Why Xiaomi Scale 2 Smart Scale is not connected the first time?
Xiaomi Mi Body Composition Scale 2 is one of the most popular body composition monitoring devices, but its first connection is often questionable. Unlike conventional scales, this model requires synchronization with a smartphone via Bluetooth, and the setup process depends on the firmware version, phone model and even the region of purchase. Many users are faced with the fact that the scales are not determined by the application, show a Connection error failed or do not turn on at all after unpacking.
The main problem lies in the incompatibility of application versions: from 2023, Mi Fit is gradually replaced by Zepp Life, and the old instructions on the network are no longer relevant. In addition, the scales Xiaomi Scale 2 have two modifications – global (with support for metric / imperial systems) and Chinese (metric only), which affects the connection process. In this article, we will discuss the current ways of synchronization for both versions, and also solve typical errors that interfere with the device.
If you've tried to connect scales and you get a message like Unable to find device or Bluetooth pairing failed, don't rush to return them to the store. 90% of the time, the problem is solved by resetting the settings or reinstalling the application. Next, step-by-step instructions for Android and iOS, as well as a compatibility table with different versions of smartphones.
What app will Xiaomi Scale 2 need in 2026?
Until 2022, the Xiaomi Scale 2 used the Mi Fit app exclusively to connect the scales, but after the rebranding of the Xiaomi ecosystem, this has changed.
- 📱 Zepp Life (formerly Mi Fit) is the main app for new devices, supports all weight functions, including body composition analysis and synchronization with Google Fit/Apple Health.
- 🔄 Mi Fit (older version) - still working, but not getting updates, suitable for older versions of scales (until 2021 release).
Important: If you download Mi Fit now, the system can automatically redirect you to Zepp Life. To avoid confusion, check the scale version by the serial number (under the battery compartment cover):
- 🔢 Starts with MBS05 — The global version works with Zepp Life.
- 🔢 Starts with MBS04 — Chinese version, may require Mi Fit or manual region change in settings.
If you buy a scale after 2022, install Zepp Life. For 2020-2021 devices, try both, because sometimes the old software recognizes the device better.
- 🤖 Zepp Life for Android
- 🍎 Zepp Life for iOS
- 📦 Mi Fit (APK For Android, if you need an older version.
