Abstract: The method includes: a first electronic device detects signal strength existing when the first electronic device communicates with a second electronic device, and determines whether the signal strength is less than a preset value; when the signal strength is less than the preset value, the first electronic device determines a current service state of the second electronic device, and determines, based on the current service state, working modes that respectively correspond to the first electronic device and the second electronic device and that are suitable for the current service state; and the first electronic device switches a working mode to the determined working mode that corresponds to the first electronic device and that is suitable for the current service state, and sends an instruction to indicate the second electronic device to switch a working mode to the determined working mode that corresponds to the second electronic device.
