After being fully charged, Keen's battery should last a minimum of 20 hours of wear time.  Power-saving techniques that reduce battery use when Keen isn't moving have been implemented, such as when your arm is still or Keen is removed from your arm and sitting on a surface.  The battery lasts on average 2 days, with the number of vibrations not making a major difference.
