1. An operating method of an electronic device, the operating method comprising:
- providing power from a battery to an external device using a first circuit based on determining that the external device is connected to the electronic device through an USB connection;
receiving power from a first power source wirelessly connected to the electronic device;
providing the received power to the battery using a second circuit,determining whether a second power source is connected to the electronic device based upon determining that the external device is disconnected from the electronic device; and
providing power to the battery using the power supplied from the second power source using the first circuit based upon determining that the second power source is connected to the electronic device,wherein providing power to the battery using the first circuit and providing power to the battery using the second circuit are performed simultaneously,wherein providing power to the external device using the first circuit and providing received power to the battery using the second circuit are performed simultaneously.

6. An electronic device comprising:
-
a battery; a first circuit configured to provide power from the battery to an external device based on a determination that the external device is connected to the electronic device through an USB connection; and a second circuit configured to receive power from a first power source wirelessly connected to the electronic device, and provide the received power to the battery, wherein power being provided to the external device using the first circuit and received power being provided to the battery using the second circuit are performed simultaneously, wherein, based on a determination that the external device is disconnected from the electronic device and a second power source is connected to the electronic device, power is provided to the battery using power supplied from the second power source using the first circuit, wherein power being provided to the battery using the first circuit and power being provided to the battery using the second circuit are performed simultaneously. - View Dependent Claims (7, 8, 9, 10)
