I would try a full wipe if the problem can't be identified... Generally speaking if you start with a fresh OS and still have the issue it could be something more serious
I purchased a Nexus 7 on 10/20/12.........and in the last three days it has yet to hold a charge for anything near a day. Last night I took it off the charger, fully charged, @ 9:00 P.M.
Arose this A.M. at 5:00.......did nothing from one time to the next other than read some e-mail. The battery is less than half charged !! Useless digital toy if this is characteristic. Will find out @ dealer today....I assume they'll tell me that too many apps are running in the background, GPS is on too much, etc. Hopefully, there will be a higher quality response.
Switch 3G tablets to airplane mode and see how standby time improvedWe have 4 nexus 7s in our family 2 are 32g wifi 2 are 32gig 3g. the two32wifi will last up to 9 days in sleep mode even with wifi left on. one of the 3G will last for 4-5 days in sleep mode. All 4 tablets run 4.2.2 Mine will last 8 hours in sleep mode and drains between 5 and 10 percent per hour. Again seems to have started after 4.2.2 upgrade. After 30 factory resets and trying almost every solution and suggested app I still have the problem. if I power it off it will not drain the battery so I think we can rule out a faulty battery. It would be good roll back to 4.1.2 but not a simple procedure. I think the next step will be a return to manufacturer. The 3 G that is now working fine was replaced due to the battery only charging when switched off problem.
Did it go to deep sleep? You still need to find the culprit app.I'm having battery problems too. When I first got my nexus the battery didn't drain,my battery started draining a lot a couple days ago. At first I thought it was a game I installed but now I'm thinking it the tablet update. After I updated it it started draining battery. Maybe only some people got effected by the update? A similar thing happend to my phone I replaced the battery and it was fixed but u can't replace the battery on your tablet so I am wondering how to fix the problem too.
