Battery charging method and electronic device
A method comprises providing power from a battery to an external device using a first circuit; and receiving power from a first power source to provide power to the battery using a second circuit while providing power to the external device.
1. A method of operating an electronic device, the method comprising:
detecting occurrence of a wireless charging event for wirelessly receiving first power;
charging a battery of the electronic device using the first power, based on detecting the occurrence of the wireless charging event;
detecting, in a state of charging the battery using the first power, occurrence of a wired charging event for receiving second power via a wired connection;
identifying first information associated with a first charge capacity of the first power and second information associated with a second charge capacity of the second power;
identifying, based on the first and second information, which one of the first power and the second power has a higher charge capacity; and
selecting the first power or the second power having the higher charge capacity for charging the battery.
2. The method according to claim 1 , wherein the electronic device comprises a mobile telephone or a tablet computer.
3. The method according to claim 1 , wherein the electronic device and the external electronic device comprise respective mobile telephones.
4. The method according to claim 1 , further comprising:
displaying, on a display screen of the electronic device, a notification notifying that the first power is being supplied to the external electronic device.
5. The method according to claim 1 , wherein the wired connection is a Universal Serial Bus (USB) connection.
6. The method according to claim 5 , wherein the USB connection comprises a USB On-The-Go (OTG) connection.
7. The method according to claim 6 , further comprising:
displaying, on a display screen of the electronic device, an operation state of the USB OTG connection.
8. The method according to claim 1 , wherein detecting the occurrence of the wireless charging event comprises detecting an induced current.
9. An electronic device comprising:
a battery; and
circuitry configured to:
detect occurrence of a wireless charging event for wirelessly receiving first power;
control charging of the battery using the first power, based on detecting the occurrence of the wireless charging event;
detect, in a state of charging the battery using the first power, occurrence of a wired charging event for receiving second power via a wired connection;
identify first information associated with a first charge capacity of the first power and second information associated with a second charge capacity of the second power;
identify, based on the first and second information, which one of the first power and the second power has a higher charge capacity; and
control selecting the first power or the second power having the higher charge capacity for charging the battery.
10. The electronic device according to claim 9 , comprising a mobile phone or a tablet computer.
11. The electronic device according to claim 9 , wherein the circuitry is further configured to control displaying, on a display screen of the electronic device, of a notification notifying that the first power is being supplied to the external electronic device.
12. The electronic device according to claim 9 , wherein the wired connection comprises a Universal Serial Bus (USB) connection.
13. The electronic device according to claim 12 , wherein the USB connection comprises a USB On-The-Go (OTG) connection.
14. The electronic device according to claim 9 , wherein the circuitry is further configured to control display, on a display screen of the electronic device, of an operation state of the USB OTG connection.
