How to change the time on the Xiaomi Mi Band 4: synchronization and manual adjustment

Why Mi Band 4 is the wrong time and how to fix it

The Xiaomi Mi Band 4 fitness bracelet automatically synchronizes time with a connected smartphone via the Mi Fit or Zepp Life app. However, users often experience a situation where the watch on the bracelet screen begins to lag, rush or show the wrong date. The reasons can be different from banal synchronization errors to firmware failures.

In 80% of cases, the problem is solved by simply resynchronizing with the phone, but sometimes you need to manually adjust the time or even reset the bracelet to factory parameters. In this article, we will discuss all the ways, from the simplest to the most radical, and also explain why the Mi Band 4 can show the time with a difference of several hours, even if on a smartphone everything is correct.

If your bracelet is 2-3 hours behind or shows time from a different time zone, don’t be quick to blame the manufacturer. Most often, automatic transition to winter/summer time, which is not always correctly processed by the application, followed by step-by-step instructions for Android and iOS.

Method 1: Automatic time synchronization with Mi Fit/Zepp Life

By default, the Mi Band 4 receives the time and date data from your smartphone every time you connect via Bluetooth. If the sync is lost, first check:

• 📱 Application Version – Outdated Mi Fit versions (below 4.6.0) may mistransmit temporary data.
• 🔄 Bluetooth status – if communication is interrupted, the bracelet does not update the time.
• ⏰ Time settings on the phone – if the smartphone is manual date, Mi Band 4 will inherit it.

To force the time to update:

1. Open the Mi Fit or Zepp Life app.
2. Go to the profile of the bracelet (stamp its icon on the home screen).
3. Pull the screen down to update the data – this will trigger synchronization.
4. If it does not help, turn off and reconnect the bracelet in the Bluetooth settings of the smartphone.

💡

If the Mi Band 4 is delayed after a few hours, check the power saving settings on the phone. Some manufacturers (e.g. Xiaomi, Huawei) aggressively close the Mi Fit background processes, which prevents proper operation.

Method 2: Manually changing the time through the bracelet menu

Unlike newer models (like the Mi Band 5/6), the Mi Band 4 doesn’t directly access time settings via menus. However, you can get around this limitation with hidden developer mode or third-party utilities. The official way to manually set the time is through the app, but there’s a workaround:

1. Install Notify & Fitness for Mi Band (available on Google Play)
2. Connect the bracelet to the application and go to the Settings → More.
3. Activate the option Manual time synchronization and specify the desired hours / minutes.
4. Save the changes and wait for the vibration of the bracelet - this is a signal of successful setup.

⚠️ Note: Third-party utilities may conflict with official software. If after using Notify & Fitness bracelet stopped syncing with Mi Fit, reset it to factory settings (see section 5).

Method 3: Resetting the time zone on a smartphone

If the time on the Mi Band 4 differs by exactly 2-4 hours, the problem is most likely in the wrong time zone on the phone.

• 🌍 Traveling between countries with different belts.
• ✈️ Flying by plane (automatic belt definition can fail).
• 📵 Use two. SIM-Cards with different operators (some providers are forced to install their belts).

To correct:

1. On Android: Go to Settings → System → Date and time.
2. Turn off the option to automatically determine the time zone.
3. Select your belt manually (e.g. Moscow, GMT+3).
4. Return to Mi Fit and force the data to sync.

Method 4: Update the bracelet firmware

If none of these things worked, it could be because of outdated firmware. Xiaomi regularly releases updates for the Mi Band 4 to fix time synchronization errors.

1. Open the Mi Fit and go to the bracelet profile.
2. Slip on the three dots in the top right corner and select the firmware update.
3. If a new version is available, click Update and wait until it is completed (the bracelet will reboot).

⚠️ Warning: Do not disable Bluetooth or remove the bracelet from your hand during the upgrade. interruption of the process can lead to a blink (complete inoperability) of the device. If the update still gets lost, try to roll back to the previous version of the firmware using the utility Mi Band 4 Tools (requires root rights on the phone).

Method 5: Completely reset Mi Band 4 to factory settings

The last measure, hard reset, is applied if:

• 🔄 Time is lost every day despite all the manipulations.
• 📵 The bracelet is not synchronized with any phone.
• ⚡ After updating the firmware appeared glitches with the display of the clock.

Resetting instructions:

1. On the bracelet, go to Settings → About the device → Reset (swipe right 3 times, then tap the icon) ⚙️).
2. Confirm the action by clicking the tick.
3. After rebooting, connect the bracelet to the Mi Fit again, as when you first use it.

⚠️ Warning: Reset removes all data from the bracelet, including:

• 🏃‍♂️ Steps and training statistics.
• ⏰ Settings for alarm clocks.
• 🔋 Sleep data from the last 30 days.

💡

Factory reset is the most reliable way to get the time back, but only use it if other methods have not worked. Once reset, the bracelet will look like new, and you will have to configuring all over again.

Many users compound the problem over time on the Mi Band 4 by making common mistakes:

1. Ignoring Mi Fit Updates – Outdated versions of the app do not support new sync protocols.
2. Turning off the Mi Fit background in the battery settings – without background work, the app cannot update the time.
3. Use of "left" firmware - unofficial builds often contain time-displaying bugs.
