I bought a 13" MacBook Pro a few weeks ago, and have been noticing that I lose 1% of charge for every hour of sleep. For the most part this isn't terribly noticeable, but when I'll go to work for about 10 hours and come home with the charge 10% less, which is pretty significant. Theres nothing that I'm aware of that could potentially wake the computer up while I'm gone. I also just calibrated the battery, and it's still doing the same thing. Health is at 100%, 13 cycles. Is this a common issue? I couldn't find anything about it while searching and I didn't notice this wth any previous Mac portable I've owned. I'd appreciate any input. Thanks!
