Screen refresh rate is an add-on that is very difficult to use in marketing, because in fact the benefits of this feature users can only realize when they will be using the phone with it their hands. 90Hz screen refreshing is becoming increasingly popular on the market. Initially, this function was often added to smartphones dedicated to players, and recently a lot of favorable reviews for the implementation of such a solution for their devices received OnePlus company. Other manufacturers are likely to follow this lead, and one of them even wants to break OnePlus' achievement.
Recent reports indicate that Xiaomi is thinking of creating a phone whose screen would use a 120Hz refresh rate. This is evidenced by the information found in the MIUI 11 code, where users found a special mention about changing the screen refresh mode. Certainly it would be an interesting move from the Chinese manufacturer, but from the user's point of view the difference between 90Hz and 120Hz is relatively difficult to catch by the human eye. It should certainly be enjoyed that slowly 90Hz refresh screen is becoming a standard on mobile market.
