How to lose weight Xiaomi Mi Smart Scale 2 to factory settings: 5 proven ways

Xiaomi Mi Smart Scale 2 is one of the most popular smart weight control devices, but even they sometimes require a complete reset. The reasons can be different: sync errors with the Mi Fit application, incorrect readings after replacing the batteries, or simply a desire to transfer the gadget to a new owner. However, the zeroing of these weights is not as obvious as in classic mechanical models — there is no physical reset button, and the algorithm depends on the firmware version and how to connect.

Many users face a problem when the scales show knowingly incorrect data (for example, +20 kg to real weight) or stop syncing with the smartphone, 80% of the time it is solved by reset, but it is important to choose the right method. Some instructions on the network suggest removing the batteries for 10 minutes, but for the Mi Smart Scale 2, this only works half the time – modern firmware versions require a combined approach.

In this article, we will discuss all the current methods of zeroing, including hidden functions (for example, resetting through multiple clicks on the platform), and also explain how to avoid the typical errors that can permanently cause the scales to fail. If you have already tried standard methods without success, do not rush to throw the device away: most likely, the problem is solvable.

1.When you need to reset the scales Xiaomi Mi Smart Scale 2

Before you start zeroing out, make sure the problem does require drastic measures. Xiaomi scales can glittle for a variety of reasons, and not all of them are solved by resetting. Here are key signs that the device needs a full reset:

• 📉 The weight of the false is revealed, 0 kg at your real weight or, conversely, inflated values 10-30 kilogram).
• 🔄 The device does not sync with the Mi Fit or Zepp Life app despite the fact that Bluetooth is turned on and the scales are recognized by the smartphone.
• 🔋 After replacing the batteries, the scales stopped turning on or give an Err error on the display.
• 👤 User data in the app is lost (e.g., scales attribute your weighings to another profile).
• 🔄 Libras are constantly reset or show a flashing indicator without a result.

However, there are situations where resetting will not help or even exacerbate the problem:

• 💧 Getting moisture inside the housing (in this case, you need to repair or replace sensors).
• 🔌 Mechanical damage to the platform (cracks, dents).
• 📱 Smartphone problems (e.g., an outdated version of Mi Fit or Bluetooth 4.0 disabled)+).

⚠️ Note: If the scales show an error LO (low battery charge), but after the battery is replaced, the problem remains - first check the polarity of the battery installation.

If your situation falls under the first list, feel free to start resetting. If not, first try reconnecting the scales to the application or updating the firmware (we will talk about this at the end of the article).

Method 1: Mechanical discharge through batteries

The simplest and safest method is to completely shut down the device. 60-70% This is a step-by-step guide:

1. Turn the scales and remove the lid of the battery compartment (it is fixed on the latches - put it with a flat screwdriver or nail).
2. Get all 4 batteries of the type AAA. Pay attention to their polarity – remember or take pictures of the correct location.
3. Press the reset button (if it is in your model) and hold it. 10-15 In a second, in a Mi Smart Scale. 2 The button can be hidden under a rubber plug.
4. Leave the scales without batteries on 15-20 It takes that time for the capacitors to run out completely.
5. Install the batteries back, observing the polarity, and turn the scales on by pressing the platform.

If the scales are working correctly after that, the problem is solved. If not, move on to the next method.

⚠️ Note: Do not use metal objects (such as paper clips) to close the contacts of the battery compartment. This can damage the board.

This method is especially effective if the scales stopped turning on after a long downtime or show an Err error. If the problem is associated with synchronization, try the method below.

Method 2: Software reset via Mi Fit

If the scales are turned on but incorrectly display data or are not synchronized, you can try resetting through an app, which only works if the device at least occasionally connects to the smartphone.

Instructions for Mi Fit (relevant to versions 4.6.0 and above):

1. Open the Mi Fit app and go to Profile → My Devices section.
2. Select Xiaomi Mi Smart Scale 2 from the list of connected gadgets.
3. Slip on three dots in the upper right corner and select Remove the device.
4. Confirm the removal and wait until the process is complete (may take up to 30 seconds).
5. Close the app (curb it completely in the multitasking menu).
6. Turn on the scales by pressing the platform and wait until 0.0 appears on the display.
7. Run Mi Fit again and add scales as a new device via Add Device → Libra.

If the scales show incorrect data again after that, try an alternative method:

1. In the Mi Fit app, go to Profile → Settings → Notifications.
2. Turn off notifications for the scales, then restart the smartphone.
3. After the reboot, turn on the notifications again and try to sync the scales.

Important: If you use Zepp Life (formerly Mi Fit in some regions), the algorithm is similar, but the path to settings may differ.In Zepp Life, the reset is done via Devices → Xiaomi Mi Smart Scale 2 → Settings (cogs) → Remove the device.

💡

If the scales don’t appear in the device list in Mi Fit, try turning off Bluetooth on your smartphone for 10 seconds, then turn on again and update the device list.

