Have you ever looked at the settings? → Battery → Using a battery on their Xiaomi and seeing the mysterious logd process that persists in the top of the charge or processor consumption? If so, you're not alone. This system demon has become a headache for many Redmi smartphone users, POCO and Mi, especially after the updates MIUI. But what does it actually do? Why does it sometimes eat up to 20 percent of its battery overnight? And most importantly, can it be turned off without the risk of turning the phone into a brick»?
In this article, we’ll take logd under a microscope, from technical basics to practical optimization tips, explaining why it works so hard on Xiaomi (and much less on other brands), what logs it collects, and what happens if you try to block it, and the unique data about logd’s connection to Xiaomi Cloud services and telemetry collection system, which is rarely mentioned even in profile forums.
Spoiler: you can't (and don't need to!) get rid of logd completely, but it's possible to reduce his appetite. FAQ We have collected answers to the hottest questions, including “can I delete logd through the ADB» Why does it activate after the reboot».
What is logd and why is it needed in MIUI?
LOGD (Log daemon is a system demon responsible for collecting, buffering and recording logs in the Android operating system, and it works at the kernel level and records everything from application errors to user actions. Xiaomi has a deeper integration than Android, because it’s a very simple process. MIUI actively using logs for:
- 🔄 Failure diagnostics – if the app crashes, the system sends a log to Xiaomi Cloud for analysis.
- 📊 Telemetry collections – anonymous data about the performance of the device (for example, how often the processor warms up).
- 🔒 Security – fixing suspicious activity (e.g., root access attempts).
- 🔄 Software updates – logs help determine which devices are ready for new firmware.
Other smartphones (such as Samsung or Google Pixel) have similar tasks to do with the logcat process, but it is less aggressive. MIUI-Specific features: second spaces, No Borders mode, hyper-rendering, etc. That’s why Redmi Note 12 or POCO F5 It can consume more resources than the Pixel 7.
It's important to understand that logd is not a virus or a bug, but it's a regular component of the system, but it depends on:
- 📱 Versions MIUI (in firmware based on Android 13+ logs have become bulkier).
- 🔄 Update Frequencies (if the phone checks for updates frequently, logd is more intense).
- 📲 Number of installed applications (each one can generate logs).
Why is logd loading the processor and battery on Xiaomi?
If logd consumes 10-30% of the charge or keeps the CPU cores loaded, the reasons usually lie in one of three scenarios:
1. Excessive log generation. This occurs when:
- 🔄 The system is updated (even if you don’t see the notifications, MIUI Can download packages in the background).
- 🐞 The app is constantly falling (for example, Mi Video or GetApps).
- 📡 Debugging modes are activated (for example, Settings) → The phone. → Version. MIUI press 7 times).
2. errors in the operation of the telemetry collection module. MIUI (particularly MIUI 14 for Android 13) the logd process can get stuck sending data to Xiaomi Cloud if the company’s servers are temporarily unavailable.
3. conflict with user settings. For example:
- 🔒 Disabled permissions for Google Play Services (the system tries to write logs, but can not log in).
- 📵 Using ad blockers (such as AdGuard or Blokada) that intercept logd traffic.
- 🔧 Rooted device (modified firmware can disrupt the logger).
To check what exactly causes logd activity, open Settings. → Special facilities → Logs of the system (if there is a point) or use the command to ADB:
adb shell dumpsys -t 10 com.android.server.logdIt shows the current workload of the process, and if it's more than 5 to 7 percent at rest, it's time to take action.
💡
If logd is activated at night, check your settings → Battery → Sleep schedule. Sometimes the system involves collecting logs at this time to optimize performance.
How to reduce logd load without harming the system?
You can't completely turn off logd, it's going to cause critical failures, but there are legal ways to reduce its appetite.
1.Switch off unnecessary telemetry
Go to Settings. → Memory. → Cleanup → Cleaning settings and deactivation:
- 📊 «Sending error reports (this is the main source of logs for Xiaomi Cloud).
- 🔍 «Improvement MIUI» (anonymous data on the use of the system).
On some devices (POCO F4, Redmi K50) These options are hidden. ADB:
adb shell settings put global send_action_app_error 0
adb shell settings put global bugreport_in_power_menu 02. Limit background activity
B Settings → Annexes → Application management → Threefold → Special access → Battery Optimization Select “All Apps” and for System Services (MiuiDaemon, Analytics) Set “Limit».
