如果用 Mountain Lion，快D update 去 10.8.2 啦，會顯著解決過熱及明顯加長電池壽命
The following observations are anecdotal and not scientific by any means, but findings thus far with OS X 10.8.2 include:
Dramatic improvements to battery life on three different MacBook Airs (2010, 2011, and 2012 models), each jumping by at least 2 hours to an average of 6 hours under normal use
Portable Macs running OS X 10.8.2 appear to run at lower temperatures and are noticeably cooler to the touch, perhaps suggesting the original battery life issue was related to power management or an errant background process
The largest boost was found on a 2011 MacBook Air 11″ model, which jumped from 3.4 hours to 6 hours on a full charge. This was shown by the Battery Time Remaining app and proved accurate while running a clock to observe battery drain under standard usage conditions at 70% display brightness.
