App Assignment on Xiaomi: A Complete Guide to Setup and Use

Have you ever experienced a situation where you accidentally shut down an important application on Xiaomi and lost unsaved data? or notice that background programs suddenly stop working after cleaning up. RAM? Function of fixing applications in firmware MIUI And HyperOS is the solution to these problems, and it allows you to attach selected programs to RAM, preventing them from automatically closing the system?

In this article, we will understand what is the fixation of applications on Xiaomi, Redmi and smartphones. POCO, How it differs from the standard addition to your favorites, and how to properly configure this feature for optimal device performance, you will also learn about hidden features that the manufacturer does not always advertise, and how to circumvent the typical system limitations. We will pay special attention to the differences between MIUI 12/13/14 And the new HyperOS, where the logic of the function was reworked.

What is the attachment of applications and why it is necessary

App pinning is a mechanism that prevents programs from automatically closing when there is a shortage of RAM or when manually cleaning the background through a pin in the multitasking menu. Unlike conventional folding, the fixed application remains active in the background, even if you have not used it in a long time.

Main use cases:

• 📱 Social networks and instant messengers: not to miss notifications in Telegram, WhatsApp or VK purification RAM.
• 🎵 Music players: continue playing tracks in Spotify or Yandex Music without rebooting.
• 📊 Navigators and maps: Google Maps or Yandex.Navigator will not be reset during the trip.
• 🎮 Online Games: Preventing Disqualification from Sudden Closing PUBG Mobile or Free Fire.

It's important to understand that anchoring doesn't make an application invulnerable to all types of closure, for example, if you manually swipe it up in the multitasking menu or reboot your phone, the program will shut down, and the feature doesn't protect against forced shutdown through Android settings.

Differences between “application protection” and “background blocking”

Many users confuse fixing with other functions MIUI, And that's what's going on in the background, and we're going to look at the key differences:

Critical nuance: on devices with HyperOS (starting from 2026), the function of "blocking in the background" was renamed "background optimization", and the logic of its work has changed - now the system itself decides which applications can be closed in case of shortage RAM. This means that even a fixed application can be suspended if HyperOS considers it to be “resource-intensive".

⚠️ Note: On some models POCO (for example, POCO F5) The default fixing function is disabled in global firmware. To activate it, you need to switch to India in settings (Settings) → Additionally. → Region).

How to fix the application on Xiaomi: step-by-step instructions

The fixing process differs depending on the firmware version and device model. Consider the universal algorithm that works on most smartphones:

1. Open the app you want to pin (like Instagram or Google Chrome).
2. Press the multitasking button (usually a bottom-up latency swipe or a "square" button).
3. Find the card of the desired application in the list of open programs.
4. Touch the pin pin badge"** (📌) In some models (Redmi Note 12, Xiaomi 13) the icon may be at the bottom.
5. Confirm the action if a pop-up window appears.

After that, the app will remain in the multitasking menu even after cleaning. RAM You can use the "cross" or "basket" button to unplug it, do the reverse: swipe the card up and confirm the unlock.

Notifications from the app arrive without delay-->

On HyperOS devices (e.g. Xiaomi 14 or Redmi) K70) interface has changed a little bit:

1. Open the multitasking menu.
2. Hold your finger on the app card. 1-2 seconds.
3. In the menu that appears, select Secure.

⚠️ Note: On some custom firmware (e.g. Xiaomi.EU), the fixing function may conflict with the Greenify or Brevent optimization modules. If the application still closes, check the settings of these modules.

Hidden settings and advanced capabilities

In addition to the standard fixation through the multitasking menu, the MIUI And HyperOS has hidden features that allow you to more flexibly manage the operation of applications in the background:

1. Priority of processes through ADB

For experienced users, there is a way to force an application to prioritize the system through commands. ADB. This ensures that the program will not be shut down even in critical shortages. RAM. Instructions:

1. Connect your phone to your PC and activate Debugging over USB (Settings → About Phone → MIUI Version → 7 times press to unlock the developer mode).
2. Open the command line and type: adb shell am set-standby-bucket Packet Apps active Where the Application Packet is the program identifier (e.g. com.whatsapp for WhatsApp).
3. To cancel, use: adb shell am set-standby-bucket Package applications working_set

2.Configure via Mi Lab App Monitor (only for the MIUI)

The hidden Mi Lab App Monitor menu allows you to manually adjust the settings of the application in the background.

