ROG Phone 2

Mobile gaming Asus ROG and Razer Phone 2 Phone 2 equipped with a number of features qualified, one of which is a screen with a refresh rate of up to 120 Hz (Hertz). High refresh rate screen specifications are also starting to be owned by various non-gaming smartphones, ranging from OnePlus 7 Pro, Real X2 Pro, to the Oppo Reno Ace, with the number 90 Hz.

So, what’s the difference between 90 Hz and 120 Hz screens? Then, do we really need a cellphone with a high refresh rate ? What is a refresh rate? Before diving further, let’s first discuss what exactly is meant by the refresh rate.

As the name suggests, the refresh rate is a specification on the panel component that measures how often a frame (picture) on the screen is updated ( refreshed ) every second. Simply put, a 60 Hz screen is capable of displaying 60 images every second, as well as a 90 Hz and 120 Hz screen, each capable of displaying images 90 and 120 frames per second.

In other words, the higher the refresh rate, the smoother the image displayed by the smartphone, because the image is displayed every second, even though it is not visible, there are more.

Refresh rate is not a frame rate Well, even though it sounds the same, the refresh rate itself is actually different from the frame rate or commonly called frames-per-second (fps) commonly found in video specifications. As mentioned earlier, refresh rate is an on-screen technology, while fps is a specification of the image or video displayed.

If a 120 fps video is played on a 60 Hz screen, the screen will actually adjust the video so it can be played in 60 fps mode . The difference is the case for a 120 Hz screen that can display 60 fps , 90 fps , up to 120 fps videos . Most smartphones today are equipped with panels with a standard refresh rate of 60 Hz.

The difference between 60 Hz, 90 Hz and 120 Hz screens can be felt when users try out all three screens with different smartphones simultaneously, then compare the speed of the image animation or the transition between menus on the three phones.

Effect on battery life

Although images displayed on smartphones are more enjoyable to look at and feel, screens that have high refresh rates also have disadvantages, especially on the power side. Because, the higher the refresh rate , the greater the power needed. Thus, cell phone battery life can also be affected.

Therefore, some vendors actually embed a setting where users can switch from high refresh rates to standards, for example from 120 Hz (if it supports) to 90 Hz or 60 Hz, to simply save battery power. Not only the battery, pinning the screen with a high refresh rate also costs not cheap, and makes smartphone prices expensive, as summarized from DigitalTrends, Wednesday (2/22/2020).

So, for now, the 120 Hz screen technology will most likely not be present in middle-class smartphones , let alone entry-level phones. Do you need a smartphone with a high refresh rate? After discussing a variety of things earlier, maybe it occurred to you, do we need a screen with a high refresh rate to pursue perfection on a smartphone?

The answer can be yes or no. If you are someone who likes to play various “heavy” games, such as PUBG Mobile , Call of Duty: Mobile , and the like, or someone who is devoted to the world of e-sports , it’s good to glance at mobile phones that are equipped with 120 Hz speed screens.

But if you use a smartphone for everyday purposes, for example to communicate, to facilitate work, to just watch videos, a smartphone with a standard refresh rate of 60 Hz would be suitable for marriage. In other words, everything comes back to your choice and don’t forget to adapt it to your individual needs.
