i know there is already a thread about the 3g iphone's poor battery performance, but here i'd like to know if other 3g iphone owners would actually consider exchanging their iphones due to such bad battery performance? i mean this morning my iphone was fully charged. it's now 11:30am, i'll i've done is play around 10 minutes of dizzy bee game and maybe listen to 10 minutes of cold play on the speaker and the battery indicator is already down to half and i haven't even made or received any calls! i have 3g and location services off. surely this can't be right, i haven't even got through half the day yet. could some batteries perform worse than others?
