or just buy extra batteries? I fully charged mine earlier around 2pm then i used everything from skype, frequent logging on line spend 30 mins playing game, 30 mins of music, too at least 8 photos (uploaded some of them online) .... less than 7 hrs later... battery died (take note that wi fi and/or 3G,3.5G is on the whole time. I like it that way, that's why I have 1 extra battery with me and might consider getting a other one.
