OP may have a different problem but in my case I definitely think it was a hardware sensor issue.

Um, weird, I came home after leaving my tablet on my desk all day at home, with about 35% battery.
It was dead. Like really dead. Dead dead. I don't know if it should've run down 35% totally idle; I'd left it for 3 days before without a problem.
Now when I plugged it in, it turned straight on. Google Screen -> Lock Screen. No colored X.
Showed 0% for 10 minutes. The battery graph was especially weird. For one thing, it had locked the stats and showed as still on battery basically. For another, it showed going from the low end of green to instantly dropping to 0%, red. Unplugged it, and it died instantly.
I'm letting it charge now with it off. Quick power button press shows the charging indicator thing.
I actually have an RMA out for this one for the touch screen issues, so it doesn't matter, but still... weird.
battery sensor/calibration issues
Old thread but I thought I'd add to it for other people with the same problem.
I have basically have the same issue on a stock, rooted 16GB Nexus 7. It's highly intermittent.
It first reared it's head about a month after I got the device (in Aug 2012), on the original firmware. My nexus 7 wouldn't (appear to) charge past 25% and would shut itself off after being on for only a few hours. I spent a day trying to fix it, including wiping the device, but nothing worked. Then magically, a few days later, the problem was gone.
The Nexus 7 worked fine for another month or so and then one day, after having charged it for several hours, I noticed that it was reporting a 0% charge. (Firmware was still stock but had been updated) This time it didn't power off, it just misreported it's charge. I could still run it for 10 hours or so, even though it said that it had a 0% charge and that I should connect the charger. I tried the "battery calibrator" mentioned in this thread which didn't seem to work but the next day, the device reported it had a charge. It's been randomly fluctuating between reporting 0% and a having charge every since. Sometimes it works fine for several days but then it will say 0% again.
It hasn't really affected my use of the device but it can be inconvenient not knowing how much charge you have left. Today I finally called Google and explained the problem and they promptly offered to exchange it. Hopefully this is not a design flaw but a faulty component from bad batch..
There's more than a good bit of bad advice in this thread. That anyone would waste people's time by recommending a ”battery calibration” app or to wipe battery stats is disheartening, as it is widely known that they have no correlation to battery indication.
More often than not, it seems, this problem with the N7 involves the battery connector not being properly seated.

I'm also having a similar problem, though when my nexus 7 completely dies from the battery I plug in and right away power back up and when it comes to the home screen with 0-1% charge it right away powers down. I tried leaving it off while pluged in let it charge for 5 mins and then power back up again till I see it have a minimum amount of charge, it seems to work not sure if its ROM or kernel related, I'll keep an eye on it.
There's a helpful article that seems to help other nexus 7 users, hope this helps

I have the same problem with my nexus 7 3g.
Factory reset does not help.
Finally open the back cover (quite easy) and found that the battery cable connector is loose. So I tightened and my tablet is well again.
Hope this help.
Yeah what worked for me was to also unplug my battery. Seemed to correct itself after that. Mine would shut off showing a charge of 60%.

Does the back just unsnap like a regular battery door?
I have issues sometimes. Like the other night it charged all night and when I woke up it was fine, turn off the alarm on it and had breakfast. Came back and it wouldn't come on. Tried all I could without taking it apart. Ended up removing the back cover, unplugging the battery for ten seconds and then it worked fine. Battery was at 100% once it booted up.

Use your fingernail to get between it and the chassis. It pops off pretty easy. Just be careful. I'm sure YouTube has a few videos showing it.

Hi.. I Have the same model and I had the same problem...
I made the turn off method (https://plus.google.com/+DerekRoss/posts/563EVVEPMDS) and did not work...
I rooted my Nexus to calibrate the Battery (http://forum.xda-developers.com/showthread.php?t=1838429) and did not work.
But the in my case the most simple solution works : Unplug /plug the Battery (http://productforums.google.com/forum/#!msg/mobile/Knrn4DThksg/ovuWYHUytZ0J).

A few weeks ago, i flashed a stock rom on my wifi nexus. I was happy with it until last week. Charging became incredibly slow - 30% over 8 hours. I threw it in my bag and wheb i got home 8 hours later, the battery was depleted completely. I couldn't turn it on. I plugged it in over night and it stayed at zero percent. I booted into recovery and reflashed my stock rom abd wiped my data. Still didn't charge. I tried going into my bootloader and hitting power off and then plugging in, but it still wouldn't charge. I can't flash my backup because it's on my card that i lost, and even if i had it, i wouldn't be able to keep it on long enough to flash it. ADB won't run on my pc and i don't know how to use the program anyway. What can i do to save my device? Please help.....

