Background connections in Xiaomi: why they are needed and how to control them

Introduction: Why Background Connections Are Important for Xiaomi

If you’ve ever noticed that your Xiaomi smartphone is running out faster than you expected, or some apps are being updated without you, it could be the back-end connection, which is integrated into the MIUI operating system, allowing apps and services to communicate with the Internet even when they’re rolled up or inactive. On the one hand, it provides instant notifications, data synchronization and content relevance, and on the other, it can cause increased battery consumption and traffic.

Unlike Android in its pure form, where background management is often hidden in the depths of settings, Xiaomi offers more flexible and visible control tools. However, not all users know how to use them correctly. In this article, we will discuss what background connections are in practice, what tasks they solve, and most importantly, how to configure them so that the smartphone works steadily without wasting resources.

What are background connections and how do they work in MIUI

Background connections are a mechanism that allows Xiaomi applications and system services to communicate with servers even when you are not interacting with them directly, such as messengers (WhatsApp, Telegram) check new messages, email clients sync emails, and weather widgets update forecasts, all this happening behind the scenes, without you.

In MIUI, background connections are implemented on two levels:

• 🔄 System layer: Xiaomi services (e.g. Mi Cloud, Security, Game Turbo) automatically update data to ensure that the device works correctly.
• 📱 Application layer: Each installed application can request permission to work in the background to send notifications or sync content.

It is important to understand that background connections are not equal to background processes, the latter are any tasks performed by an application in a curled state (for example, playing music in Spotify), whereas connections specifically relate to network activity. In MIUI, these mechanisms are closely related, but managed differently.

Why you need background connections: pros and cons

Background connections are a tradeoff between convenience and performance, and let's look at their key advantages and potential drawbacks.

The impact of background connections on Xiaomi’s budget models (e.g. Redmi 9A or Poco M3), where hardware resources are limited, is particularly critical. On flagships (Xiaomi 13 Ultra, Mix Fold 3), the problem is less noticeable due to powerful processors and MIUI optimization.

⚠️ Warning: Disabling background connections for system applications (e.g. com.miui.securitycenter) may cause disruptions MIUI, including account synchronization errors or inability to update the software.

How to Check Which Apps Use Background Connections

To understand which programs are active in the background, use the built-in MIUI tools. Here is a step-by-step instruction:

1. Open Settings → Applications → Application Management.
2. Select the AutoRun tab – here are programs that can run automatically.
3. Go to Traffic Consumption (in the same section) to see which apps are consuming data in the background.
4. For detailed analysis, use the battery. → Battery usage – you can see what processes consume charge even when the screen is off.

Look for apps that are marked "Operating in the background" or "High traffic consumption." Most often, these are:

• 💬 Messengers (Viber, Facebook Messenger)
• 📧 Mail (Gmail, Mi Mail)
• 🎵 Music services (Spotify, Yandex Music)
• 📊 Social networks (Instagram, TikTok)

It is useful for advanced users to use ADB-For example, to see all active connections, run in the terminal:

adb shell dumpsys netstats detail

How to Disable or Limit Background Connections

If you're optimizing your smartphone, there are a number of ways to control background activity, and it's important to be careful not to disrupt critical services.

Method 1: Through the MIUI settings

1. Go to Settings → Applications → Application Management.
2. Select the desired application and open the permissions.
3. Find the "Background Activity" or "Autostart" item and turn it off.
4. For a complete limitation, also disable "Mobile data in the background" and "Wi-Fi in the background".

Method 2: Use of energy saving mode

MIUI has built-in power consumption profiles that automatically limit background activity:

• 🔋 Battery → Energy saving mode – moderate restriction.
• ⚡ Super energy saving is a tight constraint (disables most background processes).

Method 3: Through the Developer (for experienced users)

If standard methods are not enough, you can use ADB:

adb shell cmd appops set <package_name> RUN_ANY_IN_BACKGROUND deny

Replace. <package_name> to the application identifier (e.g. com.whatsapp).

⚠️ Note: Disabling background connections for Google Play Services (com.google.android.gms) may result in Google account sync errors and inability to use certain features (e.g. Google Pay or Find My Device).

💡

Before you massively shut down background connections, check to see if you are using features that depend on them. For example, if you rely on SMS notifications in a banking application, it is best not to limit its background activity.

What applications can be safely restricted

Not all programs are equally important for the background, but here is a list of categories that can be optimized without risking functionality:

Here is what is not recommended to limit:

• 📞 Messengers (if call/message notifications are important)
• 🏦 Banking applications (due to the risk of missing out) SMS or push notifications)
• 🔒 Antivirus and security tools (Mi Security, Google Play Protect)

How background connections affect battery and performance

One of the main consequences of active background connections is increased battery consumption. According to Xiaomi tests, each application running in the background can add from 1% to 5% of charge per day. If there are dozens of such applications, the difference becomes noticeable: a smartphone can discharge 20-30% faster.

The impact on productivity is less obvious, but it is also present:

• 📉 System Slowdown: Constant network requests load the processor and communication module, which can lead to lags.
• 🔥 Overheating: Active data transfer (especially over mobile network) increases the load on the chipset, which leads to heating.
• 📶 Unstable Internet: If too many applications try to access the network at the same time, the connection speed may drop.

Interesting fact: in MIUI 14 and later, Xiaomi has implemented a “Smart Optimization” mechanism that automatically suspends background activity for rarely used applications.

💡

The optimal balance is to leave the background connections only for critical applications (messaging, banking, security) and disable them for everything else, which will save up to 15-20% of battery life per day without losing functionality.

Common Problems and Their Solutions

When working with background connections, Xiaomi users often face typical problems. Let’s consider the most common ones and how to fix them.

Problem 1: Apps don't get notifications after background restriction

Reason: Autostart or background activity for the messenger is disabled.

Decision:

1. Return autorun permission to Settings → Applications → Application Management.
2. Check if the app is added to the list of “Optimized” in the battery settings.
3. For WhatsApp and Telegram, additionally enable “Show notifications” in the app settings.

Problem 2: Battery discharges quickly despite limitations

Reason: Some system services (MiuiDaemon, MiPush) continue to work in the background.

Decision:

• Check the activity through adb shell dumpsys batterystats.
• Turn off unnecessary system notifications in Settings → Notifications → System notifications.
• Update MIUI to the latest version – the new builds optimized the work of background processes.

Problem 3: Mobile traffic is being spent on unknown things

Reason: Background data synchronization (e.g. weather or news updates).

Decision:

1. Go to Settings. → SIM-maps and mobile networks → Traffic consumption.
2. Set a traffic limit and disable Background Data for unnecessary applications.
3. Use Google Datally to monitor your consumption.

⚠️ Note: If Google services (such as YouTube or Maps) stop working after the background connections are turned off for Google Play Services, return the default settings and limit only mobile data in the background, leaving access over Wi-Fi.
