Yeah. The PSP runs out of batterys in 2 hours if you watch a movie, and in wifi internet its only a few hours more. What do you expect, man? This thing with the power on an N 60 - freakin - 4 is racing people accross the world via wireless internet! Of course it's gonna take more battery life! But if you honestly play your DS so much that you have to charge it daily, consider giving your social life a good CPR session.
