How can they call 36 hours of battery life "long"? The $799 version Garmin Fenix 7 solar (which they seem to be targeting) has an 18-22 days of battery life.
I totally agree with you as well. I currently have a Garmin Fenix 6 pro and it lasts around 14 days. As someone who is into trail running and backpacking, a 36 hour battery life is untenable, and charging it every night seems like a pain. The irony is that AirPods have a really great battery life (especially the carrying case) despite the small form factor, and are my go-to for long runs.
I don't really want a smartwatch (ugh, slack on my wrist? no thanks), but a backpacking safety companion would be awesome!
