Seems At&t iphone 4 has a poor battery life since updating to the 4.3, many iphone 4 owners are complaining about a poor battery life since the update. I'm happy to report my Verizon iphone 4 has a better battery life than my HTC Incredible. The Verizon iPhone updated is 4.2.6 which is equivalent to the 4.3 version. . . .
