Modern smartphones in the Redmi and Poco series are equipped with powerful processors and a large amount of RAM, but even this does not always save from rapid battery discharge. The main reason is often applications that continue to work in the background, consuming system resources and Internet traffic without the user’s knowledge. Understanding how to turn off the background mode on Xiomi Android is a key skill for prolonging the autonomy of the device.
MIUI has its own process control features that differ from standard Android. Aggressive battery optimization can help or interfere: sometimes the system kills the right messengers too early, and sometimes allows unnecessary programs to hang in memory for hours.
In this article, we’ll take a look at all the available methods to limit background activity, learn how to prevent specific applications from running automatically, how to use hidden developer settings, and what Xiaomi system features will help control power consumption. This guide is relevant for most models, including the Redmi Note and the budget C series.
Managing Auto Start Through Security Settings
The first step to optimizing the system is to control the programs that start with the phone, and many users are unaware that the installed games or photo editing utilities are trying to start their services immediately after the operating system is loaded, putting an extra strain on the processor at the most critical moment.
There's a separate tool in the MIUI shell to control this, which allows you to see the full list of programs that have permission to start, and turning off unnecessary positions here is the most effective way to prevent the accumulation of junk processes in RAM during the day.
To get to the menu, open the Security app, which is pre-installed on all of the brand's smartphones. In the tool list, look for AutoStart. Here you'll see the switches opposite each app. Leave only those programs that are critical to you from the moment you turn on the phone, such as messengers or alarms, on.
- 🚀 Disabling auto-run heavy games significantly speeds up the inclusion of the smartphone.
- 🔋 Reducing the number of active processes directly affects battery life.
- ⚙️ System services are better not to touch if you are not sure of their purpose.
⚠️ Warning: Do not disable auto-start for system components MIUI, Google Play or antivirus software, otherwise the phone may not work properly or may stop receiving important updates. After making changes to the autorun list, it is recommended to restart the device, which will allow the system to re-allocate resources, given the new restrictions. You will notice that the smartphone has become more responsive, and the amount of free RAM in the simple has increased. 📊 What's your model? Xiaomi/Redmi?Redmi Note 10Redmi Note 11Poco X3Poco F3Another model is Background activity restriction for specific applications If certain programs continue to consume a charge even after the autorun is banned, tougher measures must be applied. This allows you to fine-tune the system without affecting the rest of the components. Go to Settings and select the Apps section, then click All Apps. Find a glutton program like a social network or news aggregator in the list. Inside the app menu, find Battery or Energy. Here you will be offered several options for system behavior. Choose an option without restrictions if you need instant notifications, or Limit background activity to save energy. The latter option means that the application will only work when you open it, and all background processes will be frozen. This is the ideal option for rarely used programs. ☑️ Checking the settings of the application Find the application in the list Open the Battery section Select Limit activity Check the notifications: 0 / 4 You should also pay attention to the Other Permits inside the app menu, where you can deny the program access to geolocation or microphone when it's not in use, and this is another layer of protection for your privacy and battery. MIUI Shell MIUI It offers built-in power profiles that automatically adjust background activity, and it's a ready-made solution for those who don't want to manually configure each application, and switching between modes is fast and has tangible results. In the Battery menu you will find three main modes: Balance, Economy and Ultra. In Economy mode, the system forcibly restricts the background activity of most applications, reduces the brightness of the screen and turns off data synchronization. This is useful when there is no charger at hand. Ultra mode turns the smartphone into a regular “bell ringer”. In this state, only calls, messages and alarms are available. All other applications, including Internet browsers and social networks, are completely blocked. Launching any other application will require you to leave this mode. Processes Notifications Recommended use Balance Standard All Daily use Economy Limited Only Important Low battery charge Ultra Full lock Only calls/SMS Critical discharge ⚠️ Note: When power saving mode is enabled, messengers may stop sending messages until the screen is unlocked. Keep this in mind if you're waiting for an important call via WhatsApp or Telegram. MIUI There's a hidden battery test menu. To get there, open the Phone app and dial ##6485##. You can see the detailed flow statistics here, but you can't change the parameters without understanding. For those who want to gain full control of the system, there are hidden developer settings, where you can force the process that the system normally considers important to you. Incorrect configuration can cause the interface to crash. To activate this section, go to About Phone and quickly click on the version seven times. MIUI. After the message “You became a developer” appears, go back to the main settings menu and find the option -> For developers, in the list of options, find the Applications section, and here you will be interested in the option "Background Process Limit"; the default is "Standard Limit", but you can choose "No More than 1 Process" or "No Background Processes". This will force the system to aggressively unload applications from memory immediately after folding. ⚡ Setting a limit of 1 process significantly speeds up work on older devices. 📉 Apps will be downloaded again every time they open, consuming more traffic. 🛑 Multitasking in this mode almost ceases to function. Also on this menu you can find the item "Inactive applications." By enabling this feature, you will prevent the system from running applications that you have not used in a long time. This is a great way to keep the system clean without constant manual intervention. 💡Before you change the developer's settings, write down or take a picture of the original settings, which will help you quickly get things back to normal if the phone starts to behave strangely. Many users are used to constantly "kill" applications through the menu of open windows. MIUI (The system itself effectively manages the memory allocation, and a forced shutdown causes the processor to waste energy on restarting, however, if a particular application is “hang-up” or is not behaving correctly, manual cleaning is necessary. The swipe up the app card in the recent task menu will close it. the Clear button (cross or broom) will close all background programs at once. Task Manager also allows you to block important applications from closing, by pressing the app card and pressing the lock icon, which will not be deleted when you press the clean button, which ensures that they work in the background, even if you accidentally hit "Close all." Regular memory cleaning is useful if you notice that the phone is slowing down, but it doesn't make sense to do it every minute. RAM is designed to be busy, speeding up access to frequently used data. MIUI The interface and logic of background processes may vary depending on the firmware version. MIUI 12 or 13 may face more aggressive process killing than users of the newer versions. HyperOS's new shell also makes its own adjustments to energy management algorithms. For example, newer versions have introduced a feature called Memory Extension, which uses a portion of the internal storage as virtual RAM, which allows more applications to be kept in the background, but can slightly reduce the overall system response rate when working with memory. If you upgrade to the latest version of the system and notice that the battery is running out faster, try resetting the optimization settings. Often after a major update, the system re-indexes files and rebuilds databases, which in the early days causes increased resource consumption. 💡Every version MIUI It has its own optimization features, so there is no universal button "optimize everything" - you need an individual approach to the configuration of each smartphone (FAQ) Is it safe to completely disable background processes for all applications. If you completely shut down the background, it'll disrupt alarm clocks, timers, navigation, and instant messaging, and the system can start to get unstable, and why does it reappear in the background after you shut down the app? Many apps have self-healing mechanisms or are linked together (like Google services), and to prevent this, not only shutting them down, but also banning auto-start and background activity in settings. Does turning off background modes affect internet speed? Yes, it can be positive. If there are a lot of traffic-consuming programs running in the background, releasing the link can make the Internet in an active application faster and more stable. Should we use third-party software to clean the background? Most of the time, this is not necessary. Embedded facilities MIUI They do the job more efficiently. Third-party cliners themselves often hang in the background and consume the battery in an attempt to “optimize” the system.
