After using Spirit on my 3.1.3 iPod and installing Winterboard, a wallpaper and some more for Winterboard, and Categories, I feel like my battery is going down somewhat faster, maybe it's not, but it just feels like I'm having less time to do stuff on my iPod. I have wifi etc. off, is the jailbreaking the problem? i suppose it isn't worth busting my battery for jailbreaking. Is it winterboard? is it categories? or is it spirit that's doing it?
