Launching the Xiaomi Mi Band 3 is a process that may seem trivial, but beginners often have questions, especially if the device has been lying on the shelf for a long time or was bought used. The main difficulty is that this tracker does not have a physical on button, and the OLED screen remains black until the moment of full synchronization with the smartphone. Many users mistakenly believe that the gadget is faulty when it does not respond to touch immediately after being removed from the package.
To activate the tracker, you will need a modern Bluetooth-enabled smartphone and an installed Mi Fit app (or its current Zepp Life analogue). The initial setup process requires a stable Internet connection, since the device needs to download the user profile and update the firmware to the current version. Without this step, the functionality of the bracelet will be severely limited, and the sensors may not work correctly.
In this article, we will take a detailed look at all the steps of activation, from checking battery power to solving specific connection problems. You will learn how to pair correctly, why the bracelet may not turn on and what hidden features become available after you set up correctly. Follow the instructions carefully to avoid common errors that can lead to locking the device.
Initial inspection and charging of the device
Before you try to turn on the Mi Band 3, you need to make sure that there is at least a minimum charge in its battery. Devices stored in warehouses or stores for a long time often run to zero due to the self-discharge of lithium polymer batteries. If you take the tracker out of the box and it is silent, do not panic - most likely it just needs energy.
The charging process Xiaomi Mi Band 3 has its own features, which distinguish it from modern smartphones. The charging cable is a specific connector that you need to remove from the main body of the tracker. Note that removing the capsule module (tracker) from the silicone charging strap is not required, which is a great convenience.
⚠️ Warning: Never try to charge a tracker from Quick Charges or powerful laptop adapters. USB a computer or a weak adapter with a current of no more than 1A, so as not to damage the power controller.
To connect, turn the capsule so that the metal contacts on its back coincide with the contacts on the charging cable. The fixation is due to magnets, but sometimes light pressure is required. The indicator of successful charging is the appearance of the battery icon on the screen or the lighting of the LED indicator (depending on the state of the firmware).
💡
Leave the device on charge for at least 30-40 minutes before the first attempt to turn on, even if the indicator shows full charge at once.
If the screen is still black after 15-20 minutes of charging, try tapping the tracker surface slightly or tapping the touch area. Sometimes the screen only wakes up after receiving a signal from the charger or when abrupt movement occurs.
Installation and configuration of the Mi Fit application
The software is a key element of Xiaomi’s ecosystem, and Mi Fit (now frequently updated and renamed Zepp Life) is the bridge between the tracker and your smartphone, and without it, you can’t turn on and configure the wristband because the menu on the device is so limited.
Download the application should be exclusively from official sources: Google Play Market for Android or App Store for iOS. APK-files from third-party resources can lead to unstable operation, data leakage or inability to authorize the device on the manufacturer's servers.
After installing the application, you need to go through the Mi Account registration procedure, which is a mandatory requirement for working with any Xiaomi smart devices. When registering, specify the correct region, as server availability and data synchronization speed depend on this.
- 📱 Open the application and click “Profile” in the lower menu to log in to your account.
- 🌏 Select your region of residence (usually automatically determined, but it is better to check it out).
- 🔐 Enter your phone number or email to create a new account or login.
- ✅ Confirm the entry through the code from SMS or emails.
Importantly, the app requests a lot of permissions to access phone features. To work properly, the Mi Band 3 must allow access to geolocation (Bluetooth Low Energy requires this in Android), notifications and the background of the app. Without these permissions, the bracelet will permanently lose touch with the smartphone.
Interconnection of the bracelet with a smartphone
The most important step is to directly enable and pair. Unlike conventional Bluetooth headsets, the Xiaomi Mi Band 3 does not need to be searched through the standard Bluetooth menu in the phone settings. If you try to connect it as a normal headset, the connection will likely not install or will not work properly.
