    I have owned a black MacBook for a little under a year now and I have always had a "problem" where the battery drains quite fast while it's sleeping. I have owned 2 powerbook's and an ibook and they never used so much battery while sleeping.

    Before i went to bed the battery level was at 62% and when i woke it up 12 or so hours later is was at 53%.

    Like i've said, the past apple laptops i've had have not been like this. Does anyone else experience battery drain to this extent?

    My White macbook does the same, around 10% overnight. A colleague of mine has a 12" Powerbook, and his sleep drain is somewhat similar, but that machine is 3 years old.

    Maybe OT:

    What bothers me is, if I turn it off with a full charge (100%) next day it will turn on at 99%, and next day at 98% till the 5th day it will start charging because the charge dropped under 95%.
    But I noticed that my PC notebook has exactly the same behaviour.

    Note: I noticed recently (PC notebook) that after some time of use, and fully charged and plugged, suddenly starts charging again. I think that the wall socket somehow doesn't have current all the time. So I'd have to check the installation.
