The battery life on Apple’s new 3G iPhone isn’t great, but it beats that of other 3G smartphones we’ve seen. PC World’s Test Center ran it through our standard talk-time battery life test, and found that on average it ran 5 hours and 38 minutes, which we consider to be fair.
That’s a big tumble from the superior performance of the original iPhone, which ran on AT&T’s slower EDGE network and lasted the maximum 10 hours of our test. But the 3G iPhone beat out the rest of the current 3G smartphone pack, most of which fell shy of the 5-hour mark that’s the cutoff between a word score of fair and poor in our performance ratings.
