Modern smartphone users are increasingly paying attention not only to the resolution of the screen, but also to the frequency of its update. Owners of Xiaomi brand devices and the sub-brand Redmi often face a situation where the hardware screen is capable of operating at high frequencies, but is software limited to the standard 60 Hz. This limitation can be due to marketing policy or optimization of battery operation in certain versions of firmware.
In this article, we will discuss how to increase the hertz on a Xiaomi Redmi phone without losing the guarantee and stability of the system. We will look at the standard methods, the capabilities of the engineering menu and third-party applications that allow you to unlock the potential of your display. It is important to understand that interfering with system settings requires careful and accurate follow the instructions to avoid errors.
What gives a high frequency of screen updates
The refresh rate of the screen, measured in Hertz (Hz), determines how many times per second the image on the display is updated. The standard value has long been 60 Hz, but modern flagships and mid-range devices offer 90 Hz, 120 Hz and even higher. Increasing this indicator on Redmi Note or Xiaomi Mi smartphones makes scrolling the tape on social networks and the settings menu visually smoother and more pleasing to the eye.
For gamers, high hertz is a critical parameter. In dynamic shooters and racing, increasing frames per second (FPS) allows you to respond faster to enemy actions. The picture becomes less blurry when the camera turns sharply, which gives you a competitive advantage. However, it is worth considering that the constant operation of the display at the maximum frequency leads to increased power consumption.
Not all users immediately notice the difference between 60 and 90 Hz, but after getting used to the return to low values seems to be a jerky. hardware support for high frequency should be present in the screen matrix, software unlocking will not create 120 Hz on a physically 60 Hz display.

- 👁️ Reducing visual eye fatigue during prolonged reading of text.
- 🔋 Faster battery discharge with constant operation at maximum.
Check the current hertz and screen capabilities
Before you make changes to your system, you need to know exactly how fast your screen is running right now. The MIUI shell often lacks a direct frequency widget on the desktop, so you'll have to use the developer's built-in tools or third-party utilities to help you understand whether it makes sense to try to change something or if the system is already working at the limit of the matrix.
The easiest way is to activate the developer menu. Go to Settings → About Phone and quickly click on the MIUI build number seven times. Once you have become a developer, a new menu will open in the "Additional" section. There you can find the "Show Update Frequency" option, which will display the FPS counter in real time.
An alternative and more informative method is to use specialized applications from Google Play, such as Device Info HW or Screen Test, which read data directly from the display controller and show not only the current, but also the minimum and maximum frequency supported, this knowledge is critical to planning further optimization actions.
It's worth noting that some models have adaptive refresh rates, which means that the system automatically lowers the hertz to 30 or 10 Hz in a static image to save energy.
Standard methods of increasing hertzovka in MIUI
In most modern Xiaomi and Redmi smartphones with 90Hz and 120Hz screens, the frequency setting is already built into the standard menu. Manufacturers often hide it or offer a choice between Standard (60Hz) and High frequency. Sometimes there is a default option that allows the system to decide when to increase the hertz, but this mode does not always work correctly.
To find these settings, go to Settings → Screen → Update Frequency. If you have an AMOLED model, there may be an "Elevated Update" switch. Turning on this option forces the display to run at 90 or 120 Hz even in simple applications, where the system usually resets the frequency to save charge.
However, in some regions or firmware versions (especially Global). ROM) This option can be hidden even if the Chinese version is not available (CN ROM) In this case, you can't use standard methods to increase the hertz, and you have to resort to more sophisticated methods through the engineering menu or ADB-And remember, the forced high-mode switching always affects autonomy.
⚠️ Warning: Forced inclusion of the maximum frequency in the standard settings can lead to heating of the case with prolonged use of navigation or video.
Using the Engineering Menu to Unlock
The Engineering Mode is a hidden part of the system designed to test equipment in the factory, and this is where you can often find switches hidden from the average user, accessed by a standard Redmi call by entering a special code, such as ##6484## or #3646633##, although the codes may differ depending on the processor (MediaTek or Snapdragon).
