    Battery "sleep" power consumption rate?
    Hi there

    Macbook. 18 months old
    how much battery should I expect to see next morning if I put my Macbook to sleep with 100%?
    It seems to be about 80%. Could have sworn my old Mac notebook did better than that.....is it OK?

    thanx

    Actual battery usage is going to depend upon what the total capacity of your battery is. As batteries get older then hold less and less charge. So 80% on your 18 month old laptop is not that bad. I know I usually have to replace the battery on most Dell's and Lenovo's after 12-18 months.
