It's me again! Decided to open a new thread about this, as there might be others wondering the same thing. How long can the battery of 2012 11" i5 MBA last if the AirPort and Bluetooth are turned off, brightness of the screen is <50% and only a text editor and a browser (without Flash or any kind of video playback) is open? I think this way it might be possible to get 7 hours of battery life instead of 5 hours. Am I right? Thanks in advance!
