In this article, we will discuss the entire process from unpacking the bracelet to its full operation: how to properly charge the Mi Band 4, what applications you will need, how to synchronize data and avoid typical errors.

If you have just purchased a bracelet or plan to do so, bookmark this instruction, which will be useful not only for initial setup, but also for solving possible problems in the future.

1.Preparation for installation: what is included in the kit and what will be needed additionally

Before you start setting up, check the configuration of your Xiaomi Mi Band 4. The standard box should include:

• 📦 Mi Band 4 fitness bracelet (with battery installed)
• 🔌 Charging cable (special module with contacts)
• 📄 Short instructions in several languages (including Russian)
• 🔄 The band (usually already worn on the body)

If you don't have at least one of these items, you should go to the seller, and you should also pay attention to the integrity of the package, because if the box is opened or has traces of use, you're at risk of getting a used device.

In addition, you will need:

• 📱 Smartphone on Android 5.0+ or iOS 10.0+ Bluetooth 4.2 support
• 🌐 Stable Internet connection (for downloading applications and updates)
• 🔋 Power supply for bracelet charging (USB-port)

💡

If you have a Xiaomi, Redmi or POCO, Mi Fit can be preinstalled. Check the Tools or Health folder before downloading.

Important: Mi Band 4 doesn’t work autonomously — without pairing with a smartphone, you can’t set up notifications, synchronize step data, or sleep — but basic features (time, pedometer) will be available even without a connection.

Charging the bracelet before first switching on

The first launch of the Mi Band 4 always starts with charging, and although there is already a small charge from the factory, it is recommended to fully charge the device before setting up.

1. The bracelet firmware can be updated on the first connection, which requires energy.
2. Calibration of sensors (for example, accelerometer) is more accurate at full charge.

To charge the Mi Band 4:

1. Remove the bracelet from the strap by pressing the button on the back of the body.
2. Insert the bracelet module into the charging cable so that the contacts coincide (a slight click should be heard).
3. Connect the cable to the power source (USB-port 5V/1A).

Charging indication:

• 🔴 Red indicator - charging is going.
• 🟢 Green indicator – charging is completed (usually after 1.5-2 hours).

Important: Do not use chargers with a current greater than 1A – this can shorten the life of the bracelet battery.

3. Install Mi Fit app and create an account

For full operation of Xiaomi Mi Band 4 requires the official application Mi Fit. It is available for Android and iOS, but there are nuances:

For Android:

• 🤖 Download the app from Google Play.

2. Create a Xiaomi account (or sign in if you already have one). Without an account, you won’t be able to sync data between devices.
3. Fill out the profile: specify gender, age, weight and height – this is necessary for accurate calorie and activity calculation.
