Abstract: This application discloses a charging cable-based data transmission method and an electronic device. A first electronic device is connected to a second electronic device through a third electronic device, and the third electronic device includes a first data signal line and a second data signal line. When the method is applied to the first electronic device, the first electronic device may detect a connection to the second electronic device; send a first message through a first pin, where the first pin is connected to the first data signal line; and receive a second message through a second pin, where the second pin is connected to the second data signal line, and the first message and the second message are used for charging setting of the first electronic device.
