Xiaomi fitness bracelets are some of the most popular gadgets for tracking activity, but their appearance often puts users at a loss. You hold a device with the Mi or Xiaomi logo in your hands, but how do you know if this is the Mi Band 5 or already the Smart Band 7 Pro? It is especially difficult to understand if the bracelet is bought from hand, without the original packaging or documentation.
Misunderstandings can lead to problems ranging from strap incompatibility to inability to update firmware. For example, the Mi Band 6 charger won’t work for the Smart Band 8, and in the Mi Fitness app, some features are only available for newer versions. In this article, we’ve compiled all the working ways to identify, from visual differences to hidden technical data, that will help even in the most confusing cases.
1. Visual inspection: what to look for on the case and packaging
The fastest way is to look at the bracelet and its configuration carefully, and the manufacturer labels several items, but the layout varies depending on the generation of the device.
Let's start with the bracelet body, and most Mi Bands and Smart Bands have their name engraved on the back next to the sensors.
- 🔍 Mi Band 4: “Mi Band 4” in small print under the sensor.
- 🔍 Smart Band 7 Pro: Xiaomi Smart Band 7 Pro logo under sensor SpO₂.
- 🔍 Mi Band 6: Markings can be hidden under the strap - take it off carefully.
If there's nothing on the case, check the charger (cradle). At the bottom of many docks, the model name is indicated, for example, "Mi Band 5 Charging Dock." Also, check the package - even if it's damaged, there are often fragments of the name on the side faces or stickers.
💡
If the bracelet used and marking erased, try to illuminate the body with a flashlight at an angle - engraving sometimes manifests itself in the light.
2. Design differences: how to recognize a model by appearance
Xiaomi has been gradually redesigning the bracelets, and some details help define a generation even without the inscriptions.
| Model | Shape of the hull | Button/sensor | Strap (width) | Features |
|---|---|---|---|---|
| Mi Band 1–3 | Rectangle with rounded corners | Physical button | 14 mm | Monochrome screen (Mi Band 3 has touch screen) |
| Mi Band 4 | Oval capsule | Touch button | 18 mm | Colored AMOLED-screen, removable strap |
| Smart Band 7 Pro | Rectangle with flat edges | Fully touchy. | 22 mm | Protruding sensor SpO₂, metal-frame |
| Smart Band 8 Pro | Square | Sensory + rotating crown | 22 mm | Glossy glass, NFC support |
Pay attention to the charging connector:
- ⚡ Mi Band 1-5: Two metal pins on the back.
- ⚡ Smart Band 6-8 Pro: Magnetic docking station with 4-5 contacts.
If the bracelet supports NFC, It is definitely a Mi Band 5 model. NFC, Smart Band 7 Pro or newer (except basic versions) Check for logo NFC on the body or in the settings.
3. Check through the Mi Fitness (Zepp Life) app
The official Mi Fitness app (formerly Mi Fit, now renamed Zepp Life for new models) automatically detects the bracelet model when connected.
- Download Mi Fitness (for Mi Band 1-6) or Zepp Life (for Smart Band 7/8 Pro) from Google Play or the App Store.
- Sign up or sign in to your Xiaomi account.
- Click “Add device” and select the category “Bracelet”.
- Follow the instructions for connecting via Bluetooth. After synchronization, the model will appear in the profile of the device.
If the bracelet is already connected, the model is listed under Profile → My Devices. For example, for the Smart Band 7 Pro, it will say, “Xiaomi Smart Band 7 Pro (M2129B1).” Here you can see the serial number and firmware version.
⚠️ Note: Mi Fitness does not support Smart Band 8 Pro – this model should use Zepp Life. If your bracelet is not identified, check compatibility in the official Xiaomi database.
4. Hardware methods: how to find out the model through bracelet settings
If you don't have access to the app, you can try to identify the model directly through the wristband menu, which works for devices with a screen (Mi Band 4 and later).
Instructions:
- Swipe your finger up and down the screen until you find the Settings section (the gear icon).
