F7, leaving wifi always on

Premise: I would like to use only Garmin Connect via the web, and I intend to leave enabled the wifi all the time on the watch to synchronize things.

I did a simple test at home, leaving WiFi on the watch enabled all day and turning on logging on the router to see how often a connection is established with the watch. I saw that the connection is established only when:

  • I perform a manual synchronization
  • I save a workout and am in close proximity to the WiFi network
  • I've saved a workout but have not yet synchronized; as soon as I am near the WiFi network, the synchronization starts.

I've read in several posts that the WiFi on the watch keeps polling, but that doesn't seem to be the case also because I don't see any impact on the battery. Am I wrong?

TIA
