I've read topics about this already, but they are old for over years and still this haven't been fixed? I saw that it's some kind of 'Spotify Connect' service that drains it so much but, force stopping in settimgs appareantly fixes this but only when the app is off. I still can't listen without this massive battery drain. It uses approx. 1% per minute, which is crazy.
