When it comes to budget smartphones, the Xiaomi Redmi 9A remains one of the most popular choices among price-performance users. However, when buying such a device, many people are faced with the question: how much hertz in the screen of this phone and how does it affect the comfort of use? Hertz (Hz) determine the refresh rate of the screen – a parameter that directly affects the smoothness of the picture, response when scrolling and even battery life.
In this article, we will not only give you an accurate answer to the question of the Redmi 9A screen frequency, but also explain why the manufacturer chose the value that it compares with competitors, and what to do if you think the screen is “braking.” You will also learn whether you can artificially increase the refresh rate (spoiler: no, there are nuances) and how to properly test this parameter on your device. If you are a gamer, like watching videos or just want to see if this smartphone is suitable for you, read on.
Technical characteristics of the screen Xiaomi Redmi 9A: official data
According to the official specification from Xiaomi, Redmi 9A fitted IPS-This is the standard value for budget smartphones of 2020-2021 release, and here's why:
- 📱 Screen resolution: 720 × 1600 pixel (HD+), density ~269 For ppi. 6,53-This is enough for a comfortable viewing of content, but not for over-detailing.
- 🔄 Update frequency: 60 Hz is a fixed value that cannot be changed programmatically, which means that the screen updates the image 60 times per second.
- 🎯 Target audience: the smartphone is positioned as a device for basic tasks - social networks, calls, watching videos 720p, Not for professional gaming or graphics.
It’s important to understand that 60Hz is not a drawback, but a deliberate trade-off: the manufacturer sacrifices smoothness to reduce price, increase battery life and reduce the load on the processor. For comparison, flagship models of the same period (for example, Xiaomi Mi 10) already offered 90 or even 120Hz, but also cost 3-4 times more.
Why 60 Hz: the pros and cons of this choice
The refresh rate of the screen is not just a number in the specs, it directly affects how you interact with your smartphone, let's take a look at the advantages and disadvantages of 60Hz in the Redmi 9A.
| The Benefits of 60 Hz | The disadvantages of 60 Hz |
|---|---|
| ⚡ Battery savings: lower frequency = less load on the processor and graphics chip, which prolongs the working time without recharging. | 🎮 Less smoothness in games: in dynamic shooters (for example, Call of Duty Mobile), the difference between 60 and 90 Hz is noticeable to the naked eye. |
| 💰 Below the price of the device: screens with high refresh rate are more expensive in production. | 📱 Lags when scrolling: with fast scrolling tape in social networks, a “teared” effect can be observed. |
| 🔋 Less heating: Low frequency reduces heat generation, which is important for low-cost processors (Redmi) 9A MediaTek Helio is worth it. G25). | 🎥 Artifacts while watching videos: some videos with high quality FPS (For example, 120 fps) will be brought to 60 Hz, which can cause the picture to shake. |
⚠️ Note: If you are planning to use Redmi 9A For gaming, note that most mobile games are optimized for 60Hz, but in competitive disciplines (e.g., mobile games, PUBG Mobile or Free Fire, the higher frequency may be advantageous because of the smoothness of animation, but for casual games, the difference will be subtle.
💡
To reduce the effect of “teared” scrolling, turn on the developer settings (Settings) → The phone. → Version. MIUI — tap 7 times) option GPU-It's not going to increase the screen frequency, but it's going to make animations a little smoother.
How to check the screen frequency on Xiaomi Redmi 9A: Step-by-step instructions
If you doubt that your Redmi 9A is actually running at 60Hz (for example, after you have firmware or bought a used device), you can check this setting yourself.
- Through Developer Settings: Go to Settings → About Phone → MIUI Version and tap it 7 times to activate Developer Mode. Then go back to the main settings, open Additional → For Developers, and find the Screen Update Frequency. In Redmi 9A, this option will be gray and inactive (as you can’t change it), but it will indicate the current value of 60 Hz.
- With CPU-Z: Download the app from Google Play, open the Device tab, and find the Display Refresh Rate bar, and it will show the current value.

⚠️ Attention: Some users are trying to "accelerate" the screen to 90Hz through an engineering menu or custom firmware. 9A It's not possible -- the hardware doesn't physically support other frequencies -- and this manipulation can cause the display to function in an unstable way or even fail.
Comparison with competitors: 60 Hz vs 90 Hz in the budget segment
To understand how 60Hz is relevant for budget smartphones, compare the Xiaomi Redmi 9A to its main competitors from 2020-2021.

| Poco C3 | 60 | MediaTek Helio G35 | ~9 000 ₽ |
| Xiaomi Redmi 9C | 60 | MediaTek Helio G35 | ~9 000 ₽ |
As can be seen from the table, all budget smartphones in 2020 had a screen with a frequency of 60 Hz. The exception was only some models of 2021 (for example, Redmi 10A or Realme Narzo 30A), where screens with 90 Hz began to appear, but their price was 20-30% higher.
This confirms the thesis: 60 Hz is the standard for the budget segment, and Redmi. 9A If you want a higher frequency, you have to look at models from 10,000 to 12,000. ₽ (for example, Poco X3 NFC 120 Hz).
💡
In 2020, 60 Hz was the norm for smartphones up to 10,000 ₽. Higher frequencies only appeared in models of 12,000. ₽ higher.

Can I increase the screen frequency on Redmi 9A: myths and reality?
On the Internet, you can find “instructions” on how to allegedly overclock the Redmi 9A screen to 90 or even 120 Hz. This is impossible – and here’s why:
- Hardware limitations: The screen matrix physically supports only 60Hz. Even if you change the settings in the firmware, the screen will not be able to update faster.
- Lack of support in drivers: MediaTek Helio G25 does not have drivers to work with other frequencies in this device.
- Risk of damage: Attempts to change frequency through an engineering menu (#4636###) or custom cores can result in artifacts on the screen, overheating or breaking.
The only way to get a higher frequency is to buy another smartphone.
- 📱 Poco X3 NFC (120 Hz, ~15 000 ₽ release-time).
- 📱 Realme 7 (90 Hz, ~14 000 ₽).
- 📱 Redmi Note 10 (90 Hz, ~16 000 ₽).
If you want to improve the smoothness of the Redmi 9A without risk, try:
- ⚡ Disable animations in the developer settings (Window animation scale and transition animation scale set off.).
