Garbage Collector Over Killing Background Apps

[Ned612]

Does anyone else have issues with their Moto g4 killing background apps that should not be killed? For example, Spotify, Google Maps, and Pocket Cast are all killed if I run them in the background (time delay varies, 30-90 seconds typically), despite having a persistent notification. I have only had this issue on this phone. These applications are not optimized for the battery.

Another question, is there a way to track what is killing apps (to see if it is some unknown app actually killing them)?
