I am attaching my observations and measurements.
I have already completed two cycles from 100% charge to the next charge.
In the first cycle, there was an interesting break in consumption after the first recording of activity with the Suunto Smart HR Belt (I later bought a new chest strap).

In the second cycle, the exact opposite phenomenon occurred: after a sharp discharge, a change occurred and the discharge slowed down.

In addition to the soft reset, I removed the old paired HR belt at that time, as during one activity, the connection with the new HR belt did not start up.
I would like to add that before the last update (2.48.16), when using the watch a little more, I charged it after 10 days when the battery level was slightly above 30%.
Otherwise, I didn’t change my usage. I had continuous heat measurement, sleep tracking, smartphone notifications, brightness = medium, and Raise to wake = Low turned on.
