Animation/Python/PyGames vs battery charge

[Kent Loobey]

I have set up some test animation code.

Normally games try to take all the cycles they can get.

I am trying to preserve as much battery energy as I can.

So I am setting a specific frame rate and sleeping beyond what it takes to 
maintain that frame rate.

Do you think this will actually reduce the drain on the XO battery?

In other words "What does the XO do when apps sleep?"
