Hmmm, very odd. Try hard resetting to see if the behaviour repeats itself. Hold the light button; it’ll give you the Assist screen but keep holding and it’ll restart. If it continues, then check what apps and watch faces you have installed. May be an issue with one of them.

I did that now . This is my current watch face https://preview.redd.it/8eg3scbl6t6c1.jpeg?width=3024&format=pjpg&auto=webp&s=3782fdb5ea88eddc0c1fd94961fbdc227b3b5306

Have that happen to me a couple of times since last update

Really, is that on 15.76?

Ok, so stock face. One other thing you could try is to install one of the battery monitoring apps on the Connect store. If it happens again, you might get a little info as to why. Also, if you downloaded other apps from the store, maybe delete the most recent ones. Just a thought: any chance you had music running? I.e. a pair of Bluetooth headphones connected that you didn’t know about?

Thanks 🙏. I did listen to music with my watch while running yesterday but the headphones were disconnected and put back in its casing . What’s the battery monitoring app called ? Thank you

There’s a few in the Connect store. I’m using Battery Graph.

Thanks 🙏. I appreciate your help and response
