Method and device for testing matching degree between mobile terminal and charger

The invention belongs to the technical field of a mobile terminal, and discloses a method and a device for testing matching degree between a mobile terminal and a charger. The method comprises the steps of detecting electric quantity of the mobile terminal and charging data of the charger when the charger is connected with the mobile terminal; comparing the charging data of the charger with standard charging data which are recorded by the mobile terminal on condition of same electric quantity, if the charging data of the charger satisfies a preset condition, calculating a difference value between the charging data of the charger and the standard charging data, and otherwise, stopping charging and performing complete reminding; and outputting a difference between the charging data of the charger and the standard charging data. The method can accurately obtain the difference between charging the mobile terminal through the current charger and charging the mobile terminal through an original charger, thereby better guiding selection of the charger by the user.
