Xiaomi Mi Band fitness bracelets (from Mi Band 2 to Mi Smart Band 8) automatically synchronize time with a connected smartphone, but sometimes manual adjustment is required - for example, after a reset, battery change or firmware failure. Incorrectly tuned watches lead to errors in sleep data, training and notifications. In this article, we will discuss all ways to adjust time, including hidden functions and solutions to typical problems.
It is important to understand that the synchronization algorithm depends on the firmware version of the bracelet and the Mi Fitness app (formerly Mi Fit). The latest version of the application (2026) supports automatic time zone adjustment, but older models (Mi Band 3/4) may require manual intervention.
Why is the Xiaomi Mi bracelet the wrong time?
If the Mi Band watch is in a hurry, lags behind, or shows an incorrect date, the reasons fall into three categories:
- 📱 Smartphone problems: incorrect time settings/dates on the phone, disabled network synchronization, outdated version of the Mi Fitness app.
- 🔄 Synchronization failures: the bracelet is not connected to the phone via Bluetooth, conflict with other applications (for example, Google Fit or Zepp).
- ⚙️ Hardware or software errors: discharged battery, damaged firmware, failure after update.
For example, Mi Band 5 and later can “hang” on the last sync time if the Bluetooth on the phone turned off before the bracelet had time to update the data. and Mi Band 4 is known bug with automatic time reset at a low charge below 5% – this is officially confirmed problem that Xiaomi did not fix in old firmware.
Automatic time synchronization with the phone
By default, the Xiaomi Mi bracelet synchronizes time with the connected smartphone.
- Make sure the phone is on: 📶 Automatic date and time (in system settings). 🔵 Bluetooth and geodata permission for Mi Fitness.

What if your time zone is not on the list?
On Mi Band 4 and below, the time zone is tied to your phone and does not adjust separately.If you are traveling, temporarily turn off automatic sync and set local time manually.
Solving time disruption problems
If the time on the bracelet is knocked down regularly, check the following points:
- 🔋 Battery charge: below 10%, the bracelet can reset settings. Charge it to 100% and sync again.
- 📲 App conflict: Remove other fitness trackers (like Google Fit or Huawei Health) that may block Mi Fitness from accessing data.
- 🔄 Outdated firmware: update the bracelet through Profile → My devices. → Update of the PO.
For Mi Band 3/4 with constant time failures, resetting to factory settings will help:
- On the bracelet, go to Settings → Reset (or Additional → Reset).
- Confirm the action and wait for the reboot.
- Re-couple the bracelet with your phone through Mi Fitness.
⚠️ Warning: After reset, all steps, sleep and training data will be deleted. To save the statistics, export it to Mi Fitness before reset (Profile section) → Health data → Exports).
💡
If the bracelet shows a latency (e.g., it updates once an hour), check your phone's energy saving settings. On Android, add Mi Fitness to the battery optimisation exception list.
Features of setting time on different models
Each generation of the Mi Band has unique nuances of time synchronization:
- 🆕 Mi Smart Band 8: Supports automatic time zone determination GPS (if the module is enabled in the settings).
- ⏱️ Mi Band 7: May be 1-2 minutes behind due to energy savings.Credited by power-saving switching off in bracelet settings.
- 🔄 Mi Band 5: Manual time setting requires confirmation via Mi Fitness (pop-up).
- ⚡ Mi Band 4: After Updating to 1.0.9.54, You Can Reset Time When Connecting to a New Phone.

- Remove the bracelet from Mi Fitness (Profile → My devices → Delete).
- Reboot your phone and bracelet.
- Connect the device again, pre-enable flight mode on the phone for 30 seconds (resets the Bluetooth cache).
How to check the accuracy of time on the bracelet?
To make sure that the time on the Xiaomi Mi Band is synchronized correctly:
- Compare the bracelet readings with the exact time on your phone (use time.is to check).
- Run the stopwatch simultaneously on the bracelet and phone - a delay of more than 2 seconds indicates a failure.
- Check the date display: if the bracelet shows yesterday, then the sync is blocked.
To test automatic synchronization:
- Change the time on your phone manually (e.g., set +1 hour).
- Wait for synchronization (usually takes 1-3 minutes).
- If the bracelet has not updated the time, reconnect it via Mi Fitness.
