Modern smartphones, such as Xiaomi Redmi, are powerful computing devices capable of performing many tasks simultaneously. However, it is this multitasking that often causes rapid battery drain and reduced system performance. Users often notice that even when at rest, the phone gets warm or loses charge, and this may be due to incorrect operation of apps in a hidden state.
The concept background mode on Android refers to the ability of an application to continue executing certain processes even when you minimized it or turned off the screen. This is necessary to receive notifications from instant messengers, update music or download files, but uncontrolled activity harms the device. In the shell MIUI or HyperOS there are specific tools for fine-tuning this behavior.
In this article we will analyze in detail the mechanics of hidden processes, ways to limit them and methods for forcibly stopping unnecessary services. You will learn to distinguish systemically important tasks from parasitic ones and understand how to configure your phone so that it works for a long time and stably. A deep understanding of these processes will help you extend the life of your gadget's battery.
What is background running of applications in the Android system
Background mode is a state in which the application interface is not displayed on the screen, but its processes continue to consume processor and RAM resources. The operating system Android is designed to instantly switch between tasks, maintaining their state in memory. This ensures smooth operation, but requires constant power supply.
When you minimize a browser or social network, it does not always go to sleep. Many services use background services to synchronize data, download content, or track geolocation. On devices Xiaomi with their aggressive memory optimization, such processes can be terminated by the system automatically unless special permissions are set.
There is a fine line between useful background activity and malicious. For example, the navigator needs to know your location even when the screen is off, and the messenger needs to receive messages. At the same time, games or calculators should not run in the background. The user must independently determine the priorities for each installed software.
The system resource monitor shows which apps consume energy in standby mode. It often turns out that the lion's share of the charge is taken not by those applications that you actively use, but by those that quietly mine cryptocurrency, show ads or collect analytics in the background.
⚠️ Attention: Completely stopping all background processes may result in you stopping receiving calls, WhatsApp messages and notifications from banking applications. The settings should be carried out selectively.
How to check application activity in Xiaomi settings
To start managing, you need to get a complete picture of what is happening inside the system. The shell MIUI provides advanced statistics that are hidden from the eyes of the average user in the standard menu. Primary diagnostics begins with the battery section.
Go to Settings → Battery → Battery consumption. Here is a list of all apps, sorted by energy consumption over the last day or week. Pay attention to the apps that are at the top of the list but that you have hardly used. This is a clear sign of active background work.
More detailed information can be obtained through the “Applications” menu. Click on a specific app, select Battery consumption and look at the ratio of time spent in the foreground and in the background. If background time significantly exceeds active usage, this is a cause for concern.
It is also worth checking the "Memory" section in the developer settings, if it is activated. It displays a list of running services in real time. This allows you to see the “live” processes that are currently loading the processor, even if the phone’s screen is turned off.
Activate the developer menu by clicking on the build number 7 times in a row in the “About phone” section. This will give access to extended statistics of running services.
Managing permissions and autorun in MIUI
One of the main features of smartphones Xiaomi Redmi is the presence of a built-in autorun manager. Unlike pure Android, here you can strictly limit the list of apps that have the right to start when the phone is turned on. This is the first line of defense against excess garbage in memory.
Go to the application Security → Permissions → Autorun. You will see a complete list of installed apps with switches next to each. It is recommended to disable autorun for all applications except instant messengers, alarm clocks and antiviruses. Browsers, games and stores do not need to work immediately after turning on the device.
The second important mechanism is permissions to run in the background. In the same “Security” menu, find the item Permissions and select the “Work in the background” category. Here, the system offers three behavior options for each application: "Restrict", "No restrictions" and "Smart selection".
Selecting the "Restrict" mode will cause the system to kill the application process soon after you terminate it. It's ideal for games and utilities. The “No restrictions” mode should be set only for critical services, such as Telegram or an email client, so as not to miss important notifications.
| Application type | Recommended mode | Consequences of choice |
|---|---|---|
| Messengers (WhatsApp, Viber) | No restrictions | Instant receipt of messages and calls |
| Games and entertainment content | Limit | Battery saving, the process is killed when minimize |
| Banking applications | Smart selection / Limit | Security, notifications may arrive with a delay |
| Navigators and taxis | No restrictions | Correct operation of the route when the screen is off |
Remember that the settings may vary depending on the firmware version. The interface HyperOS may have a slightly different menu structure compared to the classic MIUI 12 or 13. Always check the relevance of the menu items on your specific device.
Setting energy saving for individual applications
Global energy saving settings affect the entire device, but sometimes specific settings are required. In the battery menu of each individual application on Xiaomi there is a special switch that controls its behavior in standby mode. This is a powerful tool for combating “gluttonous” apps.
Open the settings of a specific application through the system menu and find the item Activity Control. Here you can choose a strategy: “No restrictions”, “Battery saving” or “Hard restriction”. Selecting the "Battery Saver" mode allows the application to run in the background, but limits the use of the network and GPS.