1. Enter the phone app code ##4636##.
2. Select Battery Information → Mi Lab App Monitor.
3. Find the application and set the Background restriction to No restriction.

This method doesn’t work on all devices and may reset after a firmware update.

3. Use of third-party utilities

If standard Xiaomi tools are not satisfied, you can use third-party applications:

• 🛠️ Greenify – allows you to “freeze” applications, saving battery, but at the same time allows you to work in the background for selected programs.
• 🔄 Brevent – Blocks Optimization RAM Application-specific (root rights required).
• 🔒 Shizuku + AppOps – gives access to hidden Android settings without root.

adb shell settings put global miui_optimization 0

This can improve the stability of background processes, but increases battery consumption.-->

Problems and errors in attaching applications

Despite the apparent simplicity, users often have difficulty using the fixing function, and consider the typical problems and ways to solve them:

1. The pin icon is missing from the multitasking menu

Possible causes and solutions:

• 📱 Outdated firmware: Update MIUI Up to the latest version through Settings → Updating the system.
• 🌍 Regional restrictions: Switch the region to India (see instructions above).
• 🔧 Disabled function: Check the developer settings (Settings) → Additionally. → For developers → Enable attachment of annexes).

2. The attached application is still closed.

This is most often due to:

• 🔋 Aggressive battery optimization: Add the app to exceptions (Settings) → Battery → Optimizing the battery → All applications → Choose the right one. → No restrictions).
• 🧹 Cleaning up. RAM Disable killer tasks like Clean Master or DU Speed Booster.
• 🔄 Reboot device: Fixing resets after reboot - you will have to repeat the procedure.

3. Notifications from the fixed application do not work

The problem is usually related to notification settings:

1. Go to Settings → Notifications → Notifications Management.
2. Find the problem app and turn on all the switches (especially Show notifications and Priority notifications).
3. Check if the app is added to Sleep Mode (Settings) → Battery → Sleeping mode).

💡

If none of the methods help, try resetting the app settings (Settings). → Annexes → Select a program → Warehouse → Clear the data.This often solves background problems, but will delete all the program's internal data (e.g., Telegram cache or Spotify settings).

Comparison of the function on MIUI hyperos

With the release of HyperOS at the end of 2023, the logic of application management has undergone significant changes in the background, and the table below shows the key differences between old and new firmware:

HyperOS's main innovation is dynamic resource allocation, which analyzes which apps you use more often and automatically prioritizes them in your system. RAM. This means that even a loose app (like YouTube) can stay in the background longer if you use it regularly, and HyperOS is more aggressive in closing down underused programs even when they are fixed.

On devices with HyperOS also appeared the function Smart RAM Expansion (in Settings) → Memory that emulates additional gigabytes of RAM with internal storage can help (more apps will stay in the background) and harm (increased wear of flash memory).

How to optimize the work of fixed applications

App consolidation is only part of a multitasking management strategy, and to achieve maximum stability, follow these guidelines:

1.Setting battery priorities

For mission-critical applications (such as messengers or navigators), set the No Limits mode:

1. Go to Settings → Battery → Battery Optimization.
2. Select All Apps and find the right one.
3. Click on it and select No Limits.

2. Cleaning up cache and garbage

The more RAM you have, the more stable the attached applications are.

• 🧹 Cleaning the cache through Settings → Warehouse → Cleanup.
• 🗑️ Remove unused apps (especially Chinese junk like Mi Video or Mi Music).
• 🔄 Reboot the phone 1 time 2-3 This is a day (it resets fragmented memory).

3. Use of Lite versions of applications

If you want to multitask, but the device is weak (e.g. Redmi) 9A or POCO C31), Install lightweight versions of popular programs:

• 📘 Facebook Lite instead of Facebook.
• 💬 Messenger Lite instead of the standard messenger.
• 🎵 Spotify Lite or Yandex Music Go.

They borrow less. RAM and are less likely to be closed by the system.

4. Monitoring of resource consumption

To understand which applications are “eating” memory, use the built-in monitor:

1. Go to Settings. → The phone. → Status of the system → Memory.
2. See which programs are the most important RAM.
3. If an app (like TikTok or Wildberries) consumes a disproportionate amount, lock it in or limit background activity.

💡

On devices with 4-6 GB RAM It is optimal to fix no more than 3-4 applications at a time. On flagships (8-12 GB), this limit can be increased to 6-8, but watch for heating and battery discharge.
