How to Set and Sync Time on Xiaomi Fitness Bracelet: From Mi Band 3 to 8

Xiaomi fitness bracelets are some of the most popular wearables on the market due to their combination of functionality and affordable price. However, even simple operations such as time setting sometimes raise questions from users. The time on the wristband can get lost after discharging, resetting or moving to a different time zone. In this article, we will discuss all the ways to synchronize time on models from Mi Band 3 to Mi Band 8, including solutions to typical problems.

It’s important to understand that Xiaomi fitness bracelets don’t have their own interface for manual time entry – it syncs automatically with your smartphone via an app. However, there are nuances from enabling automatic synchronization to manually adjusting through hidden settings. We’ll look at both options, and also explain why time may be displayed incorrectly and how to fix it.

What Xiaomi models support time synchronization?

All modern Xiaomi fitness bracelets automatically tighten the time from a smartphone, but the ways of setting up differ depending on the model and firmware version. Below is a brief overview of supported devices:

• 🔹 Mi Band 3/4 — synchronization via Mi Fit (an outdated application, but still relevant for older models).
• 🔹 Mi Band 5/6 — Mi Fitness and Zepp Life support (recommended for the latter).
• 🔹 Mi Band 7/8 — only Zepp Life, with advanced time zone settings.
• 🔹 Xiaomi Smart Band 7 Pro is similar to Mi Band 7 GPS-Module (time may be lost less often).

If you have a model older than the Mi Band 3 (like the Mi Band 2), time synchronization works differently — via Bluetooth Low Energy (BLE) without attachment to the application.

Preparation before setting the time

Before you start synchronization, make sure that the basic conditions are met:

Smartphone connected to the Internet (Wi-Fi or mobile network)

Bluetooth enabled and geodata permission for Zepp Life/Mi Fitness app

Bracelet charged at least 20% (at low charge synchronization may not work)

The latest version of the application is installed (updates often fix bugs over time)

-->

Pay special attention to app permissions. On Android 12+ and iOS 15+, systems actively block access to geodata and background, which can interfere with automatic synchronization. For example, if you disabled Permanent Location for Zepp Life, the bracelet will not be able to determine the time zone.

⚠️ Attention: On iPhone with iOS 16+ When you update your system, you sometimes lose Bluetooth settings for wearables. If the time on the bracelet stops updating, try forgetting the device in your Bluetooth settings and reconnecting it.

Method 1: Automatic synchronization via Zepp Life (recommended)

Since 2022, Xiaomi has moved to the Zepp Life app (formerly Mi Fit) for all new bracelet models, and the interface and synchronization algorithms are better optimized than in the older versions.

1. Open Zepp Life and make sure the bracelet is plugged in (the Bluetooth icon at the top of the screen must be active).
2. Go to Profile → Your Device → Device Settings.
3. Find the date and time (in some versions, time synchronization).
4. Activate the Automatic Synchronization switch.
5. The synchronization is complete (usually takes 5-10 seconds).

If the date and time item is missing, your bracelet model syncs the time automatically every time you connect to your phone.

• 📱 On the smartphone, the automatic date and time are included (in the system settings).
• 🌍 Geodata permission for Zepp Life (required for time zone determination).
• 🔄 Reset the bracelet (press the touch button for 10 seconds before vibration).

💡

If the bracelet time is a few minutes behind, try manually updating the device’s firmware through Settings → In-app software updates. This often solves the problem of inaccurate time.

Method 2: Manually update time via Mi Fitness (for older models)

If you have a Mi Band 3/4/5 and you use an outdated Mi Fitness app, the process is a little different. There's no separate time synchronization unit here, it updates every time you connect to your phone.

1. Open Mi Fitness and wait for the bracelet to connect.
2. Pull the screen down to update the data (swipe down gesture).
3. If the time is not updated, go to Profile → Your device → Additional settings.
4. Choose Sync Data and wait for the process to be completed.

For Mi Band 4 and older, Mi Fitness sometimes has a bug when time is lost for 3-4 hours, due to incorrect processing of time zones.

⚠️ Note: If the time on the bracelet differs by exactly 3 hours after synchronization (for example, it shows 15:00 instead of 18:00), check the time zone settings on your smartphone. In some regions (for example, Moscow), automatic transition to winter/summer time may conflict with the firmware of the bracelet. Turn off this option in your phone settings.

Solving the Wrong Time Problem

If the time on the wristband is lost or not updated, the reasons can be both software and hardware. Let's consider the most common scenarios and how to fix them.

1.Time is strayed after discharge

Xiaomi bracelets (except Mi Band 8) use non-volatile memory to store time, but with full battery drain (below 1%), the watch can reset.

• 🔋 Charge the bracelet to 100% and wait for automatic synchronization.
• 📲 Reconnect the device in the application (profile) → Your device. → Disconnect/Connect).
• ⚡ If the problem recurs, update the bracelet firmware.

2.Time is behind or hastens for a few minutes

This is typical of a Mi Band 6/7 with outdated firmware. An internal quartz generator can give an error of up to ±2 minutes per day.

• 🔄 Update the firmware through Zepp Life.
• 📡 Forced synchronization of time (see Method 1).

3. the time zone does not correspond to the real

This problem arises if:

• 🌐 On the smartphone disabled the option Automatic time zone.
• 📍 Zepp Life app banned from accessing geodata.
• ✈️ You recently moved to another region, but the bracelet has not updated the data.

Solution: Manually set the correct time zone on your phone or reset the bracelet (press the button for 15 seconds).

💡

If the bracelet shows the time of another city, first check the time zone settings on your smartphone – this is where the data is taken for synchronization.

Additional settings: time format and alarm clocks

In addition to the main time, Xiaomi bracelets can be configured:

• 🕒 12/24-hour format - changes in bracelet settings through the application.
• 🔔 Alarm clocks – up to 10 pieces with vibration (tuned in Zepp Life) → Alarm clocks).
• 🌙 Do Not Disturb – Turns off notifications and alarms at a given time.

To change the format of the time:

1. Open Zepp Life and select your bracelet.
2. Go to the device settings → Display and brightness.
3. Find the time format and choose 24-hour or 12-hour.
4. Save the changes and wait for the synchronization.

The Mi Band 8 also has an automatic format switching option based on the region (for example, the default format will be 12-hour in the US).

Frequent Mistakes and How to Avoid Them

Many users experience the same time setting problems, and here are the most common errors and ways to prevent them:

• 🚫 Ignoring firmware updates – outdated software often contains synchronized bugs. Always update the bracelet via Zepp Life.
• 🚫 Disabling geodata for the application – without access to the location, the bracelet will not be able to determine the time zone.
• 🚫 Use of informal firmware – custom versions (such as Mi Band Master) can break time synchronization.
• 🚫 Discharge the bracelet to zero, which causes the internal clock to reset. Charge the device at 10-15% charge.

On the Mi Band 7 and later, it syncs not only with your smartphone, but also with Xiaomi servers over the Internet, which means that even if your phone shows the wrong time (for example, after manual settings), the bracelet can pull the correct data from the servers, but it requires a stable connection to the network.

⚠️ Note: If you use the Mi Band with two smartphones (e.g., a work and a personal), time may be lost due to a synchronization conflict.
