No more, or no less than other activities on the device. The battery health of all devices will always degrade with time and use.

There is evidence that repeated fast charging at higher voltages will shorten the overall life of a lithium ion battery. In other words if you’re a hardcore gamer running on battery and are daily fast charging your battery, it will wear out quicker.
