Xiaomi Report: What is it, where to find it and how to decrypt data

Have you ever encountered a situation where a Xiaomi smartphone starts to brake, overheat or suddenly discharge? Or maybe a smart light bulb Yeelight refuses to connect to the network, and a robot vacuum cleaner Mi Robot gives strange errors? In such cases, the first step to diagnosis is a Xiaomi report, which many users do not even know exists.

This hidden tool collects detailed information about the state of the device, from hardware specifications to error logs. But how to find, read and — most importantly — apply it? In this article, we will analyze all types of reports (system, diagnostic, errors), learn how to generate them on different Xiaomi devices (smartphones, TVs, smart appliances), and show how this data helps in repair, warranty service or even when selling equipment.

What is Xiaomi Report and Why You Need It?

Xiaomi Report is an automatically generated file with technical information about the device, which is created either at the request of the user or when critical errors occur.

• 📱 Hardware data: device model, serial number, firmware version, battery status, processor temperature.
• 🔧 System logs: records of recent actions (application installation, updates, crashes).
• ⚠️ Errors and warnings: fault codes, sensor data (gyroscope, accelerometer, NFC).
• 📊 Usage statistics: operating time, battery charge/discharge, load on CPU/GPU.

The main advantage of the report is that it helps:

• 🔍 Self-diagnose problems (e.g. why your smartphone turns off at 30% charge).
• 🛠️ Speed up repairs: Service centers require this data for warranty service.
• 💰 Prove a fault on return (for example, if the battery is worn out by 80% in 6 months).
• 📲 Optimize the device (finding voracious applications or background processes).

There are two types of reports:

1. Automatic – created when failures (for example, a sudden reboot or update error).
2. Manual – the user initiates the generation through hidden menus or engineering codes.

⚠️ Note: Reports contain confidential data (IMEI, MAC-Addresses, list of installed applications. Do not share them in public or with third parties!

Where to find Xiaomi report on your smartphone

On Xiaomi smartphones (including Redmi, POCO, Black Shark reports are stored in a hidden folder. Here's how to find them:

Method 1: Through a File Manager

1. Open the standard Files application (or any other file manager, such as MiXplorer).

2.Cross the path:

/sdcard/MIUI/debug_log/

3.Look for files with the.zip or.txt extension that have:

• bugreport is a complete report of the system.
• Anr is an application error ("Application Not Responding").
• Tombstone – critical failures (e.g., the fall of the kernel).

Method 2: Through the Engineering Menu (Hidden Code)

To generate a fresh report:

1. Open the Phone app and enter the combination:

##4636##

2. In the menu that opens, select Battery Information or Usage Statistics.

3. Click on the three dots in the upper right corner and select Error Report.

💡

If the engineering menu does not open, check if the Hidden Settings in the Security app are disabled. → Permits → Special access.

Method 3: Through Developer Settings

1. Activate Developer Mode: Go to Settings → About the phone and 7 times click on the version MIUI.

2. Return to Settings → Additional → For developers.

3. Find the Error Report item and click Create a Report.

How to Read Xiaomi Report: Decoding Key Data

Report files are archives with dozens of text documents, and let's look at what to look for first.

1. Section build.prop

It contains information about firmware and hardware platform.

• ro.product.model – exact model of the device (for example, Redmi Note 11 Pro) 5G).
• ro.miui.ui.version.name - shell version MIUI.
• ro.boot.hardware – platform (for example, mt6785 For Dimensity 900).

2. Section battery_info.txt

Key battery parameters:

• health: 2 — goodness, 3 — replacement.
• Capacity: current capacity vs factory capacity (e.g, 4500/5000 — wear 10%).
• temp: temperature in degrees (normal: 25–40°C).

Section dmesg.txt

Logs of the kernel system. Look for lines with:

• Thermal is a problem with overheating.
• Battery - charging errors.
• mmc - Memory failures (e.g, mmc0: error -110).

⚠️ Note: If dmesg has repeated undervoltage or overheat errors, it is a signal that the motherboard or battery is malfunctioning!

4. Section last_kmsg

It contains data on the last critical failure (if the phone is turned off or rebooted).

• Kernel panic is a fatal kernel error.
• Watchdog reset – hardware reset due to hanging.

Processor and battery temperature|Battery status (health/capacity)|Errors in dmesg (thermal, mmc)|Logs of the latest failure (last_kmsg)-->

Reports on other Xiaomi devices (TV, smart-tech)

Not only are Xiaomi smartphones able to generate diagnostic data, but let's look at how to get reports on other gadgets.

Mi TVs TV / Redmi TV

1. Go to Settings. → On TV. → Error report.

2.Click Create a report – the file will be saved in the root folder USB-The storage device (if connected).

Key data in the report:

• 📺 Panel: matrix type, number of broken pixels.
• 🔊 Audio: Tests of speakers and HDMI-ARC.
• 📶 Wi-Fi/Bluetooth: signal strength, connection errors.

Smart watches and bracelets (Mi Band, Watch)

Reports are generated through the Mi Fitness app:

1. Open the device profile → Settings → Troubleshooting report.

2. Select the problem (e.g., "Data is not synchronized") and submit a report.

The answer will be:

• 🔋 Battery status (number of charging cycles).
• 📡 Quality of communication with the phone (signal level) BLE).
• 💓 Sensor data (pulse, SpO₂) over the last 24 hours.

Robot vacuum cleaners (Mi Robot)

1.In the Mi Home app, go to the Device → Settings → Report on the problem.

2. Specify the symptom (e.g., "Not returning to base") and wait for the code to be generated.

The report includes:

• 🧹 Condition of brushes and filters (wear in the %).
• 🗺️ Maps of premises and navigation errors.
• 🔋 Battery data (work time from one charge).

💡

Xiaomi smart device reports often contain unique error codes (e.g., the codes used by Xiaomi, E12 For vacuum cleaners, it means side brush problems. These codes can be deciphered in official documentation or through support.

How to use Xiaomi Report for Repair or Warranty

The report is your main argument when you go to the service center, and here's how to file it correctly:

1. Preparation of a report for the guarantee case

Xiaomi Service Centers require:

• 📄 Report in.zip format (do not unpack!).
• 📋 Check or confirmation of purchase (to verify the warranty period).
• 📸 Photo/video problems (e.g. broken pixels on the screen).

Examples of warranty cases confirmed by the report:

• 🔋 Battery wears out by more than 20% in the first 6 months.
• 📱 Spontaneous reboots (watchdog reset codes in the last_kmsg).
• 📡 Problems with Wi-Fi/Bluetooth (Wlan: Failed to load firmware).

2. Self-repair according to the report

Some problems can be solved without service:

• 🔄 System freezes: if there are lowmemorykiller errors in dmesg, try disabling background apps or making a factory reset.
• 🔋 Quick discharge: if battery_info High voltage drop, calibrate the battery (discharge to) 0%, then charge to 100% breaklessly).
• 📡 Bad Signal: Wifi: Disconnect errors could mean antenna or router problem.

⚠️ Warning: If you have lines in the report like emmc: timeout waiting for boot or ufshcd: error, it indicates that internal memory is failing!

3. Sale of used device: what the buyer checks

When selling a smartphone or smart appliance, buyers often ask for a report to check:

• 🔋 Battery condition (wearing more than 30% - a reason for bargaining).
• 📱 Root (checked by ro.secure)=0 in build.prop).
• 🛠️ Facts of repair (for example, a replacement screen is reflected in the lsusb as a non-original display).

💡

Before selling, delete personal data from the report! Use a text editor to clean accounts and partitions installed_packages.
