The invention discloses a method for optimizing wireless charging stability, comprising a wireless charging base wirelessly connected to each other and a mobile phone equipment terminal. The mobile phone device terminal comprises a coil, a battery and a sensor unit. The sensor unit comprises a switch and a sensor assembly. The switch is used for communicating or disconnecting the circuit between the coil and the battery of the mobile phone device terminal. The sensor assembly is used for detecting the change value of the mobile phone device terminal in three directions of x, y and z in real time. The invention provides a method for optimizing wireless charging stability, which utilizes a plurality of sensor components of a mobile phone equipment terminal to optimize the stability of wireless charging, and does not charge when the mobile phone equipment terminal is in a mobile state, thereby ensuring the stability of wireless charging.
