ELI5: Why do phone chargers eventually get to a point where you have to place them in a very specific position to actually charge?

Copper is very expensive, so the manufacturers are making the wires thinner and thinner, and everytime you bend the cord it weakens the wire until the point it breaks.  If you bend a certain way you're still barely making contact.   Whatever you do, do not wrap your cord around the brick, keep it as loose as possible, or if possible have a charger for each location and dont keep messing with it.
