Poco X3 series smartphones, whether NFC or Pro, are known for their powerful hardware and fast charging, but the MIUI software shell often raises questions from users because of the abundance of preinstalled software. A lot of background processes, advertising modules and unnecessary system utilities can not only take up precious space in memory, but also significantly affect the battery life of the device. Owners often face a situation where standard system tools can not remove or even hide some components.
Fortunately, the Android operating system provides mechanisms to manage installed packets, allowing them to be put into a “freeze” state, which effectively stops the application from running at start and stops the background processes without removing the installation file completely, an approach that is considered the safest way to optimize, since at any time it allows you to return everything to its original state without losing data or needing to flash it.
In this article, we will take a look at all the available ways to deactivate software on Poco X3. We will look at the standard interface settings, the use of advanced capabilities for developers, as well as more advanced methods with a connection to a computer. You will learn to distinguish between critical system components from safe “junk” that can and should be turned off to speed up your gadget.
Analysis of pre-installed software and risks
Before you start taking action to disable packages, it’s important to understand what you’re dealing with. Xiaomi’s MIUI shell contains hundreds of system processes, many of which have complex names and non-obvious features. Blindly disabling unknown services can lead to unstable device operation, cyclical reboots, or even a complete system failure to boot.
All applications on a device can be divided into three categories: user, system (non-critical) and system (critical). The first are programs that you installed yourself or that can be removed in a standard way through settings. The second are often analytics services, advertising or brand-specific functions that do not affect the basic functionality of calls and the Internet.
⚠️ Warning: Never disable components that have the words "Security", "SystemUI", "Settings" or "Framework" in their name, which can cause the phone to turn into a "brick" or stop responding to touches on the screen.
The third category is the core of the system, without which the Poco X3 will not be able to function, including telephony, memory management, display drivers and touchscreen, and experienced users recommend that you carefully analyze packages through search engines before making any changes, using their exact package name to make sure that the procedure is safe.
Standard methods of disconnection through MIUI settings
The simplest and most secure way to manage applications is built directly into the operating system interface, which does not require a computer connection, installing additional software, or obtaining superuser rights, but the functionality of this method is limited: it allows you to disable only those applications that the developer of the MIUI shell has deemed safe for deactivation.
To get started, go to your Poco X3’s settings menu. Find the Apps section, then select All Apps. This is the full list of installed software. Scroll through the list and find the application you want to deactivate. Note that system applications are often hidden by default, so make sure that display filters (usually three dots in the corner) have an option to show all processes.
Once you select the right item, you will open a page with information about the application. If the program allows deactivation, the Disable (or Disable) button will be active at the bottom of the screen. Clicking on it will start the process of stopping the service. The system will warn you that the application will stop working and disappear from the list of recent tasks. Confirm the action, and the application icon will disappear from the desktop, and the process will be frozen.
- 📱 Open the settings and go to the Application Management section to access the list.
- 🔍 Use a name search to quickly find the system process you want among hundreds of others.
- 🛑 The “disconnect” button will be gray (inactive) if the system considers the component to be vital.
- ✅ After disabling the application can be reactivated in the same menu by clicking the button "Enable".
💡
Before a mass application shutdown, create a full data backup via the Mi Cloud cloud or locally to your computer to have a rollback point in case of errors.
Importantly, the standard method prevents many Xiaomi ad services (such as MSA or Mi Credit) from being disabled, as they are deeply integrated into the system. To combat them, more radical measures will be required, which will be discussed below. However, to basic clean up unnecessary software like Google Movies, YouTube (if you do not use them), or regional services, this is quite enough.
Using Developer Mode for Extended Control
If the standard interface is not enough, you can activate a hidden menu for developers, which does not give direct access to disabling all applications, but allows you to manage processes more flexibly, in particular, limit background activity and animations, which indirectly helps in combating heavy software, Activating this mode is the first step to deep customization of the Poco X3.
