This application disclose example electric energy control methods. When power of a main device is lower than baseline power, an energy storage device is in a charging state and stores remaining electric energy. When power of a main device is greater than the baseline power, the main device receives electric energy output by a power supply device and the energy storage device. To be specific, the energy storage device is in a discharging state and supplies power together with the power supply device to ensure operation of the main device. However, an amount of electric energy stored in the energy storage device is limited. When an amount of the electric energy of the energy storage device is insufficient, the main device is notified to decrease radio frequency power of a preset frequency band of the main device, to reduce a breakdown caused by excessively high power of the main device.
