Ubuntu 12.04 has about 2x shorter battery life than OS X on my MacBook Pro 2010. What are the technical reasons for this? Is it because OS X uses some hidden firmware features? Can Linux somehow emulate OS X power saving behavior?
I just recently installed Ubuntu 12.10 64 bit edition on my Macbook Pro.
I am only getting about 1:47 minutes of battery life fully charged. Keyboard backlit off, screen dimness all the way down. From what I've read it seems to be because there is a integrated and dedicated graphics.
