Xiaomi smartphone owners often face a paradox: messaging from messengers comes with a delay, and the navigator goes out when the screen is turned off. The blame for all the aggressive optimization of the MIUI system, which ruthlessly “kills” the processes that work in the background. Understanding how the background mode works is the key to turning your device into an obedient tool, not a source of constant irritation.
Many users mistakenly believe that swiping apps completely stops them from working. In fact, the Android operating system is more complex, and simple swiping often removes the shortcut from memory, leaving services active. However, on Xiaomi smartphones, an additional layer of battery protection comes into force that requires a special approach to configuration.
In this article, we will take a closer look at the mechanics of background processes, learn how to distinguish useful services from energy eaters, and set the system up to work exactly as you want it to, and learn why standard settings are often too rigid and how to skirt them correctly without losing autonomy.
Mechanics of background processes in MIUI
Background mode is a state in which the application is not displayed on the screen, but continues to perform certain tasks. In the Xiaomi ecosystem, a special service is responsible for managing these processes, which monitors the activity of each software that is running, and if the system decides that the application has not been used for a long time and is not critical, it will force the application to terminate its work to save battery power.
The main problem is that aggressive optimization algorithms can’t always tell the difference between an important background process and a garbage one. For example, a navigator or activity tracker needs to read GPS data constantly, but the system may see this as excessive power consumption, which results in a notification that the application is stopped, or you simply stop receiving updates in real time.
It is important to understand the difference between a frozen state and a full stop. When an application is frozen, it takes up RAM space but does not use CPU time. When it is completely stopped, the process is removed from memory, and it will take time and resources to run it. Xiaomi smartphones with the MIUI shell and HyperOS have the default Ultra-energy Saving mode for all new applications, which often blocks their operation in the background.
⚠️ Warning: Forced shutdown of system applications through settings can lead to unstable interface performance or loss of communication with update servers.Be careful when managing Google services and system components MIUI.
Modern versions of the shell require the user to explicitly prioritize. Unless you set the rules manually, the system will follow a pattern that may conflict with your gadget usage habits, especially for users who rely on Xiaomi smartphones to operate or control a smart home.
Set up auto-start and permissions
The first step to managing the background is to set up autoruns. Unlike standard Android, where apps start as needed, MIUI has a separate switch that allows the program to run with the system, and without that permission, many messengers won't be able to receive messages until you manually open them.
To access these settings, you need to go to the security menu. The path usually looks like: Settings → Applications → Permissions → Autorun. Here you will see a list of all installed programs. It is recommended to enable autorun only for those applications that should be running constantly: messengers, email clients, alarm clocks and health trackers.
Beyond auto-run, a critical parameter is the permission to run in the background. Even if auto-run is allowed, the system can limit the activity of the application after you fold it. To avoid this, find the desired application in the list of installed, click on "Battery Savings" and select the option "No restrictions." This will give the application the green light for resource use.
You don't want to include this option for all programs in a row, and if you allow background activity for games or video editors, it can significantly reduce battery life without any apparent benefit, and selective approach is the key to balancing functionality and autonomy.
☑️ Configuring priority applications
Memory management and application consolidation
Another effective way to keep important processes active is to keep them on the menu of recent tasks, and when you attach an application, the system receives a signal that cleaning up memory should not affect this process, even if free RAM becomes critically scarce.
To secure the application, open the running task menu (a swipe from the bottom up with a delay or a menu button) and pull the application card down (or click on the lock icon, depending on the MIUI version). Next to the icon, a lock symbol will appear, meaning that the application is protected from unloading.
But remember, anchoring is not an absolute guarantee. If the system needs to release resources to run a heavy application or game, it can still complete the background process, although it will do so last, so it is best used in conjunction with setting the battery constraints.
| Management method | Impact on the battery | Reliability of work | Recommended application |
|---|---|---|---|
| Auto-start | Low. | Average. | Messengers, alarm clocks. |
| Removing battery restrictions | Medium/High | High. | Navigation, trackers, smart home |
| Retention in memory | Depends on the app. | Average. | Frequently used programs |
| Background activity resolution | High. | Maximum. | Specialized software |
Using all three methods simultaneously for one application creates the most reliable configuration, for example, for an application Mi Fit or Zepp Life, synchronizing data with a fitness bracelet, you need to apply all of these settings, otherwise synchronization will occur only when you open the program.
Battery optimization and energy saving modes
Xiaomi has several levels of energy saving, each affecting the background differently. Standard mode tries to find a balance, but often leans toward savings. Ultra-energy saving mode turns a smartphone into a simple “bell ringer”, completely blocking the background activity of most applications.
Users who want to keep notifications running smoothly are encouraged to turn off Advanced Optimization from the battery menu, open the Security app, go to Battery, click three dots in the corner, and select Settings, and then find Advanced Optimization and deactivate it.
Also worth noting is the Sleep in Your Pocket feature and other smart modes that can lock the screen and limit the network when the phone is in the dark or in the bag.While these features are convenient, they can interrupt file downloads or navigation if the phone is in the bag.
Regular monitoring of battery consumption statistics helps to identify "gluttonous" applications, if you see a program that was not used, but it consumed 15% of its charge per night, then it is not working in the background correctly, in which case it is better to reset its settings or delete it if it is not system.
⚠️ Attention: Disabling battery optimization for a large number of applications can cause the smartphone to start to discharge much faster, especially in standby mode. 1-2 day after the modification.
Solving Notification and Synchronization Problems
A common problem with Xiaomi users is the lack of notifications from Gmail, Outlook or corporate email, which is because Google’s standard push notification mechanism sometimes conflicts with MIUI. To solve this problem, you need to add the app to the exclusion list.
In addition to setting up the battery, check the notification settings for a particular application, make sure that the "Show lock screen", "Sound" and "Pop-up notifications" are enabled, and sometimes the system flags the notifications as "low-value" and hides them if you rarely interact with them.
For instant messengers like Telegram or WhatsApp, stability of the Internet connection in the background is also important. Make sure that the Wi-Fi settings do not include the “Sleep Wi-Fi Disconnect” feature if you are often in areas of poor cell reception, which will allow the phone to switch to mobile Internet without breaking the connection.
In some cases, cleaning the cache of Google Play Services helps. Go to Settings → Apps → All apps → Google Play Services → Memory → Clear the cache. This will not delete your data, but can update notification delivery mechanisms.
Additional tools and Developer Options
For advanced users, you can fine-tune it through the Developer Menu, and you can activate it by clicking 7 times on the version number in the About Phone section, and you can find options that affect background processes in the menu that opens.
The "Background Process Limit" item deserves special attention. It can be set to a standard value by default, but some users accidentally change it to "No background processes," which completely breaks multitasking. Make sure that the "Standard Limit" value is here.
Also on this menu is the “Do not turn off screen when charging” feature, which can be useful if you use your phone as a display or navigator in your car, but for everyday use, it is best to keep it off to avoid burning out the screen.
Using third-party memory management applications on Xiaomi is strongly discouraged: built-in MIUI mechanisms work more efficiently, and external cleaners can only provoke the system to more aggressively close processes, creating a cycle of constant reboot of services.
