How to Turn on Xiaomi Mi Band 4: The Complete Launch Guide

The first inclusion of the Xiaomi Mi Band 4 is a process that requires attention to detail, as the device comes in transport mode to save battery power. Many users are faced with the fact that the tracker does not respond to touch immediately after being removed from the box, which is absolutely normal behavior for new electronics.

To successfully launch, you will need not only the bracelet itself, but also a compatible smartphone with an installed application. It is important to understand that without first preparing the mobile device and installing the necessary software, you will not be able to turn on and configure the tracker.

In this guide, we will take a look at all the nuances of launching, from removing the capsule from the strap to solving problems if the screen remains black. Following the action algorithm will avoid common errors and quickly move to using all the functions of a fitness tracker.

Preparation for the first start of the device

Before you try to activate the Mi Band 4, you need to make sure all components are ready to go.The device comes with minimal battery charge, so ignoring the charging stage can lead to a false conclusion about the gadget malfunction.

In parallel with the physical fitness of the gadget, you should prepare the software environment on your smartphone. The tracker requires the Mi Fit application (or its current analogue Zepp Life), which can be downloaded from official app stores. Without this software, the bracelet will remain just a beautiful piece of plastic and metal.

• 📱 Make sure your smartphone has Bluetooth and geolocation enabled (GPS), Because these are mandatory requirements for finding a device.
• 🔋 Check the contacts on the charger – they must be clean and not oxidized to transmit current.
• 💡 Check the tracker screen for protective film, which is often forgotten to be removed before first use.

It’s also worth checking your phone’s operating system version. The Mi Fit app requires Android 4.4 or iOS 9.0 or higher to work properly. If your mobile device is too old, the pairing process may end up in error or not work smoothly.

💡

Before connecting to charging, wipe the metal contacts on the back of the capsule with dry soft cloth to rule out the effect of oxidation on charging speed.

Tracker extraction and physical activation

The main module of Xiaomi Mi Band 4 is enclosed in a silin strap, and to charge it must be removed.This action is often difficult for beginners, as the landing of the capsule is very dense. Don't be afraid to make an effort, but do it carefully so as not to damage the screen or the case.

There's a proven extraction method that minimizes the risk of damage, so flip the strap so that the convex part of the capsule looks down, and push your thumbs down the bottom of the module, pushing it up, and if you're trying to do that with your hands, you can use the edge of the table or a special tool, but with great care.

Once you've removed the module, take a close look at the back of it, and that's where the charging contacts and the pulse sensor are. When you first turn on, it's important to keep the charger in close contact with these areas. If you see any traces of sweat or dirt on the contacts, be sure to remove them before you plug in.

⚠️ Note: Do not use sharp metal objects (knives, scissors) to remove the capsule, as you can easily punch silicone or scratch the screen, which will deprive you of warranty.

Charging process and status indication

Once the module is removed, it must be connected to the charger. Complete with the Mi Band 4 is a special cable, one end of which has a special charger. USB-connector, and the other two pins, insert pins into the recesses at the back of the tracker until you click or fit tightly.

The display on the screen will tell you the state of the device. If the battery has been completely discharged, the screen may not immediately light up. Sometimes you need to wait 5 to 15 minutes before the battery icon appears. This is the normal reaction of a lithium polymer battery at a deep discharge.

• 🔌 If the battery icon doesn’t appear after 15 minutes, check the density of the contacts and try another one. USB-port.
• ⚡ Use a power adapter with a current of no more than 1A so as not to overload the charge controller of the small device.
• 👀 Watch the screen: the appearance of the Mi logo means a successful start of the activation procedure.

While charging, the device can heat up slightly — it's a natural physical process. However, if the heating seems excessive, disconnect the tracker from the mains and let it cool. Full charging takes about 1.5-2 hours, but for the initial turn on, it is enough to 20-30 minutes of work from the mains.

