I did a poll on this exact topic in this sub the other day: https://www.reddit.com/r/iphone/comments/109j2rv/how_do_you_most_often_charge_your_iphone/?utm_source=share&utm_medium=ios_app&utm_name=iossmf

Conclusion: Yes, people do continue to use the charging port — more so than not.

Wireless charging has taken a chunk of users, though. MagSafe seems to be the primary wireless charging option for iPhone users in this sub — which is a decent first ‘win’ for MagSafe in iPhones. Still a ways to go to catch the traditional lightning cable, though.