- Select “About the device” or “Information”.
- Scroll to "Model" or "Version" and it may be:
- 📱 The full name of the Xiaomi Smart Band 7 Pro»).
- 📱 Model code (e.g, «M2129B1» Smart Band 7 Pro).
- 📱 The firmware version (e.g., "1.16.2.14" is typical of the Mi Band 6).
If the menu doesn't have an "About" item, try the combination: press and hold the touch button for 5 seconds. On some models, this displays a service menu with technical information.
How to decrypt the code of Xiaomi model?
Search by serial number and technical data
Each Xiaomi bracelet has a unique serial number (S/N) and an IMEI (for NFC models), which can be used to identify accurately.
Where to look for serial number:
- 🔢 On the back of the body (under the strap).
- 🔢 In annex Mi Fitness/Zepp Life in the section "About the device».
- 🔢 On a box (if saved) - usually on a barcode sticker.
Next:
- Go to the Xiaomi authentication site.
- Enter the serial number in the "S/N" field.
- The system will show the model of the device and the date of production.
For models with NFC (such as Mi Band 5 NFC or Smart Band 7 Pro), you can check the IMEI through the service IMEI.info. Enter the 15-digit code and the system will determine the exact modification.
⚠️ Attention: Xiaomi bracelet serial numbers are often forged. If the site gives an error, "Invalid" S/N», Your device may not be original. Compare it to the official photos on Xiaomi's website.

6. Definition by characteristics and functions
If none of the previous methods worked, you can identify the model by its technical capabilities.
| Function | Mi Band 4 | Mi Band 6 | Smart Band 7 Pro | Smart Band 8 Pro |
|---|---|---|---|---|
| Screen. | AMOLED, 0.95" | AMOLED, 1.56" | AMOLED, 1.64" | AMOLED, 1.74" |
| SpO₂ (oxygen) | ❌ No. | ✅ Yes. | ✅ Yes (with warnings) | ✅ Yes (enhanced sensor) |
| GPS | ❌ No. | ❌ No. | ✅ Built-in | ✅ Built-in (more precisely) |
| NFC | ❌ No. | ✅ Option (NFC-version) | ✅ Yes. | ✅ Yes, with transport support) |
Additional features:
- 🎵 Music management: available starting with Mi Band 5.
- 📸 Camera Control: Smart Band 7 Pro and Newer.
- 💡 Always-On Display: Supported only in Smart Band 8 Pro.
If your bracelet can measure stress or has a sleep mode with REM phases, it is definitely a model no older than the Mi Band 6. And the presence of a voice assistant (through a microphone) indicates a Smart Band 8 Pro.
💡
The most reliable way is a combination of visual inspection + verification through the official application. If the data differs (for example, Mi Fitness shows one model and another), most likely you have a fake.
7. Frequent mistakes and how to avoid them
Many users confuse Xiaomi models because of their similarities, and here are the common misconceptions and how to avoid them:
Mistake 1: Mi Band 6 and Smart Band 7 are confused.
- 🔹 The Mi Band 6 has an oval body and a 1.56 screen, while the Smart Band 7 has a rectangular body and a 1.62 screen".
- 🔹 Smart Band 7 has magnetic charging with 5 pins, Mi Band 6 has 2 pins.
Mistake 2: All NFC bracelets are considered Smart Band 7 Pro.
- 🔹 NFC It's in the Mi Band 5. NFC, and in Mi Band 6. NFC (for the Chinese market).
- 🔹 Check the model code: XMSH15HM — This is Mi Band 6. M2129B1 — Smart Band 7 Pro.
Error 3: I don't take into account the regional versions.
- 🔹 For example, the Mi Band 5 for China has a code. XMSH10HM, global version — XMSH11HM.
- 🔹 Features may differ: in Chinese versions there is often AliPay, and in global versions there is Amazon Alexa.
If you bought the bracelet with your hands, be sure to check it for authenticity. Counterfeiting often poses as a lack of branded animation when turned on or an inability to update firmware.
