Xiaomi Mi Band 4 remains one of the most popular fitness bracelets even years after its release. However, many users face the problem: the time on the wristband screen does not match the real one or gets lost after disconnecting from the smartphone. In this article, we will analyze all the current ways of setting time, from automatic synchronization through the application to manually fixing time zones and solving typical errors.
It is important to understand that the Mi Band 4 has no own GPS-It is completely dependent on the data of the smartphone, which means that any inaccuracies in the phone settings (incorrect time zone, disconnected time synchronization over the network) are automatically transferred to the bracelet. We will look not only at the basic instructions, but also at the hidden nuances – for example, why time can be “lagging behind” on the basis of the basic rules. 3-5 minutes, even with the correct settings.
This article is relevant for all Mi Band 4 firmware versions (including the latest 1.0.9.54) and compatible with Mi Fit (obsolete) and Zepp Life (recommended).
Why Mi Band 4 is the wrong time: the main reasons
Before you start setting up, it's important to identify the root of the problem, and 80 percent of the time inaccuracies are not related to the bracelet, but to the settings of your smartphone or app.
- 📱 Incorrect time settings on the smartphone: if the phone is disabled automatic synchronization over the network (Settings) → System system → Date and time, the bracelet will copy the erroneous data.
- 🌍 Wrong time zone: Even with automatic synchronization enabled, some smartphone firmware (especially custom ones) can detect an error belt.
- 🔄 Synchronization failures in Mi Fit/Zepp Life: the application could “hang” on old data or lose communication with Xiaomi servers.
- 🔋 Low battery power: At a charge level below 10%, the Mi Band 4 can pause background processes, including time updates.
- 📲 Outdated version of firmware: in early versions of the bracelet software (below 1.0.8.12) there was an error with the “sticking” of time after the reboot.
A critical feature of the Mi Band 4 is that the bracelet does not store time in non-volatile memory, which means that when the clock is completely discharged or reset, it resets to January 1, 2000 and requires re-synchronization. Unlike newer models (for example, the Mi Band 6), there is no backup power source for storing data.
If your bracelet shows exactly 3-4 hours apart, it’s likely a time zone problem. For example, Moscow Time (UTC+3) may conflict with the settings of an application that defaults on UTC+0. The solution is to manually tie the bracelet to the correct region (more on this below).
Method 1: Automatic time synchronization through Zepp Life (recommended)
The most reliable method is to use the official Zepp Life app (formerly Mi Fit), which automatically updates the time on the wristband every time you connect to Bluetooth.
- Install or update Zepp Life: 📥 Download the app from Google Play or App Store. 🔄 Update it to the latest version (at 2026 6.12.0 or later).
- Put the bracelet on: 🔗 Start Zepp Life and go to Profile → My devices. → Add the device. 📱 Select Mi Smart Band 4 from the list and follow the instructions on the screen.
Turn on automatic synchronization
- ⚙️ Go to Profile. → Mi Smart Band 4 → Settings of the device → Synchronization of time.
- 🔄 Make sure that the slider Autosynchronization is active (blue color).
What if the bracelet does not connect after resetting?
Solving specific time problems on Mi Band 4
Some of the time errors are unique to the Mi Band 4 and are not found in newer models. Let's look at the most common cases and their solutions.
Problem 1: Time is lost after disconnecting from the phone
If the bracelet shows the correct time only when connected to the smartphone, and after disconnecting “lagging behind” or resets, the reason is one of the following:
- 🔋 Low battery power (less than 15%) – the bracelet goes into power saving mode and suspends the time update.
- 📴 Failures in the Bluetooth module – the bracelet does not have time to synchronize data before the connection breaks.
- 🕒 Outdated firmware – versions below 1.0.8.12 had a bug with “forgetting” time.
