What Are Common Mobile Screen Refresh Rates ?
Screen refresh rate is significant because it affects the visual quality and smoothness of the display. A faster refresh rate means the screen is drawn more often per second. It results in smoother motion representation and reduced motion blur, especially in fast-paced activities like gaming or video playback. Additionally, a higher refresh rate can reduce eye strain and provide a more immersive visual experience for the user.
What is Screen Refresh Rate
The screen refresh rate in a mobile phone refers to the number of times the screen is drawn to show new content per second. Its measuring unit is in Hertz (Hz), and modern smartphones’ most common refresh rates are 60Hz, 90Hz, and 120Hz. A higher refresh rate means a smoother visual experience, reduced motion blur, and improved overall display quality.

How To Calculate Screen Refresh Rate
To calculate the screen refresh rate of a mobile phone, you can divide the total number of frames displayed in one second by the number of times the screen is redrawn or refreshed in that exact second.
For example, if the phone displays 90 frames in one second and the screen is refreshed 90 times in that exact second, then the screen refresh rate would be 90Hz (90 frames ÷ 1 second = 90Hz).
But this can be influenced by various factors such as software optimization, hardware limitations, and battery usage. It may not always match the theoretical refresh rate calculated by the formula above.
What are Different Types Of Screen Refresh Rates
As we already discussed, many screen refresh rates are available, but for mobile phones, generally, 60,90,120,144 Hz are used. Let’s see it in detail.

60 Hz
This is the standard refresh rate for most monitors, laptops, and smartphones. A 60 Hz refresh rate is suitable for basic computing tasks and standard video playback but may not be ideal for fast-paced games or high-speed video content.
75 Hz
A 75 Hz refresh rate is slightly higher than the standard 60 Hz and provides a noticeable improvement in smoothness. This refresh rate is standard in entry-level gaming mobiles and is suitable for casual gaming and basic multimedia tasks.
However, compared to more modern displays with higher refresh rates, such as 90Hz or 120Hz, a 75Hz refresh rate may not provide as noticeable of an improvement in display quality and smoothness. Other factors such as resolution, colour accuracy, and brightness also play a significant role in determining overall display performance.
90 Hz
A 90Hz refresh rate provides a smoother and more fluid visual experience than a traditional 60Hz screen, especially when navigating menus or scrolling through websites. It can also provide improved gaming performance, with less motion blur and more responsive touch controls.
Smartphones with 90Hz screens are becoming more common, and their marketing as having an “ultra-smooth” display. However, it’s important to note that a high refresh rate alone does not guarantee good display quality. Other factors, such as colour accuracy, resolution, and brightness, also significantly determine overall display performance.

120 Hz
A 120Hz refresh rate provides a significantly smoother and more fluid visual experience compared to a typical 60Hz or 75Hz screen. This is particularly noticeable in fast-paced activities such as gaming or video playback, where the high refresh rate reduces motion blur and improves overall display quality.
144 Hz
The 144 Hz refresh rate is the most common refresh rate for gaming monitors and provides an even smoother visual experience compared to 120 Hz. This refresh rate is ideal for demanding gaming and multimedia tasks and is a popular choice for competitive gamers.
Other Screen Rates
In addition to these standard refresh rates, there are also adaptive refresh rates technologies, such as Nvidia G-Sync and AMD FreeSync, that can dynamically adjust a display’s refresh rate to match the frame rate of the content being displayed. This helps eliminate screen tearing and stuttering, providing a smoother and more fluid visual experience.
What To Expect
It’s important to note that a higher refresh rate is only sometimes necessary for everyone, and the benefits may not be noticeable. Factors such as screen size, resolution, and visual content will all play a role in determining the perceived smoothness of a display. A higher refresh rate can also increase power consumption and result in shorter battery life on mobile devices.
Final Take Away
In conclusion, the type of screen refresh rate you choose will depend on your needs and preferences. A 60 Hz refresh rate is suitable for basic computing tasks and standard video playback. In contrast, higher refresh rates, such as 144 Hz or 240 Hz, are ideal for demanding gaming and multimedia tasks. Additionally, adaptive refresh rate technologies can provide an even smoother visual experience by dynamically adjusting the refresh rate to match the content’s frame rate.