In the testing menu, you need to find the section associated with the display (often called "Hardware Testing" → "Display" or "LCM"). Inside, you can find a "Set FPS" or similar item where you can select the desired frequency. Change the parameter here applies instantly, but not always saved after a reboot.
Be extremely careful when changing the settings in the engineering menu. Incorrectly selected resolution or timing settings can cause the screen to go out or the image to become unreadable. The engineering menu does not have a system of protection against user errors, like a regular MIUI, so all actions are performed at your own risk.
It’s worth mentioning that on Snapdragon processors, access to deep display configuration via the engineering menu is often blocked, and in such cases enthusiasts use a computer and USB debugging to send a command to change the display configuration directly to the driver.
Adjustment through ADB and hidden commands
For advanced users who are not afraid of the command line, there is a method of changing the hertz through the Android debugging bridge (ADB). This method allows you to make changes to the system configuration files without the need to obtain superuser rights (Root), which retains the guarantee at the software level, USB-cable and installed drivers ADB.
First, you need to activate the debugging USB Then, when you connect your smartphone to your PC, open the command line and type a command to access hidden display settings. Often, you use a command like adb shell settings put system. peak_refresh_rate 120, where 120 — However, the syntax may differ depending on the Android version and shell.
adb shell wm size
adb shell wm density
adb shell settings put system min_refresh_rate 60
adb shell settings put system peak_refresh_rate 120This method is safer than direct editing system files, as changes are easy to roll back. Just enter a command with standard values (for example, 60 Hz) or simply restart the device if the settings were not rigidly fixed. ADB gives flexibility in testing different values without the risk of "bricking" the phone.
It's important to understand that not all teams work on all devices. Manufacturers often patch these security and capability holes in new security updates. If the command doesn't work, then your firmware version has locked this method at the core level.
Comparison of methods and risk table
The choice of how to increase the hertz is dependent on your technical background and the device model. The standard settings are safe but limited. The engineering menu is powerful but dangerous. ADB requires a computer, but it gives a good balance between control and security. Below is a comparison table to help determine the method.
| Method | Difficulty | Risk to the system | Retention after reboot | Demands a PC. |
|---|---|---|---|---|
| Staffing arrangements | Low. | No. | Yes. | No. |
| Engineering menu | Medium | High-pitched | Partially. | No. |
| ADB team | Tall. | Low. | Depends on the team. | Yes. |
| Third-party APKs | Medium | Medium. | No (requires launch) | No. |
When using third-party applications from unverified sources, there is a risk of data leakage or malicious code. Data security should be a priority. Always check the permissions the application requests to change the screen frequency. If a simple application requests access to contacts or a microphone, this is an alarm.
⚠️ Note: Installation of modified system applications (modded) APK) Unlocking Hertz can lead to conflicts with security updates Google Play Protect.
The most stable solution is to use the capabilities provided by the manufacturer itself in the current version of MIUI. If the screen supports 120 Hz, but there is no option, you may want to wait for a firmware update, where this feature will be added officially, as is often the case with models of the Redmi K or Xiaomi Mi T series.
The effect of high hertz on battery and heating
Increasing the refresh rate of the screen directly affects the GPU and the power controller. The display starts to consume more power because it needs to redraw the picture more often. In use cases where the content is static (reading a book, viewing a photo), high hertzovka is an overuse if adaptive technology is not included.
Heat generation also increases. With long gaming sessions at maximum graphics and frame rates, the smartphone may start trottling (reduced performance) due to heat. This can lead to the opposite effect: instead of a smooth picture, you get friezes and lags, as the system will try to cool the processor.
To minimize the negative impact, it is recommended to use energy saving modes that automatically limit the frequency when the battery is low, and it is also worth keeping an eye on background processes that can load the system and cause frequency switches, creating twitchy animations.
