The activation of a new activity tracker is always an exciting moment, marking the beginning of the journey to a healthier lifestyle. Xiaomi Mi Band 3 has established itself as one of the most popular gadgets due to its excellent balance of price and functionality. However, despite the simplicity of the design, many users have difficulties during the initial launch phase, when the screen remains black and the vibration does not make itself felt.
The problem most often is not the breakdown of the electronics, but the banal discharge of the battery after long storage in stock or deep discharge of the lithium polymer battery. Unlike smartphones, there is no "Power" button that can be pinched to force reboot, which confuses inexperienced owners. The right sequence of actions when first turned on is critical for the device to move from storage to active mode.
In this article, we will discuss all the nuances of activating your tracker, we will look at the physical features of connecting to charging, working with the mobile application and diagnostic methods if standard methods do not help.
Preparation for the first launch and inspection of the completeness
Before you try to activate the gadget, you need to make sure that the components are intact and compatible.The Mi Band 3 kit consists of two main parts: the tracker itself (capsule) and the interchangeable strap. Sometimes users try to charge the device without removing the module from the silicone bracelet, which is physically impossible to do correctly due to the design of the charger.
Visually inspect the screen for protective film. Factory film is often matte and can create the illusion of a screen turned off even if it works. Carefully tuck the edge of the protective layer and remove it to gain direct access to the touch surface. Also check the contacts on the back of the capsule: they must be clean, free of oxides or contaminants.
Make sure you have the original charger or quality equivalent on hand. The Xiaomi Mi Band 3 uses a specific charging dock that requires the tracker to be removed from the strap. Using incompatible charges from other models, such as the Mi Band 2 or Mi Band 4, can lead to improper contact or battery damage.
⚠️ Warning: Do not try to charge the tracker inserted into the strap.This will cause the contacts to not close with the charger, and excessive force can damage the silicone or capsule body.
If you have purchased a used device or it has been idle for a long time, the battery can be critical. In such cases, the standard charging procedure can take much longer than usual. Don't panic if the charge indicator does not light up in the first 10-15 minutes - let the battery "swing".
Proper connection to the charger
The most important step, which depends on 90% of success is the correct connection to the power source. There are two metal contacts on the back of the tracker. Xiaomi's charger has convex response parts that should perfectly match the recesses on the bracelet body. With the right connection, you should feel a slight click or a tight fit.
After connecting the capsule to the dock, connect USB-The charging connector to the power adapter of your smartphone or the port of your computer, and the process will show up almost instantly on the screen, unless the battery is completely dead, and you'll see the battery icon with a percentage of charge. If the screen catches fire, half the battle is done, the device is alive and ready to go.
💡
Use it. USB-The port of the computer for the first charge, because the current is weaker, which is safer for deep-discharged batteries.
In rare cases, the contacts may become oxidized or contaminated. Wipe them with a dry lilac cloth or cotton swab slightly soaked in alcohol. Make sure there are no villi or dust between the contacts that can prevent the passage of electric current. Mechanical exposure should be minimal so as not to damage the thin layer of metal.
If after 30 minutes of charging the screen is still black, try to slightly change the angle of the capsule in the charger. Sometimes manufacturing tolerances lead to the contacts not converging the first time. Easy swaying the device in the dock can help find the point of contact, and the screen will light up.
Activation process through the Mi Fit application
The screen itself is not a full-fledged work. All functions require synchronization with a smartphone. The main tool for managing is the Mi Fit application (known as Zepp Life), download it from the official Google Play store or the App Store. Installing software from third-party sources is not recommended due to security risks.
Launch the app and create an account or log in to an existing one. Go to the profile and select "Add device." In the list of available gadgets, find Mi Band 3. The app will request permission to use Bluetooth and geolocation - be sure to agree, otherwise you will not be able to find the device.
☑️ Checklist of successful activation
When the app starts searching, put the bracelet next to your smartphone. The tracker screen may have a pairing request (vibration and Bluetooth icon). Tap the bracelet screen to confirm the action. Once successfully connected, the Xiaomi Mi Band 3 will automatically update the time and date, sync with the phone, and be ready to track the steps.
It is important to note that the Internet connection on the smartphone must be active to set up initially, the application needs to download the device profile and check for firmware updates, and if the software version is outdated, the system will prompt you to update, which cannot be interrupted.
Diagnosis: what to do if the bracelet is not turned on
If you're holding the tracker on charge for more than an hour and the screen is black, you need to do a deep diagnostic. First, check the charging cable and the adapter on the other device to rule out any malfunction.
Try to rock the battery. Leave the device on charge for 2-3 hours, even if there is no reaction. Lithium polymer batteries at deep discharge can take a long time to gain the minimum voltage necessary to start the power controller. Patience in this case is a key factor.
| Symptoms. | Possible cause | Decision |
|---|---|---|
| Black screen, no vibration. | Deep battery discharge | Leave on charging for 2-3 hours |
| Blinking battery icon | Low charge or poor contact | Wipe your contacts, press them tighter. |
| The logo appears and goes out. | Error or weak battery | Try to connect to the PC, update the software |
| Vibration is there, the screen is not on. | Display or plume malfunction | Requires repair or replacement of the module |
There's a software reset method if the device is partially responsive. In the Mi Fit app, try to break the pairing in your phone's Bluetooth settings, then remove the device from the application profile and search again. Sometimes a software conflict interferes with the system starting correctly.
⚠️ Attention: If after 4-5 hours of continuous charging on the original device no signs of life, most likely, the battery failed or there was a break in the internal circuit.
Configure the main functions after inclusion
Once activated successfully, you'll be tasked with fine-tuning your needs. Personalization is what turns a simple step counter into a smart assistant. Go to the device profile in the app and select "Bracelet settings." Here you can change the dial, adjust the time format (12/24 hours) and the units of measurement.
Pay special attention to notifications. Xiaomi Mi Band 3 can display messages from social networks, calls and SMS. In the menu "Application Notifications" activate the desired programs. Remember that to work notifications, the Mi Fit application must work in the background, otherwise the Android system can "kill" it to save energy.
