Many smart wristband owners face the unfortunate situation of having the wrong time on the Mi Band screen after another wear or reboot, which is puzzling because the device is positioned as an accurate assistant. In fact, Xiaomi fitness trackers don't initially have a mechanism for manually installing the watch directly through the menu of the gadget itself. The whole logic of the work is built on synchronization with the smartphone, which requires the right initial setup.
Automatic synchronization is a fundamental principle of the Wearables ecosystem. The bracelet receives current time and date data exclusively from the connected phone through a special application. If you notice a discrepancy in the readings, the problem is not a malfunction of the electronics, but a software failure or incorrect settings of the interfaced device, understanding this mechanism will quickly eliminate the error without going to the service center.
In this article, we will discuss in detail the algorithm for correct timing on different models of trackers. You will learn how to forcefully update data, what to do if the time zone is lost, and how to avoid typical pairing errors. Manual setting time directly on the bracelet screen is technically impossible in any model of the Mi Band. All manipulations are performed only through the mobile application interface.
The principle of synchronization of time
Xiaomi fitness trackers are a class of dependent devices that don’t have their own cellular module or independent internet access to get accurate astronomical time. The main source of the time stamp is the user’s smartphone. When connected via Bluetooth Low Energy (BLE), the companion app transmits the phone’s current system settings to the bracelet, a process that occurs automatically with each successful connection.
It is important to understand that the internal clock of the bracelet operates from a small charge that is supported by the main battery. When the device is completely discharged or permanently disconnected, the settings can be reset to factory ones, where the time is often the default (for example, 00:00 or the year of the firmware release). This is the critical moment to re-pair. The data protocol ensures that once the phone and the bracelet find each other, the time stamp will be updated in the background.
There are several scenarios where the automatic mechanism fails, and this could be due to aggressive energy savings in the Android operating system that kills the background processes of the Zepp Life or Mi Fitness application, which simply does not receive a signal to update the time, and problems can occur when changing the time zone, if the phone's settings do not activate the automatic network time determination function.
⚠️ Warning: If you have changed your area of residence or moved to a different time zone, check the time settings on your smartphone first. The bracelet blindly copies data from your phone, so if the phone is not at the right time, the bracelet will also do the same.
For the synchronization mechanism to work smoothly, it is necessary that the companion application has constant access to geolocation and runs in the background. Modern smartphone operating systems often limit background activity to save battery, which can interrupt communication with the tracker. In such cases, it is recommended to add the application to the exclusion list or the battery optimization whitelist.
Preparing a smartphone for pairing
Before you try to set the time, make sure that the smartphone is ready to interact correctly with the tracker. The first step is to install official software. For Xiaomi and Huami devices, two main applications are used: Zepp Life (formerly Mi Fit) and Mi Fitness (formerly Zepp). The choice of application depends on the model of your bracelet. For example, for Mi Band 4, 5, 6, Zepp Life is more often used, whereas new models of the Mi Band 7, 8, 9 series require Mi Fitness.
Once you install the app, you need to check system permissions. Without providing location access (GPS) and Bluetooth, the current versions of Android and iOS simply won't allow the app to scan and connect external devices. It's an operating system security limitation that you can't get around. Go to your phone's settings, find the Apps section, select your bracelet manager, and make sure all the necessary switches are activated.
It is also critical to check the date and time settings on the smartphone itself. Go to Settings → System → Date and Time. Make sure that the "Use Network Time" or "Automatically" option is activated. If the phone is manually set the wrong time, the bracelet syncs with this error, in which case the situation can only be corrected by adjusting the time source on the phone.
☑️ Checking before connection
Don’t forget to update the app to the latest version. Developers regularly release patches that fix connection errors with various smartphone models. The old version of the software may not work correctly with new versions of Android, which leads to loss of sync data. In Google Play stores or the App Store, check for available updates for the device manager.
Step-by-step configuration instructions through the application
The process of setting the time is to pair the device first or second. If the bracelet is new, turn it on and follow the instructions on the screen. If the device has already been used but the time has gone wrong, do the following: Open the app on your smartphone and go to the Profile or Devices tab. Find your bracelet in the list. If the status is not connected, click on it to start the search.
