Xiaomi, Redmi and Poco smartphone owners often face aggressive system optimizations: Messengers stop sending notifications, music is interrupted when the screen is turned off, and activity trackers reset data. This is not a bug, but a feature of the MIUI shell or the new HyperOS, which seeks to keep the battery power at all costs.
To solve the problem, you need to manually configure the rules for each important software, the system does not trust third-party programs and forcibly kills processes that it considers inactive, the correct configuration of autostart and energy savings will allow you to run applications in the background without restrictions.
In this article, we'll take you through all the steps you need to keep your software running smoothly, you'll learn to bypass system constraints and adjust notifications so that no message is lost, and deep tuning will take just a few minutes, but save you a lot of nerves in the future.
Why Xiaomi is closing apps in the background
Aggressive memory management is the hallmark of China’s Android shells. Xiaomi engineers are setting up the system to clear RAM from background tasks as quickly as possible. It’s useful for light games or video players, but it’s harmful for messengers and navigators.
The main culprit is a special system service that monitors the activity of running programs. If you fold an application and do not interact with it for a few minutes, MIUI marks it as "discharge" and stops the process, this is done to increase battery life.
In addition, there is a strict licensing binding in the system, and some Google services may not work properly without manual permission activation, and the user must explicitly indicate to the system that a particular program is important and cannot be completed.
⚠️ Attention: After each firmware update, the energy saving settings may be reset to factory values.
Understanding the operating system logic helps you find the switches you want faster, so you don't have to be a programmer, you just have to know where the main controls are.
Set up auto-start for stable operation
The first step to solving the problem is to activate autorun. Unlike pure Android, in the shells from Xiaomi, this option is put into a separate menu and by default is often disabled for third-party software.
To find the menu you want, go to Settings → Apps → Auto Run. This will show you a list of all the programs installed. You need to find the right app and activate the slider opposite it. Without this step, further settings may not have an effect.
The system can request permission to make changes. This is the standard security procedure of HyperOS. Confirm the action, and the program will be authorized to run with the operating system after restarting the device.
☑️ Checking auto-start settings
Don't start auto-run for all programs in a row, it will lead to lower performance and quick battery discharge, and choose only those services that need to work all the time: messengers, mailboxes, smart home.
Power management and battery saving
The most important step is to set up the power policy, and that's where the master switch is hidden, which prevents the system from killing the process, and without changing that, the app will close as soon as the screen is turned off.
Go to Settings → Applications → All apps. Find the program you want and click on Energy Saving. The default is "Battery Savings," which is causing the problems. You have to select No Limits.
This setup gives the program full access to the CPU and network resources in the background, the system will stop interfering with its operation, and for instant messengers like Telegram or WhatsApp, this is a critical parameter.
💡
If you can’t find the “Energy Saving” item in the app menu, try opening “Application Info” through a long tap on the desktop icon.
It is sometimes useful to reset the battery usage statistics for a particular application if the settings do not apply. This can be done on the same menu by selecting the data cleanup point, but be careful: this can remove the local program settings.
Memory retention and multitasking
An additional protection measure is to lock the application in the menu of running tasks, which prevents the system from automatically clearing the memory even if it is crowded, and is especially effective on devices with a small amount of RAM.
Open the menu of running applications (a swipe from bottom to bottom with a delay or a menu button). Find the window of the desired program. Pull the application card down (or click on the lock in the corner, depending on the version of the launcher), a lock icon will appear, meaning that the task is closed.
Now, even if you click the Clear All button, this app will remain in memory, which guarantees instant re-runs, but remember that this takes up some of the RAM all the time.
| Protection method | Efficiency | Impact on the battery | Necessity |
|---|---|---|---|
| Auto-start | Tall. | Low. | I'll be sure. |
| No restrictions. | Critical | Average. | I'll be sure. |
| Lockdown (Castle) | Medium | High. | Recommended |
| Permits | Basic | Low. | I'll be sure. |
If the application crashes anyway, check for system updates, as new security patches may change the algorithms.
Advanced Notification and Permission settings
Sometimes the problem isn't energy saving, but not the right to display notifications or access the network, and MIUI has a separate notification manager that can block pop-ups.
Go to Settings → Notifications and Status bar → Notification management. Make sure that all types of alerts are turned on for an important application: pop-up, notification center, and lock screen. Also check Sound and Vibration.
Pay special attention to permissions. Search the Permits section in the app menu. Make sure you have access to geolocation (if necessary), microphone and, importantly, autorun. Without autorun rights, background work is not technically possible.
⚠️ Note: Do not give applications of dubious origin extended access rights.
Some services, such as health tracking or navigation, may require permission to operate in the background even when the screen is off, a separate item in the permissions that sometimes needs to be manually activated.
Specifics of work in HyperOS and new versions of MIUI
With the release of the HyperOS shell, memory management algorithms have become even more complex, with the introduction of the memory extension feature, which uses part of the storage as a virtual RAM, which can slow down background applications, since the read speed from flash memory is lower than that of RAM.
The new versions have Smart Windows and a more aggressive notification grouping, so if the app is unstable, try turning off the Memory Extension feature in the About Phone section, which will free up real resources for background tasks.
HyperOS has also changed the way to some security settings, and now they are more often grouped into the Security app» → «Battery. The interface has become more visually rich, but the essence has remained the same: you need to find a specific application and remove the restrictions from it.
Secret team for diagnosis
Users of new smartphones should pay attention to the settings 5G. If the network is unstable, the application can constantly try to reconnect, using up the charge and going to sleep. 4G/LTE.
To sum up, the stable operation of applications in the background on Xiaomi requires a single, but careful setup. You need to go through the chain: Autorun → Energy Saving (No Limits) → Memory lock. Observance of these rules ensures that important notifications will arrive on time, and the music will not be interrupted in the middle of a word.
💡
The key is to set the "No Limits" mode in the energy saving section of a particular application, and without that step, the rest of the settings may not work.
