Xiaomi Mi Band 4 automatically syncs time with your smartphone via the Mi Fit or Zepp Life app (formerly Mi Fit in some regions). But what if the watch on the wristband shows the wrong time, lags or doesn't update at all? In this article, we will discuss all the working ways of changing time, from basic synchronization to manual settings and solving typical errors.
Time issues on the Mi Band 4 often arise after resetting, updating the firmware or changing the time zone on the phone. Sometimes the bracelet itself is to blame, but in 80% of cases the root of the problem lies in the settings of the smartphone or app, we will explain in detail how to check each of these points and return accurate time readings without contacting the service.
Why Mi Band 4 is the wrong time: the main reasons
Before you change the time, it's important to understand why the bracelet shows it wrong.-5 The reasons that occur most often:
- 📱 No synchronization with the smartphone – the bracelet is not connected to the phone via Bluetooth or the Mi app Fit/Zepp Life is running in the background with limitations.
- ⏰ Wrong time zone on the phone – if the smartphone has the wrong region, the bracelet will show the time with displacement.
- 🔄 Failure after firmware updates – sometimes new versions of the software reset the time settings, especially if the update is interrupted.
- 🔋 Battery discharge – at a charge level below 10%, the bracelet may not process data correctly, including time.
- 📲 Conflict with other fitness apps – if the phone has Google Fit, Apple Health or similar devices installed, they can block sync.
Most of the time, the problem is solved by simple resynchronization, but sometimes you need a deeper setup, and then we'll go through all the methods, from the simplest to the most complex.
Method 1: Automatic time synchronization with Mi Fit/Zepp Life
The most reliable way to update your time on Mi Band 4 is to sync it to your phone through the official app.
- Open the Mi Fit or Zepp Life app on your smartphone.
- Make sure the bracelet is connected to your phone via Bluetooth (the connection icon should be green in the top corner of the screen).
- Go to the main profile page of the bracelet (stamp on its image).
- Pull the screen down to update the data – this will trigger synchronization.
- If time has not changed, go to Profile → Device Settings → Additional → Sync time.
Usually, after these actions, the bracelet shows the current time for 10 to 30 seconds. If the synchronization is not correct, check:
- 📶 Bluetooth status – turn it on and off on your phone.
- 🔄 Background operation of the application - in the phone settings, allow Mi Fit to work in the background (Settings) → Annexes → Mi Fit → Battery → No restrictions).
- 📱 Application permissions – make sure Mi Fit has access to location and calendar (needed to determine time zone).
☑️ Checking before synchronization
If you've recently flown to a different time zone, the bracelet may not automatically update the time, in which case you'll have to do it manually (see next method).
Method 2: Manually changing time through bracelet settings
If automatic synchronization doesn’t work, you can try to force the clock to change through the menu of the bracelet itself, which works even without a phone connection (but requires a time zone setup).
Instructions:
- On the Mi Band 4 bracelet, swipe your finger up the screen to open the menu.
- Find the icon. ⚙️ Settings (cogs) and tap it.
- Scroll down to Time and Date (or Clock in some firmware).
- Select Set a Time and Confirm the Action.
- The bracelet synchronizes the time with the phone or suggests you enter it manually (if there is no connection).
If the time and date item is not on the menu, then your firmware does not support manual settings, in which case only resetting the bracelet (see section below) will help.
What if the menu does not have a time and date item?
Attention! After manually changing the time without synchronizing with your smartphone, the bracelet can knock off readings the next time you connect to your phone, a method recommended only for temporary correction.
Method 3: Resetting the bracelet to factory settings
If neither synchronization nor manual tuning helps, you will have to reset the Mi Band 4 completely, which will return the bracelet to its original parameters, including the correct time, and all data (steps, pulse, settings) will be deleted!
How to reset:
- On the bracelet, go to Settings → Additional → Reset.
- Confirm the action by clicking the tick (or hold the bracelet button for 10 seconds if the sensor does not respond).
- After restarting, connect the bracelet to the phone again via Mi Fit.
- When you first connect, the app automatically synchronizes the time.
If the bracelet does not respond to touch, try a hardware reset:
- 🔌 Turn off the bracelet from charging.
- 📱 Remove it from the list of Bluetooth devices on your phone.
- 🔄 Hold the touch button of the bracelet for 15-20 seconds until the Mi logo appears.
- 🔋 Connect the bracelet to charging for 5 minutes, then repeat the synchronization.
💡
If after resetting the bracelet does not connect to the phone, try to restart the smartphone and install the latest version of the Mi Fit from the official store (App). Store/Google Play).
Problem Solving: Why Time is Stuck or Not Updated
If the time on Mi Band 4 is strayed regularly, the problem may be deeper than it seems.
| Problem. | Possible cause | Decision |
|---|---|---|
| Time is 1-2 hours behind | Wrong time zone on the phone | Check your smartphone time settings (Settings → System → Date and Time). Turn off automatic determination, select your belt manually. |
| Time is lost after disconnecting from the phone | Weak bracelet battery | Charge the bracelet to 100% and calibrate the battery (discharge to 0%, then charge without interruption). |
| Time is not updated after the flight. | The app did not update the time zone | Manually synchronize time through Profile → Device settings → Synchronize. |
| The bracelet shows the time with a delay (lag 5-10 minutes) | Synchronization delay due to battery savings | In the phone settings, turn off battery optimization for Mi Fit. |
If none of the methods worked, the problem may be a hardware failure (e.g., accelerometer or Bluetooth module damaged).
💡
Before visiting the service, check the bracelet on another phone - this will help to eliminate software errors.
More tips: how to avoid time problems in the future
To ensure that the time on Mi Band 4 is always accurate, follow these guidelines:
- 🔄 Update your firmware regularly — new versions of the software fix synchronization errors. Check for updates in Mi Fit → Profile → Update of the PO.
- 📴 Do not turn off Bluetooth on your phone – the bracelet syncs time only when you are actively connected.
- ⚡ Watch the charge – at the battery level below 15%, there may be failures in the operation of sensors.
- 🌍 Update your time zone manually after flights or region changes.
- 📱 Use only one fitness app – conflicts between Mi Fit, Google Fit and Apple Health can knock down settings.
If you travel frequently, turn on Automatic Time Zone Detection (Settings → System → Date and Time) in your phone settings to avoid manually adjusting your bracelet.
⚠️ Note: Some users are experiencing a problem when the Mi Band 4 shows the time in a 12-hour format instead of a 24-hour format. This can only be fixed by resetting the bracelet or updating the firmware - there is no format change option in the standard settings.
