Modern smartphone users are increasingly paying attention to the smooth operation of the interface and games. Screen refresh rate has become one of the key parameters when choosing a device, directly affecting visual comfort. However, even with powerful hardware, many do not know how to activate the maximum capabilities of their display.
By default, manufacturers often set the mode auto-select or standard 60 Hz to save battery power. This gives the illusion that the phone doesn't support higher values, although the hidden potential may be available in the settings menu. Let's take a look at how to force enable the desired frame rate on your device.
In this instruction we will look at standard activation methods, using engineering menus and third-party utilities. You will learn to distinguish software interpolation from real hardware High Refresh Rate. We will also touch on the issues of compatibility of specific models and the influence of the mode on the power consumption of the system.
What is the screen hertz and why change it
Refresh rate (refresh rate) is measured in Hertz (Hz) and shows how many times per second the image on the display is completely redrawn. Standard screens run at 60Hz, which means 60 frames per second. More advanced panels offer 90 Hz, 120 Hz and even 144 Hz.
High Hertz makes system animations, scrolling through social media feeds and cursor movement incredibly smooth. The eye perceives the picture as more alive and responsive. In games, this gives a competitive advantage, allowing you to see more frames of action per unit of time.
However, it is worth understanding the difference between the refresh rate of the matrix and the FPS (frames per second) that the processor produces. If your chipset is not capable of generating 120 frames in the game, then turning on 120 Hz on the screen will not make the graphics smoother, although the interface will become more responsive.
⚠️ Warning: Setting the maximum frame rate may increase power consumption by up to 20-30%. If you are planning a long trip without charging, it is better to temporarily reduce this parameter.
For maximum smoothness, it is necessary that both the system interface and the specific application support high frame rates.
Standard activation through system settings
Most modern smartphones based on Android 10 and higher have built-in frequency switch. Manufacturers place this option in different sections of the menu, but the logic remains the same. Usually the path is through the display settings.
To find the desired option, go to Settings → Display → Refresh rate. In some shells, such as OneUI from Samsung or MIUI from Xiaomi, the path may be different. For example, in the color and brightness menu, additional parameters are sometimes hidden.
In the menu that opens, you will be offered a choice between modes. The standard option is often called "Automatic" or "Adaptive Frequency". In this mode, the smartphone itself decides when to raise the Hertz to the maximum, and when to lower it to 60 Hz to save money.
- 📱 Standard mode: fixes the screen operation at 60 Hz, maximum battery saving.
- 🚀 High frequency: forcedly keeps 90/120 Hz, maximum smoothness.
- 🔄 Adaptive mode: Dynamic switching depending on the content.
If you want to ensure smooth gaming, choose the high frequency mode. However, remember that some heavy games may limit FPS themselves, regardless of screen settings. Check the settings inside the game application itself.
Settings for specific brands and skins
The interfaces of different manufacturers differ greatly from each other. What is easy to find on “pure” Androidcan be hidden in the depths of the menu of Chinese brands. Let's look at the features of popular shells.
Device owners Samsung should look for the option in the section Display → Smoothness. There is no explicit indication of Hertz, only a switch for “Standard” and “High”. Selecting “High” activates the maximum available for your model.
Users Xiaomi and Poco will find the setting in the menu Screen → Refresh rate. Interestingly, in MIUI you can often select specific values, for example, 60, 90 or 120 Hz, if the screen supports several fixed modes.
Smartphones OnePlus i Oppo s shell ColorOS offer the "High refresh rate" mode in the main screen settings. The latest versions of the software have also added the "Intelligent Frequency" function, which analyzes the scene.
| Brand / Shell | Menu path | Name features |
|---|---|---|
| Samsung (OneUI) | Display → Smoothness of movement | High / Standard |
| Xiaomi (MIUI/HyperOS) | Display → Refresh rate | Select specific Hz |
| OnePlus (OxygenOS) | Display → Refresh rate | High / Default |
| Google Pixel | Display → Smoothness | Adaptive / Standard |
Hidden developer settings
In some cases, even if the switch is not in the menu, the option may be available in the developer menu. Path: Settings → About phone → tap on the build number 7 times → Settings for developers → Simulate additional frame rate (for debugging).