To open access to hidden features, go to Settings → About Phone. Find the MIUI version bar and quickly click on it 7-10 times in a row. A pop-up notice will appear that you have become a developer. Then a new Developer item will appear in the main settings menu, in the Additional section.
Inside this menu, we're interested in the App section, where you can find the option to Do Not Stay Activity or Background Process Limit. 1-2 process or complete prohibition of background activity can significantly speed up the operation of an old or overloaded device, although it can lead to more frequent reboot of tabs in the browser. USB, which is necessary for subsequent connection to the computer.
| Function | Description | Impact on the battery |
|---|---|---|
| Don't stay active | Destroys activity immediately after leaving the application | Reduces the cost |
| Process limit | Limits the number of working in the background of applications | substantially reduces |
| Window animation | Disabling the visual effects of the interface | It's a little lower. |
Using developer mode requires caution. Changing rendering settings or DPI scale can make the interface unreadable or cause touchscreen failures. If you accidentally change the setting and the screen becomes unmanageable, try quickly restarting the device or milking a few minutes — sometimes the system itself resets critical errors.
Deep Cleaning through ADB (Android Debug Bridge)
The most effective and professional way to remove or disable system debris on Poco X3 use of the instrument ADB (Android Debug Bridge. This method allows you to interact with the operating system at the command line level, gaining access to functions hidden from the average user. USB-cable.
The first step is to prepare the smartphone. As mentioned earlier, you need to activate the developer mode. Then you need to turn on the Debugging over USB menu for developers. When you connect the phone to your computer, you will see a request for debugging permission on the smartphone screen — be sure to tick the "Always Allow from this computer" box and confirm the action.
On your computer, you need to download and unpack ADB platform tools from Google's official website. Once you connect your phone, open the command line (Terminal or CMD) in the ADB folder and type in the adb device command. If the device is correctly defined, you will see its serial number and device status. You can now go to the package list.
adb shell pm list packagesThis command will display a complete list of all packages installed. To find a specific application, use a filter, for example: adb shell pm list packages | grep google. To disable the found package, the command adb shell pm disable-user --user 0 name.packet is used. For example, to disable the analytics service, the command will look like this:
adb shell pm disable-user --user 0 com.miui.misys- 💻 Install the drivers. ADB on the computer for correct recognition of the smartphone.
- 🔌 Use an original or quality cable USB stable-connection.
- 📝 Keep a list of disable packets to know what has been changed.
- 🔄 To return the application, use the command adb shell pm enable name.packet.
☑️ Preparation for work with ADB
The good thing about ADB is that it doesn't require root rights, it doesn't violate the integrity of the system partition. You just change the status flag of the application for the current user, which means that even after you reset the settings to Factory Reset, the applications can come back, but they won't behave in the normal course of operation, and that's the perfect balance between security and efficiency.
Automation of the process with Universal Android Debloater
For those who don’t want to mess around with manually typing commands into the console, there are graphical shells for ADB. One of the most popular and reliable is Universal Android Debloater (UAD) utility, an open source application that automatically identifies your device’s model (in our case, Poco X3) and offers a list of secure apps to remove or disable.
The UAD is simple: you plug your phone in, you run it on your PC, and it scans the packet list. The interface is divided into categories: Recommended, Safe, Expert, and Dangerous. Each application is given a brief description, and you just tick off the unneeded software (e.g., Mi Video, GetApps, Facebook) and click Uninstall or Disable.
⚠️ Warning: Even in automated tools, you should not blindly trust the category "Safe." Always read the description of the feature before you turn it off, especially if you are not sure what a particular package is responsible for.
The main advantage of these gates is the ability (in one click) to apply settings for a whole group of applications, and the program allows you to back up a list of packages before making changes, if after cleaning the phone starts to behave strangely, you can restore the original state with a single button, which significantly reduces the risk of damage to the system.
What if the phone stops turning on after cleaning?
Note that UAD only works when the phone is connected to the computer. Once the cable is turned off, all changes are stored in the smartphone memory. However, to re-activate applications, you will need to connect to the PC and run the utility again, since in the MIUI interface these applications can be hidden completely.
