WLAN Logs folder on Xiaomi: what is this folder, can it be deleted and how to do it without risk

What is the WLAN Logs folder on Xiaomi and why does it rank?

If you've ever dug into a Xiaomi smartphone's file system through a conductor or a file manager, you've noticed a hidden WLAN Logs folder in the root directory of internal memory that often weighs from a few megabytes to hundreds of megabytes, and sometimes more -- especially on devices with active Wi-Fi use. But what is this folder, why does the system need it, and most importantly, can it be safely removed to free up space?

The WLAN Logs folder is automatically created by MIUI to store Wi-Fi logs, which records network connections, authentication errors, data rates, reconnections, and other wireless network events, which help Xiaomi engineers and MIUI developers diagnose Wi-Fi problems, but are often useless to the average user.

The problem is that the system doesn't always clean those logs properly, and over time, the folder grows to take up precious space on the internal drive, especially on low-end Redmi or POCO models with a small amount of memory (32-64 GB), where every megabyte counts, but before you grab the deletion, it's important to understand which files are stored in WLAN Logs and which ones are critical to the system.

What files are stored in the WLAN Logs folder and what are they responsible for?

Inside the folder. WLAN Logs usually contain files with extensions.log,.txt,.bin or.dmp. Their names often include dates, timestamps or technical designations (for example, wifi_error_20260515.log). Let’s see what each type of file means:

• 📄 Files with the extension.log or.txt - text logs, which record events of connection to Wi-Fi (successful and unsuccessful), change of access points, errors DHCP, Data speed and other parameters: these files can be viewed in any text editor, but they are of interest to the user only if the problem is diagnosed.
• 🖥️ The.bin or.dmp files are binary Wi-Fi memory dumps that are created when critical failures occur (such as a connection break or driver error) and contain a snapshot of the module's state at the time of failure. These files take up the most space and are often of no use to the user.
• 🔄 Files with type names wifi_stats_* or wifi_debug_* — Network statistics that system services use to optimize connections, which will not disrupt Wi-Fi, but may reset some of the auto-connection settings.

It's important to understand that MIUI doesn't use these files in real time -- they're only for debugging. However, some service processes may turn to them when diagnosing problems. For example, if you complain about poor Wi-Fi to a Xiaomi service center, experts may request these logs for analysis.

Can I delete the WLAN Logs folder on Xiaomi without consequences?

The short answer is yes, but with reservations: Deleting the WLAN Logs folder will not cause immediate system failure or loss of Wi-Fi functionality.

⚠️ Note: If you notice that Wi-Fi on your Xiaomi is unstable (frequent cliffs, slow connection, authentication errors), do not delete logs immediately. They can help identify the cause of the problem.

What happens after removal:

• ✅ Free up space on the internal drive (from megabytes to 1-2 GB on some devices).
• ✅ The system will automatically restore the folder the next time you connect to Wi-Fi, but it will be empty.
• ⚠️ Small glitches with auto-connection to saved networks are possible (you will have to manually select a network 1-2 times).
• ❌ There will be no critical crashes – Wi-Fi will continue to work, but diagnosing problems will become more difficult.

If you do decide to clean a folder, do it manually — don’t use cleaners like Clean Master or CCleaner that can delete something extra, and don’t set up automatic removal through Tasker or other automatizers — it can interfere with system services.

💡

Before deleting, check the size of the WLAN Logs folder through the file manager. If it takes less than 50 MB, cleaning it will not give a noticeable increase in free space, but may cause unnecessary system events.

How to remove the WLAN Logs folder: Step-by-step instructions

To safely clean the folder, follow this instruction, which is suitable for all Xiaomi, Redmi and POCO smartphones based on MIUI 12-14 (including HyperOS).

Step 1. Open the file manager

Use the standard Files app (or any other manager with root folder access, such as Solid Explorer or FX File Manager). Go to Device or Internal Memory.

Step 2. Find the WLAN Logs folder

It is usually located in the root directory (near the DCIM, Download, and MIUI folders). If the folder is not, then the logs have not been created yet or your version of MIUI stores them elsewhere (see the table below).