The "Hard Restriction" mode actually prohibits any background activity. The application will only work when it is open on the screen. Once you minimize it, the system will forcefully stop all associated processes. This is a radical but effective measure for apps that you rarely use.
It is also worth paying attention to the “Battery Optimization” function in the general settings. It automatically analyzes usage patterns and suggests limiting rarely used applications. Trust the system algorithms, but periodically check the list of exceptions so as not to block what you need.
☑️ Optimizing background processes
Forced stop and memory clearing
Sometimes software glitches lead to the application “hanging” in the background and continuing to consume resources even after trying to close it. In such cases, standard minimizing does not help, and a forced stop of the service is required through system settings.
To perform this operation, go to Settings → Applications → All applications. Find the problematic app in the list, click on it and select the button Stop. The system will warn you that the application may not work correctly until the next launch - this is normal and safe.
To quickly clear RAM, you can use the built-in utility in the Security application. Clicking the Cleanup button kills background processes that are not whitelisted. However, it is worth remembering that constant manual memory clearing on modern versions of Android is often useless, since the system itself effectively manages resources.
A more effective method is to reboot the device. Restarting the phone Xiaomi Redmi completely clears the process cache and resets all frozen services. It is recommended to do this at least once a week to maintain the stability of the operating system.
⚠️ Attention: Forcibly stopping system applications (such as “Phone”, “Contacts” or “System Interface”) can lead to unstable operation of the phone until a reboot. Proceed with caution.
What is the “com.android.systemui” process?
This is the system interface responsible for displaying the status bar, notification panel and navigation buttons. It cannot be stopped, as this will lead to the disappearance of the phone management interface.
Advanced settings through the developer menu
For advanced users who want to gain maximum control over background processes, there is a developer menu. Hidden here are settings that allow you to limit the number of simultaneously running applications or completely prohibit background activity for the entire system.
To find these settings, activate developer mode and go to the appropriate section. Find the item Background process limit. By default, there is “Standard limit”, but you can select the “No background processes” option or limit the number of processes to a specific number, for example, two.
Another useful option is “Do not save actions”. When this feature is enabled, the system will destroy application activity as soon as the user leaves it. This creates a “cold start” effect every time you open the app, which saves memory, but can slow down operation.
Using commands through ADB (Android Debug Bridge) allows you to manage services even more finely. Using the console, you can send commands to stop specific packages or change their priorities. This requires a connection to a computer and some basic knowledge of the command line.
adb shell am set-inactive app.package.name trueThis command puts the application into an inactive state, preventing it from running background tasks until the user explicitly opens it again. This is a powerful tool for combating annoying software that cannot be removed using standard methods.
The developer menu gives maximum control, but changing the settings inexperienced can make the phone unsuitable for everyday use. Return the default settings after experiments.
The impact of background processes on the battery and performance
The accumulated effect of many applications running in the background inevitably affects the autonomy of the device. Even if each individual application consumes a little power, their combined impact can reduce screen time by 20-30% per day.
In addition, background processes take up RAM. When free memory becomes low, the system begins to actively use the page file or constantly reload applications, which leads to micro-lags and slowdown of the interface. This is especially noticeable on budget models Redmi with a small amount of RAM.
Constant activity in the background also leads to heating of the case. The processor is forced to process data even while the phone is in your pocket. Prolonged overheating negatively affects the physical condition of the battery, accelerating its degradation and loss of capacity.
Regular audit of background activity is not a one-time procedure, but part of the hygiene of using a smartphone. When installing new applications, immediately check their permissions and set up autorun. Prevention is always more effective than dealing with consequences.
⚠️ Attention: Battery characteristics and energy saving algorithms change with each new generation of phones. What worked on Redmi Note 8 may work differently on Redmi Note 13.
Use the Battery widget on the desktop for quick access to consumption statistics. This will help to instantly identify a parasitic application that has begun to actively work in the background.
Why do applications run in the background, even if I closed them?
Modern operating systems use a notification and synchronization mechanism. Closing completely often just means minimizing the interface while services remain active to perform their tasks.
Is it safe to disable autostart for all applications?
Yes, it is safe. You can always launch the application manually. Disabling autorun only prevents them from starting on their own when you turn on the phone, saving resources.
How to find out which application is slowing down the phone in the background?
Go to Settings → About phone → All characteristics → Tap 7 times on “Kernel version” (to enable developer mode). Then, in the developer menu, select “Running services.”
Can the background mode affect the mobile data?
Yes, many applications update content through the mobile network in the background, using up your traffic. Limit background data transfer in the settings of SIM cards and mobile network.
What is the “sleep mode” of applications on Xiaomi?
This is a function that automatically puts rarely used applications into a deep sleep state, prohibiting them from any activity in the background until the next manual launch by the user.