Using the engineering menu and ADB commands
If there is no switch in the regular menu, you can try advanced methods. Engineering menu allows accessing hidden equipment parameters. Be careful: incorrect changes can lead to unstable operation of the system.
To enter the engineering menu on many devices, use the code in the dialer. Try entering ##3646633## or ##4636##. The interface may differ depending on the processor (MediaTek, Qualcomm).
In the menu MediaTek go to the tab Hardware Testing → Display. There may be an item Set CABC or frequency settings. Changing the parameters here requires an understanding of the technical specifications of your matrix.
adb shell wm size
adb shell wm density
A safer method is to use ADB (Android Debug Bridge) via a computer. Connect your phone, enable USB debugging and enter commands to check the current display settings. Directly changing the frequency via ADB is not possible on all devices without root access.
⚠️ Attention: Interfering with the engineering menu may void the warranty. Take screenshots of the original settings before any changes so that you can return everything as it was.
☑️ Preparing to use ADB
Checking the real support of the matrix
Often users turn on high frequency in the settings, but do not see the difference. This happens if the matrix does not physically support the declared mode or works in interpolation mode?
There are special test sites and. applications that display the frame counter in real time. Open a browser on your phone and go to a resource with a smoothness test (for example, a ball movement test).
Applications like Device Info HW or AIDA64will also help. They read data directly from the display controller. data-i="116">and parameter Display and parameter Refresh Rate.
Pay attention to the marking LTPO. If this technology is indicated in the characteristics, it means that the screen can dynamically change the frequency from 1 Hz to 120 Hz. This is the most modern and energy-efficient type of matrix for today.
- 🔍 Visual test: rapid movement of objects should not be left behind. loops.
- 📊 Diagnostic software: will show the current active frequency in real time.
- 📄 Specifications: check the official website of the model manufacturer.
If an application shows 60 Hz despite the 120 Hz setting being enabled, the specific application may not be optimized. Many banks and older apps are strictly limited to 60 frames at the code level.
The presence of a switch in the menu does not guarantee 120 Hz operation in all applications. level of the app code of the app itself.
The effect of high frequency on the battery and heating
Increasing the number of frames per second requires more computing power from the graphics accelerator and updates the pixels of the matrix more often. This inevitably leads to an increase in power consumption?
In scenarios of reading text or viewing static pictures, the difference is minimal, especially on screens with adaptive synchronization technology. However, in dynamic scenes, games and when scrolling quickly, the load increases significantly.
It is also worth considering the heating of the case. When playing for a long time at maximum frame rates, the processor and GPU are pushed to their limits. This may result in throttling (reduced performance) to protect components.
⚠️ Attention: Display specifications and power saving algorithms are constantly updated by manufacturers. It is better to check the latest operating time data in the latest reviews of your specific smartphone model.
It is recommended to use the “High Frequency” profile only when you really need smoothness. The rest of the time, adaptive mode is the golden mean between comfort and autonomy.
If you notice a quick discharge, try disabling high frame rates at night or when using a navigator, where the smoothness of animations is not critical.
Why is there no 120 Hz option in the settings?
Rather In total, your smartphone model is equipped with a screen with a maximum frequency of 60 Hz or 90 Hz. It is impossible to raise this value in hardware. Also, the manufacturer may have blocked this function in the software for your regional version.
Does the frame rate affect the quality of the photo?
No, the screen refresh rate does not affect the camera's performance and the quality of the pictures. This is solely a parameter for displaying images on the display. However, the viewfinder in 120 Hz mode can work smoother.
Is it possible to enable 120 Hz on an old phone?
Only if the matrix physically supports this frequency, but the manufacturer has hidden this option. Otherwise, software enlargement (interpolation) will only create the appearance of smoothness, but will add input lag.
Why do games only run at 60 FPS?
Game developers often limit frames to ensure stability across different devices or to save the player's battery. Check the settings inside the game itself, sometimes the “High FPS” option is hidden in the advanced graphics options.
What is adaptive refresh rate?
This is a technology in which the screen automatically changes the hertz depending on the content. When reading a book it drops to 1-10 Hz, and in dynamic games it rises to 120 Hz. This saves charge without loss of smoothness.
