How to properly reboot Xiaomi scales: all the ways and nuances

Xiaomi’s smart scales are a popular solution for controlling weight and body composition, but even such a technique sometimes requires rebooting. Problems can manifest in many ways, from connecting errors to the Mi Fit app to incorrect readings or a complete lack of reaction to pressing. In most cases, resetting or simply restarting the device helps to return to work without going to the service center.

In this article, we will discuss all the current ways to reboot for different Xiaomi scale models, from the classic Mi Body Composition Scale 2 to the new Smart Scale 3. You will learn how to perform a soft reset (without loss of data), hard reboot (with a return to factory settings), and what to do if the scales do not respond to buttons, and we will also consider typical user errors and give recommendations for preventing failures.

Important: The reboot procedure may vary depending on the firmware version and device model. If your scales are released before 2020, some methods may not work, in which case you will need to update the software through the Mi Fit application.

When do you need to reset Xiaomi scales?

Rebooting or resetting Xiaomi’s weights is required in several cases:

• 🔄 Libras do not turn on or respond to touch (no response when pressed).
• 📱 Cannot connect to the Mi Fit application (synchronization errors, permanent connection breaks).
• ⚠️ Indications of weight or body composition are clearly incorrect (for example, the weight is "frozen" on one value or displayed with a large margin of error).
• 🔋 The battery is discharged to zero, and after charging the device does not work.
• 📲 After updating the firmware appeared glitches in the interface.

In most cases, a soft reboot is the equivalent of a smartphone restart, where all the temporary data is reset, but the settings are saved. If the problem is more serious (for example, the scales do not respond to a reset through a button), you will need a hard reset - return to factory settings with the loss of all the stored data.

⚠️ Note: If Xiaomi scales show an Err or Lo error (low battery charge), try replacing the batteries first.Rebooting in this case may not help, since the device is physically unable to save the settings.

Before proceeding with a reset, make sure the problem is not related to:

• 📵 No phone connection (check Bluetooth and permissions in Mi Fit).
• 🔋 Discharged batteries (even if the indicator shows charge, try replacing the cells).
• 📱 Older version of the app (update Mi Fit or Zepp Life in the app store).

Soft reboot methods (without data loss)

Soft reboot is the safest method that doesn’t affect the user’s saved settings and profile, and it’s worth trying first if Xiaomi scales are starting to glitch but are still responsive to taps.

Method 1: Reboot via the power button

Most Xiaomi models (including the Mi Body Composition Scale 2 and Smart Scale 2) feature a mechanical button under the glass panel.

1. Make sure the scales are off (the screen is out).
2. Press and hold the button in the center of the platform for 10-15 seconds.
3. Release the button when the Mi logo or 0.0 appears on the screen.

If the screen doesn’t catch fire, try repeating the procedure by replacing the batteries beforehand. In some cases, short-term pressing (1-2 seconds) helps, but this depends on the firmware version.

Method 2: Reset via Mi Fit application

If the scales are connected to the smartphone, you can try to reboot them programmatically:

1. Open the Mi Fit app (or Zepp Life for new models).
2. Go to the Profile section → Devices → [Your scales].
3. Press three points (⋮) in the upper right corner and select Disable the device.
4. Wait 30 seconds and reconnect the scales via Bluetooth.

This method actually forcibly breaks the connection and forces the scales to restart the Bluetooth module, and after reconnecting the device should work more stable.

Hard reset (return to factory settings)

If the soft reboot didn’t work and Xiaomi’s scales still don’t work properly, a complete reset would be required, which removes all stored data (user profiles, weighing history) and returns the device to a “out of the box” state.

For different models, the procedure may differ:

After the hard reset:

1. The scales will automatically reset (it can take up to 1 minute).
2. The screen will display the 0.0 or Mi logo.
3. In the Mi Fit application, you will need to add the device again via Add the device → Libra.

⚠️ Warning: On Smart Scale 3 models, recalibration may be required after reset. Stand on the scale and hold the weight for 5 seconds - the device will automatically adjust the sensors.

💡

If the scales don't connect to the phone after reset, try changing the batteries to new ones (even if the old ones seem to work), often because of insufficient voltage.

What to do if Xiaomi scales do not respond to reset?

