I really don't understand how everybody manages to kill the battery in a few hours. Sure, it is very doable if you keep the phone active all the time, but after tweaking a few settings and managing things like BT, GPS and updates, and using WiFi whenever possible, I've found that my phone easily lasts through a day and then some. Like I said before, excessive data traffic, gaming and use of the GPS are the three things that'll kill your battery in no time. These phones aren't really designed as a laptop substitute; they're simply a more advanced way of staying in touch and getting stuff done while on the go.
