Xiaomi Redmi 9C NFC: how many hertz on the screen is 60 or 90?

If you own a Xiaomi Redmi 9C NFC or are just planning to buy it, you probably care about the refresh rate of the screen (hertz) and you can find conflicting information on the Internet: somewhere they write about 60 Hz, and somewhere there are mentions of 90 Hz. So where is the truth? In this article, we will analyze in detail what the screen frequency of the Redmi 9C NFC actually is, why it can not be higher than 60 Hz, and how this affects the user experience.

Let’s just reveal the main secret: Xiaomi Redmi 9C NFC is equipped with a screen with a refresh rate of 60 Hz. This is the standard value for budget smartphones 2020-2021, which includes this model. However, there are so many myths around the topic of Hertz on smartphone screens that even experienced users sometimes get confused. Next we will explain why 90 Hz on the Redmi 9C NFC is technically impossible, and what to do if you think that the screen is “braking”.

Technical specifications of the screen Redmi 9C NFC: what says the official website

First of all, we turn to the official data. Xiaomi website and the specifications of the Redmi 9C NFC model clearly indicate that the screen has:

• 📱 Diagonal: 6.53 inches (IPS LCD)
• 🔄 Update frequency: 60 Hz
• 🎨 Permission: HD+ (1600 × 720 pixel, 269 PPI)
• 🔦 Brightness: up to 400 nits (typical)

It's important to understand that the refresh rate of the screen is the number of times a picture on a display is updated per second. At 60 Hz, the image is updated 60 times per second, at 90 Hz, 90 times. The higher the value, the smoother the animation and scrolling, but also the more the load on the processor and battery.

The Redmi 9C NFC is a low-end product, and its hardware platform simply isn’t designed for high frequencies.The model uses a MediaTek Helio G35 processor that doesn’t support image output above 60Hz. Even if the screen could physically run at 90Hz, the chipset wouldn’t be able to provide enough performance for smooth operation.

Why do some users think there is a 90Hz NFC on the Redmi 9C?

There are several reasons why rumors of 90Hz on the Redmi 9C NFC are appearing online:

1. Confusion with other models: Redmi’s lineup includes 90Hz devices (like the Redmi Note 10 Pro or POCO X3 NFC), and users sometimes confuse models, especially when it comes to similar names.
2. Developer settings are wrong. There's a Min width option in the Developer menu that changes the scale of the interface, which some people mistake for changing the screen frequency.
3. Marketing tricks of sellers: Unscrupulous sellers may specify non-existent characteristics in descriptions to increase sales.
4. Benchmark errors: Some test programs (such as AIDA64 or CPU-Z) may show incorrect frequency data if the smartphone is modified (such as custom firmware).

If you saw the 90Hz information on the Redmi 9C NFC somewhere, it’s likely either a mistake or a deliberate misrepresentation. Physically, the screen of this model doesn’t support a frequency above 60Hz, and no settings or firmware will change that.

How to check the screen frequency on Redmi 9C NFC

If you are in doubt about the frequency of your screen, you can check it in several ways:

1. Through Developer Settings: Go to Settings → About Phone. Tap 7 times on the MIUI Version to activate Developer Mode. Go back to Settings → Additional → For Developers. Find the Screen Update. If it's not available, your screen is only running at 60Hz.
2. Using applications: 📱 Screen Refresh Rate Tester (Android) 📱 Display Tester (Shows the actual frequency) 📱 AIDA64 (section")
3. Visual test: Run animations on the screen (like scrolling through a long list on Twitter or Telegram). 60 Hz will show a slight "stepping" whereas 90 Hz scroll seems smoother.

Important! On the Redmi 9C NFC, there's no option on the developer menu to change the screen frequency, and if you see it, it's either custom firmware or fake.

Redmi 9C NFC compared to other Xiaomi models by screen frequency

To better understand how 60Hz is relevant for budget smartphones, compare the Redmi 9C NFC with other popular Xiaomi models:

As you can see from the table, 60Hz is the standard for Xiaomi’s budget models. Higher frequencies (90Hz and above) only appear in mid-range and premium devices that use more powerful processors and modern displays (such as AMOLED).

