iOS background activity for Music draining battery
Even after closing Apple Music, disabling music sync, and background app refresh for Music the battery drains quickly. All I use Music for is streaming a radio station, Lightning 100 while I'm in the car via Car Play and about a total of 20 minutes per day. It charges while in the car. So possibly something in the background caused by Car Play? In the end, I tried every solution I could find online and the problem continued. So, I had to remove the Apple Music app. Not an ideal solution, but better than a dead battery at the end of the day.
