Heart rate sensor LEDs

Is it just me, or has anyone else noticed that the LEDs for the hear rate monitor are on 24/7? They are not solid, they are flashing, but seem to be on all the time unless taken off wrist. Any else?
  • That's the way it should be. Previous sensors were only sampling every so often to preserve battery but the latest generation of sensors monitor continuously. While in standby/watch mode the LED's will flash but during activity it should be solid.

    ^ yep, the reason battery life is rougly a week (VA3) vs two weeks (VA-HR) is due in large part to the constant HR monitoring, so yes it is on almost all the time if not all the time.

    Ahh ok. Makes sense. That's kinda dumb. I liked it before. Even if it only samples it every minute or 2. That's better than continuously.

    I tried to turn off the HR monitoring to save energy. When I turn off the monitoring, the LED are still flashing all the time. Its impossible for me to turn them off. Does anyone know how to turn off the LEDs completely?

  • Sorry to bump this but my VS4 does this too. When they are blinking rapidly, from your post it means its in standby/watch mode. Does this mean it is still monitoring HR in real time? Because on my app even when LEDs are blinking, the app shows HR changing slighty so I am guessing it is still tracking even when in standby mode? Thanks!

  • Tried it (now) and the LED stops flashing, maybe it's fixed with and an update.

    The LEDs are flashing if the watch recognises movement. If it doesn't notice any movement for a (given period of) time, the LEDs turn off.

    This is why they are flashingwhen you lift the watch from a surface (off of your wrist).

    It is to consume less battery.

    Now came a new sensor update. Everything works fine now. Awesome!

  • Hi Enrico. I turned off heart rate mode and mine still flash continously green.
