Of course it does. The iPhone12 wireless charge has nothing to do with the phone case. This is basically unrelated to the phone case, because wireless charging, it is through the internal parts of the phone and the outside of the wireless charger to be paired and contacted before the normal charging of the phone. It is the internal reason of the mobile phone, so it has nothing to do with the mobile phone shell itself, and the mobile phone shell itself does not have any charging function.
Yes, but only if the phone case supports wireless charging
