If you have a lot of apps open, tap the Recent Apps button and remove all the apps.

Reboot your tablet: Many users have reported that a simple reboot has fixed the battery drain problem. What you have to do is to turn off your Nexus 7 and leave it off for a few minutes and then turn it on. This will let the battery rest and help it to work properly.
