I just purchased a Garmin Fenix 6x and wanted to learn how it could help me train. So I created a custom workout using the Connect web interface and clicked on "Send to Device". This launched Garmin Express so I plugged my watch into my computer so that it could find the watch.
After doing this, the watch face change to a screen showing a percentage. I thought this was showing what is being downloading given that was the reason I plugged in my device. This took a very long time for the the watch face to show 100%, well over an hour. But I didn't want to disturb the download because I figured this was some update from Garmin.
What I have since found out is this percentage was showing the battery being charged not a download. That meant I could have safely unplugged my phone and charged at a later time. Given that Garmin Express has god-like knowledge of the internals of their devices; it clearly understands that the device is being charged.
I really wish that Garmin would clearly state this in the UI for Garmin Express so that new users like me understand that they can unplug the device from the computer.
One idea would be to add a battery/charging status to the UI Ribbon at the top of Garmin Express that is shows the currently connected device.
thx
