IIRC its the other way round: your phone will not realize it is actually being plugged into a USB Type-A port, which might not be able to (safely) supply the current a USB 3 Type-C port potentially would allow. This is done by terminating a certain pin of the cable with a respective resistor, while USB Type A has no such pin and such a cable must thus by default terminate to 56kOhm. If now the cable does _not_ terminate, the phone might think it can draw way more power than the PCs slot can safely deliver, thus frying your PC port. The phone is not the problem.
