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 updating the Xiaomi Watch S3 to a new version?
For the issue you encountered, here is some information for your reference below:
Since the watch supports built-in applications, after the watch loads the update progress bar, the watch still needs to load, decompress, and install the resources of the watch apps, so the update 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. Please wait for a while with patience for the watch to reboot.
