alt Hacker News> With fast charging, battery life hasn't been an issue
I sold my 10 last year and haven’t missed it. You don’t have reasonable access to a charger during a marathon or a long hike, the latter of which needed me to charge my Apple Watch 3 times over the course of 12 hours of hiking.
Did a long bike ride recently and just used my iPhone to track the workout. Probably suboptimal, since it doesn't have all the heart rate stuff, but it gets the big picture (elevation gain, speed, distance).
