    First boot up of my 13" MBP showed a 5:15 battery life. After calibrating the battery, I saw 4:02, and then a second later it dropped to 99% and I got 3:37. My brightness was at half, Safari was the only app open, just sitting plainly on Apple.com. Bluetooth was off. Wifi was on. Backlit keyboard was off.

    Now my battery health (iStat Pro) indicates my battery health is at 99%. After a few hours!

    Is something wrong with the MBP or is this just a software glitch after calibrating?

    It was at 100% this morning, and even last night. The battery health was 100% as soon as I got it, as well as this morning. As soon as I unplugged it, it dropped back to 99%. After about charging for 20 minutes, its still at 99% (the health and the charge).

    Well.. As far as I know, the charger won't actually activate till it's lower than 95%. Regardless of what an Apple Genus might say.
