Modern smartphones like the Xiaomi Redmi 9 come with a pre-installed set of programs that the user doesn’t always need, many of which run in the background, consuming precious CPU and RAM resources, which can slow down the device and quickly drain the battery, which is especially noticeable in mid-range models.
Fortunately, the Android operating system in the MIUI shell provides tools to control this process, so you can not only remove unnecessary programs, but also completely disable system components that cannot be erased by standard methods, which allows you to personalize the device to your needs and free up space.
In this article, we will take a look at how to safely deactivate software on your gadget. We will look at standard methods through settings, as well as more advanced ways for power users. Properly configured will help extend the life of your smartphone and make it more comfortable to use.
Analysis of pre-installed software on Redmi 9
Before we get into action, we need to understand what we're dealing with. Redmi 9 usually has a lot of apps from Google, Xiaomi and third-party partners, some of which are critical to the system, and others can be deaktivirovat without consequences.
System applications are often hidden from the eyes of the average user or marked as undeleteable. Attempting to disable an important component can lead to unstable interface operation or even a cyclical reboot.
💡
Always check the purpose of the application on the Internet before disabling it if you are not sure about its function.
All software can be divided into three categories: user, system and critical. User can be removed freely, system can be disabled, and critical software can be left unattended, and understanding these differences will save you from many problems.
- 📱 User-generated: Social networks, games, browsers installed by you or the manufacturer for advertising.
- ⚙️ System: Calculator, Recorder, Themes, Mi Videos that can be turned off if not used.
- 🔒 Critical: Task Manager, Systems UI, Google Play Services That Are Not Recommended Touch.
Standard method of disconnection through settings
The safest and easiest way to deactivate an unnecessary program is to use the built-in MIUI interface, which doesn't require superuser privileges or a connection to a computer, but is ideal for most optimization tasks.
First, you need to get into the application management menu, which shows the full list of all the software installed. The interface may vary slightly depending on the firmware version, but the logic remains the same for all Xiaomi devices.
☑️ Algorithm of action
Find the app you want and click on it, and you'll open a page with the information that you can use the control buttons, and if the program allows deactivation, the Disable button will be active, otherwise it'll be hidden or replaced with Delete.
Once you press the button, the system will alert you that the application will stop working, which means that its icon will disappear from the desktop and processes will stop, while the application data is stored, and you can always turn it back on.
Use of advanced MIUI settings
MIUI is known for its deep customization capabilities, which are hidden in the developer menu or special sections, and sometimes the standard path isn't enough to get to the deepest settings of a particular service.
Some firmware versions have the ability to control autoruns and permissions, which is effectively equivalent to disabling functionality. By restricting access rights, you can turn an unnecessary application into a non-working shortcut without touching its system files.
Hidden Functions of the Developer Menu
Also worth paying attention to is the Battery and Performance section, where you can adjust the behavior of each application in the background, setting a background restriction effectively freezes the program, keeping it from wasting resources.
Balancing charge savings and functionality is a key element in the Redmi 9 setup.
- 🔋 Go to the battery settings and select a specific application.
- 🚫 Set the "No Limits" mode only for important messengers.
- ❄️ For the rest of the software, select "Restriction of background activity".
Removing Systemic Garbage Through ADB
For advanced users who want to completely clear the system of embedded software, there is a method using Android Debug Bridge. This tool allows you to control the device from a computer at a deep level, bypassing the limitations of the interface.
Before you start, you need to enable USB debugging in the Developer Menu, which is a hidden partition that is activated by clicking seven times on the build number in the About Phone menu, without this step, the computer will not see the smartphone in debugging mode.
adb shell pm list packagesOnce you connect and input the commands, you can delete or disable the packet. The command to disable looks like an adb shell pm disable-user --user 0 packet name. This action hides the application for the current user without physically removing it from the system partition.
💡
The ADB method allows you to disable even those applications whose button in the phone settings is inactive, but requires caution.
The list of packages can be huge and it is easy for a beginner to get confused in the titles.It is recommended to use special graphical shells for ADB, such as Xiaomi ADB/Fastboot Tools, which simplify the process and show package descriptions.
Comparison of application management methods
The way you deactivate depends on your goals and your level of training, and each method has its advantages and risks, and to make it easier for you to decide, we have compiled a comparative table of basic approaches.
| Method | Difficulty | Security | Efficiency |
|---|---|---|---|
| MIUI settings | Low. | Tall. | Medium |
| Battery limitation | Low. | Tall. | Medium |
| ADB team | Tall. | Medium | Tall. |
| Root rights | Very high. | Low. | Maximum |
As you can see from the table, standard settings are suitable for most users. Using ADB gives more control, but requires technical knowledge. Obtaining Root rights, while giving full control, deprives of warranties and can disrupt banking applications.
Don't try to remove everything. Android is designed to keep some processes active for the rest of the components to work properly, and over-cleaning can lead to errors.
Possible risks and system recovery
Any interference with the operating system carries certain risks, and shutting down a key system process can cause the phone to stop responding to commands or go into an endless reboot.
⚠️ Warning: If the phone starts to behave inappropriately after the app is turned off, immediately return it.
If the device stops loading normally, you can try to log in to Recovery Mode. For Redmi 9, this is usually done by pressing the volume button and power button. In the recovery menu, you can try to reset or select Safe Mode.
If you've used ADB to turn off, you can restore access even without the screen turning on if the debugging is running. The adb shell pm enable name packet command will bring the application back to life. So always write down which packages you've modified.
In the worst case, when software methods don't work, you have to do a full factory reset, and that will delete all your data, so regular backups are a must before experiments.
