Owners of Xiaomi, Redmi and Poco smartphones often face a situation where a running program suddenly closes or “flys” to the desktop, a phenomenon that can occur in heavy-duty games, as well as in simple utilities like instant messengers or a browser, such behavior causes irritation, interrupts workflow and creates a sense of instability of the device, even if it is new.
The reasons for this behavior lie in the complex architecture of the MIUI shell or HyperOS, which aggressively manages resources to save battery life, and can also be influenced by overcache, lack of RAM or conflicts of Android versions with the code of a particular application. Understanding the nature of the failure is the first step to restore normal operation of the gadget without going to the service center.
In this guide, we will take a look at all possible scenarios, from simple software errors to more serious system conflicts, learn how to properly adjust energy saving, clean up system debris and use hidden debugging functions. A competent diagnostic approach will solve 95% of departure problems on your own.
Aggressive energy saving and MIUI optimization
The most common reason Xiaomi phones are dropping apps in the background is because of the built-in optimizer. MIUI is set to maximum autonomy by default, so it ruthlessly kills processes that it believes are consuming too much resources or have simply not been actively used for a long time, often with navigators, step trackers or instant messengers.
To prevent a forced shutdown, you need to manually change the settings for each important application. You need to go to the Settings menu → Apps → All applications, find the desired program and select Battery. Here you should set the "No Limits" mode, which tells the system that this process is a priority and should not be terminated forcibly.
💡
Set No Limits mode for navigators and workout trackers, otherwise they may shut down in the middle of a route or run, losing all data.
Also worth paying attention to is the Memory Extension feature, which is designed to help, but in some cases virtual memory is slower than physical memory, which can lead to timeouts and heavy applications. Try disabling this option in Settings → Expand memory and check the stability of the work.
- 🔋 Switch power saving mode to Performance during games to allocate maximum resources to the processor.
- 🚫 Turn off autostart for unnecessary programs so they don’t conflict with active tasks in the background.
- 📱 Check the pop-up settings for instant messengers so they don’t block the interface of other apps.
Lack of internal and operational memory
Lack of free space is a classic problem that users often ignore until a critical failure occurs: When a smartphone’s internal memory is over 90% full, the system lacks space to create temporary files and swaps, which causes applications to fail to download the necessary data and crash.
A similar situation is observed with RAM: if you simultaneously keep a dozen tabs open in your browser, play a resource-intensive game and listen to music through a streaming service, the limits of RAM will be exhausted, at which point the Android operating system forcibly closes the least priority processes, which is perceived by the user as “flight out”.
To diagnose and clean up, use the built-in Cleanup tool. Click on the desktop broom icon or go to Settings → Storage. The system will prompt you to delete unnecessary files, duplicate photos and app cache. Regularly cleaning at least 3-5 GB of space significantly improves the stability of the interface.
☑️ Memory check
Cache overflow and application data errors
Accumulated temporary files, or cache, are designed to speed up the launch of programs, but over time they can become corrupted or occupy a critical volume. Corrupted cache is a common reason why an application crashes immediately after launch or when it moves to a particular section, especially for social networks and browsers, which store huge amounts of graphical content.
To fix the problem, you don't have to delete the application completely. Just clean the data through the system menu. Go to Settings → Apps → All applications, select the problem program and click "Clean." It is important to distinguish between two types of cleaning: "Cache Clearing" (safe, deletes only temporary files) and "Clean all data" (resets the application to the state immediately after installation, removing logins and settings).
⚠️ Note: Before performing a complete data cleanup, make sure you remember the password from your account in the app, as all local information will be permanently deleted.
If the problem is observed in the Chrome browser or MI Browser, it is also recommended to clear the browsing history and cookies. Sometimes the conflict is caused by old extensions or plugins that are no longer supported by the developer.
Version conflicts and problems after update
Frequently, flights start immediately after an operating system or application update, because new versions of programs may not be fully optimized for a particular version of Android or HyperOS firmware. This is especially common on global firmware versions, where localization and integration of Google services may not work smoothly.
If the app stopped working after the update, the first thing to do is check for new patches in Google Play Market or GetApps. Developers quickly release hotfixes to fix critical bugs. If there are no updates, try removing the app itself (return to the factory version) through the app management menu and check the work.
What is Android System WebView?
In some cases, clearing the cache of Google Play services helps. To do this, go to Settings → Apps → All apps, turn on the display of system processes and find Google Play Services. Clearing the cache here can solve problems with authorization and running dependent applications.
Comparison of failure management methods
The right treatment depends on the symptoms. If an application goes out immediately when it starts, the problem is likely to be the damaged files. If it works for a while and then shuts down, it's the memory deficit or overheating. Below is a table that helps you navigate quickly.
| Symptoms. | Probable cause | Action. |
|---|---|---|
| Launch departure | Damaged cache or files | Cleaning the application data |
| Closing in the background | MIUI Energy Conservation | No-limits regime |
| Relegation in the games | RAM shortage or overheating | Closing of background applications |
| Errors in system applications | Google services failure | Update to Google Play Services |
| Permanent departures of all programs | System firmware failure | Reset to factory settings |
The system approach eliminates most software errors, but if none of these methods work, you should think about more radical measures, such as resetting your settings or flashing your device, but before you do, make sure that the problem is not in the hardware.
💡
90% of problems with outgoing applications are solved by changing energy saving settings or cleaning the cache, without the need for complex repairs.
Hidden Developer Settings and Debugging
For advanced users who aren’t afraid to experiment, there are debugging tools. The Developer Menu (which is activated by clicking seven times on the build number in the About Phone section) can find settings that affect stability, such as limiting background processes can help or harm, depending on the use case.
One of the useful features is Do Not Save Actions. If this option is enabled, the system will destroy the background activity of each application as soon as the user leaves the screen. Make sure this item is turned off. It is also worth checking the animation settings: sometimes accelerating the animation to 0.5x or completely turning it off reduces the load on the GPU.
⚠️ Warning: Changing the settings in the Developer Menu can cause the system to run in an unstable way.
If you encounter a specific error code, you can try to decrypt it through logcat, but this requires a connection to a PC and installing an ADB (Android Debug Bridge). For the average user, it is enough to know that constant departures after installing custom fonts or themes indicate an interface conflict.
When Removal or Repair Is Required
If neither cleaning up memory, reconfiguring power saving, nor reinstalling apps helped, perhaps the problem lies deeper: Damage to system files after a failed update or virus infection (rarely, but possible when installing APKs from unverified sources) require a complete reset. Before settings → About phone → Reset, be sure to back up your data.
In rare cases, departures are a symptom of hardware malfunction, memory cell degradation, CPU overheating due to dried thermopaste or motherboard problems can manifest themselves this way, and if the phone warms even in plain, and departures are accompanied by freezes or reboots, this is an occasion to contact the service center.
To sum up, Xiaomi’s stability largely depends on the correct user interaction with the system: Regular memory monitoring and proper setting of access rights allow you to enjoy the performance of the smartphone without annoying interruptions.
