1. A method for automatic wireless charging alignment comprising:

  • calculating a wireless power transfer efficiency during a wireless charging session involving a wireless charging assembly having a transmitting coil and an electronic device having a receiving coil mounted to a linear actuator mechanism;

    controlling the linear actuator mechanism to move the receiving coil in a lateral direction such that the wireless power transfer efficiency increases;

    determining whether to move the receiving coil in a first lateral direction or a second lateral direction opposite the first lateral direction; and

    controlling the linear actuator mechanism to move the receiving coil in a lateral direction determined in the determining.
