So far my iphone 3G 16gb after a full chrage gave me just over 3 hours usage which is consider to be awful. Lots of other users have also been having simmilar problems. Form what I have been reading it looks like everyone is having this issue In which case I'm going to ask for a refund. I just want assurance that there are some people out there that are getting a decent 5-7 hours usage out of their phones. Also if I take my iphone into a apple store in the Uk could they fix the battery or replace it for me ?
