How to Use Xiaomi Mi Scale 2 Smart Scale 2 Complete Guide from Customization to Data Analysis

Xiaomi Mi Scale 2 is not just a scale, but a full-fledged body composition analyzer that measures weight, fat percentage, muscle mass and even body water in seconds. But for the device to work accurately and bring real benefits, it needs to be properly set up and used. Many users face problems: scales do not sync with a smartphone, show incorrect data or suddenly turn off. In this article, we will analyze all the nuances of working with Mi Scale 2 — from the first connection to decoding indicators and eliminating typical errors.

The competitive advantage of the Mi Scale 2 is the combination of high accuracy (an error of only ± 100 g) and affordable price, but even such a simple device requires competent handling, for example, body composition measurements will be unreliable if you stand on the scale immediately after a workout or a heavy meal, we will tell you how to avoid such errors and get the most accurate data for health and figure control.

Set and specifications of Mi Scale 2

Before you use it, make sure that the Xiaomi Mi Scale 2 weigh box contains all the necessary components.

• 📦 The scales themselves (white or black)
• 🔋 4 type batteries AAA (already established)
• 📄 Short instructions in several languages (including Russian)
• 📱 QR-code for downloading the Mi Fit application

Technical characteristics of the device:

Note that the scales do not have their own screen — all the data is displayed in the Mi Fit app on the smartphone, it is both plus (compact) and minus (without a phone you will not see the results), and the device is not medical — its indicators are indicative in nature and do not replace professional diagnostics.

⚠️ Warning: If at least one item is missing or the batteries are discharged, do not use the scales before replacing the batteries.

First Connection and Configuration via Mi Fit

To start using Mi Scale 2, first install the Mi Fit app on your smartphone, which is available for free on Google Play and the App Store.

1. Sign up or sign in to an existing Xiaomi account (via Google, Facebook or phone number).
2. Click on the + icon in the upper right corner and select Add Device.
3. In the list, find the Mi Smart Scale 2 Libra and click on it.
4. Turn on Bluetooth on your phone and wait until the scales are determined.
5. Stand on the scales – they should automatically connect and display your weight in the app.

If the scales are not connected, check:

• 📱 Distance between phone and scales (must be no more than 10 meters without obstacles).
• 🔋 Battery charge (if the indicator does not flash when pressing the scales, the batteries are discharged).
• 🔄 Mi Fit version of the app (update to the latest in the app store).

Stand on the scale with bare feet-->

Once you've successfully connected, your profile will show up with your basic metrics, and you can set your weight, your height, your gender, so you can better calculate your body composition, and remember, for bioimpedance analysis, you have to stand on the scale with your bare feet, otherwise the data will be incorrect.

How to measure body weight and composition

The accuracy of the Mi Scale 2 measurements depends not only on the calibration of the device, but also on how you use it.

• ⏰ Time of day: Measure your weight in the morning, immediately after waking up and going to the toilet, but before breakfast.
• 🚿 Hygiene: Feet should be dry and clean – moisture or cream may distort bioimpedance analysis readings.
• 🏋️ Physical activity: After exercise, wait at least 2-3 hours before measurement as the body’s fluid distribution changes.
• 🍽️ Eating: Avoid measurements immediately after eating or drinking heavily - this will distort the weight and water in the body.

The measurement process itself is simple:

1. Open the Mi Fit app and make sure Bluetooth is turned on.
2. Stand on the scales with bare feet, evenly spreading the weight.
3. Wait 5-10 seconds until the results appear on the phone screen.
4. Get off the scales – the data will automatically be stored in history.

💡

If the scales show a Lo error, don't ignore it. Discharged batteries can cause sensors to malfunction, and the body composition data will be inaccurate, and replace the batteries with new ones (preferably alkaline).

In the Mi Fit app, you will see not only weight, but also parameters such as:

• Body mass index (BMI) shows the ratio of weight and height.
• Percentage of fat is the proportion of fat tissue in the body.
• Muscle mass is the weight of muscles without taking into account fat and water.
• Water level – the percentage of fluid in the body (normal – 50–60%).
• Bone mass – bone weight (important for assessing the risk of osteoporosis).

⚠️ Note: The body composition on the Mi Scale 2 may differ from professional medical tests by 5-15%. This is normal - the bioimpedance method is less accurate than, for example, DEHA scans.

