How to Secure an App in Recent Xiaomi: A Complete Guide

Owners of Xiaomi, Redmi and POCO smartphones often face situations where the desired application spontaneously closes in the background. This is especially annoying if you wait for an important message or start the download process. MIUI system and the new HyperOS are known for their aggressive battery optimization, which ruthlessly “kills” processes that are not in active use.

Fortunately, there is a proven way to keep important programs from closing. Assigning an application to the Recents menu is one of the most effective ways to let the system know that the software should stay running. In this article, we will discuss the mechanics of this process in detail, as well as the associated settings that ensure the stable operation of your favorite services.

It’s worth noting that the interface may vary slightly depending on the firmware version and device model. However, the basic principle of the task manager remains the same throughout the Xiaomi ecosystem. Understanding how to interact with the running application window will help you better control your gadget and save battery power, preventing constant restarts of heavy programs.

Why you need to fix applications in memory

Modern smartphones have a huge amount of RAM, but the algorithms of Android and the shells on top of it are designed to save resources at all costs. When you fold a program, it does not stop instantly, but goes into a standby state. However, if the system needs memory to run a new heavy game or camera, it will forcefully complete the processes that it considers the least important.

Assigning an application to the recent task menu serves as a “priority list,” as if you were telling the operating system, “This program cannot be touched even if memory is running out.” This is critical for messengers, navigators, fitness activity trackers or smart home applications that need to run continuously.

⚠️ Warning: Don't attach too many applications at once. If a dozen heavy programs are on the priority list, this can lead to a noticeable decrease in interface performance and accelerated battery discharge, as the system will no longer effectively freeze them.

In addition, fixing helps to avoid a situation where you accidentally swipe an unnecessary card and closes an important process with it. A visual indicator in the form of a lock gives you confidence that the background activity of the program will not be interrupted by your careless touch of the screen.

Instructions: How to pin the application in the menu of recent tasks

The procedure for fixing an application in RAM is performed through a standard task manager. This method works on most devices running MIUI 12, 13, 14 and the current HyperOS. First, you need to open the desired application so that it appears in the list of running processes, and then roll it up to the main screen.

Then, call the running app management menu. On touch-based smartphones, swipe from the bottom up and hold your finger in the center of the screen. If you have three buttons on, press the square button in the bottom navigation menu, and you'll see a list of cards for all active programs.

In the list that opens, find the card of the app you need. Note that some versions of the card shell may show the card shell as a horizontal tape or a vertical list. Make a long press (long-tap) directly on the preview of the application. Do not swipe, namely, press and hold your finger for about a second.

After a long press, a context menu with several options will pop up, you're interested in a lock item, and in different versions of MIUI, it can be called "Secure" or simply designated by an icon. Click on this icon, and now next to the name or the preview of the application, there will be a small lock symbol, which means successful fixation.

Battery settings: Second level of protection

Just fixing the recent tasks on the menu is sometimes not enough, especially on newer models with Snapdragon 8 Gen 2 processors and later, where energy saving is set up as aggressively as possible. The system can find that even the attached application consumes too much resources, and limit its background activity. To avoid this, you need to adjust the battery resolutions manually.

Go to Settings for your smartphone. Go to Apps and select All Apps. In the list that opens, find the app you just installed. You need to go to the detailed settings menu for this particular program. Here we're interested in the Battery Savings subsection.

The default is often "Saving Charge" or "Smart Limits" mode, and you have to change that setting to "No Limits," which removes all backdoor restrictions, allowing the app to use the network and processor even when the screen is off.

Also worth checking for AutoRun permission. In the same app settings menu, find AutoRun and activate the switch, which will allow the program to run itself after restarting the phone, which is useful for alarm clocks and health trackers.

Locking the screen and preventing accidental closures

Another useful feature that is often confused with memory fixing is locking the card from swiping. In some use cases, the user needs to ensure that the application cannot be swiped even accidentally until it manually unblocks, such as when watching a video or using a timer.

The mechanics are similar to the fixing, but the result is different. When you call the recent task menu and you click on the app for a long time, the menu that appears may have a Lock option. Unlike Pin, which affects memory priority, locking the card prevents it from disappearing from the list when you clear all tasks with the Crustic button.

It's important to distinguish between fixing (memory priority) and locking (swiping protection). In modern versions of HyperOS, these features are often combined or work in parallel. If you see a lock after a long press, most likely both mechanisms activate simultaneously.

💡

Tip: If you use Do Not Disturb or On the Plane mode frequently, check your settings after you exit them. Sometimes the system may reset network permissions for background applications, thinking that the connection was forcibly interrupted by the user.

Problem Solving: If the app still crashes

You can do everything you can, you can lock it, you can remove the battery restrictions, and the app will shut down, and then you can have a deeper system setting or version conflict, and the first thing you need to do is check if the device's "Energy Savings" mode is on (the battery icon in the notification curtain), and in this mode, all background processes are severely limited.

Also worth paying attention to is the device memory: If the internal storage space is less than 1GB, the system starts to work unstable and can close applications regardless of settings. Clearing the cache through the standard Security app can help free up resources.

⚠️ Note: Install applications from unknown sources (APK-Site files often cause background services to malfunction, and these programs may not have the right certificates, and Xiaomi’s security system will force them to terminate, ignoring your anchoring settings.

If nothing works, try reinstalling the problem app. Sometimes, during the upgrade process, configuration files accumulate errors that prevent the background services from running correctly. Once reinstalled, re-enact the fixing procedure.

Features of work in HyperOS

With the release of the HyperOS shell, Xiaomi began to introduce new microkernel-based memory management algorithms, visually the menu of recent tasks became smoother and animations more complex, the principle of attaching applications remained the same (long press), but new visual indicators were added.

HyperOS has more detailed statistics on energy consumption, so you can see in the battery settings how many times a particular application has been restricted by the system in the last 24 hours, so you can accurately diagnose whether your fixing is working effectively, and if you see frequent restrictions, you should recheck the "No Limits" settings.

The new shell also improves widgets on the lock screen and in the menu of recent tasks, so that fastened apps can now display more relevant information directly to the card preview without requiring full deployment, making fixing even more useful for quick access to information.

💡

The app’s fixation in the recent task menu, combined with the “No Limits” mode in the battery settings, is the gold standard for ensuring that important programs on Xiaomi smartphones work consistently.
