Modern wearables have become an integral part of our lives, helping to track activity, pulse and, of course, time. However, users often face a situation where the Smart Band screen displays an incorrect time zone or time lags. This can disrupt the rhythm of the day and cause confusion, especially if you rely on vibration alarms of the device. Fortunately, the architecture of the Xiaomi trackers is built in such a way that manual setting of the dial on the bracelet itself is not required – everything is done through a smartphone.
The basic principle of the work is to fully sync with the mobile device. Fitness bracelet does not have its own GPS or GSM modules (in most models), so it receives accurate time data exclusively through a Bluetooth connection. If your phone is set correctly and the wrist shows different, then communication is broken or settings are lost in the companion application. It is important to understand that the stand-alone setting of the watch on the device is impossible due to the lack of a full input interface.
In this article, we will discuss the algorithm of actions for all current models, including the Mi Band 4, 5, 6, 7, 8 and earlier. We will look at the work in the official applications Mi Fitness (formerly Zepp Life) and Mi Fit, and also touch on the nuances of using third-party software. You will learn how to forcefully update data, change the display format and what to do if the gadget “refuses” to adapt to the phone.
The principle of synchronizing time with the phone
The fundamental feature of Xiaomi's ecosystem is that it has centralized control of parameters: Time, date, day of the week, and even calendar events are transmitted from your smartphone to the tracker at the time of connection. When you open the app and it successfully connects to the device, there is an automatic exchange of data packets, at which point the watch on the wristband is reset and reset according to the system time of the phone.
If you're in the network, the phone automatically receives the exact time from the cellular operator or over the Internet (NTP protocol). This data is then transmitted to the wearable device. The Bluetooth connection in this case is only a channel, not a time source, which means that if the phone is incorrectly time zoned or automatic synchronization is turned off, the bracelet will display the same erroneous data.
Why can time float?
It's worth noting that the update process doesn't happen every second, it's an active session, so if you've translated the hands on your phone but you haven't opened the tracker app, the changes on your wrist may not be instantly visible, so you need to initiate the connection manually to update the data.
Configure with Mi Fitness (Zepp Life)
For most users, the main management tool is the Mi Fitness app (also known as Zepp Life in some regions), which is where you first link your device and set up all the settings. Before you start, make sure you have the latest version of the program installed from Google Play or the App Store, as old versions may have sync errors.
The time setting process here is as automated as possible. You don't have to search for individual sliders or clock dials, just log in to your account and wait for the green connection icon next to your bracelet image to appear, and once the status changes to Connected, the system automatically sends the data packet with the current time.
- 📱 Open the Mi Fitness app and make sure the bracelet shows up as an active device.
- 🔄 Pull the screen down for forced data updates (fresh pull-to-refresh).
- ⏱ Go to Profile or Device to check synchronization status.
- 🌐 Make sure that the phone settings include an automatic date and time.
In the profile menu, you can often find the “Time Format” item, where you can force the 24-hour format if the phone uses a 12-hour one, or vice versa.
If automatic synchronization does not occur, try restarting the application by closing it completely in Task Manager.Sometimes Android background services block the connection, and you need to restart the program to initiate data exchange with the wearable device.
Using the Mi Fit application for synchronization
Although the brand is gradually moving to a new app, many users still use the classic Mi Fit. The logic is similar here, but the interface may differ. To work correctly, you need to allow all the necessary permissions in the phone settings for the Mi Fit application, including access to location and work in the background.
Inside the app, go to the Profile tab, select your bracelet from the list of devices. This shows basic information about the charge and the last sync. If the time on the bracelet is incorrect, first of all check if the account is not out of sync. Signing out and re-entering often solves problems with sticking old settings.
⚠️ Note: If you use third-party dials downloaded from the store inside the app, they may have their own time display settings. Make sure the dial you choose supports second display or 24-hour format if you need it.
Mi Fit also offers notification and alarm settings that are directly dependent on system time, so if the device is downed, the alarm clocks may not work at the right time, so checking the connection regularly through this application is critical for all the functions of the tracker to work correctly.
☑️ Checking the Mi Fit settings
Solving problems with lagging or wrong time
When the bracelet is behind by a few minutes or hours, it is one of the most common complaints, most often due to the aggressive policy of energy saving of the smartphone operating system. Android and iOS can limit the background activity of applications, considering them “heavy”, which leads to a break in the connection with the tracker.
To solve this problem, you need to add a companion app to battery exclusions. On Xiaomi phones, this is done through the Battery menu → Apps → App selection → No restrictions. On other devices, the algorithm may differ, but the essence is the same: allow the application to run constantly.
| Problem. | Probable cause | Method of decision |
|---|---|---|
| Time is 1-2 hours behind | Wrong time zone on the phone | Enable “Autodetermination” in date settings |
| Time is not updated by the day | Background blocking | Remove battery restrictions for the application |
| Format is lost (AM/PM) | Conflict of dial settings | Change the dial to the standard |
| Complete desynchronization | The Bluetooth module error | Remove the device and re-tether |
Another reason could be overloading of the tracker itself, although this is rare, in which case a complete reset of the device to factory settings through the application helps, and after resetting, the bracelet will ask you to re-pair the pairing procedure, and the time will be set correctly on the first connection.
💡
If you travel frequently and change time zones, don't rely on automatic switching alone. Open the tracker app immediately after arrival to force the bracelet time update, otherwise the alarm may not go off in the morning.
Setting up the time and date format
Many users prefer a 24-hour time format, while some smartphones or certain regions have a 12-hour time format, which may not be obvious because there may not be a separate “Switch format” button in the main menu.
In most cases, the time format on the Mi Band is tightly tied to the system settings of the smartphone, so if you want to change it, you need to go to the general settings of the phone, find the Date and Time section, and switch the 24-hour switch to the switchboard, and then you need to open the tracker app and wait for synchronization.
However, some custom dials ignore system settings and display the time in their own format. If the standard change of phone settings didn't help, try:
- ⌚ Change the dial to the standard (goes in the memory of the device).
- 📱 Switch the language of the phone system (sometimes this resets regional settings).
- 🔄 Update the bracelet firmware through the application to the latest version.
Also worth mentioning is the date format (DD.MM.GYYYYYYYYYYYYYYYYY or MM.DD.GYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY
Third-party applications and advanced settings
For advanced users who lack the functionality of official apps, there are third-party solutions such as Notify for Mi Band (for Android), which allow you to access hidden tracker settings, including finer time settings, vibration patterns and even install your own dial from scratch.
Using these applications requires Bluetooth connectivity and enhanced access rights, and they can intercept signals from an official application and send their commands to the wristband, allowing for example, to adjust the time mapping to seconds (on models where it is supported software) or to change the behavior of the screen when lifting the wrist.
⚠️ Note: Using third-party software can cause unstable device operation or rapid battery discharge.Be careful when changing the system parameters of the tracker through untested programs.
One of the unique features of third-party apps is the ability to configure time zones for multiple cities at once, which is important for those who work with foreign partners, but for the basic task of keeping the clock running accurately, the official software is usually enough.
💡
Xiaomi’s official apps provide stable time synchronization 99% of the time, and third-party software is only needed for specific customization tasks that are not directly related to clock accuracy.
