That will depend on what you're doing while on the battery - but I would expect it to last longer than that. Can you describe your usage while experiencing the 2.5hr battery life?

This is a very very very high demand activity. Why the heck are you doing this on battery power anyway...why don't you have your MacBook Pro plugged in?

Doing this sort of activity on battery power is like driving your car with the pedal to the floor. If you did that with a car...you would get very very poor gas mileage. You're basically doing the same thing with your laptop.

Just do your "normal" internet surfing on battery power...and you'll find that you should be getting the approx. 7 hours battery runtime you're supposed to be getting.:)

p.s. Apple specifically says it here (click on the "Tech Specs" tab about halfway down the page):

"Up to 7 hours of wireless web"
