Xiaomi’s smartphones are famous for their performance, but even the powerful hardware eventually begins to experience difficulties with multitasking. Users often notice that the phone begins to heat up and the battery melts before their eyes, even though the device is idle.
With MIUI and the new HyperOS, memory management mechanisms are aggressive, but some applications have learned to bypass these limitations: They can restart their services, send data to a server, or simply hang in RAM, slowing down the interface. Understanding how to manage these processes properly is key to extending the life of your gadget’s battery.
In this article, we will take a look at all the ways you can stop unnecessary activity, how to use built-in system tools, hidden developer settings and third-party utilities to take full control of your device, and how to set up background processes correctly can increase battery life by up to 30%.
Why apps work in the background and why stop them
Many users mistakenly believe that the folded application will stop working completely. In fact, the background mode allows programs to perform important tasks: messengers wait for messages, navigators track location, and email clients check new emails.
For example, a simple calculator or flashlight can request geolocation and Internet access, and still transmit data even when it's off, and it not only consumes traffic, it also loads the processor. In the Android ecosystem, these processes are called services, and there can be dozens of them.
Uncontrolled operation of such services leads to three main problems: fast battery discharge, overheating of the case and a lack of RAM to run heavy games. Regular cleaning of the background helps to keep the system in good shape, especially on models with 4 or 6 GB of RAM.
⚠️ Warning: Complete shutdown of Google system services or services MIUI This can cause notifications to malfunction and interface failures. Only stop third-party applications.
There is a myth that the constant forced shutdown of all programs is useful. It is not so: the system has to re-run the necessary components, which creates an additional burden.
Standard methods of closing applications through the MIUI interface
The easiest and safest way to free up resources is to use the standard menu of recent tasks, which is conveniently implemented in the MIUI shell and allows you to quickly assess what is running at the moment, and to access it you need to swipe from the bottom up (or click the menu button, depending on the type of navigation).
To close all programs at once, just press the "Clean" button (the cross icon), but this method is often ineffective for "stubborn" applications that immediately start again, and a more effective way is to individually manage via swipes.
To do a deeper cleaning, you can use the built-in Security tool, which analyzes memory consumption and suggests that you close the processes that are most stressful to the system, and it's an optimizer that works at the system level, not just closing windows.
Users who are used to classic management should pay attention to the “Close All” button in the menu of running applications. Long clicking on the app icon in this menu can also trigger a context menu with additional information.
Forced stop through system settings
If standard closing fails and the application continues to eat the battery, you need to use the forced stop function, which breaks all connection of the process to the system and completely unloads it from RAM. You can find this option in the settings section.
Go to Settings → Applications → All Apps. In the list that opens, find the problem program and click on it. In the app information menu that opens, you will see the Stop or Forced Stop button.
☑️ Pre-stop checks
Once you press this button, the process is complete, but it's worth remembering that when you start the program next time or reboot the phone, it can activate its services again, and to prevent this, you need to further limit background activity.
In some versions of HyperOS, the stop button may not be active for system applications, which is protection against accidental device failure. There are other restrictions for such programs, which we will discuss below.
Set up background activity restrictions and battery
Modern versions of Android and Xiaomi shells allow you to flexibly adjust the behavior of applications in the background, this is the most effective way to combat discharge without losing functionality, the system will decide when you can “freeze” the program and when to let it work.
In the app-specific information menu (Settings path → Applications → All apps → [Select App]), you need to find Activity Control or Battery Savings, and there are three modes available: No Limitations, Restricted Background and Hard Limitation.
Hard Limit mode completely prevents the application from running in the background, no notifications will come, and data synchronization will stop until the program is manually opened, ideal for games or rarely used utilities.
| Mode of work | Description of behaviour | Impact on notifications | What's the point? |
|---|---|---|---|
| No restrictions. | The app works freely | They come in instant. | Messengers, mail, alarm clocks. |
| Limited background | The system limits background processes | They may be late. | Social media, news feeds |
| Strict limitation | Background work is completely prohibited | They don't come. | Games, heavy editors, rarely used programs |
By choosing a limited background mode, you find a balance between functionality and energy saving, and MIUI will decide when to suspend activity based on your usage patterns.
What is the “freezing” of applications?
Using Developer Mode to Manage Processes
For advanced users who want to gain full control of RAM, there is a “Developers” menu, which is a hidden settings section that gives access to the technical parameters of the Android system.
To activate this mode, go to Settings → About phone and 7 times quickly click on the version of MIUI or HyperOS. After the message “You became a developer” in the settings menu will appear a new section.
Inside the Developer section, we're interested in the "Background Process Limit" section, where you can set a hard limit on the number of applications that can be in memory at the same time, for example, setting a "No More than 2 processes" value, you will force the system to unload everything that is superfluous.
⚠️ Warning: Setting too low a limit of background processes (0 or 1) can lead to constant restarts of system services, interface lags, and unstable Bluetooth and Wi-Fi operation.
There's also a "Do Not Stay Activated" feature on this menu, which, if enabled, will destroy the application's activity as soon as the user switches to another task, a radical measure that is only useful for testing or on very old devices.
💡
Use the “Show Processes” feature in the developer menu to see in real time how much resources each application is using, which will help to identify the hidden “eaters” of the battery.
Automation and third-party cleaning solutions
Xiaomi's built-in tools are good, but sometimes a more flexible approach is required. The standard Security app allows you to set up automatic memory cleanup, so you open the app, go to Memory Cleanup and enable auto-cleaning.
You can also use the Extended Cleanup feature in the same application, which analyzes installed programs and suggests removing cache or stopping processes that have not been used for a long time, which helps keep the system clean without manual intervention.
Third-party launchers and memory management utilities (such as Greenify or SD Maid) can offer finer tweaks, allowing apps to be put to sleep by simulating deleting them until you run them yourself, but on modern versions of Android, their effectiveness is reduced by the system’s strict limitations.
It's important not to overdo it with the installation of many "cliners." Often, these programs consume more resources than they save by constantly working in the background and checking other processes. The built-in functionality of MIUI is usually enough for a comfortable work.
💡
The optimal strategy is to combine automatic memory cleaning in the Security app with manual back-end activity restriction for 3-5 of the heaviest applications.
