Activation of a new gadget often turns into an unexpected quest, especially when the device does not respond to presses. Owners of Xiaomi fitness trackers often face the fact that the new Xiaomi Mi Band 4 does not show signs of life immediately after being removed from the package.
Before you panic and bring your device to the service, you need to understand the nuances of its initial charging. The right sequence of actions will avoid common errors and save time. In this article, we will look at all the steps, from connecting to the power source to creating an account in the application.
It only takes a few minutes to get the tracker back to working order, and the key is to follow the right technology and use original or certified accessories, and let's take the step-by-step activation process to make sure your bracelet runs smoothly.
Primary charging and battery activation
The most common cause of a new bracelet's non-functioning state is a fully discharged battery. Because lithium polymer cells have the ability to self-discharge when stored for long periods, the device may not respond to the on-screen menu. You need to connect the tracker to the power source.
The Xiaomi Mi Band 4 comes with a special charging cable. Note that the capsule module itself (tracker) needs to be removed from the silicone strap. This should be done carefully, pressing the convex part of the capsule on the back side to push it out of the mount.
Once you remove the module, find two golden contacts on the bottom of the module, which are designed to connect to the magnetic connector of the charger, and it is important to ensure close contact, because oxidation or dust can interfere with current transmission.
⚠️ Warning: If the contacts on the tracker or charger are contaminated, gently wipe them with a dry soft cloth or cotton swab soaked in alcohol!
Connect. USB-cable connector to any standard port USB (computer, laptop or power supply from smartphone power up to 1On the Mi Band screen 4 You should have a lightning icon that signals the start of charging. 5-10 Minutes – sometimes the power controller needs time to wake up».
It takes about 1.5-2 hours to fully charge the device. It is not recommended to leave the tracker on charging for the night for the first time, although modern electronics have protection against overcharging. For initial activation, it is enough to charge the battery up to 80-90%.
💡
Use power supplies from smartphones with currents no greater than 1 Amp (1000 mA). Fast charging with support for QC 3.0 or PD can damage the power controller of the bracelet due to voltage surges.
Installation and configuration of the Mi Fit application
The tracker itself is just an interface for displaying data, all the logic and settings take place in the smartphone. To manage the Xiaomi Mi Band 4, you need to install an official application. At the moment, the main application is Mi Fitness (formerly known as Zepp Life), as the old brand “Mi Fit” is gradually being abolished.
Download software should be exclusively from official stores: Google Play for Android or App Store for iOS. Installation of programs from third-party sources can lead to infection of the device with malicious code or incorrect synchronization.
Once installed, launch the app and create a Xiaomi Account, which is a requirement for the ecosystem to work, and you'll need to enter a phone number or email address, and you'll need to come up with a strong password.
- 📱 Download the Mi Fitness (Zepp Life) app from the official store.
- 📝 Register a new Xiaomi account or sign in to an existing one.
- 🔒 Allow the app to access geolocation and Bluetooth notifications.
- ⚙️ Add the device to your profile by selecting “Profile» → «Add the device».
When you register, carefully fill out your height, weight, date of birth, which are critical to correctly calculating calorie and step flow, and your bracelet algorithms use this data to calibrate your sensors.
Interconnection of the bracelet with a smartphone
Once the app is installed and the account is created, we move to the most important step - pairing. Make sure that the smartphone is Bluetooth enabled. Come closer to the tracker, the distance should not exceed 1-2 meters for a stable connection.
In the app, click the add button. The system will start looking for available gadgets nearby. When the phone screen says "Mi Band 4", click on it. The bracelet will have a request for confirmation of pairing, presented as a vibration signal and icon.
Tap the touch area on the tracker to confirm the action, usually a single touch or finger holding for a few seconds, depending on the firmware version, and once the connection is successful, the data will start to sync.
⚠️ Note: Do not try to connect the bracelet through the standard Bluetooth menu in the Android or iOS phone settings. The pairing must occur strictly through the application interface, otherwise the notification functions will not work.
In some cases, firmware may need to be updated immediately after the first connection, and the application will prompt you to download a new version of the software. Do not interrupt this process and keep the bracelet next to the smartphone until it is completed.
If pairing fails the first time, try restarting your smartphone and repeating the procedure. Also check if the bracelet is connected to another phone - the Xiaomi Mi Band 4 can only be active on one device at a time.

Solving problems with on and charging
There are situations where standard methods don't work and the device still doesn't turn on.If the screen is black and doesn't respond to the charging connection, there may have been a deep discharge or oxidation of the contacts.
Try to leave the tracker on charging for a longer period of time - until 30-40 Sometimes it takes the power controller a while to get the minimum charge to start the system. USB-port or other cable, if possible.
Another reason is contamination of the contacts with sweat or dirt, especially if the bracelet is not new. Careful cleaning of contacts with alcohol often solves the problem.
If nothing works, reset. Some versions of the firmware have a hidden combination or the ability to reset through the app if it sees the device for even a short time. In extreme cases, it may require a battery replacement, which is not economically feasible for the Xiaomi Mi Band 4.
⚠️ Warning: Don't try to open the tracker body yourself. The capsule is sealed tightly to provide water protection. Breaching the seal will deprive you of warranty and protection from water.

If the bracelet doesn’t turn on after 40 minutes of charging and cleaning the contacts, the battery or power controller is likely to fail.
