    I just bought my Macbook Pro a couple of hours ago. I know the Back to School event starts tomorrow, but the guy at the Apple store said that if it starts within a month they'll give me the gift card without returning anything.

    The battery is at 6 hours on 100% battery and steadily dropped from 100% to 97%, it said 5:24, in like two minutes. Is this normal?

    I have the brightness up and have flash enabled I think, so could that be the reason for not getting the supposed 7 hours?

    Thank You!

    Yes it's normal.

    Stop worrying about little percentage changes, and just enjoy your shiny new Mac.:)

    Congrats on the purchase.

    100% normal. The system constantly recalculates the estimated battery time based on your usage. Thus, it isn't uncommon for the battery time to jump around, sometimes by as much as an hour or two. As noted, read the Battery FAQ posted above^^^ and you'll be fine :)

    Yep, be true for all laptops and not just macbooks. Thrashing your CPU and battery remaining will show say 1 hour left, stop your task and the battery will suddenly say 3 hours remaining though the percentage will be the same.

    If it's brand new, it'll take a few charge/discharge cycles for the battery to get it's full capacity.

    Thank you for all of the responses. I got one of the apps suggested in the link, I think it was iStat, and it says the health is at 97% with 0 cycles. That is normal as well I am guessing/hoping?
