Hi
If your exercise intensity levels are unchanged and you are now being credited with significantly different levels of Active calories, then the following steps may help:
Check your personal information:
- Activity-related estimations depend, in part, on your personal information.
- To check that this is accurate:
- On your iPhone, in the Watch app, go to: My Watch (tab) > Health > Edit - tap and adjust items, then tap on Done.
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, check that Apple Watch Workout is set to While Using.
- Also enable options under System Services including Motion Calibration & Distance, Wi-Fi Networking and Mobile Network Search.
- If the settings are already enabled, try briefly turning them off and then back again.
Reset your existing calibration data and recalibrate your Apple Watch:
- Calibration can improve the accuracy of estimations made by Activity app and Workout app.
- More information and instructions are available via the link below:
