I have had my Nexus 7 (16gig) for a week now, bought it at a local Sam's. Overall I love it. My one complaint is a big one:


The battery seems to drain as fast when the tablet is put to sleep and when it is in use with the screen at 100% !

I powered up the Nexus 7 at about 11am this morning and the battery was at 100% after a full nights charge. I used it to read for about an hour then shut the screen down. It was undisturbed until it about 10:30pm and the battery was completely dead would not even display the charging icon, let alone boot up for about 5 minutes after put on the charger?

Do I have a defective unit or is something not set right? It is still stock 4.1.1.

My Kindle Fire had amazing battery life when in sleep mode, like more than 24 hours.

either defective or an app chewing it up.

My battery life is brilliant. I charged it up on Sat afternoon, took it off charger at 5pm. Didn't touch it again until 11am on Sunday morning -- 18 hours sleep -- and came back to it with 93% battery, This sleeps well, unlike my Xperia S

The only complaint I have about he nexus is also battery life, although nowhere nears as bad as the op, it's not even close to the iPad, which I can leave on standby for a week and come back to with plenty of life left, i'm lucky to get 3 days of standby on the nexus.

a lot depends on what you have syncing in the background and what settings you have. I don't use social media accounts much at all and as a result am not logged into them or syncing them. When I shut off the screen I have very little battery drain at all.

Sounds like an app or something is keeping the system awake. Check battery use settings. Has lots of useful information like keep awake time for different apps and stuff. Not perfect but gives an Idea.

I like to use the app "Batterysnap" so I get real time tracking for battery level, voltage, temp etc and I can view it in a nice graph.

Might want check out Google wallet, sounds dumb i know. My battery seemed to drain more in sleep one day, went into Google wallet (this was an issue on the nexus s early on). Even though i had already set it up the app acted like it was never opened, and would sit there trying setup for first time use and would hang at loading the tos.

Might be in my head, but the device drains at a respectable rate now

I had the same issue on my HTC HD2 running android, turned out it was an app that was running in the background keeping the GPS radio on and searching for a sat lock, disabled it and fixed the issue!

just check your battery stats and see what's keeping the CPU churning.
