The Samsung Galaxy S20 and its entire family represent a significant leap in the world of smartphones, especially due to the integration of technological advances in their screens, such as the revolutionary 120 Hz refresh rateThis article explores in-depth how this feature works, its benefits and limitations, how to activate it, its impact on battery and user experience, and compares the S20's performance with other phones on the market.
What is the 120Hz refresh rate and why does it matter on the Galaxy S20?
La refresh rate The speed of a screen, measured in hertz (Hz), indicates the number of times the display updates its image per second. In the case of conventional mobile phones, it is common to find 60 Hz. However, 120 Hz of the Samsung Galaxy S20 double that amount, allowing for a much smoother and more fluid display. This translates into a clearer and more enjoyable visual experience, especially visible when browsing, scrolling lists, playing videos, or playing games.
The technology implemented in the Galaxy S20 is Dynamic AMOLED, capable of displaying up to 120 frames per second. This advancement, initially inherited from gaming-oriented monitors and laptops, has now reached high-end smartphones to improve system animations, game responsiveness, and all multimedia content.
Advantages of 120Hz frequency: Improved user experience
- Ultra-smooth interface: System animations, web navigation, and menu navigation feel much faster and more natural.
- Advantage in games: Video games that support high refresh rates display sharper images with less blur in fast-paced scenes, improving gameplay.
- Videos and multimedia: While most content doesn't exceed 60 fps, the smoothness of scrolling between videos and interacting with apps is noticeably improved.
- Improved tactile response: The screen can obtain more precise data about finger positions, improving tactile response especially in demanding games.
Limitations of the 120Hz frequency on the Galaxy S20
Despite these notable advantages, the 120Hz refresh rate on the Galaxy S20 has certain technical and software limitations that users should be aware of to manage their experience:
- 120Hz mode only available in FHD+: The highest refresh rate (120 Hz) cannot be used at maximum WQHD+ resolution.
- Auto resolution: The device automatically downgrades to 60Hz if WQHD+ is selected in the display settings. Allowed combinations are: FHD 60Hz, FHD 120Hz, WQHD 60Hz. This means you can't enjoy the highest resolution and highest fluidity simultaneously.
- Energy consumption: 120Hz increases the screen's power consumption, which significantly affects battery life.
- Automatic deactivation under certain conditions: The system can automatically force the frequency to 60 Hz when the battery level drops below 5% or the internal temperature exceeds 42 degrees Celsius. This intelligent management aims to prevent overheating and preserve battery life.
- Incompatible applications: Some applications, such as the camera and Google Maps, are forced to run at 60Hz even when the system is in 120Hz mode, due to power and performance considerations.
How to enable 120Hz on the Galaxy S20: Step-by-step setup
To take advantage of the impressive 120Hz refresh rate on your Samsung Galaxy S20, follow these steps:
- Login to Settings of the System.
- Go to the section Screen.
- Select option Fluidity of movements o Refresh rate.
- Active High refresh rate (120 Hz).
- If you have the maximum resolution selected WQHD+, you will need to lower it to FHD+ to activate 120 Hz. Go to Screen resolution and choose FHD+.
From the moment you complete these steps, you'll notice a difference in the fluidity of the interface and scrolling. You can test it by browsing content-heavy websites or quickly scrolling through long lists to see the difference.
Impact of 120Hz Refresh Rate on Battery Life: How Much Battery Does It Consume?
One of the most delicate aspects when activating the 120 Hz is the battery consumptionNumerous independent tests have confirmed that increasing the refresh rate translates into increased energy consumption. For example, battery life is significantly reduced. In continuous browsing tests, the difference can be as much as almost 25% less usage time with respect to 60 Hz mode.
- In 60Hz mode, a Galaxy S20 Ultra can achieve up to almost 12 hours of intensive use.
- Switching to 120 Hz drops battery life to just over 9 hours, which in real-world conditions can mean several hours less daily usage.
The system is designed to offer a balance between performance and battery life. Therefore, 60Hz mode is usually enabled by factory default, allowing the user to decide when to prioritize fluidity over battery life.
Why does Samsung limit 120Hz to FHD+? Technical explanation and comparison
Samsung's decision to limit the 120Hz frequency to FHD+ resolution only responds to two fundamental reasons:
- Autonomy and thermal management: Running the display at WQHD+ and 120Hz simultaneously puts a huge strain on the phone's GPU and circuitry, which can result in excessive power consumption and increased heat.
- Sustained performance: Keeping these two settings at maximum could force the system to limit performance in other areas, compromising the user experience.
While other manufacturers allow you to unlock high refresh rates (such as 90Hz on Google or OnePlus models) at maximum resolution, the jump to 120Hz is a bigger challenge. The Galaxy S20 strikes a balance between the visual experience and practical use of the device, automatically adjusting to protect the battery and hardware.
Can 120Hz be enabled with WQHD+ using alternative methods?
At the moment, Samsung only allows the combination of FHD+ and 120Hz. Some advanced users have explored methods through root to unlock 120Hz in WQHD+, although this may void warranties, affect system stability, or cause dangerous overheating. From a technical and safety standpoint, It is not recommended to modify these settings through root. except for very specific tests and low advanced knowledge.
Automatic refresh rate management and intelligent optimization
The Galaxy S20 operating system is designed to intelligently and automatically adjust the refresh rate. Below are the main cases in which the device decides to modify the refresh rate:
- When the battery level drops to 5% or less, the display automatically switches to 60Hz to save power.
- If the battery temperature exceeds 42Ā°C, the system reduces the frequency to 60 Hz to prevent overheating.
- When running applications such as camera, Google Maps or certain games that do not support 120Hz, the phone adjusts the output to ensure compatibility and optimize resources.
- During low-motion tasks or in applications that do not benefit from a high frequency, the system may temporarily revert to 60 Hz.
In this way, the user obtains a optimal balance between fluency and autonomy, without worrying about manually managing each application.
Comparison with other high refresh rate smartphones
The Galaxy S20 is among the first phones to offer 120Hz, but it's not alone. Models like the Nubia RedMagic 5G can reach up to 144Hz, although in general, the visual difference between 120 and 144Hz may be barely noticeable for most users. The important thing is stability, panel quality, and operating system optimization.
- Nubia RedMagic 5G: 144 Hz, focused on gaming, with higher battery consumption.
- OnePlus 8 Pro: It allows 120 Hz at different resolutions, but at the cost of a significant reduction in battery life.
- Pro iPhone 13: Uses variable rate (ProMotion up to 120 Hz), dynamically adjusting based on usage.
The Galaxy S20 stands out for offering a balanced and configurable visual experience, in addition to possessing one of the best AMOLED displays of the market according to technical analysis by industry experts.

Recommendations to make the most of the 120 Hz frequency
To get the most out of 120Hz on your Galaxy S20, keep the following tips in mind:
- Activate 120 Hz only when you need it: If you prioritize battery life on long trips or tasks, you can maintain 60Hz mode and switch to 120Hz for gaming or multimedia viewing.
- Customize the resolution: Using the display in FHD+ is sufficient for most daily uses and allows access to 120 Hz.
- Monitor battery usage: If you notice a sudden drop in battery life, check whether you have the 120 Hz frequency activated and whether it is really essential for the task you are performing.
- Avoid overheating: If the device becomes excessively hot during intensive sessions, consider temporarily reducing the frequency to 60 Hz.
- Keep your software up to date: Samsung regularly releases updates that improve display management and battery efficiency.
Galaxy S20 Refresh Rate FAQ
