Where to see the refresh rate of the screen on the Xiaomi phone: all the ways

Why it’s important to know the screen refresh rate on Xiaomi

Screen refresh rates (measured in hertz, Hz) are a key parameter that affects the smoothness of content display. On Xiaomi, Redmi and POCO smartphones, this can range from the standard 60Hz to 144Hz in top models. Knowing the current frequency will help optimize performance, save battery power or activate hidden modes if supported by your device.

Many users do not even realize that their phone is not working at the maximum frequency. For example, the Xiaomi 13 Pro can use 120 Hz by default, but in the energy saving settings automatically switch to 60 Hz. Or vice versa: some budget models Redmi Note artificially limit the frequency to save resources. In this article, we will analyze all the methods of verification from standard MIUI menus to engineering modes and third-party utilities.

This is especially relevant for gamers and fans of dynamic content. The difference between 90 Hz and 120 Hz is noticeable to the naked eye when scrolling through social media feeds or in shooters like PUBG Mobile. And if you plan to buy a new Xiaomi smartphone, the ability to check the frequency of the screen will help avoid cheating sellers who may indicate inflated values in the characteristics.

Method 1: Standard MIUI settings (the simplest method)

Most modern Xiaomi smartphones allow you to view and change the refresh rate of the screen in the settings menu. This method works on devices with MIUI 12 and later, including the latest versions of HyperOS.

1. Open the Settings app** (cog icon).
2. Go to the Display section.
3. Select the screen refresh rate (some firmware may call Adaptive Frequency or Screen Smoothness).
4. The screen will display the current value (e.g. 60Hz, 90Hz, 120Hz) and the available options for switching.

If there is no such item on your menu, it could mean:

• 📱 Your model does not support frequency change (e.g. budget Redmis). 9A or POCO C31 have a fixed 60 Hz).
• 🔄 You have an outdated version. MIUI (Update the firmware through Settings → The phone. → Updating the system).

⚠️ Note: Some models (e.g. Xiaomi) 12T or POCO F4) The frequency can automatically drop to 60 Hz with a low battery charge (less than 15.

Method 2: Through device information (for all models)

If the display settings do not specify the frequency directly, you can find it through the "About the phone" section**

1. Open the Settings. → The phone.
2. Tap the MIUI version (or HyperOS build number) several times until you become a developer!
3. Go back to the main settings menu and find a new section for developers (or Advanced settings → Developers).
4. Scroll down to the Equipment or Display Information block, and the current frequency can be displayed here.

This method doesn’t work on all devices, but it often helps on models where the frequency is not controlled by the user (for example, the Redmi Note 10 with a fixed 90 Hz).

💡

On some MIUI firmware, the screen refresh rate is displayed in the Settings menu → Display → Additional → Smooth animations. You can also turn on the adaptive mode that automatically adjusts Hz to the content.

Method 3: Engineering menu (for advanced users)

The engineering menu (#4636##) contains hidden settings, including detailed display information, which is suitable for all Xiaomi models, but requires caution – do not change other settings unless you are sure of their purpose!

Instructions:

1. Open the Phone app** and enter the combination: ##4636###.

If the engineering menu does not open:

• 🔐 It may be blocked by the manufacturer (relevant to Chinese firmware).
• 📲 Try entering the code through the Calculator app** (in some versions). MIUI It works).

⚠️ Warning: Do not change the settings in the engineering menu unless you know their purpose! Incorrect settings can lead to malfunctioning of the display or even loss of warranty.

Method 4: Third-party applications for frequency testing

If the standard methods don't work, specialized utilities will come to the rescue, not only show the current frequency, but also test the stability of its operation.

How to use:

1. Install any of the applications (links above).
2. Open it and find the Display or Screen section.
3. Pay attention to the Refresh Rate string, which is the current frequency.
4. In some utilities (for example, Refresh Rate Tester), you can run a test that will show the real value (useful if the system is lying).

⚠️ Note: Some applications may show the maximum screen frequency rather than the current one. POCO X3 Pro maximum frequency is 120 Hz, but in power saving mode the phone works at 60 Hz.

Install DevCheck or Display Tester from Play Market

Open the "Display" or "Screen" section.

Find the "Refresh Rate" line (current frequency)

Method 5: Through ADB-Teams (for technical specialists)

If you're familiar with ADB (Android Debug Bridge), you can get your screen frequency through the command line, and it's universal, and it works even on locked firmware.

• 🖥️ Computer with installed ADB Tools.
• 📱 Included debugging by USB on the telephone (see Method 2, step 2-3).
• 🔌 USB-plug-in.

Instructions:

1. Connect your phone to your PC and open the command prompt (cmd in Windows or Terminal on macOS/Linux).
2. Enter the command to check the connection: Adb devices must appear serial number of your device.
3. Execute the command to get information about the display: adb shell dumpsys display
4. In the output, find the DisplayDeviceInfo block and the refresh rate bar. For example: refresh rate: 120.000000 Hz

For advanced users: If you need to force a frequency set (for example, unlock 120 Hz on an unofficial firmware), use the command:

adb shell settings put global peak_refresh_rate 120.0

But remember: this can cause overheating or accelerated battery discharge!

💡

ADB-commands are the most reliable way to know the actual frequency of the screen, since the data is taken directly from the system, not from the interface. MIUI, where they may be hidden or distorted.

Frequent problems and their solutions

Sometimes users are faced with the fact that the screen frequency does not correspond to the declared or is not regulated.

Problem 1: The frequency does not change in the settings

If the Display menu does not have an option to change the frequency, although the characteristics should be:

• 🔄 Update your firmware to the latest version (the option may have appeared in new versions). MIUI).
• 🔧 Check if the energy saving mode is set (Settings) → Battery → Energy saving regime).
• 🛠️ Install custom restoration (for example, TWRP) and run the Force module 90Hz/120Hz (power-user!).

Problem 2: Frequency floats (e.g. 60 Hz, 120 Hz)

This is normal behavior for responsive screens (e.g., Xiaomi 13 or POCO F5).The system automatically reduces the frequency for static content (e.g., reading text) and increases for dynamic (games, videos).

• 📱 Turn off the adaptive frequency in the display settings.
• 🔋 Check if the Ultra Power Saving mode is activated.
• 🐞 Install the SetEdit application** (requires root) and manually set a fixed value.

Problem 3: After the update, the frequency reset

Sometimes, after the MIUI update, the display settings are reset.

1. Go to Settings → Display → Screen refresh rate and select the desired value.
2. If the option is not available, reset settings through Settings → System → Reset settings → Reset all settings (application data will not be deleted).

💡

On some Xiaomi models (e.g. Redmi K50), the screen frequency is tied to the performance mode. To unlock 120Hz, switch to Settings → Battery → Performance Mode.
