Adobe Flash uses 30% of the MacBook Air's Battery Life

There are a lot of factors when it comes to batter life — heat, current processes, screen brightness, WiFi and Bluetooth (among other things), and the MacBook Air managed to run completely fine using everything you’d need — but when Flash was started up, battery life dropped from 6 hours to 4 hours.
