Abstract
The present invention provides a method and an apparatus for power supply control as well as an electronic device. The method comprises: detecting that the first device is connected with the second device via the first physical interface, when the first device is in the unconnected state; determining whether the connection between the first and second devices satisfies a first predetermined condition or not, so as to obtain a first determination result; switching the first device from the unconnected state to the first connected state when the first determination result indicates that the connection satisfies the first predetermined condition; obtaining power supply requirement information of the second device that indicates whether the first device is required to supply power to the second device or not; and controlling the power supply to the second device via the first physical interface based on the power supply requirement information.
