How to set up Xiaomi Mi Band 4 after resetting to factory settings: the full guide

Resetting the Xiaomi Mi Band 4 to factory settings is a necessary measure when you freeze, synchronize errors or before selling a device. However, after this procedure, the bracelet becomes a “clean sheet”: you disappear the data about steps, pulse, sleep patterns, as well as all personal settings – from alarm clocks to notifications from the phone. You can restore the gadget in 10-15 minutes, but only if you know the key nuances.

In this article, we will look at the step-by-step configuration of the Mi Band 4 after reset, from connecting to the Mi Fit app (or Zepp Life) to finely calibrating sensors and restoring backups. We will focus on common errors, such as why the bracelet is not detected by the phone or why data from the past days has disappeared after synchronization, and if you encounter one of these problems, you will find solutions below.

Note: the instructions are relevant for all versions of the Mi Band firmware 4 (including 1.0.9.54 and newer) and works on Android/iOS. For owners of bracelets with Chinese firmware (without the letter C in the model number) added separate recommendations.

1. Preparation for setting up: what to do before connecting

Before you start setting up, make sure you have everything you need, and without these prepared elements, the process can be delayed or fail.

Mandatory conditions:

• 📱 Smartphone on Android 5.0+ or iOS 10.0+ It's important that if you've used Mi Fit before, don't delete it, because it backs up your data.
• 🔋 At a level below 20%, the Mi Band 4 can be turned off during synchronization.
• 📶 Stable Internet connection (Wi-Fi or mobile network). Mi Fit app downloads up-to-date data about firmware and regional settings.
• 🔄 You can turn on Bluetooth and geolocation on your phone. You can't find a bracelet without it.

If you have reset your settings due to sync issues, check:

• 🛡️ Not on the phone. VPN Firewalls that block the connection to Xiaomi servers (e.g. api.mi.com or account.xiaomi.com).
• 📲 Is the Mi Fit app updated to the latest version?Older versions may not support new bracelet firmware.

⚠️ Note: If you reset the bracelet through the Settings menu → Reset, not through the app, step and sleep data over the past 7 days will be irretrievably lost.The Mi Fit app stores only aggregated statistics, and the detailed data remains in the wristband's memory.

2. Connecting Mi Band 4 to the phone: step-by-step instructions

After resetting, the bracelet goes into standby mode, and to wake it up, follow the following steps:

1. Turn on Bluetooth on your phone and launch the Mi Fit (or Zepp Life) app.
2. Click on the profile icon in the upper right corner, then select Add Device.
3. In the list of available gadgets, select Mi Smart Band 4 (Not to be confused with Mi Band 5/6!).
4. Hold your phone to the bracelet at a distance of less than 10 cm and wait for the vibration. On the screen Mi Band 4 will appear the confirmation code — compare it with the code in the application.
5. Confirm the pairing on both devices.

If the bracelet is not present, try:

• 🔄 Reboot Mi Band 4 (press the touch button for 10 seconds before vibration).
• 📱 Restart Bluetooth on your phone or enable Device Search».
• 🚫 Remove the bracelet from the list of conjugate devices in the Bluetooth settings of the phone (if it is there).

Once you've successfully connected, the app will suggest you update your firmware, and don't give up the update, which will fix any bugs and add support for new features, and it'll take 2-5 minutes, and the bracelet will reboot automatically.

3. Data recovery and backup copies

One of the biggest fears after a reset is that you lose your statistics. Fortunately, Mi Fit automatically backs up some of the data on Xiaomi's servers.

To recover as much data as possible:

1. Open Mi Fit and wait for the first sync (cloud icon in the upper right corner).
2. Go to Profile. → Mi Smart Band 4 → Settings → Recover data.
3. If the option is not available, check if your Mi Account is linked to the bracelet (in profile settings).

⚠️ Note: If you have used multiple Xiaomi accounts on the same bracelet, the data may be shared between them.

💡

To avoid future data loss, enable Autosynchronization in Mi Fit (Profile) → Settings → This will save statistics on Xiaomi servers every 30 minutes.

4. Customization of the main functions: pedometer, pulse, notifications

Once you've recovered the data, set up the key features of the bracelet. Most of the settings are available through the Mi Fit app.

Stepper and activity objectives

To make sure the bracelet counts the steps accurately:

1. Go to Profile. → Mi Smart Band 4 → Steps.
2. Specify your height, weight and step length (by default 70 cm for men and 60 cm for women).
3. Enable the option of Smart Walk Detection (if you want the bracelet to automatically recognize walks).

Monitoring of heart rate

For accurate pulse measurement:

• 🩺 Wear the bracelet 2-3 cm above the wrist bone (not too tight!).
• 🔄 Turn on Continuous Monitoring in your pulse settings (discharges the battery faster, but gives you a full picture).
• ⚠️ Turn off the function during sleep if you don’t need detailing – it will save up to 20% of charge.

