How to fix random restarts on Apple Watch Ultra 4?

Step 1. Force Restart.

According to Apple:

To force restart your Apple Watch, press and hold both the side button and Digital Crown for at least 10 seconds, then release both buttons when you see the Apple logo ().

Step 2. Reset Watch.

How to reset your Apple Watch:



1. Put your watch on its charger and keep it there until you complete these steps.
2. Press and hold the side button until you see Power Off.
3. Press and hold the Digital Crown until you see Erase all content and settings.
4. Tap Reset, then tap Reset again to confirm.
5. Wait for the process to finish, then set up your Apple Watch again. When asked, restore from a backup.

NOTE — Erasing all content and settings erases all media, data, and settings from your Apple Watch, but it does not remove Activation Lock. To remove Activation Lock, unpair the watch first. Before your watch is erased, a backup of its contents is created on your iPhone.

Step 3. Connect Watch.

Then make sure both devices are in close proximity with the following settings:

• AirPlane turned off
• WiFi turned on
• Bluetooth turned on

Click ▶︎ Connect/Pair your Watch for detailed instructions.

Just got the new ultra 4, and it keeps restarting. Happened at least 2 times a day, and yesterday it happened during a run, which completely ruined the tracking.

anyone else experiencing the same issue?

Original Title: Ultra 4 randomly restarting

I would try a force restart, by holding both buttons on the right side in together for at least 10 seconds.

If that does not help, then I would return the watch which you can do within 14 days or purchase to have it replaced with a watch that does not restart randomly like that.

Your suggestion will not help anything.

Judging from a quick google on web forums and reading some, this is a widespread problem. I've had two random reboots so far without having done anything. Sometimes, new Apple products have issues in the first few weeks that will get fixed in the next OS update. I'll be waiting for that.
