CPC H02J 50/12 (2016.02) [H02J 7/02 (2013.01); H02J 50/80 (2016.02); H02J 50/90 (2016.02)] | 6 Claims |
1. An electronic device comprising:
a housing including a first plate, a second plate spaced apart from the first plate and a side member disposed between the first plate and the second plate;
a display disposed under the first plate;
a conductive coil disposed between the display and the second plate;
a wireless charging circuitry electrically connected to the conductive coil; and
a processor operatively connected with the display and the wireless charging circuitry, wherein the wireless charging circuitry configured to:
transmit, via the conductive coil, a charging power to an external electronic device based at least in part on a power control signal being received from the external electronic device;
increase a charging frequency corresponding to the charging power based at least in part on a determination that the power control signal includes a request to reduce the charging power; and
if the charging frequency corresponding to the charging power reaches a specified frequency, maintain the charging frequency to be the specified frequency and decrease a duty cycle corresponding to the charging power.
