    I have been using my new mbp for a few days now and would like some info on the battery. The guides seem a bit vague in places, and the apple staff can't seem to give me a straight answer.

    Firstly, I have calibrated my battery but the icon and istat pro still state that 99% is fully charged. Is there a problem with my computer or should I just ignore that?

    Secondly, what % is a good time to recharge the battery? I have heard some rumours that when the battery drops to 20% I should recharge. Is this correct or doesn't it matter at all?

    Thirdly and Finally, is using the laptop at full charge with the charger plugged in bad for the battery in the long term?


    Any advice would be great!
