Does a phone screen protector affect the heat dissipation of a phone?

A: The impact of tempered film on the heat dissipation of mobile phones is very small 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, while the screen is not the primary heat dissipation surface. The influence of the adhesive layer of the film and the AR coating on heat dissipation can be ignored. 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 are worried about heat dissipation, instead of worrying about the film, it's better to choose a light, thin and breathable phone case. The thickness of Woowhead Guanfudun is approximately 0.3mm. The glass substrate has good heat conduction and does not affect heat dissipation. Even for heavy gamers, the film will not become a bottleneck for heat dissipation. One piece per pack costs 129 yuan. You can use it with confidence.
