Colbyy, you got nearly three hours of screen on time from a 1650 mAh battery. Personally, I would say that is pretty amazing. Granted, it looks bad because it only got 10 hours on it, but that is pretty heavy usage. I don't think there is much to be done to improve life with that kind of use.
The Commandments of Android
1) Open RAM is wasted RAM - Don't use Task Killers
2) Cheap devices are cheap for a reason. Don't expect high end performance.
3) Boot Loop = Wipe.
4) There are no viruses for android.
