    Hey guys,

    I've recently received my Santa Rosa Macbook Pro replacement and I noticed that the charge remaining on my battery is 5403 mAh. This is after 4 cycles and one of them was a full battery re-calibration.

    My first Macbook Pro had a charge remaining of roughly 6000 and that was still after 20 cycles or so. However, this replacement has a larger 200GB 7200 RPM hard drive.

    Is the hard drive sucking up the battery life? Or is there something wrong with the battery? Can I get Apple to replace it?

    Any help would be appreciated.

    Cheers,

    The 17inch starts around 6200mAh, and the 15inch starts around 5500mAh. should stay above 80% within 300 cycles. Hope this helps

    There's no need to recalibrate that often. Apple says every 1-2 months, and lots of people don't recalibrate at all. Doing it after 4 cycles seems a bit much.

    Think yourself lucky... my MacBook Pro's battery has done 5 cycles and the full charge capacity is only 370 mAh. :eek: :rolleyes:

    Yup... time to call Apple for a free replacement battery. :)

    Had about the same problem but my capacity went down to -1 mAh after about 3 months.

    Went in to Apple few days ago and got a free replacement.

    Make an appointment with the Genius Bar.

    does it cost money to go to the genius bar? Does your mac have to be under warranty?
