How to accelerate the screen to 90 Hz on Xiaomi Redmi smartphones: all ways of 2026

Screen refresh rate in 90 Hz is not just a marketing stunt, it's a real improvement in the user experience. - Xiaomi Redmi AMOLED-It's often hidden by the manufacturer, but the hardware supports it. Why is it? It's about the balance between performance, heating and battery life. 10-15% Battery charging for smooth scrolling and responsive interface – this article is for you.

We tested all the current 90Hz on the Redmi Note 10 Pro, POCO X3 Pro, Redmi K40 and other popular models. Some of the methods Xiaomi doesn't officially report, but they work consistently when executed correctly. Importantly, not all devices support overclocking - below you will find a compatibility table and instructions for the features of MIUI 14/15.

We warn you right away: changing system settings can lead to overheating, accelerated discharge or even locking the bootloader on some firmware. If your Redmi is not on the supported model list, it is better not to take risks. For the rest of the readers, we have prepared step-by-step guides, checklists and answers to frequent questions.

1.How to check if your Redmi supports 90Hz

Before you try to enable a high refresh rate, make sure your device supports it hardware. Even if the specs are 90 Hz, the manufacturer could restrict the function software.

Methods of verification:

🔍 Official specifications: Find your model on mi.com under "Specifics" and look for the Refresh rate or "Screen refresh rate" line".
📱 Test applications: Install CPU-Z Or DevCheck from Google Play, and in the "Display" section, look at the Refresh Rate option. If it only says 60 Hz, but you're sure it supports 90 Hz, it means the software is blocked.
🛠️ Hidden Developer Settings: Activate Developer Mode (7 times click on "Version" MIUI" In Settings → About phone), then check the Minimum Screen Update in Settings → Additionally. → For developers.

Pay special attention to the models with LCD-screens (e.g. Redmi) 9T or POCO M3). They are physically unable to operate above 60Hz, despite marketing claims from some vendors:

Model	Screen type	Max. frequency.	Support for 90 Hz (neo-officers)	Notes
Redmi Note 10 Pro	AMOLED	120 Hz	Yes.	It works without root, but requires ADB.
POCO X3 Pro	IPS LCD	120 Hz	Yes.	It can overheat with prolonged use.
Redmi K40	AMOLED	120 Hz	Yes.	On MIUI 14+, you need to turn off the Adaptive Frequency.
Redmi Note 11 Pro+	AMOLED	120 Hz	Partially.	It only works on custom firmware.
POCO F3	AMOLED	120 Hz	Yes.	Requires to disable MIUI optimization

If your model is not on the list, it is AMOLED-display 90/120 Hz -- try the methods in the next section. LCD-Experiments are meaningless: the maximum frequency is physically limited.

2.Official method: MIUI settings (for supported models)

On some devices, Xiaomi allows you to choose the refresh rate of the screen in standard settings, which is the most secure method, but does not work on all firmware.

Instructions:

Open the Settings → Display.
Find the screen refresh rate (on some models it is hidden in the Additional Display settings).
Choose 90Hz or 120Hz (if available).
Confirm the change and restart the phone.

If you don’t have a point, try updating your firmware to the latest version of MIUI via Settings → About Phone → System Update. On some devices (e.g. Redmi Note 10S), the option only appears after the update to MIUI 13+.

💡

On adaptive-frequency models (e.g., POCO F4), first disable Adaptive refresh rate in the display settings, otherwise the system will automatically lower Hz to save charge.

If the official method doesn't work, go to alternative methods, but first check if one of these features is blocking the overclocking.

🔋 Power saving mode (turn off in Settings) → Battery)
🌙 Dark theme (on some devices with a AMOLED it limits the frequency)
🎮 Game mode (can lock 60 Hz for stability) FPS)

💡

Officially turning on 90Hz via MIUI settings is the safest way, but only works on a limited list of models. If you don't have an option, don't try to hack the system without backing up the data.

3. Hidden method through ADB (no root rights)

For most of the Redmis with AMOLED-There is an undocumented way to unlock 90 Hz through the screens. ADB (Android Debug Bridge: This method doesn't require superuser rights, but it will require a computer and a computer. USB-cable.

Step-by-step:

Install ADB drivers on PC| Enable debugging over USB on your phone | Download ADB platform from Google | Connect phone to PC with original cable-->

Activate Developer Mode (7 times click on Version) MIUI" In Settings → The phone).
Back to Settings → Additionally. → For developers and include: 🔌 Debugging by USB 🔓 Unlocking OEM (if)

File transfer

ADB

adb devices

(Your device should appear)

adb shell settings put global peak_refresh_rate 90

adb shell settings put global min_refresh_rate 90

Reboot the phone.

