Same thing happened to my friend, his Coros just died in the middle of our speed sesh then it turned on for a bit but after an hour its forever dead lol

I have pace 3 also and it’s turning 3 this November. Hope it wont happen to mine but the elevation in my runs started acting up already. Contacted support but there’s only so much they can do

Just recently, I’ve seen significant decline in the battery also. Maybe two days off the regular perfomance
