I have an iPhone X that is coming up to two years old. I primarily use a wireless charger and generally put the phone on it every other night to charge it right up. Occasionally I'll use a wired charger if I need a quicker charge or are away from home. Battery health is currently at 91%, which from what I can find online is reasonably good for it's age.
I've also read conflicting reports about which charging method is better, but in my experience wireless charging doesn't seem to have an obvious negative impact.
