Background mode on Android Xiaomi: what it is, how it works and why it is set up

Have you ever noticed how some apps on your Xiaomi continue to send notifications, update content, or even play music when you folded them?It works in the background — one of the key features of the Android operating system that allows programs to perform tasks in hidden mode. However, not all users understand how this mechanism affects smartphone performance, battery consumption and even privacy.

In this article, we will take a closer look at what the background mode is on Xiaomi phones (including Redmi models, POCO And Mi), how it differs from similar features on pure Android, and why setting it up can significantly improve the experience of using the device. MIUI.

What is the background mode on Android and why it is needed

Background mode is a state in which the app does not appear on the screen, but continues to perform certain operations. For example, messengers (WhatsApp, Telegram) check new messages in the background, music services (Spotify, Yandex Music) play tracks, and navigators (Google Maps, Yandex Maps) track your location. Without the background, these functions would not be possible.

However, the coin has a flip side: on Xiaomi smartphones, by default, many applications aggressively use background processes, which leads to accelerated battery discharge and slowdown of the system. MIUI, It's trying to guess which programs are important to the user and keeping them active.

• 📱 Main objectives of the background regime:
• 🔄 Content updates (social networks, mail, news)
• 🔔 Receiving push notifications
• 🎵 Media playback (music, podcasts)
• 📍 Location tracking (navigation, fitness trackers)
• ⚙️ Data synchronization (cloud services, backups)

It's important to understand that the background is not the same as caching (temporary storage to speed up work) or battery optimization (limiting application activity to save charge), these mechanisms are closely related, but work in different ways, MIUI It can close the application in the background, but leave its cache intact, or vice versa – let the program work hidden, but limit its access to the Internet.

How the background is implemented in MIUI: Features and differences of pure Android

Shell MIUI, Xiaomi installs on all its smartphones, significantly modifying the standard background Android mode, unlike the “bare” Android (for example, on the Pixel or Nexus), where the user controls the activity of the applications, MIUI Automatically manages processes through multiple mechanisms:

1. Auto-optimization: The system analyzes which apps you use more often and leaves them running in the background, while the rest pauses.
2. Whitelist: Some programs (such as Mi Fit or Mi Cloud) are added to exceptions by default and are always active.
3. Aggressive closure: if the application is not used for a long time, MIUI It can kill it completely, even if it is supposed to work in the background (for example, Viber stops showing notifications).

These features often cause user complaints, such as the fact that after updating, many people say that they are not the only ones who have been updated. MIUI Notifications from messengers or banking applications stop coming in, and the reason is that the background management policy is too tight. POCO-firmware POCO Launcher these restrictions are a little softer, but the principles of the work are the same.

Interestingly, new Xiaomi models (for example, Xiaomi 14 or Redmi Note 13 Pro)+) Background optimization algorithms are smarter, learning from user habits and making mistakes less often. A2 or POCO M6 Pro) these mechanisms are still operating in the old-fashioned manner, which is inconvenient.

What apps work most often in the background and why it’s bad

Not all programs are equally active in the background, some of them can consume up to 30 percent of your battery life per day, even if you're not using them.

• 💬 Messengers: WhatsApp, Telegram, Viber – constantly check new messages and synchronize chats.
• 📱 Social networks: Facebook, Instagram, TikTok – update the feed even when closed.
• 🎮 Games: PUBG Mobile, Genshin Impact – Some run background processes for event notifications.
• 📍 Navigators: Google Maps, Yandex Maps, 2GIS – track location to speed up launch.
• 🏦 Banking applications: SberBank Online, Tinkoff – check transactions and send push notifications.
• ☁️ Cloud services: Google Drive, Mi Cloud, Dropbox – sync files.

The problem is that many of these apps not only consume battery, but also:

• 🔋 The processor is loaded, which causes the phone to heat up.
• 📶 Use mobile traffic even when you’re connected to Wi-Fi.
• 🔒 They may collect data about your activity (for example, Facebook tracks your visited websites).
• ⚡ Slow down the system by occupying RAM.

For example, if you leave Instagram to work in the background on Xiaomi Redmi Note 12 Pro, he can eat before 15% charge-by-charge 8 And Google Maps, in location tracking mode, drains the battery even faster, before it's too late. 20-25% post 4-5 hours.

⚠️ Note: Some apps (such as Mi Fit or Zepp Life) are specifically optimized to work on Xiaomi and may ignore the standard background restrictions. If you don't use fitness trackers, it's best to turn them off completely in the settings.

How to check which apps are active in the background on Xiaomi

Before you set up the background, you need to understand which programs are consuming resources. MIUI There are a few built-in tools:

1. Battery Monitoring: Go to Settings → Battery and productivity → Battery usage. Slip on the last 24 hours of consumption. Select the App tab, which shows the programs that used up the charge in the background.
2. Task Manager: Open Settings → Annexes → Task Manager. In Active, you'll see a list of apps that are currently running in the background.
3. Special permissions: Go to Settings → Annexes → Permit management → Special access → Background work: This shows programs that are allowed to perform tasks without restrictions.