Not the average flasher knows how to tear apart a device - including myself. Anyways, this thing won't power up at all? You tried leaving it plugged in and booted into bootloader? If so, sounds like a hardware issue or the battery is defective.
I would be willing to bet that your battery connection came loose. Start at your USB port with a thin piece of plastic, such as a guitar pic. Work your way around the device and remove the back.

I heard that was a good site. I'm more scared of screwing up any hardware than doing the actually tearing apart.
I can boot for like 30 seconds and then it shuts off. I've tried the solutions in the thread link above; however, i still think it is a software issue. I've used other roms that had really slow charging, but i was able to switch to another one before the battery got depleted. So i think my best bet is to somehow get a new rom on my device somehow. ADB won't run on my computer. It just flashes a command prompt on the screen for like half a second and closes.

What kernel are you on? The kernel is what does the charging operations.

I had a similar situation in that after the battery died, I got it to the point where I could boot up, but after a screen timeout, it would be dead again. Finally, I got it booted again (while plugged into power) and immediately went to developer options and checked the Stay Awake, never sleep while charging. Keeping the screen awake kept the N7 on and it charged up.
Funny my Galaxy Nexus started doing this crap on me too after I updated the rom and kernel. The phone and battery are only 2 months old replaced in April.
Occasionally it won't take a charge. I have to **** with the battery, removing it several times. Then all of a sudden it starts charging again after 10-15 resets.
Haven't had a problem in a while. Typically hits me like every 2 weeks.
No problem on N7 though but it happens. First thing is to change your kernel and rom to something else. If still draining, flash stock and relock, unlock, relock, wipe. Boot, upgrade to 4.2.2 and test.

Hello, :fingers-crossed:
i'm having a lot of troubles with the battery of my Nexus 4. I'll try to explain this strange situation...
Few days ago i noticed a ridicoulous battery drain while i was, as usually, listening to some music with my bluetooth A2DP headset Jabra HALO2. It was something like 1% every less then 1 minute. At first i thought it was due to a recently upgrade to CM10.2M1 (which is a monthly build of Cyanogenmod on 4.3) or due to a 5 minutes fast charge from the 2A charger of Nexus 10 that could have "upset" the battery.
At first i started focusing on the software side problem; i tried CM10.2RC1, CM10.2, stock 4.3, stock 4.4 and now CM11M1, and, while doing all of those wipes, i noticed that not only the discharge was insanely fast, but even the charge! The graph on the setting panel is almost vertical while cahrging, like 3% to 40% in 25 minutes.
But that's not all, sometimes, after rebooting, i noticed a battery level different from the previous boot, so i decided to wait a full discharge and then fully recharge it. I have waited the 0% (not so much time ) putting the screen always on and the LED flash too, then, i tried few times to turn it on and every time, after the boot screen disappeared it immediately started to turning off due to 0% battery.
Moreover, for being certain, i tried to turn it on in recovery and wait how much time it would take to consume the lasting charge on the battery. Surprisingly, after 30 minutes it was still there! I tried a reboot into system, showing me a 10% remaining battery (WTF), which discharged to 0% in like 3 minutes. Now i'm waiting the whole night the real discharge in recovery with screen always on, hoping that a full recharge could fix it. I would like to evidence that the phone do not overheat during both charghe and discharge, so i guess the battery itself may be ok.
I'm still not sure if it's a software problem, and i'm worrid if it could be an hardware related issue. Maybe it could have been the charge from the 2A adapter.
I really don't know what to do next. Someone knows how to help me?

EDIT:
I've done a full discharge until even the full hybernation has been shutted down, but seems that it hasn't solved anything. I've also noticed that in the battery stat is missing the display consumption (WTF?!?). Maybe it's a CM11M1 bug, it happen even to my Nexus 10. Here other shots:

EDIT:
I've noticed just now that while I was waiting a real full discharge of the battery the TWRP couldn't show me the battery percentage. Really strange...
[SOLVED]
In summary, the problem was the combination of kernel+ROM. The CM with his kernel on N4 was consuming tons of electrons. I tried Purity+Hellscore, now i reach few days of low usage and one and half of medium usage

It have 9 months, and yes is still under warrenty, but I've bought it in Spain, and I live in Italy. I think this will be hard to solve
I have some strange problemi too.
Sometines the phone reboot itself and the battery drops (i tried to flash all stock: recovery, bootloader,ROM ecc..)
It could be a faulty battery.. Read this topic, it looks like you have the same kind of problems.
Do you also have simlocks/loss of network connection?

I've already read this topic, i think the source of the problem may be related with mine, but symptoms are different. It is strange that this happened 9 months later!
Gully discharging the phone, rebooting, discharge again if any, reboot. Connect charger, charge full. Reboot, charge full again if any, reboot. This always worked for me.
You can also try to fully discharge, completely power off the phone and let it fully charge while powered off ( only a white battery should be shown on the display).

