Several Garmin devices also last multiple weeks. My 935 used to go about ~2 weeks and the ones with solar can go even longer. Various usage may decrease this, like detailed gps tracking but I rarely used that functionality.

@[email protected] Nice to have an option that can last over two days as a full featured Android (wear os) solution OR go a week on a single charge as a feature complete fitness tracker.
I wish Samsung would bring that kind of split function to Galaxy Watch.
