Abstract
An electronic device includes a processor, a battery, a charging circuit, a controller, and an arithmetic logic unit. The processor is capable of operating at a preset frequency or a low frequency. The charging circuit is electrically connected to an external power supply and a battery and transmits a disconnection signal and to be powered by the battery when the external power supply and the charging circuit are changed from a connected state to a disconnected state. The controller is configured to transmit a first control signal when the external power supply and the charging circuit are changed from the connected state to the disconnected state. The arithmetic logic unit is configured to transmit a frequency reduction signal to the processor according to the disconnection signal and the first control signal, so that the processor reduces the preset frequency to the low frequency and operates at the low frequency.
