Green Light WIll Not Turn Off

Green light back of the watch stays on until it kills the battery. Have turned off heart monitor and that does stop the green light but then I have no heart monitor. Could anyone suggest additional steps to try? Please.

An active or frozen workout session is the most common reason the optical heart sensor stays locked in continuous-measurement mode.

  • Open the Workout app on your Apple Watch to see if a workout is currently running in the background. If one is paused or active, end or finish it. 
  • Check other third-party fitness apps you use (such as Strava or Nike Run Club) to ensure they aren't stuck trying to write live heart rate data or keep a session open.

Thank you so much WheelieNick! Your advice worked! Peaceful again with a proper heart monitoring light. Many thanks!
