Now I have restarted the iPhone and the Apple Watch and the connection works again. It is interesting that the battery consumption is now also normal again, i.e. as before. I conclude from this that the watch previously always tried unsuccessfully to establish the connection and that this led to the increased consumption.
So the problem is solved.
