Integrating health gadgets into Apple’s ecosystem is not just a trend, but a necessity for those accustomed to the convenience of iOS. Xiaomi’s smart scales have long proven to be an affordable and accurate weight control tool. However, initial synchronization with iOS devices sometimes raises questions from users because of the peculiarities of Bluetooth and Apple’s security policy. Unlike Android smartphones, where connection is often instant, the iPhone requires a number of preparatory steps for stable data transfer.
The pairing process is based on the use of official software that mediates between the “hardware” of the scales and the phone’s operating system. Bluetooth Low Energy protocol used in modern models such as the Mi Body Composition Scale 2 allows you to save battery power, but requires the correct configuration of permissions. If you just unpacked the device or changed your phone, it is important to understand that simply turning Bluetooth on in the “Control Point” may not be enough to properly work all functions. You also need to make sure that your smartphone’s operating system is updated to the current version, since older versions may contain errors in the Bluetooth drivers.
In this article, we will take a look at each setup step, look at the typical errors and how to fix them, learn how to properly register an account, what permissions are critical for background synchronization, and why sometimes data does not make it to the Health app, and also discuss the subject of calibration of the device and explain how to achieve maximum accuracy measurements at home.
Preparation for the first switch on and setup
Before you try to connect gadgets, you need to do basic training. Make sure that your Xiaomi smart scales have fresh batteries. Most often, four AAA batteries are used, although some professional models may have an integrated battery. It is critical to use new batteries from the same manufacturer, as different levels of charge can lead to incorrect readings or inability to turn on the Bluetooth module.
Remove the protective film from the bottom of the device. Many users ignore this step, forgetting that plastic insulators block the batteries from contacting the contact group. Once the insulators are removed, numbers or symbols should appear on the display to signal readiness for operation. If the screen does not catch fire, try to slightly rotate the batteries in the sockets or check the polarity of the installation.
Your iPhone also requires preparation.Open Settings and check if Bluetooth is enabled.Unlike Android, iOS doesn't scan devices continuously in the background to save power, so going to the settings menu is a must.It's also a good idea to reboot the smartphone before starting the procedure to clear the Bluetooth connection cache that may have accumulated errors from previous connection attempts.
⚠️ Warning: Do not attempt to weigh yourself during the process of adjusting or updating the firmware of the scales.Mechanical pressure on the platform can interrupt data transmission or damage the calibration sensors.
Installation and registration in the Mi Fitness application
The main management tool is the app. Mi Fit was used before, but now the company is actively transferring users to the Mi Fitness platform (formerly known as Zepp Life). Download the current version from the App Store using a search by brand name. Make sure that the developer is listed Anhui Huami Information Technology or Beijing Xiaomi Technology to avoid installing fakes.
Once installed, start the program and log in to your account. If you don't have one, you'll need to register, which is possible through a phone number or mail, which is a must, because all your data on weight, fat percentage and muscle mass are stored in the cloud and tied to this profile, and without authorization, the scales will not work, because they do not have their own storage for the history of weighings.
In the app's main menu, click on the plus or Add Device button. The system will suggest you choose the type of gadget. Find your scale model in the list. If the model is new, it can be determined automatically if the phone is next to the scales on. The search process can take from 5 to 30 seconds.
- 📱 Make sure the app has permission to use Bluetooth – this pop-up will appear when you first start up.
- 🌐 For cloud synchronization and accurate time, stable Internet access via Wi-Fi or cellular network is required.
- 🔒 Use a strong password when registering, as your personal health data is stored in your profile.
☑️ Checking before connection
The process of pairing the scales with the iPhone
When the app finds the device, a pairing request appears on the smartphone screen. Press "Plug in" or "Bind." At this point, the scale display may show a confirmation code that you need to enter in the application, or just a flashing indicator. Don't worry if the process takes longer than usual - this is a normal procedure for exchanging encryption keys.
