18-hour battery life still does not cut it. I would say you need, at a minimum, double that to make it competitive with the likes of say a Garmin.
But, at $400, it is attractively priced and, as always, looks impressive.
Not sure why Apple struggles so with battery life. Some folks are now getting 2-weeks.
But, this is good for us Garmin fans. We can still make fun and look down our noses at Apple Watch wearers.
