How to disable or remove the application on Xiaomi Redmi Note 9: system and user

Xiaomi Redmi Note 9 is one of the most popular mid-range smartphones, but even it is slowly slowing down due to the accumulated unnecessary applications. Many users are faced with the problem of how to get rid of pre-installed MIUI services that can not be removed in the standard way, or how to properly deactivate the background processes that eat up battery power. In this article, we will analyze all available methods from simple disconnection to complete removal (including hidden system tools).

It’s important to understand the difference between the terms: Deletion erases an application from the device forever (perhaps not for all system programs), and shutting down only suspends it, freeing up RAM. On the Redmi Note 9 with MIUI 12-14 firmware, both options are available but require different actions. We’ll also look at which applications can be safely deactivated and which ones should not be touched – so as not to disrupt the stability of the system.

Why Xiaomi Redmi Note 9 apps aren’t removed in the standard way

The main reason is the manufacturer's policies and MIUI architecture. Most preinstalled applications (e.g. Mi Browser, Mi Video, GetApps) are system-based. They can't be removed through the Settings menu → Applications, as they are integrated into firmware. Here are the key limitations:

• 🔒 Reset protection: Xiaomi blocks the removal of critical services (such as Security or Mi Account) to avoid unstable operation.
• 📦 Version. MIUI: On the Redmi Note 9 with MIUI Global or MIUI China's list of "unremovable" apps differs, with the Chinese version often missing Google Play Services.
• 🛡️ Security: Some applications (such as Cleaner) are associated with the kernel of the system and their removal may lead to update errors.

However, even system applications can be turned off – this will remove them from the menu, stop background processes and free up to 10-15% of RAM (according to the tests on the Redmi Note 9 Pro with 6 GB of RAM). Full removal is possible only with root rights or through ADB – we will talk about this below.

⚠️ Disabling apps like Mi Share or Game Turbo won’t hurt, but deactivating the System UI Or the Android System will lead to a brick in the phone. Always check the name of the package before you act!

Method 1: Standard shutdown via MIUI settings

The safest method, which does not require additional tools, is suitable for most user and part of the system applications, the instructions are relevant for the Redmi Note 9 on MIUI 12-14:

1. Open Settings → Applications → Application Management.
2. Find the app you want (such as Mi Music or Facebook).
3. Slip on it and select Disable (if the button is inactive – the application is critical to the system).
4. Confirm the action in the dialog window.

Once disabled, the app will disappear from the menu, but will remain in the device memory. its data (cache, settings) will also be stored, this will allow the program to return to work later if necessary. To completely remove user applications (installed by you), use the Delete button in the same menu.

Some applications (such as Google Play Services) may cause errors in the operation of other services after deactivation. If notifications stop coming or synchronization does not work after deactivation, return the application to its original state through the same Application Management section.

Method 2: Remove system applications via ADB (without root)

For advanced users who are ready to work with the command line, the method allows you to completely remove most system applications, but requires a connection to a computer and enable debugging over USB.

What you need:

• 🖥️ A computer with installed Xiaomi drivers and ADB Tools (you can download from the official Android website).
• 📱 Redmi Note 9 with debugging enabled USB (Settings → The phone. → Version. MIUI → 7 times tap to unlock the developer mode, then Settings → Additionally. → For developers → Debugging by USB).
• 🔌 Cable USB (preferably original).

Step-by-step:

1. Connect the phone to the PC and confirm the debugging permission on the smartphone screen.
2. Open the command prompt (Windows) or terminal (macOS/Linux) in the folder with ADB.
3. Enter the command to check the connection: Adb devices Must appear serial number of your Redmi Note 9.
4. Find out the exact package of the application (for example, for Mi Browser it is com.android.browser).
5. Delete the application by command: adb shell pm uninstall -k --user 0 name packet For example, for Mi Music: adb shell pm uninstall -k --user 0 com.miui.player

Once the command is executed, the application will be deleted for the current user (without affecting system files).

adb shell cmd package install-existing name packet

⚠️ Note: Some packages (e.g. com.xiaomi.finddevice) will disable the phone search function via Mi Account when removed. Make a list of the packets to be removed in advance and check their destination!

Method 3: Complete removal with root rights (for experienced)

Root rights give you complete control of the system, but improper actions can lead to a device blink. On the Redmi Note 9 root is obtained through unlocking the bootloader and installing Magisk or SuperSU.

Pre-launch warnings:

• 🔓 Unlocking the bootloader will reset all data on the phone.
• 🛠️ Xiaomi may refuse warranty repair after receiving root.
• 🔄 Updates MIUI You have to install it manually.

If you are prepared for risks, follow the algorithm:

1. Unlock the bootloader through the Mi Unlock Tool (instructions on the official Xiaomi website).
2. Install a custom recap (TWRP) for your model (Redmi Note 9 has merlin encoding).
3. Sweep Magisk through the Recovery to get root.
4. Use Root Explorer or Titanium Backup to remove system applications (just move files from /system/app or /system/priv-app to another folder or delete).

Example: to delete Mi Browser, find /system/app/Browser and delete its contents, and once you reboot it disappears forever, and you need to refashion your phone to recover it.

💡

Before you delete your system files, back up /system via TWRP, which will allow you to restore your phone if something goes wrong.

How to Free Up Your Place After Disabling Applications

Even after deleting or disabling applications, their cache and data can take up space, to completely clear the memory:

1. Go to Settings. → Warehouse.
2. Slip on Clean in the section "Junk files".
3. For deep cleaning, use Settings → Applications → [Select App] → Storage → Clear cache/data.

We also recommend:

• 🗑️ Remove downloads from the Download folder (use Files or ES Conductor).
• 📸 Transfer photos and videos to a memory card or cloud (Google Photos, Mi Cloud).
• 🎵 Delete unused audio files (music app cache can weigh gigabytes).

💡

Regularly cleaning the cache and deleting unnecessary files can free up to 30% of memory without risk to the system. Start with the safest methods (clean downloads, cache), and only then move on to disabling applications.

What apps on Redmi Note 9 can be turned off without risk

Not all system applications are equally useful, but here are some programs that you can safely disable or uninstall without disrupting the Redmi Note 9:

If in doubt, check the assignment of the package through Google searches or specialized forums (e.g. XDA Developers or 4PDA).

What to do if after disabling applications the phone began to work worse

Sometimes, when you deactivate your system services, you get a sudden, unexpected consequence: overheating, battery failure, or interface errors.

1. Enable the app back through Settings → Apps (if it is disabled rather than removed).
2. Reset to factory settings (Settings → Phone → Settings Reset) if the errors are critical.
3. Update MIUI to the latest version – sometimes bugs are fixed in new builds.
4. Check background processes through Settings → Battery → Battery usage. It’s possible another app has started to consume more resources.

If the problem occurs after removal via ADB, restore the packet by command:

adb shell cmd package install-existing name packet

For example, for Mi Browser:

adb shell cmd package install-existing com.android.browser

⚠️ Note: If after manipulating the system files Redmi Note 9 stopped turning on or stuck on the logo, try to go to Fastboot Mode (click Power). + Volume down) and flash the phone through the Mi Flash Tool.