3. Clear the cache of the lairs
Excessive log accumulation can make logds work harder. ADB:
adb shell logcat -c
adb shell rm -rf /data/log/*⚠️
Note: Do not manually delete files through Explorer - this can violate access rights and cause crashes. ADB.
4. Update firmware
Old versions. MIUI (particularly MIUI 12.5 and below) were bugs with infinite log entry. Check the updates in Settings → The phone. → System Update. If you don't have the current firmware, consider switching to Xiaomi.eu or HyperOS (there logs are optimized better).

What happens if you completely disable logd?
In theory, you can block logd through the ADB Magisk modules, but the consequences will be critical:
- 🚨 Failure to diagnose crashes – if the application crashes, the system will not be able to record the cause.
- 🔄 Problems with updates — MIUI Use logs to check firmware compatibility.
- 📵 Failure of some features – for example, “Fast Charging” or “Game Turbo Mode” may stop working.
- 🔒 Blocking the Mi Account – if you suspect a modification of the system, Xiaomi can block the device.
If you want to experiment, the softest way is to disable only a portion of the logd functions. ADB:
adb shell pm disable-user --user 0 com.miui.analytics
adb shell pm disable-user --user 0 com.xiaomi.midropThis will reduce telemetry collection, but will not block critical logs.
⚠️
Note: On HyperOS devices (e.g. Xiaomi 14 or Redmi) K70) A complete logd disabling can result in bootloop, which is due to a new system architecture where logs are used to manage resources in real time.
How to restore logd after disconnection?
Logd Connection with Xiaomi Cloud and Telemetry
One little-known fact is that the Xiaomi logd is closely integrated with Xiaomi Cloud and Mi Analytics telemetry collection, which means that some logs are automatically sent to the company’s servers – even if you have disabled Error Reports in your settings.
Here is what data can be transmitted (according to the reverse development of firmware) MIUI 14):
| Type of data | Example | Appointment |
|---|---|---|
| Device information | Model (Redmi Note 11), version MIUI, serial | Firmware distribution statistics |
| Failure logs | Memory dump in the collapse of the Mi Browser | Bug debugging and fixing |
| Performance telemetry | Processor temperature, battery charge, FPS play | Optimization of energy consumption |
| Data on the use of functions | Frequency of “Reading Mode” or “Super Wallpaper” | Analysis of the popularity of the feature |
| Network activity | Type of connection (Wi-Fi/4G), speed | Optimization of traffic |
⚠️
Attention: B MIUI European region (MIUI EU) Telemetry collection is less aggressive than in the global or Chinese versions.If you're concerned about privacy, consider flashing it on Xiaomi.eu.
To minimize data transfer:
- Disable Mi Cloud in Settings → Accounts. → Mi Cloud.
- Block Internet access for Mi Analytics via Settings → Annexes → Application management → Mi Analytics → Mobile data/Wi-Fi.
- Use firewall applications (like NetGuard) to limit outbound traffic to logd.
LOGD On the scalp of the scalp: what is changing?
If you have installed an alternative firmware (e.g. LineageOS, Pixel Experience, or Xiaomi.eu), logd behavior will be different:
On Xiaomi.eu:
- ✅ Logs are collected, but telemetry in Xiaomi Cloud is disabled by default.
- ⚠️ Possible bugs with log recording when using functions MIUI (For example, “Second spaces»).
Nana AOSP-Firmware (LineageOS, Pixel Experience):
- ✅ Logd runs in standard Android mode (like Google Pixel).
- ❌ Absent. MIUI-specific modules, so the resource consumption is lower.
- ⚠️ Some features (such as Game Turbo) may not work due to lack of logs.
On the firmware with Magisk/ROOT:
- ✅ You can flexibly configure logd via modules (e.g. Disable Loggers).
- ❌ Risk of disrupting the stability of the system with incorrect edits.
If logd still loads the system after flashing, check:
- Does the firmware conflict with the core (for example, MIUI-core AOSP).
- Are there any Magisk modules that modify logs (e.g. XPrivacyLua) installed?
- Is the debugging mode activated (Settings) → System system → For developers → Debugging by USB).
💡
On custom firmware without MIUI (For example, LineageOS) logd resource consumption is usually reduced by 30-50%, as there are no proprietary telemetry collection modules.
