How do Android apps stop automatically when we get out of them?
If on Windows we're used to shutting down apps when we get out of it, things are totally different on Android.
The Android operating system automatically manages applications that are stored in memory.
Sometimes the Android system decides which apps to keep in memory and to close them.

Why does RAM load on some phones?
There are many reasons:
1. Insufficient RAM (below 2-3 GB of RAM)
2. Bug applications that consume excessive RAM
3. The phone manufacturer did not optimize the ROM for efficient memory management

If RAM is being used excessively, what can we do?
If you have little RAM, or your rom is not optimized for efficient RAM management, you can set your phone to stop applications as soon as you exit them.
This solution, which automatically shuts down applications when it comes out, is also useful when we want to save battery - It is known that a charged RAM consumes the battery quite a bit.

How do I stop applications on my Android phone automatically?
In Developer Options, on your phone, you have two options that you can automatically shut down running applications when you exit them, or keep 1, 2, 3 or 4 processes in the background - I refer to some applications that you Use more often.

Advantages of automatically shutting down applications at the output.
1. Less power consumption of RAM
2. Power saving (battery)
3. Running heavier applications requiring RAM
Disadvantages of automatic shutdown of applications at the output.
1. Apps will reload each time from 0
2. If you do something in an application and exit, it may lose what has not been saved.
