Hi, I just created a second watch face for navigation, with compass, maps, and tides on the Sun Dial face. Being battery obsessed, I’d like to know if these complications and the watch face will be taxing the battery when they are not visible as the second face. Thanks!
I don’t believe they do.
I have a face I don’t use very often, which has the built-in complication that shows the day of the month.
When I switch to this face, it always shows the day of the month when I last used that face, for about half a second, before it updates to today’s date.
Because of this, I don’t believe that the complication runs when the face isn’t showing.
