iOS 13 iPhone music app constantly crashing, causing freezes, phone getting hot
Apple music subscriber here.
Never had these problems until iOS 13 and iPhone XR. Right up until the XR I had an iPhone 8 Plus.
I recently bought an iPhone XR and right from the first day it was getting unacceptably hot and music app misbehaved (crashing, not playing music, carplay music not working).
Did a settings erase and still having the problems.
Took it to genius bar and did a hardware test (all ok) then turned off background app refresh for all apps. Still problems.
Did a factory reset. Still the problems.
Setup as new phone (no restore from backup). Still the problems.
Discovered that music app has background activity, even when phone is not in use (music app or otherwise). To the point that when I detected my phone getting hot I would note the battery use for the music app, ten minutes later it will have had an extra 10 mins background activity. A couple of times it will have had a few hours background activity.
The only remedy seemed to be to switch the phone off and on again, and sometimes that didn't even work.
Then it started happening to my wife's year-old iPhone 8 Plus. With severe battery drain.
Back in the genius bar, the music app was deleted and reinstalled from my new XR. Suggested that it could be the sync with my music library of over 15,000 songs that is causing the problem.
Left sync off for around 4 days. No problems.
Turned sync on. Problems started again after a few days.
Turned sync off again. The problems now occurred with sync off.
I've now turned sync on because my chosen playlists don't sync with my Apple Watch series 4 without sync on.
I'm out of ideas as to what is causing it and what to do. Any help is appreciated.
Incidentally, my wife's phone isn't linked to the same iCloud library as mine. Her library is probably less than 2,000 songs. She also uses Apple Music and has a series 4 Apple Watch.
