@fedequei Sorry, English isn’t my native language: I may not have been clear.
That’s exactly right, it’s the swipe up from the control bar at the bottom of the home screen. You’ll see that your watch no longer syncs automatically, so the weather widget may no longer be up to date, and activities no longer sync automatically at the end of the activity, but doing it once a day is enough.
My routine has become: I get up in the morning, synchronise the watch for the weather widget and sleep tracking, then manually close the app. Then, if I’ve been running or doing an activity, I synchronise again.
Basically, I’ve gone from multiple automatic synchronisations per day to two manual synchronisations. This obviously has an impact on the battery.
