Just bought a new late 2013 macbook pro retina. Everything is sweet, but the battery seems a little off. First i charged it to 100 percent then it said 20:00 hours left, then it dropped to 13, then 11, then settled at 9, then said calculating for a little while. I downloaded coconut, it shows correct battery discharge and everything is good. It seems mavericks drops the battery percentage about 5 percent slower than the actual. Ive left it on, with the screen on all day to just see if it would stablize. It seems to have but is anyone else having this issue? Is there anything i can do? Ive already clean installed mavericks.
thanks
