MIUI Daemon on Xiaomi: The Hidden Process That Controls Your Smartphone

If you’ve ever looked into Xiaomi’s Task Manager or analyzed active processes through ADB, you’ve probably come across the mysterious name MIUI Daemon, which runs in the background but is rarely mentioned in official documentation. Meanwhile, it plays a key role in the stability of Xiaomi’s MIUI shell, and in this article, we’ll take a closer look at what MIUI Daemon is, how it interacts with other services, why it sometimes eats resources, and what to do if it starts to behave suspiciously.

Many users mistaken MIUI Daemon for a virus or unnecessary software, especially when they see it in the list of active processes with high consumption of the CPU. In fact, it is one of the main "watchdog" demons of MIUI, responsible for monitoring the integrity of the system, updating configurations and synchronizing the Android kernel with proprietary modules Xiaomi. Without it, the smartphone will either not boot or will malfunction. But then why does it sometimes behave like malware? And can it be eliminated?

What is MIUI Daemon and why is it necessary?

MIUI Daemon (or) miui_daemon In Linux-based systems, this is a background process that starts at start. MIUI It's a whole session, and it's a core function:

  • πŸ”„ System Integrity Control: Ensures that critical files are MIUI have not been damaged or changed (for example, after a failed rooting).
  • βš™οΈ Configuration Management: Applies theme, font and system settings that the user has changed through the Settings menu β†’ Topics.
  • πŸ“‘ Synchronization with Xiaomi servers: checks the relevance of firmware, updates data for Mi Cloud and other services.
  • πŸ›‘οΈ Protection against unauthorized changes: blocks attempts by third-party applications to modify system files (for example, via Magisk or Xposed).

In essence, MIUI Daemon is a bridge between the Android kernel and Xiaomi’s proprietary add-ons, and without it, many features (like Second Space, Game Turbo, or App Lock) simply won’t work, but its activity isn’t always obvious: it can only wake up under certain conditions, such as installing updates or changing theme.

It is important to understand that MIUI Daemon is not a separate application, but part of the system software. It cannot be removed by standard methods (via Settings β†’ Applications), since it is sewn into the firmware. Attempts to forcefully stop the process can lead to a bootloop ( looped reboot) or loss of functionality.

⚠️ Note: If you see the process miui_daemon in the task manager with consumption CPU more 20% It's not normal for a long time, and it could be a broken firmware, a root-rights conflict, or malware that masquerades as a system process.

How MIUI Daemon Interacts with Other System Processes

MIUI Daemon doesn't work in isolation, it's closely linked to other MIUI services.

Process/ServiceInteraction with MIUI DaemonConsequences of blocking
miui.analyticsTransmits data about the use of the smartphone to improve MIUI (if the option is enabled in Settings β†’ Additional β†’ Analytics).Loss of usage statistics, but does not affect the system.
miui.guardproviderResponsible for security and blocking suspicious activity, MIUI Daemon checks his status.App Lock, Permission Manager and other security features are disabled.
android.process.mediaSynchronizes media files and app cache. MIUI Daemon monitors its restart when crashes.Loss of miniatures in the gallery, errors in music playback.
com.xiaomi.marketUpdates data for the Mi App Store. MIUI Daemon keeps the certificates up to date.Inability to update applications through the company store.

Interaction with miui.guardprovider is especially important – if MIUI Daemon Detects has suspicious activity (for example, trying to change the file /system/build.prop), it can initiate a reboot or rollback of changes. That is why after rooting or installing custom modules, the smartphone sometimes β€œhangs” on the MI logo – this MIUI Daemon blocks unauthorized changes.

Interestingly, MIUI Daemon is less aggressive in global ROMs than in China ROMs, because China has stricter mobile security requirements and Xiaomiforced includes additional checks.

πŸ“Š Have you ever tried to modify your firmware on Xiaomi?
Yeah, I was doing custom Recovery.
Yeah, got a Root license.
No, I'm afraid to break my phone.
No, I'm good with standard functions.

Why MIUI Daemon is loading a processor or battery

Normally, the MIUI Daemon consumes less than 1-3% of the CPU and has little impact on autonomy, but sometimes users experience a process that starts to "eat" up to 30-50% of the processor or drain the battery.

