I do not see “wireless charging “ in the assessability
trying to turn on wireless charging…
I went to General/assessability. I do not see an option for a “wireless charging”.
This is on my iPhone 11 Pro Max
There is nothing that needs to be turned on. The iPhone 11 Pro Max will automatically charge wirelessly when placed on a compatible Qi charging pad as shown the support document you posted from.
There is no setting for it in Accessibilty. Why were you looking for such a setting?
