    Do a hard reset and try again.

    Calibrate the battery by letting it run until it turns off, then recharge.

    The battery does not need calibrating. The battery stat file may though.

    You let the battery run out (until the phone shuts off for lack of juice), then recharge. Semantics as you are not actually calibrating the battery per se, but the file that determines how charged the battery is.
