Xiaomi phone is slowing down and hanging: what to do in 2026?

Your Xiaomi is slowing down, apps are late, and animations are jerking? This is a common problem faced by owners of MIUI-based smartphones — even flagship models like the Xiaomi 13 Ultra or Redmi Note 12 Pro+. The reasons can be rooted in software failures and hardware limitations. In this article, we will discuss 10 effective ways to return the phone to performance, from basic actions to radical measures.

First, determine when the lags appeared: after updating the MIUI, installing a new application or mechanical damage (for example, a fall), this will help narrow the range of possible causes. Also pay attention to the temperature of the case - if the phone warms at the slightest load, the problem can be associated with thermothrottle (automatic decrease in performance due to overheating).

Don't rush to reset to factory settings, which is 80 percent more gentle, but if your smartphone is slowing down after you've got a firmware or a virus, you can't do without a lot of hard work, and then you can use step-by-step instructions to take into account the features of Xiaomi 2026.

1.Diagnostics: Why Xiaomi started to slow down?

Before you start optimizing, identify the root of the problem, and here are the key symptoms and their possible causes:

• 🔄 Lags when opening applications → Lack of RAM (RAM) or fragmentation.
• 🐢 Slow interface animation → Failure to work MIUI Launcher or battery savings included.
• 🔥 Overheating and brakes in games → Clogged radiator, worn-out thermal paste or background processes.
• 📉 Hanging after update → Conflict of the new version MIUI customized.
• 🚨 Self-involved reboots → Damaged firmware or faulty battery.

For accurate diagnosis, use the built-in tools:

1. Open Settings → About Phone → System status and check the CPU/GPU boot.
2. Run Security → Optimize – the system will show which applications consume the most resources.
3. Install DevCheck (from Google Play) for detailed analysis of hardware components.

Critical information: If the processor temperature in the System State section exceeds 60°C in idle, this indicates a hardware malfunction - cleaning or replacement of the thermal paste is required.

2.Cache and Memory Cleanup: A Quick Way to Speed Up Xiaomi

The most common reason for brakes is clogged memory. Even if you have Xiaomi with 256GB of storage, the system partition can be overloaded with garbage.

• 🧹 Cleaning the application cache: go to Settings → Annexes → App management, select the “heaviest” app (such as Facebook or TikTok) and click Clear Cache.
• 🗑️ Delete unnecessary files: Use the built-in Cleanup app (in the Tools folder) to find duplicates, temporary files, and remnants of deleted programs.
• 📁 Transfer of data to SD-card: if your model supports memory extension (e.g. Redmi Note 11), move your photos and videos to Settings → Warehouse → Data portability.

For deep cleaning:

1. Open Settings → Memory → Memory Cleanup and select Deep Cleanup.
2. Remove unused items APK-files in the Download folder – they take up space and may conflict with installed applications.
3. Turn off auto-update apps on Google Play if you have limited traffic or slow internet.

⚠️ Note: Do not clean the cache of system applications (e.g. com.miui.home) manually through ADB — This can cause the launcher to crash. MIUI.

3. MIUI Optimization: Disabling Unnecessary Functions

MIUI is known for its abundance of background processes that eat up resources.

It is also recommended that:

• 🔕 Turn off secondary spatial sound in Settings → Sound -- it's loading the processor.
• 🌙 Switch to a dark theme (saves up to 10% charge and reduces screen heating).
• 📶 Shut down search engine Wi-Fi/Bluetooth network-setting.

💡

If after disabling the animation, the interface began to look “sharp”, return the settings to place and instead reduce the animation scale to 0.5x in the developer settings (activated by 7-fold pressing the MIUI version).

4. Firmware Update: When It Helps and When It Harms

MIUI updates can either fix the brakes or cause them. If the lags appeared after the update, try:

1. Reverse to the previous version: Download stable firmware for your model from the official Xiaomi website. Go to Settings → About Phone → System Update → Three dots → Select a firmware file.

Install a global version

CN

Clear the data of the "Update" application

Settings → Applications

⚠️ Attention: Firmware rollback will erase all data unless you use the Fastboot method with the saving of user files!

If the problem is in the MIUI beta, go back to the stable branch:

1 Download the latest stable firmware (e.g., for Redmi Note 10 Pro — "vayu_global_images....").


2. Rename the file to update.zip and place it in the root of memory.




3.Put Volume Up + Power to Enter Recovery.




4. Select Install update.zip and confirm.

5. Resetting: a radical but effective method

If the previous methods didn't work, it's going to be Hard Reset, which will delete all the data, but it will return the phone to factory performance.

1. Backup: Use Settings → Google → Backup to save contacts and settings. Copy photos/video to your PC or cloud (Google Photos, Mi Cloud).
2. Reset: Go to Settings → About Phone → Settings Reset → Erase all data. Enter your password and confirm.

Set up the phone again

Do not restore the backup copy

⚠️ Note: On models with a locked bootloader (for example, Xiaomi) 12T) Recovery resets can lead to a Mi Account authorization requirement, and if you forget your password, unlocking it can take up to 72 hours!

💡

After reset, do not install memory optimizers (such as Clean Master) – they will only worsen performance by conflicting with built-in MIUI mechanisms.

6. Hardware reasons: when to carry in the service

If the software methods did not help, the problem may be in the hardware:

• 🔋 Worn-out battery (capacity) < 70%) → Leads to sudden shutdowns and brakes at low charge. check at AccuBattery.
• 🖥️ Damaged flash memory → Symptoms: frequent errors in file writing, "flying" applications. AIDA64.
• 🌡️ Processor overheating → If the temperature is above 70°C in games, thermopaste replacement is required (Snapdragon 8 Gen 2 is a common problem).
• 🛠️ A trailed train → It appears as a hang when the phone is tilted or vibrating.

The cost of repairs in 2026:

⚠️ Warning: If you notice that the phone only brakes when connected to charging, the problem may be the power supply. Use Xiaomi's original Quick Charge charging - cheap counterparts often cause power controller failures.

7. Alternative firmware: should you switch to caste?

If standard methods did not help, Xiaomi owners often consider custom firmware like LineageOS, Pixel Experience or ArrowOS.

• ⚡ Higher productivity due to lack of “garbage" MIUI.
• 🔄 Regular security updates (relevant to older models, such as the Redmi Note 8 Pro).
• 🎨 Clean Android without advertising and unnecessary services.

Cons and risks:

• 🚫 Loss of warranty (if the phone is under warranty).
• 📱 Non-functioning modules (e.g, NFC or IR-blaster on some firmware).
• 🔧 Difficulty of installation for beginners (requires unlocking the bootloader).

If you do, follow this algorithm:

1. Unlock the bootloader through the Mi Unlock Tool (requires linking Mi Account to the phone).
2. Install TWRP Recovery for your model (instructions on XDA Developers).
3. Download firmware (e.g. Pixel Experience for Poco X3 Pro) and install via TWRP.
