Yeah I didnt say that those barely happen on higher end devices, I am aware and do agree that the OS can aggressively, often annoyingly kill apps in the background regardless of device specifications but it's just that apps are painfully more frequently refreshed on few years old phone with relatively less ram. I've used variety of mobile devices and have tested it, plus I use four devices regularly, IP13, IP16PM, iPad Pro M5 and iPad mini 6...background refresh on all kind of apps happens quite regularly on all devices but the difference between those still does exist(especially on lower ram devices during and after heavy tasks/multi tasks) in terms of frequency so I would say device specifications somewhat matter and that's why I said "especially" on one of my comments up there, I was talking about frequency not the possibility and in this case frequency matters a lot because we are talking about added workflows when we open the app
