Patent attributes
A charging method and a mobile terminal are provided. The method includes setting an initial cut-off voltage and an initial charging current of a battery when the battery is subjected to constant current charging. The initial cut-off voltage is greater than a safe cut-off voltage of the battery. A battery voltage of the battery is detected. Whether a present value of the battery voltage is equal to the initial cut-off voltage is determined. The initial cut-off voltage and the initial charging current are gradually decreased when the present value of the battery voltage is equal to the initial cut-off voltage, until the initial cut-off voltage is less than or equal to the safe cut-off voltage, and then the battery is subjected to a constant voltage charging, where a voltage of the constant voltage charging is the safe cut-off voltage.
