When your have paired a HR Belt with your Fenix 5 and you start an activity, does the wrist HRM automatically turn off to save power?

Thanks, And Watch will only try to connect to (search for) HR belt when I start an activity?
Yes, short answer. Long answer, ANT+ radio is off when in low power mode (watch mode), unless you go into widgets which turn it on. When you start an activity, the ANT+ radio runs in search mode to find the sensors quickly, then runs in a lower power mode through the rest of the activity.
