How to turn on Xiaomi Mi Band 4 smart watch: from charging to first setup

Smart watch Xiaomi Mi Band 4 remain one of the most popular fitness trackers due to the combination of affordable price, compactness and wide functionality. However, even such a simple device can puzzle a beginner: what to do if the bracelet does not respond to clicks, does not turn on after purchase or has been lying idle for a long time? In this article, we will analyze all possible scenarios – from the first charge to reset if the Mi Band 4 refuses to turn on.

It is important to understand that the activation process depends on the condition of the device: a new bracelet out of the box, a discharged battery after storage or a software failure require different approaches. We will consider each case separately, and also give recommendations for eliminating typical problems.

Preparation for the first inclusion: what to check before the start

Before you try to turn on the Xiaomi Mi Band 4, make sure that the basic conditions are met. Often users face problems due to missed steps in the preparation stage.

• 🔋 Charge the device. Even if the bracelet is new, its battery may have run out during storage. Connect the Mi Band 4 to the charger for 30 to 60 minutes before first turning on.
• 📱 Install the app. It requires the official Mi Fit app (or Zepp Life for newer versions) to work properly. Download it from Google Play or the App Store.
• 🔄 Smartphone compatibility. Make sure your phone runs Android 5.0+ or iOS 10.0+. Older versions of the OS may not support synchronization.
• 🔌 Cable and power supply. Use the original charging cable (or certified analogue) and the power supply with output. 5V/1A. Inappropriate chargers can damage the battery.

Pay special attention to the status of the contacts on the bracelet and charger. If they are oxidized or contaminated, clean them with a soft napkin dipped in alcohol. Also check if the bracelet capsule is tightly fixed in the charging socket - weak contact can interrupt the charging process.

⚠️ Note: Do not use abrasive materials ( sandpaper, metal brushes) to clean contacts - this will damage the coating and worsen conductivity.

How to Charge Xiaomi Mi Band 4 Before First Enablement

The Mi Band 4 battery has a capacity of 135 mAh, which provides up to 20 days of moderate use, but before the first turn on it must be charged — even if the indicator shows a residual charge.

1. Connect the charger to the power source (USB-port of the computer or network adapter).
2. Remove the bracelet capsule from the strap by pressing the button from the back.
3. Place the capsule in the charging socket so that the metal contacts on the bracelet match the contacts on the charger.
4. Wait for the indication to appear. The charge icon (lightning) should appear on the bracelet screen, and below it is the percentage of charge.

The full charge time is about 2 hours. If the indicator does not appear within 5-10 minutes, check:

• 🔌 Density of contact between bracelet and charger.
• 🔋 Cable and power supply performance (try another charger).
• 📱 Battery condition (if the bracelet has been discharged for a long time, it may be necessary to "rock" the battery).

If the bracelet doesn't respond to charging at all, try holding it on the charger for 10-15 minutes - sometimes a discharged battery needs a "push" to start charging. If that doesn't help, go to the section on resetting.

The first inclusion process: step-by-step instructions

When the bracelet is charged (at least 20-30%), you can start turning on. There is no physical power button in the Xiaomi Mi Band 4 - control is carried out through the touch screen.

1. Press the touch screen of the bracelet and hold your finger for 2-3 seconds until the Mi logo appears.
2. Wait for the download. The download animation and the main menu will appear sequentially on the screen.
3. Select a language (if required). In some firmware, the first run is accompanied by a choice of language - swipe the list up/down and tap the desired item.
4. Connect to your smartphone. Open the Mi Fit app, go to Profile → Add the device and follow the instructions on the screen.

If the screen does not respond to touch, try:

• 👆 Swipe up/down – sometimes the sensor responds better to vertical movements.
• 💧 Wipe the screen with a dry wipe (wet fingers or dirt may interfere with the operation).
• 🔄 Reboot the bracelet by plugging it into charging for 10 seconds, then turning it off.

💡

If the Mi Band 4 screen doesn’t respond to touch, try removing the protective film (if you have one) – sometimes it blocks the sensor.

Once you're successful, you'll see time, steps, and other data on the screen, and if the time isn't displayed correctly, sync it to your phone through the Mi Fit app.

Synchronization with the phone: the connection of the bracelet and smartphone

Without a smartphone connection, the Xiaomi Mi Band 4 runs in limited mode — it doesn't display notifications, sync health data, or update firmware.

1. Install Mi Fit or Zepp Life (for new firmware versions).
2. Sign up or sign in to your Xiaomi account (via Google/Facebook).
3. Add device: Open Mi Fit → Profile → Add device → Mi Smart Band 4
4. Follow the instructions on the screen. The app will suggest turning on Bluetooth, allowing notifications and access to contacts.

If the bracelet is not in the app, check:

If the bracelet is permanently turned off after synchronization, try turning off the power saving mode for the Mi Fit app in the phone settings, which is especially true for Android devices with aggressive battery optimization (e.g. Xiaomi, Huawei).

What to do if Xiaomi Mi Band 4 is not included

If the bracelet does not respond to charging or touching, the reasons can be both software and hardware.

Resetting settings to factory

Hard reset helps with software failures, but erases all data from the bracelet.

2. Press and hold the touch screen for 10-15 seconds until you feel the vibration.
3. Release the screen - the bracelet will reboot and return to factory settings.

Battery problems

If the bracelet is not charged at all, the following reasons are possible:

• 🔋 Deep discharge. The battery may have failed after long storage in a discharged state. Try leaving the bracelet on charge for 12 to 24 hours.
• 🔌 Faulty cable. Check the charger on another bracelet or smartphone.
• 💧 If the bracelet has been in contact with water, dry it in rice or silica gel for 24 hours.

⚠️ Warning: Do not try to disassemble the bracelet yourself to replace the battery - this will lead to loss of water protection and cancel the warranty (if it is still valid.

Firmware problems

If the bracelet is turned on, but it is unstable (hangs, does not sync), try updating the firmware:

1. Open Mi Fit and go to Profile → Mi Smart Band 4 → Firmware Update.
2. If the update is available, plug the bracelet into charging and wait for the process to complete (don’t turn it off!).
3. After the update, reset the settings (see above).
