Xiaomi Mi Band 4: how to properly start and configure the bracelet from scratch

First acquaintance with Mi Band 4: what is in the box and how not to spoil the bracelet when unpacking

The Xiaomi Mi Band 4 fitness bracelet remains one of the most popular activity tracking gadgets even years after its release, and its simplicity, reliability and rich functionality appeal to both beginners and experienced users. However, the first launch often raises questions: how to properly remove the bracelet from the package, what to do with the charger, and how to avoid typical errors when turned on?

In the Mi Band 4 box, you'll find the bracelet itself in a protective film, the sensor capsule (removable module), the strap (usually black or colored, depending on the configuration), the magnetic contact charger and a brief instruction in several languages. Important: don't try to force the capsule from the strap - it is fixed by a special mechanism that can be damaged. Also check the integrity of the sealing ring on the back of the module: it protects from moisture and dust.

Before you start setting up, make sure you have: Android 5.0 smartphone+ or iOS 10.0+, Mi Fit (or Zepp Life for newer versions) and original USB-The bracelet supports Bluetooth 5.0, but for stable synchronization, it is better to use devices no older than 5 years.

Step 1: Charging the bracelet before first switching on

Even if the Mi Band 4 has a residual charge from the factory, the first charge is mandatory.This is because the bracelet could have been in storage for a long time and its battery was discharged to a critical level. Use only the original charger - third-party adapters can damage the contacts or cause overheating.

How to charge correctly:

1. Remove the capsule from the strap by pulling it sideways (not up!).
2. Attach the module to the charger – the magnets must securely fix it.
3. Connect. USB-cable to power supply (computer, phone charger or power bank).

The charging indicator will turn red, which means that the process has started. It takes about 2 hours to fully charge, after which the indicator will go out.

⚠️ Note: Do not use chargers with higher voltage 5V/1A. Overloading can cause the battery to bloat and the bracelet to fail. Also avoid charging at lower temperatures. 0°C or higher 40°C.

After charging, don’t be in a hurry to turn off the bracelet – let it stand on charging for another 10-15 minutes, which will help stabilize the battery level and avoid sudden shutdowns in the first days of use.

Step 2: Installation of the application and registration of the account

Without the official Mi Fit or Zepp Life app, the Mi Band 4 will only work like a pedometer clock, and to unlock all the functionality (notifications, sleep monitoring, heart rate, etc.), you need to:

• 📱 Download Mi Fit from Google Play or App Store.
• 🔑 Register a Xiaomi account (or log in through an existing one).
• 🔄 Updating the application to the latest version will eliminate synchronization errors.

When registering for an account, provide a real email address, which will be needed to restore access if you forget your password, and we also recommend that you enable two-factor authentication in your profile settings.

⚠️ Note: If you use Mi Band 4 in China, the app may request a Chinese phone number binding.

Once you log in, the app will suggest adding a new device. Select Bracelet → Mi Smart Band 4 and follow the instructions on the screen. At this point, the bracelet should be on and next to the smartphone.

Step 3: First Enable and Sync with Your Phone

Step 4: Basic setting: time, notifications and user profile

Next, set up notifications:

• 📩 Turn on call alerts, SMS and messengers (WhatsApp, Telegram, etc.).
• ⏰ Set alarm clocks (bracelet vibrates without making a sound).
• 🔕 Turn off unnecessary notifications (such as from games) to avoid wasting charge.

In the Display and Brightness section, select:

• 🌓 Automatic brightness control (saves battery life).
• ⏱ Screen time (5-10 seconds) is sufficient).
• 🎨 Color scheme of the dial (in Mi Band 4 available 5 built-in themes).

💡

If notifications don't come, check the power saving settings on your phone. On Xiaomi, Huawei and Samsung, you need to manually add Mi Fit to the background work exception list.

Step 5: Update the firmware and install additional features

After the first setup, it is recommended to update the firmware of the bracelet, this will fix bugs, add new features and improve stability.
