Launch in the background on Xiaomi: a detailed explanation and settings to optimize the smartphone

Have you ever noticed that some apps on your Xiaomi continue to work even after you shut them down? or wondered why the battery runs out faster than expected, even though you barely used your phone? All this is related to the concept of “start in the background”**, a mechanism that allows programs to perform tasks regardless of whether they are active on the screen or not.

On Xiaomi smartphones (especially those with MIUI or HyperOS shells), background management is implemented in a special way, on the one hand, saving battery power and system resources, and on the other, it can lead to unexpected consequences, from missed notifications to sudden closure of applications. In this article, we will discuss what background launch is, how it works on Xiaomi devices, and how to properly configure it to balance performance and autonomy.

It’s important to understand that Xiaomi is actively optimizing the background of apps through built-in tools like Battery and Performance or Special Permissions. But not everyone knows how these settings affect everyday phone use. Next, we’ll look at the key aspects that will help you take control of the background.

What is a “start in the background” and why it is needed

The term background execution refers to the ability of an application to perform tasks when it is not in the foreground.

• 🔔 Receiving notifications (such as messages on WhatsApp or Telegram).
• 🔄 Synchronization of data (mail, cloud services, social networks).
• 📊 Activity tracking (fitness trackers, pedometers).
• 🎵 Playing music or podcasts (for example, on Spotify or YouTube Music).

Without the background launch, many smartphone features would simply stop working. For example, if Google Maps could not work in the background, navigation would be interrupted each time you switch to another application. However, Xiaomi, like other manufacturers, limits background activity to extend battery life and prevent the processor from overheating.

In practice, this means that the system can force the closure of applications that consume too much resources in the background. For example, if you haven't opened Facebook in a long time, MIUI can freeze its processes to save charge.

How Xiaomi Manages Background Processes: MIUI vs HyperOS

Xiaomi smartphones use two main shells: MIUI (for most models) and HyperOS (the latest development, which debuted in 2023-2026).

In MIUI, the Battery and Performance module is responsible for optimization, which automatically allocates resources between applications.

1. Balanced – Standard mode that limits background activity to save charge.
2. Performance – allows more background processes, but puts the battery down faster.
3. Charge saving – aggressively closes background tasks, which can lead to notification delays.

HyperOS has made optimization algorithms smarter: it analyzes user habits and adapts background work to suit them. For example, if you use Instagram often in the morning, HyperOS will keep it active so that notifications come without delay. However, even here there are limitations — especially for applications that consume a lot of power (for example, games or video editors).

If you use a smartphone on MIUI, you’ll likely have to look more often at settings to exclude important apps from optimization. HyperOS requires less of this, but you won’t be able to completely avoid manual settings — especially if you use instant messengers or fitness trackers.

To check which shell is installed on your Xiaomi, go to Settings → The phone. → Version. MIUI/HyperOS.

What applications can and can not be turned off in the background

Not all background processes are equally useful. Some applications really need constant work, while others are wasting their power.

• ✅ Allow background launch: 💬 Messengers (WhatsApp, Telegram, Viber) – to prevent missing messages. 📧 Mail (Gmail, Outlook) – for timely receipt of letters. 🏃 Fitness trackers (Google Fit, Mi Fitness) – for correct calculation of steps and activity. 🎵 Music services (Spotify, YouTube Music) – for playback in the background.
• ❌ We can turn it off: 🎮 Games – they rarely need background work (except online games with notifications). 🛒 Store apps (AliExpress, Wildberries) – they only send out ads. 📺 Social Media (TikTok, Facebook) – if you don’t need instant notifications. 🔧 System utilities (such as Clean Master) – they often work idle.

Special attention should be paid to applications that are self-added to the startup. For example, some games or services (UC Browser, APUS Launcher) can run when the phone is turned on and consume resources in the background. To check the autoboot, go to:

Settings → Applications → Application Management → Autoboot

⚠️ Warning: Disabling background start for system applications (e.g. com.miui.securitycenter) can cause the phone to run unstable. Do not change settings for processes with names like android. or miui. without a clear understanding of their function.

