For two mornings when I put on my watch there were two green lights on the back. They have never appear d before, and yesterday for the first time ever my watch showed low battery before the end of the day. Why are these lights on? How do I turn them off?
Hi
The green LEDs are used by the heart rate sensor. It is normal for the sensor to take background measurements of your heart rate regularly throughout the day, but the LEDs do not remain permanently lit for this purpose.
It should not typically be possible to see the LEDs. For the best performance from your Apple Watch, check that you are wearing your watch sufficiently snugly on the top of your wrist.
Your heart rate. What it means, and where on Apple Watch you’ll find it. - Apple Support
If the LEDs are permanently lit, you may have a workout or other fitness-based session in progress (there may also be a runner icon on your watch face).
In the Workout app - and also any third-party fitness tracking app that you may have installed - be sure to end any workout that is currently paused or in progress:
If the icon remains / the LEDs remain lit up after ending any active workout, restart your watch:

Wow! Thanks for the extremely helpful answer. That solved my problem. I had paused instead of stopped the workout app.
You're most welcome! 🙂
