How to set up time on Xiaomi Mi Band 4 without a smartphone: all working methods

The Xiaomi Mi Band 4 fitness bracelet is one of the most popular wearables due to its combination of functionality and affordable price. However, many users are faced with the problem: how to update the time on the watch if there is no smartphone at hand? The standard way through the Mi Fit or Zepp Life application requires constant synchronization, but what to do on the trip, with a discharged phone or if the bracelet is bought using a used one without a tether?

In this article, we’ll look at all the possible ways to manually adjust time on the Mi Band 4 without using a smartphone, from hidden menu features to hardware resets, and why watches can show the wrong time even after synchronization, and how to fix it. Instructions are suitable for all versions of firmware, including Chinese (CN) Global (Global) Bracelet Modifications.

Important: Some methods require prior preparation, such as activating a hidden developer mode or using third-party tools, and we will describe each step in detail so that you can choose the most convenient option.

Why does Mi Band 4 have a time without a phone?

Xiaomi Mi Band 4 bracelet is not equipped with its own GPS-A module or module that automatically synchronizes time over the network (as opposed to a smart watch), the time on it is updated only when connected to a smartphone via Bluetooth, and if communication is interrupted for a long time, the clock begins to "go" forward or backward due to the inaccuracy of the built-in quartz generator.

The main reasons for the failure of time:

• 🔋 Battery discharge below 10% – the bracelet goes into energy-saving mode, which can knock down the internal clock.
• 📡 Long-term lack of synchronization (more than 2-3 days) - the error accumulates at a rate of ~1-2 minutes a day.
• 🔄 Resetting settings or updating firmware without tethering to the phone.
• 🌍 Time zone change – the bracelet does not automatically adjust the time.

Interesting fact: the firmware of the Mi Band 4 before version 1.0.9.54 had an error that reset the time when the battery was low. In the newer versions, the problem is partially fixed, but the error still remains.

Method 1: Manually adjusting time through hidden menu

Few people know, but the Mi Band 4 has a hidden engineering menu that allows you to manually adjust the time without the phone, which works on all versions of the bracelet, but requires accurate execution of steps.

Instructions:

1. On the main screen of the bracelet, swipe your finger up and down 5 times quickly (as when scrolling the menu).
2. After the vibration, you will see a screen that says TEST, which is an engineering menu.
3. Scroll down to Time Set (or the Chinese version) and tap it.
4. Use swipes left/right to select hours and minutes, tap to confirm.
5. After setting up, press and hold the screen for 3 seconds to save.

Important: if the time is lost again after saving, then the bracelet has activated the "Auto-Sync by GPS" mode (although the GPS module itself is not in the Mi Band 4). To turn it off, find the GPS Sync item in the engineering menu and deactivate it.

Stock up on the bracelet charge (minimum 30%)

Make sure there are no notifications on the screen (swipe them aside)

Use a clean finger (mud can interfere with the sensor)

Do not interrupt the process until confirmation vibrations.-->

Method 2: Synchronization through third-party software (without a phone)

If you have access to a computer or tablet, you can use alternative time-setting software, such as the Mi Band Master utility (formerly Mi Bandage) that allows you to control the bracelet via a Bluetooth adapter.

Step-by-step instructions for Windows:

1. Download and install Mi Band Master (version 4.7.1 or later).
2. Turn on Bluetooth on your computer and disconnect your phone from the bracelet (to avoid conflict).
3. Start the program, select Connect a new device → Mi Band 4.
4. In the Time Settings section, check the manual synchronization box and enter the current date/time.
5. Press Sync and wait for the vibration of the bracelet.

Advantages of the method:

• ✅ Accuracy to a second.
• ✅ Ability to configure time zone and display format (12/24 hour).
• ✅ It works with Chinese versions of the bracelet (CN).

⚠️ Note: When using Mi Band Master, disable antivirus – some versions of the program are mistakenly identified as malicious due to working with Bluetooth stack.

Method 3: Hardware reset and re-binding

If the bracelet shows a completely wrong time (for example, January 1, 2000), this is a sign of a firmware failure, in which case a complete reset of the settings and subsequent manual adjustment will help.

How to make a hard reset:

1. Disconnect the strap from the bracelet body.
2. On the back, find a small hole with the inscription RESET.
3. Take a paper clip or pin and press the button inside the hole for 10-15 seconds until you feel the vibration.
4. The bracelet will reset and return to factory settings (time will be reset by 00:00 1.01.2019).

After discharge:

• 🔄 Use Method 1 (Hidden Menu) to manually adjust.
• 📱 If possible, tie the bracelet to your phone for 5 minutes for automatic synchronization, then untie.

⚠️ Warning: Hardware reset removes all the data from the bracelet: steps, sleep history, alarm clocks. If you care about statistics, pre-synchronize it with your phone.

Method 4: Use of a second device (Android/iOS)

If you don't have your own smartphone, but you have access to someone else's Android/iOS phone, you can temporarily tie the bracelet to synchronize time, which doesn't require you to install apps on your main phone.

Instructions for Android:

1. Download the Hearty Pro app (an alternative to Mi Fit without linking to your account) to someone else's phone.
2. Turn on Bluetooth and connect the bracelet via Add Device → Mi Band 4.
3. In the Bracelet Settings section, find Time Synchronization and activate it.
4. After updating the time, untie the bracelet in the application settings.

For iOS:

• 📱 Use Mi Fit, but log in under the guest account (click Skip when requesting login).
• 🔄 Sync the time, then delete the app – the bracelet will save the settings.

💡

If you don't have access to your phone, but you have an Android tablet, use it -- the connection algorithm is the same. As long as the device has a Bluetooth 4.0 version or a newer one.

Solving the Problem: Time is Stuck Again

If after manually setting up the time on Mi Band 4 continues to "go away", check the following points:

Reason 1: Battery discharged

When charged below 15%, the bracelet goes into energy saving mode, which can knock down the internal clock. Charge the device to 100% and re-set.

Reason 2: Firmware conflict

If you have updated the bracelet through third-party firmware (such as Amazfit or Custom FW), they may contain synchronization errors.

Reason 3: Hardware defect

In rare cases, a faulty quartz resonator (responsible for counting time) is to blame.

• 🕒 Time's going to be 10.+ minutely.
• 🔄 Resetting doesn't help.
• 🔋 Bracelet discharges quickly.

Solution: contact the Xiaomi service center (if the warranty is valid) or replace the fee yourself (cost ~ 500-800 rubles).

💡

If the bracelet knocks time down by 1-2 minutes a day, this is a normal error of the quartz generator.
