Greetings all, I can only use my Droid 2 with the original battery for about 4 hours. Granted I'm doing a lot with it, but that is hardly a half a day on a charge. (And I'm not going to use the "task killers" that I've been warned about using.) So I purchased an extended batter (2800mha) and I get just about the exact same battery life as with the original battery. Can anyone tell me if there is a battery that truly extends the life of the phone on a single charge? Thank you.
