Better close them all! Have a clean system… 😅In theory, yes.
in practice if I have multiple streaming apps like Times Radio and Spotify in the background they can co conspire to run together snd use loads of battery. Hard to reproduce but it has happened.
Personally I close them all occasionally, and nobody can persuade me that having 35 apps in the background uses no resources. RAM surely?
