How to Increase the Screen Frequency on Xiaomi: 60 to 144 Hz in 5 Minutes

Screen refresh rates are a key parameter that affects the smoothness of the image, the responsiveness of the interface and even the autonomy of the smartphone, POCO Black Shark and others often face the question: how to activate the maximum frequency (90, 120 or 144 Hz), if it does not turn on automatically? MIUI to the engineering menu and ADB-team.

It’s important to understand that not all models support high frequencies. For example, the budget Redmi Note 12 is limited to 90 Hz, while the flagship Xiaomi 14 Ultra or the gaming Black Shark 5 Pro offer up to 144 Hz. We will also explain how to check the current screen frequency, why it can spontaneously decline, and give recommendations for optimizing the balance between performance and battery life.

What Xiaomi models support high screen frequency

Before you try to increase the hertz, make sure your device is technically capable of doing so. Below is a table with popular models and their maximum screen refresh rates (data current for 2026):

If your model is not in the table, check the specifications on the official Xiaomi website or in the Settings app → About Phone → Full Specifications. Please note that even if the device supports 120 Hz, in some regions (for example, in Europe), this feature may be software blocked due to certification.

An important nuance: on devices with LTPO-The frequency is automatically adjusted from 1 to 120 Hz to save charge, manually it can be fixed only through the engineering menu.

How to check the current screen frequency on Xiaomi

Before you increase the hertz, make sure it is really below the maximum. There are several ways to check:

1. Built-in MIUI settings: Go to Settings → Display → Screen refresh rate. This shows the current value (e.g., "90Hz").

If 120Hz is displayed in the settings, but the tests show 60Hz, this is a sign of software restriction (for example, in some applications or when the battery is low).

⚠️ Attention: On devices with MIUI Global (European firmware) frequency can automatically decrease to 60 Hz in power saving mode or at a processor temperature above 45°C. Turn off battery optimization for critical applications in Settings → Battery → Optimizing the battery.

Method 1: Change frequency through standard MIUI settings

The easiest method is to use the built-in system options, which is suitable for most modern Xiaomi, Redmi and POCO devices:

1. Open Settings (the gear icon on the main screen).
2. Go to the Display section.
3. Select the screen refresh rate (on some models it is hidden behind the Additional display settings).
4. Set the desired value: 60 Hz, 90 Hz, 120 Hz or Auto (adaptive mode).

If there is no update frequency, then your model does not support the change of the hertz at the software level, in which case try the methods in the following sections.

Check the device model for compatibility

Charge the battery by at least 50%

Turn off the power saving mode

Make a backup copy of the settings-->

Features of the adaptive mode:

• 🔄 Automatic Switching: The screen reduces the frequency to 60 Hz when watching video, reading or low activity.
• 🔋 Charge savings: 15-20% longer battery life compared to fixed 120 Hz.
• 🎮 Game mode: in games, the frequency can be fixed at the maximum, even if the adaptive mode is enabled.

Method 2: Unlock hidden frequencies through the engineering menu

On some devices (such as the POCO F5 or Redmi K60), the manufacturer hides the maximum frequency in the engineering menu.

1. Open the Phone app and enter the combination: ##4636##.
2. In the menu that opens, select Testing → Display.
3. Find the Refresh Rate and set the maximum value (e.g. 120Hz).
4. Save the settings and restart the device.

Warning: Not all combinations work on newer versions of MIUI. An alternative way to open an engineering menu is through ADB (described below).

On Black Shark devices, to overclock the screen to 144 Hz, you need:

1. Activate Shark Space Mode (Game Launcher).
2. In the launcher settings, select Screen → Update Frequency → 144 Hz.
3. Confirm the warning of increased energy consumption.

⚠️ Note: Black Shark may overheat the Snapdragon 8 Gen 2 processor in games when activated 144Hz. We recommend using additional cooling (cooler or game controller with fan).

Method 3: Using ADB to force high frequency switching on

If the standard methods do not work, you can apply them. ADB-This is a method suitable for advanced users and requires a connection to a PC.