For more detailed analysis, you can use third-party utilities like AccuBattery or Greenify to show not only the battery life, but how often apps wake up in the background, for example, AccuBattery can detect that Facebook is activated every 10 minutes, even if you don't use it.

On the new versions MIUI 14/15 (For example, on Xiaomi. 13T or Redmi K60) There's an additional section called "Intelligent Optimization in Battery Settings," where the system shows you what applications it thinks are "important" and keeps active. Often, this list includes unnecessary programs that can be manually removed.

Step-by-step: how to limit the background mode on Xiaomi

If you notice that the battery is running out too quickly or the phone is slowing down, it’s time to set up the background mode. Here are 4 main ways to limit the activity of applications:

1. Disabling background activity for individual applications

The most point method is to prohibit work in the background only for unnecessary programs:

1. Go to Settings → Applications → Application Management.
2. Select the application you want (such as TikTok).
3. Slip on Battery use.
4. Choose Restricted or Optimized (depending on version) MIUI).
5. Turn off the permission to work in the background (if any).

2. set up automatic battery optimization

MIUI Flexibly manage how the system handles background processes:

1. Open Settings → Battery and Performance → Battery Optimization
2. Select the Applications Selection.
3. For unnecessary programs, set the Restricted mode.
4. For critical (messaging, banks) choose No restrictions.

Use of charge saving mode

If the battery is running out too quickly, turn on the enhanced optimization:

1. Go to Settings → Battery and Performance → Battery Mode.
2. Choose Charge Saving or Supercharge Saving.
3. In this mode, the background activity of most applications will be suspended.

4. Manual stop of background processes

For emergency situations (for example, if the phone is slowing down):

1. Open Settings → Applications → Task Manager.
2. Click Clean – this will close all background processes.
3. Keep in mind that after that, some notifications may come with a delay.

⚠️ Note: On some Xiaomi models (e.g, POCO F5 or Redmi K50) After manually cleaning the background processes, the system can automatically restart critical services (such as Mi Cloud or Google Play Services.

For advanced users, there is another way – using ADB-commands to disable background activity at the system level. However, this method requires unlocking the bootloader and can lead to unstable operation of the phone, so we do not recommend it without extreme necessity.

💡

If notifications from messengers stopped coming after the background mode was limited, check the synchronization settings in the application itself. For example, in Telegram you need to go to Settings. → Notifications and sounds → Background synchronization and enable it.

What happens if you completely turn off the background mode: pros and cons

Some users decide to radically disable background activity for all but the most essential applications.

For example, if you turn off the background mode for Google Play Services, then:

• ✅ Apps will no longer be updated in the background.
• ✅ Reduced battery consumption by 5-10%.
• ❌ Some Google features, such as device search or automatic contact sync, will stop working.
• ❌ Some apps (such as Gmail) won’t receive push notifications.

Therefore, completely disabling the background mode is not suitable for everyone. The best option is to leave without restrictions only critical applications (messengers, banks, navigator) and limit the rest.

Hidden settings MIUI background control

In addition to the standard tools, the MIUI There are hidden features that allow you to more flexibly manage the background:

1. Developer Mode and Process Limitation

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

1. Go to Settings → About Phone → MIUI version and tap 7 times on this item.
2. Back to Settings → Additionally. → For developers.
3. Find options: Limit background processes – set the maximum 2-3 Do not save actions – disables caching activity (saves memory, but applications will run longer).

2. Set up Auto-Run Applications

Many programs run automatically when you turn on your phone or connect to the Internet, to fix this:

1. Open Settings → Applications → Application Management.
2. Select an application (such as AliExpress).
3. Slip on AutoRun and turn it off.

3. Disabling hidden activity through ADB

For experienced users: with the help of ADB You can completely block background activity for specific applications. For example, to turn off Facebook background work, do:

adb shell cmd appops set com.facebook.katana RUN_ANY_IN_BACKGROUND deny

After this command, Facebook will not be able to update the feed in the background, but notifications of messages will still come (if allowed in the app settings).

⚠️ Attention: Use ADB-commands can lead to unstable operation of applications or even systems. Before experiments, back up data through Settings → Additionally. → Backup and reset.

4. setting up the "White List" in MIUI

MIUI automatically adds some applications to the whitelist, allowing them to work without restrictions:

1. Go to Settings → Battery and Performance → Battery Consumption Management by Apps.
2. Select the Applications Selection.
3. In the section Without restrictions, remove unnecessary programs (such as games or social networks).

On some firmware (e.g, MIUI Global for the European market, these settings may be called differently or in other sections. If you do not find the right item, try searching in the settings (the magnifying glass icon in the upper right corner).

💡

The most effective way to save battery is to combine limiting the background for unnecessary applications and adding critical programs (messengers, banks) to the whitelist, balancing performance and battery life.
