    Is there anything that needs to be done initially with the iPhone 4 to ensure proper battery calibration and health?

    Charge it to 100%, let it drain until it shuts itself off, recharge to 100% and keep connected to charger for an hour or so afterward. Battery is now calibrated.

    Just like any battery. Fully charge it, dully drain it (almost)

    Awesome. Thanks a lot!
    Phone is at 12% now.. I'll just let it die before I plug it in.

    Impressively, that is with:
    8 hours and 43 minutes of usage
    23 hours 33 minutes of standby

    Battery lasts quite a bit longer than the 3GS..
