Modern wearable gadgets from Xiaomi have become an integral part of the smart home ecosystem, but their correct operation depends on the accuracy of system time. If your device is confused time or date, this can lead to incorrect display of notifications, errors in tracking training and problems with synchronization of health data. Owners often face a situation when after draining the battery or reconnecting to the smartphone dial shows incorrect values.
Fortunately, the timing process is largely automated and requires no technical expertise. Most models, including the popular Amazfit series, the Mi BandMi Watch, rely on synchronization with the phone. However, there are nuances that can disrupt this process, requiring manual user intervention to restore functionality.
In this article, we will take a look at all the possible ways to set the right time, from standard sync through the app to forced resetting. You will learn why a gadget can ignore smartphone commands and how to fix things if standard methods don’t work. Time accuracy is critical for alarm clocks and reminders, so you shouldn’t ignore discrepancies.
Before we move on to radical measures, we need to understand the basic principle of how these devices work. SIM-Time cards from the cellular operator's network (with the rare exception of eSIM models) act as a secondary display, broadcasting data from a conjugated smartphone.
Time synchronization principles in Xiaomi ecosystem
The fundamental basis for correct time is a stable Bluetooth connection. Once a wearable device connects to the phone, it requests up-to-date data about hours, minutes, seconds, and the current date and day of the week, a process that takes place in the background and usually takes a fraction of a second.
However, if the connection is unstable or the companion app is not working properly, synchronization may not occur. It is important to understand that time zone settings are also taken from the Android or iOS system. If the phone is exposed to the wrong region, the watch will automatically copy this error. Automatic synchronization is the main mechanism that must work without the user.
⚠️ Note: If you travel frequently and change time zones, make sure that your smartphone has an automatic geolocation option for correct time change.
In some cases, especially when using third-party dials or custom firmware, the update mechanism may fail, and the display time continues to go, but lags or rushes relative to the real one, in which case a forced update of data through the application menu is required.
Setup via Mi Fitness and Zepp Life
Two main applications are used to manage most Xiaomi devices: Zepp Life (formerly Mi Fit) and Mi Fitness (formerly Xiaomi Wear), which depends on the specific model of your gadget, and it is through these programs that the initial setting and subsequent correction of time parameters are made.
The sync process in Mi Fitness occurs every time you open the Device tab. Just launch the app, wait for the green connection icon to appear, and check the wrist time. If discrepancies persist, try the following steps:
- 🔄 Open the application and go to the Profile tab, then select your device and click the Sync button".
- 📱 Check if Bluetooth is on on your smartphone and if the app has permission to work in the background.
- 🌐 Make sure that the phone in the date and time settings is ticked "Use network time".
The logic of Zepp Life is similar: time is updated when you log in to the device menu. If the automatic update doesn't work, you can try turning off Bluetooth on your phone, wait 10 seconds and turn it on again, then reconnect with the clock, and the stability of the connection is crucial here.
☑️ Checking the synchronization settings
It’s worth noting that some older models may require re-pairing to reset sync errors, in which case you need to remove the device from the Bluetooth list in your phone’s settings and re-search and connect through the app.
Manual setting of time on the device
While most Xiaomi models don’t have a full-fledged interface for manual time input (hours and minutes), some advanced versions, such as the Mi Watch or Redmi Watch, allow you to change the time zone or time format directly on the screen of the gadget.
To access the settings on the device itself, you usually need to:
- ⌚ Swipe down or press the side button to call the menu.
- ⚙️ Find the "Settings" section (cog icon).
- 🕒 Select "System" or "Date and time".
If your model supports manual input, you can change your time zone, which automatically adjusts the time. The simpler Mi Band fitness bracelets don't have that option, they're completely smartphone dependent, and the only solution is to set up the phone.
⚠️ Warning: Manually changing the clock time without syncing with the phone will lead to desynchronization of data on training and sleep in the application.
Therefore, manual adjustment is temporary and only serves for emergencies.
Change of time and time zone format
Many users prefer the 24-hour format over the 12-hour format (AM/PM), which is also changed through a companion app or smartphone settings. In some versions of MIUI or HyperOS firmware, format settings can be duplicated.
To change the format, follow the following steps:
Phone settings → Additional settings → Date and time → Time format (24 hours)When you change the setting on your phone, you need to update the data on your watch. If the format hasn't changed, try temporarily disabling Bluetooth, changing the setting on your phone, turning on Bluetooth, and reconnecting the device. The display format is often cached in the gadget's memory.
Time zones are more complicated. If you move to another city, the clock must automatically adjust if the phone is geolocated, but if you use a VPN or static IP settings, the phone can "think" it's in another country, in which case the time difference will persist until the network settings are fixed.
| Parameter | Where to set up | Impact on work |
|---|---|---|
| Time zone | Smartphone (automatically) | The right time when traveling |
| Format (12/24) | Smartphone/Application | Convenience of reading time |
| Date. | Synchronization | Correct statistics for days |
| First day of the week | Smartphone (region) | Displaying weekly statistics |
Resolving problems with desynchronization
When the clock is running away or lagging, it can indicate a software failure, and most often the problem is not the device itself, but the conflict of versions of the software or the overflowing memory of the Bluetooth stack on the phone. The first step should always be to reboot both devices.
If a simple reboot didn’t help, try a more radical method – breaking the link and re-pairing:
- 🗑️ Remove the device from the list of paired in the Bluetooth phone settings.
- 📲 Remove the device from the list in the Mi Fitness or Zepp Life app.
- 🔄 Reset the clock settings to factory (via the menu on the clock).
- 🔗 Re-interconnect the process as with a new device.
This method helps in 90% of cases, as it clears the synchronization cache and eliminates erroneous entries in the memory of the gadget, resetting also removes accumulated system errors that may have affected the timer.
⚠️ Before performing a full reset, make sure that all important training data is synchronized with the server, otherwise it will be lost.
It's also worth checking for firmware updates for your watch. Manufacturers regularly release patches that fix time and date errors. You can find the update in the device profile in the app.
Features of work in flight mode and without a phone
Xiaomi’s smartwatches continue to go even without communication with your phone, using an internal quartz generator. The accuracy of this generator is high, but over time, there can be an error of a few seconds a day. If you wear a watch for long periods in flight mode or without a phone, the discrepancy can become noticeable.
In Airplane Mode on the watch itself (if the model supports it), Bluetooth shuts down and synchronization becomes impossible. Time keeps going based on the last known value. Once you turn off flight mode and connect to the phone, the time instantly updates.
It is important to consider that when the battery is completely discharged and then charged without connecting to the phone, the time can be reset to a default value (for example, 00:00 or the release date of the firmware), in this case, connecting to the smartphone is necessary to initialize the correct data.
