"[3G] chipsets work well apart from power. They're real power hogs. Most phones now have battery lives of 2 to 3 hours and that's due to these very power-hungry 3G chipsets," he explained. "[iPhone] has 8 hours of talktime life. That's really important when you start to use the Internet and want to use the phone to listen to music. We've got to see the battery lives for 3G get back up into the 5+ hour range. Hopefully we'll see that late next year."
my comment:
I tend to believe Steve Jobs this time. Perhaps I shouldn't but I do. He knows the market for the iPhone better than anybody else.
