Copper is primarily used in cell phones in the circuitry. Copper wires, traces, and antennas are used to connect various components and allow them to communicate with each other. Copper is also used in some battery designs, but it is less common than other materials such as lithium-ion. Copper is not typically used in cell phone displays, nor in speakers.
