Right well i got my iphone 4 on Monday and i charged it up for 24.5 hours like it says in the manual, however i seem to be able to go from 100% to 79% battery in 15 minutes with nothing but music playing, now if i even try to use my A2DP headset its like flood gates open and it goes from 100-23% in the same amount of time at most i get maybe 45 minutes of use out of the phone ive taken it to apple and they said theres nothing wrong but there obviously is something seriously wrong with it. any help would be appreciated.
