Those pranksters at PC Mag have come up with a completely scientific methodology that predicts when your iPhone will bite the dust. Cuz, you know, you can’t replace the battery on your own. The iPhone is slated to hold 80 percent of a charge after 400 charges, but I think the foul weather has caused our friends to eat some mushrooms and they’re boosting that number to 450 cycles. They’ve also estimated that you’ll be charging your iPhone every 34 hours, so the math becomes very simple, 450 charges x 1.5 days = 675 days. Chances are you’ll be upgrading to 2G by then.
