What are the benefits of the 144 Hz screen? [iQOO Z1 Case]

We spend most of our time on our smartphones every day. We do everything through them. For this reason, we want a larger screen with smoother performance, a faster processor, more memory and storage, a more powerful camera, a longer lifespan, etc. I recently read an interesting article about the 144 Hz screen of the iQOO Z1. So I decided to tell you what I learned after a little research.

It's no secret that smartphones have triggered a revolutionary trend of high refresh rates. When we used to look at screen size, resolution, aspect and aspect ratio, we are now very concerned about whether smartphones are equipped with screens with a high refresh rate. One of the newest phones with a 144 Hz screen is the iQOO Z. So I decided to see if such a screen and especially this handset are as good as speaking. What is more important, I want to understand what the main advantages of such screens are?

Briefly About Screen Refresh Rate

Refresh Rate refers to the number of times the image is repeatedly scanned from top to bottom on the screen. The higher the refresh rate, the smoother the displayed image. Simply put, it's the same as when we read a book and turn a page. The image is made up of static images, and the refresh rate indicates how quickly we turn pages.

The same thing happens with the screen. However, the latter is displayed individually from top to bottom. More importantly, the entire page is updated frame by frame. We usually need at least 24 frames per second. However, most current smartphones support the refresh rate of 60 fps. It seems that no more frames need to be displayed at the same time. Why did some manufacturers choose higher refresh rates?

As I said, a higher refresh rate has more frames in the same period. The higher the frame rate, the fewer afterimages on the screen and the smoother the animation. The 60 Hz screen is updated 60 times per second, the 90 Hz screen is updated 90 times per second, and the 144 Hz screen is updated 144 times per second.

The reason why screens with high refresh rates are so popular is simple – cost and power consumption. It's no secret that screens in smartphones are the "hungriest eaters". The lower the energy consumption of the screen, the better. In other words, lower power consumption can extend battery life. These two restrictions are also the reasons why some smartphone manufacturers use screens with a high refresh rate.

This handset uses an LCD screen. The high refresh rate on the LCD screen can effectively solve the power consumption problem. In addition, this screen has passed the German Rhine eye protection certification. So we are dealing with an eye protection display.

The quality of the iQOO Z1 LCD screen itself is not bad, which makes the high refresh rate of 144 Hz useful.

The image above shows that the higher the screen refresh rate, the better the real-time dynamic image display.

The high refresh rate of 144 Hz is very intuitive for improving the smartphone experience. During the game, the higher refresh rate can make operations like aiming and changing scenes more chiral and rational with the help of chirality. The player's gaming experience can thus be improved considerably.


If you need a smartphone with a high refresh rate, especially 144 Hz, there are currently not many options. You can only purchase the Nubia Red Magic 5G, the iQOO Neo 3, the Nubia Play, the iQOO Z1 5G or wait for the Lenovo Legion. As you can see, two of them belong to Nubia and two to iQOO / Vivo. We talked about the iQOO Z1's screen, which is a "traditional" handset. However, it is not difficult to guess that 144 Hz screens mainly appear on gaming smartphones.

P.S. I chose the iQOO Z1 for several reasons to introduce the benefits of a 144 Hz screen. The most important thing is that it is operated with the MediaTek Dimensity 1000+ chip. As I know, this is the only non-Qualcomm chip that supports this function. The above models are mainly equipped with Snapdragon 865 or 765G. If this technology is to become increasingly popular, other chip manufacturers should also equip their processors with similar functions. Otherwise, Qualcomm will conquer the entire market again as soon as a high refresh rate becomes mainstream. Of course, things like that don't last long. But they bring many advantages to the “monopolists”. In this sense, the iQOO Z1 shows that the MediaTek chip could also compete.
