Eurotest for Xiaomi phones: a complete guide to checking your smartphone

If you're buying a used Xiaomi smartphone or just want to check the condition of your device, the term "eurotest" is a must-see term, not an official feature from the manufacturer, but a special diagnostic test that evaluates the performance of key components of the phone, from the display to the battery. Unlike standard tools like ##4636##, the European test provides detailed information about the hardware, which is difficult to obtain in other ways.

Why does it matter? Imagine if you buy a Redmi Note 12 with your hands, and a week later you find that it has a broken gyroscope or the battery is dead for only 2 hours, and the Eurotest helps you identify such problems before you buy, saving time and money. Moreover, some service centers require the results of this test before repairing under warranty, and in this article we will discuss how to run the Eurotest on Xiaomi, what parameters it checks, and how to correctly interpret the results - with examples for popular models like POCO X5 Mi 11.

What is a European Test and Why is it Necessary

Eurotest (or Euro Test) is an informal diagnostic menu that is activated through engineering codes or special applications, and it was created thanks to enthusiasts who developed a universal tool for checking smartphones based on Qualcomm and Mediatek – these are the chips used in most Xiaomi devices.

Unlike standard tests (e.g. ###6484## for screen checks), the European test gives a comprehensive assessment of:

• 🔋 Battery: real capacity, number of charging cycles, temperature
• 📱 Display: broken pixels, color reproduction, sensor (multi-touch)
• 🎯 Sensors: gyroscope, accelerometer, compass, proximity sensor
• 📡 Network and Communication: Signal Strength, Range Support 4G/5G, trouble SIM-card
• 🔊 Audio: speakers, microphone, 3.5 mm connector (if any)

The main advantage of the European test is that it shows hidden parameters that the manufacturer does not display in the standard menu, for example, you will find out how many times the phone has been reflashed or whether there are hardware limitations on charging (as in some models). POCO battery-change).

⚠️ Note: Eurotest is not an official Xiaomi tool; its use is at your own risk - in rare cases, incorrect commands can cause a system failure.Always back up the data before diagnosing.

How to run the Eurotest on Xiaomi: step-by-step instructions

There are two main ways to run a Eurotest: through engineering code or through a third-party application. Let's look at both.

Method 1: Through engineering code (for Qualcomm chips)

This method works on most Xiaomi models with Snapdragon processors (e.g. Redmi Note 11 Pro, POCO F4, Mi 10T). Follow the instructions:

1. Open the Phone app.
2. Enter the code ##36446337## (or alternative #3644637##).
3. If the code doesn't work, try ##4636## → Go to the Euro Test tab (if any).
4. On some firmware (e.g, MIUI 14) you may need to enter a password: 1234 or 0000.

If nothing happens after entering the code, it means:

• 📵 Your model doesn't support this method (you may have a Mediatek chip).
• 🔒 Manufacturer has blocked the engineering menu in your version MIUI.
• 🛠️ Requires unlocking the bootloader (on some custom firmware).

Method 2: Through the application MTK Engineering Mode (for Mediatek)

For smartphones on Mediatek processors (for example, Redmi) 10A, POCO M4 Pro) you will need a third-party application:

1. Download. MTK Engineering Mode from Google Play.
2. Open the application and grant superuser rights (if requested).
3. Go to the Hardware Testing section → Euro Test.
4. On some devices, you may need to select MTK Settings → Engineer Mode → Euro Test.

If the app doesn’t find the Eurotest menu, try the shortcut Master (see for actions called euro or engineering).

What parameters are checked by the Eurotest: decoding the results

Once you start the Eurotest, you'll see a list of tests that are categorized, and let's look at the most important ones and their normal values.

Battery (Battery)

This section shows the actual state of the battery, which is often hidden in standard settings.

• Battery Health: Must be Good (if Poor or Replace is worn out)
• Capacity: real capacity in mAh. For example, for Redmi Note 12 Pro with claimed 5000 mh normal — 4500–4800 If less. 4000 — battery is severely degraded.
• Charge Cycles: number of full charge cycles. 500 Cycles – Reason to Consider Replacing.
• Temperature: Normal temperature when charging — 30–40°C. If higher 45°C, check the charger.

Example: If the European test shows a capacity of 3200 mAh instead of the declared 5000, it means that the battery is worn out by 36%.

2. Display (Display)

The display test checks:

• 🎨 Color rendering: whether all colors are displayed without distortion (checked on monochromatic screensavers).
• 👆 Multi-touch: number of simultaneously recognized touches (normal - 5-10 points).
• 🔍 Broken pixels: white/black dots that don’t change color.
• 📏 Permission: must be the same as the one claimed (e.g, 2400×1080 for POCO X4 Pro).

