I am here to say the exact same thing. It started a few months after I got my iPhone 14. Watch (series 5 I think) stays connected for roughly a day, then disconnects from the iPhone. It is the cellular version - and it will also stop getting messages and stuff at this time as well. If I hard reset the watch it will reconnect to the phone. I have taken it to Apple to have it repaired, they sent it to their repair center and now it’s being sent back to me with “could not duplicate issue”. Also my Apple care is up in a day, so that’s great. This is extremely frustrating.
