    I just purchased a 15" mid-2012 MBPr. It's been working wonderfully so far, but I'm concerned about the battery. I've had it for 3 days and when it's "charged," it is listed at 99% battery. This morning, after charging it/letting it sleep all night, the "charged" battery is listed at 97%. Should I be concerned, and if so, what can I do? I'd hate to have to take it in for a battery replacement so soon after I got it.

    I'm letting it run off the battery for now to see if I can recalibrate it. But I'm a bit paranoid, especially since I just got the computer.

    According to the help files on my rMBP

    This was found by typing in the term battery into Spotlight and selecting the help file titled "Monitor your portable computer’s battery"

    even in sleep mode the computer OBVIOUSLY uses a small amount of power to keep it in stanby mode

    Ignore the silly-assed battery readouts. Exactly how much time are getting from a charge? (by your watch).
