Got a small problem with my 2013 MBA's battery life. I been using the MBA unplugged for a few weeks now and realized the battery is draining much faster than it should. From a full charge the mba gets around 4-5 hours, not sure of the reason. Before I had it plugged in 95% of the time and the few times I took it off the charge the battery didn't seem to have this problem. The Cycle Count is at 155. Can someone take a look at the battery info and see is there something wrong with it? Anyone ran into this problem before? This is my first MBA, I am planning on selling it to upgrade to a 15in MBPr. But I want to fix this problem before I sell it.