  • πŸ”„ Damaged firmware: if files MIUI have been changed incorrectly (for example, after an interrupted update), MIUI Daemon is constantly trying to restore them.
  • πŸ“± Root rights conflict: If you received Root via Magisk or SuperSU but did not disable DM-Verity, the process will scan the system in a loop.
  • 🦠 Malware: Some viruses are disguised as miui_daemon, To avoid detection, check the hash process through ADB.
  • πŸ”§ Update error: if the firmware was installed with errors (for example, via Fastboot with missed steps), MIUI Daemon may be fixated on verification.

How to check that the problem is in MIUI Daemon, not another process? Open Settings β†’ The phone. β†’ Version. MIUI and click on the build number string several times to activate Developer Mode. β†’ Additionally. β†’ For developers β†’ Activity monitor and see which process consumes the most resources. miui_daemon, Get to the diagnostics.

⚠️ Some β€œoptimizers” (e.g. Greenify or Battery Doctor) offer β€œfreeze" MIUI Daemon to save battery, which will cause key functions to fail MIUI, including updates and synchronization!

πŸ’‘

If your smartphone is slowing down after the MIUI update, try resetting the cache via Recovery: turn off the device, press Power + Volume Up, select Wipe Cache Partition. This will not delete your data, but can solve the problem with the MIUI Daemon freeze.

Can I remove or disable MIUI Daemon?

The short answer is no, unless you're willing to lose the functionality of a smartphone. MIUI Daemon is part of the system kernel, and removing it is tantamount to damaging the firmware. However, there are a few partial solutions for those who want to reduce its activity:

  1. Disable Analytics: Go to Settings β†’ Additional β†’ Usage Analytics and deactivate the option. This will reduce the number of MIUI Daemon calls to Xiaomi servers.
  2. Remove unnecessary services: If you have a rooted phone, you can use Magisk or Titanium Backup to β€œfreeze” related services (e.g. miui.analytics), but not the demon itself.
  3. Switching to custom firmware: Some builds (like LineageOS or Pixel Experience) don’t use MIUI Daemon, but they lose Xiaomi’s branded features.

If you are experimenting, remember:

  • 🚨 Removal MIUI Daemon through ADB The file manager will lead to the bootloop.
  • πŸ”§ Disabling via Tasker or Automate will have a temporary effect, but the system will restore the process at the first check.
  • πŸ“± On some models (e.g. Xiaomi) 12T or Redmi Note 11) MIUI Daemon is protected. SAR (System-as-Root, which makes it almost impossible to modify.
What happens if you force the MIUI Daemon trial to be killed?
The smartphone will either reboot immediately or freeze with a black screen in 10 to 30 seconds, and in some cases (such as on the POCO F3), this can lead to a network reset or loss of IMEI. You can only restore work through flashing.

If MIUI Daemon is behaving unstablely (constantly loading the CPU, causing lags or errors), try the following steps:

Check the temperature of the processor in Settings β†’ Battery|Update. MIUI last-minute|Turn off the root rights (if any)|Reset the cache via Recovery|Do the reset to factory settings (if nothing helps)-->

1. Virus testing

Install Malwarebytes or Dr.Web and scan the system. Some viruses (like Triada or Ztorg) masquerade as system processes.

  • πŸ“ Unknown files in /system/bin/ or /system/xbin/.
  • πŸ”— Suspicious permissions for applications (e.g. access to the SU without your knowledge).
  • πŸ“‘ Unusual traffic in Settings β†’ Transfer of data β†’ Using traffic.

2. Firmware recovery

If the problem occurs after the update, try:

  1. Download the full firmware package for your model from the MIUI Downloads website.
  2. Rename the file to update.zip and put it in the root of the memory.
  3. Go to Settings β†’ About Phone β†’ System Update, click on three dots in the upper right corner and select Select a firmware file.

3. Retrace to factory settings

If nothing helps, do a hard reset:

  1. Save data (photos, contacts, SMS) to your computer or to the cloud.
  2. Go to Settings β†’ About the phone β†’ Reset settings.
  3. Choose to erase all data and confirm the action.

⚠️ Note: On models with a locked bootloader (such as the Xiaomi 13 Pro), a factory reset may require authorization to the Mi Account!

