Wireless charging always generates more heat than wired charging but it’s not always a significant amount.

Wired charging ports get dirty, wear out

Batteries last longer with slower charges.

Batteries last longer with less charges

Batteries last longer If they never leave a moderate temperature.

Batteries last longer if they never drop below 20% and never go above 80%

Batteries last longer when stored if they are stored at 50% charge.

Putting that all in check you can take a couple year old phone to a fix it place and have the battery replaced. And they can also replace your wired charging port if necessary.
