I recently bought a new Unibody MBP, the 2.53 GHz variant with a 7.200 rpm HDD. As I also have a white MacBook (Spring 2008), I am really confused about the MBP's short battery life, be it either with the 9400 or the 9600 graphics adapter. I only get about 2.2 hours while I just surf (be it the 9400 or 9600). The white MB gives up to 5 hours. Also the battery's capacity loses 2-4% per hour in sleep mode while not attached to the power adapter. So I would like to know, how many minutes you get with you MPBs. Sorry for the double post. Can my (now) two threads be somehow merged, with the poll included?
