The Health app doesn't turn off the HRM when the watch is motionless, BUT the HRM itself (in Bangle.js 2) detects when it's not in contact with the skin and goes into a low power mode (you'll see if doesn't flash green unless it's very close to your skin) - so actually the power consumption is tiny if the Bangle is just sitting on your desk.

Ah, that makes sense why I couldn't see any code for this - it's implemented at a lower level (hardware or HRM integrated firmware). That's pretty cool.

Thank you for explaining!
