Launching in the background on Xiaomi: how it works and why you need it

If you’ve ever looked into the battery settings or task manager on a Xiaomi smartphone, you’ve probably come across the term “start in the background.” This feature often raises questions: why some apps continue to work after closing, how it affects the autonomy of the device, and whether it is possible to turn off background activity without harming functionality. In this article, we’ll take a closer look at what lies behind the “back start” in MIUI firmware, what processes apply to it and how to manage them correctly on models from Redmi, POCO and Xiaomi’s flagship 13/14 series.

The concept of background processes is not unique to Xiaomi — it is found in any modern Android smartphone. However, MIUI traditionally restricts background activity more aggressive than other shells to extend battery life. This leads to conflicts: some users are happy to save charge, others complain about “killed” notifications from messengers or unsynchronized data. We will help find a balance between performance and autonomy, and also tell you which applications should never be limited in the background – otherwise you risk missing important messages or calls.

What is a “start in the background” and how it works in MIUI

Background startup is the mode in which an application performs tasks after the user closes. For example, Telegram messenger can check new messages, and a music player can play tracks even if you folded an application. In MIUI, background activity is regulated at the system level and divided into three key types:

• 🔄 Autosynchronization of data: applications (mail, calendar, cloud services) periodically update information without your participation.
• 🔔 Push notifications: Messengers (WhatsApp, Viber) and social networks receive signals about new messages through Google servers or their own channels.
• ⚙️ Service processes: System utilities (e.g. miui.analytics) collect usage statistics or optimize performance.

The MIUI feature is a rigid restriction of background processes by default, which automatically freezes underused applications to save battery life, which causes some programs to stop showing notifications or synchronizing data until you manually open them again after you restart the device.

What apps are running in the background on Xiaomi

Not all programs are equally active in the background, and in MIUI, they can be divided into three categories:

It’s important to understand that even a “closed” application can consume resources. For example, Google Play Services often keeps up to 5-7 processes in the background for geolocation, updates and synchronization. To see the full list of active programs, go to Settings → Apps → Application Management → Run.

How to Check Which Apps Work in the Background

In MIUI, there are several ways to track background activity:

1. Task Manager: Swipe up from the bottom of the screen and hold your finger to open the list of running applications. This shows only the "curled" programs, but not all the background processes.
2. Battery settings: Go to Settings → Battery and Performance → Battery usage. Slip on the graph and select “Details.” Here you will see which applications were consuming energy in the background.
3. ADB-commands (for advanced): connect your smartphone to your PC and execute the command: adb shell dumpsys activity activities | grep "mFocusedActivity" This will show the current active task and part of the background processes.

For more detailed analysis, you can use third-party utilities like Greenify (requires root) or AccuBattery, which show how much time each application spent in the background and how much charge it spent.

💡

If you see an unknown high-consumption app (e.g., com.xiaomi.mipicks) in the Battery Use list, check it out through a Google search – it could be an ad module or a virus.

How to Disable or Limit Background Start

If you notice that the battery is going down too fast, you can manually limit the background activity of unnecessary applications. Here is a step-by-step guide for MIUI 14/15:

1. Open Settings → Applications → Application Management.
2. Select the appropriate app (such as Facebook).
3. Slip on the "Battery" (or "Permissions" if there is no item).
4. Select the restriction option: 🔋 Without restrictions – full background activity. ⚡ Optimized — MIUI It will limit activity at low charge. 🚫 Strictly limited – background start blocked.

To massively disable background processes, use UltraEconomies mode (Settings → Battery → Battery Modes) which automatically suspends all non-critical tasks, but can disrupt notifications.

What happens if you completely disable the background start

Shutting down background processes completely may seem like a good idea for saving battery life, but there are serious downsides to this approach:

⚠️ Note: If you block the background launch for Google Play Services, geolocation, automatic app updates, and sync of your Google account stop working, this can lead to errors in YouTube, Gmail, and other services.

• 📵 Missed Notifications: Messengers will stop showing new messages until you manually open them.
• 🔄 Unsynchronized data: Mail, calendar and cloud services (Mi Cloud, Google Drive) will not be automatically updated.
• 📍 Maps (Google Maps, Yandex.Navigator) will not be able to track your location in real time.
• 🔋 Paradoxical battery consumption: Some applications are forced to restart by the system, which consumes more energy than working in the background.

The best option is a selective restriction, for example, you can block the background launch for games and rarely used social networks, but leave it for messengers and navigators.

How to Optimize Background Processes to Save Battery

Instead of radically disabling all background tasks, it is better to use an integrated approach:

1. Set up autosynchronization: Go to Settings → Accounts and sync and turn off automatic sync for unnecessary accounts (e.g. Mi Account if you are not using Xiaomi services).
2. Use Adaptive Battery: In Settings → Battery → Battery settings turn on the option “Adaptive Battery.” MIUI will analyze your habits and limit background activity only for rarely used applications.
3. Disable unnecessary system services: Some processes (e.g. miui.daemon or com.xiaomi.finddevice) can be safely disabled via Settings → Apps → Show all applications → System (you need to unlock the bootloader).
4. Set up a schedule of restrictions: MIUI 14+ has a feature called “Settings → Battery → Schedule” (Settings → Battery → Schedule). You can set hours when background activity is limited (for example, at night).

For advanced users, there is another way to change the settings through ADB. For example, the command below disables background optimization for a particular application (replace com.example.app with your application package):

adb shell dumpsys deviceidle whitelist +com.example.app

💡

The safest way to save battery is to use built-in MIUI tools (adaptive battery, timetable constraints), rather than manually disabling background processes.

Frequent background start problems and their solutions

Xiaomi users often encounter common errors related to background processes, and here are the most common ways to fix them:

If the problem persists after the settings change, try resetting the app cache (Settings → Apps → Storage → Clear the cache) or reinstalling it. In extreme cases, resetting the settings to factory (don’t forget to make a backup!).
