Have you ever looked into the list of running processes on your Xiaomi smartphone and noticed a strange application? miui_daemon? It's constantly appearing in Task Manager, consuming resources, but it's not on the application menu. Is it a virus, a system component, or something in between? Why? MIUI It is so hard to hide it from the user?
This process is one of the most mysterious elements of firmware MIUI, And it's something that even the most experienced users know surprisingly little about, unlike the com.android.systemui or miui.home, miui_daemon It doesn't have a graphical interface, it doesn't show up in the settings, and it interacts actively with the core, and it's often suspicious of its behavior, like waking up and eating the battery, disappearing for days, reappearing after the upgrade. In this article, we will explore what this demon actually does, why Xiaomi doesn’t document its work, and whether it’s safe to get rid of it.
What is it? miui_daemon And why do you need him in MIUI?
MIUI Daemon (full name of the process is com.xiaomi.miui.daemon or miui_daemon) — It is a background system service that performs critical tasks in managing the hardware and software components of a smartphone, and unlike conventional applications, it operates at the root level and is closely integrated with the Android kernel. Its main function is to provide communication between the user interface. MIUI Xiaomi low-level services that cannot be implemented through standard API Android.
Simply put, it’s a bridge between what you see on the screen and what happens “under the hood” of your Redmi, POCO Without it, many firmware chips wouldn't work:
- 🔄 Dynamic performance tweaking – when the smartphone automatically switches between battery, cooling or gaming acceleration modes.
- 📡 Antenna Control – Signal Optimization Wi-Fi/4G/5G depending on your location.
- 🔋 Charging control – limiting current when overheating or enabling fast charging only on original chargers.
- 🛡️ Protection against unauthorized access – blocking certain functions (e.g, ADB or Fastboot) in case of suspicious activity.
Interesting fact: miui_daemon appeared in early versions. MIUI 7 (2015 It was part of another process, miui.guardprovider, which Xiaomi has since decomposed into a separate module to reduce system load and improve stability. MIUI 12/13/14, including models POCO and Black Shark.
How miui_daemon Affects battery and performance?
The main problem with this process is that it's an unpredictable energy consumption. miui_daemon It may be "wake up" once in a while. 5–10 minutes and keep the processor active, resulting in battery drain 5–15% And the problem gets worse after the updates. MIUI, When the demon starts indexing new system files or optimizing sensors.
To see if it is your Xiaomi fault, check out the following:
- Open Settings → Battery → Battery Use.
- Select the graph and select Show System Processes.
- Find it on the list. miui_daemon or com.xiaomi.miui.daemon.
- Pay attention to the column. CPU — If the value is above 1-2%, the process is actively working.
| Script | Normal consumption | Increased consumption | Possible cause |
|---|---|---|---|
| Standby mode (screen off) | 0–0.5% | 2% and above | Synchronization Error with Xiaomi Servers |
| Active use (social networks, messengers) | 0.5–1.5% | 3% and above | Conflict with optimization MIUI specific application |
| Games or videos | 0–1% | 2% and above | Incorrect operation of the thermal control |
| After the MIUI update | 1–3% (temporary jump) | 5% or higher (longer than 24 hours) | Mismigration of data between versions |
It is important to understand that miui_daemon It's not always to blame for battery life. It's often just doing things that other processes have initialized. For example, if you've turned on dual applications or second space, the demon will actively control the data isolation, which will inevitably affect the power consumption.
💡
If miui_daemon consume 5% If you have a battery every day, try turning off the Auto-Optimization feature in the battery settings.
Can I turn it off? miui_daemon without consequence?
Technically, but with reservations, because it's a system process, it can't be removed or stopped by standard Android tools.
- 🛠️ Through ADB (Requires an unlocked bootloader: adb shell pm disable-user --user 0 Risk: After that, sensors, fast charging and some camera features may stop working.
- 🔧 Magisk (root required): You can freeze the process via the App Systemizer or Disable Flags module.
- ⚙️ Through Developer Settings (less radically): Disable Optimization MIUI and Analytics of use in Settings → The phone. → Version. MIUI (7 times tap to open the developer menu).
⚠️ Attention: If you turn off miui_daemon on devices with a Qualcomm processor (for example, Xiaomi) 12 pro POCO F4), Quick Charge support may be lost on MediaTek (e.g. Redmi Note) 11) Sometimes the VoLTE stops working.
