Gaming is invading the mobile ecosystem more and more frequently, and this causes features that were previously only sought in environments such as the PC also appear on our pocket computers. One of the most wanted, according to the effort of manufacturers to promote it, is that of increasing the frequency, speed or refresh rate of the screen.

Accustomed as we were to the fact that in the mobile there were only a couple of characteristics or three that separated some screens from others (panel technology, diagonal, resolution), now we also face the hertz. This 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 phone.

What is the refresh rate


It is convenient to explain, even if briefly, how any screen works, also that of a mobile phone. Although we see it permanently on during the time we are using it, the screen is constantly turning off and on. The screen displays one image, turns off, displays another image, and turns off. So constantly.

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

Until recently, 100% of mobile screens had 60 hertz. This means that these displays turned on and off 60 times per second. 60 on and 60 off to refresh the image that was shown in it. So this feature is 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 identical when we see something static.

This is, no more and no less, the refresh rate of a screen, whether mobile, personal computer or television. And once we have more or less clear the concept, it is time to explain how it benefits us to have higher refresh rates on our mobile phone. Although it also has its drawbacks, of course.

The advantages and disadvantages of increasing the refresh rate


As we’ve explained before, the screen refresh rate works similarly to frames per second, so we have the same advantages and disadvantages. That is the higher the hertz number on our screen, the more fluid the movement will be appreciated in it, although we will need help from the mobile processor for the experience to be complete.

If our screen is 60Hz and our mobile runs games at 60 frames per second, we will see a new frame 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 images in 90 turns. Maths. Hence gaming mobile phones arrive ready to show higher bit rates, 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

This is something that should go smoothly but developers have to adjust their games so that they run at higher speeds, hence from time to time there are announcements from the big developers about this or that game that now “supports 90Hz screens” or “supports 120Hz screens”. That is, the developers have released their code execution for higher speeds and can now run at 90 and 120 frames per second, matching the screens.

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

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


Typically, the manufacturer itself has been responsible for making it clear to us what the refresh rate of our mobile screen is, and that if this has not been the case, it is because the screen is 60Hz. That is, it is like that of the rest of mobiles until just under two years ago, and not all models have taken a step forward. However, there is a way to find out the hertz of our mobile screen if we don’t know or have forgotten them.

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

With DevCheck we can check all the hardware features of our mobile phone, a useful process if we want to know if we have bought, for example, a fake mobile or an authentic one, since it brings to light all the real characteristics of the phone. But there is one that interests us especially in this article and that is the frequency of refreshment.

Just open DevCheck once installed and go to the “Hardware” tab. In it, the information of the processor is shown first and just after that we have the information of the graphics. Just before reaching the “Memory” section we have a section called “Frame Rate “, and here the hertz are shown. Typically, we move between four figures (according to today’s mobiles): 60Hz, 90Hz, 120Hz or 144Hz. Done, that’s the refresh rate of our mobile screen.

Finally, if you are looking to squeeze the graphic section of a mobile phone, you may be interested to know which ones, at least until now, have sought to exploit this section.
