What to do if the screen goes black after the upgrade progress bar is loaded and it takes a few minutes to power on when upgrading my Xiaomi Watch S3 to a new version?
Since the watch supports built-in Applications, after the watch loads the upgrade progress bar, the watch software still needs to load, decompress, and install the resources of the watch Application, so the upgrade progress bar will appear. It is normal for the watch to remain black for about 1 to 3 minutes before turning on and displaying the startup screen.
Does it help?
