Once the battery is charged there is no more load based on it. So there is nil battery harm keeping phone connected to power. But if you disconnect power, the battery is discharging and then suffers a small amount of wear then being recharged.
So if you are near power, and don’t use it, you accelerate battery aging.

Hello!! what is your name?
Cheers @professor the user account has already been raised with the admins to have a word (if there is a real user behind the account).
I am often asking something by myself, but not my own name.
If so I will go to a “dementia center”
I often talk to myself, just not on a public forum
If you are murmuring into your beer glass nobody cares
