AMOLED-However, many users have difficulty setting up the bracelet for the first time: it doesn’t connect to the phone, doesn’t display notifications or discharges quickly. In this article, we will analyze the step-by-step instruction for setting up, taking into account all the nuances - from basic synchronization to subtle parameters like music control or alarm clock settings.

Particular attention will be paid to hidden functions that the manufacturer does not advertise: how to turn on the weather display, configure quick responses to messages or activate the “Do not disturb” mode on a schedule. You’ll also learn how to avoid common mistakes, such as why the bracelet may not display sleep data correctly if the firmware is not updated to the version. 1.0.9.54 The instructions are valid for all Mi Band modifications. 4 (including NFC-version and works on Android/iOS.

Preparation for setting up: what to do before connecting

Before you start syncing your bracelet to your phone, follow a few mandatory steps that will save you from common problems such as inability to connect or sensor failures.

First, check the compatibility of your smartphone. Mi Band 4 officially supports:

📱 Android 5.0 and higher with Google Play)
🍎 iOS 10.0 and higher (iPhone) 5s or newer)
🔄 Bluetooth 4.2 LE (Low Energy)

If your phone is older, the bracelet can connect, but some features (such as notifications or music control) won’t work, and make sure your smartphone turns off Bluetooth power saving mode – it often blocks a stable connection to wearable devices.

Install the Mi Fit application (links below)

Turn on Bluetooth on your phone

Charge the bracelet to 50% or higher

Disable VPN/proxy (can block Xiaomi servers)

Make sure your phone is free ≥500MB of memory

The second important point is charging the bracelet. Mi Band 4 comes with a partial charge, but for the first setup it is recommended to charge it to ≥50%. Use the original cable (included) and the power adapter on 5V/1A. Do not connect the bracelet to USB 3.0 (ports of blue) - this can cause the battery to overheat. The optimal first charge time is 1.5-2 hours.

Installation and configuration of the Mi Fit application

The official Mi Fit app is the only way to fully customize the Mi Band 4. Alternative programs (such as Notify & Fitness) allow you to expand the functionality, but they are not suitable for basic configuration.

🤖 Google Play (Android)
🍎 App Store (iOS)

Once installed, launch the app and register for a Xiaomi account (or log in to an existing one). This is a must-do step: without linking to the account, the bracelet will not sync data. When registering, specify a real email address, it will receive a confirmation email. If you use @gmail.com, check the Spam folder - emails from Xiaomi often get there.

Follow the step-by-step instructions:

Click "Add device" (the icon "+" in the upper right corner).
Select "Breasurement" → "Mi Smart Band 4".
Allow the app to access geodata, notifications and fitness data (required!).
Turn on Bluetooth on your phone and wait for the app to find the bracelet.

💡

If Mi Fit doesn’t find the bracelet, reboot the Bluetooth on your phone (turn off/on) and try again. Also make sure that the Mi Band 4 isn’t connected to another device (like a tablet).

Once successfully connected, the app will offer to update the bracelet firmware. It is not recommended to refuse the update - in older versions of the firmware (below 1.0.9.54) no control gestures work, and the heart rate sensor can give inaccurate data. The update process will take 5-10 minutes. Do not interrupt it and turn off Bluetooth!

Basic bracelet settings: time, notifications, screen

Once you connect to Mi Fit, open the Profile tab → “Mi Smart Band 4” → “Brecelet settings” and key settings are available here:

Parameter	Recommended values	Explanation
Automatic synchronization	Included.	Step, sleep and pulse data will be updated every 30 minutes.
Raising your hand to activate	Included.	The screen will light up when moving your hand (saves charge)
Screen brightness	3-to-4 level	At a maximum of 5, the bracelet discharges 20% faster.
Time format	24-hour	Avoiding confusion with AM/PM
Notifications	Included (selectively)	We recommend leaving only messengers and calls.

Pay special attention to the notification settings. By default, the Mi Band 4 vibrates at any alerts, which quickly lands the battery.

Go to Bracelet Settings → Notifications.
Disable unnecessary apps (such as games or social networks).
Turn on “Show Content” only for important messengers (WhatsApp, Telegram).
Set the Vibration level to 2-3 (maximum too aggressive).

How to turn off notifications during sleep?

Mi Fit does not have a direct function to block notifications on schedule, but you can use a workaround: 1. Enable Do Not Disturb mode on your phone (Android/iOS) for sleep time. 2. In the bracelet settings, turn off the option "Synchronize with DND mode of the phone" - this will prevent duplication of vibrations.

Another trick is to set the dial up, and there are over 70 official dials available in the Mi Band 4, but you can add custom dials.

Download the dial file (.bin format) from sites like AmazfitWatchFaces.
Place the file in the Mi folder Fit/watch_face phone-on.
In the app, select "Additional dials" → "Locals".

Setting up fitness functions: pedometer, pulse, sleep

The Mi Band 4 has sensors to track activity, but by default, the accuracy is poor, like a pedometer that can overstate 15-20 percent if not calibrated, to fix this:

Go to Profile → Mi Smart Band 4 → Pedometer settings.
Select Calibration and walk 20-30 steps with your phone in your hand.
Save calibration and synchronize the data.

To monitor your heart rate, we recommend you turn on "Continuous Measurement" (in your pulse settings), but note that this reduces the bracelet's operating time by 1-2 days. Alternatively, "Auto Measurement" every 30 minutes. If the pulse sensor gives you an error, check:

🩹 Density of the adhesive bracelet (should sit tightly, but not crush the vein).
🧼 Clean sensor (wipe with an alcohol napkin).
🔋 Charge level (at <15% sensor).

Sleep tracking is one of the most useful features of the Mi Band 4, but it requires the right setup. By default, the bracelet detects sleep automatically, but sometimes skips short naps. To improve accuracy:

Turn on "Sensitive sleep mode" in the settings.
Set the "Alarm clock for sleep phases" (awakening in the light phase).
Before going to bed, activate the "Do Not Disturb" mode (double pressing the bracelet screen).

💡

For accurate sleep tracking, wear a bracelet on your non-working hand (for right-handers - left, for left-handers - right) and place it 2-3 fingers above your wrist.
