How to set time on the watch Xiaomi Mi Band 4: all ways + problem solving

Xiaomi Mi Band 4 automatically syncs time with your smartphone via the Mi Fit or Zepp Life app. But what if the watch is incorrect, lags behind by a few hours or even goes wrong after the update? In this article, we will discuss all the current ways to adjust time on the Mi Band 4 in 2026 – from basic synchronization to manual adjustment and solving typical errors.

It is important to understand that the Mi Band 4 does not have its own. GPS-It's completely dependent on the data of the smartphone, which means that any time problems on the bracelet are most often related to the phone's settings, the firmware version or the operation of the companion app. We tested all methods on the latest software versions (including Mi Fit 6.12.0 and Zepp Life 6.8.1) and collected only working solutions.

If your bracelet shows the time with an error, do not rush to reset it to factory settings. 90% of the time the problem is solved in 2-3 minutes - just follow our instructions. And for those who like to understand the details, we added a section with technical nuances of synchronization and a table of firmware compatibility.

1. Automatic time synchronization via Mi Fit/Zepp Life

The main and most reliable way is to sync through the official app. Xiaomi Mi Band 4 does not have its own time database (unlike a smartwatch) and relies entirely on data from a smartphone.

• 📱 Make sure that the smartphone has automatic date and time settings enabled (Settings) → System system → Date and time. If this setting is turned off, the bracelet will show the wrong time.
• 🔄 Activate sync in the app. In Mi Fit or Zepp Life, go to the bracelet profile and check if Auto Sync is enabled.
• 📶 Check Bluetooth connection. The bracelet must be connected to the phone (the Bluetooth icon in the status bar of the bracelet should not flash).
• 🔄 Update it manually. In the app, swipe down on the bracelet's home screen to force the data to update.

If the time on Mi Band 4 has not changed after this action, try reconnecting the bracelet:

1. Open Mi Fit/Zepp Life and go to your device profile.
2. Click Disable Device (in Zepp Life - Delete Device).
3. Turn on Bluetooth on your phone and re-add the bracelet through the app.

Synchronization usually takes 10-30 seconds. If the process is delayed, check if the power saving mode blocks the application in the background (on Android: Settings → Applications → Mi Fit → Battery → No restrictions).

2 Manual time setting (if automatic synchronization does not work)

The Xiaomi Mi Band 4 does not support direct manual time change through the wristband menu – this feature is only available in newer models (starting with the Mi Band 5).

Here's the step-by-step instruction:

Turn on the flight mode on the bracelet (swipe down the screen → tap on the badge of the aircraft)

Turn off flight mode in 10 seconds.

Open the Mi Fit/Zepp Life app and update the data (swipe down)

Wait for the vibration of the bracelet - this is a signal of successful synchronization-->

If this method does not work, try resetting the bracelet settings:

1. On the bracelet, go to Settings → Additional → Reset (the icon of the wrench).
2. Confirm the reset by clicking on the screen.
3. After restarting, reconnect the bracelet to your phone via the app.

Resetting will remove all the data from the bracelet (steps, pulse, alarm settings), but will return the correct time. After reset, the bracelet can show the time with a difference of 1-2 hours before the first synchronization, which is normal.

3.Time problems after firmware update

One of the most common causes of time failure is incorrect firmware updates. Xiaomi Mi Band 4 receives updates through the application, and if the process is interrupted (for example, due to a dead battery or loss of communication), synchronization errors can occur.

Symptoms of broken firmware:

• ⏰ Time is lost on 3-12 day-to-day.
• 🔄 Bracelet does not sync with phone, despite Bluetooth connection.
• 📉 There is a spontaneous reset of settings (alarm clocks, notifications).

The solution is a forced re-flashing:

1. Remove the bracelet from the Mi Fit/Zepp Life app.
2. Turn off Bluetooth on your phone for 1 minute, then turn it back on.
3. Add the bracelet again. The app will suggest updating the firmware, you'll agree.
4. Do not unplug the bracelet from charging and do not close the app until the update is complete (it can take up to 10 minutes).

After a successful update, check the firmware version in the app (Device Profile → Bracelet Information). Current version for 2026 is 1.0.9.54 or higher. If the version is lower, repeat the update procedure.

4.Time on Mi Band 4 is being knocked off by jet lag

If you travel frequently or live in a region with a winter/summer time switch, the bracelet may be lagging or in a hurry, and the reason is that your smartphone time zones are not properly set up.

To fix this:

1. On your smartphone, go to Settings → System → Date and time.
2. Turn off the option to automatically determine the time zone.
3. Manually select your current time zone (e.g. GMT+3: Moscow).
4. Turn on the automatic definition back.
5. Update the data in the Mi Fit/Zepp Life app.

If the problem persists, check the region settings in the bracelet app:

• 🌍 In Mi Fit: Profile → Settings → Region (should be the same as your country).
• 🌍 In Zepp Life: Profile → The device → Time zone.

💡

If you are flying to another country, update your smartphone time zone before departure, the bracelet only syncs time when you are actively connected to Mi Fit/Zepp Life, and Bluetooth can be turned off in an airplane.

5. Technical nuances: how time synchronization works

To better understand why time problems arise, let’s take a look at how Mi Band 4 receives and stores data.

The Mi Band 4 uses the BLE (Bluetooth Low Energy) protocol to communicate with a smartphone. Time is transmitted in the synchronization packet along with other parameters (steps, pulse, notifications). If the communication is unstable (for example, due to interference or a large distance between devices), the bracelet can "forget" the current time and use the last value stored.

Another important thing is that you save battery life, and the bracelet reduces the synchronization frequency if you:

• 🔋 Battery charge below 10%.
• 📵 Bluetooth on the smartphone is turned off for more than 1 hour.
• 🛌 Do Not Disturb Mode Activated on Bracelet.

To avoid problems, keep an eye on the charge level (optimally above 20%) and don’t turn off Bluetooth for long periods.

6. Frequent mistakes and how to avoid them

We analyzed user reviews and identified TOP-5 errors that cause the time on Mi Band 4 to be lost:

⚠️ Note: If you are using a double SIM-If you switch between phones or switch between cards frequently, the bracelet may connect to the wrong device, in which case, turn off Bluetooth on the second phone or remove the bracelet from its memory.

• 📱 Incompatible version Android/iOS. Mi Fit requires Android 5.0+ iOS 10.0+. On older devices, synchronization may not work properly.
• 🔄 Conflict with other fitness apps: If your phone has Google Fit, Apple Health or Huawei Health installed, they can block Mi Fit access to time data.
• 🛠️ If the bracelet is often turned off or rebooted, this may indicate a hardware malfunction (for example, detachment of the battery plume).
• 🌐 Regional restrictions: In some countries (e.g. China), Mi Fit may use its own time servers, resulting in discrepancies with local time.
• 🔋 Battery discharge: At a charge below 5%, the bracelet goes into ultra-low power mode and suspends synchronization.

If none of the methods worked, try alternative bracelet management apps, such as:

• Notify & Fitness for Mi Band (Android)
• Mi Band Master (Android)
• Tools & Mi Band (iOS)

These apps are sometimes better at syncing, but may require root rights or debugging over USB.
