Sorry, to be clear my concern is that if I go with the full-size iPhone 12 then I'll want to use a pop-socket, but it will block the area that MagSafe attaches. Maybe the smaller size and lighter weight will make a difference. Really wish I could get a hands-on before pre-orders
Pop socket is making a MagSafe compatible one that you can snap on and off. That's probably your best way to continue to use them on the new phones.
