Battery efficiency questions in the context of running

However, I guess I'm not factoring in the battery usage from the Run app updating every second, so that could definitely be a bit of a hit to battery life.

I don't remember how redraws are done in run but maybe we add a setting for the redraw interval? I'm thinking 1 (or 'on new data'...), 2, 3, 5, 10 seconds - as choices.
