Well, just turn off the 3G and don't have your phone push e-mail so much.

No problem with my Centro lasting through the day with 3G and push e-mail and even got a standard size extended battery with about 200 mAh more juice than OEM battery. But, hey, when the battery runs low, I just pop out one battery and put in the spare. No biggie.

iPhone is a really cool multimedia/web browsing phone, but wished they made the battery removable.
