Battery issues!

I recently have been having battery issues with my IPT. When I have it charged fully and leave it in sleep mode over night, it will drain all the way down to about 10% (in just about 8 hrs). Does anyone know why it is doing this?

I always leave it in sleep mode and it has never done this before, but for the past 3-4 nights, it has.

The IPT has installer.app on it. It has iPhone apps, NES, Tetromino, iSolitaire, iBlackJack, Mines, Sudoku, TTR, iFlix, iPhysics, SMBPrefs, Installer, and Customize.

I have my mail set to check every hour and I've never had battery issues doing that. The last thing I installed before having these problems was the Blaze repo pack. I uninstalled it yesterday to see if that would do anything, but still nothing.

One thing I did leave was iPhysics. Maybe that could be the problem?

 

Aight, I just did it. I'll let you guys know if that fixed the problem. In the mean time, does anyone else have other suggestions? The more the better, right?
