Just found a problem which happen several times on my Nexus 7.
When the battery is about 17%, my Nexus 7 will be turned off automatically like the device is out of battery.
I can't turn it on unless I charge it. After I charge it then I can turn it on. However the battery is still 17% which is the same as when it turned off.
I am wondering whether you have the same problem before. Thanks.

However I remember some 3rd party battery apps show correct info despite the info under settings.

I think this is because android OS is designed to work as a mobile operating system (not turning it off unless there is no battery) so that's y after using ur tabler when u turn it off it resets the time or add a significant difference.
I don't turn off my tablet and most of users don't so that's y ur only having this problem.
Besides tangby time on nexus 7 is amazing 1%-2% drop in 12 hours.

The only time that Android should be resetting battery stats is when you unplug the device after an approximately full charge

Did anyone get to the bottom of this?

I purchased a nexus 7 recently,updated to 4.3,locked and unrooted as of yet. I currently have 2 user accounts active on it. Since my first 100% charge, I have been getting tacky battery life. I follow the 100% charge and discharge till 1% method. Overnight with WiFi on and all apps closed,I'm getting a drop from 74% to 57% . Looking in the battery stats doesn't help as it doesn't show any unusual ongoing background activity. I'm also getting around 6 hours Screen on time,I could never exceed this mark. I only have the customary Google apps,Facebook,Twitter, instagram,pulse,and 3 games installed. What can be the reason of this ?

Those apps keep running.. Also some third party apps push ads and also turn screen on, which could drain battery..
For better battery life, you can turn wifi off if not needed,.

I tried with WiFi off one night, I got around 9% drain still. I kept the sync interval at the maximum in every data fetching app I have installed too.

You might well try the app Better Battery Stats, and see what it believes is keeping your tablet from going into deep sleep. 9% drain overnight is not terribly excessive -- it should be more like 5%, I guess.
My 2012 nexus 7 had 51% before I went to sleep last night and when I woke up this morning it was completely dead. I didn't even get a charge icon when I plugged it in to charge. I had to leave it for an hour then tried again and it fired right up.. Hope I can see what's causing the drain with better battery stats

I was using mine once in the morning,when the battery hit 4% it suddenly shut down. I tried to charge but the battery icon wouldn't show up. Started it finally using the tips on the Google support site. Must say,I've been plagued with battery issues. I'll try a factory reset and while on it unlock the boot loader too.

I checked with BBS with WiFi off overnight. "PowerManagementService.wake lock" is keeping my N7 awake. Any solutions?
EDIT: I checked in partial wakelocks,AudioOut_2 was the highest at 30m runtime.

My friend recently bought an imported nexus 4 from eBay(on my advice). He's having a strange a problem. The device works normally till the battery drains below 50%. But then it suddenly turns off and doesn't turn back on again. When he connects the charger, it's stats charging from 0% again. The charging process is also normal.
Anyone had this type of problem?

Whats the rom and kernel?
Sent from my Nexus 4 using XDA Premium 4 mobile app
Try charging it to 100%, disconnect charger, reboot and check if it already lost some charge during reboot. If yes charge full again.
I had something similar (not a total drop, but a fast drop when below 50%) a few days ago and this helped. I don't know why, though.

I think you should try both suggestions.
Also inform us what is the ROM and Kernel he is using.
Keep us updated.
I have a Nexus 4, I got it when it first came out and then the screen cracked. So, I got the screen replaced, but then got a battery problem - it would die around 50% and be at like 10% when I turn it back on. I got a new battery, put it in and the same thing is still happening.
It's completely stock. The Nexus 4 I'm using right now is completely fine running PAbeta though.
Does anyone know how to fix this?

I am a newbie. I've just got my nexus 4 yesterday.
A few questions:
I am using the Nexus 10 charger to charge my Nexus 4. Is it ok?
Should I charge my phone when the battery goes down to 15%, or should I let it drop till 0?
Yeah your 4 wont use it to it's full potential but its completely safe. Also it's better not to let it drop to 0 but it wont do any harm if it happens occasionally.
