here's my question about the test with the Envy 17, did they do all the same optimizations inside Windows 7 that don't come set out of the box, but are in OSX as well and configured for longer battery life? Everyone knows Apple laptops cannot use more than 25% of their CPU power while in battery mode, there's also tons of other settings that are configurable as well including turning down the wifi antennas power. We were able to squeeze just over another hour of battery life out of my roommates laptop playing with the settings.
Patently false.
My roommate just ran 4 tests on his Late 08 MBP (early unibody, removeable battery). He ran CineBench (a cross platform benchmarking tool)
He scored the following CPU scores;
Plugged, battery in: 1.32
Plugged, battery out: 1.32
Unplugged, battery in: 1.32
Unplugged, battery out: 0 (obviously )
So, that puts the 25% power (or even reduced power) theory to bed when on battery or plugged in without battery.
