This started happening to my Apple Watch 1 series sport when I upgraded phones to the i-phone XR.


I contacted Apple support and discovered that there is a recent iOS upgrade to 13.6 (issue was occuring with 13.5.1).


I'm happy to say that following an update on the phone and a un-pairing and re-pairing exercise the watch is working as expected (so far).

I’ve been having the same problem with the series 3 watch paired to an iPhone 7 running the accursed iOS13. It’s not happening daily (that I’ve noticed), but appears to be completely random. The “syncing circle” can take over an hour to finish, and usually doesn’t complete fully before restarting once or twice. There doesn’t seem to be any pattern to it, the sync will start on its own whether the watch is on the charger or not, and there is no pending software upgrade.

I’ve been having the same problem. I’ve had a Apple Watch series 1 for many years, currently synced to an iPhone 7 which has been working solidly until a few weeks ago when it decided to sync while wearing it. It’s currently doing it again while wearing and has gone thru one complete sync circle and is now going thru a second sync circle. Seems to be no rhyme or reason why this happens except that it has to be the last IOS update. Was going to get rid of the series 1 thinking obsolete but seems later models are having the same issue.

I am also having this issue. It began when I was traveling in late December, so I assumed something had gone wrong with an update when the sync wheel came on during a run. I reset the watch to factory settings and set it up as a new watch. This seemed to have resolved the problem for about a week before the sync wheel presented itself again and has continued to happen intermittently for the last few weeks. Just yesterday the sync wheel popped up again, but finished a revolution in about an hour, so I didn't reset. This morning shortly after starting a workout the sync wheel reappeared, so I reset to factory default yet again and as I write this thread the watch is locked up syncing for the second time today after reset. I really wish Apple would address this issue.

I notice EVERY morning that I get my phone I have to enter my pass code because the phone is apparently rebooting EVERY single night! So in my opinion the current operating system 6 for the watches ain't working with ios 13 for the phones. IOS 13 SUCKS!! I hate it and I pray everyday a fix comes out to fix it all. ALSO, my watch used to be fine for battery life for a whole day, and now I get the 10% warning every night! I've done everything to increase battery life, and nothing works. And this is all after ONLY updating the watch and it stopped being as good as it used to. I'm so sick and disgusted. I hate even complaining cause I don't want to hear it from Android heads....

Same thing is happening to my wife and I once or twice per week. Both running Apple Watch S4 and iPhone 7 (hers is a 7 plus). Pretty annoying, especially during workouts. Hard to rely on having your watch as a standalone cellular device (leaving phone at home) when you have to worry about whether it's going to be unusable for an hour at a time.

Hi Jettsica,

You and I are on the same devices, series 1 watch, iPhone 7. I am now running IOS 13.3.1 right after my last post and the watch hasn’t updated on me yet..


Before the iOS update, my reset only happened twice about 6 weeks apart.. yours was still syncing daily. There must be some other factor going on that we’re not aware of. Hope 13.3.1 works for you.
