Abstract: An electronic device according to an embodiment of the disclosure may include: a battery including an anode having a first length and a cathode having a second length different from the first length, a flexible printed circuit board electrically connected to the battery and surrounding at least part of a side surface of the battery, and a speaker stacked with the battery. The flexible printed circuit board may include a power wiring electrically connected to the anode and a ground wiring electrically connected to the cathode. A first current of a first winding direction generated due to a length difference between the cathode and the anode may flow in the battery, and a second current of a second winding direction opposite to the first winding direction may flow in a wiring disposed closer to the speaker between the power wiring and the ground wiring.

Abstract: An example electronic device includes a temperature sensor, a battery, a communication circuit, a connecting terminal, a processor, and a memory. The memory stores instructions which, when executed, cause the processor to control the electronic device to determine whether the connecting terminal is electrically connected with the external electronic device, measure a first temperature around the electronic device, receive first battery state information from the external electronic device, based on the measured first temperature being greater than a specified temperature, determine a first charging state of the battery of the external electronic device, and transmit a first signal for controlling the charging state of the battery of the external electronic device to be less than a first specified level, based on determining that the first charging state of the battery of the external electronic device is greater than or equal to the first specified level.
