You do, but not necessarily. It all depends what kind of battery the particular laptop offers, and how much you are underclocking the chip. It's almost the same as a P4-Mobile.
I have a 12" screen, <3 lb. Centrino 1.5ghz Laptop by Asus, and it's amazingly portable. The battery life I get on 75% CPU is almost 2 hours. If I opted for the extended battery pack, it is said to do up to 7+ hours.
P.S. Keep in mind also, that the Centrino 1.5ghz is equivalent to a Pentium 4 2.4+