Hi all!
I've some strange problems with mt nexus 4 battery values.
Today i had 59% of battery and i plug it to the original charger. After 2 hours i saw the battery with 100% charge value. OK. Nothing wrong here. I rebooted the phone and after that i had 84% of battery.
This is happening almost every time i charge my nexus 4.
I had stock rom with franco.kernel updater. Now i have paranoid Android with The same kernel.
Any idea about this?

Have you been dirty flashing a lot?
your battery reading needs to be recalibrated.... Charge full than use until it shuts down...than charge again fully, at 100% reboot phone & connect to charge again.....
You also can try "BatteryRepair.apk" from market..most of the time it helps to recalibrate..just install, open & follow on screen instruction....

I had the same issue with my previous nexus 4. Did you ever get your screen/display changed? Or do you charge your phone overnight? Do you rely on USB charging a lot? If any of those answers is YES, its probable that your battery has gone bad (as mine had)
I don't think that's the solution, but give a try to this free app from the play store: https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=it
I always thought this problem was related to rom development but I'm not sure. It happened to me with CM11 at the very beginning in november, and then it just stopped. Since January I'm on slimkat, at first it didn't happen and then for a few weeks i noticed the same problem you have, now everything has been fine again for the last two weeks.

Just try avoiding the charge to 100%->reboot->charge to 100% again for a few days.
Don't let it discharge till 0%, connect the charge when you have 1%-4% left and let it charge till 100% with the phone on, and then use your phone normally.

Please go through this thread. A couple of other members (myself included) finally deduced that if you ever have your display changed you NEED to get your battery changed as well. Trust me on this, get your battery checked once. It WILL be bloated. Also, if upon restarting there is a break in the battery graph and there is a significant drop/rise in battery level, that is another indicator that your battery is going.

I've been reading that thread but for example, what happens to me it's nothing compared to the first topic of that thread. I only miss sometimes 10% after restart, sometimes 5%, sometimes nothing. From what i understand, in that thread most of users with battery problem had like 80% and after reboot they only had 2%, or 0%. Thats different i think, but i'm not expert on this subject
Anyway, installed the suggested app and calibrated the battery throw the app. For now i have this data (Paranoid Android Beta6+Franco.Kernel.Updater r201):

Try Battery Monitor Widget from the Market - you can see what current the phone is pulling, and if indeed full charge is reached. There are also calibration tools inside - the app calculates the real capacity of the battery, for example. If it's a long way from 2100mAh it would be a sign you need a new battery.
Though like everyone else, I think it´s a software problem. With previous Android phones I had to be careful calibrating, flashing etc. With the N4 I've had no such issues in the year I've had it. That app can help you sort out battery calibration though.
Can you tell me The dev name? Got 2 battery monitor widgets :s

This looks normal, although if you see a break in the battery graph and huge drop/rise in battery then its definitely done for. However its not the case with your phone, so relax
Well this evening i left the phone with 60% of battery and at 7am the battery was death. Just ordered a new one. I've only one problem. I dont have any plastic screw to open it. I've the torx t5 screw only.

Hello,
My N4's battery has been behaving really weird over the past days. My phone completely fails to predict the battery's current charge and it often would shut off at for example 40%. When I reboot it's at 0% charge and shuts down again. The battery at that point is 'completely' empty. Which means that even date and time have been reset!
You can see the sudden battery drop here:
Stats (after few minutes on charger):
The weird thing is, that although the screenshot says 4h runtime on battery, it was running more like 8 hours at that time.
The screen time is also calculated completely wrong. It should be more like 2 hours, but it says 43 minutes:
Besides that, it happens often, that I unplug it after a night of charging and while it says 100% while still plugged in, once I remove the cable it drops to ~90%, sometimes even lower.
This was today morning after a night of charging (same day as screenshots above). Mind, that I had to replug it to achieve 98%, after I first removed it before showering it was at 91%.
I'm running Franco Kernel and Mahdi ROM. Though the problem exists on other kernels and roms as well.
Should I revert to stock and completely whipe everything? The only thing I restored from Titanium Backup during Rom switches are user apps and wifi networks. So I wouldn't consider it dirty flashing, right?
I hope the battery itself isn't damaged, since I get a maximum of 2 hours OST, where a week ago I would get around 3,5h-4h..
Thanks for your input.
Edit: Forgot to say, that another problem is, when using the wall-charger, it would tell me after 20 minutes charging from 0% battery that it's at 100%, while after a reboot it again shows only 20-30%.
try using xposed disable battery critical shutdown to recalibrate the battery
if dosent work -> rma it.

Thanks. As it has shut down again after about 3h on battery (1h of usage) I've noticed a relatively big buldge on the back of the phone. I think the battery somehow popped
I have absolutely no idea how that happened. Will write to the LG support now.

Return To Manufacturer, looks like your battery is worn out. If your N4 is over a year old you'll need to buy a new battery.
