EYE ICON AFTER RUNNING ACTIVITY

Hi everybody!

I recently did a running activity with the LTE connection activated, as I always do.

After stopping and saving the running activity, the watch showed me an icon I had never seen before, a kind of "eye." Does anyone know what it means?

On the other hand, I noticed a very rapid loss of battery and the watch constantly notified me to activate power saving mode (when it still had 43% battery).

I imagine it's a (another) clock bug...

Thanks for your help!
