i've also found that you check the programs that you download from market as many have ads in them, and will constantly be pulling data using internet connection to show those ads. The less of those running the better too. I only have my battery able to run about 14-16 hours, and only about 5-6 if I'm using it a fair amount during the day. My task manager I have shuts off all non-exluded programs when the screen is off, so it will still be pretty full at the end of the day if I don't use it.
