Xiaomi Mi Smart Band 4: How to turn on the bracelet for the first time, restart or wake up after discharging

Mi Smart Band 4: Where to Start?

The Xiaomi Mi Smart Band 4 fitness bracelet remains one of the most popular gadgets for tracking activity even years after its release. However, new users often have questions: how to turn on the device for the first time, what to do if the screen does not respond, and how to sync it with a smartphone. In this article, we will analyze all the nuances from charging to settings through the Mi Fit app.

The design of the bracelet is very simple: there are no physical buttons, and control is through the touch screen and gestures, which means that the first turn on is possible only after connecting to the charger - without it, the bracelet is in "sleep" mode with a fully discharged battery. If you bought a new device, it is likely to be discharged to zero in stock.

It is important to understand the difference between the bracelet states:

• 🔋 Fully discharged – the screen does not respond to touch, the charging indicator does not burn.
• 🔄 Reboot – the Mi logo appears on the screen, then download animation.
• 📱 Active mode – the screen is turned on when raising your hand or pressing.

If you have purchased a used bracelet, we recommend that you reset it to factory settings before you first turn on, which will eliminate any problems with linking to your previous account, and you will find the reset instructions in one of the following sections.

Step 1: Charging the bracelet before first switching on

Without charging, the Mi Band 4 won't turn on, which is a key point. It comes with a special charger cable with a magnetic connector. Here's how to plug it in correctly:

1. 🔌 Remove the bracelet capsule from the strap by pulling it towards the screen.
2. 🧲 Attach the magnetic cable connector to the contacts on the back of the capsule (they are located at the bottom of the capsule).
3. 🔋 Connect. USB-cable-connector (5V/1A) computer.

If you successfully connect the bracelet, you'll see a charging indicator on the screen, a red battery with an animation of filling.

Make sure the capsule contacts are clean (wipe with alcohol)|Try turning the magnetic connector over.|Use another one. USB-port|Check the integrity of the cable (a common problem is a cliff at the base)

-->

The full charge time is about 1.5-2 hours, and once you reach 100%, the indicator will change to a green battery, and now you can turn off the cable and switch to power.

💡

If the bracelet does not respond to charging for more than 10 minutes, try resetting it by holding the sensor for 20 seconds (if the screen responds in any way).

Step 2: Turning on the bracelet after charging

When the Mi Band 4 is charged, it automatically turns on, but if the screen is still black, do the following:

1. 🖐️ Touch the touch screen of the bracelet with one finger and hold for 3-5 seconds.
2. 🔄 If the screen is not responding, plug the bracelet into charging again for 10-15 minutes – sometimes additional charging is required to activate the bracelet.
3. 📱 Install the Mi Fit app (or Zepp Life for newer versions) on your smartphone and try syncing – this can wake up the bracelet.

When successfully incorporated, you will see:

• 🌐 Mi logo on a black background (system boot).
• ⚙️ Customization animation (if the bracelet is new).
• ⏱️ Main screen with time (if the bracelet has already been set up).

If the bracelet turns on but turns off, the problem is with the battery being discharged. Connect it to charging for at least 30 minutes, even if the indicator is 100%. Sometimes the power controller takes time to calibrate.

Step 3: Sync with Mi Fit or Zepp Life

Without a smartphone connection, the Mi Band 4 only works like a pedometer clock, and to unlock all functions (notifications, sleep monitoring, pulsemeter), you need to synchronize the bracelet with the official app.

Download Mi Fit (for Android/iOS) or Zepp Life (a new name for some regions) and follow the instructions:

1. 📱 Register or log in to your account Xiaomi/Zepp.
2. ➕ Press "Add device" → Choose "Breasure" → "Mi Smart Band 4".
3. 🔍 Turn on Bluetooth on your smartphone and allow the app to access geodata (required!).
4. 🔗 Wait for the app to find the bracelet (it should vibrate when connected).

After successful synchronization, the app will suggest updating the bracelet firmware. We recommend you agree - this will fix possible bugs and add new features. The update takes 5-10 minutes, the bracelet will reboot automatically.

Step 4: Reset and Force Bracelet Shutdown

Sometimes the Mi Band 4 can freeze, the screen doesn't respond to touch, or the bracelet doesn't sync with the smartphone, and in these cases, rebooting helps. Here's how to do it:

Soft reboot (if the screen reacts):

1. 🔄 Swipe your finger from left to right across the screen to open the menu.
2. 🔋 Find the item "Reset" (circle arrow icon) and tap it.
3. ⏳ Confirm the action – the bracelet vibrates and reboots.

Hard reboot (if the screen is not responsive):

1. 🔌 Connect the bracelet to charging.
2. 🖐️ Hold your finger on the sensor for 15-20 seconds until you feel vibration.
3. 🔄 Release your finger – the bracelet will reboot (the Mi logo will appear).

💡

Hard reset erases all data on the bracelet (steps, settings), but does not affect the data in the Mi Fit account.

If the bracelet doesn't reboot even after the sensor is held, the problem could be a hardware failure.

• 🔋 Try to completely discharge the bracelet (leave without charging for 12).+ hours, then recharge the charge.
• 🔧 Contact the service center - possible malfunction of the battery or board.

Step 5: Reset to factory settings

Reset is required in three cases:

1. The bracelet is tied to someone else’s Xiaomi account.
2. You want to sell or transfer the bracelet to another person.
3. The settings are off and the bracelet is not working properly.

You can perform the reset in two ways:

Method 1: Through the menu of the bracelet

1. 🔄 Swipe left to right on the screen to open the menu.
2. ⚙️ Find the "Settings" item (cog icon).
3. 🗑️ Scroll down to "Dump" → "Reset to factory".
4. ✅ Confirm the action – the bracelet vibrates and reboots.

Method 2: Through the Mi Fit application

1. 📱 Open Mi Fit. → Go to the profile of the bracelet.
2. ⚙️ Click on three dots in the upper right corner → "Disable the device".
3. 🔄 Confirm the disconnection – the bracelet will be reset automatically.

💡

Once reset, the bracelet will return to the default language (Chinese), and to change the language, sync it with the app again and select the language you want in your settings.

If the reset doesn’t work (for example, the bracelet still asks for an old account), the problem may be in the firmware, in which case the firmware via the PC using the MiBand4Tool utility will help, and you will find the instructions for firmware in specialized forums (for example, 4PDA).

Step 6: Address common inclusion issues

Even after charging and resetting correctly, the Mi Band 4 may not turn on.

If the bracelet has fallen into water or has been subjected to severe humidity, before turning on:
