How to install and sync your watch on Xiaomi Mi Band 4

The Xiaomi Mi Band 4 fitness bracelet remains one of the most popular activity-tracking gadgets, despite the release of new models, and its main advantage is its ease of use with a wide range of functions, from sleep monitoring to smartphone notifications. However, many users face a basic problem: the watch on the wristband screen shows the wrong time or does not update at all, this can occur after a reset, battery change or synchronization failure.

In this article, we will look at all the possible ways to set time on the Mi Band 4, from automatic synchronization through the Mi Fit app to manual adjustment, pay special attention to the typical errors that cause the clock to “get lost”, and give a checklist to check the settings. If your bracelet shows the time with a delay of several hours or even standing still, here you will find a solution.

Why Mi Band 4 is the wrong time: the main reasons

Before you start setting up, it's important to understand why a watch on a wristband might not work properly, and 90 percent of the time, it's not hardware that's the problem, it's software failures or settings that are wrong, and here are the key reasons:

• 📱 No sync with the phone. The bracelet gets time from the connected smartphone via Bluetooth. If the connection is interrupted or the Mi Fit application does not update the data, the watch freezes».
• ⚙️ Time zone settings fail. If the smartphone or bracelet specifies the wrong region, time will shift by several hours.
• 🔄 Update firmware. When you install a new version of the software on Mi Band 4, you sometimes reset your time settings.
• 🔋 Battery discharge: At a charge level below 10%, the bracelet can turn off background processes, including time synchronization.
• 📲 Conflict with other apps: Some fitness trackers (e.g. Notify & Fitness) may block Mi Fit from accessing data.

Interestingly, the Mi Band 4 doesn’t have its own GPS or internet connection — it’s completely dependent on a smartphone for precise timing, which means that if the phone has the wrong date/time settings, the bracelet will repeat the error.

⚠️ Warning: If after fully charging and reconnecting to the phone, the watch on the bracelet still does not update, check whether the battery saving mode for the Mi Fit application is turned on on on on the smartphone.

Method 1: Automatic time synchronization via Mi Fit

The easiest and most recommended way is to let the bracelet automatically take time from your smartphone.

1. Make sure your phone is Bluetooth enabled and the Mi Band 4 bracelet is connected to the device.
2. Open the Mi Fit app and wait for your bracelet name to appear at the top of the screen (e.g., “Mi Smart Band 4”).
3. Go to the Profile section → Mi Smart Band 4.
4. Scroll down to the Settings Unit and select Date and Time.
5. Activate the time sync switch (if it is turned off).

After that, the bracelet should automatically update the time for 1-2 minutes.

• 🔄 Reset the bracelet: Press the touch button for 10 seconds until vibration appears.
• 📱 Restart the Mi Fit app on your phone.
• 🔗 Disable and reconnect the bracelet in Bluetooth settings.

If automatic synchronization doesn’t work even after these steps, go to manual settings (method 2).

Method 2: Manually set the time on Mi Band 4

In some cases, automatic synchronization may not be available — for example, if you are in a region without support for Xiaomi servers or use custom firmware on the bracelet.

1. Open Mi Fit and go to the bracelet settings (Profile → Mi Smart Band 4).
2. Select a date and a time. → Manually install.
3. Enter the current hours, minutes and select the format (12/24 hours).
4. Click Save and wait for the vibration of the bracelet - this is a signal of a successful update.

Important: manually setting the time does not guarantee automatic updating. The bracelet will count the seconds on its own, but without synchronizing with the smartphone can gradually "go" forward or backward.

• 🕒 Open Mi Fit once every 1-2 days for forced synchronization.
• 🔋 Monitor the charge level of the bracelet (below 15% the time may be lost).
• 📵 Avoid long-term Bluetooth shutdown (more than 12 hours).

💡

If the bracelet still shows incorrect data after manually setting the time, try resetting it to factory settings. To do this, go to Profile → Mi Smart Band 4 → Disable the device and confirm the reset.

How to check if the time on the bracelet is updated

To make sure that the synchronization works correctly, perform a simple test:

1. Remember the current time on the bracelet (for example, 14:30).
2. Turn off Bluetooth on your phone for 5-10 minutes.
3. Turn on Bluetooth back and wait for the Mi Band 4 connection.
4. Compare the time on the wristband to the real one. If it's updated, synchronization works.

If time hasn't changed:

• 📌 Check if the Mi Fit app is locked in battery saving settings (on Android: Settings) → Annexes → Mi Fit → Battery → No restrictions).
• 📌 Make sure your phone has an automatic date and time option on it.
• 📌 Try connecting the bracelet to another smartphone (such as a friend or relative) to help you identify a problem in your bracelet or phone.

⚠️ Note: Some Mi Band 4 firmware (especially custom ones) may not have manual timing options, in which case the only way out is to return to the official firmware via the Mi Fit or Amazfit app (for Chinese versions of the bracelet).

Additional settings: time format and alarm clocks

In addition to the main time on the Mi Band 4 you can configure:

• ⏰ Display format: 12-clockwork (AM/PM) or 24-The watch changes to Mi Fit. → Profile → Mi Smart Band 4 → Display. → Time format.
• 🔔 Alarm clocks: up to 10 repeating signals, tuned to Mi Fit → Profile → Mi Smart Band 4 → Alarm clocks.
• 🌙 Do Not Disturb: Turns off notifications and vibrations at a given time (good for sleep).

If you use a workout bracelet, check the Autopause setting in the Notifications and Reminders section, and when you activate this option, the bracelet will automatically stop the stopwatch if you stop moving for a long time (for example, during a break between approaches in the hall).

Firmware Update: Why It Matters for the Right Time

Many users ignore the firmware updates for Mi Band 4, considering them minor, but they often solve the problems with time synchronization.

• 🕐 Bugs with automatic time synchronization when changing the time zone.
• 🔋 Mistakes that cause the bracelet to “forget” time when the battery is discharged.
• 📱 Conflicts with the latest versions of Android and iOS.

To update the firmware:

1. Open Mi Fit and go to Profile → Mi Smart Band 4.
2. Scroll down and select the firmware update.
3. If a new version is available, click Update and wait for the process to be completed (the bracelet will reboot).

Important: during the upgrade, do not turn off Bluetooth or the bracelet. The process can take up to 5 minutes. If the update is interrupted, the bracelet may stop turning on, in which case only resetting through the pressing of the button for 20+ seconds will help.

💡

Regular firmware updates to the Mi Band 4 not only fix bugs over time, but also add new features (e.g. support for additional workout types or widgets).
