How to set up a fitness bracelet Xiaomi Mi Band 4 after resetting to factory settings

Why Mi Band 4 Requires Resetting After Resetting

Resetting the Xiaomi Mi Band 4 to factory settings is a necessary measure when you freeze, sync errors or before transferring the device to a new owner. However, after this procedure, the bracelet becomes a “clean sheet”: all bindings to your Mi Account account, notification settings, training data and even time are reset. Without the right reset, the device will not be able to display incoming calls, show notifications from messengers or correctly record the pulse.

The main difficulty is that the Mi Band 4 does not have its own interface for full customization - 90% of the functions are configured through the Mi Fitness mobile application (formerly Mi Fit), while many users face problems: the bracelet is not determined by the phone, data does not synchronize or communication disappears after a few hours. In this article, we will analyze the step-by-step configuration algorithm with the typical errors and nuances of firmware in 2026.

It’s important to understand that even if you’ve set up the bracelet before, the process is different after the reset, such as re-authorizing your Xiaomi account, updating your bracelet firmware, or changing your region in your app settings, and then you’ll find a detailed instruction detailing each step.

Preparation for setting up: what to do before connecting

Before you start pairing your bracelet with your phone, follow a few mandatory steps, which can lead to errors such as Unable to connect or endless loading on the wristband screen.

• 📱 Update the Mi Fitness app to the latest version (at the time of 2026 – no lower than 5.12.0). Older versions may not support current Bluetooth protocols.
• 🔋 Charge the bracelet to minimum. 50%. Low charge (<20%) There may be failures during synchronization.
• 🌍 Check the region in your phone settings: if it’s different from China or Russia, some features (like weather) may not work properly.
• 🔄 Turn it off. VPN They block access to Xiaomi servers, which leads to authorization errors.

Pay special attention to the application permissions. Mi Fitness requires access to:

• 📍 Geolocations (to display weather)
• 📞 Contacts (to identify incoming calls)
• 💬 Notifications (to display messages)
• 📁 Storage (for backup of data)

If at least one of the permissions is disabled, the corresponding functions of the bracelet will not work. For example, without access to notifications, you will not see messages from WhatsApp or Telegram on the Mi Band 4 screen.

💡

If you have Android 12+, After installing Mi Fitness, go to your phone settings → "Annexes" → Mi Fitness → "Additionally" → "Show over other windows and turn on this setting. This will prevent communication breakdowns during synchronization.

Step-by-step: connect Mi Band 4 to the phone

Now, to the process of pairing, follow the instructions in strict order, and skipping the steps can lead to errors.

1. Turn on Bluetooth on your phone and make sure the bracelet is charged and is close (no further than 1 meter).
2. Launch the Mi Fitness app and log in to your Mi Account (if you haven’t already).
3. Click "Add device" (Icon "+" in the upper right corner) and select the bracelet → Mi Smart Band 4.
4. Hold your phone to the bracelet, and you're going to notice the device you found.
5. Confirm pairing on both devices: the phone will appear code that should match the code on the bracelet screen.
6. Wait until the synchronization is complete. It can take up to 5 minutes - don't interrupt the process!

If the bracelet displays an Update required message, it means that you need a firmware update. Don't ignore this notification - without the current firmware, some functions (such as monitoring sleep or stress) may not work properly.

Data recovery and setting up basic parameters

Once successfully connected, you need to adjust the bracelet's basic settings, and many users skip this step and then wonder why the bracelet is showing the wrong time or not counting the steps.

1. User profile setting

Go to Profile. → My devices. → Mi Smart Band 4 → Profile settings and specify:

• 👤 Gender (Affects Calorie Calorie Calculation Algorithms)
• 📏 Height and weight (for accurate steps and distance)
• 🎯 Steps target (recommended value of 8,000–10,000 per day)
• 🛌 Sleep time (to automatically switch to "Do Not Disturb" mode")

2. Restoration of backup

If you have previously used Mi Band 4 and backed up, you can recover the data:

1. Open Profile. → Settings → Recover data.
2. Select the last backup (see the date of creation in the file name).
3. Confirm the recovery and wait for the process to be completed.

Note that backups are only stored for 30 days, and if more than a month has passed since the last backup, the data will be lost.

3. Set up notifications

To have the bracelet show incoming calls and messages:

1. Go to Profile. → Mi Smart Band 4 → Notifications.
2. Turn on the Call Notification switch.
3. In the Notifications section of the apps, select messengers (for example, WhatsApp, Viber, Telegram).
4. Activate the option to Show Content if you want to see text messages (not just the sender’s name).

Firmware Update: Why It’s Critical and How to Do It Right

After resetting, Mi Band 4 often requires a firmware update, and you can't ignore this notification for three reasons:

1. Bug Fix: New firmware versions eliminate errors with synchronization, freezes and incorrect data display.
2. New features: For example, in firmware 1.0.9.54, support for displaying emojis in notifications has appeared.
3. Compatibility: Older firmware may conflict with the latest Mi Fitness versions.

To update the firmware:

1. Connect the bracelet to the charger and make sure the battery is charged >60%.
2. Open Mi Fitness, go to Profile → Mi Smart Band 4 → Firmware update.
3. If a new version is available, click Update and wait until the process is completed (usually takes 5-10 minutes).
4. Do not disconnect the bracelet from charging and do not close the application until the update is complete!

If the update is delayed during the Preparation for Update phase:

• 🔄 Reset the bracelet (press the touch button for 10 seconds).
• 📱 Reinstall the Mi Fitness app.
• 🌐 Check your internet connection (update downloaded from Xiaomi servers).

💡

Update your firmware only with a stable Internet connection (preferably via Wi-Fi). Using mobile Internet can lead to a download break and the bracelet "bricking".

Adjust additional functions: pulse, sports, weather

The basic setup is complete, but the Mi Band 4 supports a lot of extra features that need to be manually activated.

1. Heart rate monitoring

The bracelet automatically measures the pulse:

1. Go to Profile. → Mi Smart Band 4 → Monitoring of heart rate.
2. Enable the option of Automatic Measurement.
3. Set a measurement interval (recommended every 30 minutes for a balance between accuracy and battery consumption).
4. Activate High Pulse Notifications if you want to receive alerts when you exceed a predetermined threshold (e.g. 120 beats per minute).

Training regimes

Mi Band 4 supports 6 sports modes, but not all are enabled by default.

1. Open Profile. → Mi Smart Band 4 → Training regimens.
2. Click Add Mode and select from the list (e.g. Swimming, Bicycle, Treadmill).
3. Set goals for each mode (such as training time or distance).

3. Weather display

To show the weather on the bracelet screen:

• 📍 Enable geolocation for the Mi Fitness app.
• 🌤️ Go to Profile. → Mi Smart Band 4 → Weather and activate the option to show the weather.
• 🕒 Select the refresh rate (recommended every 6 hours).

If the weather is not displayed, check:

• Internet connection on the phone.
• Geolocation permission for Mi Fitness.
• Region in your phone settings (should match your actual location).

Solving typical problems after resetting settings

Even with the correct instructions, users often encounter errors, and let's look at the most common ones and how to fix them.

⚠️ Warning: If the bracelet stops detecting heart rate or steps after reset, check the strap's density. Even a small gap between the sensor and the skin can cause measurements to fail. Optimal position is 2-3 fingers above the wrist bone.

If none of these methods worked, try a hard reset:

1. Disconnect the bracelet from the application (profile) → Mi Smart Band 4 → Disable the device).
2. Reset the bracelet settings to factory (press the touch button for 20 seconds before the vibration appears).
3. Repeat the setup process from scratch.
