How to Change the Screen Frequency on Xiaomi: A Complete Guide to All Models

Screen refresh rates are one of the key parameters that affect the smoothness of the picture and the responsiveness of the smartphone. POCO This setting is not always available in the obvious way, and in some models it can only be changed through hidden menus. MIUI to the engineering menu and ADB-team.

If you notice that the animations on the screen twitch, the games slow down or the battery runs too fast, the problem may be in the wrong frequency. But before you change the parameters, it is important to understand what frequency your model supports and how this will affect the autonomy. For example, 120 Hz gives a smoother image, but increases the load on the processor and battery by 15-25% compared to 60 Hz.

In this instruction, we will consider:

• 📱 How to check the current screen frequency on Xiaomi
• ⚙️ Standard and hidden ways of frequency change
• ⚡ The effect of frequency on battery and performance
• 🔧 Solving problems if the setting is not available

1.What frequencies support Xiaomi smartphones

Not all Xiaomi devices support high refresh rates, for example, the budget models Redmi 10A or POCO M4 Pro are limited to 60 Hz, while flagships like Xiaomi 14 Ultra or Black Shark 5 Pro offer up to 144 Hz. Below is a table with popular models and their supported frequencies:

Adaptive frequency (for example, 1-120 Hz on Xiaomi 14) automatically adjusts to the content: when watching video, it decreases to 48-60 Hz, and in games it rises to a maximum, which helps to save battery power without losing smoothness where it is really needed.

How do you know your model? Go to Settings → About Phone → Model. If your device isn’t in the table, check the specifications on Xiaomi’s official website or GSMArena.

💡

On some models (such as the POCO X3 Pro), 120Hz is only available when selecting the performance mode in the battery settings.

2. How to change the screen frequency through standard MIUI settings

On most modern Xiaomi devices with MIUI 12-15, the screen frequency is adjusted through the display menu.

1. Open Settings (the gear icon on the main screen).
2. Go to the Screen section.
3. Select the screen refresh rate (some firmware may call the screen smoothness).
4. Set one of the available values: 60 Hz, 90 Hz, 120 Hz or Auto (adaptive mode).

If you don't have a screen refresh rate, your model doesn't support changing that setting through the standard menu, in which case you can try the alternative methods described below.

Battery charge of at least 30% |

Close all background applications |

Make a backup copy of the settings (optional)-->

What to do if you don't have "Update Frequency"? On some firmware (especially older versions of MIUI or custom builds), this parameter may be hidden. Try to upgrade to the latest version or use the methods in the following sections.

⚠️ Attention: On devices with AMOLED-high frequency combined with maximum brightness can lead to accelerated wear of the matrix.

Change frequency through the engineering menu (for power users)

If standard settings don’t allow you to change the frequency, you can try the engineering menu, which works on most Xiaomi devices, but you need to be careful – incorrect actions can lead to malfunctions in the screen.

Instructions:

1. Open the Phone app.
2. Enter the combination: ##4636###.
3. In the menu that opens, select Hardware Testing (or Hardware Testing).
4. Go to the Display or Screen section.
5. Find the Refresh Rate and select the desired value.

If #4636### doesn’t work, try the alternative codes:

• 🔢 ##3644633## - Display test on some Redmi models.
• 🔢 ##225## - Screen calibration (may include frequency settings).

⚠️ Note: In the engineering menu, you can accidentally change other display settings, such as color profile or sensor calibration!

4.Use of ADB to force frequency change

If none of the previous methods worked, you can use ADB (Android Debug Bridge), which is suitable for advanced users and requires connecting a smartphone to a computer.

Step-by-step:

1. Turn on Developer Mode: Go to Settings → About Phone. Click 7 times on MIUI until the notification "You're a developer" appears.

USB debugging

Settings → Additional → For Developers

ADB-driver

adb shell settings put global peak_refresh_rate 120

(Replace 120 with the desired frequency: 60, 90, etc.)

Reset the device.

To return automatic mode, use the command:

adb shell settings put global min_refresh_rate 60


adb shell settings put global peak_refresh_rate 120

Check the current frequency through ADB:

adb shell settings get global peak_refresh_rate

💡

ADB-commands allow you to change the frequency even on devices where this option is hidden in the MIUI. However, after updating the system, the settings may reset.

5.The effect of screen frequency on battery and performance

The high refresh rate (90-144 Hz) significantly increases the load on the CPU and graphics chip, leading to two key consequences:

• 🔋 Accelerated battery discharge – 15–30% faster at 120 Hz compared to 60 Hz.
• 🔥 Increased heat – especially noticeable in games and resource-intensive applications.

Below is a comparison table of the impact of frequency on autonomy (testing on Xiaomi 13 Pro with the X-ray). AMOLED-screen):

When should you use a high frequency?

• 🎮 In the game Genshin Impact, Call of Duty Mobile, PUBG) — The difference between 60 and 120 Hz is particularly noticeable.
• 📱 When scrolling through social media or web pages.

When is it better to lower the frequency?

• 📺 When watching video (most videos have a frequency of 24-60 fps, so 120 Hz do not give advantages).
• 📚 When reading books or working with documents.
• 🔋 If there is little charge left, and you need to extend the autonomy.

💡

On devices with LTPO-In the case of screens (e.g. Xiaomi 14), the adaptive frequency automatically drops to 1 Hz in static scenes (e.g., when reading), saving battery life.

6 Problem Solving: Frequency does not change or is reset

If you have changed the frequency but it doesn’t apply or resets after the reboot, check the following points:

Problem 1: Configuration is not available in MIUI

• 🔄 Update the firmware to the latest version (Settings) → Updating the system).
• 📱 Check if your model supports high frequency (see table at the beginning of the article).
• 🛠️ Install custom firmware (e.g. Pixel Experience or LineageOS) if the official MIUI limits the functionality.

Problem 2: Frequency resets after rebooting

• 🔧 This is typical for devices where the frequency has changed through the ADB. To fix the settings, use the SetEdit application to edit system parameters.
• 📲 Check if the settings are reset due to energy saving modes (Settings) → Battery → Power regimens).

Problem 3: The screen flickers or twitches after changing frequency

• 🔄 Return the standard frequency (usually 60 Hz) and restart the device.
• 🛠️ Check if the frequency is in conflict with the switched on DC Dimming (Settings) → Screen. → DC Dimming).
• 📱 Update the display drivers through Settings → Updating the system → Update packages.

⚠️ Note: If the frequency changes ADB or the engineering menu screen stopped working correctly (artifacts, no image), reset to factory settings (Settings) → Additionally. → Recovery and reset. This will bring back the standard display settings.

7 Optimal frequency settings for different scenarios

To balance between smoothness and autonomy, use the following recommendations:

On devices with adaptive frequency (for example, Xiaomi 13/14), it is best to leave the Auto mode. The system itself will adjust the frequency depending on the content, balancing between smoothness and autonomy.

How to check the actual screen frequency?

• 📱 Install the Refresh Rate Test application.
• 🔍 In the engineering menu (#4636##) find the Real-time Refresh Rate.

💡

On devices with LTPO-Adaptive frequency works more efficiently than manual settings, saving up to 20% charge without loss of smoothness.
