If you’ve ever looked into the Task Manager of your Xiaomi smartphone or analyzed active processes through the ADB, I think they probably have a mysterious name. MAB (This system component raises a lot of questions, whether it's responsible for updates, whether it's responsible for collecting telemetry, or something even more mysterious. There are dozens of conflicting opinions on the Internet, from "it's a virus" to "don't touch it or the phone will break».
In this article, we will understand what is MAB Xiaomi, in fact, why the company needs it, whether it can be removed or disabled, and what the consequences are, and we'll analyze official data, independent research and user experience to give a clear and well-grounded answer. If you want to optimize your smartphone or are just interested in the internal mechanisms MIUI — This information will be useful.
What is it? MAB Xiaomi: official explanation and real-world features
abbreviation MAB Miui Analytics and Behavior (Analytics and Behavior) MIUI). This is a system application that is built into the firmware of all modern smartphones Xiaomi, Redmi and POCO base MIUI. The company is positioning it as a tool for:
- 📊 Collect anonymous statistics about device usage (which features are popular, where users encounter errors).
- 🔄 Optimizing system performance based on behavioral data (e.g., preloading frequently used applications).
- 📲 Improve user experience through personalized recommendations (e.g., tips in the user experience) MIUI).
- 🔍 Diagnostic problems and send crash reports to Xiaomi (if the user has given consent).
But in reality, MAB It performs far more functions than claimed. Independent researchers (e.g., the team) XDA Developers have found that this component:
- 🕵️♂️ Monitors user activity in the system (which applications are opened, how often, and when you use them).
- 📡 Transfers data to Xiaomi servers even when the option “Send statistics” is disabled».
- 🔄 Manages background processes, including Forced Updates).
- 🛡️ Interacts with the security system MIUI, including firmware authentication.
It is important to understand that MAB — It's not a virus or a spyware in the classical sense. It's a legitimate component. MIUI, But with broad authority, which is not always transparent to the user, and their behavior depends on the region of the firmware, the version. MIUI even the model of the device.
Why Xiaomi Needs to Be Used MAB: Real Reasons and Hidden Motives
On the surface, Xiaomi explains the presence of MAB It's about taking care of the user, saying that it helps make the firmware better, but let's see what the real benefits of this component are for the company.
| Reason. | How it works. | Benefits for Xiaomi |
|---|---|---|
| Statistics collection | Monitors what functions MIUI More often used where failures occur. | It allows you to optimize firmware for real use cases, reducing the cost of testing. |
| Forced renewals | MAB can initiate the download of updates in the background, even if the user has disabled the auto-update. | Increases the percentage of devices on the latest version MIUI, Improves safety and compatibility. |
| Targeted advertising | Application usage data helps to show more relevant ads in system services (for example, in Mi Browser). | Increases revenue from advertising partners (e.g. Google, local advertisers). |
| Control of modifications | MAB checks system integrity and can block unofficial firmware. | It protects against piracy and unauthorized changes, which is important for partners (for example, Netflix requires Widevine certification). |
The one with the forced updates is particularly interesting, and many users complain that even after the auto updates are disabled, the settings are not updated. MIUI The system still downloads new versions of the firmware. MAB, It ignores user settings and follows its own logic, which is especially annoying for owners of older devices where new versions are available. MIUI slow down.
Another controversial issue is data collection, where Xiaomi claims that all statistics are anonymous, but studies show that the data is not available. MAB can transmit unique device identifiers (e.g, IMEI Android ID), This can be used to link data to a specific user, and in some regions (e.g. the EU) it may conflict with data protection laws (GDPR).
💡
If you are concerned about data collection, check your privacy settings in Settings → Memory. → Privacy. You can turn off the diagnostics, but that doesn't guarantee a complete shutdown. MAB
Can I remove it? MAB: technical possibilities and risks
Technically remove MAB It's possible, but it comes with a number of complexities and risks:
- 🔧 On non-rooted devices, removal is not possible — MIUI Restore the component in the next update.
- 🛠️ On rooted smartphones MAB can be removed through ADB or file manager with root rights.
- ⚠️ Removal can cause the system to work in an unstable way, especially if MAB integrated into critical processes (e.g. security updates).
- 🔄 In some firmware MAB Responsible for verifying Widevine licenses L1 (Needed for Netflix HD).
If you have decided to remove it MAB, Here is a step-by-step instruction for rooted devices:
☑️ Preparation for disposal MAB
- Open a file manager with root permissions (such as Root Explorer or Solid Explorer).
- Go to the folder. /system/priv-app/MiuiMab or /system/app/MiuiMab (The path may differ depending on the version MIUI).
- Delete the MiuiMab folder or rename it (for example, in the MiuiMab_bak).
- Reset the device.
Alternatively, the method of disconnection through ADB:
adb shell pm uninstall --user 0 com.miui.mab
adb shell pm disable-user --user 0 com.miui.mab⚠️ Note: On some devices (e.g. Xiaomi) 12T or Redmi Note 11) deletion MAB This could lead to loss of Widevine certification. L1, Why Netflix, Disney?+ Other services will only work in 480p. Before removing it, check if it is critical to you.
What happens if you turn off or remove MAB: consequences
Effects of removal MAB Depends on the device model and version MIUI. Here are the most common effects:
| Action. | Possible consequences | How to fix it |
|---|---|---|
| Removal through root | Notifications of updates cease to arrive MIUI. | Update manually through Settings → The phone. → Updating the system. |
| Disconnection through ADB | Some system applications (such as the Theme Store) may not work properly. | Restore. MAB or reset the application settings. |
| Removal on old devices (MIUI 10-11) | Accidental reboots or lags are possible. | Install custom firmware (such as LineageOS). |
| Removal on new devices (MIUI 13+) | Widevine loss L1 (no HD streaming). | Restore. MAB Or use Magisk to disguise yourself. |
The safest way to “disconnect» MAB without removal, limit its activity:
- 🔒 Turn off permissions for com.miui.mab in the application settings.
- 🚫 Block Internet access via NetGuard or built-in firewall.
- 📵 Limit background activity through Settings → Battery → Optimizing the battery.
On devices with MIUI 14 and newer complete removal MAB This can lead to blocking some features, such as Mi Share or Quick Apps. MAB Now integrated into the firmware integrity verification system.
What to do after removal MAB The phone has stopped updating?
Alternative ways to reduce the impact MAB stripped
If you don’t want to risk the stability of the system, but want to reduce activity MAB, There are several safe methods:
1. Disconnection through MIUI settings
Go to:
- Settings → Memory. → Privacy → Sending statistics – disable all options.
- Settings → The phone. → Sending Error Reports – Deactivate.

| Redmi Note 10/11 (MIUI 12-13) | Collects statistics and manages background processes. | Uncritical, but update notifications may be missing. |
| POCO F3/4 (MIUI for POCO) | Less aggressive than on the standard. MIUI. | Minimal risks, but possible lags in system applications. |
| Xiaomi Pad 5/6 | Controls optimization for tablet mode. | There may be problems with multitasking. |
On devices with MIUI for POCO (for example, POCO X3 Pro) MAB It is less intrusive, as the firmware is focused on “clean” Android, but even here the component is responsible for collecting telemetry, which Xiaomi uses to analyze the market.
On flagship models (for example, Xiaomi 13 Ultra) MAB It is closely related to HyperOS (a new firmware from Xiaomi), where removing it can lead to loss of features such as the use of a new firmware:
