The phone is running on stock Android version 5.1.1. On my previous Galaxy S4 (different ROMs) I have had no issues.
I have not installed any Purify or other 3rd party battery optimizer. AFIAK my system optimizer is turned off as well. Any idea what causing it?
I found two other people had the same issue (one for LAN plugin and other for Drive plugin):
