With modern technology, you can turn a conventional weighing process into a full-fledged analysis of your body, and the Xiaomi Mi Body Composition Scale 2 is one of the leaders in this segment. This device not only shows your weight, but also calculates body mass index, percentage of fat tissue, muscle mass and other important parameters thanks to bioimpedance analysis technology. You don't have to be an engineer to start working with, you just follow the simple steps to get the gadget to start transmit accurate data to your smartphone.
The first thing you need to do after you remove the device from the box is to activate it. On the bottom panel is a battery compartment that's covered with a magnetic lid. Inside, you'll see a protective film on the battery contacts that you have to remove before you install it, and when you turn it on, the symbols will light up, which indicates that the device is ready for initial calibration and pairing.
It's important to understand that getting the most out of a gadget requires a stable connection to a smartphone. The companion app collects all the statistics, plots changes and allows you to track progress in real time. Without synchronization with a mobile device, the functionality of the scales is limited to only the basic display of weight on the built-in screen.
Preparation for first use and installation of batteries
The quality of the smart scales depends on the power source. The device is powered by four standard AAA batteries that come with the kit, but for long-term service, it is better to immediately replace them with high-quality alkaline counterparts. Low charge can lead to measurement errors or unstable operation of the Bluetooth module, which is critical for data transfer.
Install the batteries in the appropriate compartments, observing the polarity indicated at the bottom of the case. Once turned on, the device will automatically go to standby. If the display display displays a flashing symbol of the battery, replace the batteries immediately, as in this case, the analysis of body composition may be incorrect.
💡
Use only new batteries from one manufacturer and do not mix old and new cells to avoid leaks and power surges.
The surface you put the scales on is critical to the accuracy of the measurements. Pressure sensors located in the legs should be evenly in contact with the floor. The ideal option would be a hard, flat coating, such as tile, laminate or linoleum. Carpet coatings, even with a short pile, can distort readings, because they absorb pressure.
⚠️ Warning: Never use scales on soft surfaces such as carpet or thick carpets, as this will result in a significant measurement error and can damage sensors.
Before the first weighing, allow the device to lie in the room for about 30 minutes if it was brought from the cold. A sharp temperature drop can cause condensation inside the enclosure or temporary instability of electronics, this is especially true in winter, when the equipment is delivered by courier services.
Installation of the application and pairing with a smartphone
The main tool for managing and analyzing data is the mobile application. At the moment, the Xiaomi ecosystem uses the Zepp Life application (formerly known as Mi Fit) for most of its trackers and weights. Although there are many third-party utilities, the official client provides the most complete compatibility and regular updates to the algorithms.
The adjustment process is as follows:
- 📱 Download and install the Zepp Life app from Google Play or App Store.
- 🔑 Sign up with your Mi Account or social network profile.
- 🔍 Click on the profile icon in the bottom menu and select “Add device».
- ⚖️ In the list of available devices, find the “Mi Body Composition Scale 2” and click on it.
Once you have selected the device, the app will ask you to stand on the scale with your bare feet, which is necessary for the gadget to transfer its unique identifier to the phone and confirm the active connection, at which point a request for permission to use Bluetooth and geolocation will appear on the smartphone screen - both permissions are required for operation.
☑️ Connection check
If the scales aren't detected, try restarting Bluetooth on your smartphone or taking out and pasting the batteries back in. Sometimes removing the old device from the list of paired devices in the phone settings helps. Make sure you're close enough to the weights during pairing.
How to properly measure the body
To get reliable data on fat percentage and other indicators, you need to follow a certain weighing technique. Electric current that is passed through the body to analyze tissue resistance best passes through moist skin. Dry calluses or coarse skin on the feet can increase resistance and distort the results.
Stand on the platform with your bare feet, spreading the weight evenly between both feet. The feet should completely cover the electrodes that are usually located in the front of the platform. Do not move or talk during the measurement, as muscle movement can interfere with the signal.
| Parameter | Optimal time. | Conditions |
|---|---|---|
| Weighing | Fast morning | After the toilet, before the meal. |
| Clothes | Minimum | Barefoot, in light clothes. |
| Physical activity | Before training. | Or 2 hours after that. |
| Fluid intake | Before drinking. | Avoid dehydration |
It is best to take measurements at the same time of day, preferably in the morning after waking up and going to the toilet, but before breakfast, during which time the body is in the most stable state, the level of hydration is predictable, and the contents of the intestines are minimal, which allows you to track the dynamics of changes without the influence of random factors.
Why do the numbers change throughout the day?
Indicators decoding and data analysis
After weighing, the app forms a detailed report: the main indicator is weight, but for fitness and health, the percentage of fat tissue is more important. For men, the range is 10-20%, for women, 18-28%, but these values can vary depending on age and body type.
Muscle mass shows the total weight of skeletal muscle in the body, and increasing this weight at a stable weight indicates a qualitative transformation of the body and an increase in metabolism. Basal metabolism (BMR) indicates the number of calories your body burns at rest to maintain vital activity.
The app also shows visceral fat rating, which is a measure of the fat surrounding the internal organs, high levels of visceral fat are more dangerous than subcutaneous fat, as it is directly related to the risk of cardiovascular disease and diabetes, and make sure that this indicator remains within normal limits (usually up to 9-10 units).
⚠️ Note: Bioimpedance measurements may not be accurate for people with pacemakers, pregnant women, and young children, and in such cases, use scales only to control body weight.
For professional athletes or people with very developed muscles, standard formulas may indicate overweight or obesity, as muscles are heavier than fat. In such cases, focus on visual reflection in the mirror and measurements with centimeter tape, not just the numbers in the application.
Set up profiles for the whole family
One of the key features of Xiaomi Scale 2 is the ability to recognize up to 16 different users, which is implemented through the app: each family member must install Zepp Life on their phone and link the scales to their account. When weighed, the device automatically identifies the user based on weight and BMI range.
To make the guest mode or the non-account mode work properly, the scales use a weight distribution algorithm. If you weighed yourself and the data is in the wrong profile, you can manually reassign the entry in the application history, the system will remember your parameters and recognize correctly next time.
If the weight of the users is very different (for example, an adult and a child), recognition problems usually do not arise, but if the weights are close, the system may be mistaken, in which case it is recommended to take measurements sequentially and check the synchronization immediately after weighing.
Troubleshooting and calibration
Sometimes users are faced with a situation where the scales show an error or not turn on. The most common reason is saturated batteries or oxidation of contacts. Wipe the contacts with a cotton swab dipped in alcohol and install new batteries. Also check if the protective film is removed from the bottom.
If the scales are 0.00 and are not responsive to weight, recalibration may be required. Just turn them on a hard surface without connecting to your phone. If the problem persists, try resetting to factory settings via the app menu or removing the device from the Bluetooth list and adding again.
An unstable Bluetooth connection is often caused by other apps intercepting the signal. Close background programs, make sure the Zepp Life app has all the necessary permissions in Android/iOS settings. Android often requires allowing background and access to the Always location.
💡
90% of Xiaomi weight problems are solved by replacing batteries with high-quality analogues and re-binding the device in the application.
