[Edwood]

My home is on the fringe of EVDO, so it constantly hunts for a signal with all my other Sprint Pocket PC's. There is very quick battery drain.

Either way, my TP2 lasts the entire day with power to spare. Whether or not it's because the TP2 has a better radio or management of EVDO is up for debate. But I'm guessing the larger stock battery capacity might have something to do with it's better battery life too.
