Hey all I just got my first Iphone (3gs 32gb) and am new to the forums. I have been reading a ton of threads about battery questions and problems and they have all been pretty extreme i.e. having 10 hour standby usage. Well I don't have that much of a problem but I was wondering if anyone could tell me if its just me or I should exchange my Iphone. I am sitting at 27% battery life after 3 hrs 48 min usage and 7 hrs 32 min standby. I have wifi and push off but i do have 3g on and my screen brightness is only a little over half way. 95% of the usage has been text messages with a little 3-4 minute video. It just doesnt seem right my sisters 3g can go all day with 40% or more battery life left and I am having to charge once-twice a day. Any help would be appreciated.
