Wi-Fi what do you use it for?

Wifi (on my 935) is great! When I come home after a workout it syncs automatically. 

Isn’t the bluetooth with a connection to my iPhone supposed to do that? Yeah, but the bluetooth connection sucks and it doesn’t reconnect most of the times. Garmin acknowledges the problem but will not or cannot fix it. 

So wifi is great because garmin software is bad. 

I have bluetooth always on and I don't complain. Wifi in my case doesn't start automatically so in my case it isn't any better ️

The wifi on my fenix 5x never automatically synced. And the wifi on my 945 has never automatically synced. Bluetooth always gets there first. I can force it to wifi sync but never does it on it's own. Basically it was a rip-off extra expense on the 5x and hardly any use at all on the 945.

All Wi-Fi features described in manuals - https://www8.garmin.com/manuals/webhelp/forerunner945/EN-US/GUID-7089BCD7-BBA9-4AB1-BE0C-3FA4A2FAE861.html

It has never said that watch will automatically sync via Wi-Fi. But it said that completed and saved activities will automatically upload to GC.

Additionally, I found out that:

1. When BT and Wi-Fi enabled, sync will be performed via BT only. To sync watches via Wi-Fi you need to disabled BT.

2. Sync via Wi-Fi is more faster then via BT, but, maybe, more power consumption.

It's the matter of choice. You prefer BT sync and Garmin Connect. That's fine. I almost never use BT and don't use GC on mobile that much as well. So for me WiFi sync and upload is super convenient and useful. Auto sync when I get back home from run, ride within a few minutes.

So yes, I use WiFi on 935 and now on 945 just for sync.
