How to change time on Xiaomi Mi Band 7: synchronization and manual setting

The Xiaomi Mi Band 7 fitness bracelet automatically syncs time with a connected smartphone via the Mi Fitness app (or Zepp Life for new versions). However, sometimes users face problems: the clock on the bracelet screen is behind, in a hurry or even shows the wrong date. The reasons can be different from a Bluetooth connection failure to firmware errors. In this article, we will discuss all the working ways to change the time on the Mi Band 7, including forced synchronization, manual adjustment through hidden settings and solving typical errors.

It's important to understand that the Mi Band 7 doesn't have its own interface for direct time change -- all settings go through the smartphone. But if automatic synchronization doesn't work, there are workarounds. We tested them on firmware 1.20.5.14 and 1.22.0.19 (current for 2026), so the instructions will work even on the latest updates. For convenience, the sections of the article are structured from simple solutions to more complex ones so you can quickly find the right method.

Why Mi Band 7 is the wrong time: 5 main reasons

Before you start setting up, you should figure out why the bracelet is showing the wrong time. 80 percent of the time, the problem is not with the device itself, but with the smartphone or the app settings. Here are the key reasons:

• 📱 Bluetooth or unstable connection is disabled (bracelet loses communication with smartphone).
• ⏰ Incorrect time settings on a smartphone – if the phone is manual date / time, and not automatic synchronization over the network.
• 🔄 Older version of the app (Mi Fitness or Zepp Life) – bugs in older versions can block synchronization.
• 📲 Failure of the firmware bracelet – especially after a failed update or reset settings.
• 🌍 Wrong time zone in phone settings (for example, when traveling to another country).

If the bracelet shows a time several hours apart, check first the phone Settings → Date and time. Android should have Automatic Date and Time enabled, and iPhone should have Automatic Set option in Main → Date and Time. Mi Band 7 does not have its own time database - it is completely dependent on the data of the smartphone.

⚠️ Warning: If the bracelet displays a date of December 31, 2000 or January 1, 1970, this is a sign of a critical firmware failure, in which case a complete reset of the device will be required (instructions in the section below).

Method 1: Forced time synchronization with Mi Fitness/Zepp Life

The simplest method is to get the app to re-send the time data to the bracelet.

1. Open the Mi Fitness app (or Zepp Life for newer versions).
2. Make sure the bracelet is connected to the phone (the Bluetooth icon should be on the top of the screen).
3. Go to the Profile section → Mi Smart Band 7.
4. Pull the screen down to update the data (swipe down gesture).
5. If the time is not updated, press three dots (⋮) in the upper right corner and select "Sync the data».

After that, the bracelet should "catch" the current time. If the synchronization did not pass, try:

• 🔄 Reset the bracelet (press the touch button 10 seconds before vibration).
• 📱 Restart Bluetooth on your smartphone (disable / turn on in the settings).
• 🔌 Remove and re-insert the bracelet into the charger (sometimes this resets the connection).

Check if Bluetooth is on on your phone

Update the Mi Fitness/Zepp Life app to the latest version

Make sure that the phone has an automatic time.

Reset the bracelet (hold the button for 10 seconds)-->

If forced synchronization doesn’t help, move on to the next method – manually configure through a hidden menu.

Method 2: Manual time change through engineering menu (for advanced)

The Mi Band 7 has a hidden engineering menu that you can manually adjust the time, and it doesn't work on all firmware, but it's worth a try.

1. On the bracelet, go to the main screen (swipe up from the dial).
2. Touch the touch button 5 times in a row (with an interval of ~1 second).
3. After the fifth touch, a menu will appear with the inscription TEST.
4. Scroll down to Time Sync (or Set Time in some versions).
5. Press it and confirm the action (the bracelet vibrates).

After that, the bracelet will request data from the smartphone and update the time. If the “Time Sync” item is not on the menu, then your firmware does not support this function - try updating the bracelet (section below).