MIUI Daemon on different Xiaomi models: features

The MIUI Daemon behavior may vary depending on the smartphone model and firmware version.

Model/SeriesFeatures of MIUI DaemonTypical problems
Redmi Note 10/11More aggressive integrity check due to the popularity of models among fans of custom firmware.Conflicts with OrangeFox Recovery, hanging out when installing Magisk.
POCO F3/F4It is optimized for game scenarios, but can conflict with Game Turbo.High CPU consumption when running heavy games (e.g. Genshin Impact)
Xiaomi 12/13Integrated with HyperOS (in newer versions), less loading system.It is rare but can block Google Pay due to strict security checks.
Black SharkMinimal activity, as the firmware is closer to β€œpure” Android.There are almost no problems, except for the rare lags when upgrading via OTA.

For example, on the Redmi Note 10 Pro, users often encounter the fact that Daemon MIUI activates when connecting to a PC via MTP and begins to scan files, which leads to freezes.The solution is to use ADB to transfer files or disable media scanning in the developer settings (Disable MTP surveillance).

Nana POCO F3 Another problem: Magisk and Universal SafetyNet Fix MIUI Daemon may be fixated on checking certificates, which leads to overheating, in which case it helps to disable the Enforce DenyList option in Magisk settings.

πŸ’‘

On newer models (such as Xiaomi 14), the MIUI Daemon works in conjunction with HyperOS and less loading, but on older devices (such as the Redmi 5 Plus), it can cause lags due to outdated optimization.

MIUI Daemon and Root Rights: How to Avoid Conflict

If you've gotten Root on your Xiaomi, you've probably seen MIUI Daemon start blocking changes or triggering reboots, and this is due to the DM-Verity (Device-Mapper Verity) mechanism, which checks the integrity of the system partition to avoid problems:

  1. Turn off DM-Verity: fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img (where vbmeta.img β€” patch file for your model).
  2. Use Magisk in "DenyList" mode: Add MIUI Daemon to the exception list (Magisk β†’ Settings β†’ DenyList) so it doesn't scan modified files.
  3. Install MIUI Optimizations: This module for Magisk disables some of the MIUI Daemon checks, but may disrupt the Mi Cloud.

Important: on models with SAR (e.g. Xiaomi 12 and later), disabling DM-Verity can result in data loss or inability to update via OTA. In this case, it is better to use Custom ROM without MIUI Daemon (e.g. ArrowOS).

If after rooting the smartphone began to restart, check the logs through ADB:

adb logcat | grep -i "miui_daemon"

If there are lines in the logs with E/miui_daemon: Integrity check failed, then failed, MIUI Daemon has detected changes in the system partition and is trying to roll them back.

FAQ: Frequent questions about MIUI Daemon

❓ Why? MIUI Daemon consumes so much battery?
It could be related to: πŸ”„ Fixed configuration updates (for example, after changing the topic). πŸ“‘ Constantly checking Xiaomi servers (if the option "Saving traffic" is disabled"). 🦠 A virus masquerading as a process. Test the system with an antivirus. Solution: reset the theme settings to standard, disable analytics, and test the device for viruses.
❓ Can I turn it off? MIUI Daemon without root rights?
No, it's a system process, and you can't turn it off by standard means, and the only safe way to reduce it is to turn off unnecessary services (like analytics) in the MIUI settings.
❓ MIUI Daemon is disrupting Magisk's work?
Try: Add MIUI Daemon to DenyList in Magisk settings. Install Universal SafetyNet Fix. Disable DM-Verity (see instructions above). If nothing helps, consider switching to custom firmware without MIUI.
❓ After updating MIUI Daemon is constantly restarting the phone?
This is a typical problem with incorrect updates: πŸ“₯ Fastboot your device with a full reset (fastboot) -w). πŸ”™ Reverse to the previous version MIUI (if there's a backup). πŸ“§ Contact Xiaomi Support by providing logcat (adb logcat).
❓ Are there analogies? MIUI Daemon in other firmware?
Yes, similar "watchdog" processes are in other shells: Samsung: knox and sec_ril. Huawei: hw_daemon (into EMUI). Google Pixel: android.hardware.health@2.0-service. However, MIUI Daemon is more aggressive in terms of integrity control, which is related to the security policy of Xiaomi.
