What the hell are you smoking? First of all, I agree, UFC is the most badass sport out there, but what's all this about soccer being "true athleticism?" Running around and kicking a ball doesn't take much.
I have the Verizon White Chocolate phone, and my battery lasts for like a day and half without charging it. Have you looked to see if you can get like, a bigger battery? Most phones have a larger battery you can buy.
I remember playing the original Pokemon Red for the whole day, a few times. I'd go to a friends house (which was really stupid cause no one said a word outside of "I CAUGHT IT!") and we'd all sit on the couch with extra batteries and soda and stuff.
