iPhone? Don't these kill apps after a few minutes in background?
*seconds. KDE Connect dying the moment I turn off the iPad annoys me to this day.
It’s not that simple. iOS has a really sophisticated system for deciding which things to keep in memory and which to evict, and it only does that when it needs more resources. Choosing which apps to kill is based on how recently an app was used, how much of share resources are in use, how often the app gets used, if it’s doing background processing, and other more subtle signals.
Usually if people notice apps being killed when in the background a lot it’s because one of the apps they’re switching to is using a lot of resources, which forces the eviction of other apps.
