Wireless charging isn't immune to failures either. A recent example of this is Google's Pixel 4 device, introduced in Oct. 2019. Apparently if the phone chassis expands over time, the rear antennas (including wireless charging and NFC) get disconnected and stop working. People experiencing this issue, including myself, are not able to reliably use wireless charging, and using NFC (e.g. for Google Pay) requires us to put pressure on the rear of the phone.
Granted, Apple seems to have much better hardware quality control than most vendors and iPhones might not ever have this issue.
