How many hertz Xiaomi Redmi Note 12: official data on models

Xiaomi has released several versions of the Redmi Note 12, and the screen refresh rate varies depending on the modification. Here are the exact figures for 2026:

In Russia and CIS countries officially supplied only Redmi Note 12 5G (120 Hz and Redmi Note 12 Pro+ (120Hz with AdaptiveSync. The standard version with 90Hz does not come to our market, but it can be ordered from abroad.

If you buy a smartphone with your hands or through informal channels, be sure to check the modification. For example, the Redmi Note 12 (India) and Redmi Note 12 (Global) may have different screens despite the same name.

How to check the actual screen refresh rate

Even if the specs are 120Hz, the actual frequency may vary due to system settings or application limitations. Here are 3 reliable ways to test Hz on your Redmi Note 12:

Method 1: Through the MIUI settings

The easiest way is to look at the display menu:

1. Open the Settings → Screen.
2. Select the screen refresh rate.
3. If the option is active, you will see the current value (e.g. 120Hz or Auto).

Note: In some firmware, this item may be called Smooth screen or hidden in Additional screen settings.

Method 2: Special applications

For accurate diagnosis, use the utilities:

• 📱 Display Tester (shows real Hz and tests for artifacts).
• 🔧 CPU-Z (In the tab Device displays the frequency of the display).
• 📊 AndroSensor (Real-time Frequency Monitor).

Warning: Some applications may show incorrect data on MIUI Because of the manufacturer's optimizations, use 2-3 utilities at once to be accurate.

Method 3: Testing through the Developer

Activate the developer mode and check the settings:

1. Go to Settings → About phone and tap 7 times on the MIUI version.
2. Back to Settings → Additionally. → For developers.
3. Find the option to Show Update Frequency (if not, your firmware does not support this feature).

Once activated, the current frequency in real time will be displayed in the upper right corner of the screen.

💡

If there is no Hz display option in developer mode, install the Quick Settings app and add the screen monitoring widget to the notification bar.

Can I change the refresh rate to Redmi Note 12?

Yes, but with reservations, depending on the model and firmware, there are different options available:

Official settings of MIUI

AdaptiveSync (Redmi Note 12 Pro)+, Redmi Note 12 5G) choose:

• 🔄 Auto (the system selects frequency from 1 Hz to 120 Hz depending on the content).
• 📱 60 Hz (fixed value for battery savings).
• ⚡ 120 Hz (maximum smoothness but fast discharge).

Path: Settings → Screen. → Screen refresh rate.

Unofficial methods (at your own risk)

For models without AdaptiveSync (e.g., the Redmi Note 12 standard with 90Hz), you can try:

1. ADB-commands for forced inclusion of 120 Hz (does not work on all firmware):
2. Custom firmware (e.g. Pixel Experience or LineageOS), but this voids the warranty.

⚠️ Note: Change the frequency of the update ADB Or an engineering menu can cause sensor malfunctions, overheating or accelerated battery wear. On models without official 120 Hz support (for example, the Redmi Note 12 standard), such experiments are not recommended.

The impact of screen frequency on autonomy: myths and reality

One of the biggest fears of users is, "120 Hz is going to put a lot of battery on the ground." Let's see how that's true.

Autonomy tests

According to DXOMark Laboratory and independent reviews (e.g., TechDroider Channel), the difference in autonomy between 60Hz and 120Hz on the Redmi Note 12 Pro+ form:

• 📱 In video viewing mode: ~15% (120 Hz discharges faster).
• 🎮 In games: ~20-25% (due to increased load on the GPU).
• 📊 In normal use: ~10% (due to AdaptiveSync, which reduces Hz in static images).

How AdaptiveSync saves charge

AdaptiveSync technology (available on Redmi Note 12 Pro)+ and 5G) dynamically adjusts the frequency:

• 📖 Reading text: reduces to 1-10 Hz.
• 🎥 Video viewing: fixes at 24-60 Hz (depending on the FPS content).
• 🎮 Games: Raises to 120Hz.

Due to this, the difference between the Auto and 60 Hz in real use is minimal – only 5-7% according to the GSMArena tests.

⚠️ Note: On models without AdaptiveSync (e.g. Redmi Note 12 standard with 90 Hz), forced on the maximum frequency can reduce the running time by 30-40% when used actively.

💡

AdaptiveSync on Redmi Note 12 Pro+ Reduces energy consumption by 20–25% compared to a fixed 120 Hz, making the difference from 60 Hz almost invisible in everyday tasks.

Comparison with competitors: who offers more Hz?

To gauge how competitive the Redmi Note 12 is in terms of screen frequency, compare it to other budget smartphones from 2023-2026:

As you can see from the table, the Redmi Note 12 Pro+ It offers one of the most flexible AdaptiveSync bands (1-120 Hz), which favorably sets it apart from its competitors. A54 It has a more expensive screen, but the minimum frequency is higher (48 Hz), which is worse for autonomy.

If you compare it to Poco X5 Pro (which is often marketed as a "game" variant of the Redmi Note 12), the latter loses out due to the lack of AdaptiveSync, making it less versatile for everyday use.

Frequent screen frequency problems and their solutions

Redmi Note 12 users sometimes experience Hz-related problems, and here are the typical symptoms and ways to treat them:

Problem 1: The screen flickers at 120Hz

Reasons:

• 🔌 Low-quality charging cable (especially when using Quick Charge).
• 📱 Failure in the display driver after the update MIUI.
• 🔋 Battery discharged below 15% (the system automatically reduces Hz).

Decisions:

1. Switch to 60Hz and check if the flicker is missing.
2. Update your firmware to the latest version (path: Settings) → Updating the system).
3. Reset the screen settings: Settings → Screen. → Reset to factory.

Problem 2: AdaptiveSync is not working

If the Auto option is fixed to one value (for example, always 60 Hz), try:

Turn off the power saving mode|Reboot the phone.|Reset the screen settings|Check the work without a cover (light sensor can be blocked)-->

Problem 3: In games, the frequency falls below 120 Hz

This is normal behavior! Most mobile games are optimized for 60 FPS, So the screen syncs to frame rate to get the game to use 120Hz:

1. Enable the High Performance mode in the game settings.
2. Activate in MIUI Game turbo mode (Settings) → Special facilities → Game settings).
3. Set a limit FPS 120 through the Engineering Menu (requires root rights).

⚠️ Attention: Forced 120Hz on games that don't support this frequency can cause screen tearing and overheating of the processor. Before settings, check if the game supports high-speed play. FPS GameBench website.