⚠️ If you're asked to overclock the Redmi screen 9C NFC Up to 90 Hz by firmware or modification is a fraud. Physically, the screen and the processor do not support this frequency, and such manipulation can lead to overheating, artifacts on the screen or device failure.

Does 60Hz affect the user experience?

Many users worry that 60 Hz is "little" and the screen will "brake" and in practice it depends on the use cases:

• 📺 Video viewing: Most movies and TV shows are shot at 24 FPS, YouTube content usually goes to 30. FPS 60 FPS. At 60Hz, everything will play without any problems.
• 🎮 Games: Most mobile games (for example, PUBG Mobile, Free Fire, Call of Duty: Mobile - 60 frame rates FPS, So you don't notice the difference from 90 Hz.
• 📱 Daily use: Scrolling on social media, messengers and surfing the web at 60 Hz is comfortable. The difference from 90 Hz is noticed only when you compare it directly.
• 🔍 AR/VR And complex animations: Here, high frequency gives an advantage, but for Redmi. 9C NFC These problems are not relevant due to weak iron.

The main plus of 60 Hz is lower battery consumption. The screen is one of the most energy-consuming components of a smartphone, and the high refresh rate significantly reduces battery life. For a budget phone, where the battery is already not the most capacious (5,000 mAh in the Redmi 9C NFC), this is critical.

💡

If you think the screen is "braking", try to turn off animation in the developer settings (options "Scale of animation windows", "Scale of animation transitions" and "Scale of animation duration" set to 0.5x or turn off completely).

Can I increase the screen frequency on the Redmi 9C NFC?

The short answer is no. The long answer requires explanation.

1. Hardware limitations: The Redmi 9C NFC screen is physically unable to operate at frequencies above 60Hz.
2. CPU limitations: MediaTek Helio G35 does not support image output above 60Hz. Even if the screen could, the chipset would not pull the rendering.
3. Lack of drivers: The MIUI firmware for this model does not contain code for other frequencies.

On the network you can find "instructions" for overclocking the screen through the engineering menu or custom firmware, but:

• ❌ This will not give a real effect – the screen will remain 60 Hz.
• ❌ Risk of damaging the display or disabling the graphics accelerator.
• ❌ Loss of warranty (if the device is still warranty).

If you really want a high screen frequency, consider buying another model, such as:

• 📱 Redmi Note 11 (90 Hz, AMOLED)
• 📱 POCO X4 Pro 5G (120 Hz, AMOLED)
• 📱 Redmi 10 2022 (90 Hz), AdaptiveSync)

💡

If you are buying a smartphone for the sake of high screen frequency, pay attention not only to hertz, but also to the type of matrix (IPS vs AMOLED) and support for AdaptiveSync (automatic frequency switching to save battery).

Frequent Myths About Screen Frequency on Xiaomi

There are many myths surrounding the topic of hertz on Xiaomi smartphone screens.

1. "After updating MIUI The screen frequency has increased to 90 Hz". ❌ Reality: Updates MIUI If newer versions of firmware have 90Hz support, this only applies to models where the screen initially supports it (for example, the Redmi Note 10 Pro).
2. "If you turn on the game mode, the screen frequency increases". ❌ Reality: Game mode MIUI It optimizes performance, but it doesn't change the frequency of the screen. It can increase the frequency. FPS in games (if supported by the processor), but not the Hz display.
3. "Aliexpress sells 90Hz screens for Redmi 9C NFC". ❌ Reality: Replacing the screen with a different frequency model is technically possible, but: Requires soldering of the plumes and firmware drivers. Guaranteedly deprives you of warranties.

"A frequency of 60 Hz is bad for the eyes."

❌ Reality: There is no scientific evidence that 60 Hz is more harmful to vision than 90 Hz. More important than brightness settings, color temperature and the presence of a reading mode (in the graph). MIUI he is).

If you see such claims, always check them through official sources or tests by independent experts (e.g. GSMArena, NotebookCheck, DXOMARK).

⚠️ Attention! Some of the Google Play performance optimizers promise to increase the screen frequency, and these apps are either useless or contain malicious code. None of them can physically change the display.
