Xiaomi, Redmi and Poco smartphone owners often face aggressive system optimization that forcibly shuts down unused programs, causing notifications from messengers to arrive with a delay, music to be interrupted when it folds, and the navigator stops plotting its route. The problem lies in the deep integration of energy-saving mechanisms that by default consider any background processes to be an unnecessary load on the battery.
But MIUI and the new HyperOS provide users with advanced tools for manual process control. Competent configuration allows you to keep important services active without compromising the autonomy of the device. You don't have to be a programmer to understand these settings, just consistently perform several actions in the menu of the smartphone.
In this article, we will take a look at all the available ways to fix applications, explain the difference between autostart and no restrictions, and also consider the hidden functions of the developer. Understanding the logic of the system will help you forget about missed calls to Viber or Telegram forever.
Mechanism of background processes in Xiaomi shells
The Android system on the Chinese manufacturer's devices is undergoing major modifications, with engineers imposing strict limits on the number of processes running simultaneously to ensure the claimed battery life. When you fold an application, it not only goes into a standby state, but after a certain period of time is forcibly unloaded from RAM.
The main control tool is the task manager, which analyzes the energy consumption of each service that is running. If the program does not have special permissions, the system classifies it as a “resource devourer” and ends its work, this is especially true for models with RAM up to 6 GB, where cleaning occurs almost instantly after switching to another window.
It is important to distinguish between autostart and no-limits: the first allows the program to run itself after the phone is restarted, and the second prevents the system from killing the process while working. Both messengers and activity trackers need to be configured correctly to work consistently.
Users often confuse the usual folding with the actual background. Visually, an application may remain on the list of recent tasks, but in fact, its process has already been destroyed by the system, which is why setting priorities is a critical procedure immediately after buying a new device.
Auto Start Configurement and No Limitations
The first step is to manually allow autoruns for the required programs, which is disabled by default in new firmware for all third-party applications for safety and cost savings, and you need to tell the system which services can be run with the operating system.
To access the control menu, go to Settings, then select the App and find the AutoRun tab. The list that opens will show all installed programs, find the desired application (such as WhatsApp or Yandex.Navigator) and activate the switch opposite it.
However, turning on the autostart is only half the battle. Even with a valid launch, the system can shut down the application after a while. To prevent this, you need to set up a power profile. Go to Settings → Applications → All applications, select the desired program and click on Saving battery.
In the menu that opens, select No Limits, which gives the application the highest priority and prevents the system from forcibly ending its processes. The standard No Limits mode (which is often the default) still allows the system to kill the process when memory is scarce, whereas the option we choose ignores most system limits.
☑️ Checklist of basic application settings
It is worth noting that once the operating system is updated, the settings may reset to factory values, in which case the procedure will have to be repeated again for all mission-critical services, and regular checks of these parameters help to maintain the stability of the smartphone in the long run.
Blocking the application in the multitasking menu
One of the easiest and most effective ways to keep an application in RAM is to use the lock function in Task Manager, which is especially useful for programs you're using right now that you don't want to close when you clear the memory with the "Close All" button.
Open the menu of running applications by swiping from the bottom up and holding your finger (or pressing the navigation button), find the card of the desired application and pull it down (in some versions of MIUI you need to click on the lock at the top of the card or hold your finger on the card until the lock icon appears).
The applications that are blocked in this way ignore the command to clean the memory mass, and they will stay in the background until you manually close them or restart the device, which is ideal for navigators, recorders or tracking physical activity during exercise.
⚠️ Attention: Task Manager locking doesn't give absolute warranty. If the system critically lacks free RAM to run a heavy game or camera, it can ignore the lock and unload even a secure application.
Using a lock doesn't affect battery consumption as aggressively as eliminating optimization altogether, but it creates an additional security buffer. Combine this method with energy saving settings to achieve maximum effect.
Advanced Battery Saver Settings and Optimizations
In the deepest settings, you have the Advanced Settings or Special Rights menu, which sometimes requires multiple taps, and you have the controls that can change the behavior of the operating system, and you have to focus on the MIUI optimization section.
Some firmware versions have a hidden menu called through dialing or a clause in the developer settings. However, the standard path is through the security menu. Open the Safety app (green lightning icon), go to the Battery section and check active profiles. The No Limits mode in the global battery settings disables all background restrictions, but this is a last resort.
A more subtle setting is available through the developer menu. To activate it, go to Settings → About Phone and quickly click 7-10 times on the line MIUI Version (or OS Version). Once the notification "You became a developer" appears, go back to the main settings menu, open Additional → For developers.
Find a section related to background processes. There may be an option called "Background Process Limit." Make sure it has a "No Limit" or "Standard Limit" value. Set a hard limit (e.g., "No More than 2 Processes") will result in constant restarts of your services.
Hidden command to reset battery settings
It is also worth checking the notification settings for a particular application. Sometimes the problem is not closing the process, but blocking push notifications. In the application management menu, make sure that all types of notifications are enabled, including Important and Other.
Comparison of operating modes and their impact on the system
Understanding the differences between the available application modes will help you choose the best strategy for each case. Not all programs require maximum resources, and for some of them, aggressive optimization is even useful.
Below is a table showing the impact of different settings on system behavior:
| Type of setup | Impact on the battery | Probability of closing | What applications are suitable for |
|---|---|---|---|
| Limited (by default) | Minimum | Tall. | Rarely used utilities |
| No Limits (Battery) | Average. | Low. | Messengers, mail. |
| Lockdown in dispatcher | Depends on the app. | Medium (with a lack of RAM) | Navigators, music |
| Auto Start + No Limitations | High. | Minimum | Trekking, smart home, calls |
As you can see from the table, there is no universal solution. Messengers are critical to push notifications, so they need a "No Limits" mode. Music players are more important than memory retention (locking), and for the navigator - working with the screen off.
Excessive number of applications with “No restrictions” can lead to a noticeable reduction in the smartphone’s life from a single charge, the system stops “sleeping” the background processes, and they continue to consume the CPU and network resources.
💡
The optimal strategy is to give full rights only to those applications that must work constantly (messengers, callers), and for the rest to use selective lock in the Manager.
Additional recommendations and elimination of problems
If even after all the settings, the application continues to close, the problem may lie in the program itself. Some applications do not correctly implement background services and cannot properly restore their state after suspension, in which case cleaning the cache or reinstalling the application helps.
It is also worth considering that third-party memory cleaners and antiviruses can conflict with MIUI system settings. If you use such utilities (for example, Clean Master or DU Battery Saver), try to remove them.
Newer versions of HyperOS have added an extra layer of memory protection that can ignore user settings when the device gets hotter, and if the phone overheats, the system forcibly closes all background tasks regardless of settings to lower the processor temperature.
⚠️ Warning: Do not install multiple memory management applications at the same time. They will constantly compete for the right to close each other's process, which will lead to rapid battery drain and unstable interface operation.
Watch out for shell updates. Xiaomi engineers regularly release patches that fix memory management errors. If the problem appears after the update, it makes sense to wait for the next patch or temporarily use older, stable versions of apps.
💡
Try to turn off adaptive brightness and always active screen (AOD) while testing background work. These features often wake up the processor, which can provoke the system to clean up memory more aggressively to compensate for the increased power consumption.
