Do android animations use a lot more CPU power?

Question

I am using Animations in my application while

1. switching among Activities
2. populating ListView.

now I am wondering if it uses a lot more CPU power which uses more Battery.

Thanks.

Answer 1

Well, any calculation by the cpu uses power, and I have to believe that you have to do a lot more calculation to animate those items, so I would say yes, it would affect the battery life.

I can't imagine it would be drastic though... people use Live Wallpapers, and some searching on the nets shows that those (depending on the device) can use an extra 2-4% power, and that's for something that runs 100% of the time when visible, as opposed to list creation which happens in a finite amount of time.

Upshot: I wouldn't worry about it.
