“By now you’ve heard that under ‘normal’ usage, the Air can only manage about 2.5 hours of battery life. That’s true and at the same time it isn’t. I touch on part of this in the review, but the MacBook Air isn’t designed to be your work notebook – no ultra portable is. It’s a notebook for a writer, for someone taking notes in class; it’s a second notebook, or a third system. As such, the typical usage model can be very different than your standard notebook,” Anand Lal Shimpi reports for AnandTech.
“At the same time, most of the people considering the Air aren’t looking at it as a second notebook or a third system, they are looking at it as their primary notebook (and will be left sorely disappointed or frustrated after a while). The end result is that you need a handful of battery life tests to really cover all bases. And that’s what I’ve done,” Lal Shimpi reports.
Lal Shimpi’s tests revealed:
• 4.27 hours for wireless Internet browsing and MP3 playback
• 3.42 hours for DVD playback
• 2.43 hours for Xvid playback, Web browsing, and heavy downloading
