The invention discloses a breathing light control method. The breathing light control method is applied to a smart device. The method comprises the steps of determining a working scene of breathing lights when it is detected that the smart device is powered on; determining a working breathing light and a working mode corresponding to the working breathing light according to the working scene of the breathing lights; and controlling the working breathing light to work according to the working mode corresponding to the working breathing light. The invention also discloses the smart device and acomputer readable memory medium. According to the method, the smart device and the computer readable memory medium, different light effects can be constructed through utilization of the breathing lights, thereby responding to application scenes of the smart device; the breathing lights have relatively high practicability; the sense of science and technology is improved; the relatively good visionexperience is provided for a user; and the interaction with a user can be realized.
