Buying a new fitness tracker is always a surge of enthusiasm, but sometimes unpacking is replaced by bewilderment when the device does not respond to presses. If you are looking for a way to turn on a Xiaomi 4 watch for the first time, it is important to immediately understand one technical detail: this model does not have a physical on button.
Many users mistakenly try to find a hidden touch screen or pinch a single touch area while waiting for the screen to light up.The device is activated solely through a connection to a smartphone, which is the standard for the brand's wearable electronics.
In this article, we will discuss in detail the entire process of preparing, pairing and initial setting of the Mi Band 4. You will learn why the bracelet may not respond to charging and how to install the software correctly for the full operation of the gadget.
Preparation for the first start of the device
Before you try to activate the tracker, you need to make sure that the battery is charged. Often the devices are stored for a long time in warehouses, and the battery manages to discharge to zero. Connect the capsule to the charging cable, after removing it from the silicone strap.
Pay attention to the contacts: they must be clean and dry. If you see oxidation or dust, gently wipe them with a dry soft cloth. The battery charging indicator should appear on the screen a few seconds after connecting to the device. USB-port.
⚠️ Warning: Do not use powerful fast-charging adapters from smartphones if the cable is not protected. USB-cable to the computer port or power supply with a current of not more than 1A.
To sync, you’ll need a Bluetooth-enabled smartphone. Make sure the phone has geolocation (GPS) enabled, as current versions of Android require this permission to work with Bluetooth devices.
Also check your phone's operating system version. The Mi Fit (or Xiaomi Wear) app requires Android 5.0/IOS 10.0 and higher to run smoothly. Older versions of the OS may not support the necessary encryption protocols.
Installation and configuration of the Mi Fit application
A key element of Xiaomi’s ecosystem is its branded app, without which the bracelet is just a piece of plastic with a screen, and you need to download the official Mi Fit app from the Google Play Store or Apple App Store.
Once installed, start the program and create a new account or sign in to an existing one. Registration is mandatory, as all health and activity data will be synced with the Xiaomi Cloud.
During the registration process, the app will request a number of permissions, and it is critical not to ignore requests for Bluetooth access, notifications and background, otherwise the tracker will not be able to transmit data or vibrate when incoming calls.
- 📱 Allow notifications to be accessed to see messages from messengers on your wrist.
- 📍 Enable geolocation for correct tracking of jogging routes.
- 🔔 Give permission to work in the background so that the application is not closed by the system.
In some cases, Android can aggressively close the background processes. Go to your phone's settings, find the Mi Fit app in the list of programs, and select the "No Limits" or "Out-Start" option.
The process of pairing the bracelet with a smartphone
Now, the most important thing is that you connect devices, and unlike Bluetooth gadgets, you can't just choose the device in your phone settings, and you can pair it through the application interface.
Open the app and go to the user profile. Click on the Add Device icon (usually a plus in the corner or a separate button). From the list of available devices, select Mi Smart Band 4.
The app will start searching, and at that point, the bracelet screen may have a vibration or an animation of the wait, and once the phone detects the tracker, a request for confirmation of pairing will appear on the smartphone screen.
☑️ Pre-conjugation check
Once confirmed on your phone, the bracelet will have a digital code on its screen, check it against the code on your smartphone screen, and if the numbers match, confirm the action on the tracker (touch the screen) and in the app.
⚠️ Warning: If the bracelet requests firmware updates during pairing, be sure to wait for it to be completed.
Possible problems with activation
Sometimes it doesn't go as planned. If the bracelet doesn't turn on or isn't visible to the phone, there can be several reasons, and the first and most common is a deep battery drain.
If the charging indicator does not light up, try it. USB-port or cable. Also, it is necessary to carefully clean the contacts on the capsule itself and on the charger with an alcohol napkin.
The second reason is the Bluetooth version conflict: Make sure that the smartphone does not have another Xiaomi device that can intercept the signal, in which case a complete reset of the Bluetooth connection in the phone settings helps.
What do I do if the bracelet is frozen?
The third problem is the outdated version of the app. Go to the app store and check for updates for Mi Fit. Older versions may not support new communication protocols.
Configure the interface and functions after enabling
Once you've successfully enabled and paired, you'll have a world of settings, and the first thing you need to do is set up a dial, and you'll have a dial store available in the app where you can choose the style, color and layout of the elements.
Next, configure notifications, you can choose which apps will duplicate messages on your wrist, which is convenient for messengers, but redundant notifications can quickly drain the battery.
An important function is to adjust the pulsemeter, you can choose to keep monitoring or periodic (e.g., every 10 minutes), and constant monitoring gives you more accurate statistics, but reduces battery life.
| Function | Description | Impact on the battery |
|---|---|---|
| pulsemeter | Measurement of heart rate | High. |
| Notifications | Vibration on calls/SMS | Average. |
| Wrist lifting | Turning on the screen when moving | Low. |
| NFC (Chinese version) | Payment and access | Low. |
Don't forget to set your target in steps and alarm clock, and the vibration of the alarm clock on your wrist is softer than the sound of your phone, and it doesn't bother anyone around you.
Device care and extension of service life
For Xiaomi Mi Band 4 to last, it needs to be properly taken care of. Despite the protection from water, it is not recommended to immerse the device in hot water or steam, as this can damage the adhesive layer of the screen.
Rub the pulse sensor on the back regularly. Dirt and sweat can distort readings or irritate the skin. Use soft tissue without pile.
💡
Remove the bracelet overnight if you do not use sleep monitoring to allow your skin to “breathe” and avoid allergic reactions to the strap material.
For long-term storage (more than a month), keep the battery at 50-60%. Fully charged or fully discharged lithium polymer battery degrades faster.
Avoid hitting hard surfaces. The tracker screen, although covered with protective glass, is sensitive to spot impacts that can lead to cracks.
💡
Regular cleaning of contacts and sensors is the key to stable operation and accurate health indications.
