Snow Leopard Unibody MBP Battery Life Test #5 : The Apple Test 2

It turns out that I need a lot of time just to complete the Mac Book Pro battery test. Well, I have completed item #5 in my checklist, which is to repeat the battery test as close enough to the way Apple tested them after a clean install of Snow Leopard.

As with item #2 I did a partial using Apple scenario, only this time I did not start from 100%. I take notes of the battery usage while I was browsing quite heavily searching for the best computer spec for my brother in law. The only applications running were Firefox and TextEdit. We were in a relatively dark room and I constantly adjusted the brightness to be at 50%.

The result : my battery is down 29% in 97 minutes. The average battery usage is 0.2989% per minute, which means 100% battery life would approximately equal to 334 minutes or 5 hours and 34 minutes of usage.

That is not so bad, considering that I was browsing heavily that day, the fans even turned on, something that I do not experience much.
