A method is provided comprising: detecting a connection between an electronic device and a battery charger; transmitting to the battery charger a first request for at least one of a first voltage level and a first current level; receiving from the battery charger a signal; and charging a battery of the electronic device with the signal.

Method and apparatus for charging a battery

A control circuit for reducing a charging time and a method thereof are provided. The charging device includes an input unit configured to receive a control signal indicating that applied power is process power, and a switch configured to cut off a path between a terminal set and a battery while the process power is applied, when the applied power is the process power.

Control circuit for reducing charging time and method thereof

A method and an apparatus for rapid charging in an electronic device are provided. In a method for charging a battery of an electronic device, an operation environment of the electronic device is determined. A charging current corresponding to the operation environment of the electronic device is set. Battery charging is started using the set charging current. The battery is charged using a maximum allowed charging current, such that a battery charging time may be reduced.
