With the development of mobile intelligent terminals (hereinafter referred to as "terminals"), terminal manufacturers and consumers have increasingly strict requirements for the user experience of terminals. While pursuing the diversity of terminal functions and smooth operation, the thickness of the terminal appearance is also becoming thinner and lighter. The complex requirements of use and the design of highly integrated electronic components have increased the burden on the terminal circuit board, and also increased the danger of high heat generation of the terminal. However, too high internal temperature will lead to degraded terminal performance and shortened hardware life, which will affect the user experience and even pose health and safety hazards.

In order to better evaluate the temperature control performance of the terminal in a more standardized manner, the China Academy of Information and Communications Technology (hereinafter referred to as the "CAICT") and the CTTL Certification Center Co., Ltd. (hereinafter referred to as "CTTL Certification") jointly formulated and released the "Technical Specification for Temperature Control Performance Certification of Mobile Intelligent Terminals" (hereinafter referred to as the "Technical Specification").

According to the technical specifications, after a comprehensive evaluation of the Galaxy S24 Ultra (SM-S9280) model mobile phone in the normal temperature charging state, room temperature non-charging state, high temperature non-charging state test environment WeChat video call, recorded video, online video playback, online music background playback and Internet browsing parallel, online game, online short video playback, online live broadcast and other seven scenarios, this model of mobile phone has reached the "mobile intelligent terminal temperature control high-performance certification" excellent level requirements, obtained"Mobile Intelligent Terminal Temperature Control High Performance Certification" excellent level certification.

Mobile Smart Terminal Temperature Control High Performance Certificate

In the future, the China Academy of Information and Communications Technology (CAICT) will continue to launch smart phone test solutions according to the development of industry technology, and update and iterate the test solutions, so as to provide the public with rich consumer references and suggestions with professional and fair test methods, and guide the healthy and sustainable development of the mobile phone industry.
