I know I've read about this here, but haven't been able to find it. My 3 week old 11" maxed out MBA lost 29% battery. From 100 to 71% in 24 hours with the clamshell closed. I remember reading it should drop 2 or 3 %, not 30 I have added Chrome and a weather program but not much else. I thought the battery was draining fast during use so I charged it up, closed it and did not touch for 24 hours. Is Google doing this to me? Obviously I am new to the world of Apple notebooks and in my learning curve.
