How to disable background mode on Redmi 8

Redmi smartphones have long established themselves as reliable devices with decent battery life, but over time, even the most powerful battery begins to discharge faster than usual. Redmi 8 users often encounter a situation where the phone gets hot in their pocket and the charge melts before their eyes without actively using the screen. The culprit is usually apps running in the background that continue to consume CPU and network resources even after you've minimized them.

Turning off background activity is not just a way to extend battery life into the evening, but also a method of improving overall system performance. The MIUI shell installed on your device provides powerful tools for controlling startup and services, but they are often hidden from the eyes of the average user or configured incorrectly by default. In this article, we will look in detail at how to limit unnecessary processes so that your Xiaomi Redmi 8 works stably and quickly.

Before taking radical measures, you need to understand the difference between system services and third-party software. Completely stopping all background processes may result in you stopping receiving notifications from instant messengers or missing an important call. Therefore, the approach must be balanced: we will disable only those applications that are really not needed in the background, while maintaining the functionality of key services.

Analysis of energy consumption and identifying the culprits

The first step towards optimization is diagnostics. The Android system collects detailed statistics about which apps are using up battery power, even when the screen is off. This information is hidden deep in the settings, but it is critical for making the right decisions. Without understanding who exactly is “eating” your battery, any action to disable background modes will be shooting blindly.

To access this data, you need to go to the Settings → Battery and performancesection. Here you will see a discharge graph and a list of applications, sorted by the degree of impact on autonomy. Pay attention to apps that are at the top of the list but that you rarely use during the day. Often these are social networks, news aggregators or games that continue to synchronize data or show ads in the background.

In some cases, you may find a system process called Media Server or Google Play Services, occupying a disproportionate amount of resources. This may indicate a synchronization error or a stuck download process. If such an application is not critical to the operation of the phone, forcing it to stop through the app menu can temporarily solve the problem of overheating and rapid drainage.

⚠️ Attention: If you see that an unknown application is consuming more than 20% of power in the background, this may indicate the presence of malware. It is recommended to scan the device with the built-in antivirus or remove a suspicious app.

It is also worth considering that the MIUI interface may differ slightly depending on the firmware version installed on your Redmi 8. Developers periodically change the location of menu items, adding new energy-saving functions. If you do not find the item where it is described, use the settings search by entering the keyword “battery” or “applications.”

Setting background activity restrictions for specific applications

The most effective way to combat parasitic resource consumption is to individually configure each application. Android allows you to manually set behavior rules for apps, prohibiting them from starting on their own or running when the screen is off. This gives the user complete control over what happens inside the operating system.

To begin, open the list of all installed apps through Settings → Applications → All applications. Select the app you want to restrict from the list, such as a popular social network or game. Inside the application menu, find the item Battery saver (or “Activity Control”). Here you will be offered several behavior options: “No restrictions”, “Battery saver” and “Hard limit”.

Selecting the “Hard limit” mode completely prohibits the application from running in the background. You can only open it manually by clicking on the icon, but as soon as you minimize the app, all its processes will be stopped. This is ideal for games, video players or photo editors that don't need a constant network connection. However, this mode is absolutely not suitable for instant messengers, since you will stop receiving messages until the chat is opened.

• 📱 The “Unlimited” mode is suitable for instant messengers, email clients and alarm clocks that need constant communication.
• 🔋 The “Battery Saver” mode allows the application to run in the background, but limits its activity when the screen is turned off.
• 🚫 The “Hard Restriction” mode completely kills background processes immediately after minimizing the application.

It is also worth checking the permissions in this menu. Often applications will request access to geolocation or microphone and continue to use them in the background to collect data. Disabling unnecessary permissions in combination with limiting background activity gives a double saving effect.

Managing startup and background processes in MIUI

The MIUI shell has a unique feature - aggressive memory management, which, however, by default allows many applications to run along with the system. This is called autorun. If you have several dozen apps installed on your Redmi 8, then when you turn on the phone they all try to start at the same time, creating a huge load on the processor in the first minutes of operation. To disable this function, go to the application, which is pre-installed on all Xiaomi devices. At the bottom of the screen or in the settings menu (gear icon), find

To disable this feature, go to the application Security, which comes pre-installed on all Xiaomi devices. At the bottom of the screen or in the settings menu (gear icon), find the item Permissions, and then select Autorun. You will see a list of all applications that are allowed to start automatically. Feel free to disable the toggle switches next to all apps except the most necessary ones, such as phone, messages or antivirus.

In addition to autorun, MIUI has the “Floating Windows” function and related background services. Some applications, even when closed, may leave their services active to support floating window or fast loading features. In the same menu Permissions find the item Other permissions and check if there are active items related to displaying on top of other windows or running in the background.

⚠️ Attention: Disabling autorun for Google system services or Xiaomi services may result in incorrect synchronization of contacts, calendar, and device search. Be careful with system components.

Another important aspect is running in the background for applications that use Bluetooth or Wi-Fi. Some smart home utilities or fitness trackers need to be running all the time. If you disable the background mode for them, they will stop transmitting data. Always analyze the purpose of the app before applying strict restrictions.

