How to accurately determine the version of your Xiaomi Mi Band: from model to firmware

Did you buy a used Mi Band on Avito, get a gift from relatives or just forget what model of fitness bracelet you have? Determining the version of Xiaomi Mi Band is important not only for the “checkmark” – it depends on compatibility with applications, available features and even the choice of strap. For example, charging cables Mi Band 4 and Mi Band 6 are similar in appearance, but not interchangeable, and the firmware from Mi Band 7 will not stand on Mi Band 5.

In this article, we'll look at 5 reliable ways to identify your bracelet, from visual inspection to hidden menus in the Mi Fitness app, how to tell the Mi Band 3 from the Mi Band 4 by appearance, where to look at the firmware version, and why the bracelet is sometimes defined as an "unknown model," and at the end you'll find the Mi Band's generational difference table from 2016 to 2026.

Visual inspection: how to distinguish models by external features

The quickest way is to look at the bracelet carefully, and the manufacturer leaves clues on the body, the screen, and even the charging cable.

• 🔍 Screen shape: Mi Band 1-4 has an oval display, and starting with the Mi Band 5, it is rectangular (like a smartwatch). 1S round-screen.
• 🔌 Charging cable: the Mi Band 3/4 The connector is outside the body (metal contact is visible), and the Mi Band has a connector. 5–8 — Hidden under the cover (module needs to be moved).
• 📏 Body size: Mi Band 6/7/8 on 20% If your bracelet seems "small," it's more like the Mi Band. 4 older.
• 🎨 Screen Color: Mi Band 3 and Mi Band 4 have a monochrome display (black and white), and all models with the 5th version — AMOLED (coloured).

If you have MDZ-XX-XX on the case (e.g., MDZ-46-DA), it's a factory article, and you can decipher it from the table at the end of the article, and you can also note the serial number, which is usually in small print on the back of the module (a series of numbers and letters after the words S/N).

2. via Mi Fitness (Zepp Life) app: step-by-step instructions

The official Mi Fitness app (formerly Mi Fit, now renamed Zepp Life in some regions) automatically detects the bracelet model when connected.

1. Open the Mi Fitness app and go to the Profile tab (the person icon at the bottom of the screen).
2. Click on your bracelet in the list of devices (usually it is displayed first).
3. Scroll down to the Device Information block – this will show the model (e.g. Mi Smart Band 6) and the firmware version (e.g. 1.0.6.54).

If the bracelet is not defined or displayed as a “Unknown device”, try the following:

• 🔄 Update the app to the latest version in Google Play or App Store.
• 📱 Reconnect the bracelet: go to the profile → The device → Disable, then add it again via Add the device.
• 🌐 Change region in the app settings (sometimes Chinese versions of bracelets are not recognized in the European region).

Update Mi Fitness to the latest version

Reset the bracelet (hold the button for 10 seconds)

Disable/connect the bracelet again in the application

Check the compatibility of the model with your smartphone-->

⚠️ Note: If the app displays a Mi Band 4 model but looks like the Mi Band 5, you probably have a fake. Chinese clones often disguise themselves as popular models, but have stripped down functionality.

3. Through bracelet settings: hidden menu with software version

Each Mi Band stores firmware information in the service menu, and to get there, follow the following steps (the instruction is universal for all models starting with the Mi Band 3):

1. On the main screen of the bracelet, swipe your finger up until the settings menu appears (icon) ⚙️).
2. Select About Device (on some models – Information or About).
3. Scroll down - there will be lines Model, Software version and Hardware version.

The Mi Band 7/8 is a bit different.

1. Swipe up on the main screen.
2. Select Settings → System → About the device.
3. Click on the Software Version 5 times in a row and the service menu with additional data (for example, BLE Version and Sensor Version) will open.

If the menu is in English and you need the Russian version, check the language settings in the Mi Fitness app. Sometimes after updating the firmware, the language is reset.

💡

If the bracelet does not respond to swipes, try resetting it to factory settings: go to Settings → Reset (on some models you need to press the touch button for 15 seconds).

4.By packaging and documents: where to look for the article of the model

If you still have a bracelet box, the model is indicated on a barcode sticker (usually in format). XMSHXXXXX or MIBAND X. Please also note:

• 📦 The article on the box: for example, BHR4305GL — This is Mi Band 6 (global version). The full list of items is in the table below.
• 📄 Warranty card: model is indicated in the column "Name of goods».
• 🛒 Check or invoice: if you bought in the official store, the check must contain a line with the name of the model.

Be careful with purchases on AliExpress or Avito: often sellers indicate one model in the description and send another (for example, instead of Mi Band 7, Mi Band 6 in a repainted case may come).

⚠️ Note: Forgeries are often found typos in articles (for example, MIBAND5 PRO instead MIBAND 5 NFC). Xiaomi models never have the words “Pro”, “Plus” or “Premium” in their titles – this is a sign of fake news.

5. By serial number: code decoding

The serial number (S/N) is on the back of the bracelet module and in the Mi Fitness app, which is 14-16 characters long and contains encrypted information about the model, production date and region, such as the G71A1907123456 series, which stands for:

• G71 is the model code (Mi Band 5).
• A1 is the region (A is the global version, C is China).
• 907 – date of production (2019, July).

Here is a brief transcript of the model codes in serial numbers:

If your serial number starts with LX or LY, it’s a fake – Xiaomi’s official bracelets never use such prefixes.

6. Difference table of all Mi Band models (2016–2026)

For convenience, we have collected key characteristics of all Mi Band generations in one table, and pay attention to the columns of the Article and the screen type, which will help to accurately identify your model.

Important: The Mi Band 8 was the first bracelet in the lineup to have NFC built into all default versions (previously it was an option for an extra fee).

7. Through third-party applications: alternative methods

If the official Mi Fitness app doesn't work, you can use third-party Android utilities, which often show more technical data than the native software.

• 📱 Notify & Fitness for Mi Band (paid): Shows model, firmware version and hardware revision. Supports all models starting with Mi Band 2.
• 🔍 Mi Band Tools: allows you to view hidden bracelet settings, including a version of the Bluetooth module and sensors.
• 🛠️ nRF Connect (for advanced users): scans Bluetooth devices and shows a chip model (e.g. Nordic) nRF52832 Mi Band 4).

For the use of nRF Connect:

1. Install the app from Google Play.
2. Turn on Bluetooth on your phone and start the scan.
3. Find your Mi Band (commonly called MIBAND-X) on the list.
4. Connect to it and go to the Device Information tab – here will be the Model Number bar.

⚠️ Note: Third-party apps may conflict with official Mi Fitness software. Before using them, disable autosynchronization in bracelet settings to avoid crashes.

💡

If neither method worked, chances are you have a fake.The original Mi Band is always identified through at least a serial number or an official app.
