I just got my MBA today and want to do a calibration early on so that my battery lasts longer in the long term, so I googled around and found a youtube video that showed a terminal command that ramps up the processor core's, yes, both cores, to 100%, quickly draining the battery, but even still, it takes forever lol. I've got 5 tabs open at the moment in google chrome all playing a 12-minute gameplay trailer for battlefield 3 in 1080P with every single program that is loaded on my MBA running in the background, and browsing the web. My battery meter says it has 1:21 left till it dies, and my fans are a 6452 RPM. So, do you guys know any other hints that helps battery calibration that much less painful? Thanks in advance. Also, here's the link to the youtube video that shows the terminal commands that will ramp up the processor cores to 100% quickly.
