Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a bypass continuation of International Application No. PCT/KR2023/002434, filed on Feb. 21, 2023, which is based on and claims priority to Korean Patent Application No. 10-2022-0032264, filed on Mar. 15, 2022, and Korean Patent Application No. 10-2022-0097350, filed on Aug. 4, 2022, in the Korean Intellectual Property Office, the disclosures of which are incorporated by reference herein in their entireties. BACKGROUND 1. Field Embodiments of the present disclosure relate to a method and an apparatus for maintaining performance (e.g., communication performance) of an electronic device in correspondence with an internal temperature of the electronic device. 2. Description of Related Art In accordance with development of digital technologies, various types of electronic devices, such as a personal digital assistant (PDA), an electronic notebook, a smartphone, a tablet personal computer (PC), a wearable device and/or a laptop PC, are widely used. These electronic devices have been continuously developed in terms of hardware and/or software of the electronic devices to support and increase functions thereof. Recently, an electronic device uses a sensor (e.g., a thermistor or a temperature sensor) capable of measuring a temperature inside the electronic device to monitor heat generation of the electronic device and provide information (e.g., heat generation information) related to the use of the electronic device, based on a monitoring result. According to an embodiment, an electronic device may include a sensor (e.g., a thermistor) mounted therein through an electronic component (or semiconductor) or an instrument (e.g., a circuit board) to design a semiconductor and measure a temperature of the corresponding electronic component. According to an embodiment, in the electronic device, the thermistor may be designed as a chip and may represent a semiconductor configured to measure (or detect) a temperature using a principle that resistance changes depending on temperature. According to an embodiment, the electronic device may apply a voltage to the thermistor, convert a value according to voltage distribution into an electrical signal, and determine a temperature using the electrical signal through a processor. Furthermore, various services are provided to electronic devices as a result of technology development and wireless network performance improvement. For example, recently, a positioning service using electronic devices has attracted attention. The positioning service may be a general term for identifying a location of user and providing various services based on the location. For example, conventional positioning services may include a location tracking service that tracks a location of a user by tracking a location of an electronic device through a global navigation satellite system (GNSS) and a geofencing service that determines entry or exit from a specific point-of-interest (POI). The GNSS may refer to a system configured to use a satellite and provide information on a location, altitude, and/or speed of an object on the ground. Recently, as electronic devices provide GNSS-based location function services, the importance of GNSS accuracy is emerging.
