hmm I'm surprised at most of you being impressed with the battery life... the first two days I used it I couldn't get it to go through a full work shift with normal-light to heavy usage. I think it was getting around 6 hours off a full charge, and then the next day I tried to test it and turned on everything, wifi, bluetooth, gps... and it still seemed bad 5 to 6ish hours, but I mean that's understandable, I can live with that.
however I did find a big topic about how the default sms keeps the phone from sleeping when you send a text message. and it keeps the cpu at 100% even when the screen isn't on, and so they suggest disabling the default text and downloading HandCent sms... so I did, and wow couldn't believe it, I charged my phone to 100% by 2 oclock in the afternoon and by 8am the next morning I was only down to 40% battery life. (I had been playing alot of games on the phone too)

and I was thanking God... but then the terrible happened.
I was using it about 9 oclock this morning and all the sudden it cut off on me and turned back on... and the battery life went from 40% to 15%?? wtf? so that kind of flustered me. I'm gonna give it another few days, otherwise I'm taking this back and they better give me a new one. cause something aint right about that.
I love the phone though seriously, my whole post was just about the shady battery, I don't want to switch phones I just want them fixed, cause the user community/ free downloads/UI/Performance are amazing.
