Abstract: “Charging geomagnetic interference resisting method executed by a mobile terminal is provided. The charging geomagnetic interference resisting method includes detecting, by the mobile terminal, a current charging state of the mobile terminal. When the current charging state includes the mobile terminal is being charged, voltage values of multiple preset sampling points are read. A maximum voltage difference value between the multiple preset sampling points are then acquired according to the voltage values of the multiple preset sampling points to obtain a corresponding voltage difference value. A corresponding magnetic field compensation value is also determined based on the voltage difference value. Then, a current magnetic field value of the mobile terminal is read, and the current magnetic field value and the magnetic field compensation are superimposed to acquire a corresponding actual magnetic field value.
