I recently bought a refurb pearl on at&t around two weeks ago and it works great. But I realize when I leave JiveTalk running and use my phone for very light browsering my battery drains so fast. It goes from like 100 to 20 in 3 - 5 hours.. I'm wondering if it is a battery or is it normal since I see people talking about their pearls going for a day straight with jivetalk..

I have nothing else in the background running either and have 30 megs free of space..
