Why Xiaomi Redmi is slowing down and how to fix it: the full guide 2026

Your Xiaomi Redmi suddenly started hanging, apps are opening late and animations are twitching? is a common problem faced by owners as budget (Redmi). 9A, Redmi 10C), The same goes for the Redmi Note 12 Pro.+, Redmi K60). The causes of brakes can lie in filled memory, outdated firmware, background processes or even hardware malfunctions.

In this article, we will look at all possible causes of slowdown and offer step-by-step solutions, from basic (cache cleaning) to advanced (fastboot flashing), you will learn how to diagnose a problem, which settings to optimize, and when to contact the service center. We will pay special attention to the models of 2020-2023, where the brakes are often associated with aggressive policy. MIUI resource management.

Before you start fixing, answer two questions: 1. The brakes appeared after the update. MIUI Or install a new app? 2. Do you notice the body overheating while working?

This will help narrow down the range of possible causes.

1. Diagnosis: how to determine the cause of brakes

Before you clean or dump a smartphone, it is important to understand what exactly causes lag. MIUI There are built-in diagnostic tools, as well as third-party utilities.

Open the Settings. → The phone. → Version. MIUI and tap 5 times on the kernel (or build number on new versions) this activates the developer mode. → Additionally. → For developers and include:

• 📊 Process statistics (show which applications are loaded) CPU)
• 🔍 Do not save operations (will help identify background tasks)
• 📉 GPU-acceleration (displays the load of the GPU)

For deep analysis, use the application CPU Monitor (real-time loading of cores) or AccuBattery (battery consumption and heating). CPU It is over 70% for no apparent reason and the temperature is above 45.°C – the problem may be hardware acceleration or overheating of the chipset.

System Cleanup: Cache, Garbage and Unnecessary Files

The most common reason for brakes is a lost memory, even if you have a Redmi with a scalp. 128 GB of the drive, system partition (/data) It can be full of cache and temporary files:

Step 1. Clean up the app cache

• 🧹 Go to Settings. → Annexes → Application management.
• 🔍 Sort by size and choose the heaviest (usually YouTube, Chrome, MIUI Gallery).
• 🗑️ Press Warehouse. → Clear the cache.

Step 2: Systemic debris disposal

Use the built-in Cleanup utility (the broom icon in the Security menu).

• 📁 Temporary files APK
• 🗃️ Logs and dumps of the system
• 🖼️ Sketch and miniature

Step. 3. Cleaning up the section /cache recover

If the smartphone is slowing down even after cleaning, try erasing the recovery cache:

1. Turn off the phone.
2. Press Power + Volume up until the Mi logo appears.
3. Choose Wipe & Reset → Wipe Cache (control - volume buttons, confirmation - power).

Backup of important data|Charge your phone at least 50 times%|Close all background applications|Disable Auto-Update Applications-->

3. MIUI Optimization: Disabling Unnecessary Functions

MIUI It's known for its heavy interface and a lot of background processes, and many of them can be turned off without losing functionality.

What can be safely turned off:

Disabling the “heavy” services Xiaomi:

• 🚫 Second Space (Duplicates Desktop and Loads) RAM)

adb shell pm disable-user --user 0 com.miui.systemAdSolution

This will remove the module responsible for displaying banners in settings and applications.-->

4. Firmware update: when it helps and when it hurts

Paradox: Sometimes the brakes appear after the update MIUI, And sometimes it's because he's not there.

Case 1: Outdated firmware

If your Redmi hasn’t been updated in a long time, check the current version in Settings. → The phone. → System update: For models older than 2 years (Redmi 8, Redmi Note 9), the latest firmware can be found at en.miui.com.

Case 2: Raw Update

If the brakes appeared immediately after the update, the reasons may be:

Solution: roll back to the previous version via Fastboot or wait for the patch.

5.Reset to factory settings: when it really needs to

If all the previous methods didn't work, you get a hard reset, and it's a radical solution, but it's guaranteed to remove:

• 🗄️ Accumulated errors in system files
• 🧩 Conflicting user settings
• 🦠 Viruses and malware (if any)

How to Reset Redmi Right:

💡

After reset, don't install all the apps at once! Add them one at a time, and you can see the performance, and this will help you identify the "braking" software.

What if the reset didn't help?

If the brakes remain even after reset, the problem may be:

• 🔋 Worn-out battery (at a charge below 20%, the chipset limits performance).
• 🔥 CPU overheating (check the heat paste – relevant for models over 3 years old).
• 🛠️ Hardware malfunction (damage to flash memory or RAM).

6 Advanced methods: firmware, cores and modifications

If you're willing to go beyond standard settings, consider these options. They require technical skills and may be unwarranted!

Option 1: Installation of custom firmware

Firmware like LineageOS, Pixel Experience or Xiaomi.eu are not “heavier" MIUI offer:

• ⚡ Faster work due to the lack of background services Xiaomi.

Instructions for installing Xiaomi.eu:

1. Unlock the bootloader through the Mi Unlock Tool (requires an account binding Mi).
2. Install TWRP Recovery for your model.
3. Download the firmware from Xiaomi.eu and run through TWRP.

Option 2: Optimization of the kernel

Using applications like Kernel Adiutor or FrancoKernel, you can:

• 🔧 Change the governor CPU (Ondemand or interactive is recommended).
• 📈 Disable "sleeping" cores at low load.
• 🔋 Optimize battery consumption without losing performance.

#4636## → Battery Information → Select Performance

This will temporarily overclock the processor, but increase battery consumption.-->

7. Hardware problems: when to carry in the service

If the software didn't work, the brakes could be caused by hardware.

How do I check flash memory?

Install the app A1 SD Bench and run a reading/write test if the speed is lower:

• 100 MB/s for eMMC 5.1 (Redmi 9, Redmi Note 8)
• 300 MB/s UFS 2.1/2.2 (Redmi Note 10 Pro, Redmi K40),

The memory is worn out and needs to be replaced.

💡

If the smartphone is slowing only in specific applications (for example, in the PUBG Mobile or Genshin Impact, the problem may be in the processor's trottling due to overheating. AIDA64 play-play.

8. Alternative solutions: if nothing helps

When all the methods have been tried and Redmi is still slowing down, consider these options:

1. Use of lightweight firmware

For weak models (Redmi) 8A, Redmi 9C) There are "light" versions. MIUI, for example:

• 🪶 MIUI Lite (stripped interface without animations)
• 🐧 MIUI Optimized (from the community, with Xiaomi remote services)

2. Replacement with a more productive model

If your Redmi is older than 3-4 years (Redmi 6, Redmi Note 7), it may not be enough resources for modern tasks. In 2026, the minimum requirements for comfortable operation are:

• 📱 4/64 GB of operational and built-in memory,
• 🔧 The chipset is weaker than the Snapdragon 660 or Helio. G80,
• 🔄 Support MIUI 14 or newer.

3.Switching to another launcher

Interface. MIUI can be replaced by a lighter:

• 🏠 Nova Launcher (flexible settings, no extra animations)
• ⚡ Lawnchair (minimalistic, gesture-enabled)
• 🎨 Hyperion Launcher (optimized for weak devices)

adb shell pm disable-user --user 0 com.miui.home

This will free up to 200-300 MB of RAM!-->
