Default Asphalt HD always in battery consumption screen

Anybody got this game from gameloft? It is one of my favorite games on iOS and I like the graphics on my Sensation especially with the bigger screen.

There is only one quirky though, when I check the battery status screen I can see that it is the only app listed there with 6% consumption second to display at 86%. Is this normal for an app to be consuming battery even if I killed it's a process?
