MacBook Air battery life

The MacBook Air's touted five-hour battery life is an almost acceptable measure of the ultraportable's abilities, while enthusiast site Mac on Air has performed a full take-apart of the laptop. According to tests performed by AnandTech, the MacBook Air is capable of running for four and a quarter hours with normal web browsing, while playing MP3s in the background. The test was conducted by browsing 20 web pages, spending 20 seconds per page, and looping music in the background. This test was designed to emulate standard usage, as one would experience taking notes in class or using the Air during their daily commute.

Looping a video file from the hard drive lessened the life of the Air to three and a half hours, while a heavy downloading and multitasking test lowered the results by an additional hour.

The tester concludes that the battery life will not suit most power users, but would do nicely for those who commute or require a machine for note-taking and internet.
