Let me preface this by saying I have AppleCare (for another year) and I have head 2 major repairs done on this computer. My Macbook Air seems to have garbage battery life. Sitting in class with just firefox open and brightness at 33%, I go from 100% to 65% in less than an hour. Maybe even as little at 40 minutes or so. I just got to class with a full charge and I have 62% just 30 minutes in. I do have 725 cycles, but my battery health says 93%. My computer is also running hot for some reason. 180 degrees, fan on, memory almost fully used. I only have firefox open. Any advice?
