How do I turn off wireless charging on my iPhone?

You can't. Just don't place your iPhone on a wireless charger.

When you remove your iPhone from the wireless charger, it should automatically power down into power reserve until you need it again.

Perhaps if you explain why you want to do that, someone can give you alternative suggestions.

when your iphone is fully charged it stops charging from the wireless charging pad
