How to Make Xiaomi Phone Run Faster: The Complete Guide

Why Xiaomi Smartphone Begins to Brake and How to Fix It

Even Xiaomi’s most powerful smartphones are slowing down over time, with apps opening longer, animations twitching, and the system reacting with a delay, not only due to the natural aging of iron, but also due to the features of MIUI firmware, which actively uses background processes and caching. In this article, we will discuss 15 proven ways to restore your Redmi, Poco or Mi to its former agility, from basic to advanced.

The main reasons for slowing down are overloaded cache, unnecessary background applications, fragmented memory and unoptimized system settings. For example, the RAM Boost feature in MIUI can both speed up and slow down a smartphone, it all depends on the configuration. We will not advise “just reset to factory settings” (this is an extreme case), but show you how to increase performance by 30-50% without losing data.

1.Cache and garbage cleanup: the first step to speeding up

App cache and system debris are the main brakes for Xiaomi. Even if you have 128 GB of memory, a cache clogged can reduce speed by 20-30%.

• 🧹 Go to Settings. → Annexes → Clean up and press "Clean up the garbage".
• 🔍 In the Deep Cleanup section, select App Cache and remove it for all programs.
• 📊 Check the Storage section – here you can see which apps take up the most space.

For more thorough cleaning, use SD Maid (from Google Play) or Files by Google. These apps find residual files after uninstallation of programs and temporary data that MIUI does not delete automatically. For example, after updating MIUI 14, many users notice that the system leaves up to 1-2 GB of unnecessary files in the /data/miui folder.

💡

If, after cleaning the cache, the applications have been loading longer on the first run, that's OK. The cache will recover automatically, but without any extra debris.

2. Optimization of autoboot and background processes

MIUI aggressively keeps apps in memory even when you're not using them, and it consumes RAM and CPU resources to turn off autoboot:

1. Go to Settings → Applications → Application Management.
2. Select an app (such as Facebook or TikTok) and click AutoStart.
3. Turn off autostart permissions, background activity, and push notifications.

For mass shutdown, use Greenify (requires root rights on new MIUI versions) or built-in Performance Mode:

• 🚀 Go to Settings. → Additionally. → Performance mode.
• 🔋 Select “charge savings” or “balanced” – this will limit background activity.
• ⚡ Enable the option to "Limit background processes" (available on the MIUI 13+).

3. Customization of animation and visual effects

MIUI is known for its beautiful yet resource-intensive animations, which can speed up the interface by 15-20%.

1. Activate Developer Mode: Go to Settings → About Phone and click on MIUI Version 7 times.
2. Back to Settings → Additionally. → For developers.
3. Find sections: The scale of window animation → Choose Off. Or 0.5x. Scale of transition animation → Off, the duration of the animator → Off..

Also, turn off unnecessary visual effects:

• 🌈 B Settings → Display. → Select "Standard" instead of "Saturated".
• 🔄 Turn off Smooth Transitions in Settings → Special facilities → Improved visibility.
• 🎨 In the themes. MIUI Select a minimalist theme (e.g., "Simplicity").

4.Memory optimization: RAM and storage

Xiaomi is actively using RAM Expansion technology, but on weak smartphones (for example, Redmi 9A or Poco M3) this can lead to the opposite effect.

• 📱 Go to Settings. → The phone. → Memory.
• 🔄 If "Extension" is included RAM", Turn it off or reduce the volume to 1 GB.
• 🧠 Turn on the "Cleaning" option. RAM" when blocking the screen (available in Settings) → Battery and productivity).

For devices with 6 GB of RAM and less, we recommend:

💡

On smartphones with 4 GB of RAM, turning off RAM expansion can increase the speed of work by 25-30% by reducing delays when switching between applications.

5. Updating firmware and kernel: when it helps

The slowdown may be due to outdated firmware or bugs in the current version of MIUI. Check the relevance of the software:

1. Go to Settings → About the phone → System update.
2. If you have an update, install it. For stable operation, choose a stable branch (not beta!).
3. After the update, perform a cache reset: press Volume up + Power when downloading, select Wipe Cache.

For advanced users, if your Xiaomi supports custom firmware (like LineageOS or Pixel Experience), installing it can speed up your work significantly, but it requires unlocking the bootloader and may be insecure.

6.Reset to factory settings: a last resort

If all the previous methods didn't work, it's hard reset, which is a radical way, but it returns the speed to the factory.

• 📱 Make a backup through Settings → Google → Backup or Mi Cloud Backup.
• 🔐 Take a picture or login/passwords from your accounts.
• 📁 Save photos and videos to your PC or cloud.

For discharge:

1. Go to Settings → About the phone → Reset settings.
2. Select "Erase all data."
3. After the reboot, set your phone up as new (don’t restore the MIUI backup – it may contain old bugs!).

💡

If the phone is still braking after reset, check battery health at Settings → Battery → Battery status. A worn-out battery (capacity < 80%) can artificially limit performance.

Hardware methods: if the problem is in the "iron"

Sometimes the slowdown is due to the physical wear of the components.

• 🔋 Battery: If the battery capacity is below 70%, the system starts trottling.
• 💾 Memory. eMMC/UFS: on budget models (Redmi) 8A, Poco C3) Cheap memory degrades over time. Check the speed with AndroBench if the record is below. 50 MB/s, it's time to think about replacing.
• 🌡️ Overheating: If the processor is warmer than 60°C, it automatically reduces the frequencies. Clean the phone of dust (especially the charging connector) and replace the thermopaste (in the service).

For diagnosis, use:

• 📊 CPU Throttling Test (checks processor trottling).
• 🔋 AccuBattery (Battery Health Monitor).
• 💾 AIDA64 (Tests the speed of memory and processor).
