There’s a new fashion trend in the smartphone industry – high refresh rate displays! Razer started it all with its Razer phone back in 2017 and since then, the high refresh rate craze has conquered the tech world by a storm.

Now every self-respecting smartphone manufacturer has a high refresh rate model in its portfolio and this feature seems to be shaping users’ buying habits nowadays. Major phone brands have already adopted 120Hz displays – Apple, Samsung, OnePlus, Sony, and Google all have a flagship with a super-fast display, but is it really that important? Let’s find out!

Your smartphone display is made from tiny pixels that display different information – a certain color or a grayscale hue. The refresh rate is actually how many times per second a pixel can change the information it’s displaying.

With each cycle, new information is fed to the pixel and it “refreshes”. Conventional smartphone displays are able to change their display information 60 times per second, and we designate it as 60Hz (Hertz is a measurement for frequency – 1 hertz equals one cycle per second).
