How to change iPhone 11 Battery icon to percentage number?

no, not on an iPhone model with Face ID (the notch)

you can see the percentage in Control Center or you could add a battery widget to the Home Screen or Today View

Increasing on Its Own:

No, though sometimes, it does increase on its own. I've seen it a few times.

So am I. It’s increased before. And you’re right: it doesn’t make sense.

What has increased before? A battery percentage displaying in the upper corner of the screen is binary. It either displays the percentage or it does not. I think you're referring to the charge percentage itself, which is not what the OP was asking

your post does not make any sense. OP is asking about displaying the battery percentage in the upper corner of the screen.
