Does Guanfudun affect the heat dissipation of mobile phones?

A: Guanfudun does not affect the heat dissipation of the mobile phone and can be ignored. Reason: ① Glass is a good conductor of heat (with a thermal conductivity of approximately 1W/m·K) and does not provide significant insulation. ② The film thickness is only 0.3mm, with extremely low thermal resistance. ③ The main heat dissipation paths for mobile phones are the middle frame and the back panel (especially the back panel at the processor position), and the screen is not the main heat dissipation surface. The influence of the film on the overall heat dissipation can be ignored. ④ The adhesive layer and AR coating of the film have a minimal impact on heat dissipation. The factors that may affect heat dissipation are: ① Inferior thick film (0.4mm or more) + multi-layer structure, with a slight impact but not obvious; ② The impact of phone cases on heat dissipation is much greater than that of films (plastic cases have obvious heat insulation, especially during gaming). If you play large-scale games while charging, the phone itself will heat up. This is the heat from the processor and battery, and has nothing to do with the film. Note: ① If your phone gets abnormally hot (scalding to the touch), it's not a problem with the film. It could be due to too many background apps, system bugs, aging battery or excessively high ambient temperature. It is recommended to investigate the cause. ② Do not use your mobile phone in high-temperature environments (such as when the car is exposed to direct sunlight in summer). No film can solve the problem of high temperatures. ③Guanfudun 0.3mm South Glass high alumina glass has good heat conduction, and gamers can use it with confidence.
