Xiaomi App Activity Control: A Complete Guide to Optimization

Owners of Xiaomi smartphones and tablets often face a mysterious notification or section in the settings called “Application Activity Control.” Many users, wanting to extend the battery life of their device, blindly turn off all background processes, leading to broken messengers, lack of notifications and malfunctions in the smart home. Understanding how exactly the MIUI or HyperOS operating system manages resources is critical for the proper operation of the gadget.

This article will help you understand the intricacies of managing background tasks without compromising functionality, and we will look at which processes can be safely stopped and which require constant operation, and how to set the system so that it works exactly as you want it to work, rather than as the energy saving algorithm decided.

What is Application Activity Monitoring in MIUI System

Application activity control is a system mechanism that monitors running programs and limits their access to CPU time and the Internet when you are not using them. Unlike pure Android, the MIUI shell is known for its aggressive approach to energy saving, often completing processes immediately after turning off the screen, this is done to ensure that the smartphone battery is spent as economically as possible.

But this kind of zeal often causes important notifications to arrive late or not at all, such as messages from corporate email clients or fitness trackers that may not sync in the background, and understanding autonomous startup and battery limitations is key to addressing these issues.

The system divides applications into several categories by trust: some programs are free to run, others are limited only when connected to Wi-Fi, and others are completely frozen, and the user can manually adjust these rules, creating exceptions for the most important services.

Why limit background processes and when it is necessary

The main purpose of limiting background processes is to save battery power and free up RAM. If you run a lot of heavy applications, such as navigators, social networks and games, they continue to consume resources even in a curled state.

There are scenarios where tight control is necessary, for example, if you leave your phone in navigator mode or turn on the sound recording, but the screen goes out, the system can kill the application to save energy, in such cases you need to force the background activity to be allowed, and this is also true for older smartphone models, where the amount of RAM is limited.

⚠️ Warning: Completely disabling background activity for Google or Xiaomi system services may cause Play Market Store to fail, contact syncs, and cloud services to work.

It's important to distinguish between apps that you really need all the time and apps that are just hanging in your memory. Social media, news aggregators, and games don't require constant background work unless you've run them yourself. They can be safely limited.

Where to find application management settings

There are several ways to get to the management settings, as the menu layout can vary depending on the version of MIUI. Most often the path is as follows: go to Settings → Applications → Application Management. Here is the full list of installed software.

An alternative and faster way is to use the built-in Security app, which has a Battery or Energy Saving section where you can customize the behavior of groups of applications, and there is a hidden developer menu, but it is usually not required for basic configuration.

For detailed configuration of a specific application:

• 📱 Open Settings and find the Application section.
• 🔍 Select the desired application from the list or find it through search.
• ⚙️ Click on Advanced Settings or Battery.
• 🔋 Select mode: No restrictions, limit background activity or complete restriction.

In some firmware versions, these settings are duplicated in the Notifications and Status Bar menu, where you can more flexibly configure which notifications will arrive and which will be blocked by the system.

Set up auto-start and battery limitations

One of the most important features is autorun control, and if an application has autorun permission, it can start immediately after the phone is turned on or after another application's page is updated, which is often used by instant messengers to deliver messages, but also used by advertising modules.

To manage this, go to the Security app → Permissions → Auto Run. Here you will see a list of all programs that are trying to run themselves, and it is recommended that you leave only messengers (Telegram, WhatsApp) and system services on.

The second important parameter is "Restricted Background Activity," and if you select "No Limits" mode, the app will work in the background completely, ignoring the energy saving modes, which is useful for activity trackers, smartwatches, and email clients.

You don't want to give full rights to all apps in a row. If you allow "no limits" for a dozen games and utilities, the battery will run out much faster, and the phone can start to heat up even in your pocket.

Differences in energy saving regimes

Xiaomi offers several levels of energy saving, each of which has a different effect on the activity of applications, and understanding the difference between them will help avoid confusion when the phone suddenly stops performing the desired tasks.

Normal mode allows applications to function as standard. Energy Saving mode limits background synchronization and reduces screen brightness. Ultra-saving (or Super-saving) mode turns a smartphone into a simple caller, leaving only basic functions and selected contacts active.

When you go into saving mode, the system can force you to close applications you've recently used, which is normal behavior to keep the remaining charge in a critical situation.

Solving Notifications and Work Problems in the Background

If you notice that messages have stopped coming or music stops when the screen is turned off, you may be responsible for the activity control settings, and first check if the app is on the list of “sleeping” or restricted.

Often, simply restarting an application or cleaning its cache helps, but if the problem recurs, you need to fix the application in RAM. To do this, open the menu of running applications (a swipe from the bottom up or a menu button), find the right window and pull it down (or press the lock) to appear the lock icon, which will prevent the system from unloading the application from memory.

It's also worth checking the notification settings inside the app itself, sometimes locking is not in the system, but in the account settings, make sure push notifications are enabled and work in the background is allowed.

⚠️ Note: When you clean the memory through the “Junk” or “Clean All” button in the Task Manager, applications that are not fixed in memory (without a lock) will be forcibly closed, even if they have background permissions.

For mission-critical applications such as alarms or remote monitoring, it is best to set the No Limits mode and fix them in memory, ensuring that no task is missed.

💡

Useful tip: If you’re using a smartwatch or Mi Band bracelet, be sure to add the Mi Fitness (or Zepp Life) app to battery and autostart exceptions, otherwise the steps won’t sync and notifications will come with a delay.

Frequently Asked Questions (FAQ)

💡

Competent setting of activity control allows you to extend the life of the battery by 15-20% without losing important notifications, if you correctly configure exceptions for key applications.
