The wireless web browsing test uses the 802.11n connection to browse a series of 20 web pages varying in size, spending 20 seconds on each page (I timed how long it takes me to read a page on Digg and came up with 36 seconds; I standardized on 20 seconds for the test to make things a little more stressful). The test continues to loop all while playing MP3s in iTunes.

And with screen at half brightness (I always set it to the lowest while traveling, which is not very usable especially during the daytime):

The new 15-inch MacBook Pro lasted eight hours and eight minutes.

Well it IS the best best battery life I’ve ever seen also. Mine could only last for around 2 hours now. And yes it is non-changeable and is fixed in the machine but I think that’s fine (for me at least). I’m not carrying a extra battery with my Macbook Pro even when it’s changeable, so why would the non-changeable battery bother me anyway?

Here’s a chart from AnandTech:

The test result is quite amazing. Good job, Apple!
