Apps on Xiaomi: A Complete 2026 Guide

What is the attachment of applications and why it is necessary

If you've ever noticed that your favorite app suddenly shuts down on its own or reboots after switching to another process, you're not alone. App attachment on Xiaomi smartphones is a feature that solves this problem radically. It essentially allows you to nail selected programs to RAM, preventing the system from killing them to free up resources.

But why does it matter? Today's Android devices, including Redmi, POCO and Mi, are using memory management to automatically close the background apps to save battery and improve performance. However, for instant messengers like Telegram or WhatsApp, navigators (Yandex.Maps, Google Maps), music services (Spotify, VK Music), or even games, this can be critical. Imagine listening to a podcast and switching to a browser — and the player suddenly stops. Or you write a message to Viber, and the app reboots when you return to it.

It’s important to understand that the feature doesn’t work on all models the same. For example, on flagships like Xiaomi 14 Ultra or POCO F6 Pro with 12-16 GB of RAM, the effect will be less noticeable than on the budget Redmi Note 12 with 4-6 GB of memory.

How the MIUI fixation mechanism works

Technically, the applications in MIUI (Xiaomi firmware is implemented through prioritizing processes in the Android kernel. When you add a program to the list of fixed, the system assigns it the highest priority (FOREGROUND_SERVICE or PERSISTENT), What's keeping the memory manager from killing it even when you don't have enough resources, is like "close protection" in some custom firmware, but with more flexible settings.

Fun fact: on devices with MIUI 14 and newer, the algorithm is smarter. Now the system analyzes usage patterns and can automatically prioritize frequently used applications even if they are not manually fixed. But manual anchoring still gives you a guaranteed result. For example, if you use Google Maps daily for navigation, but the system for some reason does not recognize it as "important", the anchoring will save you from crashes during the trip.

There is a downside: attaching too many applications (more than 5-7) can lead to slowing down the interface, especially on devices with 4-8 GB of RAM. The fact is that the system reserves memory for fixed processes, reducing resources for other tasks, so it is important to choose only really critical programs.

Step-by-step: how to fix the application on Xiaomi

The fixing process differs depending on the version of MIUI, but the general logic holds. Consider the universal method that works on most devices, including the Redmi Note 13 Pro+, POCO X6 and Xiaomi 13T:

1. Open Settings → Applications → Application Management.
2. In the upper right corner, press three dots (⋮) and select Special Permits.
3. Scroll down and find App Lock (in some versions – Cleanup Block or Closing Protection).
4. Activate the slider in the top corner, then select apps from the list or click Add Apps for manual selection.
5. Confirm the changes. Now the selected programs will not close when the memory is cleared.

On MIUI 12 and older, the path may be slightly different:

Settings → Battery and Performance → Battery Management → Applications selection → Fixing

If you have a POCO Launcher or other shell, look for similar items under the "Applications" or "Battery" section.

Check the version of MIUI (Settings → About the phone)

Close unnecessary background processes (via Task Manager)

Choose no more than 5 critical applications

Reboot the phone after settings (optional)-->

Once secured, it is recommended to restart the app so that the changes take effect, for example, if you have fixed YouTube Music, close it through Task Manager and reopen it, so that the system correctly applies the new rules of memory management.

Which apps should be fixed and which ones should not

Not all programs need to be fixed.-5 candidates who really need it:

• 📍 Navigators: Google Maps, Yandex.Maps, 2GIS – so as not to stray from the route when switching to music or messenger.
• 💬 Messengers: WhatsApp, Telegram, Viber – for instant notifications and saving chats in memory.
• 🎵 Music Services: Spotify, Apple Music, VK Music – So that tracks do not interrupt when multitasking.
• 📊 Fitness trackers: Google Fit, Mi Fitness, Strava – for continuous monitoring of activity.
• 🎮 Online gaming: PUBG Mobile, Call of Duty Mobile – to avoid discounts when switching to Discord.

Here's what you don't want to fix:

• 📱 Social networks (Instagram, TikTok, Facebook) – they already consume a lot of memory and are often updated in the background.
• 📥 File Manager (Mi File Manager, ES Conductor – They don’t need a permanent job.
• 🔄 Service utilities (Memory Cleaner, Antivirus) - they manage resources themselves.
• 📅 Calendars and notes – synchronization occurs periodically, without the need for constant activity.

💡

If you have secured an application but it is still closing, check the battery settings for it. In some versions of MIUI, you need to further disable Battery Optimization in the Battery Management section.

Common Problems and Their Solutions

Even after the application is fixed, it can be incorrect, and let's look at the typical scenarios and how to fix them:

The problem with MIUI 13 and later, where fixing can conflict with Deep Optimization, is particularly noteworthy. If you notice that fixed applications are still killed, try:

1. Disable Deep Optimization in Settings → Battery → Battery settings.
2. Add the application to the Cleaning Exceptions (if there is such a clause).
3. Check if Google Play Services is blocking background activity (in the app settings).

Alternative ways to protect applications from closure

If standard fixing is not suitable (for example, on devices with HyperOS or custom firmware), alternative methods can be used:

• 🔧 Developer Settings: Enable Do Not Kill Processes (Settings) → The phone. → Version. MIUI — tap 7 times to unlock, then find the option in Additional settings → For developers).
• 🛠️ ADB-Commands: You can manually prioritize the application with the help of a PC: adb shell am set-standby-bucket [package_name] Active This will force the program to be classified as "active".
• 📱 Third-party utilities: apps like Greenify (in Boost mode) or Battery Optimizer allow you to flexibly adjust background activity.
• ⚡ Shutdown MIUI Optimization: You can completely deactivate Xiaomi optimization on rooted devices, but it’s risky for stability.

For users of HyperOS (the new firmware Xiaomi debuted on Xiaomi 14 in 2026), the process has changed a little. Now the fixing is integrated into Settings → Apps → Permissions → Special Access → App fastening. In addition, the option “Priority Notifications” has appeared, which indirectly affects background activity.

💡

On HyperOS devices, fixing works more efficiently thanks to an improved memory management algorithm, but requires a mandatory reboot after changing settings.

Effects of fastening on battery and performance

Many users fear that attaching apps will increase battery consumption, which is partly true: background processes do consume energy, but the effect depends on the type of program:

• 📉 Minimum impact: messengers (Telegram, WhatsApp) in the waiting mode of notifications.
• 📈 Average impact: Music services (Spotify, YouTube Music) when playing.
• ⚠️ High impact: navigation (Google Maps) with constant GPS and games with online synchronization.

To minimize the negative effect:

1. Use Power Saving Mode for non-critical applications (in battery settings).
2. Limit background activity for social media through Settings → Apps → Permissions → Background activity.
3. Check your battery consumption statistics regularly in Settings → Battery → Battery Use.

An interesting test: on the Xiaomi 13 Pro with Google Maps and Spotify fixed, battery consumption increased by only 3-5% in 8 hours of active use compared to the non-fixed versions. However, on the Redmi 10A with 4 GB of RAM, the difference was up to 12% – here it is important to balance between convenience and autonomy.

💡

If you notice a lot of heat on your phone after you have attached several apps, check them through Settings → Memory → Memory Use. Perhaps one of them leaks and consumes too much resources.

💡

App attachment is a powerful tool for multitasking control, but requires a measured approach: Start with 1-2 critical programs and monitor the performance of the device.
