Hi
The following steps may help (check after each):
If you have not yet done so, update your iPhone and Apple Watch to the latest compatible software versions, starting with your iPhone:
- Update the iOS on your iPhone, iPad, or iPod touch - Apple Support
- Update your Apple Watch - Apple Support
On your iPhone, in the Watch app, go to: My Watch > Privacy - check that Fitness Tracking and Heart Rate are enabled.
On your iPhone, in the Watch app, go to: My Watch > Workout - turn off Power Saving Mode.
Check that Wrist Detection is turned on and that, if passcode is enabled, you are unlocking your Apple Watch after placing it on your wrist:
- On your iPhone, in the Watch app, go to: My Watch (tab) > Passcode > turn Wrist Detection on.
- Note that Wrist Detection can be affected by temporary or permanent skin changes, such as by some wrist tattoos.
Check that you are wearing your Apple Watch sufficiently snugly on the top of your wrist (it may otherwise believe that it has been removed, causing it to lock):
Close certain apps and then restart (normally) both your iPhone and your Apple Watch:
- Close the Watch app, Activity app and Health app (if open) on your iPhone:
- Double-click the Home button, then swipe up on each app preview to close the apps.
- Close the Workout app, Activity app and Heart Rate app on your Apple Watch:
- Turn both devices off together, then restart your iPhone first:
If you have previously used any third-party fitness tracking, sleep tracking or heart rate monitoring apps:
- Check whether there is an active or paused session within any of them.
- If there is, then end that session from within that app on your Apple Watch.
- If in doubt, it may help to remove any such third-party apps from your Apple Watch, at least temporarily.
If the issue persists, then it may help to unpair and re-pair your Apple Watch:
- The Watch app on your iPhone takes a backup of your watch automatically when unpairing via the app.
- Initially choose to Restore from Backup during set up (most data and settings will be restored, with some exceptions, such as Apple Pay cards, passcode).
- If the issue persists, consider instead unpairing and setting it up as a new watch.
- Unpair your Apple Watch and iPhone - Apple Support
- Set up your Apple Watch - Apple Support
If the issue persists, then I suggest that you contact Apple Support (remote diagnostics and/or mail-in service may be available, if required), make a Genius Bar reservation or visit an Apple Authorised Service Provider for assistance:
