Redmi 9 smartphones running MIUI are often pre-installed with a set of programs that the user doesn’t always need. Many of them consume RAM in the background, reducing overall device performance. Gadget owners often wonder how to safely limit the operation of such services without obtaining superuser rights.
In this article, we will discuss proven methods of stopping system processes and third-party applications. You will learn to distinguish between components that are safe to disable and those that can lead to unstable system operation.
Analysis of pre-installed software and system processes
The first step to optimizing is understanding what is installed on your device. MIUI is famous for its aggressive approach to background processes, but also contains a lot of services that seem unnecessary.
Some apps, like Google Play Services or Xiaomi system components, are critical to notifications and sync, and forced shutdowns can disrupt messaging and email functionality, but there are a number of programs, like MSA (advertising service) or Analytics, that can be deaktivirovat'.
⚠️ Warning: Disabling system components that are responsible for telephone communication or interface operation can cause a cyclical reboot of the device.
Use built-in tools or third-party tools to analyze it, and you can see in the settings menu which programs have been using the most power over the past day, which will help you to make a list of candidates for forced shutdown.
Standard method of disabling through Android settings
The basic way to manage programs is available to every user without installing additional software, which allows you to temporarily or permanently stop the work of selected components, first you need to go to the appropriate section of the settings menu of your Redmi 9.
Find Settings → Applications → All Apps. In the list that opens, select the program you want. If the "Disable" button is active (not grey), then the system allows you to stop the component without the risk of critical errors.
- 📱 Open your smartphone settings and go to the application management section.
- 🔍 Find the target application you want to stop in the list.
- 🛑 Click the “Disable” button and confirm the action in the pop-up window.
Once you do this, the application icon will disappear from the desktop and its processes will no longer load the processor. However, this method does not work for all system components.
💡
If the Disconnect button is inactive, try first clicking Stop and then Remove Updates, after which the Disconnect button may become available.
Use of Developer Mode and ADB
When standard methods fail, USB debugging comes to the rescue, which requires connecting your smartphone to your computer and using console commands, and allows you to disable even the system packages that are hidden from the average user in the MIUI interface.
First, activate the hidden menu. Go to Settings → About Phone and quickly click on the MIUI build number seven times. After the message “You’ve become a developer” appears, go back to the settings menu, find the “Additional” section and select “Developers” and activate the “Debug by USB” option.
adb shell pm disable-user --user 0 com.miui.analyticsThis command, for example, completely disables the system analytics service, you need to install ADB Platform Tools on your computer and connect your phone with a cable, and you need to confirm access to debug in the permission list on your smartphone screen.
List of safe packet removal
An error in syntax can cause a command to simply fail, but an incorrect packet name can hide an important system element.
Comparison of application management methods
The choice of deactivation method depends on your goals and level of training. Below is a table comparing the available options for interfering with the Xiaomi Redmi 9 system.
| Method | Difficulty | Risk to the system | Efficiency |
|---|---|---|---|
| Android settings | Low. | Minimum | Medium |
| ADB team | Tall. | Medium. | Tall. |
| Third-party launchers | Medium | Low. | Low. |
| Root rights | Very high. | critical | Maximum |
As you can see from the table, using ADBs provides the best balance between control and security if you act carefully. Root rights give you full control, but they are unwarranted and can disrupt banking applications.
The average user is advised to limit himself to the first two methods: Deep interference with the file system is not necessary for comfortable use of Redmi 9 in everyday tasks.
Limitation of background activity and battery
Even if you can't turn an app off completely, you can significantly limit your appetites. Android and MIUI provide flexible tools for managing your power consumption, and this is especially true for social media and instant messengers.
Go to Settings → Battery and Performance → Energy Consumption. Here you can select an energy saving strategy for each individual program. Setting a restriction in the background will prevent the application from running when the screen is off.
- ⚡ Select “No Limits” for important messengers only to avoid missing messages.
- 🔒 Set a strict limit for games and heavy apps that you rarely use.
- 📉 Use the “Energy Saving” mode for background synchronization of mail and cloud services.
Also worth paying attention to auto-run. The Security app on your Xiaomi has a section called Permissions» → «Autostart. Disabling this setting will prevent the program from starting with the phone turning on.
☑️ Optimization of background processes
Possible risks and system recovery
Incorrect system management can lead to unpredictable consequences, most often users face loss of sound, inability to take a screenshot or failures in the interface, it is important to know how to get it back.
If you have disabled the application through settings, it is easy to turn it back on in the same way. If you use ADB commands, you will need to reconnect to the computer and enter a command with the disable-user replaced by enable.
⚠️ Warning: If your phone stops turning on or is not working properly, you may need to reset completely to factory settings (Hard Reset).
Before starting any experiments, it is recommended to back up important data. Synchronizing with a Google Account or Xiaomi cloud will allow you to quickly restore contacts and photos in the event of a crash.
💡
Always write down the names of the packets you manually disable, which is the only way to quickly restore the system in case of an error.
