Abstract

The invention provides a charging method and a mobile terminal, and relates to the technical field of mobile terminals. The method comprises the following steps: detecting the temperature at a charging interface of the mobile terminal, judging whether the temperature at the charging interface is greater than a temperature threshold or not, and sending an adjustment signal to a charger when the temperature at the charging interface is greater than the temperature threshold so as to enable the charger to adjust the output charging current. By detecting the temperature at the charging interface and judging whether the temperature at the charging interface is greater than a temperature threshold or not, when the temperature at the charging interface is greater than the temperature threshold, the adjustment signal is sent to the charger, so that the charger can adjust the output charging current, the charging current is further controlled to decrease, and a great deal of heat is avoided being continuously generated at the charging interface; therefore, the temperature at the charging interface can be reduced in time, the safety problem caused by the overhigh temperature at the charginginterface can be avoided, and the charging safety of the mobile terminal is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of mobile terminals, and in particular, to a charging method and a mobile terminal. Background technique [0002] With the continuous development of mobile terminals and the emergence of graphene batteries, mobile terminals can be charged with large currents through graphene, thereby greatly shortening the charging time and improving the charging efficiency of mobile terminals. [0003] In the related art, after the charger is connected to the charging interface of the mobile terminal, the charger can use a large current to charge the graphene battery. However, when there are foreign objects inside the charging interface of the mobile terminal, or when the charging interface is deformed, the impedance between the charging interface and the charger will increase. If a large current is still used for charging, the temperature of the charging interface will be too high. There is a safety ...
