For XO-1.5, "average" is _very_ misleading, because it jumps
significantly between idle suspend and running. Which also means usage
patterns change the overall power use radically.

Modes is a much better statistical tool in this case.

This is similar to current generation smartphones -- a battery charge
will go a long way in idle, or burn rather fast if you're watching
youtube videos or using the gps navigation facilities.
