Modern Xiaomi smartphones running MIUI shells or the new HyperOS have a powerful resource management system that often works automatically. However, for advanced users and those who want to maximize battery life, it is critical to understand what processes are running in the background. Background applications are programs that continue to function even after you turn their window or close the screen.
Uncontrolled growth in these processes can lead to rapid battery drain, heating of the case and slowing down the interface. Android allows applications to run in hidden mode to update the news feed, receive messages or synchronize data, but sometimes this mechanism gets out of control. In this article, we will detail how to find, analyze and, if necessary, limit the activity of background services on your device.
Understanding how Xiaomi manages memory will help you avoid accidentally removing important system processes that are responsible for communication stability or notifications. We will look at both the standard diagnostic tools and hidden engineering menus available on most current models.
Analysis through the About Phone menu and memory status
The fastest and safest way to get the primary information about system workload is to use the built-in memory widget. On most Xiaomi devices with MIUI shell, this tool is available directly from the settings menu or through a swipe in the Security app. By clicking on the number denoting free RAM, you will see a list of recently used applications that the system has not yet unloaded from RAM.
But this method only shows the tip of the iceberg, where you see active tasks, but you don't always see hidden services that consume CPU resources. For a deeper analysis, you need to go to specialized developer tools. It's important to distinguish between applications that you've recently launched and those that start automatically when you boot.
⚠️ Warning: Forced cleaning of all background processes through the Clean button can cause system services to restart, which will temporarily increase battery consumption, as the processor will be loaded with their re-start.
Using a full-time task manager is warranted for quick checks, but finding energy eaters requires more nuanced tools. In the following sections, we will move on to professional monitoring methods that give a complete picture of what is happening inside the operating system of your smartphone.
Use of the “Developers” menu
The most complete list of all running processes, including system services and background applications, is available in the hidden settings section. To activate this mode, go to Settings → About phone and quickly click on the MIUI build number seven times. Once the developer mode activation message appears, a new item will appear in the settings menu.
In the "Developers" section, we're interested in "Running services" -- this is a real picture of RAM usage, not just the names of the applications, but the specific services they use, which reveals, for example, that the messenger consumes little resources, and the associated update service is loading the system.
This menu also shows how long a service lasts and how much RAM it takes. If you see a process that has been running for several days and consumes a significant amount of memory, it's a candidate for forced shutdown or deletion. But beware: stopping system processes can lead to unstable interfaces.
⚠️ Note: The developer menu does not allow you to stop processes marked as system (System, Android, MIUI). Trying to do this can lead to a cyclical reboot of the device.
This tool is ideal for diagnosing heavy applications, so if your smartphone starts to slow down, go here and sort the list by memory, and it will instantly show the culprit, and for the average user, just monitor the list once a week.
Battery usage statistics as an indicator
Often users look for background apps to understand why the battery is going down quickly. In this case, the most effective tool is the built-in power statistics. Go to Settings → Battery and Performance (or simply “Battery”) and select the app consumption display.
And here you'll see not only active screen usage, but also background activity, and if an app that you haven't used all day displays a high percentage of consumption in the background, it's in hidden mode, which is typical of social networks, navigators and some live widget games.
By analyzing this list, you can identify programs that abuse rights, such as a flashlight or calculator should not have background activity, and if such an application is detected, it should either be removed or its rights in the privacy settings should be limited.
💡
Notice the apps that are labeled "Works in the background" and are a direct indicator that the process is not complete even after the window is closed.
MIUI also offers a Power Saving feature for individual applications, and by going to the settings of a particular application through the battery menu, you can choose a No Limits strategy (for instant messengers) or a Hard Limit strategy (for games and rarely used software), which is more effective than manually stopping processes.
Set up auto-start and MIUI restrictions
One of the key features of Xiaomi’s shell is its aggressive auto-run control system. Many apps try to sign up for auto-boot to be always ready to go, and you can manage this list through the Security app → Permissions → Auto-Start app.
Here is a complete list of programs that start with the operating system. It is recommended to leave auto-run only for messengers (Telegram, WhatsApp), alarm clocks and antiviruses. All other applications, especially stores, games and news aggregators, it is better to turn off.
☑️ Optimizing auto-start
In addition to autostarting, it is important to set background activity limits. In the same application, Security, there is a Battery section, where you can adjust the behavior of the system when you lock the screen. To maximize energy savings, you can set up a memory cleanup immediately after locking, but this can lead to loss of notifications from some applications.
Also worth paying attention to is the Advanced Cleanup feature, which allows you to set up automatic closures of applications that have not been used for a certain time.It is a useful tool for devices with a small amount of RAM (3-4 GB), but on flagships with 8-12 GB of RAM it is better to turn it off for smoother multitasking.
Hidden opportunities through ADB and debugging
For users who don't have enough regular resources, there are ways to analyze through a computer and debug via USB. Connecting your smartphone to your PC and activating debugging mode allows you to access the system logs in real time, which allows you to see not only the processes that are running, but also the frequency of their wake-up (wakelocks).
Using the adb shell dumpsys meminfo command, you can get a very detailed report of the memory allocation across all processes, which is difficult for beginners, but gives the most accurate picture, and you can see which application or library holds the memory and prevents the system from going into deep sleep.
adb shell dumpsys meminfo | grep -E "Total|Native|Dalvik"Another powerful tool is the adb shell ps command, which displays a list of all processes with their PIDs, which can force a process to be completed that is not removed by standard means, although it should be done with extreme caution.
What are Wakelocks?
Using ADB also allows you to disable embedded system applications that cannot be removed in the usual way. Many of them (such as Mi Credit analytics or Mi Video) can work in the background.
Comparison of Process Management Methods
The choice of control method depends on your goals: fast optimization or deep diagnostics. The table below compares the main ways to view and manage background applications on Xiaomi devices.
| Method | Difficulty | Informativeness | Risk to the system |
|---|---|---|---|
| Task Manager (swipe) | Low. | Low. | Minimum |
| Developer menu | Medium | Tall. | Medium. |
| Battery statistics | Low. | Medium | Minimum |
| ADB/Logs | Tall. | Maximum | High-pitched |
For most users, the best combination is to use battery statistics to identify problems and a developer menu for periodic monitoring. Deep customization through ADB is recommended only for experienced enthusiasts who understand the consequences of their actions.
⚠️ Warning: Task killing damages lithium polymer batteries more than their background work, as it causes the processor to constantly exit energy-saving modes.
Modern versions of Android and MIUI are smart enough to manage memory on their own. User intervention should be point-based and grounded in specific problems, not a regular habit.
