How to Remove Facebook App Manager from Xiaomi: 5 Ways to Work

Facebook App Manager is the system application that Xiaomi preinstalles on most of its smartphones (Redmi Note 10/11/12, POCO X3/X4/X5, Mi 11/12, etc.) It is responsible for integrating Facebook services into the system: synchronizing contacts, notifications and background processes of the social network. However, many users are faced with the fact that the manager slows down the phone, consumes the battery and collects data without consent. In this article, we will discuss how to disable or remove it – from simple methods without superuser rights to radical methods using ADB.

It's important to understand that Facebook App Manager is not the same as a regular Facebook app. It can't be removed in the standard way through the Apps menu, because it's built into MIUI firmware. But there are workarounds — some require unlocking the bootloader or connecting to the PC, others work out of the box. We tested all methods on current versions of MIUI 14 (Android 12/13) and identified those that are guaranteed to work.

Why is Facebook App Manager a hindrance to Xiaomi?

According to a traffic analysis conducted by XDA Developers, Facebook App Manager can:

• 🔋 Spending until 5-7% It's a daily battery charge, even if you're not using Facebook, and it's constantly syncing data in the background.
• 🐢 Slow down the system 10-15% Multitasking (Redmi Note tests) 11 Pro+ Snapdragon 695).
• 📡 Transfer your activity data to Facebook even if your account is not linked (confirmed by Privacy International research).
• 🚫 Block some apps updates via Google Play due to conflicts with the services MIUI.

On the forums, Xiaomi users complain that after removing the manager:

⚠️ Note: On some models (POCO F3, Mi 10T) When Facebook App Manager is deactivated, Messenger notifications stop working, because it uses the system services to push notifications. If you care about messages from Messenger, consider alternative ways (see MicroG section).

Method 1: Disconnect via MIUI settings (without root)

The easiest and safest method is to deactivate the manager without deleting it completely, which will stop the background processes, but the application file will remain on the system.

Instructions:

1. Open Settings → Applications → Application Management.
2. Click on the three dots in the top right corner and select Show All Apps.
3. In the search box, type in Facebook App Manager (or Facebook Services on newer versions).
4. Slip on the application → Disable → Confirm the action.
5. Reboot the phone.

After the shutdown:

• ✅ Notifications from the notifications will cease to arrive Facebook/Messenger.
• ✅ Background activity will disappear (check in Settings). → Battery → Battery utilization).
• ❌ There will be no memory (files will remain).

On some firmware (MIUI 14 for POCO F4), after disconnection, the manager can self-repair after the system update, in which case move to the ADB method.

Method 2: Delete via ADB (without superuser rights)

If disabling didn’t work, you can uninstall the app entirely using Android Debug Bridge (ADB), a method that works on all Xiaomi models with the bootloader unlocked (not to be confused with root!).

What you need:

• 🖥️ Computer with Windows/macOS/Linux.
• 📱 Cable USB (preferably original).
• 🔧 Google's Platform Tools utility.
• ⚙️ Included Debugging by USB on the phone (Settings) → The phone. → Version. MIUI → 7 times to tap → return to additional settings → Developer parameters).

Step-by-step:

1. Connect the phone to the PC and confirm the debugging permission.


2. Open the command prompt (Windows) or terminal (macOS/Linux) in the folder with ADB.




3. Enter a command to check the connection:




adb devices




(Your device serial number should appear).




4. execute the command to remove:




adb shell pm uninstall -k --user 0 com.facebook.appmanager




5.To remove additional Facebook services:




adb shell pm uninstall -k --user 0 com.facebook.services

3. In the module settings, select com.facebook.appmanager and press Uninstall.
