Ignoring that Spotify uses approx 20% per hour of the battery during offline/streaming playback I have noticed that the Spotify App always seems to be running and according to my 'test' outlined below uses 5%+ of a full charge even if you never open the app. This seems wrong to me.
Full Charge without Spotify Installed
Spotify Installed, watched switched off battery recharged to 100% and then switched on.
After 1.5 days normal Usage - 56% battery used - 12% on Spotify despite the app not being opened. That is 6% of full charge going on an app that is never opened (nor added as f widget) etc.
Surely this is a bug???

I can now confirm since my recent restart/installation I get no carryover or excessive battery drain when Spotify is not in use.
In-use drain is "okay" when you consider that a mobile can use several % when streaming Spotify by Bluetooth. Would be good though if they could reduce it further obviously.

I made a little research:

Hope this helps!
