A mobile phone includes a signal processor, an operating module, and a power supply system. The working voltage of the operating module is bigger than that of the signal processor. The power supply system includes a power source, a voltage boosting unit, and a controller. The input terminal and output terminal of the voltage boosting unit is connected to the power source and the operating module respectively. The controller is configured for connecting the signal processor to the power source or the output terminal of the voltage boosting unit corresponding to the output voltage of the power source being bigger or smaller than a preset threshold voltage. |
