hey guys i just got out of the stone age with my old phone and upgraded to the thunderbolt. I was in the middle of getting the iphone and did alot of research and came up with the thunderbolt is so much better in alot of ways. Here are some problems i am having the battery life is not that good so far within 4 hours of not using my phone it was completely charged it was down to 10% battery life. Since i am new with the phone i didnt know you had to close all the apps out. Also today i am trying to see how long i can go with the 4G turned off with the form i read on here. is there anything else that can help besides buying the big battery that makes the phone look bulky.