If neither the soft nor hard reset worked and the scales are still off, the reasons could be more serious:

• 🔋 Battery discharge, even if the indicator shows charge, the batteries may have lost capacity. Try replacing the batteries with alkaline batteries (for example, Duracell or Energizer).
• 💧 Wetting. Xiaomi scales don't have official water protection. If they're leaked, the device could have failed.
• 📱 Software firmware failure: If the scales freeze during the upgrade, they may stop responding to the buttons. The solution is to flash the device through a PC (instruction below).
• 🔌 Contact problems: Oxidation or contamination of battery contacts can disrupt power. Carefully clean them with a cotton swab dipped in alcohol.

If the scales are not turned on even after the battery replacement, try the following algorithm:

1. Remove the batteries for 5 minutes.
2. Press and hold the 30 seconds switch (this will drain the residual capacitor).
3. Insert new batteries and try to turn on the scales.

If the scales are still unresponsive after these manipulations, there is likely a controller failure or damage to the board, in which case it is recommended to contact the Xiaomi service center or replace the device under warranty (if the deadline is still valid).

Reflashing Xiaomi scales via PC (for power users)

If the scales hang during a firmware update or after a failed reset, forced flashing through a computer can help. nRF52832 (For example, Mi Body Composition Scale 2).

You'll need firmware.

• 🖥️ Computer with Windows or macOS.
• 🔌 USB-to-TTL cable (e.g., USB-to-TTL cable, CP2102 or FT232RL).
• 📂 Firmware for your model (you can download on the forums) 4PDA Xiaomi Community).
• 🛠️ The NRF Connect or J-Flash program.

Step-by-step:

1. Disassemble the scales by disconnecting the glass panel (carefully tuck it with a plastic card).
2. Connect the USB-to-TTL adapter to the contacts on the board (usually this is the case). VCC, GND, TX, RX).
3. Run nRF Connect and select the adapter’s port.
4. Download the firmware (.hex file) and start the writing process.
5. After completion, turn off the adapter, collect the scales and check the performance.

⚠️ Attention: The wrong firmware can permanently disable the scales. If you are not sure of your skills, you should consult a specialist.

Forums often feature firmware with modified interfaces (e.g., Home Assistant or alternative applications) but can cause the device to run unstable.

💡

Flashing is a last resort, and 90 percent of the time, the usual battery dumping or replacement helps.

Typical errors in resetting Xiaomi weights

Many users make the same mistakes when trying to reset Xiaomi scales, and here are the most common ones:

• ⏱️ Holding the button too short. You need to hold the button for a soft reset for at least 10 seconds, for a hard reset for up to 20 seconds.
• 🔋 Even if the indicator shows charge, the batteries may not provide enough current to reset. Always try new batteries.
• 📱 Ignoring firmware updates. If the scales are glitzy after the update, do not rush to reset them - first check whether the new version of the software has come out in Mi Fit.
• 💦 Attempt to reset wet scales: If water hits the platform, first dry the device for 24 hours (without using a hair dryer or heaters!).
• 🔌 Improper connection to PC when you're running firmware. Mixed contacts TX/RX or the wrong voltage can burn the charge.

Another common mistake is trying to lose weight through third-party apps (like Google Fit or Apple Health), which don’t have access to device settings and can’t initialize a reboot. Use only official software like Mi Fit or Zepp Life.

Failure prevention: how to avoid weight problems Xiaomi

To ensure that Xiaomi scales work consistently and do not require frequent reboot, follow these recommendations:

• 🔋 Use high-quality batteries. Cheap batteries discharge quickly and can cause failures. The best choice is Duracell alkaline batteries or Duracell batteries. GP.
• 📱 Update your firmware regularly. Mi Fit periodically releases bug fixing patches. Check for updates every 1-2 months.
• 🧹 Keep the scales clean. Dust and dirt on the contacts can disrupt the sensors. Rub the platform with a soft cloth, avoiding abrasives.
• 🚫 Don't drop the scales. A blow can damage the strain gauges, which will lead to incorrect readings. Always put the device on a flat surface.
• 🌡️ Avoid extreme temperatures. Don't leave the scales on the balcony in winter or in direct sunlight in summer. +10° before +40°S.

If you use Xiaomi scales with multiple users, regularly sync data in Mi Fit. this will help avoid profile conflicts that sometimes lead to freezes.

You should also disable automatic firmware updates in your application settings if you have an unstable Internet connection, and interrupted updates are one of the main reasons for the buildup of the scales.
