Xiaomi’s logd process: what it is, why it hangs in the processes and how to be with it

If you’ve ever looked into the task manager of your Xiaomi smartphone (or other Android device), you’ve probably noticed a strange process called logd. 10-15% It's a processor load, it's always hanging in the background, it's even suspiciously consuming the battery. What is it, a virus? Xiaomi spyware? Or a critical system component that you can't touch?

In fact, logd is the standard Android system process, responsible for collecting and processing logs of all applications and the OS itself. It works on all Android devices, not only Xiaomi, but the latter have their own nuances.

• 📱 Features of the work of logd on firmware MIUI hyperos
• ⚙️ Can it be turned off (and what will happen if you do it)

Spoiler: 90 percent of the time, high logd activity isn't a bug, it's a feature of Android, but sometimes it signals deeper problems. Let's get this straight.

What is the logd process and why is it needed in Android?

The logd process (full name: logd or logd) /system/bin/logd) — This is a demon (background service) that:

• 📜 Collects logs from all applications and system components into a single buffer (logbuffer).
• 🔄 Manages rotating logs (deleting old records when the buffer is overflowing).
• 🔌 Provides access to logs through logcat, dmesg and other debugging tools.
• 🛡️ Controls log access rights (e.g., regular applications cannot read system logs).

Without logd, developers would not be able to debug applications and users would not be able to diagnose crashes, for example, when an application crashes, the logs leave a record of the cause of the crash, the same goes for system errors, hardware problems or drivers.

On Xiaomi (as on other Android devices), logd starts automatically when you boot the system and works in the background constantly% CPU And it's got minimal RAM, but sometimes it's up to 10 to 30 percent, and that raises questions.

Why logd loads processor by 10-30%: the main reasons

The high load of logd is almost always associated with active logging, and here are the most common reasons:

The most common reason on Xiaomi is the enabled debugging. USB. Many users activate it once (for example, to unlock the bootloader or install it). TWRP), And then they forget to turn it off, and in this case, the logd is running in a high-speed mode, waiting for debugging commands, and it can consume up to 15-20 hours% CPU.

⚠️ Note: If the logd loads the processor constantly (even after restarting and without connecting to the PC), this may indicate damage to system files or firmware conflict.

Another nuance: on Xiaomi with firmware MIUI (Especially on older versions, logd can be activated when using widget design or work themes, because the system actively logs interface changes.

Features of logd on Xiaomi: MIUI vs HyperOS

Firmware MIUI And HyperOS, the new shell from Xiaomi, interacts with logd in different ways:

• 📱 MIUI (before version 14: logd is often activated when you change themes or customize widgets (MIUI 10-12) could freeze when the log buffer overflows. CPU when working with a gallery or camera.
• 🚀 HyperOS (MIUI 14+): Optimized logging mechanism – logd less likely to load the system, added logging restrictions for third-party applications. In some builds, logd may conflict with Google services (for example, when synchronizing an account).

HyperOS logd is more intelligent: it dynamically adjusts logging levels depending on the system load, for example, if the phone is drained to 10%, the process automatically reduces activity to save battery. POCO series) it may incorrectly process logs from gaming applications, which leads to lags.

If you have Xiaomi on HyperOS and logd is suspicious, try:

1. Update the firmware to the latest version (via Settings → System Update).
2. Clear the system cache (Settings → Memory → Cleaning).
3. Disable unnecessary Google services (if you don’t use them).

Can I turn off logd and what happens if I do?

You can technically turn off logd, but it's not recommended, and this is what happens if you force it to stop.

• ❌ Applications will start to fly out without error logs (it will be impossible to understand the reason).
• ❌ The system will stop recording critical events (such as kernel or driver errors).
• ❌ Certain functions MIUI/HyperOS will stop working (e.g., error reports or network diagnostics).
• ❌ The phone may go to bootloop (cyclic reboot) the next update.

But there are legitimate ways to reduce the load on the logd without turning it off completely, and that's what we'll talk about in the next section.

