I did buy the special Anker lightning cable needed to make recent Canon bodies support the iOS connection mode last weekLightning cables are now passé thanks to the EU! Wireless charging is indeed only about 70% efficient. I use plug in for charging but when out and about and there is a chance power might run out, it is more convenient to magsafe a wireless charger to the back of the iPhone and continue to hold the phone for calls or general use. There are some very nice little USB_C chargers like the Anker Nano Bank but I suppose it's not as robustly attached as by the magnets in the magsafe.
