Have you ever looked at the “Security” section? → Speed boost in global firmware) on your smartphone Xiaomi, Redmi or POCO And you see the list of "fixed apps" there? This mysterious feature raises a lot of questions: why does the system "fix" programs, how does it affect the speed of the phone, and can you turn off unnecessary elements without harming the device.
In this article, we will take a closer look at how fixed applications work, explain how they differ from normal background processes, and show you how to manage this list correctly to optimize Xiaomi performance without loss of functionality. You will also learn which applications should never be unplugged, even if they seem redundant, and how to avoid common errors when setting up acceleration.
The material will be useful as beginners who are just beginning to understand the subtleties MIUI, And it's also for the power users who want to make the most of their device. MIUI 14/15 New models, including Xiaomi 14, Redmi Note 13, POCO F6), But the principles of the function remain unchanged for older gadgets.
What are the fixed applications in the “Accelerator” Xiaomi
Locked applications are a special list of programs that the system MIUI Protects against automated memory cleaning (RAM) When you activate this option for the app, the Xiaomi smartphone starts treating it as a critical process, even if you haven’t used it in a long time.
By default, this list includes:
- 📱 System Services (Google Play Services, MIUI System)
- 💬 Messengers (WhatsApp, Telegram, WeChat)
- 📞 Calling applications (Truecaller, Mi Dialer)
- 🎵 Music Players (Spotify, Mi Music)
- 📊 Synchronization services (Mi Cloud, Google Drive)
The main purpose of the feature is to prevent a sudden shutdown of background processes that are important to the user. For example, if you fix Telegram, even if you don’t have enough RAM, the system will not shut it down completely, but only stop working, while maintaining the ability to instantly receive notifications of new messages.
How fixed applications affect productivity
Many users mistakenly believe that the more apps are fixed, the faster the smartphone works, in fact, the opposite effect: each fixed process reserves a portion of RAM, reducing the resources available for active tasks. This is especially true on 4-6 GB devices. RAM (Like Redmi. 10A or POCO M5).
Let us consider the key implications:
| Script | Impact on productivity | Recommendation |
|---|---|---|
| Fixed 5+ applications | ⚠️ Noticeable lags when switching between tasks, new programs open longer | Leave 2-3 of the most important (messengers, navigator) |
| Only system services are provided | ✅ Optimal balance: Memory is cleaned efficiently, critical processes are not killed | The perfect configuration for most users |
| Fixed games (PUBG, Genshin Impact) | ❌ Games are closed when folded, but they are occupied. RAM background | Use the Game Turbo instead of the turbo |
| Social networks are fixed (Facebook, Instagram) | 🔄 Notifications come faster, but battery consumption grows by 10-15% | Only if push notifications are critical |
Important nuance: on the flagships with 8+ GB RAM (For example, Xiaomi 13 Ultra or Black Shark 6 Pro, the effect of attaching applications is minimal - the system already knows how to correctly manage memory. A2, POCO C50) Every extra fixed process can be worth waiting a few seconds when opening a camera or gallery.
💡
To check the actual consumption RAM, Go to Settings. → The phone. → Memory and see the real-time usage schedule. If the free memory is consistently under 20%, you should review the list of fixed applications.
Where to find and how to manage fixed applications
The interface for managing fixed applications differs depending on the version MIUI And regional firmware. We're going to look at two of the most common options:
For global/European firmware (MIUI 14/15):
- Open the Security app (shield icon).
- Go to Speed Boost (or Optimize in some versions).
- Slip on the Locked apps.
- Turn on/off switches next to the desired applications.
For Chinese firmware (or older versions) MIUI):
- Launch Security.
- Choose Acceleration.
- Click on the Fixed Apps.
- Manage the list through the checkmarks.
In some models (POCO F4, Xiaomi 12T) The path may look like this: Settings → Annexes → Application management → If you can't find a section, search by settings (the magnifier icon in the upper right corner).

What applications can (and should) be removed
Most Xiaomi users never edit the list of fixed applications, leaving everything that the default system added there, which leads to inefficient resource consumption, especially on devices with low RAM.
- 🎮 Games: PUBG Mobile, Call of Duty, Genshin Impact – fixing will not help to keep progress when folding, but will eat RAM. Use Game Turbo to optimize your game.
