    turn off all your screen savers and energy settings and let it run full blast once a month before bedtime....

    get up and plug it in -

    done....

    Speaking of this, my battery indicator is NEVER accurate, I've had it for about 4 days now and I've let it go all the way down twice and let it sit. It might say 52% with 2:10 remaining and then a minute later say 3:40 remaining, it's all over the place all the time. I have the 11"...

    Anyone??

    That's because it calculates based on what you're doing. This is not a "real world" estimate. You can browse and such for probably 5+ hours. But don't expect to stream movies for 5 hours.

    No longer needed ever? I know there's no need to calibrate when you first pull it new out of the box, but I didn't think it meant it didn't need calibrating ever. Is this true?

    Honestly, what do you gain after calibrating the battery, other than a "more pleasing" display in the battery info?

    So for the fact these calibrating stuff does not "change" the battery at all, what's the point of doing so?

    And yes, Apple says newer models don't need to be calibrated.
