Answer 1

Water will short the charging port, so the phone looks for a short. If the phone detects a short, it says “hey there’s a short. That probably means there’s water in the port, so I’m gonna turn off the port until the short goes away”

No damage is done as long as the moisture doesn’t exist in the port while it’s on.
