LOGD on Xiaomi: what it is, why loads the processor and how to deal with it

Introduction: The Mysterious LOGD Process and Its Impact on Xiaomi

Have you ever looked into your Xiaomi Task Manager and seen the strange LOGD process that is obstinately consuming CPU time or RAM? This system component often raises questions among users — especially when the smartphone starts to slow down, warm up or discharge quickly. Unlike the usual applications like Mi Browser or Google Play Services, LOGD does not have an icon, it can not be simply closed or deleted. So what is it really?

LOGD (Log Daemon is an Android background service that collects and processes system logs and works on all Android devices, but on Xiaomi smartphones (especially shell-based ones). MIUI) It may be more active because of the additional diagnostic modules, and in this article we'll look at why. LOGD sometimes eats up to 20-30% CPU, How to distinguish its normal operation from failures, and what to do if it caused lags.

Spoiler: 90% of the time, high loads from LOGD are not due to viruses or breakdowns, but to automatically collect debugging information after MIUI updates or new applications are installed, but there are exceptions, and we'll talk about them.

What is a LOGD and why is it needed in MIUI?

LOGD is a part of Android’s low-level infrastructure that is responsible for:

• 📝 Collecting system logs (event logs) from the OS kernel, drivers and applications.
• 🔍 Filtering and storing mission-critical data for debugging (e.g., application errors or hardware failures).
• 📊 Transferring logs to diagnostic services (e.g. Mi Analytics or Google Play Console).
• 🛠️ Simplifying Diagnostics for Xiaomi Engineers in Bug Analysis.

On pure Android (like the Pixel), LOGD works almost unnoticed, but MIUI adds its own modules to it:

• 📱 MiLog is Xiaomi’s proprietary logging system that collects data about shell operation.

That’s why Redmi, POCO, or Mi LOGD can consume more resources than other smartphones, and that’s not always a mistake — that’s sometimes how automatic diagnostics work after installing updates.

Reasons for the high load of LOGD on Xiaomi

If the LOGD is constantly loading the processor (over 10% for an hour) or takes up hundreds of megabytes of RAM, the reasons may be as follows:

The most common reason is the background logs sent to Xiaomi after a firmware update, for example, after installing a new version of MIUI 14 or HyperOS, the system can collect compatibility data for up to a day, in which case the LOGD will consume up to 15-20% of the CPU, but then its activity will decrease.

⚠️ Attention: If LOGD It loads the processor continuously for more than 48 hours and the smartphone is very warm, this may indicate damage to system files.

How to check the activity of LOGD on Xiaomi

To determine if LOGD is really to blame for the brakes, follow the following steps:

1. Open Task Manager: Press Settings → Applications → Task Manager (or use a swipe up gesture with a delay on the home screen). Find the logd or logger process in the list.
2. Check resource consumption: If LOGD uses >10% CPU or >300MB of RAM for longer than an hour, it is not normal.
3. Use ADB for detailed diagnosis: Connect your smartphone to your PC and execute the command: adb shell top -n 1 | grep logd If the output shows a high value of %CPU or VSS (virtual memory) - the problem is confirmed.

For advanced users, it's useful to learn the logs themselves, and you can do this through ADB or applications like Logcat Extreme (requires root), and look for recurring errors in the logs with E/ (Error) or W/ (Warning).

Can I disable or remove LOGD on Xiaomi?

The short answer is that you can't completely shut down LOGD, which is a critical system process, but you can limit its activity in a number of ways.

Here's what really works:

• ⚙️ Disable sending diagnosis: Go to Settings → The phone. → Reviews and analytics and deactivate all options.
• 📵 Limit background activity: C Settings → Battery → Select "Energy Saving" Battery Mode - This will reduce the activity of system processes.
• 🔧 Remove unnecessary modules MIUI (requires root: through Magisk or TWRP You can delete packets like com.miui.analytics, but it's risky!

⚠️ Attention: If you delete LOGD It's a process that's responsible for initializing logging in the early stages of booting the OS. The best you can do is freeze it through Titanium Backup, but it's going to cause a disruption. MIUI.

For most users, the best solution is to wait until LOGD completes log collection (usually 12-24 hours), or to perform a cache reset via recovery:

1. Turn off your smartphone.
2. Press Volume Up + Power to Enter Recovery.
3. Select Wipe → Wipe Cache.
4. Reset the device.

💡

If LOGD is activated after a particular application (like Facebook or TikTok) is installed, try turning off background activity for it in the battery settings.

LOGD and security: Could it be a virus?

The logd process itself is part of Android, not malware.

• 🦠 Process substitution: some viruses masquerade as system services (e.g. logd, mediaserver).
• 📡 Data breach: if LOGD Sends logs to suspicious servers (not.mi.com or.google.com), this is a warning sign.
• 🔓 Root access: malware with superuser rights can modify LOGD personal data collection.

How to check if the LOGD has been replaced?

1. Install NetGuard or PCAPdroid and see where the logd process sends data.
2. Check the hash of /system/bin/logd file via ADB: adb shell md5sum /system/bin/logd Compare it to the reference file for your version of MIUI (can be found on the XDA Developers forums).
3. Run your smartphone in Safe Mode (press the power button → Safe Mode) If the LOGD is still loading the system, it is a systemic problem, not a virus.

If you suspect a virus but antiviruses (Dr.Web, Kaspersky) don’t find anything, try scanning your smartphone via PC using Malwarebytes or Avast Mobile Security.

💡

LOGD is not a virus in itself, but its abnormal activity can be a symptom of infection. Always check the network activity of the process through specialized applications.

LOGD on different Xiaomi models: are there differences?

The LOGD's activity may vary depending on the model and firmware version, and this is what's common across the different lines:

On POCO and Xiaomi’s flagship (e.g. 13 Pro or 14 Ultra), LOGD is often activated when:

• 🎮 Running high-demand games (collecting logs to optimize performance).
• 📸 Using the camera in Pro mode or 8K video.
• 🔄 Updates through MIUI Updater.

On budget models (Redmi 10A, POCO M4), the LOGD can cause brakes even during normal operation due to limited resources.

What do you do if nothing helps?

If you’ve tried all the ways, but LOGD still loads the system, there are some radical measures left:

1. Factory reset: This will delete all data, but also reset the logging settings. Important: before reset, disable your Mi Account, otherwise the Mi Cloud Lock may work.
2. Fastboot flashing: If the reset didn't help, swipe your smartphone with the official firmware through the Mi Flash Tool. Download the firmware for your model from the Xiaomi Firmware website. ⚠️ Note: When flashing through Fastboot, all data will be deleted, including files in internal memory. There is also a risk of “bricking” the device if you choose the wrong version of the firmware!
3. Reverse to the old version of MIUI: If problems started after the update (for example, on HyperOS), you can return the previous version. To do this: Download the archive with the desired firmware (for example, MIUI 13). Go to Settings → About Phone → MIUI version and tap 10 times on the logo to unlock Hidden Menu. Select Choose update package and specify the downloaded file.

If even the flashing hasn’t solved the problem, it may indicate:

• 🔋 Iron problems (for example, damaged flash memory).
• 🔌 Malfunction of the motherboard (especially after falls or moisture hits).

In such cases, you can only contact the Xiaomi service center.

💡

Factory reset solves 80% of software problems with LOGD. If it didn’t work, it’s probably due to hardware malfunctions or damaged memory partitions.
