iPhone to Deliver up to Eight Hours of Talk Time

When it ships on June 29, iPhone will deliver significantly longer battery life than originally estimated: up to 8 hours of talk time, 6 hours of Internet use, 7 hours of video playback or 24 hours of audio playback. It will also feature up to 250 hours (more than 10 days) of standby time. Apple also announced that it has upgraded the entire top surface of iPhone, including its stunning 3.5-inch display, from plastic to optical-quality glass to achieve a superior level of scratch resistance and optical clarity.