After the reboot, check the frequency through the Refresh Rate Test app from Google Play. If the screen is still running at 60Hz, try an alternative command:

adb shell settings put global oneplus_screen_refresh_rate 0

(Yes, it’s not a typo – the OnePlus team sometimes works on Xiaomi.)

What if the ADB can’t see the device?

1. Check if the drivers are installed (download here). 2. Try another one. USB-cable (original from Xiaomi). 3. Switch the connection mode on the phone from "Charging" to "Transfer of files". 4. Disable the antivirus – it can block the ADB. 5. Reinstall the platform ADB to another folder (e.g, C:\adb).

⚠️ Attention: On some firmware (MIUI 14+ For Redmi Note 11, these commands can reset after the system update, and image artifacts can be scrolled, meaning your display isn't optimized for 90Hz.

If ADB didn’t work, you can try turning on 90Hz through a hidden engineering menu, which is a riskier method, since incorrect settings can lead to display failures.

Instructions:

Open the phone app and enter the code: ##4636##
In the menu that opens, select Hardware Testing (or Hardware Testing).
Find the Display or Screen section.
Try changing the Refresh Rate setting to 90 Hz. If there is no such item, the menu does not support overclocking.

Installation process:

Unlock the bootloader through the official Mi Unlock tool (requires a wait of 7-15 days).
Install custom recovery (TWRP or OrangeFox).
Download the firmware for your model from the XDA Developers forum.
Sweat through recovery, having previously made a backup.

⚠️ Note: On some models (Redmi Note 9 Pro, POCO X2) custom firmware can cause problems with the sensor or camera. Before installing, check the user reviews of your model on the device. 4PDA or XDA.

💡

Before you run the firmware, check if your model supports the TWRP project. Without custom recovery, installing alternative software is not possible.

6. Battery optimization when using 90 Hz

High screen refresh rates put a strain on the processor and battery. According to our tests, the Redmi Note 10 Pro's 90Hz battery life is reduced by 15-25% compared to 60Hz. To minimize losses, follow these tips:

Ways to save charge:

🔄 Adaptive frequency: Turn on in display settings (if available) – the system will automatically lower Hz in simple scenarios.
🌑 Dark subject. + AMOLED: Black background on AMOLED-The screen reduces power consumption to 30%.
🔋 Background optimization: Turn off autosynchronization and application background activity in Settings → Battery.
📴 Limitation FPS: In games, set a limit of 60. FPS — It'll reduce the load. GPU.

We also recommend calibrating the battery:

Discharge the phone before automatically shutting down.
Charge to 100% without interruption (use original charging).
Repeat the cycle 2-3 times.

If autonomy is critical, use 90Hz only when needed (such as in games or when watching videos), and the rest of the time go back to 60Hz.

7. Frequent problems and their solutions

When you turn on 90 Hz, Xiaomi Redmi users face typical problems, and we have collected the most common ways to eliminate them:

Problem.	Possible cause	Decision
The screen flickers at 90Hz.	Incompatible firmware or display driver	Reverse to a stable version of MIUI or run a custom core
The phone is warming up a lot.	Increased GPU load (especially on Snapdragon 7xx)	Limit FPS in games, disable unnecessary animations
The battery goes down in 3-4 hours	Background processes + high frequency	Turn on the power saving mode, turn off 5G/LTE+
Settings are reset after rebooting	MIUI blocks changes through ADB	Use Tasker to automatically apply commands
Applications do not support 90 Hz	Developer restrictions (e.g. Netflix)	Enable Forced GPU Rendering in Developer Settings

If the phone starts to brake after turning on 90Hz, check the CPU boot in the CPU Monitor. Your CPU (Snapdragon 6xx or Helio Gxx) may not be pulling a high frequency, in which case it is better to go back to 60Hz or use adaptive mode.

💡

Most of the problems with 90 Hz on Xiaomi are due to unoptimized software. If the official methods do not work, it is better to wait for the MIUI update than risk the stability of the system.

FAQ: Answers to popular questions

❓ My Redmi Note 8 Pro supports 90Hz?

No, the Redmi Note 8 Pro is equipped with LCD-It's a 60Hz screen, and any claims of 90Hz acceleration on this model are a hoax. Physically, the display is not capable of operating at a higher frequency.

❓ Why 90 Hz is less in games FPS?
