    Seems a little low. You could ask for a replacement and shouldn't have to pay for it.

    What year and model MBP do you have? The built-in batteries in the newer Mac unibody notebooks come pre-calibrated and do not require regular calibration like the removable batteries.

    It is perfectly normal if your battery health (maximum capacity) is less than 100% when new or if it fluctuates up or down over time. If it drops below 80%, take it to Apple so they can check to determine if it's defective. For further details, read the CHECKING STATUS AND HEALTH section of the following link.

    This should answer most, if not all, of your battery questions:

    technically it's still within Apples margins for battery health (above 80% for 1000 cycles), but I understand that this is not a satisfactory state.

    If you have AppleCare, they should be flexible enough to replace the battery for you. If you don't, you can still try, but most likely they will offer you to replace the battery for the regular price only.

    As I posted earlier, and as is stated in the Battery FAQ, it's normal that your battery health fluctuates up and down over time. I suggest you forget about it, and just relax and enjoy your Mac.

    Maybe you should start a blog... or at least a twitter account, for hourly updates of your battery status.

    mine is at 103.2% right now :p

    By far this is the best reply to any of the "OMG my battery is at 95% capacity posts". You sir are my hero.

    I got my battery replaced when at 250 cycles because it was at 89% health even after calibrating. The genius bar deemed it would hit 80% before the promised 1000 cycles. On the new battery (about 16 months after they replaced it), I'm at 314 cycles and 90% health. I'll be going back if it drops below 88% before 500 cycles.

    i have read a similar problem somewhere else.... where the users battery is deteriorating due to the magsafe charger plugged in all the time into their macbook. see if you can use the macbook pro w/o the magsafe plugged in to your macbook pro for a couple of days and see if the batterys health will improve.

    oh, and do post the results on here as well.
