Xiaomi Redmi 12: how many hertz does the screen have?

Xiaomi Redmi 12 became one of the most talked-about budget devices of 2023, and its screen played a role in this. Users are actively wondering: how much hertz does the display of this model support? The answer to this question is important not only for gamers, but also for those who appreciate the smooth interface and comfort when scrolling content. In this article, we will understand what the default refresh rate of the screen is in Redmi 12, how to check it, and whether it can be changed in the settings.

It is worth noting that the refresh rate of the screen (measured in hertz, Hz) directly affects the perception of the picture: the higher the value, the smoother the animation and less blur in dynamic scenes. However, not all Xiaomi models in the budget segment boast high performance. Next, we will analyze the official specifications, check real tests and give recommendations for optimizing the display.

Redmi 12 Screen Specifications: What Does Xiaomi Say?

According to the manufacturer, Xiaomi Redmi 12 fitted 6,79-inch IPS-resolution-screen FHD+ (2460×1080) However, the official specifications on the Xiaomi website and in the documentation, the update frequency is indicated ambiguously:

• 📊 Basic frequency: 60 Hz (standard for budget models).
• ⚡ Dynamic frequency: up to 90 Hz (in some regions and firmware).
• 🔍 AdaptiveSync: Automatic switching between 30Hz, 60Hz and 90Hz depending on content.

It is important to understand that the actual frequency may vary depending on the firmware version (MIUI 14 or later) and the region of sale. For example, in the European and Indian versions of Redmi 12, support for 90 Hz is often found, whereas in some Asian versions the screen is limited to 60 Hz. This is due to the optimization of power consumption and cost of the device for different markets.

How to check the real screen frequency on Redmi 12?

To know exactly how much hertz your Redmi 12 is giving out, you can use a few methods. The first and easiest one is to go to the system settings:

1. Open the Settings → Display.
2. Find the screen refresh rate (in some firmware it may be called AdaptiveSync or Smooth screen).
3. If the option is available, you’ll see a switch between 60Hz and 90Hz (or Auto).

If there is no such item on the menu, it may mean that your version of Redmi 12 does not support 90Hz. In this case, a third-party application, such as CPU-Z or Display Tester (available on Google Play), will help.

💡

If you don’t have a frequency change option in your settings, try updating your firmware to the latest version of MIUI. Sometimes the manufacturer adds 90Hz support in subsequent updates.

Can I turn 90Hz on Redmi 12 if they are not available by default?

Many users are faced with a situation where the Redmi 12 settings do not have the option to switch to 90 Hz, although the characteristics of the device it is specified.

• 📦 Regional restrictions: Some firmware versions block the feature to save energy.
• 🔧 Hardware differences: not all Redmi 12 batches are equipped with 90-hertz panels.
• 🛠️ Software limitations: Xiaomi can artificially disable the function on budget models.

In some cases, you can unlock 90 Hz by:

1. Manually enable via the engineering menu: ##4636## In the menu that opens, find the Display section and check the available options.
2. Custom firmware installations: for example, Pixel Experience or LineageOS (requires unlocking the bootloader).
3. Uses ADB-Adb shell settings put global peak_refresh_rate 90 Attention: This method requires knowledge and can lead to unstable operation of the system.

Redmi 12 Comparisons to Competitors: Who Offers More Hertz?

In the budget segment (up to 15 000) ₽) Xiaomi Redmi 12 competes with models from Realme, Samsung and Motorola.Let's compare the refresh rate of the screen in popular alternatives:

As you can see from the table, Redmi 12 is not the leader in refresh rates, but it offers AdaptiveSync, which automatically adjusts hertz to content. This saves battery power without losing smoothness in games or scrolling through social media feeds. However, if you are critically important 120 Hz, it is worth considering the POCO M6 Pro or the Realme Narzo 60.

💡

AdaptiveSync in Redmi 12 is a trade-off between smoothness and autonomy: In games, the screen can accelerate to 90 Hz, and when reading, it can drop to 30 Hz to save energy.

The impact of screen frequency on the autonomy of Redmi 12

One of the key questions is, how much faster does a battery run down when using 90 Hz instead of 60 Hz? Tests conducted by enthusiasts on the 4PDA and XDA-Developers forums show that the difference can be as high as 15-20% in active use.

• 🎮 Games: at 90 Hz, autonomy decreases by 1.5-2 hours (from 6 to 4-4.5 hours).
• 📱 Social networks / web: the difference is less noticeable - about 10-15% (from 8 to 7 hours).
• 🎥 Video: Frequency is almost unaffected, as most videos have a fixed FPS (24-60 personnel/s).

To optimize autonomy, it is recommended:

If you don't notice the difference between 60Hz and 90Hz in everyday tasks, you'd better keep the standard settings, but gamers and fans of smooth animation should experiment with AdaptiveSync.

Frequent Redmi 12 screen issues and their solutions

Some Redmi 12 users are experiencing update frequency issues, and let’s look at the typical cases and how to fix them:

⚠️ Warning: If after updating the firmware screen began to flicker or spontaneously switch hertz, try resetting the display settings to factory (Settings) → System system → Resetting settings → Resetting display settings).

• 🔄 The screen itself switches between 60 and 90Hz: This is the normal work of AdaptiveSync. To turn off, manually lock the frequency in the display settings.
• 🖥️ When connected to a PC or TV, the frequency is reset: The problem may be in the cable or transmission protocol (e.g., the transmission protocol, MHL It doesn't support 90Hz. Try another cable or port.
• 🔋 Fast battery drain at 90Hz: Check which apps are actively using the screen (c Settings) → Battery → Battery use.Perhaps background processes are preventing AdaptiveSync from working properly.

If the problem is not solved, you should contact the Xiaomi service center, especially if the screen has begun to artefact (bars appear, broken pixels) or completely shut down.
