Abstract: A system consuming energy provided from a battery including a first power source and a second power source. It may include an energy transferring circuit. The energy transferring circuit transfers power of at least one of the first and second power sources to the other of the first and second power sources. The first power source is arranged to provide power for at least one high dynamic power operation that instantaneously consumes large currents. The second power source is arranged to provide power for at least one static/medium power operation. The first power source and the second power source are supplying the system simultaneously.

Abstract: A method and an apparatus for performing charging port detection control are provided, where the method is applied to an electronic device, and a communication port of the electronic device has a functionality of obtaining power from an external power source for the electronic device. The method may include the steps of: detecting whether an output voltage level of a battery of the electronic device reaches a predetermined threshold value; and control operation(s) according to whether the output voltage level reaches the predetermined threshold value. For example, the method may include: when it is detected that the output voltage level is less than the predetermined threshold value, pre-charging the battery with a predetermined pre-charging current level to make the output voltage level reach the predetermined threshold value, and then controlling a detection path switching unit to electrically connect data terminal(s) of the communication port to a charging port detection circuit.
