Owners of Xiaomi, Redmi and POCO smartphones often face a situation where messengers stop sending notifications and the navigator turns off when the screen is locked. Background mode is the operating system mechanism that allows applications to perform tasks without active user participation. In the shell of MIUI and the new HyperOS, this process is aggressively optimized to save battery power.
Understanding the basics of background processes is essential for anyone who wants to make the most of their device. Xiaomi is famous for its power-saving algorithms, which by default can be too strict. If you want a fitness tracker to count steps and an email client to instantly alert you about emails, you will need to manually configure the system.
In this article, we'll look at how to control the behavior of programs to find a balance between autonomy and functionality. You'll learn to distinguish between system limitations and the settings of the applications themselves. It's critical to understand the difference between freezing an application and completely banning background activity, because the consequences of these actions are radically different. Let's dive into the technical details of how your smartphone works.
What is the background mode and why it is needed
Background mode is a state in which the application is running but not displayed on the screen and is not in the focus of the user's attention. The Android operating system on which MIUI operates, allocates CPU and RAM resources between active and background tasks, which allows the music player to continue playing while you browse the social media feed.
But the back-end functionality goes far beyond media: Messengers use background services to receive real-time push notifications; navigation apps continue to build routes and voice cues even when the screen is dead; without that mode, the smartphone would become a device that requires constant visual monitoring.
⚠️ Warning: Completely shutting down background activity for Google or Xiaomi system services can lead to unstable phone performance, loss of contact sync and Play Market store failure.
There are several types of background processes that consume device resources:
- 🔔 Push notifications: waiting for incoming messages from the server.
- 📍 Geolocation: Periodic coordinate determination for maps or trackers.
- 🔄 Synchronization: Updating email, cloud storage and calendar data.
- 🎵 Media playback: streaming audio or video.
Managing these processes is key to personalizing your Xiaomi Redmi. By default, the system tries to complete any “heavy” processes to extend battery life.
Features of battery optimization in MIUI and HyperOS
Xiaomi’s shells are known for their aggressive energy-saving policies, and unlike pure Android, it has an additional layer of control called Battery Saver and a system task manager, which automatically kill processes that algorithms believe are not in use at the moment.
The problem is that algorithms don't always understand the user's needs, for example, if you listen to a podcast through your browser in the background, the system can deem the tab inactive and stop playback after 10 minutes, which often causes bewilderment among owners of Redmi Note and POCO X series.
To combat this, you have a special section in your settings that allows you to set priorities, so you can manually tell the system which apps should work without restrictions, and this is especially true for instant messaging apps like Telegram or WhatsApp, where instant messaging is important.
With new versions of HyperOS, the logic of the work has become even more complicated, the system analyzes usage patterns and can automatically limit rarely used programs, so periodic checking of settings becomes a mandatory procedure for comfortable use of the smartphone.
How to allow applications to work in the background
To make sure an important application works, you have to add it to the exclusion list, and this is done through the battery settings of a particular application, which takes less than a minute, but solves 90% of the notification problems.
Follow the step-by-step instructions for setting up:
☑️ Permit settings
- Open the settings of your device.
- Go to the Appendix section → All Appendices.
- Find the desired program in the list (for example, a navigator or messenger).
- Click on the item Saving battery.
- Select the option No restrictions.
After that, the system will stop forcibly completing the process of this application, and it is also worth checking whether you have permission to Autorun. If this switch is turned off, the application will not be able to start its background services after restarting the phone.
⚠️ Warning: No Limits Mode increases battery consumption, and it is not recommended to apply this setting to all installed games or entertainment applications.
For some system services, the path may be different, for example, to adjust the screen in navigation mode, you sometimes need to additionally enable the option “Do not turn off the screen” in the special features or the map settings themselves.
Autostart and Background Process Management
The AutoStart mechanism in MIUI works regardless of the standard Android settings. Even if you allow it to work in the background, without the autostart enabled, the app may not start its service after cleaning up memory or restarting. This is a common reason why the alarm clock does not ring or the smart home loses communication.
Autostart control is in the hidden security menu. To get there, open the Safety app (green zipper icon) that is pre-installed on all Xiaomi smartphones. At the bottom of the screen, look for the "AutoStart" option.
Here is a list of all programs that can run with the system.
- 📱 Messengers: to receive calls and messages.
- ⌚ Apps for wearables: Mi Wear, Zepp Life, Galaxy Wearable.
- 🏠 Smart home: Mi Home, Yandex, if you have smart devices.
- ☁️ Synchronization: if you are actively using cloud services.
Other applications, such as stores, games or photo editors, are best kept off, and they will run themselves when you open their icon, and will not waste resources.

Comparison of energy saving regimes
Redmi and Xiaomi have several levels of background restriction, and understanding the difference between them can help you flexibly adjust your device to your current tasks, such as having tight restrictions on travel and soft ones on workdays.
Let’s look at the main modes in the table below:
| Regime. | Influence on background processes | Impact on notifications | Recommendation |
|---|---|---|---|
| No restrictions. | Full work. | Instantly. | Messengers, alarm clocks. |
| Battery savings | Limited. | Delay or disconnection | Everyday use |
| Super-economy | Prohibited. | Just calls and calls. SMS | Critical charge (< 10%) |
Super-savings turns your smartphone into a bell ringer, turning off the internet and background sync for most applications, which is useful when you don’t have chargers on hand and you have to wait for an important call.
💡
Use In-Airline mode in conjunction with Wi-Fi on if you're in a bad cell signal zone, and searching the network in the background consumes up to 40 percent of the battery per hour.
Switching between modes is done through the top notification curtain or in the Settings → Battery menu. It is convenient to add a mode switching widget to the desktop for quick access.
Diagnostics and troubleshooting background work problems
If the settings are correct, but the application still does not work in the background, the reason may lie in a version conflict or cache overflow. Often, simple cleaning of the application data or reinstallation helps. It is also worth checking whether the phone is not a third-party memory cleaner that can conflict with Xiaomi system algorithms.
For advanced users, monitoring is available through ADB. Using the adb shell dumpsys battery command, you can see which processes consume the most energy, which will help to identify the “hidden eaters” of the battery, which masquerade as system.
adb shell dumpsys package com.whatsapp | grep "wake lock"This command will show if WhatsApp holds a wake lock, which indicates active background activity. If you see persistent wakelocks from unknown apps, you better remove them.
⚠️ Note: Using third-party apps to “accelerate” or “cool” your phone on modern versions of Android often does more harm than good, as they are constantly hanging in the memory.
In difficult cases, when background services are not behaving properly, you may need to reset your network settings or completely reset to factory settings.Be sure to back up your data via Mi Cloud or Google Drive before doing so.
💡
The stable operation of background applications on Xiaomi is achieved by balancing the system limitations of MIUI and manual permissions for specific programs.
