If your Apple Watch Series 11 intermittently stops displaying your heart rate during workouts, it could be a sensor-contact issue or a software problem.


I'd try these checks:

  1. Check the fit: Wear the watch snugly, just above your wrist bone. It may need to be slightly tighter during exercise.
  2. Clean the sensors: Wipe the back of the watch and your wrist clean and dry, especially after sweating.
  3. Check Heart Rate settings: On the watch, go to Settings -> Privacy & Security -> Health ->Heart Rate and make sure it is enabled.
  4. Check workout settings: On your iPhone, open Watch -> Workout and check whether Low Power Mode is enabled. Temporarily turn it off for testing.
  5. Restart both devices: Restart your iPhone and Apple Watch, then test another workout.
