Disclosed are a TWS earphone, a method and apparatus for reducing earphone energy consumption, and a computer-readable storage medium. The method for reducing earphone energy consumption comprises: determining whether a target earphone is in an off-ear state and is not placed in a charging case; if so, acquiring a timekeeping duration since the target earphone is taken off of an ear; determining whether the timekeeping duration exceeds a first preset threshold value; and if the timekeeping duration exceeds the first preset threshold value, performing energy consumption reduction processing on the earphone. According to the present application, the duration since an earphone is taken off of an ear is evaluated for the earphone that is taken off of the ear and is not placed in a charging case, so as to perform energy consumption reduction processing on the earphone that has been taken off of the ear for a relatively long duration, such that unnecessary power consumption of the earphone when same is in a not-in-use state can be effectively reduced, and the effective service time of the earphone after charging is prolonged.
