Nexus 10 super battery drain.

[Adam MacRae]

I woke up in the morning and unplugged the N10 from the charger, did some light browsing, then put the tablet on standby and went to work. When I got home from work, my girlfriend asked me why she couldn't turn on the N10. I tried to turn it on once, nothing, a second time, and it started to boot up. When I left for work my battery was around 80% but when I booted it up after coming home the battery had drained hugely, and it booted up at only around 40% battery.

Is this a bug in 4.2.1? I sometimes have this rebooting issue with my N4, but I've never noticed the battery drain like I did with the N10.

Android just updated to 4.2.2 last night. Turn the Tablet off and charge it to 100% When you turn it back on. Go into settings, about tablet, system updates. Update it and see if it fixes the problem. Also Android Malware has been on the raise with Android so I suggest going into google play and downloading a free antivirus. I got norton mobile security free.

Updating is a good idea but those free anti-virus apps are a waste of time and space, they're useless.

My guess is your tablet might have crashed while you were at work (a common occurrence on many units it seems which the new update is said to have fixed) and rebooting it usually drains the battery quite a bit. I haven't had that problem though so I wouldn't know for sure if this is true but it is true when my 3VO does the same thing.

I had this problem early on. I would play NFS and after exiting the battery level would be constant. If I rebooted, it would show a dramatic drop like the screen shot above. As time went on it was totally unreliable, the battery almost never show a drain, I had to reboot to get a real-time reading, very annoying. I didn't have to play NFS, just normal usage would show no drain. I also started getting, very regularly, restarts every time I plugged and unplugged power. That has gone away with 4.2.2 so far.

I guess that's been another issue noted by Google and fixed. (Y)

He should just wait for the 4.2.2 update...

Shouldn't be long.

A couple times on my phone it got stuck downloading something. Twice it was when I was re-syncing my Exchange account via Touchdown, then once or twice it was just an app store download... but what it did was just suck down data! Back of the phone was hot from all the activity, and battery dropped like 20% in 15 minutes. I've never seen it happen on my N10, but this could have been a random fluke like that. I always say things are not a problem unless they happen more than once. (In general you know, not literally everything!) But yes - everything is moot if we are not talking about 4.2.2 "Bug Crusher!"
