Xiaomi’s modern wearables have become the standard in the affordable wearables industry.The Smart Band 8 Active is a lightweight version of the popular tracker focused on basic activity monitoring and long-term autonomy. Users often face difficulties in initial activation, as the device comes with minimal battery life to save its life during storage.
The process of launching the gadget is not limited to a simple push of a button, since this model uses touch control and the absence of physical mechanical switches. To work properly, a number of preparatory steps must be performed, including installing specialized software on the smartphone. Ignoring the pairing steps can lead to the fact that the screen of the device will remain black even if the battery is partially charged.
In this article, we will discuss in detail the algorithm of actions necessary for the successful activation of your new tracker.We will look at the nuances of working with the Mi Fitness application, the features of connecting via Bluetooth and how to eliminate common synchronization errors. Following the instructions will allow you to avoid unnecessary calls to the service center and immediately start using all the functions of the device.
Initial preparation and testing of equipment
Before you try to activate the gadget, you need to make sure that all the components in the box are available. Standard equipment includes the tracker itself, a charging cable with magnetic contacts and a brief instruction. The absence of a charger in some regional versions can be an unpleasant surprise, so check the contents of the package immediately after opening.
Carefully inspect the body of the device for protective film. Factory film often has a bright color or logo that can be mistaken for the screen on. Removing the protective film is a mandatory first step, as it blocks the operation of the touch layer and can create a false impression of a malfunctioning display.
It is also worth assessing the status of the charging contacts on the back of the tracker, which should be clean and dry, and if the contacts show signs of oxidation or contamination, they should be gently wiped with dry soft cloth before connecting to the power source.
⚠️ Warning: Do not use wet wipes or aggressive chemicals to clean contacts, as getting moisture inside the case through process holes can cause irreversible damage to electronics.
Make sure you have a smartphone with Bluetooth 5.0 or higher on hand.While the device is compatible with many operating systems, you will need a stable Internet connection on your mobile device to set up and activate the features initially.
Installation and configuration of the Mi Fitness application
A key element of Xiaomi’s ecosystem is the Mi Fitness app (formerly known as Zepp Life for some models, but the 8 Active requires Mi Fitness). Without this software, the bracelet is simply a screen with a watch that can not transmit health data.
Once installed, you need to register an account or log in through an existing Xiaomi Account profile, which is a security and data synchronization requirement, and when you first log in, the system can request permission to use geolocation and Bluetooth, which are critical for stable connection operation.
The app settings recommend choosing the right region right away. If you are in Russia or CIS countries, choosing the wrong region can limit functionality or lead to errors when registering a device. The application interface is intuitive, but it is important not to miss the stages of granting permissions.
💡
When registering an account, use a real date of birth, as it affects the calculation of heart rate and calories burned in the application algorithms.
The main menu of the app contains the Device tab or the + button to add a new gadget. It is through this interface that the bracelet is searched and (paired) with the phone. Manual search through the standard Bluetooth settings of a smartphone often does not give full access to the functions, so using the application is mandatory.
Charging process before first activation
As mentioned earlier, new devices often come with a discharged battery. Connect a magnetic cable to the contacts on the back of the tracker. Magnets must confidently pull the cable in, making contact. When connected correctly, a battery icon or charge indicator will appear on the device screen.
If the screen remains black even when connected to charging, try to shift the cable slightly to the left or right to find the optimal position of the contacts. Sometimes oxidation or factory lubrication can prevent current from passing in the first seconds. Leave the device to charge for at least 15-20 minutes before trying to turn on.
Use an adapter with a current of no more than 1 Ampere (a standard USB port of a computer or a simple power supply from a smartphone). Using powerful fast charging units from flagship phones is theoretically possible thanks to the power controller, but can cause the device to heat up.
- 🔌 Use only original or certified cables to avoid contact issues.
- 🔋 Do not leave the device unattended overnight on charge for the first time.
- ⚡ Make sure that USB-port, which includes the cable, is serviceable and provides voltage.
While charging, the device can heat up — a normal physical process for lithium polymer batteries — if the heating seems excessive, however, the procedure should be stopped and the cable checked.
☑️ Pre-insertion check
Activation and pairing with a smartphone
Once the device has received enough charge, it should automatically go to standby mode. Go to a smartphone with Bluetooth enabled and launch the Mi Fitness app. Press the add device button and select from the list of Xiaomi Smart Band 8 Active.
The bracelet will display a digital code or pairing confirmation request, and you need to check the code on the tracker screen and in the app, then click "Confirm" or "Accept," which creates a secure encryption key for data transfer.
In some cases, you may need to update your firmware immediately after pairing, and software updates are critical, because the factory version of the firmware may contain bugs that affect sensors or Bluetooth connection stability. Don't interrupt this process.
⚠️ Warning: During the firmware update, keep the bracelet in close proximity to the phone (no more than 1 meter) and do not press any buttons on the tracker screen so as not to disrupt the data recording process.
If automatic search fails, try restarting Bluetooth on your smartphone or restarting the app itself. Sometimes cleaning up the Bluetooth cache in your Android settings helps if you use that operating system.
What to do if the code does not appear?
Configure the main parameters and interface
After successful pairing, you can see the dial settings menu. Xiaomi Smart Band 8 Active supports downloading thousands of different interface designs. The dial choice is not just a matter of aesthetics, but also a way to optimize battery consumption or bring the desired widgets to the forefront.
In the Profile section, you need to put up-to-date data on height, weight and age, which algorithms use to calculate body mass index, calorie expenditure and sleep phase analysis, and incorrect data will lead to incorrect health statistics.
Special attention should be paid to setting up notifications. You can choose which apps will duplicate notifications on the wrist. Excessive notifications can quickly drain the battery and irritate the vibration, so it is recommended to leave only important messengers and calls.
| Parameter | Recommendation | Impact on the battery |
|---|---|---|
| Screen brightness | Auto or 40-50% | High. |
| Pulse rate | Every 10-30 minutes | Average. |
| Wrist lifting | Included (day) | Average. |
| Notifications | Only important. | Low. |
Also available in the settings is the Health section, where you can activate stress monitoring, women's health and blood oxygen levels (SpO2), activating continuous monitoring of these indicators significantly improves data accuracy, but reduces battery life.
Diagnostics of problems and solution of connection errors
Despite the simplicity of the procedure, users may encounter technical difficulties: If the bracelet does not turn on after charging, it may be a problem in the cable or blocking the charging port with dust. USB-port or other power adapter.
Time desynchronization is a common problem. If the time on the bracelet is not the same as the phone, check if the Mi Fitness app is allowed access to geolocation and network time. In Android, it is also important to provide permission to work in the background so that the system does not “kill” the sync process to save energy.
If the sensor is no longer responsive to touch, perform a forced reboot, which requires holding the touch area (or side button, if it is provided in a specific interface modification) for 10-15 seconds before the appearance of the Xiaomi logo.
- 🔄 Reboot often solves 90% of software failures and interface freezes.
- 📱 Removing and reinstalling the Mi Fitness app helps to reset cache errors.
- 🔗 «Forgetting the device in Bluetooth settings and re-pairing eliminates key conflicts.
In case none of the methods helps, and the device does not show signs of life for more than 30 minutes on charging, it is possible that there is a production defect of the battery.
💡
Most of the problems with the inclusion and connection of Xiaomi Smart Band 8 Active are solved by completely discharging the device (up to 0%) followed by a long-term charging with the original cable and reinstallation of the Mi Fitness application.
