The invention discloses a method and apparatus for protect charging overheat. The method comprises the following steps: when a mobile terminal runs high power consumption application, detecting whether a charger insertion trigger signal is received or not; After receiving the charger insertion trigger signal, the charging chip is controlled to interrupt the input of the charging signal to the battery and the charging chip is controlled to input the power supply signal to the main board. Or, detecting whether the mobile terminal runs high power consumption application when the mobile terminalis connected with the charger; After the mobile terminal runs the high power consumption application, the charging chip is controlled to interrupt the input of the charging signal to the battery and the charging chip is controlled to input the power supply signal to the motherboard. The invention effectively prevents the problem of overheating of the battery and the motherboard, prevents potentialsafety hazards in the char
