Just wondering, but for some reason the battery life on my iPhone does not seem to come close to the advertised life. I got my phone two days ago and after a full nights charge the first day I was down to half the battery life by midday the next after light-moderate use. My question is do you think I could get apple to replace it with a new one? and if so what is the best way to go about doing so? Call the apple store I bought it from?