Once the connection is successful, the app will ask you to input your anthropometric data: height, age and gender, which are necessary for calculating body composition (BMI, percentage of fat tissue, bone mass), the calculation algorithm is based on bioimpedance analysis, which passes through the body a weak electric current. Without correct input data, the calculations will have a high error.
It is important to set up a user profile correctly. If you have multiple people using the scale, create separate profiles or activate the Guest mode for one-time measurements. Xiaomi allows you to automatically recognize up to 16 users by matching the current weight with the history of previous weighings.
💡
To improve the accuracy of the user's definition, hang yourself in a minimum of clothing in the morning on an empty stomach, which will create a reference point for the recognition algorithm.
Synchronization with Apple Health (Health)
One of the main reasons Xiaomi’s weights are popular among iPhone owners is the ability to integrate with the native Health app, which allows you to see all the statistics in one place without switching between apps. To set up this feature, go to the device profile inside the Mi Fitness/Zepp Life app and find the Add Accounts or Third-Party Services section.
Select Apple Health from the list and grant all the permissions you request. iOS controls data access very tightly, so you'll need to manually turn on switches for the Weight, Body Mass Index, Fat-free, and others categories. Without those permissions, the data will come to the scale app but won't be displayed on Apple's system.
Sometimes there is a situation where the data stops updating, in which case, try to turn off the sync in the application settings and turn it on again. Also make sure that in the Health app itself, in the Data Sources section, your weights app takes precedence, or at least is allowed to be read and written. Data source conflict is a common reason why weight in Health doesn't change after squashing.--

Solving Connection Problems and Errors
Even if you follow all the instructions, you can have technical difficulties. One of the most common problems is that the scales are visible in the phone's Bluetooth list, but not connected in the app. This is because a direct connection through the iOS settings blocks the application. The Bluetooth channel must be occupied exclusively by the Mi Fitness/Zepp Life app.
If the scales are no longer defined, try to reset completely. For most Xiaomi models, this is done by removing the batteries for 10-15 seconds. Also, removing the device from the list of paired in the Bluetooth settings of the iPhone itself helps (click on the icon “i” next to the device and select “Forget the device”), then you need to re-start the search in the application.
Unstable connections can be caused by interference from other gadgets or routers running at 2.4 GHz. Try to move away from the Wi-Fi router or turn off other Bluetooth devices nearby for a while. Also check if the phone is in “Energy Saving” mode, which can limit the background activity of the application.
| Problem. | Possible cause | Decision |
|---|---|---|
| Libras not included | Battery or poor contact | Replace all 4 batteries, clean contacts |
| No connection to the phone. | Libra is occupied by another device | Disable Bluetooth on other gadgets, forget the device in iOS |
| Measurement error | Uneven floor surface | Move the scales to a firm, flat floor (not carpet) |
| No firmware updates. | Weak Wi-Fi signal | Get closer to the router, check the iOS version |
Calibration and accurate data acquisition
To ensure high accuracy, it is important to follow the rules of operation. Weighing should take place on a hard, flat surface. Soft coatings, such as carpet or soft-backed linoleum, can distort the readings of strain gauges, as part of the weight goes to deformation of the coating. It is recommended to put the scales on tile, laminate or wooden floor.
The first weigh-in after moving the scales or replacing the batteries may not be accurate. The device must undergo self-testing and calibration. Stand on the scale, wait for the switch on, then go off and wait until the display shows "0.0" or "0.00." Only then you can make a full measurement.
To track weight, weigh yourself at the same time of day, preferably in the morning after going to the toilet and before meals. Clothing also affects the result, so it is better to perform the procedure with or without clothing. Bioimpedance analysis is sensitive to hydration, so dehydration or, conversely, drinking large amounts of water before weighing can change the percentage of fat.
⚠️ Attention: People with pacemakers or other electronic implants should refrain from using the body composition analysis function.The electrical impulse, although weak, could theoretically affect the operation of medical devices.
💡
The accuracy of smart scales depends not only on the quality of sensors, but also on the stability of the surface and the correctness of personal data entering in the profile.
