How to set the time on Xiaomi Mi Band 4: automatic and manual synchronization

The Xiaomi Mi Band 4 fitness bracelet automatically synchronizes time with a connected smartphone, but sometimes users face problems: the clock is lagging, rushing or showing the wrong time zone. The reasons can vary from a Bluetooth communication failure to incorrect settings in the Mi Fit app (or its alternatives like Zepp Life). In this article, we will discuss all the ways to adjust time, including forced synchronization, manual adjustment and solving typical errors.

The Mi Band 4 has no GPS module or mobile network connection, which is only updated via a smartphone, which means that if the phone is not properly timed or Bluetooth is disabled, the bracelet will also show incorrect data, and we will take a detailed look at how to avoid such situations and what to do if automatic synchronization does not work.

Why is Mi Band 4 the wrong time?

Before you set up a watch, it is important to understand the cause of the failure.

• 📱 Unsynchronized time on a smartphone: If the phone has the wrong time zone or date, the bracelet takes that data.
• 🔄 Bluetooth communication failure: temporarily shutting down the module or going beyond range (more than 10 meters) leads to “hang” time.
• 🔧 Mi Fit errors: outdated version of the program, cache or incorrect profile settings.
• 🔋 Battery discharge: At a charge level below 10%, the bracelet may not process data correctly.

In 90% of cases, the problem is solved by simply resynchronizing through the application, but if time is lost regularly, it is worth checking the time zone settings on your smartphone and updating the firmware of the bracelet.

Method 1: Automatic synchronization via Mi Fit

This is the basic method that works in most cases. The algorithm is simple:

1. Open the Mi Fit app on your smartphone and make sure the bracelet is connected (the Bluetooth icon is active).

If there is no sync button, try:

• 🔄 Reset the bracelet (press the touch button 10 seconds before vibration).
• 📱 Restart the Mi Fit app and reconnect the device.
• 🔧 Update the bracelet firmware through Settings → Update of the PO.

Important: After syncing, check if the time on the bracelet and smartphone matches. If the difference persists, go to manual settings.

Method 2: Manually adjusting time through the bracelet menu

If automatic synchronization doesn’t work, you can try changing time zones directly on the wristband, a method that is suitable for users with third-party firmware (such as Amazfit or custom), where advanced settings are available.

Instructions:

1. On the bracelet, scroll down to the Other (or Settings) point.
2. Select the time and date (in some firmware - time zones).
3. Set the correct time zone (e.g. GMT+3 for Moscow).
4. Save the changes and wait for the bracelet to reboot.

After manually adjusting, time may be lost the next time you connect to your phone, the bracelet syncs again with your smartphone data. To avoid this, turn off automatic sync in Mi Fit:

1. Open Profile. → Mi Smart Band 4 → Additionally.
2. Find the auto-synchronize time option and deactivate it.

💡

If after manual settings time still gets lost, try calibrating the bracelet: go to Settings → System → Calibration of time (not available in all firmware).

Method 3: Resetting the bracelet to factory settings

If none of the methods worked, it may require a complete reset of the device, which will delete all the data (steps, pulse, alarm clocks), but often solves synchronization problems.

How to Reset Mi Band 4:

1. On the bracelet, go to More → Settings → Reset.
2. Confirm the action by clicking the tick (the bracelet vibrates and reboots).
3. Once enabled, reconnect it to Mi Fit as a new device.

Alternative method (if menu is not available):

• 🔋 Discharge the bracelet until completely disconnected.
• 🔌 Charge it to 100% and hold the touch button for 15 seconds – it will force reset the settings.

💡

Reset removes all data from the bracelet, including activity history. Before the procedure, export the statistics to Mi Fit (Section Profile → Export data).

Solving time zone problems

One of the common reasons for wrong time is the wrong time zone on the smartphone. Mi Band 4 copies these settings, so if the phone is set, for example, GMT+0 (London), the bracelet will also be 3 hours behind for Moscow.

How to check and correct:

1. On Android: Settings → System → Date and time → Time zone. Make sure you select the right region (e.g. Moscow, GMT+3). Turn off the option Automatically if it knocks down the belt.
2. On iPhone: Settings → Basic → Date and time → Time zone. Enable Automatic Set or select city manually.

If you travel frequently, it is recommended to enable the option on your smartphone Automatic time zone, which will allow the bracelet to automatically adjust to the new region.

Update the firmware to correct time errors

Some versions of the Mi Band 4 firmware have bugs that cause sync failures, such as firmware 1.0.9.14, where the bracelet "forgot" time after disconnecting from the phone, and the solution is to upgrade to the latest version.

How to update firmware:

1. Open Mi Fit and go to Profile → Mi Smart Band 4.
2. Click on the three dots in the top right corner and select Software Update.
3. If a new version is available, confirm installation. The bracelet will reset.

If the update does not appear:

• 📱 Check out the Mi Fit app version on Google Play or App Store – update it.
• 🔌 Make sure the bracelet is at least 50 times charged%.
• 🌐 Connect to stable Wi-Fi – some upgrades require internet access.

💡

If the update is stuck in Prepare, restart Mi Fit and try again. If the problem persists, uninstall and reinstall the application.

What do you do if nothing helps?

If all of the above methods have failed, there may be a problem with the hardware of the bracelet.

• 🔧 Checking charging contacts: sometimes oxidation of contacts leads to malfunctions.
• 📦 Replacement of the strap: In rare cases, a faulty strap can affect the stability of the job (especially if it is damaged).
• 🔋 Full discharge and charging: discharge the bracelet to 0%, then charge to 100% without interruptions.
• 📡 Changing your smartphone to connect: Try connecting the bracelet to another phone to rule out Bluetooth module problems.

⚠️ Note: if the bracelet stopped synchronizing the time after falling or getting moisture, this may indicate damage to the internal components.In this case, contact the Xiaomi service center - self-repair can lead to complete breakdown.

If the warranty is still valid (usually 12 months), contact Xiaomi support via the official website or contact the store where you bought the bracelet.

• Check or electronic confirmation of purchase.
• Box and components (charge cable).
• Serial number of the device (located on the back of the module).