When the phone detects the device, a request for confirmation of pairing (vibration icon or tick) may appear on the bracelet screen. Press it. Once the device is successfully connected, the application automatically initiates data exchange. At this point, the download logo may flash on the tracker screen or the dial may be updated. This is the second when the actual time is recorded from the phone's memory to the bracelet memory.
If automatic synchronization didn’t happen right away, you can try forced upgrades. In the application interface, find the “Sync” button or pull the list of devices down for an update. Make sure the bracelet is in close proximity to the phone (no more than 1-2 meters). Obstacles in the form of walls or metal structures can weaken the Bluetooth signal, interrupting the data packet transmission over time.
| Model bracelet | Recommended annex | Min version of Android | Min version of iOS |
|---|---|---|---|
| Mi Band 3 / 4 | Zepp Life | Android 5.0+ | iOS 10.0+ |
| Mi Band 5 / 6 | Zepp Life / Mi Fitness | Android 6.0+ | iOS 11.0+ |
| Mi Band 7 / 8 | Mi Fitness | Android 6.0+ | iOS 12.0+ |
| Redmi Band | Mi Fitness / Zepp Life | Android 6.0+ | iOS 12.0+ |
Once synchronized successfully, the time on the wristband should change. If that doesn't happen, try rebooting both devices. Turn off Bluetooth on your phone, turn it on again, then reboot the wristband itself through the settings menu (if the model allows) or through the app. Reconnecting often solves the problem of a suspended synchronization service.
What to do if the time is set with a shift?
Solving problems with desynchronization
A situation where time is constantly running away or resetting after the bracelet is turned off from charging can indicate deeper problems. One common cause is a conflict of software versions. If the bracelet has old firmware installed and the application has updated, the synchronization algorithms may not work correctly. In the application, always check the section “Update profile” or “Check updates.” Install the latest available firmware version for your device.
Another important aspect is the work of background services. In smartphones Xiaomi, Huawei, Honor and other brands with aggressive memory optimization, the system can completely close the tracker application if the phone screen is turned off, as a result, the bracelet loses communication and does not receive time updates for days, you need to go to the battery settings and allow the Zepp Life or Mi Fitness app “Sunset” and work in the background without restrictions.
- 🔄 Reboot your smartphone and bracelet – it solves 80% of the software glitches of communication.
- 🗑️ Remove the device from the list of conjugated in the Bluetooth settings of the phone and re-attach via the application.
- 📡 Check if the phone is on Flight mode or energy saving that blocks Bluetooth.
If nothing works, you can try to reset the bracelet completely to factory settings. In the app, find "Untie" or "Reset", confirm the action. After that, the bracelet will be cleaned, and it will need to be connected as a new device. In the initial setting, the time will be set correctly. This method is radical, but effective at persistent errors.
⚠️ Note: When you untie the bracelet in the application, all accumulated training and sleep data that has not yet been synced to the server may be lost.
In rare cases, the problem lies in the Bluetooth module of the phone. Try to connect the bracelet to another smartphone. If the other phone keeps the time perfectly, then the problem is in the settings or hardware of your main phone. If the other device is time lost, there is a possibility of a defect in the tracker itself.
Time zone setting and time format
In addition to the exact time, users are often interested in the format of its display (12 or 24 hours) and time zone. The time format (AM/PM or 24h) is usually inherited from the system settings of the smartphone. To change it, go to the phone Settings → Date and time and select the desired format. After that, synchronize the bracelet. Some dials may ignore this option if they are made by third-party developers and have a rigid format.
Time zones are more complicated. If you're traveling, the bracelet has to automatically adjust to your phone's network. However, if you're in a border area or using a VPN, the phone can detect the wrong region. The Zepp Life and Mi Fitness apps don't have a separate manual time zone setting for the bracelet -- it's always equal to the phone's belt -- so the key to the solution is to get the right location on the smartphone.
For custom dials owners (via the AmazFaces app or Notify for Mi Band), the rules may differ. Third-party dials sometimes have their own time display settings that may conflict with the system. If you have set a beautiful but "glutty" dial, try returning the standard design through the official app to see if the problem persists over time.
💡
Use only standard dials from the official app store if you experience persistent problems with time. Third-party dials may contain errors in the sync code.