⚠️ Note: On some custom firmware (such as LineageOS or Pixel Experience), logd can be disabled via Magisk or ADB, stock-stock MIUI/HyperOS It's going to make the system unstable.

If you want to experiment, you can limit the level of logging through the ADB:

adb shell setprop log.tag.<TAG_NAME> VERBOSE|DEBUG|INFO|WARN|ERROR|SILENT

But without knowing the specific tags (<TAG_NAME>) It's useless. It's much more efficient to use the methods in the next section.

How to reduce logd load without risk to the system

If logd is constantly loading the processor, try these safe methods:

Disable debugging by USB|Remove suspicious applications|Clear the system cache|Update firmware|Reset the network settings-->

1. Disable debugging by USB

This is the most common cause of high loads.

1. Go to Settings. → The phone.
2. Tap 7 times on the MIUI version to activate Developer Mode.
3. Back to Settings → Additionally. → For developers.
4. Turn off the debugging. USB.

2. Clean logs manually

You can drop the log buffer through ADB:

adb shell logcat -c


adb shell dmesg -c

This will temporarily reduce the load, but will not solve the problem completely if the cause is different.

3. Check for viruses

Some malware actively writes logs to mask its activities. Use Malwarebytes or a built-in scanner MIUI Security:

1. Open Security. → Scanner.
2. Run a deep check.
3. Delete any threats you find.

4. Reset network settings

Sometimes logd will load the system due to problems with the mobile network or Wi-Fi.

1. Go to Settings. → SIM-maps and mobile networks → Resetting network settings.
2. Confirm the action.
3. Reboot the phone.

💡

If logd is activated when a particular application (such as a game or messenger) is launched, try clearing its cache: → Annexes → [Title of the annex] → Memory. → Clear the cache.

5. Update firmware

Old versions. MIUI (particularly MIUI 10-12) were logd bugs that were fixed in new builds:

Settings → System Update → Check for updates.

If nothing works, the radical method is to reset to factory settings, but back up the data before you do that!

What to do if logd hangs in processes after reset

If you reset your phone to factory settings and the logd still loads the system, the problem may be:

• 🔧 Damaged firmware (for example, after a failed update).
• 🔋 Iron malfunctions (most commonly memory problems with eMMCs or UFS).
• 📦 Conflict with custom recavéri (if installed) TWRP).

In such cases, only flashing through Fastboot will help.

1. Download the official firmware for your model from the Xiaomi website.
2. Unpack the archive and launch the script flash_all.bat (for Windows or flash_all.sh (for Linux/Mac).
3. Connect your phone in Fastboot mode (clip Volume Down + Power when the phone is off).
4. Wait for the firmware to be completed.

⚠️ Note: If logd still loads the system by 20%+, This may indicate a hardware malfunction (e.g., wear of flash memory), in which case only a service center will help.

On some models (for example, Redmi Note 10 Pro or POCO X3 Pro) High load from logd after reset is associated with activation of Google services:

• Disable Google account sync (Settings) → Accounts. → Google → Synchronization).
• Remove updates for Google Play Services (Settings) → Annexes → Google Play Services → Remove updates).

Alternative ways to diagnose logd problems

If standard methods do not help, you can use advanced tools to analyze:

For example, if you see a logcat, you will see many lines like:

E/AndroidRuntime: FATAL EXCEPTION: main


Process: com.example.app, PID: 12345




java.lang.NullPointerException: Attempt to invoke virtual method on a null object reference

This means that an application (com.example.app) is constantly falling and makes logd record errors.

For Xiaomi, it’s also helpful to check logs through the BugReport built-in app:

1. Open Settings → About the phone → All the parameters.
2. Slip 5 times on the Core (or Assembly Number).
3. Choose to create an error report.
4. Wait for the log generation and send them for analysis (or study yourself).

💡

If there are many errors in the logs, E/StorageManager or E/MediaProvider, The problem could be a damaged memory of the device, requiring a diagnosis at a service center.