Notifications from the telephone

To make the bracelet vibrate when calling and texting:

1. In Mi Fit, go to Profile → Mi Smart Band 4 → Notifications.
2. Turn on the option to display notifications.
3. Select the apps you want to see alerts from (such as WhatsApp, Telegram, Gmail).
4. Set up the Notification Style: Vibration only or with text display.

If notifications do not arrive:

• 📵 Check if the Mi Fit app is added to the list of “Battery Optimization” on Android (this blocks background work).
• 🔕 Make sure the phone does not turn on the “Do Not Disturb” mode».

💡

To accurately measure your pulse during exercise, turn off continuous monitoring and use manual measurements to save charge and reduce error.

5.Setting up additional functions: alarm clocks, training, weather

The Mi Band 4 supports a number of useful "chips" that often go unused.

Alarm clocks

The bracelet can vibrate at a given time, even if the phone is turned off.

1. In Mi Fit, select a Profile. → Mi Smart Band 4 → Alarm clocks.
2. Click Add an alarm and specify the time, days of the week and type of vibration.
3. Activate the option to Repeat if the alarm is needed on a regular basis.

You can add up to 10 alarm clocks at the same time.

5.2 Training regimes

The Mi Band 4 recognizes 6 activities: running, walking, cycling, gym, swimming and an elliptical trainer.

• 🏃 On the bracelet, swipe up the screen and select Training.
• 📊 Select the type of activity and confirm the start (bracelet vibrates).
• ⏱️ At the end, click on the bracelet button – the data is automatically synchronized with Mi Fit.

Weather and other widgets

On the main screen of the bracelet, you can add weather widgets, calendar event notifications, and even music controls.

1. In Mi Fit go to Profile → Mi Smart Band 4 → Bracelet screen.
2. Select Screen Setting and add the desired widgets to the list.
3. On the bracelet, swipe right/left to switch between them.

To display the weather, you need:

• 🌍 Enable geolocation on the phone.
• 🔄 Allow Mi Fit to access location.
• 📡 Wait for the first synchronization (data is updated every 3 hours).

6. Solving typical problems after discharge

Even when you set up correctly, Mi Band 4 users sometimes encounter bugs, and let’s look at the most common ones and how to fix them.

6.1 The bracelet is not synchronized with the phone

Causes and solutions:

• 📵 Bluetooth is off – check your phone settings.
• 🔄 Outdated firmware - update the bracelet through Mi Fit.
• 🛡️ Antivirus Block – Add Mi Fit to Exceptions.
• 📱 App cache – clear the Mi Fit cache in your phone settings.

The battery is discharged rapidly

If the bracelet discharges in 1-2 days instead of the promised 20, check:

• ⚡ Continuous pulse monitoring – turn it off or reduce the frequency of measurements.
• 📶 Constant connection to the phone - turn on the Energy Saving mode in the bracelet settings.
• 🔦 Screen brightness – reduce it to 2-3 divisions.
• 🛠️ Background apps – close unnecessary widgets on your bracelet.

6.3 Vibration is not working

If the bracelet does not vibrate at notifications:

1. Check if vibration is included in Profile settings → Mi Smart Band 4 → Notifications.
2. Make sure the bracelet does not activate Do Not Disturb mode (swipe down the screen and check the bell icon).
3. Reset the bracelet (hold the button for 10 seconds).

⚠️ Note: If the Mi Band 4 bracelet shows Chinese characters instead of a menu, it has firmware for the Chinese region. To fix, update the firmware through Mi Fit with a Xiaomi account tied (not Mi Account!).

7. Optimization of the bracelet: tips for advanced users

If you want to make the most of Mi Band 4, use these tips:

Improved pedometer accuracy

Standard settings can understate or overstate the number of steps, to calibrate:

• Walk exactly 50 steps with your phone in your hand (use the standard Stepmer app for control).
• Compare the data to the bracelet readings. If the difference is greater than 10%, adjust the stride length in Mi Fit.

7.2. Use of third-party firmware

For enthusiasts, custom firmware (such as Amazfit Mod) is available, which add:

• 🎨 New dials.
• 📊 Expanded training statistics.
• 🔧 Additional screen settings.

⚠️ Risk: Unofficial firmware can lead to loss of warranty and unstable operation of sensors.

7.3 Synchronization with other services

Mi Fit supports integration with:

• 🏃 Google Fit – to export step and workout data.
• 🍏 Apple Health for iPhone users.
• 🌍 Strava – for cyclists and runners.

To connect, go to the Profile. → Settings → Connected applications.

💡

If you're swimming, manually activate swimming mode before you exercise. Automatic recognition only works when you're in high-intensity movements.
