Watch 3, calories burnt is too high!!

Hi

If you are concerned that your calorie estimations are inaccurate, then it may help to follow these steps:

If you have not yet done so, update your iPhone and Apple Watch to the latest software, starting with your iPhone:

• Update the iOS on your iPhone, iPad, or iPod touch - Apple Support
• Update your Apple Watch - Apple Support

Check your personal information:

• Calorie estimations depend, in part, on your personal information.
• To check that this is accurate - and to update it over time:
  • On your iPhone, in the Watch app, go to: My Watch (tab) > Health > Edit - tap and adjust items, then tap on Done.

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:
  • If an app unexpectedly quits, stops responding, or won’t open - Apple Support
• Turn both devices off together, then restart your iPhone first:
  • Restart your iPhone, iPad, or iPod touch - Apple Support
  • Restart your Apple Watch - Apple Support

If you have previously used any third-party fitness tracking, sleep tracking or heart rate monitoring apps:

• Check the developers' support resources and/or contact the developers to check for any known issues affecting how data is shared to the Health app on your iPhone.
• 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.

Prior to calibrating your Apple Watch (see the next step), check your Location Services settings:

• On your iPhone, go to: Settings > Privacy > Location Services:
  • Check that Location Services (the main setting at the top) is turned on.
  • In the list of apps beneath, if Apple Watch Workout is listed, then set it to While Using.
  • Also enable options under System Services including Motion Calibration & Distance, Wi-Fi Networking and Mobile Network Search.

Calibrate your Apple Watch, resetting any existing calibration data and starting afresh:

• Follow the instructions here (this process can be equally beneficial for Series 2 & 3 models):
• Calibrating your Apple Watch for improved Workout and Activity accuracy - Apple Support

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:
