    The battery time on my Macbook Pro 15" goes from one time to another in a matter of minutes. I fully charged the battery after it had been drained. This is what I mean by fluctuating:

    11:23am-11:28am (5m)
    7h51m, 5h54m, 6h57m, 6h16m, 5h29m, 6h38m, 5h53m, 6h29m, 6h9m, 6h13m

    11:29-11:34 (5m)
    6h39m, 6h36m, 6h4m, 6h8m, 6h49m, 5h52m, 6h30m, 6h0m, 5h43m, 6h30m

    Apple states that it should get 8-9 hours on a full charge and mine gets 6h15m. It's only 10mos old.

    Any ideas would be greatly appreciated. :)

    Fluctuation is normal, as the time indicator takes into account your usage, and the CPU use is almost never constant.