⚠️ Note: Do not change other options in the engineering menu (TEST) Incorrect settings can cause sensors to fail or vibration to shut down.

Method 3: Update the bracelet firmware to correct time errors

If the time on the Mi Band 7 is regularly lost, the problem may be with outdated firmware. Xiaomi periodically releases updates to fix synchronization bugs.

1. Open Mi Fitness or Zepp Life.
2. Go to Profile → Mi Smart Band 7 → Update firmware.
3. If a new version is available, click “Update” and wait until it is completed (the bracelet will reboot).

Important nuances:

• 🔋 The bracelet should be over 50% charged, otherwise the update will be interrupted.
• 📶 Connect your phone to Wi-Fi – Update via mobile internet may freeze.
• ⏳ If the bracelet is “hanging” during the upgrade phase, wait 10-15 minutes.

If after the update time is still lost, try to reset the bracelet to factory settings (instructions in the next section).

1.20.5.14 or older |1.22.0.19|1.25.1.8 (up-to-date) | I don't know my version-->

Method 4: Resetting the bracelet to factory settings

The last resort, if other methods fail, is to completely reset the Mi Band 7, which will remove all the data from the bracelet (steps, alarm settings, training profiles), but often solves time problems.

1. On the bracelet, go to Settings → System → Reset (or Settings → More → Reset in English).
2. Confirm the action by clicking the tick (✓).
3. After the reboot, connect the bracelet to your phone again via Mi Fitness.

After reset, the time should be synchronized automatically. If the problem persists, check:

• 📲 Application permissions – Mi Fitness must have Bluetooth access, Location and Date/Time.
• 🔄 Conflict with other apps – Google Fit or Apple Health, for example – can block syncing.

⚠️ Note: After resetting, the bracelet may request a re-assignment to your Xiaomi account. Use the same account as before, otherwise your training statistics will be lost.

Solving specific time problems on the Mi Band 7

Sometimes the time on the wristband is unusual, and let's look at the typical scenarios and their solutions.

1.The time on the bracelet is in a hurry or is behind by a few minutes

This is due to a hardware failure of the quartz generator (rarely encountered, usually on bracelets with physical injuries).

• 🔧 Calibrate the time through the engineering menu (Time Calibration section, if available).
• 📦 Contact the service center – if the warranty is valid, the bracelet will be replaced.

2.After replacing the battery, time is lost

When replacing the battery (for example, after 2-3 years of use), the settings are often confused.

• 🔋 Fully charge the bracelet (up to 100%).
• 🔄 Perform reset and re-synchronization.

3.Time changes by itself (e.g. at night)

The culprit is background synchronization with Xiaomi servers.

1. In Mi Fitness, go to Profile → Mi Smart Band 7 → Notifications.
2. Turn off the "Autosynchronization" option.
3. Manually update the time as needed (Section 1 of this article).

💡

If the bracelet often loses touch with your smartphone, add Mi Fitness to the battery optimization exceptions (on Android: Settings → Applications → Mi Fitness → Battery → No restrictions).

Frequent errors in setting time and how to avoid them

Many users make the same mistakes when trying to change the time to the Mi Band 7.

• ❌ Turning off Bluetooth during synchronization will interrupt data transfer, and time will reset to factory settings.
• ❌ Set time manually on your smartphone if the bracelet is connected. Always use automatic network synchronization.
• ❌ Use third-party applications to change time (e.g. Notify & Fitness or Tools & Mi Band) and they often conflict with official software.
• ❌ Reset the bracelet without linking to the account – this can block access to features (for example, to pay Mi Pay).

If you encounter a Mi Fitness “Data Synced” error, try:

1. Remove the bracelet from the application and connect it again.
2. Clear the Mi Fitness cache (Phone Settings → Applications → Mi Fitness → Memory → Clear the cache).
3. Reinstall the app.

💡

If the bracelet is not synced with the iPhone, check if the settings of the phone are enabled settings → Bluetooth → Share system time (for iOS 16+).
