I’d shell out $800 for an ultra if it got 3 full days of battery life without having to use a power saving mode. Until then, I’ll stick with my Garmin. 14 days of battery life if you don’t workout and if you workout 3 or 4 days a week, it’s closer to 10 days.
So, I’ve got an ultra and I legitimately charge it once every three days. Everything turned on and a couple of GPS workouts.
So more than advertised, I know. But I’ve been hooked to my Garmin Fenix 6X Pro Sapphire and now I’m not looking back since I got the ultra. It is a smart watch. Not just something that shows a notification every once in a while.
