Sorry if this is a silly question, I used the search, but could not find what I was looking for.

Basically, my friends 17" MBP get's about 7 hours of battery life with a brighter screen and more use then when my 15" MBP get's maybe 3 hours with half the brightness and usage than his. I decided to have the battery replaced on my book, thinking it was that, I took it to the genius bar and was replaced under warranty, but it's still the same situation even after I calibrated the battery. So the only thing I can think of is he has a bigger battery, but I can't remove his battery because it's just a flush bottom, unlike where I can just click the flap that releases my battery. He has I believe the same year MBP...

Any ideas?

Thanks in advance! Tim