Using Developer Mode to control processes

For advanced users who want maximum control over the system, there are hidden settings available through Developer Mode. This menu section allows you to manage background process limits on a global level, without going into the settings of each individual app. However, you need to use these tools with extreme caution, as incorrect settings can lead to unstable operation of the phone.

To activate developer mode, go to Settings → About phone and quickly click on the item MIUI version about 7-10 times until a notification appears indicating that you have become a developer. After this, a new section will appear in the main settings Advanced → For developers. Scroll down the list to the “Applications” block.

Here you will be interested in the item Background process limit. By default, the value is “Standard Limit”, which is determined dynamically by the system. You can change it to "No background processes" or set a specific number (for example, "No more than 1 process"). This will force the system to immediately terminate any applications as soon as you switch to another.

Setting value	Description of system behavior	Recommended use
Standard limit	The system decides when to close applications based on available memory.	Default mode, suitable for most users.
No background processes	No application remains in memory after minimizing.	Only for extreme battery saving, notifications may not arrive.
No more than 1 process	Only the application that you are using right now remains in memory.	For old devices with a small amount of RAM.
No more than 2 processes	Allows you to keep the current and one previous application in memory.	Balance between switching speed and saving resources.

Using these settings on Redmi 8 can significantly speed up work interface, since the RAM will be constantly cleared. However, be prepared for the fact that when you return to the application, it will be downloaded again rather than restored from memory, which may take extra seconds.

Risk of using developer mode

Changing the limit of background processes can disrupt the work of widgets on the home screen and stop real-time data synchronization, for example, updating currency rates or weather.

Optimization through the built-in "Security" application

You should not ignore the built-in optimization tools provided by the manufacturer. The application Security on Redmi 8 is not just an antivirus, it is a whole harvester for managing device resources. Regular use of its features helps keep your system clean and prevents background tasks from piling up.

Launch the application and click on the big green button to check the security. In addition to scanning for viruses, the system will offer to clear the cache and close applications running in the background. But more important is the “Memory Boost” (or “RAM Cleaner”) function, which forcefully terminates processes. You can set this application to automatically close background tasks when the screen is locked.

In the Security application settings, find the section Battery. Here you can enable the “Close apps when the screen is locked” feature. This is a very useful option for those who want to be sure that the phone does not do anything unnecessary when it is in their pocket. You can add important apps to Exceptions so that they continue to run even when the feature is turned on.

• 🧹 Regularly clearing the cache prevents the accumulation of temporary files that can slow down background services.
• 🔒 The feature of blocking applications in the background is useful if you know that the next few hours the phone will not be used.
• ⚙️ Setting exceptions is critical so as not to miss a call or message from loved ones.

Also in the “Security” application there is a “Power” section where you can select the battery mode. Switching to the "Economy" mode automatically limits background synchronization, reduces brightness and turns off vibration, which comprehensively solves the problem of fast discharge.

⚠️ Attention: The interface and capabilities of the Security application may be updated along with the MIUI version. If you do not see the functions described, check for updates for system applications in the GetApps store.

Frequent errors and additional tips for saving

Even after performing all the above steps, some users continue to complain about rapid discharge. Often the problem lies not in the settings, but in usage habits or external factors. For example, a weak cellular signal forces the phone's modem to work at maximum power, constantly searching the network, which drains the battery faster than any background applications.

Another common mistake is the use of “live wallpapers” and heavy widgets. They are constantly updated and use the GPU in the background. Replacing dynamic wallpaper with a static picture can give a significant increase in autonomy. It is also worth checking whether geolocation (GPS) is always turned on for all applications at once.

If you use the function Always On Display (always on screen with clock), keep in mind that on AMOLED screens it is economical, but still consumes energy. Disabling this feature or setting it to run only on a schedule will help conserve battery. Don't forget that Redmi 8 has an IPS screen in some modifications, where any active pixels consume energy evenly.

In conclusion, remember that the ideal settings does not exist. You will have to use trial and error to find a balance between functionality and economy. Start by disabling autorun for games and social networks, then set up strict restrictions for rarely used apps, and only as a last resort, resort to settings for developers.

FAQ: Frequently asked questions

Why did notifications from WhatsApp stop coming after disabling background modes?

This is normal behavior when selecting the “Hard Limit” mode. Messengers require a constant connection to the server to receive push notifications. To fix this, go to the WhatsApp app settings, select Battery Saver and set it to Unlimited. Also make sure that there is a checkmark for it in autorun.

Is it safe to set the “No background processes” limit in the developer settings?

This is safe for the phone’s hardware, but inconvenient to use. The system will constantly reload applications, which can lead to the loss of unsaved data (for example, a draft message) and increased bandwidth consumption when re-downloading content. Use this mode only temporarily when you need to save as much power as possible.

How to disable the background operation of Google Play Services to save battery?

It is not recommended to completely disable Google Play Services, as this will disrupt the operation of the application store, maps, and account synchronization. However, you can go to Settings → Applications → All applications → Google Play Services → Battery Saver and select the "Economy" mode to limit their activity in the background without completely turning them off.

Does turning off background data affect the Internet? in the browser?

No, disabling background data prevents applications from using the Internet when they are minimized. When you open a browser or any other application, network access is restored in full. This is useful for blocking ads and trackers in the background.
