Modern Xiaomi and Redmi smartphones are equipped with displays with high refresh rates, which makes the interface incredibly smooth and animations responsive. However, many users do not even suspect that their device works in an economical mode, and do not know how to change the hertzovka on the shaomi for maximum visual comfort. Standard settings often limit frame rates to save battery power, hiding the true potential of the matrix from the owner.
In this article, we will take a closer look at all the available ways to switch screen modes, from standard settings menus to advanced methods through the engineering menu and ADB. You will learn the difference between adaptive frequency and forced mode, and understand why some applications may not support high hertz without additional manipulation.
Before you make any changes, it’s important to understand that increasing frames per second directly affects your power consumption. If you prioritize maximum autonomy for two days, choosing 60 Hz may be worth it, otherwise switching to 90 or 120 Hz will give you a new experience with the MIUI or HyperOS operating system.
What is the screen refresh rate and why change it
The refresh rate of the screen, measured in Hertz (Hz), determines how many times per second the image on the display is updated. Standard screens operate at 60 Hz, which means 60 frames per second. More modern Xiaomi models offer 90, 120 and even 144 Hz, making scrolling the news feed, menus and games significantly smoother and more pleasing to the eye.
The difference between 60 Hz and 120 Hz is visible to the naked eye immediately after the switch. Animations become oily, the sensation of delay disappears when touching, and text ceases to blur when scrolling quickly. For gamers, a high hertz is not just a beautiful picture, but a real advantage in the speed of reaction and smoothness of what happens on the screen.
⚠️ Warning: Constant operation of the screen at maximum frequency (for example, 120 Hz) can reduce the battery life of the smartphone on 15-20% versus the regime 60 Hz, especially when using bright wallpaper and heavy applications.
However, not all applications are optimized for high-frequency performance: Some video services or older games can force the screen to switch to 60Hz mode to save resources or because of the limitations of the content itself. Understanding this mechanism will help you avoid frustration if you don’t see the expected smoothness in a particular game.
Changing the hertz is important not only to improve comfort, but also to solve compatibility problems. Some users, on the contrary, are looking for a way to lock 60 Hz to eliminate twitching in applications or extend the life of the battery. The flexibility of the Android system in conjunction with the shell from Xiaomi allows you to choose the optimal balance.
Standard display settings in MIUI and HyperOS
The easiest and safest way to change the refresh rate is to use the built-in settings menu. In the latest versions of MIUI 12/13/14 shells and the new HyperOS, screen algorithms have become smarter, offering the user multiple use cases.
To access the settings, you need to go to the Settings menu → Screen. → Update frequency: Here, the system will suggest you to select one of the available modes if your smartphone model supports switching. Default (automatic choice) and Maximum (forced high frequency) options are usually available).
- 📱 By default: the system decides when to increase the hertz for smoothness, and when to reduce to save energy.
- 🚀 Maximum: The screen is always at its limit (e.g. 120Hz), regardless of the content.
- 🔋 Standard (60 Hz): Forced frequency restriction for maximum charge savings.
Some models, such as the Redmi Note series or Xiaomi Mi flagships, may feature Adaptive Frequency, which allows the screen to dynamically change the hertz from 1 Hz (for static image) to 120 Hz (for gaming and scrolling), the most energy-efficient option that most users recommend using.
If you didn’t find the switch in this menu, it’s possible that your smartphone model has a fixed screen frequency or the manufacturer has hidden this option in a specific regional firmware, in which case deeper customization methods may be needed, which we’ll talk about below.
💡
To check the actual frequency of the update at the moment, you can use online services like testufo.com, launched in the smartphone browser.
💡
Built-in settings are the safest method, without requiring superuser rights and without violating the device warranty.
It is worth noting that in Maximum mode, some system applications may not work stable if they have not been optimized by developers for high hertzovka, in which case it is better to return to automatic mode.
Activation of hidden modes through the engineering menu
If the standard menu doesn’t work, or if you want to unlock additional options, you can use the engineering menu, a powerful tool for diagnosing and configuring the hardware of a smartphone that is usually hidden from the average user.
To log into the engineering menu, most Xiaomi devices use a special code in the Phone app. Dial ##6484## or ##4636##. If the code doesn't work, your firmware version may block this access and you will need to install a special activator application, such as Activity Launcher.
Inside the menu, you need to find a section associated with the display, which can be called Single Test Item → Version or have a name associated with LCM (Liquid Crystal Module), depending on the model, there can be a manual frequency change.
- 🔍 Find the Refresh Rate or Frame Rate.
- 🔢 Select the desired value (60, 90, 120).
