Battery Saver: Keep Heart Rate Sensor On

Howdy,

I just upgraded from a Venu 2 to a Venu 3 and I was surprised to see that the Heart Rate Sensor is turned off in Battery Saver mode. This functionally turns the watch into a step counter / clock. The Venu 2 did NOT shut the Heart Rate Sensor off during Battery Saver mode and I found this to be immensely useful to prolong battery life.

Why was this option not maintained for the Venu 3? It makes Battery Saver almost useless.
