Symptoms
- Step count is much lower than expected during a normal day
- No steps recorded despite walking with the watch on
- Steps count while sitting still (phantom steps)
- Step count resets or stops syncing
Likely causes
- CommonWatch worn too loose to sense arm motion accuratelyThe accelerometer relies on consistent wrist movement patterns.
- CommonActivity type doesn't match natural arm swingPushing a stroller or cart, or holding a bag, suppresses the wrist motion steps are counted from.
- PossibleSync issue between watch and companion appSteps can be recorded correctly on the watch but fail to appear in the app.
- Less commonMotion sensor calibration driftRarely, the accelerometer itself needs recalibration after a drop or long use.
What to do
- Make sure the watch is snug enough that it moves with your wrist, not loose on your arm.
- Open the companion app and force a manual sync to pull the latest step data.
- Check the activity or workout mode isn't set to something that ignores step counting, like 'strength' or 'other'.
- Restart the watch to clear any stuck sensor processes.
- If you're pushing a cart or stroller, expect undercounting since that's a known limitation of wrist-based tracking.
- Update the watch's firmware and companion app to the latest versions.
When to call a pro
Persistent inaccurate counts after fit adjustments and updates are usually a minor cosmetic issue, but contact the manufacturer if steps stop recording entirely.
