I had the same problem when I first got my HTC Touch Pro 2. You have to charge it to full then let the batter drain completely until it turns itself off. You need to do this about 3 times, then my battery lasted all day. The best way to do this is throw some music on your phone, set it to repeat and turn down your volume this will kill your phone fast. Or download a movie to your phone and watch it that will also kill your phone fast. I hope this helps
