How to turn on Xiaomi Mi Band 4 after reset: a step-by-step algorithm

After performing a full Hard Reset, your Xiaomi Mi Band 4 returns to factory status. At this point, the tracker goes into a pairing standby mode and its screen begins to display QR-A code or a welcome message with the brand logo. Many users mistakenly believe that the device has got stuck or turned off, but in fact the gadget is just waiting for a command from the control application to further activate the device.

The initial activation process is radically different from the usual screen activation after the battery is discharged. If you just press the touch button, the bracelet will not react in the usual way, since its software now requires authorization via Bluetooth.

It’s important to understand that the success of the switch on depends not only on the battery charge, but also on the correct sequence of actions in the smartphone menu. Resetting removes all data about previous connections, so old entries in the phone’s Bluetooth menu can interfere with new synchronization. In this article, we will discuss in detail the algorithm of actions that is guaranteed to help start the device.

Preparing the device and smartphone for the first launch

Before you try to turn on the tracker, you need to make sure that both sides of communication - both the gadget and the phone - are ready to go. Charge the Mi Band 4 to at least 20-30%, as the process of initial setting and timing may require more power than usual.

On the smartphone side, the situation is even more critical: you will need a stable Internet connection, since the application must check the relevance of the device profile and possibly suggest a firmware update immediately after you connect. Without access to the network, the process can be delayed or end in an authorization error.

⚠️ Warning: Before starting the procedure, be sure to remove the old device from the Bluetooth list in your phone settings. Having a preserved "Mi Band 4" profile can block the new connection, since the security protocol will not allow you to create duplicate communication.

It’s also worth checking the compatibility of the operating system. Xiaomi Mi Band 4 requires Android 4.4 or iOS 9.0 and higher to work properly. If you’re using a very old OS version, the app may not see the tracker or work with critical errors. Update your smartphone system to the current version before you start setting up.

Installation and configuration of a companion application

The Mi Band 4 has historically been used by Mi Fit, which was later rebranded in Zepp Life. You need to download it from the official Google Play store or App Store, as third-party counterparts may not support full functionality or the initial activation process.

Once you install the app, launch it and log into your Xiaomi account, and if you don't have an account, you'll need to create one by providing an email or phone number, which is a must, because all your health and activity data will be linked to that profile, and you won't be able to activate the bracelet without authorization.

In the app interface, go to the Profile tab (usually the human icon in the lower right corner) and there is the Add Device button. Click on it and select from the list Bracelet -> Mi Band 4. The app will go into search and scan space for Bluetooth signals.

Importantly, in the search process, the app can request permissions to access geolocation and Bluetooth. In modern versions of Android, this is a mandatory requirement for Bluetooth Low Energy (BLE). Allow access to the location, otherwise it will be impossible to find the device technically, even if Bluetooth is turned on.

The process of pairing and activating the bracelet

When the app goes into search mode, hold the bracelet in your hands. If the screen is out, tap the touch button to wake it up. QR-Point your smartphone camera at this code, or wait for the app to automatically detect the device.

Once the Xiaomi Mi Band 4 is found, a pairing request will appear on the smartphone screen, while a vibration signal will appear on the bracelet screen and a request to confirm the action (the tick icon or phone icon).

If the pairing is successful, the bracelet vibrates, and the Mi logo appears on the screen. Then the time and date synchronization process begins. The time is set automatically from the phone, so you don't need to manually adjust it. This is critically important, because without the exact time, alarms and reminders will not work correctly.

Sometimes the process can take longer if the smartphone's background services are aggressively saving energy, in which case the system may temporarily interrupt the connection. Don't panic, just wait for the reconnection. If the error repeats, try restarting the smartphone and starting the procedure again.

Updating the firmware after resetting

Immediately after the switch on and initial synchronization, the application will likely offer a software update, which is standard, since the devices could have been in storage for a long time, and the firmware version may have become obsolete, and the update is necessary to fix bugs and improve the stability of the Bluetooth module.

The process of updating is as follows: the application downloads the data packet, then transmits it to the bracelet. The Mi Band 4 screen will display a percentage progress indicator, at which point you should absolutely not interrupt the connection or move far from the phone.

During the upgrade, the Bluetooth connection is in a special data mode, so signal stability is critical. Keep the phone and bracelet close by, ideally, put them on the table in close proximity to each other.

Configure the main functions and interface

Once you have successfully enabled and updated, you will be faced with the issue of personalization. Xiaomi Mi Band 4 offers flexible settings that are best done immediately while the device is in hand. Through the application, you can select a dial, adjust the order of display of the menu and activate the necessary notifications.

Pay special attention to setting up notifications. Not all apps may be enabled by default. Go to the "Application Notifications" section in your bracelet profile and activate the desired messengers (WhatsApp, Telegram, SMS) to allow you to see incoming messages right on your wrist.

You also need to adjust the wear parameters, so if you're left-handed, you can flip the orientation of the screen in the app so that the wrist lift activates the display correctly, and you can also adjust the sensitivity of the hand lift and the time to the screen quench.

• 🔔 Vibration: Set up the vibration force and turn on Do Not Disturb mode at night so that the bracelet does not wake you up with vibration from notifications.
• ❤️ Pulsemeter: Set the frequency of the pulse measurement. For maximum accuracy of statistics, it is recommended to set the interval of 10 or 30 minutes, but this will increase battery consumption.
• 🌊 Waterproof: Make sure that the water-locking screen is activated in the settings (swimming mode) if you plan to use the bracelet in the pool.

Be sure to check the alarm clock and pomodoro timer if you plan to use them, all of which are synchronized instantly and stored in the device’s memory even after discharge.

Solving Connection and Incorporation Problems

Despite the simplicity of the procedure, there are sometimes technical difficulties, the most common problem is that the bracelet is not turned on or visible to the phone, most often due to a deep battery discharge, and leave the device on charge for at least 30-40 minutes, even if the screen does not respond.

Another common reason is app cached data. If Zepp Life writes "Connection Error" or endlessly searches for a device, try clearing the app's cache in Android settings or reinstalling it completely, sometimes cleaning up the list of Bluetooth devices in the system helps.

⚠️ Warning: If the bracelet heats up during charging or after resetting, disconnect it immediately from the charger.This may indicate a malfunction of the battery or power controller.

In rare cases, cold rebooting of the bracelet itself helps, so you can charge it, wait for the logo to appear, then unload it and reset it. Recycle it 3-4 times, and this can reanimate the hover controller.

💡

Use the original charger or a proven charger USB-Cheap Power Banks often give unstable voltage that can prevent the device from turning on after resetting.

Optimization of work after inclusion

Once you've managed to turn on the Xiaomi Mi Band 4 and set it up, you should think about optimizing. New battery algorithms allow the device to last up to 20 days, but only when properly tuned. Turn off constant heart rate monitoring, if you don't need it for training, this will significantly extend the battery life.

It's also recommended that you sync your data periodically (once a month) by opening the app, which not only stores your statistics, but also calibrates your steps based on your phone's data, and calibration is important for accuracy in calculating distance traveled.

If you plan to use a sleep bracelet, make sure that charging is enough overnight.The sleep monitoring mode also consumes energy, though not as much as constantly searching for a Bluetooth signal when you lose communication with your phone.

• 📉 Savings: Reduce screen brightness to a minimum comfort level, this is one of the most effective ways to save money.
• 📵 Breaking communication: If you leave home without your phone, the bracelet will start vibrating. Turn off the "Breaking connection" option if it annoys you.
• 🔄 Synchronization: Set up automatic time synchronization when connected so that the clock always goes exactly.
