Abstract: A technique for dynamically adjusting power use of an input/output (I/O) interface of an electronic device is provided. The electronic device includes an input/output (I/O) interface that facilitates electronic communications with a receiving electronic device, at a particular transmission rate that is dynamically changeable by the electronic device. Transmission power and transmission rate adjustment circuitry determines whether a step-down in a transmission power used for signal transmission at the particular transmission rate is desirable. When desirable, the transmission power is dynamically adjusted down one step, such that less power is used by the I/O interface during the electronic communications.
