Xiaomi’s smart wearables have long been the standard in their segment, offering users a great balance between functionality and price. However, even proven gadgets sometimes have failures in basic features such as displaying correct times. Wrong time zone or synchronization failure can turn a useful device into a source of confusion, especially if you are used to relying on notifications and alarm clocks.
In most cases, the problem is solved quickly if you understand the logic of the smartphone-watch bundle. Automatic synchronization is a priority method, but it requires the correct initial setup in the companion application. If you just unpacked the device or updated the firmware, ignoring the basic steps can lead to the gadget showing a time different from the real one, which is especially critical when using workout timers.
In this article, we will take a look at all possible scenarios, from standard settings through the app to manual interventions in system settings. You will learn why Xiaomi Wear or Mi Fitness can conflict with the phone’s system time and how to force data updates.
Time synchronization principles in Xiaomi ecosystem
It is fundamental to understand that Xiaomi smartwatches, whether it is the budget model Amazfit Bip or the flagship Xiaomi Watch S1, rarely have their own atomic clock inside. The main source of accurate time is your smartphone. When connected via Bluetooth, devices exchange data packets, where one of the first transmitted is the current time stamp.
The data exchange is in the background, but the initial installation or after the connection break requires active user participation. If the phone is set the right time, but on the clock it is different, then the synchronization protocol was broken, this can occur due to aggressive energy savings operating system Android or iOS, which "sleeps" the background processes of the application.
💡
Turn on geolocation on your smartphone when you first pair it – it helps the watch automatically determine the correct time zone, even if you are roaming.
It is worth noting that some models support independent work with Wi-Fi or eSIM networks. In such cases, Xiaomi watches can receive time data directly from the network, bypassing the phone. However, even in this case, priority is given to the settings obtained from the last successful connection to the smartphone, which creates a hierarchy of time sources.
- 📱 The main source of time is the system clock of the conjugated smartphone.
- 🔄 Synchronization occurs automatically when the phone screen is unlocked.
- 🌐 Wi-Fi models can update time over the Internet on their own.
- ⚙️ Mi Fit, Zepp Life and Xiaomi Wear Apps Use Different Synchronization Algorithms.
Setup via Mi Fitness and Zepp Life
Most Xiaomi wearables are controlled by Mi Fitness (formerly Xiaomi Wear) or Zepp Life (formerly Mi Fit) apps that depend on the specific model of your gadget, and that’s where the master switch is often overlooked when looking for the cause of the wrong time.
Once you log in to your device profile, you need to go to the settings section. The interface may be different, but the logic remains the same: look for a item related to system settings or a profile. There's often a "Sync Device Time" option that needs to be activated. Without this tick, the watch will live on its internal timer, which will inevitably start to lag.
☑️ Checking the synchronization settings
In the Zepp Life app, the path is usually: Profile → Select Device → Settings → Time Synchronization. In Mi Fitness, the structure is similar to: Device → Device Settings → System Settings. If the slider is active but the time is not updated, try switching it to Off, wait 10 seconds and turn it on again. This action initiates a forced request for time data from the phone.
⚠️ Note: If after switching on synchronization time on the clock still does not change, check whether the smartphone is not enabled mode "Autosetting time" in the system settings Android/iOS. The watch takes data from there, and if the phone shows the wrong time, the watch will copy the error.
Manual adjustment and time zone management
Situations where automatic adjustment is impossible or undesirable are less common, but they do exist, such as you are in an area with unstable network coverage, or your phone shows the time of another region due to the nature of virtualization. SIM-In such cases, manual intervention may be required.
It’s worth remembering that most modern Xiaomi watches don’t allow you to manually set the time directly on the screen of the gadget through the settings menu, this is done specifically to avoid desynchronization with notifications. The only way to manually adjust is to change the time at the source (smartphone) and then synchronize.