- 💾 Press Apply or OK preserve change.
⚠️ Warning: Changes to the engineering menu can cause system instability or device “fixing” if you choose unsupported settings!
It is important to understand that not all arrays are physically capable of operating at higher frequencies. Trying to set 120 Hz on a screen that supports only 60 Hz will either result in no effect or a black screen and you need to reset your settings.
After changing the settings through the engineering menu, it is recommended to restart the device. If after turning on you see artifacts, stripes on the screen or the phone freezes, you need to reset the settings to the factory as soon as possible or return the original values if the screen allows you to do this.
☑️ Check before entering the engineering menu
Using ADB to Force Hertzov Change
For advanced users who are not afraid of the command line, there is a method of changing the refresh rate through ADB (Android Debug Bridge) debugging, which allows you to penetrate system processes and change parameters hidden in the normal interface.
To start, activate the developer mode. Go to Settings → About Phone and quickly press 7 times on the MIUI build number. Then, in the Developer menu, turn on USB Debugging.
Connect your smartphone to your computer through USB-There's a platform on the computer. SDK Platform Tools: Open the terminal or command line in the tool folder ADB and enter a command to check the connection:
adb devicesOnce the phone has confirmed the connection, you can try changing the frequency. However, there is no universal command for all Xiaomi models, since manufacturers often change the system properties.
adb shell wm size 1080x2400
adb shell wm density 440Although these commands change resolution and density, the hertzing itself often requires changing system files or using processor-specific (Snapdragon, MediaTek) commands. For example, some processors work by changing the property. debug.sf.enable_gl_tracing, But it's more like debugging.
A safer and more effective method through ADB is to activate hidden settings menus.
adb shell am start -n com.android.settings/.Settings$DisplayActivityYou can open the extended display menu if it's hidden, but remember that forcing the driver-level frequency change through ADB without proper support from the kernel will not work.
If you've successfully changed the setting, the changes can take effect after the reboot. If the phone has stopped responding to touch, try plugging in. USB-mouse or keyboard through OTG, to reset the settings back.
Comparison of display modes
To make it easier for you to choose the optimal mode, we have prepared a comparison table that will help you weigh the pros and cons of each Hertz configuration on your Xiaomi device.
| Parameter | 60 Hz (Standard) | 90/120 Hz (High) | Adaptive |
|---|---|---|---|
| Smoothness of the interface | Basic | Maximum | Dynamic. |
| Battery consumption | Low. | High-pitched | Optimal. |
| Heating the device | Minimum | Notable under load | Moderate. |
| Compatibility of games | 100% | Depends on optimization | Depends on optimization |
As you can see from the table, 60Hz remains the king of energy efficiency. If you use your phone primarily for calls, messengers and navigation, you may not need a high hertz, and the difference between 10-15% of autonomy will be palpable.
120Hz and up is the choice of enthusiasts and mobile gamers. In shooters like PUBG Mobile or Call of Duty, 90 or 120 FPS support is a real advantage, but in everyday use, the difference between 90 and 120 Hz is already less noticeable than between 60 and 90.
Adaptive mode is the middle ground that all modern manufacturers are striving for. The smartphone itself understands that you are reading a book, and reduces the frequency to a minimum, and when you launch a game, it squeezes all the juices from the screen.
Why is 120Hz not available on YouTube?
The effect of hertzovka on autonomy and heating
Increasing the refresh rate of the screen is one of the most significant factors affecting the power consumption of the smartphone. the display is one of the main consumers of energy, and forcing it to update twice as often (from 60 to 120 times per second) means significantly increasing the load on the GPU and the matrix itself.
When you’re actively using a 120Hz smartphone, you may notice that the device starts to warm faster, especially in bright mode. This is normal: the processor is more active in processing graphics, and the power controller delivers more current to the backlights and screen drivers.
- 📉 Savings: In mode 60 Hz smartphone can live on 1.5-2 One hour longer with an active screen.
- 🌡️ Heat generation: High hertzovka contributes to faster heating of the case, which in summer can lead to trottling (decreased performance).
- 🎮 Gaming: In games, the load on the battery increases multiple times, and here the choice between smoothness and game time becomes critical.
The LTPO (Low-Temperature Polycrystalline Oxide) technology used in Xiaomi flagships minimizes this damage. These screens can change the frequency from 1 Hz to 120 Hz instantly. If you own such a device, feel free to set the maximum frequency - the smart system itself optimizes everything.
For budget models with a fixed frequency or a simple switch 60/90/120, the rule is simple: if you want to play and enjoy - bet the maximum, go on a long hike without charging - lower to 60 Hz.