Preparation:

• 🖥️ Install. ADB Fastboot Tools on the computer.
• 📱 Turn on Debugging. USB on a smartphone: Settings → The phone. → Version. MIUI (Click 7 times to become a developer, then Settings → Additionally. → For developers → Debugging by USB.
• 🔌 Connect the device to the PC and confirm a trusted connection.

Commands for frequency change:

adb shell settings put global peak_refresh_rate 120


adb shell settings put global min_refresh_rate 120

Replace 120 with the desired value (e.g., 90 or 60).

To check the current values, use:

adb shell settings get global peak_refresh_rate


adb shell settings get global min_refresh_rate

💡

If the frequency has not changed after the commands are executed, restart the device or enter an additional command to reset the display cache: adb shell cmd display refresh.

Limitations of the method:

• ⚠️ Does not work on devices with a blocked bootloader (bootloader).
• ⚠️ On some models (Redmi Note 11) can only work until the first reboot.
• ⚠️ MIUI Can reset the settings after the system update.

Why the screen frequency spontaneously decreases and how to fix it

Even if you manually set 120 Hz, the system can reduce it to 60 or 90 Hz.

For gaming smartphones Black Shark and POCO F, the problem of "sticking" the frequency at 60 Hz after leaving the game is relevant.

1. Open Shark Space or Game Turbo.
2. Go to Settings → Screen → Reset frequency.
3. Choose Restore after the game.

How to Increase Screen Frequency on Old Xiaomi Models (2019–2021)

Devices before 2022 (Redmi Note 9 Pro, POCO X3, Mi 10T) often have software limitations of 60 Hz, even if the hardware supports 90 or 120 Hz.

Method 1: Castom firmware

• 📱 Install Xiaomi.EU or Pixel Experience – they unlock all frequencies.
• 🔓 You need to unlock the bootloader via the Mi Unlock Tool.
• ⚠️ The risk of loss of warranty and the “brick” of the device.

Method 2: Modified kernels

For some models (for example, POCO F1) there are custom cores with screen acceleration up to 90 Hz.

1. Install TWRP Recovery.
2. Download the kernel (such as FrancoKernel or Kirisakura) with high-frequency support.
3. Squeeze through TWRP (backup in advance!).

⚠️ Note: Redmi Note 10 Pro and similar models with AMOLED-Samsung screens E4 Acceleration to 120 Hz can lead to accelerated degradation of the matrix (pixel burnout.

The effect of high screen frequency on autonomy and performance

Increasing the hertz from 60 to 120 Hz increases the load on the processor and battery. According to XDA Developers tests (2023), the difference in autonomy is:

• 📱 60 Hz: baseline (100% of operating time).
• 📱 90 Hz: 10–15 reduction%.
• 📱 120 Hz: 20–25 reductions%.
• 📱 144 Hz: 30-40% reduction (current for Black Shark).

How to minimize losses:

• 🔋 Use Adaptive Mode instead of a fixed 120Hz.
• 🔄 Turn off high frequency for unnecessary apps through Settings → Annexes → Special rights → High refresh rate.
• 🌙 Activate the Dark Theme -- on AMOLED-This reduces the power consumption by 10-15%.
• 🔌 Use Xiaomi’s original chargers with Quick Charge 4 support+ or HyperCharge.

💡

On devices with a Snapdragon 8 Gen 2 processor (such as the Xiaomi 13T Pro), high screen frequency can lead to trottling (decreased performance) due to overheating. To avoid this, activate the option to limit background processes (maximum 2-3 processes) in the developer settings.

Performance in games:

In most mobile games (like PUBG Mobile or Genshin Impact), the screen frequency syncs with FPS. If your smartphone produces a stable 90 FPS, but the screen runs at 60 Hz, you lose the smoothness.

1. Enable maximum FPS in the game settings (e.g. 90 or 120).
2. Record the screen frequency at maximum through Shark Space or Game Turbo.
3. Use it. GPU-Monitors (e.g. GameBench) to track synchronization.
