Galaxy watch 3 won't stay powered on

S21 phone & watch3

Just did a factory reset on my S21 3 days ago.  No change on the watch.

After 3-5 hours my watch powers off.  I power it back on, get the Samsung logo, and the watch powers off again.  When I attach it to the charger, the watch scree has shown 31% 1st day and 46% today.

Why is my watch powering off. How do I resolve this.

Reset your watch

Well, that didn't work.  Reset.  The watch powers up to a yellow? screen "Let's Go."  Touching or swiping that results in something similar to 'Start on the Galaxy app on your phone.'  Open the phone app and see "Connect."  Touch that and the watch powers off.  Power watch back on and now I'm in an endless loop.  Now what?

Try to perform a wipe Cache partition.

Did this work to get your watch working properly!

No.  My watch turned off on it's own.  When I put the watch on the charger, it showed it was already 31% charged and 46% charged.
