Hello so I was wondering the best way to achive battery life on the go on a MacBook Pro 4,1 model. I.... 1, Lower the brightness to 50% 2, Turn off blue tooth 3, Depending where Airport is off or on. I was wondering if theres a way to really under clock the graphics or even use onboard vga or something or find another way. With that I get 3Hours. For a Mac with less than 10 cycles wheres the 4.5 - 5 Hour battery?
