Your Xiaomi has slowed to open apps, got stuck while scrolling through menus, or suddenly warmed up for no apparent reason? These are typical symptoms of an overloaded system that occur even on flagship models like the Xiaomi 13 Ultra or the likes of the new Xiaomi. POCO F5. The reasons for the brakes lie not only in the “iron”, but also in the features of the firmware MIUI, background processes and energy saving settings.
In this article — 12 Proven ways to speed up Xiaomi, from basic (cache cleaning) to advanced (disable system animations through the Cache Cleanup) ADB). We're not going to tell you to buy a new phone or reset to factory settings, but instead, we're going to figure out how to get things back smooth without losing data. MIUI 14/15 and HyperOS (for models) 2023–2026 year-end).
1.Diagnostics: Why Xiaomi is slowing down?
Before optimizing the system, it is important to understand the source of the brakes. Xiaomi has a built-in monitoring tool – Security → System monitor. This is the display:
- 🔥 Processor – loading cores (if constantly 80-100%, check background tasks).
- 📱 Memory - free/busy RAM (critically if less than 1 GB freely).
- 🔋 Battery - if the temperature is above 40°C, triggers trottling (forced productivity decline).
- 📊 Storage - if occupied >90%, the system starts to "glue».
Typical brake culprits:
- 🤖 Background apps – instant messengers (Telegram, WhatsApp), social networks (TikTok, Instagram) and games (Genshin Impact, PUBG Mobile) consumes up to 30% CPU even in a folded state.
- 🗑️ Cache and garbage – temporary application files (especially browsers) can take up to 5-10 GB.
- 🔄 Auto-updates — MIUI Updates applications and system in the background by default.
- 🛠️ Viruses and malware are rare but are found in pirated APK.
⚠️ Note: If the brakes appeared after the update MIUI, Check the firmware version in Settings → Some assemblies (e.g., telephones, MIUI 14.0.4 for Redmi Note 11) contained memory optimization bugs, in which case only a rollback or waiting for a patch will help.
2.Cache and garbage cleanup: quick effect
The easiest way to speed up Xiaomi is to delete unnecessary temporary files. Unlike factory resets, clearing the cache does not delete personal data (photos, contacts, messages).
Method 1: Integrated cleaning of MIUI
Go to Settings. → Warehouse → Cleaning (or Security) → Cleaning in old versions:
- 🧹 Click “Clean up garbage”** – removes the app cache, residual files and empty folders.
- 📁 Select “Deep Clean”** – scans large files (e.g. uploaded videos to Telegram).
Method 2: Manually cleansing cache for individual applications
Some programs (like Facebook or Google Play Services) accumulate gigabytes of cache to clear it.
- Select an app (like Chrome).
- Press "Storage» → «Clear the cache** (not “Clear the data»!).
⚠️ Note: Do not clear the cache for Google Play Services, Mi Account, and System UI — Also avoid clearing the cache for banking applications (e.g. SberBank Online), as they may require re-authorization.

Method 3: Using third-party utilities
If embedded tools MIUI They can't do it, try it:
Important: After clearing the cache, some apps (like YouTube or Netflix) will take longer to load when they first run – this is normal, as they cache data again.
3. Memory optimization (RAM): How to Free Up Resources
Xiaomi is known for aggressive memory optimization, but sometimes the system gets it wrong and kills the background processes of the wrong applications. RAM manually:
Method 1: Turning off background activity
Many applications continue to work after closing, consuming CPU and RAM. To limit them:
- Go to Settings → Applications → Application Management.
- Choose an app (such as Instagram).
- Press "Battery» → «Background Limitation (or Auto Start in Older Versions) MIUI).
For mass blackout:
- 🔧 Use the settings. → Battery → Power saving mode and select “Limit background processes»**.
- 📵 B Settings → Special facilities → Accelerate the system, turn on the option “Memory cleaning when blocking»**.
Method 2: Configure virtual memory (for devices with a MIUI 13+)
Virtual memory (swap) allows you to use part of the internal storage as a RAM. This is useful for devices with 4-6 GB of RAM (for example, Redmi Note 10 Pro or RAM). POCO X3 Pro).
To include:
- Go to Settings. → About the phone and 7 times click on the "Version" MIUI»** (activates the developer mode).
- Back to Settings → Additionally. → For developers.
- Find the option “Virtual Memory” and turn it on.
- Select the volume (recommended) 1–2 GB 64/128 GB storage).
⚠️ Attention: Virtual memory increases the wear and tear of flash memory (especially on cheap models with eMMC). UFS 2.1/3.0 — Performance gains will be minimal and memory life will be reduced.
4GB or less |6GB|8GB|12GB or more-->
Method 3: Manual release RAM
If the phone suddenly slows down, you can forcibly close the background processes:
- 🔄 Press and hold the Home button** (or swipe up and hold your finger on the recent apps screen), then swipe all apps.
- 📱 Enable "Game Mode"** (Settings) → Special facilities → Game mode – it blocks background processes for maximum performance.
4. Disable animations and visual effects
MIUI She's known for her beautiful but resource-intensive animations, and turning them off will speed up the transitions between screens by 20 to 30%.
Method 1: Through the Developer's Settings
Activate the developer mode (as in the previous section), then:
- Go to Settings → Additional → For developers.
- Find the box “Scale of window animation”, “Scale of transition animation” and “Duration of animation”**.
