Gaming is invading the mobile ecosystem with increasing frequency, so features that were previously only sought after in environments such as the PC are also appearing on our handhelds. One of the most sought after, according to the efforts of industrialists to promote it, is that of increase in frequency, speed or refresh rate of the screen.

As we were used to the fact that in mobile there were only a few features or three that separated some screens from others (panel technology, diagonal, resolution), now we also face the hertz. Now is a good time, why not, to try to explain what they really are, how they affect our screen and how we find out how many we have on board our mobile phones.

What is the refresh rate

It is convenient to explain, even briefly, the operation of a screen, also that of a cell phone. Although we see it constantly during the time we use it, the screen turns off and lights up constantly. The screen displays an image, turns off, displays another image and turns off. So constantly.

It is our eye that makes sure that we do not notice these blackouts due to the phenomenon known as “retinal persistence”, the same that causes us to bridge the gaps between frames so that we feel a real animation from. of photographs. And since hertz is a measure of frequency, when we talk about screen hertz we are talking about the times when a screen turns on and off per second.

  Not all Take Two games will experience a price increase, although the company continues to defend it.

Until recently, 100% of mobile screens had 60 hertz. This means that these screens are turned on and off 60 times per second. 60 on and 60 off to refresh the image displayed there. This feature is therefore known as the refresh rate. The screen turns on and off to change the image that shows us when there is movement, or to keep it the same when you see something static.

It is, no more and no less, the refresh rate of a screen, whether it is mobile, personal computer or television. And once the concept is more or less clear, it’s time to explain how we benefit from having higher refresh rates on our cell phone. Although it also has its drawbacks, of course.

The pros and cons of increasing the refresh rate


As we explained earlier, the screen refresh rate works similar to frames per second, so we have the same pros and cons. This is the higher the hertz number on our screen, the smoother the movement will be but we will need the help of the mobile processor to make the experience complete.

If our screen is at 60 Hz and our mobile is playing games at 60 frames per second, we will see a new image every time the screen is turned off and back on. If our refresh rate is higher, sometimes it will show us repeated frames to be able to distribute those 60 frames in 90 rounds. Matematics. Therefore gaming cell phones are coming ready to show higher bitrates, more frames per second.

A greater number of hertz, and therefore a higher refresh rate, we will have more fluidity at the cost of greater energy consumption

It’s something that should be fine but developers need to adjust their games to run at higher speeds, hence the occasional announcements from major developers about a particular game that now “supports 90Hz screens” or “supports 120Hz screens”. That is, the developers released their code execution for higher speeds and can now run at 90 and 120 fps, corresponding to screens.

Thus, the higher the refresh rate or frequency, the more fluid we will perceive with our eyes. On the negative side, displays with higher refresh rates consume more power than the slower for a logical reason. They light up more times per second. Although, to compensate a little, these ignitions are shorter, so the increase is not directly proportional. A 120 Hz display does not consume twice as much power as a 60 Hz display, but it does consume more. Positive and negative parts.

How do I know how many hertz my mobile screen has?


Typically, the manufacturer itself has been responsible for letting us understand what the refresh rate of our mobile screen is, and if it hasn’t, it’s because the screen is at 60 Hz. In other words, it is like that of the rest of the mobiles until a little less than two years ago, and not all models have taken a step forward. However, there is a way to know the hertz of our mobile screen if we do not know them or if we have forgotten them.

In the Google Play Store there are different apps that can show us this data, but here we are going to go to one, one of great confidence. This application is none other than DevCheck, and can be found on Google Play for free, although we have advertising inside.

With DevCheck we can verify all the hardware features of our mobile phone, a useful process if we want to know if we bought, for example, a fake mobile or a genuine one, as it highlights all the real characteristics of the phone. But there is one that interests us most in this article and that is the refresh rate.

Simply open DevCheck once installed and navigate to the “Hardware” tab. In it, the processor information is shown first and right after we have the graphics information. Just before we reach the “Memory” section, we have a section called ” Frame rate ” , and here the hertz are displayed. As a general rule, we move between four digits (depending on today’s mobiles): 60 Hz, 90 Hz, 120 Hz or 144 Hz. It’s done, that’s the refresh rate of our mobile screen.