- 📺 Streaming services: YouTube, Netflix, Twitch – they don’t need background work when you’re not using them.
- 🛒 Shops: AliExpress, Amazon, Shopee - discount notices are not worth losing performance.
- 📰 News apps: Google News, YandexZen – their background activity only consumes battery.
- 📊 Fitness trackers: Mi Fit, Google Fit – enough one-time synchronization, constant fixing is not necessary.
A critical mistake many users make is to leave apps that are long gone but don't delete them completely, for example, if you stop playing Clash of Clans but the app stays on the fastened list, it will take up memory even when you launch the camera or photo editor.
What happens if you unplug system applications?
Dangerous Myths About Fixed Applications
There are many misconceptions surrounding the app attachment function that lead to incorrect settings and a deterioration in user experience.
⚠️ Warning: If you see the advice “fix all applications for maximum performance” – before you or outdated instructions (current for the use of the software). MIUI 8-9), or outright misinformation. Modern versions of firmware can prioritize processes themselves.
Myth 1: “Accretion speeds up application launches”
Reality: The app only starts faster if it has already been downloaded to the app RAM. If there's not enough memory, the system will still unload it despite the fixing.
Myth 2: “Apps that are fastened don’t consume batteries”
Reality: Background processes consume energy even when they are “fixed”; for example, Facebook can use up to 5-7% of its charge per hour in the background, whether it is fixed or not.
Myth 3: “Accumulation is necessary for the correct operation of widgets”
Reality: Widgets work through a separate mechanism (App Widgets Service), and their update is independent of the main application securing, except for the weather widgets (Mi Weather), which do require background synchronization.
Myth 4: “Once unplugged, the app will stop updating.”
Reality: App updates from Google Play or Mi App Store are made through separate services (Download Manager) and are not affected by attachment.
How to Optimize the List of Fixed Applications
To achieve the perfect balance between performance and functionality, follow this algorithm:
- Current list audit: Remove all apps you don't use daily, leave only messaging apps (WhatsApp, Telegram) and critical services (Google Play Services).
- Testing: After the changes, check if notifications are coming in messengers and if sync is working (for example, Mi Cloud or Google Photos).
- Monitoring RAM: Use the built-in memory monitor (Settings) → The phone. → Memory or third-party utilities (Simple System Monitor) to track free RAM.
- Exceptions for games: If you play heavy projects (Genshin Impact, Honkai: Star Rail), turn off their fixing and use Game Turbo in the settings.
- Regular cleaning: Revisit the list once a month – it is possible that some apps have become irrelevant (for example, seasonal games or promotions).
For advanced users: if you use Xiaomi.eu or custom firmware, you can turn off the fastening of all applications through ADB:
adb shell pm disable-user --user 0 com.miui.securitycenter
adb shell pm disable-user --user 0 com.miui.guardprovider⚠️ Warning: This will completely shut down the Security Center, which can lead to notification and update issues!
💡
The optimal list of fixed applications for most users: messengers (1-2 pcs.), navigator (if you use regularly), system synchronization services. All the rest is extra ballast.
Frequent problems and their solutions
Incorrect configuration of fixed applications can lead to various failures. Let's consider typical situations and ways to fix them:
| Problem. | Probable cause | Decision |
|---|---|---|
| Notices do not arrive in the Telegram/WhatsApp | The application is unplugged or killed by the system | Secure the messenger and check the battery settings (No restrictions) |
| The phone is slowing down after the changes. | There are too many apps (especially games) attached. | Leave the 2-3 most important ones, restart the device |
| Weather/hour widgets not updated | The system service Mi Weather is unavailable | Return Mi Weather to the list of pinned or use a third-party widget |
| The battery goes down fast. | Resource-intensive applications (Facebook, Instagram) are fixed | Unplug social networks and limit their background activity in the battery settings |
| The game flies out when folded up. | Fixing doesn’t help – you need to optimize through Game Turbo | Unplug the game and add it to Settings → Game Turbo |
If after all the manipulations, problems persist, try resetting the Security Center settings:
- Go to Settings → Applications → Application Management.
- Find Security (com.miui.securitycenter).
- Press Warehouse. → Clear the data.
- Reboot the phone.
⚠️ Warning: Resetting Security Center will return all acceleration settings to factory, including the list of fixed applications.
