Many users who first purchase wearable electronics from the Chinese giant face an unexpected surprise: the device just removed from the box does not respond to touch and looks completely “dead.” This is normal, since the new gadget comes from the factory in a special transport mode to save battery power. To wake up the Xiaomi Mi Band 4, you need to perform a series of simple actions that do not require deep technical knowledge, but are necessary for the correct operation of the device.
The activation process is inextricably linked to the preparation of the smartphone, because the tracker itself does not have a full operating system for offline setting. You will need a modern phone with Bluetooth support and Internet access. It is important to understand that without first installing special software on the phone to launch the bracelet will not work, even if it is fully charged.
In this article, we will go into detail all the steps, from removing the capsule to synchronizing the first steps, and we will also look at the typical errors that can occur when trying to activate the device and how to fix them. Follow the instructions consistently to avoid connection problems.
Preparation for the first launch and inspection of the completeness
Before you try to turn on a fitness bracelet, make sure you have everything you need on hand. In the standard box, in addition to the tracker itself (capsule), there is a strap and a charger. The capsule is the main module containing the battery, display and sensors, and it is necessary to remove it from the silicone charging belt if the charge level is low.
To successfully activate, you will need a smartphone with Android 4.4 or iOS 9.0 and higher. Also critical is stable Internet access, since the initial setup requires downloading profiles and updating the firmware. Make sure that the phone is enabled Bluetooth module, without which communication with the tracker is impossible.
⚠️ Warning: Do not attempt to turn on the device if the battery indicator shows a critically low charge level (less than 5.
Check the integrity of the contacts on the bottom of the capsule. Oxidation or contamination can prevent charging. Wipe the contacts with dry soft cloth if you notice traces of dust or moisture. Clean connections ensure fast transfer of energy and data.
Charging the device before activation
Although the storage units are partially charged, during transportation and storage, the lithium polymer battery could have run out of charge. So the first step is to connect to the power source. Remove the capsule from the strap, gently pressing the convex part on one side and pulling the module out of the socket.
Insert the capsule into the charger so that the golden contacts match. The indicator on the tracker screen should light up, signaling the beginning of the process. If the screen does not catch fire, try to slightly move the capsule in the connector or wipe the contacts with an alcohol napkin.
- 🔌 Use an original charger or a quality charger USB-port of the computer to avoid voltage surges.
- ⏱ Leave the device on charge at least for 15-20 minutes before the first attempt to turn on, even if the indicator lit immediately.
- 💡 Make sure the contacts on the charger are not bent and fit tightly to the areas on the bracelet.
Full charging before first use is optional, but desirable for calibrating the power controller.The current charge controllers in the Mi Band 4 are smart enough to stop the process when reaching 100%, but it's best not to leave the device unattended for the night for the first time.
Installation and configuration of the Mi Fit application
The most common mistake of beginners is to try to connect the bracelet through the standard Bluetooth menu of the phone settings. This is absolutely impossible: the device will not dispose and transmit data.
Download the official Mi Fit app (or its new Zepp Life analogue) from the Google Play Market or Apple App Store. Make sure you download the original Xiaomi app, not third-party clones that may contain malicious code or mishandle data protocols.
💡
It is recommended to download the application only from official stores (Google Play, App Store) to avoid installing modified versions with ads or viruses.
Once installed, launch the app and create a Mi Account, a cloud-based service that will store your activity history, dial settings and health data, and without registration, you can't log in and pair devices.
When you register, you can include real-life data: height, weight, date of birth, which algorithms need to calculate calorie expenditure correctly and analyze sleep quality, and then you can change this data in your profile settings.
The process of pairing and activating the tracker
After registering in the application, go to the Profile tab and select Add Device. In the list of available gadgets, find Mi Band 4. The application will request permission to use Bluetooth and geolocation - be sure to agree, otherwise the search for the device will not begin.
Put the charged tracker next to your smartphone (no more than 1-2 meters away). Press the Search button in the app. When the bracelet and its ID appear on your phone screen, click on it to pair.
☑️ Checklist of successful pairing
The tracker screen and the smartphone screen should show the same confirmation codes. Press the button on the bracelet (touch the touch area) or confirm the action on the phone to complete the bundle.
⚠️ Attention: If the app requires you to update the bracelet firmware during pairing, be sure to agree. Don't interrupt the update process, keep the devices close to each other.
Successful pairing means the tracker is activated and ready to go, and it will now automatically connect to the phone as it approaches, transmitting steps, pulse and notifications in the background.
Configure the main functions and dials
Once turned on, you'll see a world of personalization, and the first thing you should do is pick a dial that's right, and there's a dial store available in the app, where you can download thousands of options, from classic watches to animated images.
Go to the device settings in the app and select "Dials." Choose your favorite style and click "Install." The process will take a few seconds, after which the new design will appear on the bracelet screen.
| Function | Description | Where to set up |
|---|---|---|
| Target number of steps | Daily activity rate | Profile → Goals |
| Reminders | Vibrosignal in a sedentary lifestyle | Profile → Reminders |
| Alarm clock | Vibrational call at a given time | Profile → Alarm clock |
| pulsemeter | Automatic measurement intervals | Profile → Pulse |
Don't forget to set up notifications from social networks and instant messengers. In the "App Notifications" section, select the programs that you want to see messages from on your wrist, which will keep your phone from getting out of your pocket every five minutes.
Hidden features of Mi Band 4
Solution: bracelet not switched on or not connected
Sometimes users are faced with a situation where the tracker does not respond to charging or the phone does not see it. Most often the problem lies in a software failure or oxidation of the contacts. Try to restart the device by putting it on charging for 10-15 minutes.
If the bracelet is on blue when charging but not turning on, firmware may have failed, which is where the touch button is held for a long time (about 10-15 seconds) or the application is paired again after it has been completely discharged.
- 📱 Reboot your smartphone and turn on Bluetooth again if the device search does not give results.
- 🔋 Leave the bracelet on the charger 1-2 Even if the indicator does not immediately light up.
- 🔄 Remove the device from the Bluetooth list in your phone’s settings and try to re-cook through the app.
In rare cases, the problem may be a hardware malfunction of the charging module or battery, and if none of the software methods worked, you should contact the service center or the seller.
💡
90% of the problems with the switching on are solved by careful cleaning of the contacts of the charger and long (more than 30 minutes) charging of the fully discharged bracelet.
