Abstract
In a charging method of adjusting charging current, an instant input voltage of a mobile terminal, an instant input current of the mobile terminal, an instant battery voltage, and instant system load current of the mobile terminal are acquired when a charging device charges the mobile terminal. An instant charging current is computed based on instant input power, instant system load power, and the instant battery voltage. The instant input power is defined as the multiplication of instant input current and the instant input voltage, and the instant system load power is defined as the multiplication of the instant battery voltage and the instant system load current. An instant input current increases when the instant battery voltage is less than a charging cut-off voltage and the instant charging current is less than preset current.
