stutter audio with BT headphones after 10 min

I have a problem with my BT headphones.
I have already tried the problem with three different headphones.

The problem is as follows.
The headphones connect successfully and I can play the music (Spotify) successfully.

However, after a certain time (once 10 min, once approx. 20 min) the music starts to stutter. It sounds as if you have run out of range. Of course, it has not changed the range. Watch on my wrist and headphones in my ear.

I simply assume that either the headphones or the watch wants to save some energy and is reducing the BT power. Since it occurs with three headphones from different manufacturers, I suspect it's the watch doing it.
Is there any way to set or prevent this?

  • I'm having a similar issue with my 965. Being in an activity, after 10-15 the music starts stuttering. Pausing the music or skipping a song doesn't help in my case. However, after again 10-15 it starts acting normal again. Then after 10-15 min stuttering again, and repeat. Very annoying i have to say. Never had these problems with my headphones before.
