Description

[Technical Field] Embodiments of the present disclosure relate to an electronic device and a power supply method using the same. [Background Art] With the advancement of digital technology, various types of electronic devices such as mobile communication terminals, smartphones, tablet personal computers (PCs), personal digital assistants (PDAs), electronic notebooks, notebooks, wearable devices, Internet of Things (IoT) devices, and/or audible devices are widely used. Electronic devices are moving away from uniform rectangular shapes and gradually evolving into diverse forms. For example, electronic devices are increasingly developing into wearable electronic devices (e.g., wireless earphones) that can be worn on parts of the human body to enhance portability or user accessibility. The above information may be provided as related art for the purpose of assisting in understanding the present disclosure. No claim or determination is made as to whether any of the above is applicable as prior art related to the present disclosure. [Disclosure of Invention] [Technical Field] Electronic devices (e.g., wearable electronic devices, wireless earphones) are manufactured in a miniaturized form to facilitate carrying or wearing on a part of the body and may be designed with a battery included within the internal space of the electronic device. For example, the electronic devices may be implemented in a form where the battery is physically difficult to separate. After the manufacturing is completed, electronic devices may remain in a state in which power is continuously supplied on the basis of the built-in battery. In manufactured electronic devices, power is continuously supplied, at least partially, to the internal circuit via the battery, which may lead to the problem of battery performance degradation. Manufactured electronic devices may undergo distribution processes lasting several days to hundreds of days before reaching consumers, during which battery performance may gradually degrade. For example, as batteries continuously discharge, their available capacity (e.g., maximum charge capacity, battery capacity) may decrease at least partially. Electronic devices with degraded battery performance may experience relatively low voltage supply during operation. Under low voltage supply conditions, the battery may also exhibit swelling phenomena. Particularly for miniaturized batteries, a decrease in battery capacity may lead to relatively greater performance degradation compared to larger batteries. According to one embodiment, during the distribution process of manufactured electronic devices, battery performance degradation may occur because of continuous battery consumption. According to one embodiment, the objective is to provide an electronic device that prevents battery performance degradation during the distribution process of manufactured electronic devices. The technical subjects pursued in this document may not be limited to the above mentioned technical subjects, and other technical subjects which are not mentioned may be clearly understood, through the following descriptions, by those skilled in the art to which this document pertains. [Solution to Problem] According to various embodiments, an electronic device may comprise: a sensor module for detecting, while mounted on a charging device, the state of a charging device; a communication module; a memory; and a processor operatively connected to the sensor module, the communication module, and the memory. The processor can: check a closed state of the charging device by using the sensor module; start a low power process in response to the closed state being maintained for the set time; check whether information related to pairing with at least one external electronic device is present in the memory; block power supply using the charging device if the pairing-related information is not present in the memory; and enter a first low power mode in which power is not supplied to an internal circuit of the electronic device. In a method for supplying power to an electronic device according to various embodiments, the method may comprise: checking a closed state of the charging device by using the sensor module while mounted on a charging device; starting a low power process in response to the closed state being maintained for the set time; checking whether information related to pairing with at least one external electronic device is present in the memory; blocking power supply using the charging device if the pairing-related information is not present in the memory; and enter a first low power mode in which power is not supplied to an internal circuit of the electronic device. [Advantageous Effects of Invention] According to various embodiments of the present invention, an electronic device (e.g., a wearable electronic device, a wireless earphone) that has been manufactured may detect a situation where the electronic device will not be used for a certain period