Method 3: Reset by repeatedly pressing the platform

It's a hidden method that works on firmware 1.2.6 and higher, and it's useful if the scales are on but not responsive to standard reset methods.

Algorithm of action:

1. Make sure the scales are on (the display should burn 0.0).
2. Press the platform once and wait until the screen goes out.
3. Repeat the press 5 times in a row with an interval of no more than 2 seconds between touches.
4. After the fifth press, hold your foot on the platform until the symbol appears on the display. CAL (calibration) or rSt (reset).
5. Wait for the process to be completed (the scales may flash or show a running string).
6. Remove your leg and wait for the reset (about 30 seconds).

If it appears on the screen CAL, It means that the scales have gone into calibration mode:

1. Stand on the scale again and wait for a stable value (usually 50.0 kg).
2. Get off the platform - the scales will save calibration data.

This method only works on the original Xiaomi scales. On clones (such as the Xiaomi Mijia Lite), repeatedly pressing can lead to an error. E2 — In this case, use the reset via batteries.

5. Method 4: Calibration of the scales (if the reset did not help)

Sometimes the problem is not the failure of the settings, but the imbalance of the sensors, which happens after falls, replacement of batteries or prolonged downtime, in which case you need not reset, but manual calibration.

This will require a weight or an object with an exact known weight (for example, a pack of sugar 1 kg or a bottle of water 1.5 l). ≈ 1.5 kg). Algorithm:

1. Turn the scales on by pressing the platform.
2. Wait for 0.0 to appear on the display.
3. Place the weight on the center of the platform and record the readings.
4. If the weight is more than ±0.3 kg, discharge through batteries (method 1).
5. Repeat weighting. If the error remains, hardware calibration is required (see below).

For hardware calibration:

1. Remove the batteries and wait 1 minute.
2. Install the batteries back, but don't turn on the scales.
3. Press and hold the reset button (if any) for 10 seconds.
4. Without releasing the button, press the platform with one finger and hold for another 5 seconds.
5. Release both buttons – the scales should show CAL.
6. Place the weight on the platform and wait for the data to be saved (the display will blink).

If you lie after calibrating the scales, the sensors may be the problem, and then only repairing or replacing the platform will help.

⚠️ Note: Do not use objects weighing more than 150 kg to calibrate, this can damage the sensors).

6. Method 5: Firmware reset (advanced method)

If all the previous methods have failed, you have to refashion the scales, which is a last resort, because if you make a mistake, the device can finally fail, but in 90% of cases, this method restores the working capacity.

You'll need firmware.

• 💻 Windows computer 10/11 Mac.
• 🔌 USB-Type-C Cable (to connect scales to PC).
• 📁 Xiaomi Mi Smart Scale 2 (you can download it at miuirom.org or Xiaomi Firmware Updater).
• 🛠 MiFlash or Fastboot Tools.

Step-by-step:

1. Download and install MiFlash from Xiaomi’s official website.
2. Unpack the archive with firmware in a folder without Cyrillic characters (for example, C:\scale_firmware).
3. Connect the scales to the computer through a USB-Type-C cable. This may require disassembling the case (carefully tuck the latches with a screwdriver).
4. Launch MiFlash, press Select and point the path to the firmware folder.
5. Press Refresh – the list of devices should appear COM-weight-port.
6. Select Clean All mode and press Flash.
7. Wait until the process is completed (about 5-10 minutes).
8. Turn off the scales, assemble the body and check the performance.

Important: The firmware erases all the weights, including the weighing history, and may require re-binding to Mi Fit after the procedure.

💡

Firmware is an extreme method. If you're not sure about your skills, you should go to a service center. Wrong firmware can make scales a brick.

7.Typical mistakes and how to avoid them

Many users make the same mistakes when they lose weight, which leads to even more problems, and here are the most common mistakes and how to avoid them:

• 🔋 Use old batteries. If the batteries are discharged, the scales may not complete the discharge process. Always use new alkaline batteries (e.g. Duracell or Energizer).
• 📱 Mi Fit incompatible version.The app must be updated to the latest version.check this out on Google Play or App Store.
• 🌡 If the device has been in the cold for a long time (for example, on the balcony), before reset, let it heat up to room temperature (20-25°C).
• 🔄 Interrupting the calibration process if the scales show CAL, Do not turn them off until the process is complete (usually). 1-2 minute).
• 🛠 Self-disassembly without skill, if you're not sure you can gently assemble the body back, don't take any chances.

Another common mistake is using non-original chargers (if your model supports charging on the basis of the standard). USB). Xiaomi Mi Smart Scale Libra 2 powered 5V/1A. Charging with higher parameters (for example, 5V/2A) It can also disable the power controller.

If after resetting the scales still work incorrectly, check:

• 📶 Bluetooth signal stability (disable other devices that may interfere).
• 📱 Permissions for Mi Fit in smartphone settings (access to location, Bluetooth, storage).
• 🔄 Availability of firmware updates for weights (in Mi Fit go to Device Profile) → Update of the PO).