However, if you're traveling, it's critical to set your time zone right. The clock can automatically turn hands when you change geolocation, but sometimes the mechanism fails. You can find a time zone setting in the companion app. Make sure it's "Automatic" or manually indicates your current region.
| Model clock | Annex | Ability to manually adjust | Synchronization by GPS |
|---|---|---|---|
| Amazfit Bip / Lite | Zepp Life | No (only via phone) | No. |
| Redmi Watch | Mi Fitness | No. | No. |
| Xiaomi Watch S1 / S1 Pro | Mi Fitness | No. | Yeah (in activity) |
| Xiaomi Smart Band 8 | Mi Fitness | No. | No. |
If you use a watch while traveling, the time zone change on your phone should happen automatically when you connect to the local network, which will instantly update the data on the watch. If this does not happen, check the date and time settings on Android or iOS itself, making sure that the “Use Network Time” check box is ticked.
Solving problems with desynchronization and resetting
There are times when all the settings are correct, but the time on the Xiaomi Smart Band display or watch still floats. This is a classic symptom of a software failure in the Bluetooth module or in the application itself. The first step should always be to reboot both devices. Turn off the clock through the menu and restart the smartphone.
If the reboot didn't work, try "forgetting" the device in your phone's Bluetooth settings, then removing it from the device list in the Mi Fitness or Zepp Life app. After that, pair it again.This process clears the connection cache and often eliminates data transfer errors, including time stamps.
What to do if the time is reset by 00
It's also worth checking the permissions for the companion app. In the phone's settings, look for the Mi Fitness or Zepp Life app and make sure it's allowed to run in the background and have access to the location. Without those permissions, the system can block the synchronization process, considering it an unnecessary waste of resources.
- 🔋 Fully discharge and charge the clock to 100% to calibrate the controller.
- 🗑️ Remove and reinstall the companion app.
- 🔗 Untie the device in Bluetooth and perform re-pairing.
- 📲 Check for firmware updates for the watch in the app.
Impact of firmware and system updates on timekeeping
Manufacturers regularly release firmware updates for their devices, and often on the changelog list you can find the item “Improving connection stability” or “Time synchronization errors fixed.” An outdated version of the software may contain bugs that interfere with the correct operation of the watch.
Check for updates directly in the app. Go to the device profile and click on the firmware version or the "Check Updates" button. If a new version is available, it is recommended to install it, pre-charge the clock at least 50-60%. The update process can take several minutes, and at this time the screen can go out - this is normal.
⚠️ Warning: Never interrupt the firmware update process, even if the clock seems to be hanging. Interrupting system file writing can cause the device to stop turning on (called a “brick”), and it will be extremely difficult to restore it without special equipment.
Sometimes, after updating the firmware, the time settings can get lost, which is a well-known feature of some versions of the software, when user preferences are reset, in which case it is enough to re-sync through the application, if the problem repeats after each update, it makes sense to wait for the next patch or temporarily roll back to the previous version, if this is possible for the manufacturer.
Specifics of settings for different series of devices
Xiaomi’s line of wearable electronics is extensive, and the nuances of customization may vary. For example, the Amazfit series (which is made for Xiaomi) tightly integrated with the Huami ecosystem and requires a Zepp Life or Zepp app. At the same time, new Xiaomi-branded models such as the Watch S1 or the Mi Smart Band 6/7/8 bracelets often use the Mi Fitness platform.
For children's watches Xiaomi, such as Mi Bunny or 70mai Kids Watch, the time adjustment process is done exclusively through the server, and the watch receives the exact time from the cellular network it's inserted into. SIM-If the clock is wrong, the problem is almost always the operator settings or incorrect activation. SIM-maps in the Mi Bunny app.
💡
Different watches require different applications to control: old models are Mi Fit/Zepp Life, new ones are Mi Fitness, children's models are Mi Bunny. Make sure you use the right software.
Special attention should be paid to devices with the Wear OS operating system (for example, Xiaomi Watch 2 Pro), where the time setting is done by standard Google tools, and synchronization with the Android phone is at the system level, not just the application level, and it is important that the phone has installed Google Play services and they work correctly.
