Battery life is one of the things I utterly hate about my Iphone. I used to get days of use out of my old "dumb" phones before needing to recharge them. By comparison, my Iphone needs to be recharged every single day, even on days when I only use the phone to make and recieve calls. When I first got it I actually thought there had to be something wrong with it!

After a while I got used to the poor battery life (and started carrying a charger everywhere), but I would trade some of that sleek thin design for a longer lasting battery in a heartbeat. My brother has one of the Motorola Droid phones and he easily gets a weekend out of his phone under similar usage conditions.
