Okay this has got to be the worst battery in the history of cell phones. I FULLY charged the battery before I left for dinner at 7:30pm EST tonight. BARELY used it the entire night but left 3G on and turned location services off. Wrote 1 email maybe 3 SMS messages and a note in the memo pad app. After dinner went to see a movie and just got home. It's not 12:05am EST (4:35 min since it was fully charged) and I got the 20% battery warning. Now I know you're supposed to calibrate it over a few days but I know it won't make THAT big a difference. I didn't even make ONE phone call and the phone can't go 5 hours with 3G active!! Now I know some of you are going to say I'm exaggerating but I made sure to note the exact times bc I wanted to see how long it would last b/c I have been having these battery issues since I got it. I don't know what to do besides turn 3G off which I really don't want to do. I also live in Manhattan which is supposed to have great 3G service so it shouldn't be looking for signal too hard and wasting battery. This is sooo frustrating and disappointing. Is it possible I have a defective battery?
