My Nexus 10 is shutting off with the battery status showing 3% and won't turn on until the charger is connected. How does I recalibrate the battery meter?

Delete batteryastats and fully empty and charge it.

Is it normal for my phone to say "Charged" on the lockscreen but show between 95%-99% on the battery meter? Kinda odd.
My rom is CherryBlur v0.5 btw
CWM, clear battery stats, calibrate battery. Mine sometimes does that. Should still charge to 100% if left.

One of the strangest charging profile I've seen.
That is weird. Miscalibrated battery, maybe? Try a full discharge, then recharge.

I'd never recommend a full discharge for an li-ion battery

It's not recommended to do often, but discharging has been known to solve issues with improper calibration.
Besides, you can't tell me you've never used your shiny Nexus 4 to 0% before ;P

Did you restart your phone while it was charging? I've seen strange dips and spikes in the battery graph on my Nexus S when rebooting while its charging. I haven't seen anything like your graph on my N4 yet but I don't check the graph much plus I've only had the phone about a week and a half.
Hi,
I'm not sure if this has to do with a battery calibration issue, but my Nexus 4 has been charging only up to 75%.
Also, every time I plug in my charger, the battery history used to reset to 0 min. Now, the battery history has been on for 3 days without resetting. I'm guessing this is because the charge doesn't go all the way up to 100%. How do I fix this? I am on stock 4.2.2 and using the stock charger. Should I try using my Nexus 7 charger?
Thanks,
Nexusowner
Use different charger! Stock charger sucks! I had the same problem...

Let it drain all the way, until it shuts itself off. Plug it in and do not turn it on, let it charge all the way. The screen will display charging progress. If the screen is blank press and quickly release the power button to see the status.

Used my MyTouch 4G slide charger and it charged to 100% with the battery history reset. I must have a defective charger. Hopefully, Google will send me a charger and I won't have to RMA my whole phone...

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.
