Spotify killing the better without use.

[The Lonely Loner]

 Went to sleep with about 90% , woke up with 40%. Bluetooth was off and every "automatic feature" as well. Spotify ate through the battery while asleep. What should I do? This is the first time it happened on my Watch 5.

Uninstall Spotify if it's draining your battery that much during the night while you are sleeping

Try going spotify settings
And don't allow spotify to run in the background

@The Lonely Loner  certainly ensure that  spotify is not running in the background and check you have the latest version.  It may also be a good idea to turn of location services for the app if activated, spotify connect uses more Battery and so it is advisable to turn that  option off.
