How to install and configure the Xiaomi Mi Band 4 fitness bracelet

Why do you need the right Mi Band 4 installation?

The Xiaomi Mi Band 4 fitness bracelet is one of the most popular devices for monitoring activity, sleep and health. However, even such a simple device requires the right initial setup to unleash its full potential. Many users face problems when connecting for the first time: the bracelet is not determined by the smartphone, data is not synchronized, or the Mi Fit application emits errors. In this article, we will analyze the step-by-step instructions for installing the Mi Band 4 to avoid typical errors and maximize the use of all the functions of the device.

The Mi Band 4 is versatile: it is compatible with both Android and iOS, but the setup process on these platforms is nuanced. In addition, the bracelet supports interchangeable straps, waterproof up to 50 meters and advanced tracking functions (pulse, steps, calories, notifications). However, without proper installation, many of these features will remain unavailable.

Preparation for installation: what will be needed?

Before you start setting up, make sure you have everything you need. Here is the minimum set for a successful Mi Band 4 installation:

• 📱 Smartphone on Android 5.0+ or iOS 10.0+ Bluetooth 4.2 support.
• 🔋 Charged bracelet (minimum 20% charge, better than 50%).
• 📲 Mi Fit (last version from the App Store or Google Play).

If you have an older version of Mi Fit, update it before connecting. Outdated versions of the app may not support new Mi Band 4 features, such as notification display or sleep monitoring, and check if Bluetooth and geolocation are enabled on your smartphone (the latter is needed to accurately track activity).

⚠️ Warning: If you are upgrading with Mi Band 3, reset your old bracelet to factory settings via Settings → Untie the device in Mi Fit. Otherwise, conflicts may arise during synchronization.

Step 1: Charging the bracelet before first switching on

The new Mi Band 4 comes with a partially discharged battery. Be sure to charge it to 100% before the first switch on.

1. Remove the bracelet from the package and remove the protective film from the screen.
2. Connect the charging cable to USB-port (you can use a smartphone adapter).
3. Insert the bracelet into the charging pad so that the contacts coincide (a click should be heard).
4. Wait for the charging icon (battery with lightning) to appear on the screen.

The full charge time is about 1.5-2 hours. Don't interrupt the process, even if the bracelet is 100%, wait until the charging indicator disappears. This ensures that the battery is calibrated correctly.

⚠️ Note: Do not use cables from other devices (e.g. Mi Band 3 or smartphones) to charge the Mi Band 4, which can cause damage to contacts or slow charging.

Step 2: Install and configure the Mi Fit application

The Mi Fit app is the control center for your bracelet, and without it, you can't sync data, update firmware, or adjust notifications.

• 🤖 For Android: Google Play.
• 🍎 For iOS: App Store.

After installation:

1. Open Mi Fit and register (you can use Xiaomi Account, Google or Facebook).
2. Log in and fill in the basic data: gender, age, weight, height, and you need it to accurately calculate calories and activity.
3. Allow all permissions (access to geolocation, notifications, contacts).

If you already had a Xiaomi bracelet, the app may suggest moving settings.Back this if you switch from another model (such as the Mi Band 3) to avoid conflicts.

💡

If Mi Fit doesn’t find the bracelet, try restarting Bluetooth on your smartphone or reinstalling the app.

Step 3: Sync Mi Band 4 with a smartphone

Now, to the most important step, which is to connect the bracelet.

1. Turn on Bluetooth on your smartphone.
2. Open Mi Fit and click Profile → Add the device.
3. Choose from the list of Mi Smart Band 4.
4. Press the bracelet screen to unlock it (if it is locked).
5. Bring the bracelet close to the phone (at a distance of 10-15 cm).
6. Confirm the pairing on both devices.

If the bracelet is not defined:

• 🔄 Reboot the Mi Band 4 (press the touch button for 10 seconds until the Mi logo appears).
• 📱 Restart Bluetooth on your smartphone.
• 🔧 Make sure there are no active phones on the phone. VPN or energy saving modes blocking the connection.

Critical detail: If you use a Xiaomi smartphone, turn off the dual apps feature for Mi Fit (it can create synchronization conflicts).

Step 4: Initial bracelet setting

After successful synchronization, set the main parameters:

1. Language and time: Go to Profile → Mi Smart Band 4 → Display settings and select the language (Russian available).
2. Notifications: Enable the Notifications option and select the apps you want to see on your bracelet (e.g. WhatsApp, Viber, Calls).
3. Sleep tracking: Activate in Settings → Sleep monitoring. For accuracy, wear the bracelet on a non-dominant hand (for example, your left hand if you are right-handed).
4. Activity goals: Set daily goals by steps (8000-10,000 for beginners is recommended).

You can also set up:

• 🔍 Raising your hand to activate the screen (convenient but shortens battery life).
• 🌙 Do not disturb during sleep or meetings.
• 🏃 Autodetermining training (running, walking, cycling).

Step 5: Update the firmware and install dials

After connecting, check for firmware updates:

1. Open Mi Fit and go to Profile → Mi Smart Band 4 → Firmware Update.
2. If an update is available, plug the bracelet into charging and wait for the process to complete (5-10 minutes).
3. Do not disconnect the bracelet from charging and do not interrupt the connection with the smartphone!

Updates add new features, fix bugs and improve stability, such as the latest firmware versions for the Mi Band 4, which include support for music control gestures and an improved pulse measurement algorithm.

You can also set custom dials:

• 🎨 Download dials from apps like Amazfit Watchfaces or Notify & Fitness.
• 📲 Download the dial file (.bin) via Mi Fit in the Dials section.
• 🔄 Synchronize the bracelet to apply changes.

⚠️ Warning: Installing unofficial dials can cause malfunctions in the bracelet. Use only verified sources and back up the data before experimenting.

💡

Update your Mi Band 4 firmware regularly to improve sensor accuracy and add new features such as stress or breathing monitoring.

Step 6: Optimizing your work and troubleshooting

Even after a successful setup, problems can arise, and here are the most common ways to solve them:

If the bracelet is no longer synchronized, try:

1. Reset the bracelet (click the button for 10 seconds).
2. Remove it from Mi Fit and reconnect it.
3. Clear the cache of the Mi Fit application in the smartphone settings.

In most cases, these actions solve the problem. If not, check the bracelet on another smartphone to rule out a hardware defect.
