folder WLAN Logs on Xiaomi: purpose, security and ways to clean

Xiaomi smartphone owners sooner or later face a mysterious folder WLAN Logs are in the root directory of internal memory. It takes from a few megabytes to hundreds of gigabytes, it comes out of itself, it doesn't have an obvious interface to manage. What is this folder? Why does the system create it, but doesn't delete it automatically? And most importantly, can it be safely cleaned without disrupting Wi-Fi or MIUI?

Actually, WLAN Logs is a service directory for storing logs of wireless modules (Wi-Fi, Bluetooth, sometimes). GPS). It's created by the system. MIUI This article will help you debug network problems, but it often grows to uncontrollable size, and in this article, we will explain how the folder is connected to the smartphone, why it is not visible in the standard file manager, and what to do if it eats up precious space on the disk.

We warn you right away that not all cleaning methods are equally safe, and some actions can cause Wi-Fi malfunctions or even a device to “brick” (if you are manually interfering with system partitions), so we will take a detailed look at the official and proven methods, and explain in which cases it is better to leave the folder alone.

What is it? WLAN Logs and why you need it?

folder WLAN Logs (sometimes found as a wlan_logs or WLAN_LOGS) — It's a system directory for storing wireless module logs. It's created automatically by the operating system. MIUI (starting with 8) and is used for:

• 📡 Diagnostics of Wi-Fi problems: If the smartphone loses connection, slowly connects or “forgets” the network, the system records the details of the errors in these logs.
• 🔄 Bluetooth Debugging: Some Logs Relate to Device Interfacing, File Transfer, and Connection Stability.
• 📍 Geolocation monitoring: in rare cases, the folder may contain work data GPS or A-GPS (accelerated positioning).
• 🛠️ Data collection for service centers: when you contact Xiaomi in support, you can request these logs for malfunction analysis.

It's important to understand that the folder is not a virus or malware. It's a standard component. MIUI, It's hidden from the user in normal mode, but because of errors in the cleaning algorithms, it sometimes grows to giant sizes, and there are cases where it's not easy to do that. WLAN Logs took up more than 100GB on devices with 128GB of memory!

Why is this happening? The fact is that Xiaomi doesn't always correctly delete outdated logs, especially if:

• 🔋 The smartphone is often rebooted (for example, due to unstable software).
• 📶 There are many Wi-Fi networks (for example, when traveling).
• 🤖 Installed custom firmware or modified core.

💡

If the folder WLAN Logs appeared after the update MIUI, Try resetting the network settings in Settings → Wi-Fi → Additionally. → Network resets, which sometimes help normalize the module and stop the uncontrolled growth of the logs.

Where's the folder? WLAN Logs and how to see them?

By default, the folder is hidden from the user, but it can be found in two ways:

1. Through a root file manager (such as Root Explorer or Solid Explorer): Go to the root directory of internal memory (/storage/emulated/0/) And turn on the hidden file display: WLAN Logs (with capital letters) wlan_logs (lowercased) WLAN_LOGS (capital) MIWIFI_LOGS (on some models)

Through ADB-team

Connect your smartphone to your PC, enable USB debugging in the developer settings and execute the command:

adb shell ls /sdcard/ | grep -i wlan

This will show all folders with the mention of wlan in the title.

If the folder is not in the specified places, check the following paths (depending on the version). MIUI):

On some models (for example, Redmi Note 10 Pro or POCO F3) The folder can only appear after activation of the developer mode or connection to Wi-Fi with non-standard settings (for example, to public networks with portal authorization).

⚠️ Attention: Don't confuse WLAN Logs with a folder MIUI/debug_log — The last one contains the logs of the entire system, and cleaning it can cause malfunctions. WLAN Logs!

Can I remove it? WLAN Logs without consequences?

The short answer is yes, but with reservations, the folder is not critical to the smartphone, but deleting it can affect:

• 🔍 Diagnostic problems: without logs, Xiaomi support will not be able to analyze Wi-Fi failures.
• 🔄 Automatic network recovery: after removal, the smartphone can connect to stored networks for longer (up to 1-2 minutes).
• 📱 Functions like Wi-Fi Direct or Mi Share: Temporary failures when transferring files.

In our experience, 90% of devices clean folders without consequences, but on some models (for example, Xiaomi Mi 11 Ultra or Redmi). K40) After the deletion of the logs, it may:

• Disappear the history of connected Wi-Fi networks (you will have to enter passwords again).
• Reset the priority of networks (the smartphone will connect to the first available, not to the priority).
• Continue scanning of available networks (the list is updated longer).

Critical point: if the folder takes more than 10 GB, it must be cleared - this may indicate a software failure, which will eventually lead to system lags.

Official and safe methods of cleaning

If you decide to delete logs, follow one of the proven methods (from simple to complex):

2. Open the command line and execute: adb shell rm -rf /sdcard/WLAN\ Logs/*
3. Reset the device.

Important: Do not use the rm command -rf /sdcard/WLAN\ Logs (without a star) – this will delete the folder itself, which can lead to errors when you next create the logs.

Method 4: Through TWRP (pitcher)

If you have a custom recap:

1. Download to TWRP.
2. Select Advanced → File Manager.
3. Move to the /sdcard/ and find WLAN Logs.
4. Delete the contents of the folder (not the folder itself!).

💡

On devices with MIUI 14 (HyperOS) folder WLAN Logs can automatically recover after cleaning. That's okay, because the system creates new logs to monitor the network, so they don't take more than 100 to 200 MB.

Why does the folder appear again and how to stop it?

Many users complain that even after removal WLAN The logs folder reappears after a few days. MIUI Actively logging network activity for:

• 📊 Optimizing energy consumption (analyzing which networks are eating away at the battery).
• 🔒 Security (detection of suspicious connections).
• 📈 Use statistics (for recommendations in Mi Cloud).

To minimize folder growth, follow the following steps:

In some models (for example, POCO X3 Pro or Redmi Note 9 Pro helps disable the Wi-Fi Assistant feature»:

1. Go to Settings → Wi-Fi → More
2. Turn off the options: 🔄 Automatic connection to open networks 📡 Notifications of new networks 🔍 Scanning is always available (in location settings)

If a folder grows over 1 GB per week, it may indicate:

• 🐛 Software bug in the current version MIUI (Check for updates).
• 🤖 Custom core conflict (if you have Magisk or Xposed installed).
• 📡 Wi-Fi module problems (such as a faulty Broadcom or Qualcomm chip).

Frequent mistakes when working with WLAN Logs

Many users make critical mistakes when trying to get rid of the folder.

Changing the folder owner (chown command) is especially dangerous, which can cause the system to lose access to the logs and start creating them elsewhere, taking up even more memory.