If the multi-touch test shows fewer than 5 points, it may indicate sensor problems (e.g. after a fall or repair).

Sensors (Sensors)

Eurotest checks all sensors of the device, pay special attention to:

• 🧭 Gyroscope and accelerometer: if the phone gate values do not change or jump - the sensor is defective (relevant for games and games) AR-applications).
• 📱 Approximation Sensor: Should work when you bring your hand to the top of the screen (if not, you will have problems with calls).
• 🌡️ Light sensor: checks for automatic brightness control.

Example of problem: If the gyroscope shows zero values, games like PUBG Mobile or Genshin Impact will be unmanageable.

4. Network and Communication (Network)

This section checks:

• 📶 Signal strength: should be higher -90 dBm (if) -110 dBm is a very weak signal).
• 📡 Support for ranges: for example, for 4G Band 3, 7, 20 (for Russia) should be displayed).
• 📞 IMEI: The phone must match the box (if Null is a blacklisted phone).

If the band is not in the supported bands list 20 (800 MHz), you may have coverage issues in the outback. 4G.

What to do if the European Test is not launched

If none of these methods worked, the reasons may be as follows:

1. Blocked Engineering Menu: in the latest versions MIUI (13-14) Xiaomi restricts access to diagnostic tools, using applications like Shortcut Master or Activity Launcher.
2. Incompatible processor: on some models with Dimensity chips (e.g. Redmi) K50) Eurotest may not be supported. Alternative - Appendix CPU-Z iron-test.
3. Brush firmware: if the phone is stitched with an unofficial version MIUI Or LineageOS, the engineering codes may not work. Try to get back the stock firmware.
4. Operator restrictions: on some phones locked under the operator (e.g. Redmi for the mobile phone). Tele2), Access to the Engineering Menu is closed.

If nothing works, there are two options:

• 🔧 Contact Xiaomi for diagnostics (they use their own internal tools).
• 🛒 Buy USB-Debugger like UFi Box or Medusa Pro – they allow you to run diagnostics without restrictions.

⚠️ Warning: On phones with bootloader unlocked, some engineering codes may cause a reset. Always check backups before experimenting!

💡

If the Eurotest doesn’t start, try entering the code ##6484##, an alternative display test that works on most Xiaomi models even with the blocked engineering menu.

How to interpret results: when your phone needs repairs

The Eurotest gives you a lot of data, but not all of it is critical, and here are the key signs that something is wrong with the phone:

1. Battery.

• 🚨 Battery Health: Replace + capacity < 60% of the claimed → We need a battery replacement.
• 🔥 Temperature. > 50°C when charging → Problems with the power controller or charger.
• ⚡ Charge Cycles: 1000+ → battery on the verge of resource production.

2. Display.

• 🖥️ Broken pixels (especially in the center of the screen) → We need a matrix replacement.
• 👆 Multi-touch only works at 1-2 points. → sensory layer damaged.
• 🎨 Colors are distorted (e.g. green tint) → plume-and-matrix problems.

3. Sensors.

• 🧭 The gyroscope/accelerometer shows zeros → Faulty sensor (repair or replacement of boards is needed).
• 📱 The proximity sensor is not working. → Problems with calls (the screen will not turn off when you bring it to your ear).

4.Network.

• 📵 IMEI: Null → Blacklisted phone (possibly stolen or unpaid loan).
• 📡 There are no key bands (e.g. Band 20) → slack 4G.
• 📶 Signal's constantly on. < -100 dB → antenna or modem problems.

If you find at least one of these problems, you should not buy such a phone - repairs can cost 30-50% of its cost.

Alternatives to the Eurotest: Other ways to check Xiaomi

If the European test is not running or you want additional diagnostics, use these tools:

Standard diagnostic codes

• ##4636## → information about battery, network, use.
• ##6484## → display test (colors, sensor).
• ##0*## → pixel-check.

Third-party annexes

• 🔋 AccuBattery – shows the real battery capacity and wear.

3. Hardware diagnostics

For deep check (for example, before buying a phone from hand) you can use:

• 🔌 USB-Debuggers (UFi Box, Medusa Pro) - check IMEI, lockdown, memory status.
• 🔧 Service centers – some Xiaomi SCs conduct express diagnostics for free before buying.

If you buy a phone on an Avito or Yula, ask the seller to install the AccuBattery and send you screenshots of your battery data, which is the minimum that will protect you from cheating.

💡

Eurotest is the most reliable way to check the used Xiaomi phone, but if it does not run, a combination of standard codes and applications (AccuBattery) + Phone Doctor Plus will provide 90% of the information you need.
