Abstract
After a mobile terminal recognizes a type of a power adapter, the mobile terminal transmits indication information to the power adapter. The indication information is configured to indicate that the mobile terminal has recognized the type of the power adapter and instruct the power adapter to activate a quick charging process. The power adapter then negotiates with the mobile terminal via the quick charging process to determine charging parameters, and charges a battery of the mobile terminal in a multi-stage constant current mode.