Step-by-step: how to set up a background start on Xiaomi

If you notice that important notifications arrive late or apps spontaneously close, try configuring them manually. MIUI HyperOS:

Open Settings → Applications → Application Management

Select the desired application (such as WhatsApp)

Press the Battery → Start in the background

Enable the option to Allow Launch in the Background

Return and select Special Permissions → Autostart and Show Pop-ups

Restart your phone to apply changes-->

For some applications (such as instant messengers), it is also helpful to disable battery optimization:

1. Go to Settings → Battery and Performance → Battery Consumption Management by Apps.
2. Find the app in the list and select No Limits.
3. Save the changes.

If notifications do not come after these actions, check:

• 📵 Do Not Disturb Mode: It can block notifications. Disables in Settings → Sound and vibration → Don't disturb.
• 🔕 Notification permissions: go to Settings → Notifications and status bar → Manage notifications and make sure all switches are on for the app.
• 🔄 Sync: For Gmail or Contacts, check your sync settings in your Google account.

⚠️ Note: Some Xiaomi models (e.g. Redmi Note 12 or X-ray) POCO X5) After upgrading to HyperOS, the path to background startup settings may be different. If you don't find Start in the background, try searching through the search bar in Settings for Background».

Frequent problems and their solutions

Even after setting up the background launch properly, Xiaomi users may face typical problems, and consider the most common ones and how to fix them.

1. Notifications come with a delay

If messages on Telegram or WhatsApp only appear after opening the application, the reason is usually due to aggressive MIUI optimization.

• Check the Start-up in the background and Auto-Run settings (see instructions above).
• Turn off the Adaptive Battery in Settings → Battery and Performance → Battery settings.
• Add the application to Without Limits in Battery Consumption Management.

2.Applications are closed spontaneously

If a game or program closes when switching to another window, the MIUI memory cleanup mechanism is to blame.

• Enable Lock in memory for the application (in some firmwares this option is hidden – use the search by settings).
• Set Performance in Settings → Battery and Performance → Performance Mode.
• For games, turn on Game Turbo Mode in Settings → Special Features → Game Turbo.

3. Rapid battery discharge due to background processes

If your phone is running too fast, check which apps are using the most power:

1. Go to Settings → Battery and Performance → Battery Use.
2. Look at the consumption chart for the last 24 hours.
3. For “gluttonous” apps (like Facebook or TikTok), limit background activity or turn off auto-start.

Hidden Settings: How to Deeply Optimize Background Processes

For experienced Xiaomi users, there are additional background management tools that are not visible in the standard interface.

1. Developer Mode and Process Limitation

By activating the developer mode, you will get access to the advanced settings:

1. Go to Settings → About phone and 7 times click on the MIUI version.
2. Back to Settings → Additionally. → For developers.
3. Find the option to limit background processes and set the value of No background processes (or Maximum 2 process for balance).

This will forcefully limit the number of applications running simultaneously in the background, which will positively affect performance and autonomy.

2.Using ADB for deep optimization

If standard settings don’t work, you can use ADB (Android Debug Bridge) to disable battery optimization for specific applications, for example, to exclude WhatsApp from optimization, do:

adb shell dumpsys deviceidle whitelist +com.whatsapp

For this:

1. Install ADB on your computer (instructions are available on the XDA Developers website).
2. Connect the phone to the PC and allow debugging over USB.
3. Enter the command above in the terminal.

⚠️ Attention: Misuse of the right ADB Do not change the settings for system applications without a clear understanding of the consequences.

3. Alternative launchers for background task management

Some third-party launchers (like Nova Launcher or Lawnchair) allow more flexibility in managing background processes, and they do not replace MIUI system settings, but can further optimize application performance.
