We test talk time by setting up a call to the phone (with voices speaking at both ends) and timing how long the call lasts before the phone hangs up. The iPhone has a pretty good sized battery in there (according to iFixit, who took one apart (http://stream.ifixit.com/)), but the battery life of the iPhone making calls wasn't great; we measured it at 4 hours and 3 minutes in our first test and 5 hours and 1 minute in our second; we are running more tests now, and won't assign the iPhone a score until we have completed these tests. That's comparable with the Helio Ocean, but is significantly shorter than the LG Prada and the N95. And it's less than half that of the BlackBerry 8800, which lasted over 10 hours.
