In addition to advice from James, you might also want to consider the case when your activity is not in the user focus, as they switch away to a different activity or use one of the home views. A few months back I added some extra event checks to Physics so that it minimises its run loop work when not in focus (updates come from a continious physics simulation so I can't simply idle screen redraws when the user isn't interacting with the UI).
Line 47-49 set up the needed events:
Thanks for thinking about your activity power usage, not much learning can happen on a laptop with a flat battery!
