Imagine you have 20 apps that can send receive notifications from remote (messaging apps, offers, updates…). That would require each app to be active in the background and pulling updates. That’s a massive battery drain.
Instead, the apps send the notifications to Apple/Google, and the OS checks for all of the apps. The apps don’t need to be awake (the OS could show the notification or wake the app) and there’s only one service checking for the ml notifications.
It’s a massive oversimplifying and probably I made some mistakes, but that’s my understanding. Hopefully somebody can correct me.
