MIUI Daemon on Android Xiaomi: what is the program, how does it work and can it be removed?

If you’ve ever looked into the list of running processes on a Xiaomi, Redmi or smartphone POCO, I'm sure you've noticed a strange name — MIUI Daemon (or com.miui.daemon) is a system component that raises a lot of questions: what does it do, why does it consume resources, can it be turned off, is it not a virus? MIUI Daemon, how it relates to the shell work MIUI, We will give you clear recommendations for working with him.

Let’s warn you right away: despite the suspicious name (the word “daemon” is associated with malware), this process is a legitimate part of the firmware developed by Xiaomi. However, its behavior is not always transparent to the user, and in some cases it can cause increased battery consumption or unstable system operation. MIUI Daemon from potential problems and what to do if the process begins to behave suspiciously.

What is MIUI Daemon and why is it necessary?

MIUI Daemon (or com.miui.daemon) is a system service that runs in the background on all devices running the shell. MIUI. Its main task is to provide interoperability between the Android kernel and proprietary Xiaomi features, such as:

• 🔄 Automatic updates (checking and installing firmware, security patches).
• 📱 Performance optimization (memory management, cache cleaning, background process adjustment).
• 🔋 Battery management (activation of energy saving modes, charging control).
• 🛡️ Security (virus scanning, blocking suspicious activity).
• 🌐 Synchronization with Xiaomi servers (cloud backups, push notifications).

In fact, MIUI Daemon acts as a “mediator” between standard Android services and unique chips. MIUI. Without it, many of the functions of the shell would either not work at all or would behave in an unstable way:

• 🔄 Automatic reboot of the device after installing updates.
• 📉 Cleaning RAM according to the schedule (the function “Memory Cleanup” in the settings).
• 🔋 Adaptive limitation of application background activity in energy saving mode.

But here lies the main problem: MIUI Daemon often works aggressively, consuming up to 5-15% CPU And sometimes you can wake up the processor, even when you're in standby mode:

• ⚡ Increased battery consumption (especially on older models with weak iron).
• 🐢 Slowdown with active use of the smartphone.
• 🔥 Overheating (if the process is looped).

How to check activity MIUI Daemon on his Xiaomi

To see how much more MIUI Daemon affects your device, you can use built-in tools MIUI Or third-party utilities. Here's the step-by-step instruction:

1. Open "Settings» → «The phone» → «Version. MIUI» and tap the version number several times to activate Developer Mode.
2. Go back to the main settings menu, find a new section for developers, and turn on the Process Statistics option (or Debugging by Debugging). USB, if detailed information is needed).
3. Go to Settings. → Annexes → Application management → Processes (the path may differ depending on the version) MIUI).
4. Find com.miui.daemon and see how much it consumes. CPU, RAM and batteries.

For more detailed analysis, third-party applications can be used:

• 📊 CPU Monitor – shows the load on the processor in real time.
• 🔋 BetterBatteryStats – analyzes battery consumption by process (requires) ROOT).
• 🛠️ DevCheck – displays complete system information, including background services.

If you see that MIUI Daemon is constantly consuming more than 20% CPU Or it keeps the processor active even when the phone is idle, which is a cause for concern, and normally it should wake up periodically (once every few minutes) and immediately "fall asleep" back.

⚠️ Note: Some of the firmware (especially custom) MIUI Daemon can conflict with modified cores or Magisk modules. ROM or root-right smartphone began to overheat — first of all check the activity of this process.

MIUI Daemon and battery: why it drains the phone

One of the most common complaints about MIUI Daemon is a higher battery consumption, and the thing is, the process is responsible for the background optimization of the system, which means that you're using it:

• 🔄 Periodic scanning of installed applications for updates.
• 🧹 Cleaning the cache (including in the background).
• 📡 Synchronization with Xiaomi servers (notification checks, cloud backups).
• 🔋 Charging control (e.g., limiting current when reaching 80% in Smart Charging mode»).

The problem is that on weak or outdated devices (e.g. Redmi). 4X, Redmi Note 5) This can take too much time, and it doesn't go to sleep, and it actually sits down even when you're standing still. MIUI 12/13, Where Background Optimization Has Been More Aggressive.

If your device falls into the category of “critical consumption,” try the following steps:

1. Turn off automatic optimization in battery settings (Settings) → Battery. → Settings → Optimization).
2. Limit background activity for MIUI Daemon via Settings → Annexes → Application management → Threefold → Background activity.
3. Update the firmware to the latest version – in new versions MIUI Often correct bugs with increased consumption.

💡

If you turn off the optimization, the battery goes down even faster, you can put it back. MIUI Daemon, and in another process (e.g. mediaserver or android.system).

Can I remove or disable MIUI Daemon?

Technically, deletion or complete disconnection MIUI Daemon is possible, but it's highly discouraged. MIUI, and its deactivation may result in:

• 🚫 Failure to update firmware (including security patches).
• ⚠️ Failures in the operation of energy saving (the battery will go down even faster).
• 🔄 Restart freezes (the process is responsible for correct system shutdown).
• 📵 Loss of functions like “Smart Charging” or “Memory Cleanup».

However, if you are sure that MIUI Daemon is a source of problems, there are several ways to reduce its impact:

Method 1: Limitation of the ADB (rootless)

You can disable auto-start the process with a command ADB:

adb shell pm disable-user --user 0 com.miui.daemon

This will result in the loss of some functionality. MIUI. To get it all back, do it:

adb shell pm enable com.miui.daemon

Method 2: Freeze with Magisk (with root)

If you have ROOT-You can freeze the process using Magisk or Titanium Backup:

⚠️ Note: Some devices are frozen MIUI Daemon leads to an infinite bootloop. Before experimenting, back up through the backup. TWRP!

Method 3: Transition to custom firmware

If MIUI Daemon is too much interference, a radical solution is to install firmware without MIUI, for example:

• 🤖 LineageOS (Pure Android).
• 🔥 Pixel Experience (with features from Google Pixel).
• ⚡ ArrowOS (lightweight and fast).

They're not. MIUI Daemon, but no Xiaomi-branded chips (like Game Turbo or Second Space).

💡

Removal MIUI Daemon is a last resort, and in 90% of cases, you can fix the problem by setting up your optimization or updating your firmware.

MIUI Daemon and Security: A Virus or a Legitimate Process?
