Abstract

The application discloses a mobile terminal and a charging method thereof, belonging to the technical field of communication. When the processor in the mobile terminal provided by this application determines that the surface temperature of the secondary battery is greater than the surface temperature threshold and the secondary battery is in the state of charging the main battery, it can reduce the discharge current of the secondary battery and / or reduce the charging of the main battery. current to reduce the surface temperature of the sub-battery. Therefore, it is possible to avoid the problem that the secondary battery's use safety is lower due to the continuous rise of the surface temperature of the secondary battery, thereby ensuring the safety of the secondary battery in use.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a mobile terminal and a charging method thereof. Background technique [0002] Currently, a mobile terminal may include a main battery and a secondary battery. The main battery is fixed in the main body of the mobile terminal, and the secondary battery is detachably connected to the main body of the mobile terminal. The secondary battery is also called a back clip battery. When the secondary battery is connected with the main body, the secondary battery can charge the main battery of the mobile terminal. [0003] However, when the secondary battery is charging the main battery, the temperature of the secondary battery will increase due to the continuous discharge of the secondary battery. If the temperature of the secondary battery exceeds the temperature threshold, the use safety of the secondary battery will be low. Contents of the invention [0004] Em...
