What is DiagLogger and why is it needed in Xiaomi?

DiagLogger (Diagnostic Logger) is a system application built into firmware. MIUI. Its main task is to collect and log diagnostic information about the operation of the device:

• 🔧 Debugging Errors – If the system fails, logs help Xiaomi engineers understand their cause.
• 📊 Performance Analysts – Collecting data on processor boot, memory and battery consumption.
• 🔄 Testing updates before the release of the new version MIUI Logic helps to identify critical bugs.
• 🛠️ Service – Xiaomi Authorized Centers use this data to diagnose malfunctions.

In fact, DiagLogger is the analogue of logcat in Android, but with advanced features for needs. MIUI. It runs in the background and records events in special files that are stored in protected memory areas, and it is important to understand that without these logs, some functions (such as automatically sending error reports) simply will not work.

However, users have complaints about DiagLogger for two reasons:

1. Resource consumption – on some devices, the process can take up to 5-10% of the processor in the background.
2. Suspicions of personal data collection – although Xiaomi has officially denied this, users fear that logs may contain sensitive information.

Can I remove DiagLogger from Xiaomi phone?

Technically, it is possible to remove DiagLogger, but it is associated with serious risks. MIUI, and its removal may lead to:

• ⚠️ Unstable system operation – there may be accidental reboots, freezes or errors in the interface.
• 🚫 Loss of functionality – some Xiaomi services will stop working, such as cloud backup or diagnostics through Mi Cloud.
• 🔧 Problems with updates – when installing new versions MIUI Errors may occur due to the lack of critical components.

Moreover, it is not possible to remove DiagLogger just like that – it requires root rights (unlocked bootloader and installed Magisk or SuperSU), without which the system will simply not allow you to delete the system application. ADB (Android Debug Bridge, pm uninstall command --user 0 com.xiaomi.diaglogger is likely to return the Failure error [DELETE_FAILED_INTERNAL_ERROR].

⚠️ Note: Removing system applications on Xiaomi without understanding the consequences can lead to a “brick” (complete inoperability) of the device. If you are not an experienced user, it is better to limit yourself to disabling, not removing.

If you still decide to remove, here is what you need to consider:

💡

Removing DiagLogger does not give a noticeable increase in performance, but can break critical functions MIUI. Disconnection is a safer alternative.

How to disable DiagLogger without deleting (3 working methods)

DiagLogger’s activity and behavior may vary depending on the device model and version. MIUI. For example:

• 📱 On flagships (Xiaomi) 13/14, Redmi K60) The logger is more aggressive as it collects data to optimize performance.
• 🔋 On budget models (Redmi) 10A, POCO M5) Its activity is minimal – here the priority is given to saving resources.
• 🌍 On global firmware (MIUI Global Diagnostics Collection is more often disabled by default than in Chinese versions (MIUI China).

What happens if you completely remove DiagLogger: the real consequences

Although many users successfully remove DiagLogger and do not notice problems, there is a risk of the following consequences:

• ❌ Inability to send error reports – if an application or system fails, you will not be able to send a log to Xiaomi for analysis.
• 🔄 Problems with OTA-Updates – some users report that after deleting DiagLogger, notifications of new versions stop coming MIUI.
• 📱 Glitches in service functions – for example, Mi Cloud or backup may stop working.
• 🔧 Difficulties with diagnosis in the service center - without logs, it will be more difficult for masters to determine the cause of the malfunction.

On the other hand, if you:

• 🔹 You do not use Xiaomi cloud services.
• 🔹 Don't send error reports.
• 🔹 Install firmware manually (via Fastboot or Recovery).

You probably won’t even notice the difference after you remove it.

• 🧹 Clean the cache regularly – go to Settings → Annexes → DiagLogger → Warehouse → Clear the cache.
• 🔋 Use energy saving modes – they limit the background activity of all system processes.
• 🛡️ Install custom software – firmware like LineageOS or Pixel Experience does not contain DiagLogger.

You can also try to limit Internet access to DiagLogger:

1. Go to Settings. → Annexes → DiagLogger → Mobile Data & Wi-Fi.
2. Shut down the network.

This won’t stop the collection of logs, but it will prevent them from being sent to Xiaomi’s servers.