Decoding indicators: what do the numbers in Mi Fit mean

Many users see dozens of digits in the Mi Fit app, but they don't understand what they mean or what values are considered normal.

For example, if your percentage of fat is above normal, but muscle mass is within acceptable limits, this may indicate a lack of physical activity, and if the water level is below 50%, you should increase your fluid intake (the norm is 30-40 ml per 1 kg of weight per day).

Mi Fit has a dynamic chart that tracks changes by day, week or month, and it's useful for analyzing the effectiveness of your diet or exercise, for example, if you're losing weight but your fat percentage isn't going down and your muscle mass is going down, that's a signal that your body is losing muscle, not fat, and then you should rethink your diet and add protein.

Typical errors and their elimination

Even with the right setup, Mi Scale 2 can fail, and let’s look at the most common problems and ways to solve them:

• 🔌 Libras not turned on: Check the batteries (they should be alkaline, not salt). Make sure the contacts of the batteries are clean (wipe them with a cotton swab dipped in alcohol). Press the scales - the connection indicator should flash.
• 📵 Out of sync with your phone: Reboot Mi Fit and turn Bluetooth on/off. Remove the scales from the list of devices in the app and reconnect. Check if the connection is blocked by third-party software (for example, "energy-saving" applications).
• ⚖️ They show the wrong weight: Put the scales on a flat, hard surface (not on the carpet!). Calibrate the scales: stand on them with a known weight (for example, a weight of 10 kg) and compare the readings. Update the firmware of the scales through Mi Fit (if an update is available).

If the scales show an Err error, it could mean:

• The maximum load is exceeded (150 kg).
• Unstable surface (libras swing).
• Sensor failure (try removing and inserting batteries back in).

⚠️ Warning: If the scales are no longer synchronized after replacing the batteries, reset them to the factory settings. To do this, press and hold the on button (also the calibration button under the platform) for 10 seconds until the indicator blinks 3 times.

💡

Most of the problems with Mi Scale 2 are solved by restarting the device (removing batteries for 30 seconds) or reconnecting in the Mi Fit app. If the error repeats, check your smartphone’s compatibility with weights (Bluetooth 4.0+ is required).

Tips for extending the life of weights

To make Xiaomi Mi Scale 2 last longer, follow the following simple recommendations:

• 🔋 Batteries: Use alkaline batteries (Duracell, Energizer) - they hold the charge longer. Avoid rechargeable batteries, as they may not provide the desired voltage.
• 🧹 Clean: Rub the platform of the scales with a soft cloth soaked in soapy solution. Do not use abrasives - they will damage the sensory electrodes.
• 🌡️ Storage conditions: Avoid direct sunlight and humidity (do not put the scales in the bathroom above the sink).°C.
• ⚡ Electrical: If the scales start to "glutch" in winter, it may be due to static electricity.

The average lifespan of the Mi Scale 2, when properly operated, is 3-5 years, but body composition sensors can lose accuracy after 2 years. If you notice that your fat or muscle mass readings have started to jump a lot for no objective reason (changes in diet or training), it may be time to think about replacing the device.

Another useful life hack: if you've been using scales for a few years and you notice that they've started lying 200 to 300 grams, you can try recalibrating them manually.

1. Take a weight with a known weight (for example, 10 kg).
2. Stand on the scale with the weights and write down the testimony.
3. Subtract weight from the total weight – if the difference is greater than 100 g, the scales require calibration.
4. Contact the Xiaomi service center or calibrate through the engineering menu (if available for your model).

Comparison with other Xiaomi smart scale models

If you haven’t bought the Mi Scale 2 yet or are thinking about replacing it, it’s helpful to compare them to the other models in the lineup.

Mi Scale 2 is a middle ground in price/quality, suitable for those who want to control not only weight but also body composition, but are not willing to pay too much for a display or extended metrics (as in Mi Body Composition Scale 2).

For those who use scales in the family, it is important to know that Mi Scale 2 supports multiplayer. In the Mi Fit application, you can create profiles for each family member, and the scales will automatically recognize who is on them (by weight and bioimpedance), but if the weight of two people is close, there may be errors in recognition, in which case you will have to manually select a profile in the application.
