In fact, there is room for changing time in the program. For example, if you open 10 programs and let them all occupy memory, then you will switch these 10 programs very quickly. If the memory is cleared, it will be reloaded when switching, but it will be slow. So the conclusion is that unless the memory is not enough, there is no need to clean it up and use it quickly.

Android and ios have different backgrounds. Android has many application backgrounds, and each application has its own process. If there are too many programs, there will be more cards in the background. Take ios as an example, qq and other messaging applications have a unified message background, and the program actually closes as soon as it returns to the main interface, so it is relatively smooth. Of course, their respective characteristics are only their shortcomings. Android consumes power and cards, but the background independence of messaging applications means that it can respond quickly. In the case of ios, there will be a short delay in information. But Android is also improving, and stacking hardware is also a way to make it smooth.

Basically, I have seen the Android card of the processor above Xiaolong 800.
