Xiaomi smart scales have long been the standard for health care professionals: they not only show weight, but also analyze body composition, store measurement history and sync with your smartphone. However, iPhone owners often face problems when connecting — the app does not see the device, data is not saved, or the scales suddenly turn off. In this article, we will analyze all the stages of settings with the characteristics of iOS, and also explain how to avoid typical errors.
Many people mistakenly think that it is enough to simply stand on the scales to work, but without the right synchronization with the iPhone, you will only get numbers on the screen, without analysis and history. We tested the process on Mi Body Composition Scale 2, Xiaomi Smart Scale 2 and new versions of 2023-2026, so the instruction is relevant for most devices, and we will pay special attention to the configuration of applications (Mi Fit and Zepp Life), because this depends on the stability of work.
If you've tried to plug in a scale and you've encountered an error, don't rush to return it to the store. 90 percent of the time, it's solved by resetting the scales or reinstalling the app. And for those who've just unpacked the box, we've prepared a step-by-step checklist of each step.
What Xiaomi scales are compatible with the iPhone?
Not all Xiaomi smart scales work equally well with iOS, with the main differences being in the communication protocol (Bluetooth 4.0/5.0) and supported applications. Here is the current list of compatible devices for 2026:
- 🔹 Mi Body Composition Scale 2 is the most popular model with 13 body parameters analysis.
- 🔹 Xiaomi Smart Scale 2 is a budget option with basic functions (weight, BMI, muscle mass.
- 🔹 Xiaomi Body Fat Scale 2S — Improved version with blood viscosity measurement (requires Zepp Life).
- 🔹 Mi Smart Scale (2026) – new model with support for Apple Health (synchronization of data on weight and height).
Note: Xiaomi scales do not work directly through HealthKit (except for the 2026 model); data transfer to Apple Health will require an intermediate application (Mi Fit or Zepp Life); also check that your iPhone supports Bluetooth 4.0 or later (all models starting with the iPhone 4S).
Important: Xiaomi scales are not compatible with the iPad, even if it has the Mi Fit app installed.
Preparing for the connection: what to do before setting up
Before you start synchronizing, follow a few mandatory steps that will save time and prevent common errors:
- Update the firmware of the scales (if they have already been used). To do this, turn on the scales, wait for the indicator. --.-- On the screen, then click on them once, and the current software should appear (e.g. 1.2.3).If the version is below 1.3.0, update via the app.
- Remove old apps. If you have Mi Fit and Zepp Life installed at the same time, delete one of them, because they are in conflict.
- Turn on Bluetooth and geolocation on the iPhone. Libra uses Bluetooth LE to transfer data, and geolocation is needed to determine the region (affects units of measurement).
- Charge the scales. If the indicator doesn't burn when pressed, replace the batteries (4×AAA).New scales usually come with batteries installed, but they can be discharged after long storage.
Also check that your iPhone has an up-to-date version of iOS (at least 13.0) and older versions of the system may have Bluetooth connection issues.
Step-by-step: how to connect Xiaomi scales to the iPhone
Consider the process using the Mi Fit app (similar to Zepp Life, but with slight differences in the interface).
- Install the Mi Fit app from the App Store, link: Mi Fit in the App Store. Sign up for the first launch via email, phone number or Xiaomi account.
Set up a profile
- Indicate your height, age, gender and activity level (this affects the accuracy of measurements).
- Choose the units of measurement: kg or lb (depending on the region).
- Complete sync. Wait for the message Device is connected. Now the data will automatically be stored in the application.
The advantages of Zepp Life over Mi Fit:
| Function | Mi Fit | Zepp Life |
|---|---|---|
| Synchronization with Apple Health | ❌ No. | ✅ Yes (weight, height, steps) |
| Trend analysis (graphics) | Basic | Extended (weekly/monthly reports) |
| Support for Multiple Users | Up to 16 profiles | Up to 24 profiles |
| Notifications of progress | ❌ No. | ✅ Weekly reports |
Important: If you use Zepp Life, disable Mi Fit – the simultaneous operation of two applications will lead to data conflicts.
💡
If the scales do not save your measurement history, check the resolutions for Zepp Life in the iPhone settings: Settings → Zepp Life → Bluetooth and Location should be enabled.
