The 90hz mobile phone is smoother and clearer than the 60Hz mobile phone in image transformation, but if we only need to watch TV and brush microblog with the mobile phone, the 60Hz mobile phone is enough. But if you want to improve our sense of game experience, it is also a good choice to change a 90hz mobile phone.
60Hz and 90hz are generally used to refer to the refresh rate of the screen. The higher the refresh rate, the smoother the image on the mobile phone will be during transformation. In short, when we quickly move the perspective in the game, the higher the refresh rate, the clearer the picture displayed by the mobile phone.
60Hz is the configuration that most mobile phone screens can achieve now. For people who don't like playing games and only like to watch TV and brush microblog, 60Hz mobile phone is completely enough, and there is no need to blindly pursue 90hz mobile phone.
However, if we like playing games and have a keen observation on the refresh rate of the mobile phone screen, replacing a 90hz mobile phone can indeed better improve our game experience.