Step 3. Check the contents

Open the folder and see what files are stored there. If you only see old logs (for example, from last year), you can delete them safely. If you have fresh files (today or yesterday), you better leave them - they can be useful for diagnosing current problems.

Step 4: Delete unnecessary files

Select all files inside the folder (or only those older than a month) and click Delete. You don't need to delete the WLAN Logs folder itself, the system will restore it automatically. If the file manager requests root rights, refuse - they are not required for this operation.

Step 5: Reset the device

After deleting, restart the smartphone so that the system updates the cache and recalculates the free space. Check the Wi-Fi — if the connection is error-free, then everything went well.

💡

On HyperOS devices (e.g. Xiaomi) 14 or Redmi K70) folder WLAN Logs can be called WiFiLogs and can be found in the /data/misc/wifi/. To clean it, you will need root rights or a team. ADB.

What happens if the WLAN Logs folder reappears?

MIUI automatically restores the WLAN Logs folder every time you connect to Wi-Fi. It's normal behavior, and it's pointless to fight it, because that's how network diagnostics works. But you can limit the growth of the logs so that they don't take up gigabytes of memory. Here are some working ways:

• 🔧 Turn off Wi-Fi debugging (if enabled). To do this, go to Settings → The phone. → Version. MIUI (Press 7 times to activate Developer Mode, then in Settings → Additionally. → For developers and disable the option of logging Wi-Fi.
• 📱 Use third-party cleaning applications (e.g, SD Maid), but only with exceptions to avoid deleting system files.
• 🔄 Regularly clean folder manually (once every 1-2 months) through the file manager.
• 🚫 Do not use memory “optimizers” such as Security or Cleaner – they often delete logs inefficiently and can disrupt services.

If the folder grows too fast (for example, 100+MB per week), this may indicate problems with the Wi-Fi module or drivers.

1. Check the stability of the connection to the network (frequent breaks provoke the creation of new logs).
2. Update your firmware to the latest version of MIUI/HyperOS.
3. Reset your network settings to Settings → Connections and Sharing → Reset your network settings.

⚠️ Note: On some devices (e.g. Xiaomi 13 Ultra or Redmi) K60 Pro) forced removal of logs through root or ADB This can cause a failure of the Wi-Fi management wificond service, in which case only a reboot or reset of the network will help.

Alternative ways to free up space without removing WLAN Logs

If you don’t want to take the risk of deleting Wi-Fi logs but the memory on your device is running out, try these methods:

• 🗑️ Cleaning the app cache: Go to Settings → Annexes → App management, select frequently used programs (e.g. YouTube, Telegram, Chrome) and click Clear Cache.
• 📸 Transfer photos and videos to memory card: Use the function of Storage → Transfer to SD-map in the Xiaomi gallery.
• 🎮 Removal of unused items APK: Download folder often accumulates application installation files. Delete those that you do not plan to install.
• 🔄 Resetting “Other” Files: In Settings → Warehouse → Analyze the Others section and delete temporary files.

You can also use the built-in Deep Cleanup feature in the Security app:

1. Open Security. → Cleanup.
2. Press Deep Cleanup.
3. Select System Garbage and Logs (but don’t touch the Update Cache!).
4. Confirm the cleanup.

This method will delete not only WLAN Logs, but also other unnecessary system files without affecting critical data.

Frequent errors when working with the folder WLAN Logs

Many users make mistakes when trying to clean WLAN Logs, which has unexpected consequences.

If you have problems after cleaning WLAN Logs, try the following steps:

1. Reboot your smartphone.
2. Forget all the saved Wi-Fi networks and connect again.
3. Reset your network settings to Settings → Connections → Reset network settings.
4. If nothing helps, reset to factory settings (but this is an extreme measure!).

💡

On HyperOS devices (e.g. Xiaomi 14), the WLAN Logs folder can be protected by SELinux. Trying to delete it without root will result in a Permission denied error, in which case use ADB or leave the folder alone - it is not critical.