Installation and configuration of the Mi Fit application

While the tracker is charging, install the software on your smartphone. Search the Google Play or App Store for Mi Fit (Developer of Anhui Huami Information Technology) app, which in some regions may be called Zepp Life, which is the same product.

Once installed, launch the app and create an account or log in to an existing one, which is necessary to synchronize data and store your statistics in the cloud. Without registering with Xiaomi accounts, the bracelet’s functionality will be severely limited.

In the main menu of the app, find the add button for a new device, which is usually located at the top of the screen or in the user profile. Select the Mi Band 4 model from the list. The app will ask for permission to use Bluetooth and geolocation - agree with these requests, otherwise it will not be possible to search for the device.

⚠️ Note: Do not attempt to pair the bracelet through the standard Bluetooth menu of your phone settings. The pairing must occur exclusively within the Mi Fit app, otherwise the device may lock for other connections.

When the app goes into search mode, it will start scanning the surrounding space. Make sure the bracelet is near the smartphone (no more than 1-2 meters away). If the search takes too long, try rebooting Bluetooth on the phone.

Interconnection of the bracelet with a smartphone

Once the app detects Mi Band 4, a pairing request will appear on the smartphone screen, while a vibration signal and a graphic symbol resembling a man or a watch will appear on the monitor’s screen, which means waiting for confirmation.

To complete the process, you need to tap the touch button on the wristband, which will confirm that you physically own the device and allow data to be exchanged, and after touching, a message about a successful connection will appear on the phone screen.

• 📲 On the screen of the phone may appear confirmation code – check it with the code on the bracelet, if such an option is active.
• 🔄 Wait for firmware updates: the application will immediately offer to update the firmware tracker to the current version.
• ⌚ Set up the dial: after pairing, you will be able to select the look of the screen from the app gallery.

When you update your firmware, the tracker can reboot several times and the screen can go out. Don't interrupt this process and keep the devices close to each other. Interrupting the update can lead to a software failure that you have to fix with a re-flash.

💡

Successful pairing is only completed when the time on the bracelet is synchronized with the time on the phone, and the main activity scale appears.

Configure the main parameters and interface

After a successful connection, you will see the full functionality of Xiaomi Mi Band 4. The first thing to do is to configure the displayed data. In the application in the "Profile" -> "Mi Band 4" section, you can choose what information will be displayed when you raise your wrist.

You can set up notifications from apps. This is one of the most useful features: the bracelet will vibrate when you receive calls, messages from messengers or emails. In the notification settings menu, tick the boxes against the desired applications, such as WhatsApp, Telegram or calls.

Also in this section, you can set up heart rate monitoring, and you can choose the frequency of your measurements: continuous monitoring consumes more battery, but gives you a complete picture, whereas measuring once every 10 or 30 minutes saves you charge.

Solution: Bracelet not switched on

Sometimes users are faced with a situation where even after charging the Mi Band 4 does not give signs of life, the screen remains black and there is no vibration. In most cases, the problem lies in the "hang" of the controller or deep discharge of the battery.

Try to keep the device on charge for a long period of time, from 1 to 2 hours. If that doesn't work, do a forced reboot. To do this, connect the tracker to the charger, and then quickly press the touch button 5 times in a row. The device should vibrate and show the logo.

• 🔋 If the battery is gone into a deep discharge, leave the tracker on charging overnight, even if the indicator does not burn.
• 🧹 Carefully wipe the contacts with an alcohol napkin to remove the fat film that prevents the charge.
• 📱 Remove the device from the Bluetooth list on your phone and try to find it again in the app.

If none of these methods worked, there may be a hardware malfunction, and you should contact a service center or a vendor, especially if the device is warranty, but 90 percent of the time, you can charge or clean the contacts for a long time.

⚠️ Warning: If the tracker has been in water and stopped turning on, do not charge it immediately.Let it dry completely within 24 hours, otherwise it will short circuit.
