I’ve had two iPhones serviced (replaced) due to lightning port failure. I also had few cables replaced due to them getting the surface on the contact pins literally burned by the micro-fires caused by the high-current and the fibre residue of the fabric. So, yours is just as anecdotal as mine. Would actually have to see some numbers comparing Lightning vs USB-C failure rate (on some premium Android smartphones), which we are unlikely to.
