An electronic device is provided. The electronic device includes a housing including a front plate that faces a first direction and a rear plate that faces a second direction, which is opposite the first direction, a display panel configured to output a screen through the front plate, a bracket disposed between the display panel and the rear plate, the bracket being configured to support internal components, a flexible printed circuit board including a first area electrically connected to the display panel, and a second area extending from the first area and disposed between the display panel and the bracket, a wireless charging structure disposed on one face of the second area or inside the second area, the wireless charging structure including a coil portion and transmission wires electrically connected to the coil portion, and a magnetic plate disposed between the bracket and the flexible printed circuit board, and at least one area of the magnetic plate being disposed to face the wireless charging structure.

Electronic device including wireless charging structure

According to various embodiments of the present invention, an electronic device comprises: a housing which comprises a first plate, a second plate facing the opposite direction from the first plate and a lateral member surrounding a space between the first plate and second plate; a hole which is formed through the lateral member and is connected to the space; a stylus pen which can be inserted to the space through the hole, wherein the stylus pen comprises a pen housing extending long between a first end part and a second end part and a first coil positioned inside the pen housing, wound about the axis in a first direction extending from the first end part to the second end part and having the coil length of a first length; a second coil which is disposed inside the space of the housing so as to partly face the first coil of the stylus pen when the stylus pen is fully inserted to the housing, wherein the second coil comprises a conductive wire extending over a first area facing the first coil and a second area not facing the first coil, wherein the conductive wire has a first width in the first area and a second width, which is smaller than the first width, in the second area; and a charging circuit which is electrically connected to the second coil. Other various embodiments other than the various embodiments disclosed in the present invention are possible.

Electronic device and stylus pen charging method using same

The disclosure relates to a method for providing hardware reset in an electronic device having at least one non-physical key and the electronic device thereof, and an operating method of the electronic device may include detecting a current amount supplied to a processor, detecting whether wireless power is input, generating a hardware reset signal based on the detected current amount and the wireless power input, and transmitting the generated hardware reset signal to the processor.

Hardware reset control method and electronic device

The present disclosure relates to a method and an electronic device for detecting a battery swelling. The device may include: a housing including a front plate, and a back plate facing away from and spaced from the front plate; a battery including a first surface facing the front plate and a second surface facing the back plate; a first layer including a conductive pattern parallel to the back plate, wherein at least a portion of the conductive pattern is interposed between the second surface of the battery and the back plate and a circuit electrically connected to a first point and a second point of the conductive pattern, and configured to transmit a signal to the first point and receive the signal from the second point; and further configured to: detect a phase difference between the transmitted signal and the received signal, and determine whether the battery is swollen based on the phase difference. The present disclosure may further include various other embodiments.