The pairing process takes place exclusively within the Mi Fit app. Make sure that Bluetooth on your smartphone is activated and geolocation is enabled. Get closer to the bracelet, preferably no more than 1-2 meters away to eliminate interference from other devices.
In the app, go to the Profile tab, then select Add Device and search for Mi Band 3. Search will begin after selection. When the app detects the tracker, the device image and confirmation request will appear on the smartphone screen. The bracelet itself may also display a vibration or Bluetooth icon requiring touch confirmation.
⚠️ Warning: If an app makes an error or the process freezes while searching, don’t try again. Turn off and turn on Bluetooth on your phone, and reboot the app itself, completely closing it in the background.
Successful activation of the Mi Band 3 is marked by vibration and the appearance of the dial over time. From this point on, the tracker is considered activated and ready to collect data about your activity.
☑️ Checklist of successful pairing
Problem Solving: The bracelet is not turned on
The Xiaomi Mi Band 3 does not respond to charging and touching is not uncommon, most often the problem is oxidation of contacts or deep battery discharge. Metal pads on the back of the capsule and on the charging cable eventually become covered with a layer of oxide or dirt, which prevents the current from passing.
For diagnosis, carefully wipe the contacts with a dry lilaless cloth or cotton swab slightly soaked in alcohol. Make sure the charging cable fits tightly to the body. Sometimes, light swaying of the tracker on the cable during charging to find contact helps.
If visual cleaning didn't help, the device may have gone into deep sleep mode, in which case leave it on charge for a few hours (up to 3-4 hours), even if the indicators don't light up. The power controller may take time to "rock" the battery cell before turning on the screen.
Secret resuscitation method
In rare cases, the problem can be hardware: a failure of the battery or the plume of the display. If after 5-6 hours of charging and all the manipulations, the screen remains black and the phone does not see the device, most likely, a replacement of the battery or the tracker itself is required.
Configuring the interface and functions
Once you have enabled the Mi Band 3, you can see a wide range of settings available through the app, and standard factory settings are rarely suitable for all users, so it is recommended to immediately adapt the device to your needs.
The tracker can vibrate when incoming calls, SMS and messages from social networks (WhatsApp, Telegram, Viber). In the Mi Fit app menu, under "Mi Band 3" -> "Notifications", you can select the specific applications from which notifications you want to see on your wrist.
It's also important to adjust the screen settings. You can choose the time display format (12 or 24 hours), turn on or off the wrist lift to activate the screen, and choose from a variety of dials. Importantly, installing third-party dials through the app can slightly increase battery consumption.
| Function | Description | Impact on the battery |
|---|---|---|
| Wrist lifting | Turning on the screen when raising your hand | High. |
| Sleep monitoring | Analysis of sleep phases at night | Average. |
| Notifications | Vibration of messages | Low. |
| pulsemeter | Continuous or periodic measurement | Medium/High |
Don’t forget to set your goal by steps. It’s 10,000 by default, but you can change that value on your profile to make your motivation more realistic for your lifestyle.
Update firmware and reset settings
For stable operation of Xiaomi Mi Band 3 it is critical to use the current version of firmware. manufacturers regularly release updates that correct synchronization errors, improve sensor accuracy and add new dials.
The Firmware Update process occurs automatically through the app when the bracelet is connected to the smartphone and charged more than 20%. Do not interrupt the upgrade process and hold the smartphone next to the bracelet. Interrupting the data record can lead to the device "brickling".
If the device is not working properly, freezes or does not want to connect, you may need a full reset (Unbind). In the Mi Fit application, you need to select your bracelet, scroll down and press Unbind. After that, the tracker will return to the factory settings, and it can be reconnected as a new device.
💡
Regular firmware updates are the only way to access new features and fix bugs detected after the device leaves the factory.
In some cases, if the software reset doesn't work, you can try resetting through the brast menu itself (if available): find "More" -> "Unbind" (Unbind). This will forcefully break the connection and clear the settings.
