ok, so i got my captivate on July 30th. i think its totally died like 3 or 4 times now but it still seems to die very quickly. i have the adv app killer on there, i turn off bluetooth when not in use, brightness is as low as it will go, no haptic feedback, gps off and yet i still know that by the time i get home unless i charge it in the car, i won't be able to use my phone after work. so, i'd like your guys thoughts on whether it would be worth it to take back to the at&t store and swap it out for a new one? thanks for your thoughts!
