Owning a fitness tracker involves constant monitoring of activity, but without the correct time, the device loses half of its functionality. If you are wondering how to change the time on Xiaomi Mi Band 3, then we hasten to reassure you: this gadget does not have its own interface for manually entering hours and minutes through the screen.
All the magic happens automatically, but only when connected to the smartphone correctly, and synchronization occurs in the background, transmitting time zone and exact time data from the application servers, but sometimes users are faced with the numbers on the display lagging behind or showing completely incorrect values.
In this article, we will take a closer look at the Mi Fit and Zepp Life architecture, explain the reasons for desynchronization, and offer proven methods to solve the problem, learn how to manage display formats and understand why simply restarting Bluetooth is sometimes not enough.
The principle of synchronization of time
Fundamentally important to understand, the Xiaomi Mi Band 3 acts as a slave device, not storing time on its own for an extended period without recharging, but relying on periodic status updates from the phone. The BLE (Bluetooth Low Energy) protocol provides data packets, including the current time, date and alarm settings.
When you open a companion app on your smartphone, the handshakes occur, at which point the app algorithm checks the phone's system time against the time recorded in the tracker's memory, and if there is a discrepancy, even a few seconds, the bracelet screen is forced to update the data.
⚠️ Warning: If your smartphone is running the wrong time or the wrong time zone is selected, the bracelet will copy this error.
The upgrade process can take anywhere from one to five seconds, during which time the tracker screen may flash or remain black.Bluetooth communication interruption during the time stamp transmission can cause seconds to go wrong, although the clock will remain correct.
💡
The Mi Band 3 bracelet does not have a built-in real-time module (RTC) with long-term autonomy, so it depends entirely on communication with the smartphone for the correct running of the clock.
Basic setup through the Zepp Life app
Traditionally, Mi Fit, which is now rebranded as Zepp Life, is the main tool for changing any settings, including time stamps, and you need to make sure you have the latest version of the app installed from the official Google Play store or App Store.
The process of initial setup or forced synchronization is as follows:
- 📱 Open the Zepp Life app on your smartphone and make sure Bluetooth is enabled.
- 🔗 Go to the device profile by clicking on the Mi Band 3 icon at the top of the screen.
- 🔄 Pull the list down for forced data updates (top-down swipe).
- ⏱ Wait for the notification of successful synchronization and check the screen bracelet.
Sometimes you need a deeper interaction, go to the tracker profile settings inside the app, and you can find the bracelet settings or the time format, and that's where you solve the 12-hour or 24-hour format, which is often confusing for users.
☑️ Connection check
Problems with the format of 12 and 24 hours
One of the most common reasons why users are looking for a way to change time to Xiaomi Mi Band 3, It's not in the watch itself, it's in the way it's displayed. 24-hourly cycle, while by default or due to region settings in the application may be activated 12-clock-format AM/PM.
To change this setting, you will need to do the following:
- Open the Zepp Life (or Mi Fit) app.
- Go to Profile > Mi Band 3.
- Find the Time Format (Time Format) item.
- Switch the switch between 12 hours and 24 hours.
If the switch is not instantaneous, try to close the application completely (unload from memory) and run it again. In some versions of the firmware, changing the format requires rebooting the tracker itself.
Why is AM/PM being shot down?
Changing time zones and traveling
For travelers, the issue of automatic time change is relevant. Xiaomi Mi Band 3 is not equipped with GPS-It's a module, so it can't determine the change in geographic location by itself.
When you arrive in another country, your phone (when you turn on the "Time and Time Zone Auto-Setting" option) receives data from the cellular network, but the bracelet may not update instantly.
| Action. | Smartphone reaction | Reactions of Mi Band 3 |
|---|---|---|
| Arriving in a new country | Time change through the operator's network | Time doesn't change. |
| Opening of the Zepp app | Synchronization of system time | Receiving the data packet |
| Forced synchronization | Transfer of new settings | Screen update (seconds) |
| Rebooting Bluetooth | Reconnecting the device | Reconciliation of time |
If the automatic change hasn't occurred, check the date and time settings in the Zepp Life app itself.There may be a separate Time Zone switch that sometimes conflicts with Android or iOS system settings.
Elimination of outsynchronization and errors
There are times when the time on the bracelet just floats — it starts to lag by a few minutes a day or shows yesterday of the week — this indicates a software failure in the work of the microcontroller tracker or errors in the cache of the application.
The first step should always be to completely reboot the ligament. Turn off Bluetooth on your phone, turn it on again. If that doesn't work, do the following:
- 🔌 Connect the bracelet to the charger (sometimes low charge affects work). RTC).
- 🗑 In the app, select Unpair, but don’t remove the device from your phone’s Bluetooth settings.
- 🔄 Re-search and pair devices through the application.
⚠️ Warning: When uncoupling the device, the current day activity history may not sync. Make sure the data has been uploaded to the cloud before the connection breaks.
If the problem persists, try clearing the Zepp Life app cache in your Android settings (Settings -> Apps -> Zepp Life -> Memory -> Clear cache).This won't delete your accounts, but will reset temporary files that may have caused the sync conflict.
Reset to factory settings
In extreme cases, when software methods do not help and time continues to reset at 00:00 immediately after disconnecting from the phone, a complete reset is required.This action will return the Mi Band 3 to the state it was in at the time of purchase.
To perform the discharge:
- Go to the bracelet settings in the application.
- Scroll down to Break the link or Reset.
- Confirm the action. The bracelet vibrates and resets.
- Re-interconnect as if with a new device.
Once reset, the device will request permission to access notifications and time. Be sure to provide all the permissions requested, otherwise background synchronization will not work and time will start to lag again.
💡
After resetting, wait 5-10 minutes before an active check. The bracelet needs time to initial calibrate and load all the dials.
