Enabling high refresh rates not only makes animations smoother, but also reduces game delays, improves interface responsiveness. However, not all versions of the Redmi Note 10S support 90 Hz — this depends on regional firmware, MIUI version and even the batch of the device. In this article, we will look at official activation methods, hidden developer settings, and alternative ways for those who have standard options did not work.

Before you start settings, make sure your smartphone meets the key requirements:

• 📱 Model: Xiaomi Redmi Note 10S (rosemary)
• 🔄 Version. MIUI: 12.5 or later (check in Settings) → The phone)
• 🔋 Battery charge: at least 50% (to avoid failures)
• 📦 Backup: It is recommended to create a backup before changing system parameters

⚠️ Note: In some firmware for European and global markets, the 90Hz option may be blocked at the kernel level, in which case you will need to unlock the bootloader and install custom firmware, which voids the warranty.

1. Check 90Hz support on your Redmi Note 10S

Not all Redmi Note 10S devices are capable of operating at 90Hz, even if the hardware platform allows it, and the reasons are due to software limitations from Xiaomi, which depend on:

• 🌍 Regional firmware (Chinese, global, European, Indian)
• 📦 Versions MIUI (From 12.5.2.0, the option can be hidden)
• 🔧 Manufacturer policies (on budget models often artificially restrict the functionality of the product)

To check if your smartphone supports 90Hz, follow the following steps:

1. Open the Settings app and go to the About Phone section.
2. Click 7 times in a row on the MIUI version bar to activate the developer mode.
3. Go back to the main settings menu and select a new section for developers.
4. Scroll down to the Monitor block and find the screen refresh rate.

If you have 60Hz and 90Hz options on this menu, your device supports overclocking, but if there is only 60Hz or no option at all, you will have to use alternative methods (discuss them below).

2.The official way to enable 90 Hz through settings

If your Redmi Note 10S supports 90Hz at the firmware level, you can activate it in a few steps without further manipulation, which is the safest method and recommended for beginners.

Instructions:

1. Go to Settings → Display.
2. Find the screen refresh rate (may be called Adaptive frequency on new versions of MIUI).
3. Select a value of 90Hz.
4. Confirm the change and restart the device (optional, but recommended).

Once activated, you’ll notice the difference: scroll through the menu smoother, animations faster, and touch delays will decrease. However, note that the increased refresh rate increases battery consumption by 10 to 15 percent. If autonomy is critical to you, use adaptive mode (if available in your firmware).

⚠️ Note: On some firmware after selecting 90Hz, the screen may start flickering or spontaneously return to 60Hz. This indicates a software bug that is solved by resetting the display settings or updating the display settings. MIUI.

3. Hidden methods: activation of 90 Hz via ADB

If the settings menu does not have the 90Hz option, but you are sure that your Redmi Note 10S supports this feature, you can try unlocking it through Android Debug Bridge (ADB), which requires connecting your smartphone to your computer and basic command line knowledge.

What you need:

• 🖥️ A computer with installed Xiaomi drivers and ADB Tools
• 🔌 USB-cable (preferably original)
• 📱 Initiated Debugging Mode USB (developer-side)

Step-by-step:

1. Connect your smartphone to your PC and open the command line (or Terminal on macOS/Linux) in the adb folder.
2. Enter the command to check the connection: Adb devices Make sure your device appears in the list.
3. Run the command to unlock. 90 Hz: adb shell settings put global peak_refresh_rate 90
4. Reboot your smartphone.

After the reboot, check the display settings - the 90Hz point should appear. If that doesn't happen, try an alternative command:

adb shell settings put global oneplus_screen_refresh_rate 1

(Yes, despite the mention of OnePlus, this command sometimes works on Xiaomi devices with Mediatek-processors).

4. Alternative methods: custom firmware and modules Magisk

If none of the above methods work, there are two radical options:

1. Install custom firmware (e.g. Pixel Experience or LineageOS) where 90Hz is enabled by default.
2. Using the Magisk module for forced overclocking of the screen.

Benefits and risks:

To install custom firmware will require:

1. Unlock the bootloader through the Mi Unlock Tool (the process takes up to 7 days).
2. Install TWRP Recovery.
3. Sweep through the selected firmware (see instructions on the XDA Developers or 4PDA forums).

Important: Some versions of MIUI reset the IMEI and serial number after unlocking the bootloader, and can only be restored through a service center.

💡

Before you run the firmware, check the custom build compatibility with your Redmi Note 10S (codename rosemary) model. Version mismatch may cause the sensor or camera to fail.

5 Problems after 90 Hz Included and Solutions

Even if you've managed to activate 90Hz, there can be side effects, and here are the most common ones and ways to eliminate them:

• 🔄 The screen spontaneously switches to 60Hz Cause: Adaptive mode or firmware bug Solution: Turn off adaptive frequency in settings or update MIUI.
• 🔋 Fast battery drain Cause: Increased display power consumption Solution: Use 90Hz only when connected to charging or activate manually.
• 🎮 Lags in games Reason: Not all games are optimized for high frequency.Solution: In the game graphics settings, limit the game's graphics. FPS 60.
• 📱 Heating the device Cause: Increased CPU and display load.Solution: Turn off 90Hz at high temperatures or use a cooling stand.

If after turning on the 90Hz screen began to flicker or artifacts appeared, this may indicate a hardware incompatibility of your display. In this case, go back to 60Hz and do not experiment with firmware - the risk of failure of the matrix is too high.

💡

Before using informal methods (ADB, Magisk, custom firmware) create a full backup of data through Mi Cloud or TWRP. This will save your files in the event of a crash.

6 How to Check That 90Hz Really Works

Not all users can tell by eye that the screen is now updated at 90 Hz. For an accurate check, use one of the methods:

• 📱 Built-in settings Go to Settings → For developers → The refresh rate of the screen. If you've got 90 Hz, and the screen doesn't flicker, it works.
• 🔍 Install Refresh Rate Test or Display Tester from Google Play.They will show the current frequency in real time.
• 🎥 Video test Take a screen on the camera of another smartphone (for example, iPhone) in 240 mode FPS. At 90 Hz, the scroll bands will be smoother than at 60 Hz.
• 🎮 Play benchmark Launch 3DMark The test results will indicate the refresh rate.

If the tests show 60 Hz, despite the settings, it means:

• The firmware ignores your commands (you need to update or stitch again).
• The display driver does not support 90Hz (hardware restriction).
• ADB-The command is not applied (check the rights of the superuser).
