Users of Xiaomi, Redmi and Poco smartphones often face a situation where important notifications do not arrive on time or apps abruptly close after folding.This is due to aggressive optimization of the MIUI and HyperOS system, which seeks to maximize the battery life of the device. Understanding what it means to launch in the background, becomes the key to solving problems with the functionality of the gadget.
Device owners need to be clear about the difference between normal operation and background to properly configure their device. Launching in the background on Xiaomi allows the application to run without an active window on the screen, continuing to perform tasks and transmit data. Without the right configuration, the system can forcefully complete these processes, considering them to be an extra load on the battery.
In this article, we will take a closer look at how the operating system works, explain how to manage auto-start and background processes, and provide step-by-step instructions for setting up, and learn to balance energy efficiency with the full operation of all the necessary services.
The basic concept of the background work of applications
Modern operating systems, including Xiaomi’s shell Android, use multitasking to ensure smooth interfaces. However, the background is not just an open application that you can’t see, it’s a complex process where the program continues to consume CPU and RAM resources to perform certain tasks.
When you fold a messenger or a navigator, the system doesn't always leave it active. Aggressive energy saving algorithms can freeze or shut down the process completely to save battery life, which is why users often complain about no notifications or stop downloading files.
It is important to distinguish between two types of processes:
- 📱 Active processes – applications that are on the screen right now and consume the maximum resources.
- 🕒 Background processes – programs that perform a limited set of actions (server listening, GPS-tracking, data loading) without displaying the image.
- 🧊 Frozen processes – a state where the application is stored in memory but completely deprived of access to the application. CPU before activation by the user.
💡
To check which apps are currently running in the background, use the built-in Statistical tool in your battery settings or third-party utilities like DevCheck.
Understanding this classification will help you prioritize your priorities, so if you let too many programs run in the background, the battery will run out faster, and if you stop everything, you will lose functionality.
Mechanism of MIUI and HyperOS with applications
The MIUI shell and the new HyperOS have their own add-on over standard Android, which tightly controls the launch of programs. The system uses a special service that tracks the behavior of each installed software. If the application is not on the exclusion list, it can be limited in rights.
The key here is autorun, which is the permission that gives the application the right to start right after the phone is turned on or after another process is completed, and without that permission, many programs will not be able to work properly in the background, because the system will simply not allow them to start after cleaning the memory.
There's also the concept of a floating window, or Picture-in-Picture, which also refers to background tasks, but with visual display. However, the classic background mode hides the interface, leaving only functionality.
System limitations are particularly noticeable on models with a small amount of RAM, where memory cleaning is more frequent, and background processes are completed first, and users of the budget models Redmi and Poco should pay even more attention to the setup.
Instructions for setting up autostart and background work
To ensure that the required applications work consistently, you need to manually make changes to your security settings. Standard settings are often too stringent for instant messengers, email clients, and activity trackers.
Follow the following steps to activate full access:
- Open the Safety app (green icon with lightning).
- Go to the Application Permissions or Permissions section.
- Find the Auto Start item and turn on the switch opposite the desired program.
- Go back to the main permissions menu and select Other permissions.
- Find your app and resolve all the items, especially “Mastering on top of other apps” and “Background Launch.”
☑️ Checklist of application settings
You should also check the settings of the battery itself. Go to Settings → Applications → All applications, select the desired one and find the Battery section (or “Energy consumption”). Set the value No limits. This is a critical step that is often ignored.
Once you do this, the system will stop forcing the software to close, but remember, this will increase the charge consumption.
Energy management and battery optimization
By allowing background work, you sacrifice some autonomy. Xiaomi offers several power saving modes that may conflict with your permission settings. For example, Ultra or Full Energy Saving mode blocks most background processes regardless of individual settings.
To balance performance and operating time, use smart scenarios, and you can set up automatic power saving at night or low charge, leaving full functionality in the daytime.
⚠️ Warning: Setting “No Limits” mode for navigators or video players can cause the battery to run out quickly and the housing to heat up as they will be constantly using it. GPS screen.
Also worth considering is the impact of desktop widgets, which are also background processes that keep data updated, and turning off redundant widgets is an easy way to reduce the load on the system without losing functionality to the core applications.
A comparison of the effect of different battery settings is presented in the table below:
| Setting up | Impact on the battery | Impact on notifications | Recommendation |
|---|---|---|---|
| Auto-start is off. | Minimum | Notifications may not be coming | Turn it off for games |
| No restrictions. | High. | Instant notifications | Enable messengers |
| Limited background | Average. | Delayed arrival | For social media |
| The ultra-economy regime | Critically low. | Blocking the majority | Only when discharged. |
💡
The optimal strategy is to allow background work only for 5-7 key applications (messaging, mail, alarm clock), leaving the rest under control of the system.
Solving Notification and Synchronization Problems
If notifications don’t come even after you set up autorun, the problem may be deeper system constraints, and some versions of MIUI have a hidden mechanism for “freezing” long-unused applications.
Check if Advanced Optimization is enabled. It's in the Developer Menu. To get there, you have to click on the build number several times in the About Phone section. In the developer menu, find the Enable MIUI Optimization item and try to turn it off (reboot required).
Also make sure that the notification service itself (like Google Play Services or Mi Push) is also allowed to run in the background, and without the basic push notification delivery service, individual apps won’t be able to notify you.
⚠️ Attention: Disabling optimization MIUI This can cause some interface elements to be displayed incorrectly or increase battery consumption globally.
Often, simply reinstalling a problem application after resetting all permission settings helps, allowing the system to re-register the necessary access rights.
What to do if notifications are missing after the update?
Specificity of the work of messengers and social networks
Messengers like Telegram, WhatsApp and Viber require a constant connection to the server, and for them, the background is life, and if the system restricts their work, messages will only come after the application is opened.
Unlike games or tools, social media doesn't have to work in the background all the time unless you need instant notifications, you can leave standard restrictions on them, which saves you charge, but if you use your phone for work, you'd better be safe.
In some cases, switching the network type in mobile Internet settings helps, try setting your preferred 5G/4G/3G/2G (auto connect) network type to provide a stable channel for background data transfer.
Diagnostics and monitoring of background processes
For advanced users, detailed statistics are available. In Settings → About Phone → All options can be found information about uptime and running services. Also useful is the section Advanced Settings → For developers → Process Statistics.
Here you'll see which apps are consuming the most resources in the background, and if you see an unknown process that is putting a lot of stress on the system, that's an excuse to check the phone for malware or remove the recently installed dubious apps.
Regular monitoring keeps the system clean, periodically check the auto-start list and remove programs that you have stopped using daily.
⚠️ Note: Do not disable system processes with names that contain System, Android», «MIUI» It can cause the phone to malfunction or cyclic reboot.
Using third-party memory cleaners often harms more than it helps, as they forcefully shut down processes that the system immediately tries to reopen, consuming the processor’s life.
💡
Use the “Access” function in the recent task menu (swipe down the application preview) to prevent an important application from accidentally closing when you clear memory.
Final recommendations for setting up
Smart background and autorun settings on Xiaomi are about finding a personalized balance. There is no universal setting that works for everyone. Large battery models can have more processes, compact models can have more economy.
The rule is, you can only customize what you really need, you can't give full rights to all the games and utilities you've installed, and you can only leave "No Limits" for communication and important tools.
Following these guidelines, you will turn your smartphone into a reliable tool that will always be connected without discharging in a couple of hours.
