Owners of the popular fitness tracker often face the need to adjust the time zone or time display format correctly. Xiaomi Mi Band 4 is a device that does not have its own interface for manually entering the date and hour through the touch buttons on the bracelet itself. All the logic of the work is tied to the smartphone, which makes the setup process unique but sometimes challenging for beginners.
The right time is not only necessary to know what time it is, but also to properly monitor sleep and alarm clocks. If the clock on the tracker lags or runs ahead, your activity statistics may be incorrect and notifications are not coming on time. In this article, we will discuss all aspects of synchronization in detail.
The basic principle of the Mi Band 4 is to automatically receive time data from the connected phone. You do not need to manually adjust the hands every day, as in a mechanical watch. However, there are nuances associated with regional settings, 12/24 hour format and possible crashes in the Mi Fit or Xiaomi Wear app that require user intervention.
Time synchronization on Mi Band 4
Fundamentally important to understand is that the Xiaomi Mi Band 4 doesn’t have a built-in GPS module or independent internet access to get accurate atomic time.The device relies entirely on a Bluetooth connection to a smartphone. Once the bracelet connects to the phone, it requests current time and date data, then updates its internal timer.
The synchronization process occurs in the background every time a companion application is launched. If you notice that the time on the tracker screen is lost, the first thing to do is open the application and pull the screen down to force the data to be updated. The Bluetooth connection must be stable, otherwise the update command may not reach the device.
There is also a feature of the operation in the mode of energy saving: if the battery power of the Mi Band 4 is critically low, the device can go into sleep mode and stop supporting a constant connection, which may stop the time to update until the next full charge and synchronization.
⚠️ Warning: If you have changed your time zone (flighted to another country), don't manually change your phone's settings while the bracelet is connected. First turn off Bluetooth, change region on your phone, and then reconnect to avoid time stamp conflict.
Step-by-step: setup via the Mi Fit app
The official Mi Fit app (or its newer Xiaomi Wear) is the main tool for managing your gadget. This is where all the key settings affecting the display of time are located. Before starting the procedure, make sure that your smartphone has access to the Internet to get accurate data from the server.
To start, open the app on your smartphone and go to the Profile tab. From the device list, select your Mi Band 4. Next, you'll need to find the Device Settings or Bracelet Settings section, and you'll find settings that you can't see on the tracker screen.
Find Time Format, the switch will let you choose between 12-hour and 24-hour formats, change immediately after you press, and the bracelet screen will update. If that doesn't happen, try closing the app completely and running it again.
☑️ Checklist of correct synchronization
Importantly, some firmware versions may not have a direct “Set Time” button, as the system involves automatic adjustment. If the time is still incorrect, try changing the time 1 minute ahead, syncing the bracelet, and then returning the exact time on the phone and syncing again.
Setup via the Zepp Life app
As the Xiaomi brand is gradually shifting to the Zepp ecosystem, many users are using the Zepp Life app (formerly known as Mi Fit).The interface here is a little different, but the logic remains the same. Open the app and make sure your Mi Band 4 shows up on the home screen as an active device.
Go to the device profile by tapping the bracelet image. In the settings menu, look for the bracelet settings section. Here you will see the option "12-hour format." If the tick is set, the time will be displayed with the AM/PM designation. If you remove the tick, the usual 24-hour format will turn on.
Zepp Life also allows you to manually adjust your time zone if the automatic detection is not working correctly, which can be useful if you are traveling across time zones and your phone does not have time to switch, but for permanent use in one city, it is better to leave automatic mode.
What to do if the app does not see the bracelet?
Change of time format: 12 or 24 hours
The choice of time format is a matter of taste, but for many users, the 24-hour format is the standard. On the Mi Band 4, this setting is strictly tied to the settings in the companion app. If the bracelet is displayed at 14:00 and you need 2:00 PM, or vice versa, the change is made exclusively by software.
It is worth considering that some dials (dials) can ignore the system settings and display the time in its own format, laid down by the developer of the dial. If you changed the format in the settings, but nothing has changed on the screen, try to install another standard dial from the app gallery.
The format of the time also affects the display of alarm clocks. If you are used to the 24-hour format, but the app is 12-hour, you can accidentally set the alarm for 8 am instead of 8 pm (or vice versa), if you do not pay attention to the AM/PM indicator. So checking the format is an important step in the initial setting.
| Parameter | 12-hour format | 24-hour format | Where to change |
|---|---|---|---|
| Display | 02:00 PM | 14:00 | Appendix Mi Fit/Zepp |
| Use of the | United States, Canada, part of Asia | Europe, Russia, CIS | Bracelet settings |
| Impact on alarm clocks | Requires an AM/PM choice | Direct hour entry | Alarm clock menu |

Problem Solving: Time is lost or not updated
The situation when Mi Band 4 stops showing the actual time, most often associated with software failures in the operating system of the smartphone or the application itself. Android and iOS can aggressively save energy by “killing” the background process of the Mi Fit application, which causes constant time synchronization to stop.
To fix this, you need to go to your phone’s settings, find the Apps section, select Mi Fit or Zepp Life, and select the “No Limits” mode from Battery or Energy Saving, which will allow the app to be permanently in memory and adjust the watch on the wristband regularly.
Another common reason is to desynchronize the system time of the phone itself. if your smartphone has time lost (for example, after retrieval). SIM-If you have a card or reset, the bracelet will also receive incorrect data. Check if the option “Use Network Time” is included in the date and time settings of the smartphone.
⚠️ Warning: Do not try to “flash” the bracelet with third-party utilities to fix the time.This can lead to locking the device (brick), as the Mi Band 4 has protection against unauthorized interference with system files.
💡
Tip: If time is lost immediately after disconnecting from charging, the problem may be the wear and tear of the bracelet's internal battery, which does not hold the charge in deep sleep mode, in which case more frequent recharging will help.
Changing the time zone and traveling
For travelers, the Xiaomi Mi Band 4 offers a convenient automatic local time switching feature. Once your Internet-connected smartphone detects geolocation change and updates its system time, the bracelet will follow suit when it first syncs.
However, if you are in an area without network coverage (for example, in an airplane or roaming without Internet), the phone may not automatically update the time, in which case, before leaving the coverage area, it is recommended to manually set the correct time in the phone settings so that the bracelet syncs with it before losing communication.
When you get home, it's the reverse order, so don't panic if the time jumps at the airport, wait for your Wi-Fi connection, let your phone update, and then open the fitness tracker app for final sync.
💡
Automatic time synchronization works only with an active Bluetooth connection and the working background process of the Mi Fit application on a smartphone.
