Connecting Xiaomi scales to iPhone 11: a complete guide to solving typical problems

Why Xiaomi scales can’t see your iPhone 11 and how to fix it

Xiaomi smart scales have long been the standard for health care professionals, but their connection to the iPhone 11 sometimes turns into a puzzle. The problem lies not in the devices themselves, but in the features of Bluetooth Low Energy (BLE) on iOS and the nuances of the Mi Fit/Zepp Life application. Unlike Android, where synchronization often goes out of the box, iPhone owners have to consider the limitations of the operating system and the version of the firmware scales.

This article doesn’t just repeat the standard instructions out of the box — we’ll break down the hidden iOS settings that block the connection, explain why scales can get lost after an iPhone update, and give unique solutions for the Mi Smart Scale 2 and Mi Body Composition Scale 2 models, which Xiaomi doesn’t document. If you’ve already tried to connect and got an error called “Device not found” or “Data failed to sync” — here you’ll find the reasons and ways to fix them.

What scales Xiaomi is compatible with the iPhone 11

Not all Xiaomi smart scales work equally well with the iPhone 11. The main difference lies in the Bluetooth version and support for synchronization protocols. Here is the current list of compatible models (tested on iOS 15-17):

• 🔹 Mi Smart Scale 1 is the base model with weight measurement and IMD (body mass index). Requires manual connection via Mi Fit.
• 🔹 Mi Smart Scale 2 — added body composition analysis (muscle mass, water, bone tissue) works best with Zepp Life.
• 🔹 Mi Body Composition Scale 2 is a flagship model with 13 metrics, including viscosity fat and metabolic age. Supports automatic synchronization with Apple Health.
• 🔹 Xiaomi Smart Scale 3 is a budget version with improved accuracy. Compatible only with the Mi Fit version 5.8+.

⚠️ Warning: Xiaomi Mi Scale (first generation, 2015) is not officially supported by iOS 15 and later. Their connection is only possible through third-party applications like Health Sync, but the data will be transmitted with errors.

Preparing iPhone 11 for connection: 5 mandatory steps

Before you try to sync scales, make sure your iPhone 11 is set up correctly.Most connectivity issues arise from:

1. An outdated version of iOS or Mi Fit/Zepp Life.
2. The limitations of the Bluetooth background in charge saving settings.
3. Conflicts with other devices connected via BLE (e.g. fitness bracelets).

Update iOS to the latest version (Settings → Main → Software Update)

Remove old Mi Fit or Zepp Life versions and install fresh ones from the App Store

Turn off the charge saving mode (Settings → Battery)

Reboot your phone (hold the Side button + Volume until the slider appears)

Make sure the scales are charged (the indicator should be green when pressed)-->

Critical: If you've previously connected the scales to another phone (especially Android), you need to reset them. To do this, press the scales and hold the switch on 10 seconds until the red light flashes, which will delete all the stored data and allow you to perform a new synchronization.

💡

If the scales don't respond to the press, check the contacts of the battery. Often the problem lies in oxidized contacts (wipe them with an alcohol wipe).

Step-by-step: how to connect Xiaomi scales to the iPhone 11

The connection process varies depending on the scale model and the application used, and below is a general-purpose instruction that works for most devices. If your model doesn't sync, go to the Problem Solving section.

Step 1: Install the correct application

For Mi Smart Scale 1/2 and Xiaomi Smart Scale 3, use Mi Fit. For Mi Body Composition Scale 2, Zepp Life (formerly Amazfit) is better suited. Download the app from the App Store and register (you can use Apple ID, Google or phone number).

Step 2: Adding a device

Open the app and go to Profile → Add device → Libra. Choose your model from the list. If it is not available, select the nearest one in terms of characteristics (for example, the Mi Smart Scale 2 option will suit Smart Scale 3).

Step 3: Activate Bluetooth and synchronize

Turn on Bluetooth on your iPhone (Settings → Bluetooth) and press "Plug" in the app. The scales should squeak, and the iPhone screen will show a pairing request. Confirm it. If the request does not appear:

• 🔄 Reset the scales (click the power button 1 time).
• 📱 Close all background apps on your iPhone (double tap on Home and swipe up).
• 🔗 Turn off and turn on Bluetooth again at Control Point.

