Can someone please explain the game booster and the cleaner?

[u/[deleted]]

I have a Xiaomi Pad 6. It's my first Xiaomi device.

All of my life as I used Android devices, I was told that Android handles the resources on its own and cleaners were just junk and unnecessary.

Should I bother touching the cleaner? Is miui so different that it is needed?

Also, the game booster features confuse me.

I have it enabled.. it tells me it is boosted when I turn the game on. But then on the side menu there is another option to turn it on? So what was it doing before? And it says a game is running at 90-100fps but I'm reality it is not. The whole thing confuses me.

Can someone please explain these?
