Background connection on Xiaomi Redmi: clarification and configuration

If you own a Xiaomi Redmi smartphone and you notice the “background connection” option in your settings, but you don’t understand what it is, you’re not alone. This term often raises questions among users, especially when it comes to battery consumption or mobile traffic. In this article, we’ll take a closer look at what’s behind this feature, how it affects the device and why it can’t be turned off thoughtlessly.

Background connectivity is a mechanism that allows applications and system services to communicate with servers even when they are not active on the screen. For example, messengers receive new messages, email clients check incoming emails, and weather widgets update forecasts. At Redmi, this feature is integrated into the MIUI system and has its own features that are worth knowing about.

It is important to distinguish background connectivity from normal Internet traffic. The former works unobtrusively to the user, but can significantly affect device autonomy and mobile data consumption. In this article, we will not only explain the term, but also show how to manage this feature to make the smartphone work optimally.

What is a background connection and why it is needed

Background connectivity is the continuous exchange of data between a smartphone and application servers, which occurs in a hidden mode, without which many functions of modern smartphones will simply cease to work.

• 📱 Notifications in messengers (WhatsApp, Telegram, Viber) come instantly, even if the application is closed.
• 📧 Mail updates automatically and you see new emails without manual check.
• 🌦️ Weather widgets show current forecast without requiring the application to be opened.
• 🔄 Synchronize contacts, photos and notes with cloud services (Google Drive, Mi Cloud).

On Xiaomi Redmi, background connectivity is implemented through a combination of system services and Android APIs. MIUI adds its optimization algorithms that try to balance performance and power consumption. For example, if the smartphone is long gone, the system can suspend background activity of some applications to save charge.

But not all apps are equally important: Facebook or Instagram, for example, can aggressively use the background connection to display ads or collect analytics, resulting in unnecessary battery consumption, and this raises the question: how to turn off the unnecessary while retaining critical features?

How background connectivity affects battery and traffic

The main disadvantage of the background connection is the increased power consumption. Every application that periodically “wakes up” to update the data makes the processor and communication module work longer, as a result, the battery goes down faster, especially if there are many such applications.

The second is mobile traffic consumption, where some apps (like TikTok or YouTube) can upload content in the background to speed up the display when you open it, which causes even with minimal usage, the smartphone to eat gigabytes of traffic. At Redmi, this problem is partly solved by Background Limitation, but it doesn't always work perfectly.

Xiaomi Redmi with MIUI 12 and later has a built-in monitoring tool called Battery → Battery Use. Here you can see which apps are most energy-consuming in the background. If you notice that an app is using more than 10-15% of its charge per day, you hardly use it, that's a reason to check its settings.

⚠️ Warning: Disabling the background connection for system applications (such as Mi Security or Google Play Services) can cause the smartphone to function unstable, including notification and sync issues.

Where to find background connection settings on Xiaomi Redmi

Background connection on Redmi is managed through several menus. The main settings are in:

1. Settings → Applications → Application Management → [Select App] → Battery
2. Settings → Battery and Performance → Application Battery Management
3. Settings → SIM-maps and mobile networks → Transfer of data → Background data

Let’s look at each item in more detail:

• 🔋 Application Battery Management – you can choose one of three states for each application: No restrictions – background activity is not limited (suitable for instant messengers); Limit background activity – the application will not update data in the background. Deep Optimization – the application will be suspended if it is not used for a long time.
• 📶 Background data – allows you to completely disable background traffic for individual applications or for all at once (via Limit background data).

The Redmi Note 10/11/12 and other MIUI 13/14 models also feature Intelligent Power Distribution, which automatically optimizes background activity based on the level of charge, for example, with 20% of the battery, the system begins to aggressively restrict background processes.

What applications can be safely restricted

Not all apps are equally useful in the background. Některé z nich můžete bezpečně omezit, aniž by to ovlivnilo vaše každodenní použití. Zde je seznam kategorií, které lze upravit:

• 🎮 Games – most games do not need background activity, except for online multiplayers (PUBG Mobile, Free Fire).
• 📺 Streaming services – YouTube, Netflix, Twitch only upload data when opened.
• 🛒 Shops and promotional apps – AliExpress, Wildberries, Ozon frequently update discount notices.
• 📊 Analytics and Trackers – Google Analytics, Firebase collect data for developers, but not for the user.

On the other hand, it is not recommended to limit:

• 💬 Messengers (WhatsApp, Telegram, Viber) – otherwise you will receive messages with a delay.
• 📧 Email clients (Gmail, Mi Mail) – new emails will not automatically arrive.
• 🔒 Two-factor authentication applications (Google Authenticator, Microsoft Authenticator).

On Redmi models with Snapdragon 8-series processors (such as the Redmi K50), background optimization works better thanks to Qualcomm Quick Charge AI technology, which analyzes application activity and reduces the power consumption of non-critical processes.

⚠️ If you are using Xiaomi Redmi with two SIM-Disabling background data for one of them can lead to the fact that notifications will only come to the main card. SIM. Check the settings in SIM-maps and mobile networks → Transfer of data.

How to completely disable the background connection (and whether it is worth it)

Completely disconnecting the background connection is possible, but it is highly discouraged.

• ❌ Notifications will only come when you manually open applications.
• ❌ Synchronization of contacts, photos and files will stop.
• ❌ Some system features (like Find My Device) will stop working.

If you want to try it, do it selectively:

1. Go to Settings. → SIM-maps and mobile networks → Transfer of data.
2. Select to Limit Background Data.
3. In the list of applications, mark those for which you want to block background traffic.

For a radical shutdown of all background processes, you can use the energy saving mode:

1. Open Settings → Battery and Performance.
2. Select Power Saving Mode or Over-Energy Saving.
3. Activate it – it will suspend most of the background activity.

The Redmi Note 12 Pro+ and other flagships have an option called Deep Optimization, which further limits background processes but can cause delays in some features.

💡

If notifications stop coming after disconnecting the background connection, check the sync settings in your Google account: Settings → Accounts → Google → Account Sync.

Frequent problems and their solutions

Xiaomi Redmi users often face the following problems related to background connectivity:

If the problem has not disappeared after the changes in the settings, try:

1. Reboot the smartphone.
2. Clear the app cache (Settings → Apps → [Application] → Clear the cache).
3. Update MIUI to the latest version.

⚠️ Note: Some Redmi models (e.g. Redmi) 9A Redmi 8 after upgrading to MIUI 12.5 may be disrupted by the background services, in which case resetting the network settings: → SIM-maps and mobile networks → Resetting network settings.

Tips for optimizing background connection

To make the background connection work efficiently without consuming excess battery and traffic, follow these recommendations:

• 🔄 Regularly check the activity of applications in Settings → Battery: Remove or limit those that consume too much resources.
• 📵 Use the “Do Not Disturb” mode at night to suspend background activity while sleeping.
• 🔋 Activate the adaptive battery (Settings) → Battery → Adaptive battery, so that MIUI Automatically optimized background processes.
• 📶 Limit background data to your mobile network if you are frequently connected to Wi-Fi. This will reduce traffic consumption.

For advanced users, there is another way to control — ADB-They can manually set restrictions for specific applications, for example, to turn off background activity for Facebook, perform:

adb shell dumpsys deviceidle whitelist -com.facebook.katana

But beware: improper use of ADB can lead to unstable operation of the system. If you are not sure about your actions, you should use the standard MIUI settings.

💡

The optimal balance is when the background connection is allowed for mission-critical applications (messaging, mail) and limited to others. Regular activity checks will help to extend battery life without compromising functionality.
