Snow Leopard Unibody MBP Battery Life Test #4 : Real-World Usage 2

For the last test, since daily usage would vary from day to day, I did 3 runs, so that the result would better represent the case.

1st Run

What I did : Edited Google Wave documents, worked with some flash documents, listened to music and the occasional chat.
Running programs : Firefox, iTunes, Adium, TextEdit
Environment : Worked at a bright location, so screen should be at 100% most of the time
The result : Battery is down 53% in 149 minutes, average battery usage is 0.355704 % per minute, 100% battery would approximately equal to 4 hours and 41 minutes.

2nd Run

What I did : Web-based administration, server administration (using SSH), email, and a bit of coding in Windows through Remote Desktop Connection
Running programs : Firefox, Mail, Adium, TextEdit, Activity Monitor, Terminal (SSH), Remote Desktop Connection, Google Chrome
Environment : Worked at a relatively bright room, screen is probably about 70% to 100%
The result : Battery is down 60% in 134 minutes, average battery usage is 0.4477612 % per minute, 100% battery would approximately equal to 3 hours and 43 minutes.

3rd Run

What I did : Web-based administration, browsing some websites, email, encoded two 20-minutes long videos using HandBrake, internet connection using bluetooth
Running programs : Firefox, Mail, Handbrake, TextEdit, OpenOffice.org
Environment : Room wasn’t so bright, screen is probably about 70% to 80%
The result : Battery is down 65% in 119 minutes, average battery usage is 0.5462185 % per minute, 100% battery would approximately equal to 3 hours and 3 minutes.

Ok, since all of the tests have been completed, next I will try to write a conclusion from my tests.
