PURPOSE: An electronic device and a method of managing power of the same are provided to reduce power consumption while a communication channel between the electronic device and an external device is an active state, by reducing or disabling power or a clock signal of a function block processing data transmission. CONSTITUTION: A universal serial bus (USB) controller (UCTL) transmits or receives data from or to an external electronic device via communications. When the USB controller is in an active mode, a USB power managing unit (UPMU) manages power of the USB controller in response to a state signal including state information that indicates whether data is being received at the USB controller or transmitted from the USB controller. If the state signal indicates that data is being received at the USB controller, the USB power managing unit generates a power control signal to reduce or disable power or a clock signal of a functional block of the USB controller utilized for transmitting the data.
