Background connection on Xiaomi: why you need, how to disable and what applications use it

Have you ever noticed how some Xiaomi apps keep updating data even when you don't open it? For example, messengers show new messages instantly, the weather updates without you, and social networks load the feed in advance. All of this is due to the background connection, the mechanism that allows programs to interact with the Internet in a hidden mode. But how exactly does it work on Xiaomi devices, why should it be limited sometimes, and how to do it without harming functionality? Let's get to the bottom line.

Xiaomi smartphones (especially those based on MIUI or HyperOS) are known for aggressive optimization of background processes. On the one hand, it saves battery power and traffic, on the other hand, it can interfere with important notifications or synchronization. In this article, we will explain in detail what background connection is, which applications use it most actively, and how to adjust the balance between performance and convenience.

What is a background connection and why it is needed

Background connectivity is the ability of an app to communicate with servers over the Internet, even when it is folded or not active on the screen. Without this mechanism, many functions of modern smartphones simply would not work:

• 📩 Messengers (WhatsApp, Telegram, Viber) would not receive messages in real time.
• 🌦️ Weather widgets would stop updating data automatically.
• 🎵 Music services (Spotify, Yandex Music) could not cache tracks for offline listening.
• 📈 Social networks (Instagram, TikTok) would not download content in advance, which would make the tape load longer.

On Xiaomi, background connectivity is implemented through a combination of system services and power saving settings. Unlike pure Android, where background processes are controlled by standard tools, MIUI/HyperOS adds its optimization layer, which means that even if you allow an application to run in the background at the Android level, the system can block its activity to save resources.

It is important to understand: background connection ≠ The first is responsible for communicating data over the network, the second is responsible for performing any tasks in a curled state (for example, playing music or recording a track in Mi Fitness.

How background connectivity affects battery and traffic

The main disadvantage of background activity is increased battery consumption and mobile traffic. According to Xiaomi tests, up to 30% of the power consumption in standby mode can be due to background processes, especially on budget models (Redmi Note 12, POCO M6), where batteries are smaller in capacity.

Here’s how the backup connection affects resources:

Since upgrading to HyperOS, the app’s background activity has become more aggressive: the system now blocks processes more often if the smartphone isn’t charging, a move that is due to a new energy-saving policy Xiaomi has implemented to increase battery life.

⚠️ Note: If you notice that notifications from messengers stopped coming after the HyperOS update, check the Battery Optimization settings for these applications.

What applications most often use background connection

Not all programs are equally active in the background, here are the top apps that use background connectivity most intensely on Xiaomi:

• 💬 Messengers: WhatsApp, Telegram, Viber, Signal. Without a background connection, you will not receive messages in real time.
• 📱 Social media: Instagram, TikTok, Facebook. Upload content in advance, even when the app is closed.
• 🎧 Music services: Spotify, Yandex Music, Apple Music. caching tracks and updating playlists.
• 📊 Fitness trackers: Mi Fitness, Google Fit, Strava. synchronize data with wearable devices.
• 📰 News aggregators: Yandex Zen, Google News. Updating the feed in the background.
• 📍 Maps and navigation: Google Maps, Yandex Maps, 2GIS. Tracking location for traffic notifications.

Xiaomi has a built-in tool for monitoring background activity: go to Settings → Applications → Application Management → Three dots (menu) → Background activity. Here you will see a list of programs sorted by resource consumption in the background.

💡

If you don’t use an app every day (like AliExpress or Wildberries), limit its background activity, saving up to 10% of your charge per week.

How to Disable Background Connection for Individual Applications

If you want to save battery power or traffic, you can limit the background connection to unnecessary apps.

1. Open Settings and go to the Application section.
2. Select Application Management and find the desired application in the list.
3. Slip it, then select Data Transfer (or Mobile Traffic on some models).
4. Turn off the Background Data Transfer option (may be called Background Connection or Background Traffic).
5. For a complete restriction, also turn off AutoRun in the same menu.

For MIUI 14 and HyperOS, the path may be slightly different.

Settings → Applications → Battery Management → Select the Application → Background Limitations

If the Background option is not available, then the application uses system services (for example, Google Play Services), in which case it can only be limited through Settings → Google → Google Account → Data Sync.

⚠️ Note: Disabling the background connection for instant messengers will cause notifications to be delayed, for example, WhatsApp will only show new messages after manually opening the application.

The difference between MIUI and HyperOS: what has changed in the background

With the release of HyperOS (replacing MIUI on the new Xiaomi 14, Redmi K70 models), the logic of the background processes has changed dramatically.

If you have lost notifications or apps don’t sync after upgrading to HyperOS, do the following:

1. Add the problem app to No Limits in Settings → Battery → Battery Mode.
2. Turn off Adaptive Battery Optimization in the same menu (this will increase charge consumption, but return stability).
3. Restart your smartphone – sometimes changes are only applied after a reboot.

What to do if the backup connection is not working

Sometimes users have the opposite problem: the background connection doesn't work and the apps stop updating the data. Here are the typical reasons and solutions:

• 🔋 Aggressive battery optimization: HyperOS can completely block background processes to save charge.Solution: Add the app to exceptions in Settings → Battery → Battery mode.
• 📵 Mobile traffic restrictions: Some operators (e.g. Tele2 or Iota) block background traffic at the network level. APN or contact support.
• 🔄 Sync failure: If a problem with Google services (e.g. Gmail or Google Photos is not updated), go to Settings → Google → Google account and enable manual synchronization.
• 🛠️ Firmware errors: On some models (Redmi Note 11, POCO X5) After the update, the background settings are lost. Solution: reset the network settings in Settings → SIM-maps and mobile networks → Resetting network settings.

If nothing helps, try resetting the app settings:

Settings → Applications → Application Management → Select Problem → Storage → Data Reset

On HyperOS devices, you may need additional permissions to work in the background after resetting your application settings. Remember to reset autorun and background activity.

💡

Before resetting the app settings, back up its data (such as WhatsApp chats or Chrome bookmarks) as they will be deleted.

Tips for optimizing background activity on Xiaomi

To balance battery savings and convenience, follow these guidelines:

1. Separate applications into groups: 🔹 Critical: messengers, mail, banking applications - leave without restrictions. 🔹 Moderate: Social Media, Music – Limit background traffic, but leave auto-run. 🔹 Unnecessary: games, rarely used services - turn off the background completely.

Use Adaptive Battery Mode: HyperOS has an Adaptive Mode (Settings → Battery) option that automatically adjusts background activity depending on the level of charge.

Set time limits: In Settings → Applications → Battery management, you can set a schedule when background processes will be limited (for example, at night).

Control mobile traffic: In Settings → SIM-maps and mobile networks → Set a limit on background traffic for individual applications.

For advanced users, there is a way to fine-tune through ADB (Android Debug Bridge) for example, to completely disable optimization for a particular application, follow the command:

adb shell dumpsys deviceidle whitelist +com.example.app

Where com.example.app is the batch name of the application (you can find out through the App Inspector in Google Play).

⚠️ Attention: Use ADB requires the inclusion of debugging USB In Settings → The phone. → Version. MIUI (7 times tap the version, then return to the Additional settings → For developers: Incorrect commands can disrupt the system.
