Modern wearables like the Xiaomi Mi Band 4 have become an integral part of many health-conscious users’ lives. However, even such advanced gadgets sometimes face technical accidents when the screen displays the wrong time or date. This is not just an inconvenience, but a serious obstacle to proper tracking of activity and sleep. In this article, we will examine all the nuances of time zone synchronization and elimination of display errors.
It is important to understand that the fitness bracelet itself does not have a built-in GPS-You have a module or a permanent Internet connection to adjust your time, and all the information comes from your smartphone via a Bluetooth connection, and if you see a discrepancy, it means that the communication between the devices is broken or the settings in the application are down. Let’s figure out how to get your watch back accurate.
To start with, the customization process doesn't require any deep technical knowledge, just follow the algorithm described below, and we'll look at both standard methods through official applications, and how to solve problems when time flies back in time or shows the time zone of another region, and the right setup ensures that all your sports achievements are accurate.
The basic principle of time synchronization
The key to Mi Band 4 is smartphone dependency, which takes the current time, date and time zone directly from your phone system, which means that if your Android or iPhone time is incorrect, it will be displayed on your wrist with an error, so initial diagnosis always starts with checking the settings of the phone itself.
The data transfer process is automatic when you connect the tracker to the application. You don't have to manually set the watch on the wristband itself, there's no such function in the device interface. All control is done through the software interface. When you synchronize successfully, the data is updated instantly, and the arrows (or numbers) on the screen take their correct positions.
There are several scenarios where manual intervention may be required:
- 📱 You changed your smartphone or moved it. SIM-map to device with different time zone.
- 🔄 There was a failure in the Bluetooth module, and automatic synchronization was not.
- ⚙️ You reinstall your companion app or update your bracelet firmware.
- 🌍 You are traveling and are in a different region where time is different from home.
It's worth noting that the time zone is not just time-based, but geolocation-based if it's on, but the main reference point for the bracelet is the phone's system time. If you're traveling, make sure that the smartphone has the option of "Auto-Tune Time Over Network" enabled, which will save you from having to reconfigure the gadget every time you cross borders.
💡
Always keep the Mi Fit or Zepp Life app running in the background so that time synchronization happens automatically with each Bluetooth connection.
Configure via the Mi Fit app
The official and most stable way to set up is to use the Mi Fit app (or its new name Zepp Life), which acts as a bridge between the phone's operating system and the bracelet's microcontroller. To set up, make sure the bracelet is charged and in close proximity to the phone.
Once you open the app and connect the device, the system will check the data itself, and if you notice a discrepancy, do the following: First, go to the device profile, usually the bracelet icon at the bottom of the screen or in the Profile section, and you need to find the sync point or just pull the screen down to update the data.
In some cases, deeper setup is required. Go to your phone's settings, find the Bluetooth partition, select your Xiaomi Mi Band 4 and click "Forget the device" or "Unpair the pairing." Then pair again through the app, which will force the data exchange process, including the correct time.
☑️ Checking the time setting
It's important to monitor the app's permissions. To work properly, Mi Fit must have access to geolocation and system time. Without these permissions, the app may not be able to read the time zone and transfer it to a wearable device. Check your smartphone's privacy settings in the app section.
⚠️ Warning: If the bracelet time is still lost after reconnecting, try restarting the smartphone itself. Often, system time services in Android or iOS can freeze, and a simple reboot solves the data transfer problem.
Use of the Zepp Life App
As the Xiaomi brand is gradually moving users to the Zepp ecosystem, Mi Fit is now often offered to upgrade or replace with Zepp Life. There is no fundamental difference in timing between the two versions of the software, but the interface may differ. The logic remains the same: the phone dictates the conditions, the bracelet obeys.
When Zepp Life first starts, the app will request permission to access the location, which is critical to determining the correct time zone. If you deny access, the app can use standard GMT time or manually set time on the phone, which can lead to errors when switching to daylight saving time.
For forced synchronization in Zepp Life:
- Open the Profile tab in the lower right corner.
- Select “My Devices” and find your bracelet.
- Click the data update button or simply log in to the device menu.
- Wait until the synchronization process is complete.
If you use two phones (for example, personal and work), remember that the bracelet syncs with only one active device. The time will correspond to the phone with which the last communication was made.
Why does time go wrong after turning off Bluetooth?
The problem of resetting time during discharge
One of the frequent complaints of users is the time reset to 00:00 or the date on 01.01.2019 after the battery is completely discharged. This is normal behavior for electronics of this class if the internal memory buffer loses power. However, if the bracelet is not completely discharged and time is still reset, this may indicate battery wear or software glitch.
To avoid losing settings, try not to bring the device to a state of deep discharge. Lithium polymer batteries used in the Mi Band 4, it is better to keep the internal clock running with real time residual charge. If you plan to not use the bracelet for a long time, charge it to at least 50-60% before storing.
The following table shows the symptoms and their possible causes related to nutrition and time:
| Symptoms. | Probable cause | Decision |
|---|---|---|
| Time resets at 00:00. | Full battery discharge | Put it on charge and synchronize |
| 1-2 hours behind | Wrong time zone on the phone | Check the date and time settings in the OS |
| Date is displayed incorrectly | Calendar synchronization error | Reconnect the device in the application |
| Time "floats" during the day | Unstable quartz work | Update the bracelet firmware |
If the bracelet battery holds the charge well, but the time is reset with each charge, then perhaps the problem in firmware, in which case the update of the firmware through the application will help, sometimes manufacturers release patches that fix the power controller and timer.
Update the firmware to eliminate errors
Xiaomi Mi Band 4 software is updated periodically. Developers fix bugs, improve the stability of Bluetooth connections and optimize the work with new versions of Android and iOS. If you have persistently (constantly) run out of time, first check for updates.
To update, go to the Mi Fit/Zepp Life app, select your bracelet, and find “Update Check” or “Update Software.” The process takes a few minutes, while keeping the bracelet close to your phone and avoid opening other heavy apps to keep the data transfers running.
It is important to understand that during the update, the firmware is overwritten completely. This can take up to 5-10 minutes. The bracelet can vibrate and show progress bar. Interrupting the process can cause the device to stop turning on, so make sure that the bracelet charge is at least 20%.
⚠️ Warning: Do not try to update the firmware if the charge level of the bracelet is critically low.This can lead to the "bricking" of the device, after which it will be possible to restore it only in the service center.
Once the bracelet is successfully updated, it will automatically restart, at which point all parameters, including time, date, alarm clocks and step goals, will be fully synchronized, and usually, after updating, the problem with running time is solved dramatically.
Bluetooth Diagnostics and Resetting Settings
If the software methods don't work, maybe the problem lies in the communication protocol itself. Bluetooth modules can accumulate errors in the cache. In this case, a complete pairing reset is effective. Remove the device from the Bluetooth list in the phone's settings, and also remove it from the Mi Fit application itself.
Then reset the bracelet itself. To do this, look up the System menu (or More) on the bracelet screen and select Unbind. Then the bracelet will return to the factory settings. Now re-search the device in the app and pair.
This method helps in 90% of cases when time does not want to sync, it clears all temporary files and encryption key conflicts between the phone and the tracker, and once you reset the bracelet will work as new.
💡
Unbind and re-pairing are the most effective solution for eliminating (stubborn) time-data synchronization errors.
It’s also worth checking whether the phone’s power-saving system is blocking the Mi Fit app. On many smartphones (especially Xiaomi, Huawei, Samsung), aggressive battery settings can “kill” the application’s background process, which causes time synchronization to fail on time.
