Unexpected battery drain these last couple of days, and trying to narrow down the cause. One thought is that the music is still 'on' when the playlist is loaded even though no headphones are connected. Is it necessary to turn music off somehow in the watch, beyond just pausing it and disconnecting headphones? There is a logout button press on the Amazon Music app; do I have to logout every time? I want to be sure that I am not using the watch with music on constantly, even though I am not listening to it.
