Why can't I get maximum brightness on my iPhone?

I'm using iPhone se.

Even though I'm using it with maximum brightness, the brightness keeps decreasing when I use it.

Why is that?

Is there a way to fix it to the maximum brightness?

I turned off the automatic light, but it's like that

It's because of Throttling
It's because of the heat and other reasons, the performance is limited
