In this case, the problem is not how much power the computer "feeds" to the phone, the problem is how much amperage the phone draws from the computer. The bad Type-C cable can be incorrectly configured to indicate to the phone that the Type-A computer end can provide more amps than it actually can, and then the phone will provide less effective resistance across the 5v power wires than is appropriate.
