I read a little thread a few weeks ago on how to improve battery life. I've used the trick mentioned in that really works. 1 - Drain your phone battery 2 - Charge your phone to full until the light becomes green 3 - Unplug your phone. 4 - Power off your phone. 5 - Charge your while it's powered off 6- When the little light becomes green. You are done. This works for most HTC Phones.
