does overcharging F15 cause damage to my battery?

just bought it a month ago and I always charge it even when it's full because I've heard it is fine for modern laptops to keep overcharging it but just recently I've heard it is bad even with modern laptops to continue overcharging it.

I want to preserve my battery health as much as possible because I would use it for college in the future, should I kept it plugged in when it was on or charge only when needed?
