The battery life of cell phones just doesn’t seem to be as long as it used to be. If your Android device is dying faster than you would like, Wakelock Detector can help you to home in on apps you have installed that might be killing your battery or preventing the screen from switching off.

This is something that I'm personally very interested in... I have a Nexus 7 tablet, and after it upgraded to Android version 4.2.1, the battery life was just awful. After 4.2.2, the battery life would just randomly decide to go from 100% down to 10% over a couple of hours while sitting on the table, unused.
The problem, after doing a lot of research, was a wakelock that something was holding. After a ton of app upgrades, the problem mostly went away. But even now, I'll occasionally come back to the tablet and half the battery has drained in just a couple of hours.
Definitely going to try this app and see if I can track down the problem.

Check your wifi settings and see if your "Keep Wi-Fi on during sleep" is set to anything other than "Always". I experienced the same thing with the other two options, where my Nexus 7 would drain extremely fast.
