Owning modern wearables means constantly synchronizing with the digital rhythm of life, and the first step after unpacking is always to adjust the timing. Many users are faced with a situation where newly purchased smartwatches show the wrong time or date, which can cause confusion in the planning of the day. Fortunately, the architecture of the operating systems used in Xiaomi devices is built on the principle of automatic synchronization, which reduces the need for manual adjustment to a minimum.
However, sometimes automatic mechanisms fail due to software errors, Bluetooth connection problems, or the operating system of a smartphone. In such cases, the owner of the device needs to understand how the process of transferring time tags from phone to accessory works. Xiaomi smart watches and their sub-brands, such as Amazfit, do not have their own built-in battery to store time settings at full discharge, so they are completely dependent on the signal source.
In this article, we will take a look at all aspects of time zone configuration, watch format, and common desynchronization issues, and explain why a gadget can persistently show another city’s time and how to force an app to update data. Understanding these processes will help avoid unnecessary trips to the service center and quickly return the device to working condition.
Time synchronization principles in Xiaomi ecosystem
The key to any Xiaomi wearable is that it integrates closely with a smartphone. Time synchronization is not done through the internet connection of the watch itself (although some models with eSIM do), but primarily through the Bluetooth link to the phone. When you connect a tracker or watch to a companion app like Mi Fitness, Zepp Life or Zepp, the initial data exchange involves the transfer of the current date and time.
It’s important to understand that Xiaomi gadgets themselves often don’t have an interface for manually entering hours and minutes in device settings.All the logic resides on the mobile app side. If your smartphone is set to the right time but the clock shows a different one, it means that the data channel is broken or the application does not have the necessary permissions for background work.
There are several levels of time checks: first, the phone's operating system is checked with a network operator or an Internet server, then that data is transmitted to a wearable app, and then the final step is to broadcast the signal to a fitness bracelet or watch, and the gap in any of these steps leads to the display of incorrect information on the accessory display.
💡
Xiaomi smartwatches do not have their own time saving system at full discharge and depend on synchronization with the smartphone at each connection.
⚠️ Note: If you have changed your time zone after moving to another city, don't try to change the time manually on your watch. This is not possible. You need to change the time settings on your smartphone or wait for the automatic network switch, after which the clock will automatically update.
Necessary applications for device management
The right software is critical to successfully set up and manage your device. Xiaomi's ecosystem is divided into multiple branches, and different applications are designed for different models. For example, the popular Mi Band 4, 5, 6 models have historically used the Mi Fit app, which was later renamed Zepp Life. New models such as the Mi Band 7, 8 and the Watch S series often require the installation of the Mi Fitness app.
Installing an inappropriate app is one of the common reasons why watches can't sync time. If you're trying to connect a device through an app that doesn't support your model, the pairing process will either not complete or pass without passing on the profile settings. Always check. QR-code in the instruction manual or on the device box for downloading the current version of the software.
It is also important to keep an eye on the versions of the apps themselves, as developers regularly release updates to fix connection bugs, and an outdated version of the program may not properly process time zone data, especially if there are changes in security protocols on Android or iOS.
Compatibility of applications and models
Step-by-step instructions: setting up via smartphone
The process of setting the right time does not require complex manipulations if you follow a certain algorithm of actions. The first step should always be to check the settings of the smartphone itself, as it is a master device in this bundle. Make sure that in the Settings → Date and time section, the item “Use network time” or “Automatic date and time” is activated.
Once you check the phone, you need to have a stable connection. Turn off and turn on Bluetooth on your smartphone, then open the watch management app. Wait for the Connected status to appear on the program's home screen, at which point a background data packet is transmitted that includes the current time.
☑️ Checklist of synchronization
If automatic synchronization does not occur, you can try to force the data to update, for this purpose, in some versions of applications there is a button to update the device profile, and also an effective method is to temporarily disconnect the clock from the account and re-pair, which forces the system to re-enter the entire cycle of the initial configuration.
Manual setting of time zone and time format
While direct time change on the watch screen is not usually available, users can often influence the format of its display and the choice of time zone through the app. In the device profile settings under Device Settings → Time settings (the path may differ depending on the model), you can find options for switching between the 12-hour and 24-hour formats.
Special attention should be paid to the situation of travel, if you are roaming or using two. SIM-In Zepp Life or Mi Fitness, you can sometimes find the option of forced region selection, which will be broadcast on the clock, ignoring the geolocation of the phone.
For models with Wear OS (such as the Xiaomi Watch 2 Pro), the options are wider. In such devices, you can go to Settings → System → Date and Time directly on the watch screen and turn off automatic synchronization by setting the time manually. However, for most fitness trackers in the Mi Band series, this path is closed, and the reliance on the smartphone remains absolute.
💡
To quickly switch the time format (12/24 hours) without digging deep into the menu, try changing the dial. Many third-party dials have their own time format settings that are prioritized over the system.
Table of correspondence of applications and synchronization functions
Different device models use different data protocols, which affects the speed and reliability of updating time. Below is a table that helps you determine which application is responsible for synchronizing in your case and what features it supports.
| Model of the device | Main annex | Alternative software | Manual setting on the clock |
|---|---|---|---|
| Mi Band 1-3 | Mi Fit | No | No. |
| Mi Band 4-6 | Zepp Life | Mi Fitness (ric). | No. |
| Mi Band 7-9 | Mi Fitness | Notify for Mi Band | No. |
| Xiaomi Watch S1/S3 | Mi Fitness | No | No (format only) |
| Xiaomi Watch 2 Pro | Mi Fitness | Google Clock | Yes (Wear OS) |
Using third-party apps like Notify for Mi Band, which allows for enhanced control, often allows you to set up a rule that if the clock is more than 1 minute different from the phone, force sync, a useful feature for devices that are prone to periodic time escape.
Problem Solving: The clock is lagging or showing the wrong time
The most common problem is when the clock shows a time that differs by exactly one hour or several hours, which almost always indicates an error in determining the time zone.
Another common reason is aggressive energy savings. Android operating systems often kill application background processes to save battery power. If a Zepp Life or Mi Fitness app doesn't have permission to work in the background, it won't be able to transmit a refresh signal when the phone's screen is off. You need to add an app to battery exclusions.
⚠️ Warning: If after fully draining the watch battery (up to 0%) and then charging, the time is reset to 00:00 or the year to 2000, this is normal behavior. Just plug the watch into the phone and time will recover. Don't panic, it's not a breakdown.
If nothing works, try resetting your device completely. In the app, find Profile → Select device → Break a pair or Reset. Then pair again. In 95% of cases, this solves the desynchronization problem.
