How do I know if I can charge fast or not on an iPhone?

I came over to iPhone.

And phone marked whether it was a fast charge, but

I can't tell because it's not displayed on iPhone.

I need to check the charging time
If it takes 30 minutes to charge from 0 to 50%, you can think of it as a fast charge
And after that, it slows down, and it takes quite a long time to get to 100 over 90
