Preparing for connection: what to do before synchronization

Before you start setting up, make sure you have everything you need. Xiaomi Mi Band 4 is compatible with most modern smartphones, but there are a few critical points:

• 📱 Smartphone on Android 5.0+ or iOS 10.0+ (iPhone requires Bluetooth 4.0).
• 🔋 Bracelet charge at least 50% - at low battery level synchronization may be interrupted.
• 📲 Mi Fitness (download to Google Play or App Store).

If you are updating the firmware of the bracelet from an older version, reset it to factory settings before connecting via the menu on the device (Settings → Reset). This will prevent conflicts between the versions of the software. Also check that the phone is enabled Bluetooth and geolocation (the latter is needed for accurate tracking of jogging).

⚠️ Note: If you use an iPhone, turn off the “Tracking Limit” feature in your privacy settings (Settings) → Confidentiality → Geolocation services → Mi Fitness → Otherwise, the bracelet will not be able to correctly fix the routes.

Installation and configuration of the Mi Fitness application

The official Mi Band 4 management app is Mi Fitness (formerly Mi Fit), which changed its interface in 2023, so old instructions can be misleading.

1. Download and install Mi Fitness from the official store (Google Play or App Store).
2. Launch the app and sign in to your Xiaomi account (or create a new one if you don’t have one).
3. Click Add Device in the upper right corner and select Bracelet → Mi Smart Band 4.
4. Allow the app to access notifications, contacts (to display callers' names) and geolocation.

After that, the app will prompt you to turn on Bluetooth and start searching for the bracelet. Make sure that the Mi Band 4 is near the phone (at a distance of no more than 10 m) and is not connected to other devices.

Step-by-step synchronization of Mi Band 4 with phone

Now, to the most important step, pairing the bracelet with the phone, follow the instructions carefully to avoid errors:

1. In the Mi Fitness app, click Add Device and select Mi Smart Band 4.
2. On the bracelet, swipe your finger up the screen to unlock it, then tap the "Bluetooth" icon (antenna icon).
3. You'll see a connection request on your phone, confirm it. If the bracelet isn't there, reboot Bluetooth on your smartphone.
4. Once you've successfully connected, the app will suggest you update your firmware, and you'll agree that this will fix the bugs and add new features.

If the bracelet is not connected, try:

• 🔄 Reboot both the bracelet and the phone.
• 📱 Remove Mi Band 4 from the list of conjugate devices in the Bluetooth settings of the phone.
• 🔧 Turn off the power saving mode on the smartphone (it can block the background work of Mi Fitness).

⚠️ Note: If you are using an iPhone with iOS 17+, Before connecting, disable the Bluetooth Frequency Limits function in the charge saving settings. Otherwise, the connection with the bracelet will be interrupted.

Set up notifications and calls

One of the key features of the Mi Band 4 is to display notifications from your phone, so you can set them up correctly:

1. In the Mi Fitness app, go to "Device Profile" → "Notifications".
2. Turn on the “Notifications” switch and select the applications you want to see on the bracelet (for example, WhatsApp, Telegram, Gmail).
3. Activate the “Show Content” option to see text messages (without it, only application icons will be displayed).
4. For calls, turn on "Call Notifications" and "Call Deflection" (allows you to drop incomings directly from the bracelet).

On Android, you can also set the vibration for different types of notifications:

• 📞 Calls are a long vibration.
• 💬 Messages - short pulses.
• ⏰ Alarm clocks are a repetitive vibration.

On the iPhone, notification functionality is limited by Apple’s policy: the bracelet will only show incoming calls and messages from standard apps (Messages, Mail). Telegram or Viber will require an additional Mi Band Master app (available only on Android).

💡

To ensure that notifications arrive without delay, add Mi Fitness to the battery optimization exception list (Settings → Battery → Optimization → All apps → Mi Fitness → No restrictions).

Personalization of screen and dials

The Mi Band 4 supports removable dials that can be downloaded directly from the app to change the look of the screen:

1. In Mi Fitness, go to "Device Profile" → "Display".
2. Select the Dials section and scroll through the list of options available. Free themes are marked with a green tick.
3. Click on your favorite dial and confirm the installation. Synchronization will take 10-30 seconds.

You can also set up:

• 🔦 Screen brightness (from 1 to 5 levels).
• ⏱️ Backlight time (5, 10 or 15 seconds).
• 🔄 Screen rotation (useful for left-handed people).

If standard dials are few, you can install custom ones through third-party apps like Amazfit Watchfaces (requires Android 8.0+).

1. Download your favorite dial in.bin format.
2. Transfer the file to the Mi Band 4 folder on your phone.
3. In Mi Fitness, update the dial list – a new option will appear at the end of the list.

Set up activity tracking and training

The Mi Band 4 can automatically recognize 6 activities: walking, running, cycling, gym, swimming and skiing, to customize your workouts:

1. In the app, go to "Profile" → "Training".
2. Select “Setting Goals” and specify the desired number of steps, calories, or activity times per day.
3. Activate Auto-Detection of Training if you want the bracelet to record the beginning of a jog or a bike ride.
4. For accurate distance tracking, turn on the phone's GPS (only works when connected to a smartphone).

For swimming:

• 🏊 Enable pool mode in bracelet settings (Settings) → Regimes → Swimming).
• 📏 Specify the length of the pool (from 25 to 50 m).
• 🔋 Charge the bracelet to 100% - in waterproof mode, battery consumption is higher.

After training, the data is automatically synchronized with the application, where you can view:

• 📊 Pulse and load schedule.
• 🏃 Route (if included) GPS).
• 🔥 Calorie consumption and time in the fat burning zone.

⚠️ Attention: If you're in a room with dumbbells or barbells, turn off Auto-Detection Training. The bracelet may misrepresent strength training as running, which will distort the statistics.

💡

For maximum accuracy of the pulsemeter, wear a bracelet 2-3 fingers above the wrist and tighten the strap so that the sensor is tightly attached to the skin, but does not squeeze the vessels.

Solving Typical Problems with Mi Band 4

Even after you set it up properly, you can have failures, and here are the most common problems and ways to fix them:

If the bracelet has stopped responding to touch, try:

1. Wipe the screen with a dry wipe (moisture or sweat can block the sensor).
2. Restart the device (press the touch button for 10 seconds).
3. Update the firmware through Mi Fitness.

For reset to factory settings:

1. On the bracelet, go to Settings → Reset.
2. Confirm the action by clicking the tick.
