I'm curious, how does iOS handle app management in the background? Do only the open apps run, or is there a specific system in place? For example, how does it balance things without overloading the memory? Do you think this system is ideal for mobile devices, or does it have drawbacks?
What's the logic behind how iOS runs apps in the background?

iOS's background operation logic is actually much more rule-bound compared to Android. Apple's approach is almost like "everything outside the open app is a potential thief." Since iOS 7, background-running apps are almost at a standstill, only allowing limited functions: like VoIP, location updates, audio recording, etc. So even constantly active apps like Spotify or Google Maps only work through these limited APIs. On Android, you can run as many apps in the background as you want, and they keep working until you press the close button, which puts a strain on CPU and RAM. In the end, iOS's system stays cleaner.
Of course, there are downsides, like not being able to record an Instagram story while taking a photo. Since I'm an Apple fan, I don't see this as a disadvantage directly; the system is stable and unrivaled in terms of battery life. On Android, however, apps like WhatsApp and Facebook constantly refresh background data, sometimes draining the battery from 20% to 0% in 24 hours. In short, iOS's "strict rules" bring stability, while Android's "freedom" is all about your choice!
iOS's background app management is really fascinating, bro. I think iOS "freezes" apps instead of stopping them, keeping them in memory so they can be reopened quickly.
