How to increase the hertz on the phone Xiaomi: 5 proven ways

Have you noticed that animations on your Xiaomi don’t work as smoothly as on the flagships of competitors? Or want to gain an advantage in mobile games due to higher screen refresh rates? Increased herzovka (FPS) can dramatically change the experience of using a smartphone — but only if you do it correctly. In this article, we will discuss all the legal and semi-legal methods of overclocking display on Xiaomi, Redmi and POCO devices, from official settings to engineering menus.

It’s important to understand that not all models support dynamic hertz change. For example, the budget Redmi 9A or POCO M3 is physically limited to 60 Hz, while flagships like Xiaomi 14 Ultra or Black Shark 5 Pro can offer up to 144 Hz and above. We’ll show you how to test your device’s current capabilities and maximize them – without the risk of turning your phone into a brick.

1. Check the current screen hertzing

Before trying to increase refresh rates, make sure your display generally supports values above 60Hz. Many users mistakenly think their Redmi Note 10 with 90Hz runs at 120Hz - but that's not the case.

The most reliable way to check:

• 📱 Install the Display Tester app (available on Google Play)
• 🔍 Run the refresh rate test – the program will show the real value in hertz
• 📊 Alternative: Enter the code #4636 in the engineering menu## → Choose Testing → Display

Note that some Xiaomi models automatically reduce the hertz when the battery is low (below 15%), which is protection against overheating, and you can only turn it off through a low battery charge. ADB-Teams (more on that later).

2. Official MIUI settings: what can be changed without risk

Most modern Xiaomi devices (starting with MIUI 12) have a built-in Hertz change option.

1. Open the Settings → Display
2. Select Screen Update Frequency (or Adaptive Frequency on New Models)
3. Available options: 60 Hz, 90 Hz, 120 Hz or Auto (dynamic shift)

One important caveat: on some devices (like the POCO X3 Pro), the option is hidden to activate it:

adb shell settings put global force_fps 1

Once you do this, you'll see a Hertz slider in your settings, but remember, on budget models with a Snapdragon 6xx or Helio Gxx processor, forcing an increase in FPS can cause overheating and reduced battery life.

💡

If after changing the hertz screen began to flicker, return the settings to the factory and check for MIUI updates - it can be a software bug.

3. Acceleration through the engineering menu (for advanced)

Xiaomi's engineering menu allows you to manually adjust display settings, including hertz. Hazard: wrong actions can lead to image artifacts or even the screen fails. Use this method only if you are confident in your actions.

Instructions:

1. Open the phone app and type ##36446337##
2. Go to Display → Display NT36672C (name may vary)
3. Find the Manual DSI Clock or Refresh Rate settings
4. Set the value 10-15% higher than the current one (for example, from 60 Hz to 70 Hz)

⚠️ Warning: If after the changes the screen went out or colored stripes appeared, immediately reset through Hard Reset (clip the Power supply). + Volume up 10 seconds. Some changes to the engineering menu persist even after the reboot!

4.Use of ADB-squadron

For users who are ready to work with Android Debug Bridge (ADB), there are more flexible methods, which is suitable for devices on MIUI 13/14 and requires a connection to a PC.

Steps:

• 🖥️ Install. ADB Tools on the computer
• 📱 Turn on Debugging. USB in the developer settings (Settings) → The phone. → Version. MIUI — tap 7 times)
• 🔌 Connect the phone and execute the command:

adb shell settings put global peak_refresh_rate 120


adb shell settings put global min_refresh_rate 120

These commands force you to set 120 Hz as the minimum and maximum value.

adb shell settings delete global peak_refresh_rate


adb shell settings delete global min_refresh_rate

5 Modified firmware: risks and opportunities

If standard methods don’t work, some users will turn to custom firmware like LineageOS or Pixel Experience, which often offer advanced display settings, including:

• 🎛️ Manual control of hertz with increments of 1 Hz
• 🔄 Dynamic switching depending on the application
• 🛡️ Disabling restrictions MIUI maximum-frequency

However, there are critical disadvantages:

⚠️ Attention: Firmware custom Recovery (TWRP) New Xiaomi models (2023)+ Check the status on the Mi Unlock site before attempting to unlock - some devices require 168 hours of waiting!

6. Optimization of the system for stable operation on high hertzovka

Raising the FPS is only half the battle, and in order for the system to work at high frequencies, you need to:

• 🧹 Disable unnecessary background processes through Settings → Annexes → Auto-start
• ⚡ Activate Performance Mode in Settings → Battery → Regimes
• 🔧 Set a limit FPS Unnecessary applications through Game Turbo
• 🌡️ Monitor the temperature of the processor (use the AIDA64)

For games, we recommend using the GFX Tool, which allows you to force 120 FPS to be installed in supported titles (for example, PUBG Mobile or Call of Duty). However, remember: on weak chipsets (for example, Snapdragon 660), this will lead to severe drawdowns and overheating.

💡

Even on flagship models, 120+Hz constant operation reduces battery life by 20-30%.Use adaptive mode to balance performance and battery.

7. Frequent problems and their solutions

When you try to increase the hertz, users encounter common mistakes, and here's how to fix them:

If after the changes the phone started to brake, reset the cache through recovery:

1. Turn off the device.
2. Press the power + Volume up
3. Choose the Wipe Cache Partition
4. Reboot the phone.