Step 4: Set up a profile

Once connected, the app will ask for your gender, age, height and weight target, which are critical to correctly calculate IMT and other metrics, and if you enter the wrong data, the weight readings will be inaccurate.

💡

For maximum accuracy, weigh at the same time of day (preferably on an empty stomach in the morning) and without clothes. The difference in weight before and after meals can reach 1-1.5 kg.

Step 5: Checking the synchronization

Stand on the scale, the data should automatically appear in the application.

1. Open the Mi Fit/Zepp Life app manually.
2. Pull the screen down to update the data.
3. Check that the scales are connected in the Devices section.

Solving Typical Connection Problems

Even with the right setup, Xiaomi’s scales may not sync with the iPhone 11, and here are the most common bugs and ways to fix them:

Problem 1: Libra is not on the list of devices

Reason: Conflict with other Bluetooth devices or outdated firmware scales.

Decision:

• 📵 Turn off all unnecessary Bluetooth devices (headphones, fitness bracelets).
• 🔄 Reset the scales (hold the 10 seconds button).
• 📲 Remove the scales from the list of conjugated devices in Settings → Bluetooth and reconnect.

Problem 2: Data is not synced with Apple Health

Reason: In iOS, the permission to share data is disabled.

Decision:

1. Open Settings → Privacy → Health → Applications → Mi Fit/Zepp Life.
2. Enable all switches in the "Data for Record" section.
3. In the Mi Fit app itself, go to Profile → Settings → Data Sync → Apple Health and activate the option.

Problem 3: Libras are connected, but show the wrong weight

Reason: Incorrect calibration or wear of sensors.

Decision:

• 🧱 Check if the scales are standing on a level surface (use level).
• 🔧 Reset the calibration: stand on the scale, then come off - they should reset the reading.
• 🔋 Replace the batteries (even if the indicator shows charge, the batteries may have discharged unevenly).

⚠️ Warning: If the Mi Body Composition Scale 2 scales show weights 2 to 3 kg more than real, the problem may be the bioimpedance sensor. Try weighing yourself barefoot - wet socks or thick soles distort the readings.

How to update the firmware of Xiaomi scales through the iPhone

Outdated firmware is one of the main reasons for the unstable work of scales. Unfortunately, Xiaomi does not always notify users of available updates.

1. Open the Mi Fit or Zepp Life app.
2. Go to the profile section → Your devices → [name of scales].
3. Click on the three dots in the upper right corner and select Update firmware.
4. If an update is available, confirm it is installed. Don't get off the scale during the process (this will interrupt the update).

Important: Update can take up to 5 minutes. If the scales "hang" during the Preparation stage, reset them (hold the 10 seconds button) and try again.

💡

If the app doesn't have a firmware update button, it means your version is up to date. To force the updates to be checked, remove the scales from the app and add them again.

Synchronize data with Apple Health and other apps

One of the key benefits of Xiaomi's weights is that it can integrate with Apple Health, Google Fit, and third-party fitness trackers, but by default, it's disabled. Here's how to set it up:

Step 1: Allowing access to iOS

Go to Settings → Privacy → Health → Data Sources → Mi Fit/Zepp Life and turn on all the switches in the Data to Record section.

• 📊 Weight
• 📈 Percentage of body fat
• 💪 Muscle mass

Step 2: Set up in Mi Fit/Zepp Life

In the annex itself:

1. Open Profile → Settings → Data Synchronization.
2. Select Apple Health and activate sync.
3. Please indicate the frequency of the update (Automatically recommended).

Step 3: Verification of data transmission

To ensure that the data is transmitted correctly:

1. Open the Health app on your iPhone.
2. Go to the Overview section → Weight.
3. Check that the latest data match the weight readings.

⚠️ Warning: If you use multiple fitness apps (like MyFitnessPal and Apple Health), there may be a data conflict. In this case, in Settings → Health → Data Sources, disable duplicate sources, leaving only Mi Fit/Zepp Life.

💡

For accurate tracking of progress, set up notifications in Mi Fit: Profile → Settings → Notifications → Weight. The app will remind you to weigh in once a week and analyze the dynamics.
