Owners of popular Xiaomi activity trackers often face a situation when the screen displays the wrong time: this can happen after a battery change, moving to a different time zone or software failure.
Modern models like the Mi Smart Band 6, 7 and 8 don’t have a separate button or menu for manual digit input. The logic is built on automatic synchronization with your smartphone via Bluetooth connection. If you notice a discrepancy, you should check the settings of the Mi Fitness or Zepp Life app.
In this article, we will look at all possible causes of desynchronization and propose working solutions: you will learn how to forcefully update data, what to do when changing the time zone, and how to reset the settings to factory if the software glitch does not allow you to change the data in the usual way.
Time synchronization principles in Xiaomi ecosystem
The Chinese brand’s fitness trackers are designed to minimize user interference with basic settings. The main source of accurate time is the smartphone to which the bracelet is connected. The companion app regularly sends a data packet containing the current date, hours, minutes and seconds.
However, for a successful signal transmission, the Bluetooth module on the phone must be active and the application itself not completely closed by the operating system, and in some cases, you need to open the program interface and wait for the connection status update.
It’s important to understand that the gadget itself doesn’t have a built-in GPS module or internet access (except for the rare Pro versions with eSIM, which still prioritize the phone).So if your smartphone is timed down or the wrong region is selected, the bracelet will copy this error.
⚠️ Note: If you travel between time zones, the bracelet may not switch automatically.Make sure the phone has Time Zone Auto-Detection on before connecting the tracker.
A common problem is the aggressive energy saving policy of Android operating systems. The system can “freeze” the background processes of the Mi Fitness application, which does not synchronize for hours, in which case the device screen will display the time of the last successful communication.
Basic setup via Mi Fitness or Zepp Life app
Two main applications are used to manage trackers: Zepp Life (formerly Mi Fit) and Mi Fitness (formerly Xiaomi Wear).The choice of program depends on the model of your device and the year of release. The interface may differ, but the logic of actions remains the same.
The first step is to make sure that the bracelet is paired with the phone. Open the app and go to the main screen where the step statistics are displayed. Usually at the top of the interface is the device icon or connection status. If you see a green indicator, communication is established.
Then you have to do forced synchronization, and you have to pull the app screen down until the update indicator turns up, and then you have to update the time data on the screen, and if you don't, try restarting the phone.
☑️ Checklist of correct synchronization
The profile settings inside the app often hide an important time zone. Go to Profile (or Mine), select your bracelet from the device list, and find Settings. There may be a Time Zone option that you need to manually set if the automation is not working.
Solving problems with desynchronization on Android and iOS
Operating systems manage application access rights differently. iPhone (iOS) problems are less common due to strict background policies, but there are also possible failures. On Android, the diversity of shells (MIUI, HyperOS, OneUI) creates many scenarios of blocking communications.
If time is running out or lagging, check the app's permissions. It must have access to geolocation (to determine the belt), Bluetooth and background work. Without these rights, the data protocol will be interrupted by the system to save battery life.
Xiaomi devices with MIUI or HyperOS shells have built-in battery-discharge protection that often kills the synchronization process. You need to go to your phone's settings, find the Mi Fitness app, and select "No Limits" mode under "Activity Control."
Why can iOS block sync?
Another important aspect is the operating system version: Older versions of iOS (below 13.0) or Android (below 6.0) may not properly handle the new encryption protocols used by the newer bracelet models, in which case only a smartphone software update will help.
Changing the time zone and switching to winter time
Travelers are familiar with the problem of the bracelet continuing to show the time of the city of departure after the flight, because the device does not have its own. GPS-It's a geolocation module that relies on the phone's data, and if the phone switches and the app doesn't, there's a conflict.
Automatic winter or daylight saving time may also be incorrect in some regions, and operators and time servers may be transmitting different signals, and manual adjustments through phone settings are the only way out.
To avoid confusion, follow the following steps immediately after arrival or change of season:
- 🌍 Turn off the automatic time zone determination on the phone.
- ⏰ Manually set the correct time zone in the settings of the smartphone system.
- 🔄 Open the bracelet app and wait for synchronization.
- ✅ Check the result on the tracker screen.
⚠️ Warning: Don’t try to change the time directly from the wristband menu (if there is one option at all).Any changes made to the device itself will be overwritten with data from the smartphone the next time you connect.
Some users note that changing the interface language in the application helps, changing from Russian to English and back again can provoke a re-initialization of the device profile and correct pick-up of the time zone.
Resetting settings and reconnecting the device
If the software methods don't work, the radical but effective way is to reset completely, which will remove all the data from the bracelet and put it back out of the box, and then require re-binding.
To perform the reset, take the bracelet in your hands and find the Settings (cog icon) item in the menu. scroll through the list to the end and select System or Reset immediately (Unbind/Reset). Confirm the action by pressing the touch button. The gadget vibrates and reboots.
After the reboot, it will appear on the screen. QR-It's not just about plugging it back in, it's about first removing the device from the Bluetooth list in your phone settings. Then remove the tracker from the device list inside the Mi Fitness or Zepp Life app.
| Action. | Where to go | The result |
|---|---|---|
| Unbind (Unbind) | In the annex (device profile) | Logical connection break, data is stored |
| Removal from Bluetooth | Phone settings | Complete removal of device drivers |
| Reset (Reset) | Menu of the bracelet | Cleaning memory, returning to factory settings |
| Re-binding | Annex | New synchronization of time and data |
Once installed cleanly and first connected, the bracelet will request permission to access geo-position and contacts, allow all requests to allow synchronization algorithms to work without restrictions, and set the time automatically for 10-15 seconds.
💡
Tip: Before resetting, make sure the bracelet is at least 30% charged so that it doesn’t turn off at the critical moment of flashing configuration.
Updating firmware as a way to eliminate bugs
A common cause of malfunctioning watches is outdated software. Xiaomi engineers regularly release patches that fix synchronization and time server errors. You can check for updates in the device profile.
Go to the app, select your bracelet, and click on Software Version or Update. If a new version is available, a button will appear. The upgrade process requires a stable connection and a battery charge of at least 50%.
When you upgrade, the screen of the bracelet may go out or show the logo. Don't panic or put the phone away. Interrupting the process of writing data into memory can lead to a "brick" device, after which it will be extremely difficult to restore it.
💡
Updating the firmware is not only new dials, but also critical corrections of errors with time zones and Bluetooth protocols.
If the update doesn’t install or the process is stalling, try restarting your smartphone and getting closer to the Wi-Fi router. It’s also recommended to close all unnecessary apps on your phone to free up the resources of the Bluetooth module.
Hardware malfunctions and battery discharge
Sometimes the problem is not the software, but the hardware. The internal battery of the fitness bracelet degrades over time. If the voltage drops below a certain threshold, the device can go into deep sleep, losing the time settings even with a brief shutdown.
Symptoms of a hardware problem include: quick discharge (in 1-2 days), spontaneous shutdowns, resetting time immediately after disconnecting from charging. In such cases, software methods are powerless, and you need to replace the battery or buy a new device.
It's also worth checking the contacts of the charger. Bad contact can cause the bracelet to seem to be charging, but in fact not getting enough current for the time controller to function normally.
In rare cases, there is a defect of the sensor or memory controller, which can not save the configuration file. If the bracelet is new and resets time constantly even after flashing, it is advisable to use the warranty.
