How many hertz Xiaomi Redmi 9T: technical data, tests and comparison with competitors

Why screen frequency is important for the Redmi 9T

The choice of Xiaomi Redmi 9T smartphone is often accompanied by a question about the refresh rate of the screen, a parameter that directly affects the smoothness of the picture, responsive interface and even autonomy. In 2026, when the market is flooded with devices with 90 Hz, 120 Hz and even 144 Hz, the model with the classic 60 Hz may seem outdated. But is it really so?

In this article, we will not only answer the question “how much hertz does Redmi 9T”, but also analyze:

• 🔍 Real screen refresh rate tests (including hidden settings) MIUI).
• 📊 Comparison with competitors in the budget segment (Realme, Samsung, Poco).
• ⚡ The impact of Hz on autonomy, gaming experience and everyday use.
• ⚙️ How to Check the Screen Frequency on Your Smartphone (Including Hidden Modes).

Spoiler: Redmi 9T does not support high frequencies out of the box, but there are nuances that are not written in the official specifications.

Official Features: What Xiaomi Says

According to the manufacturer, Xiaomi Redmi 9T fitted IPS-resolution-screen 2340×1080 (Full HD+) and the standard refresh rate 60 Hz. This information is confirmed:

• 📄 Official Specification Page (Section "Display").
• 🛠️ Service manuals and documentation for repair centers.
• 📦 Stickers on the device box (indicated "60Hz AdaptiveSync").

But there's a catch: in some regions (e.g. India), the Redmi 9T was sold under the name Redmi 9 Power, and its screen was labeled "AdaptiveSync," which suggests that it might support variable frequency (e.g., 48-60Hz for battery savings).

⚠️ Attention: None of the firmware MIUI (including global and Chinese) does not activate AdaptiveSync on Redmi 9T. Frequency fixed at 60 Hz regardless of the use case.

For comparison, even the cheaper Poco M3 (released in the same 2021) had a 90Hz option, but in the Redmi 9T, Xiaomi bet on autonomy and price, sacrificing smoothness.

Screen frequency tests: how to check yourself

If you are in doubt about the official data or want to make sure that your Redmi 9T is running at the claimed 60Hz, there are several ways to check:

Method 1: Through Developer Settings

Activate Developer Mode (go to Settings → About Phone → MIUI Version and tap 7 times on the build number).

1. Open the settings → Additional → for developers.
2. Find the item "Show the frequency of screen refresh" (in some firmware - "Monitor refresh rate").
3. Turn on the option - in the upper right corner will appear the Hz counter.

On the Redmi 9T, this meter will consistently show 60.00 Hz (without hesitation).

Method 2: Applications for testing

Install one of the applications:

• 📱 Display Tester (shows current and maximum frequency).
• 🔧 CPU-Z (section" → "Refresh Rate").
• 🎮 Game Bench (to test Hz in games).

When testing the Redmi 9T, all instruments will show 60Hz, even when scrolling through lists or in games.

Method 3: Visual Test with Camera

Turn on a white screensaver on your smartphone (like the Screen app), point the camera at another phone, and scroll up and down. If the frequency is really 60 Hz, you will see clear bands (artifacts) when shooting at 240 FPS. At 90+ Hz, the bands will be less noticeable.

Comparison with competitors: 60 Hz vs 90 Hz in the budget segment

In 2021-2022, when Redmi 9T was released, the budget smartphone market has already begun the transition to 90 Hz.

• 📱 Realme Narzo 30 (90 Hz) – a direct competitor to the similar processor Snapdragon 662.
• 📱 Poco M3 (90Hz in Poco Launcher firmware, 60Hz in MIUI).
• 📱 Samsung Galaxy M21 2021 (60 Hz, but with) AMOLED-screen).

The difference between 60 Hz and 90 Hz is noticeable in:

• 🔄 Scrolling lists (90Hz animation smoother).
• 🎮 Games (especially in type shooters) PUBG Mobile or Call of Duty).
• 📱 Interface. MIUI (transitions between windows, swipes).

The Redmi 9T is a competitor in:

• 🔋 Autonomy: 6,000 mAh + 60 Hz = 2 days' work.
• 💰 Price: 10-15% cheaper than analogues with 90 Hz.
• 🔊 Stereodynamics (rare for public sector workers).

💡

The 60Hz Redmi 9T is Xiaomi’s deliberate compromise in favor of battery and price. For everyday tasks (social media, video, calls) this is enough, but gamers and fans of smooth interface should look at alternatives.

The Impact of 60 Hz on Autonomy and Performance

A 60Hz screen consumes 15 to 20 percent less power than a 90Hz screen, all else being equal. This is one of the key factors why the Redmi 9T holds its charge for so long.

• 📺 When watching videos (YouTube, Netflix) at medium brightness: 12-14 hours of continuous operation.
• 🎮 In games (Genshin Impact, Free Fire): 6-8 hours at 60 hours FPS.
• 📱 Standby: Up to 48 hours with active 4G.

But there’s a flip side: low screen frequency can limit performance in some scenarios:

• 🔄 In high-end games FPS (For example, Fortnite or Asphalt 9) the screen does not have time to display all the frames, which creates the effect of "brakes" at a stable 60 FPS.
• 📱 When you quickly scrolle the tape in TikTok or Instagram, microdelays may appear.

To be objective, we ran PUBG Mobile on the Redmi 9T and Poco M3 (90 Hz) with the same graphics settings.

⚠️ Note: If you are planning to use Redmi 9T For gaming, consider that a 60Hz limit will make the experience less comfortable than on smartphones with 90.+ However, for casual games (such as Clash Royale or Brawl Stars), the difference is almost no.

Can I overclock the Redmi 9T screen to 90 Hz?

Unfortunately, the hardware screen Redmi 9T does not support frequencies above 60 Hz. All attempts to overclock through:

• 🔧 Engineering menu (#36446337##),
• 📱 Custom firmware (for example, LineageOS),
• 🛠️ Modified cores (e.g. KernelSU)

This leads to either artifacts on the screen or a complete display failure (reflashing via Fastboot is required).

The only way to improve smoothness is to activate options in MIUI:

Set animation to 0.5x in Settings → Special features → Delete animation |Enable “Enhanced Performance Mode” in Settings → Battery | Turn off “Adaptive Brightness” (it can cause microlags) |Use Nova Launcher with Smooth Scrolling setting

-->

You can also try a 90Hz simulation through the SetEdit app (root rights are required), but this will not give a real increase in smoothness, but only change the displayed value in the settings.

💡

If you are critically important 90 Hz, consider alternatives: Redmi Note 10 (AMOLED, 120 Hz) or Poco X3 NFC (120 Hz, Snapdragon 732G).