Method 2: ADB (for advanced users)
If you want to disable animations completely (including system), use the ADB:
adb shell settings put global window_animation_scale 0
adb shell settings put global transition_animation_scale 0
adb shell settings put global animator_duration_scale 0To get back, replace 0 with 1.
Critical information: On some models (Xiaomi) 12T, Redmi K50) shutdown ADB It may cause the interface to fail. MIUI. Before using, make a backup copy!
Method 3: Simplifying wallpaper and so on
Live wallpaper and dark themes with gradients (Super Wallpapers) consume up to 10% CPU. Replace them with:
- 🖼️ Static wallpaper (better in.webp format - they are lighter than.png).
- 🌓 Themes without animations (in the Mi Theme Store, look for themes marked Light»**).
5. Firmware optimization: MIUI vs HyperOS
From 2026, Xiaomi will gradually replace the MIUI It's a new HyperOS shell, if your device is still on the same page. MIUI, Check if it has slowed since the last update.
| Problem. | MIUI 14 | HyperOS (2026) |
|---|---|---|
| Scrolling brakes | Often (due to heavy animations) | Less commonly (optimized rendering) |
| Background processes | Aggressive closure of applications | More flexible management RAM |
| Heating. | High (especially on Snapdragon) 7xx) | Decreased by 10-15 percent |
| Auto-updates | Frequent (once every 1-2 weeks) | Less often (once a month) |
If your device supports HyperOS, but the update hasn’t arrived yet:
- 🔄 Check manually: Settings → The phone. → Updating the system.
- 📥 If the update is available but not installed, download the firmware from the official Xiaomi website and install via the Update. → Three points. → Select a firmware file.
⚠️ Note: Do not install HyperOS on devices older than 2021 (such as the Redmi Note 9 or Mi 10) – there is no official support for them, and custom builds may contain bugs.

6. Advanced methods: for experienced users
If the basics didn't work, try these methods. They take longer, but they give you a noticeable increase in productivity.
Method 1: Disabling unnecessary system applications
MIUI It contains a lot of pre-installed services that can't be removed by standard means, but they can be disabled:
- Activate the Developer Mode (as in Section 3).
List of safe applications to disable:
- 🌐 com.android.browser - Mi Browser (if you use Chrome).
- 📺 com.miui.videoplayer - standard video player.
- 🎵 com.miui.player - Music player.
- 📰 com.miui.weather2 — Weather (if you use Google Weather).
⚠️ Warning: Do not disable com.lbe.security.miui, com.xiaomi.account (Mi Account) and com.google.android.gms (Google Services) – this will lead to critical failures!
Method 2: Change the scheduler CPU
On devices with Snapdragon processors (for example, Xiaomi 12 Pro or Snapdragon processors). POCO F4) You can change the task scheduler for better performance:
- Install Kernel Adiutor (root required).
- Select the “Performance” or “Ondemand” scheduler.
For MediaTek processors (e.g. Redmi Note 12), this method doesn’t work – here optimization depends on the firmware.
Method 3: Transfer applications to SD-map
If internal memory is clogged, some applications can be migrated to microSD (supported on hybrid slot models, such as the Redmi Note). 11S):
- Insert a memory card (UHS-I Class 10 is recommended).
- Go to Settings → Applications → Application Management.
- Select the application and click “Move to” SD-map»**.
Important: Not all applications support portability, and speed with SD-cards are lower than internal memory (especially on cheap cards).
7. Hardware causes of brakes: when to carry in service
If the software methods didn't work, the problem could be the hardware.
- 🔋 Worn-out battery - with a capacity below 70%, trottling (forced performance reduction) is triggered. Check the battery status through Settings → Battery → Battery status or AccuBattery application.
- 🔥 CPU overheating – if the phone is heated above 45°C, CPU Causes: dried thermal paste, dust in the case or damage to the radiator (relevant to Black Shark and other gaming smartphones).
- 💾 Memory problems – if internal storage is (eMMC/UFS) Worn, the speed of reading/write is reduced 2–3 Check it out through AndroBench.
- 📶 Faulty communication module – if brakes occur when connecting to a mobile network or Wi-Fi, the problem may be in the antenna or module RF.
If you suspect a hardware malfunction:
- Make a backup copy of the data.
- Check your phone at a service center (for example, through Mi Service).
- If the device is warranty, do not open it yourself!
💡
Before visiting the service, reset your phone to factory settings (Settings) → The phone. → If the brakes are still there, the problem is definitely the hardware».
8. Alternative firmware: should you switch to caste?
If standard methods don’t help, some users install custom firmware (like LineageOS, Pixel Experience or crDroid).
- ⚡ Higher productivity (no “junk” from the MIUI).
- 🆕 Up-to-date security updates (even for older devices).
- 🎛️ Flexible settings (e.g., scheduler selection) CPU).
Cons:
- ⚠️ Loss of guarantee.
- 📱 Not all functions work (e.g., camera or camera). NFC).
- 🔧 Installation difficulty (requires unlocking the loader).
If you do, follow the official guides to XDA Developers or 4PDA. For beginners, we recommend firmware on the basis AOSP (Pixel Experience, for example, because it is the most stable experience.
💡
Custom firmware can increase performance by 15-30%, but requires technical skills. Start with officially supported devices (listed on LineageOS).