The safest way to reduce the activity of the demon is to reset the battery optimization settings:
Remove the Security app cache (com.miui.securitycenter)|Turn off "Adaptive Brightness" in the screen settings|Turn off "Auto-Optimization" in the battery settings|Reboot the phone.-->
Connection miui_daemon securely
One of the most controversial aspects of this process is its role in telemetry collection, according to independent researchers (e.g. Exodus Privacy Project), miui_daemon The following data can be transmitted to Xiaomi servers:
- 📱 Information about the device model and firmware version.
- 📡 Network Connection Status (Wi-Fi, Mobile Internet).
- 🔋 Charging data (connection/disconnection time, charger type).
- 🌡️ Processor and battery temperature.
However, unlike the scandals of 2020-2021, when Xiaomi was accused of covert surveillance, now this data is anonymized and sent only when the function “Improving” is enabled. MIUI (You can turn it off in Settings. → Memory. → Auto-run. In fact, in versions. MIUI 14 for global regions (EEA) Telemetry collection is disabled by default.
If you are concerned about privacy, check the following settings:
- Settings → Confidentiality → Special permits → Access to use data → turn off for all applications.
- Settings → The phone. → Updating the system → Settings (⚙️) → Join the Improvement Program MIUI → turn off.
- Settings → Accounts. → Mi Account → Synchronization → disable unnecessary items.
⚠️ Attention: On devices with MIUI China ROM (For example, purchased on AliExpress without global firmware) miui_daemon It can send data even when settings are turned off. The only way to stop it is to flash Global. ROM or Xiaomi.EU.
How to distinguish the real miui_daemon virus?
Because the process works in the background and has no icon, scammers often disguise malware as a background, here's how to check that you have the original system demon:
| Sign. | Real. miui_daemon | Fake (virus) |
|---|---|---|
| The path to the file | /system/priv-app/miui_daemon/ or /system/app/ | /data/app/ or unknown folder |
| Signed | Signed by Xiaomi Inc. (checked through the ADB) | Unknown certificate or no signature |
| Traffic consumption | Minimum (up to 10 MB/day) | High (100)+ MB/day) |
| Time to work. | Short-term bursts (1-5 seconds) | Constant activity (minutes) |
To verify the authenticity of the process:
- Install the App Inspector app (e.g. com.rb.appinspector).
- Find it. miui_daemon on the list and check the path to APK.
- If the path begins with /data/ — it 100% Remove it through the virus. ADB: adb shell pm uninstall --user 0 [packet]
Also, pay attention to unusual behavior:
- 📥 Unknown notifications of “system updates".
- 🔗 Redirecting to suspicious sites when connecting to Wi-Fi.
- 💰 Debiting funds from the account (if a bank card is tied).

Interaction with other system processes
MIUI Daemon doesn't work alone -- it's closely linked to other components of the firmware. Here are the key dependencies:
- 🔄 miui.guardprovider -- security and permissions. miui_daemon, This process may start to produce errors when installing applications.
- 📊 com.miui.analytics — collects usage statistics. Without the demon, the analytics will be incomplete, but it's uncritical.
- 🔋 com.miui.powerkeeper - manages energy saving. miui_daemon It can lead to sudden reboots.
- 🛡️ com.lbe.security.miui - antivirus and protection. When you turn off the demon, scanning files will work slower.
Interesting fact: on devices with HyperOS (new firmware from Xiaomi, which replaced the new version of the device). MIUI into 2026 year miui_daemon perform hyper_daemon. Its architecture is more transparent and it has less impact on the battery.If you have the option to upgrade to HyperOS, it could solve the high-resource problem.
To check the interaction of processes:
- Install Termux and execute the command: su -c "ps -A | grep miui"
- If there are processes with Zombie status (Z-labeled) on the list, it indicates a malfunction in their work.
- Restart your phone – if Zombie processes are left, you need to reset your settings.
💡
Shutdown miui_daemon On custom firmware devices (like LineageOS) it doesn’t make sense – it’s replaced by Google or the community.
What to do if miui_daemon malfunction?
If the process leads to overheating, freezing, or rapid discharge, try the following steps:
- Clear the cache of system applications: adb shell pm clear com.miui.securitycenter adb shell pm clear com.xiaomi.miui.daemon
- Reverse to the previous version MIUI (If the problem started after the update. For this: Download the old firmware from xiaomifirmwareupdater.com. Go to Settings → The phone. → Updating the system → Three points. → Select a Service Package.
Reset the settings to factory.
