Question: exercise data no longer accurate after OS4.1 Update

After updating recently to watchOS 4.1 (I've got an Apple Watch 3), my exercise data is now about 25% of what I'm actually doing on a daily basis. Any thoughts?

Hi


If, under watchOS 4.x, your exercise levels are unchanged, but your Activity app estimations have changed significantly, then the following steps may help:


Check your personal information:

  • Actiivity-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 and Nike+ Run Club are set to While Using.
    • Also enable options under System Services including Motion Calibration & Distance, Wi-Fi Networking and Mobile Network Search.


Reset your existing calibration data and recalibrate your Apple Watch:


Check that you are wearing your Apple Watch sufficiently snugly on the top of your wrist:

  • If your Apple Watch is worn too loosely, it can believe that it has been removed, causing activity to not be tracked.
  • For the best performance from your Apple Watch - including the most accurate readings from the heart rate sensor, which is used continually during workouts - be sure to wear your Apple Watch snugly (but not too tightly) during your workouts.
  • Apple suggests tightening your Apple Watch band before workouts and loosening it again afterwards:
