Tomorrow i will be going to an apple store to try to get my black 16gb iphone replaced because its battery life is becoming just unacceptable. i got it day one and since then its been performing okay, but now I'm getting 1 1/2 - 2 1/2 hours of battery life from listening to music for about 2 1/2 hours, and a total of about half an hour of Internet on WiFi, and the occasional phone call. and some days i hardly do anything and by the end of the day i have a half to a quarter of battery left. I just wanted to know when i get my exchange if i can request for a white iphone? or does my exchange have to be the same exact model? Pic: an example of how bad my battery is.
