Google Fitbit Edge
Up to 7 days of battery at 17.7 g, with built-in GPS. Google gives no GPS-hours figure; DC Rainmaker burned about 8% an hour with the gesture display and 15% with always-on.
6/10
This score is my reading of published evidence, since I haven't worn the band, and it's conservative because one outlet carries nearly all the sport testing. It suits casual runs and rides, but its workout software is thin for structured training.
