A few years ago, we lived so happily with 60 Hz refresh screens. Everything seemed fluid, fast and more than enough to us. Although this changed with the arrival of the 120 Hz panels and, once you try them, there is no turning back. Personally I have the iPhone 15 Proone of whose main virtues is its ProMotion display at 120Hz. With the use I give it, I want to answer the question with which I titled this post and know if 120 Hz is really worth it or if this figure is just marketing. The truth is that, a priori, the answer is clear: once you try a screen of this type, if you pick up an old phone, it will seem slow. The price could vary. We earn commission from these links What happens when you launch a mobile phone with 120 Hz? In the case of my iPhone 15 Pro (or any other mobile phone that has a 120 Hz refresh rate screen), the truth is that the best way to explain it to you what does it feel like with this figure It is not looking at the screen of this mobile phone, but any other screen that has a lower refresh rate. When you use your phone for the first time, you will notice a certain elasticity and that everything floats on the mobile and the animations on iOS will seem liquid to you. Although the clicking will come when you pick up a standard iPhone 15 or another mobile with 60 Hz. Suddenly, you will have the feeling that everything is jerking and there is a kind of delay on the screen and that it does not respond. Although, in reality, it’s not that that phone is slow, it’s that your brain has already become accustomed to the fluidity of twice as many images per second. Although another key concept that should be taken into account is the touch sampling. We often confuse fluency with response, but they are not the same. 120 Hz is responsible for visual latency (making movement look smooth), although touch sampling (240 Hz or more) is also important, since it is the speed at which the mobile screen reacts to your fingers. If the sampling is high, the time from when you touch the button until the action is completed on the mobile panel is drastically reduced. Here, it’s important to know that you can have a screen that looks cinematic (120 Hz), but if the sampling is low, you will notice that the control is heavy or slow. The fear I had was the battery consumption I have always thought that having such a fast screen was going to eat up my battery, but this is not the case. The secret to my iPhone 15 Pro (and any modern LTPO panel) is that its refresh rate is adaptive. This means that the phone manages intelligently, using the necessary refresh rate depending on what you are doing with the phone, so the battery does not drain faster thanks to this management. But, What does LTPO mean? These are the acronyms for Low Temperature Polycrystalline Oxide (in Spanish, Low Temperature Polycrystalline Oxide) and are responsible for making the screen “smart.” This is the technology that allows the screen to be dynamic and without it, the panel could not go down to 1 Hz when the image is fixed (something that saves battery drastically). Although the important thing is that the LTPO does not jump from minimum to maximum; It works like a ladder with many rungs. Depending on whether you watch a movie (24 or 48 Hz), scroll (80 Hz) or play a game (120 Hz), the panel chooses the exact step. Of course, this is a quality standard that we no longer see only in Apple, but also in the high-end from Samsung or Googleallowing the screens to always be on (Always-on Display) without sacrificing autonomy. The two scenarios in which I have noticed the 120 Hz refresh rate on my mobile It’s not that I’m a mobile gamer or that I make excessive use of photo and video editing, but that I use my iPhone for daily tasks such as see social networkscheck email, send messages WhatsApptake photos and also for some photo retouching. Looking at my use, there are two main advantages that I see to the ProMotion screen and they are these: Scrolling in social networks and web browsing: You will see that the screen flies at 120 Hz and even the text is readable while moving. On the other hand, if you have a mobile phone with a 60 Hz screen, you will see that the scroll On the screen it is slower, not exasperating, but noticeably the mobile screen goes much slower. Series and movies: Watching movies or series on your mobile is another scenario in which ProMotion screen makes the difference. Although on Android, the screen usually translates the fps into Hz (the figure being the same), on iOS it is different, since the LTPO screen of the iPhone 15 Pro adapts its refresh rate to multiples of the framerate. That is, on iPhone, the screen flashes 48 times to show 24 photos. Everything fits perfectly and looks stable. Although yes, sometimes you can notice micro jerks, but this is something unrelated to the screen, since it has to do with apps like YouTube or Netflix, which sometimes do not know how to “talk” well with the iPhone system and send photos at the wrong time. Is it worth investing in a smartphone with an adaptive refresh rate? If you come from a basic mobile phone and make the jump (like me) to an iPhone Pro or any other mobile phone with adaptive hertz, the investment is justified. It is true that It’s a silent improvement.but once your eyes get used to this type of screen, going back will be difficult and when you have a mobile phone with 60 Hz in … Read more
