Modern wearables like the Xiaomi Mi Band 2 have become an integral part of the lives of millions of users around the world.This activity tracker, released a few years ago, is still in demand due to its reliability and affordable price. However, like any electronic device, it requires the right initial setup to work properly all functions.
One of the most common problems that owners face after buying or resetting settings is the incorrect display of time on the screen. It is important to understand that the tracker itself does not have a built-in real-time clock with self-powered as usual, which means that without connecting to a smartphone, it will not be able to know what time it is.
In this article, we will take a closer look at synchronization, look at possible pairing errors, and answer questions that often come to mind for beginners: why Mi Fit doesn’t update time, how to force synchronization, and what to do if the numbers on the display keep lagging or show incorrect data.
There are several scenarios where you need to reset your time, which can be changing your time zone when you're traveling, switching to summer or winter time, and completely draining your battery, and each of these scenarios will be similar, but have different nuances that depend on your phone's operating system.
The principle of synchronization of time
The fundamental difference between the Xiaomi Mi Band 2 and the mechanical or more complex smart watches is the lack of a built-in GPS module and its own operating system that can independently receive data from the network. The time on the wristband screen is broadcast exclusively from the connected smartphone.
When you pick up your phone and unlock the screen, the Mi Fit app (or its current counterpart) automatically sends the data packet to the tracker. This packet contains not only the current time, but also the date, as well as information about alarm clocks and activity goals. If the application is not running or Bluetooth is disabled, synchronization is impossible.
It’s worth noting that the update delay can be anywhere from a few seconds to a couple of minutes.This is normal for Bluetooth Low Energy (BLE) technology, which is optimized to save battery life. A permanent connection doesn’t mean data is transmitted every millisecond; packets are exchanged when status changes or on schedule.
⚠️ Note: If you manually switched your watch on your smartphone, but the time on the wristband is the same, then the automatic synchronization didn't work. Don't try to change the time directly in the bracelet settings - there is no such feature there.
To work smoothly, you need to have geolocation services on your phone, which is a requirement of Android and iOS to work with Bluetooth scanning. GPS-module (even if navigation is not used) the application may not see the bracelet and, accordingly, will not be able to update the time.
Step-by-step instructions for Android
Owners of Android devices are lucky with the wide customization options, but the number of potential conflicts here is higher. First of all, make sure you have the official Mi Fit app installed or its modern counterpart Zepp Life. Older versions of the software may not work properly with new versions of Android.
The setup process starts with checking permissions. Android often limits the background work of applications to save energy, which can block the transfer of time. You need to find the application in the phone settings and allow auto-start and work in the background.
☑️ Checking Android settings
Once you open the app, go to Profile tab and select your bracelet. In the menu that opens, look for the bracelet settings. Here, you can see the current time the app sees. If it differs from the real time, the problem lies in the settings of the phone itself.
For forced synchronization, pull down the list of devices or press the update button. The screen of the bracelet should light up and the numbers will change. If that doesn't happen, try rebooting Bluetooth on the phone: turn off and turn on again.
It is important to check the time format. In some regions, the app may offer a 12-hour or 24-hour format. Changing this setting in the bracelet settings application → The time format will immediately affect the tracker screen.
Setting time on iPhone (iOS)
Users of the Apple ecosystem face stricter iOS security policies: Here, the time synchronization process on the Xiaomi Mi Band 2 is closely tied to Bluetooth resolutions and notifications. Unlike Android, iOS doesn't allow apps to get so deeply embedded that it sometimes causes delays.
The first step is to check the system time of the iPhone. Make sure that the settings Main → Date and time is ticked Automatic. If the time on the phone is knocked, the bracelet will get the wrong data. iOS rarely makes mistakes if synchronization is enabled over the network.
The Mi Fit app on iOS requires constant access to Bluetooth. If you see a message that the connection is lost, there will be no time to update, in which case close the application completely (swipe up) and run it again.
The feature of iOS is that data updates often only occur when you are actively using the application. Just having a process running in the background may not be enough to instantly transfer time data if the system decides to “fall asleep.”
⚠️ Note: iPhones cannot be set alarm clocks or manually through third-party utilities outside the Xiaomi ecosystem. Use only official apps to avoid out-of-synchronization.
If after all the manipulations, the time on the bracelet is behind, try to turn off the bracelet in the application (Stop button) and reconnect it. This forcibly initiates a full exchange of data, including time stamps.
Solving problems with desynchronization
The situation when the time on the wristband and phone is constantly different is the most common complaint of users, which can be caused by a software failure, and the peculiarities of the Bluetooth protocol on a particular device.
One reason could be that the operating system has frozen the backgrounds. The smartphone thinks the Mi Fit app has been out of use for a long time, and it stops it from working to save battery power. As a result, when you look at the wristband, it shows the time of the last successful synchronization, which could have been a few hours ago.
To solve this problem, you need to add an app to the list of power saving exceptions. On different phone models (Samsung, Xiaomi, Huawei), this item is called differently: "Start", "Battery", "Optimization". Find the application in the list and select "No restrictions" mode.
Another reason for the desynchronization could be a memory overflow of the bracelet. Although the Xiaomi Mi Band 2 has modest specs, an event buffer overflow can block the transfer of new data, including time, in which case a complete reset of the device helps.
Also worth checking is the firmware version of the tracker itself. Go to the app, select the bracelet, and find the Update Checker. The outdated version of the software may contain bugs that have been fixed in newer releases.
Complete reset and reconnect the device
If no methods help and time continues to float away, the radical but effective method is a complete reset, which will return the device to factory settings and clear up all the accumulated errors.
To perform a reset on Xiaomi Mi Band 2, you need to find a tiny hole or button on the device body (usually on the back, under the strap), pressing it for 5-10 seconds will cause the image to vibrate and disappear on the screen, after which the bracelet must be reconnected to the phone as a new device.
| Problem. | Possible cause | Decision |
|---|---|---|
| Time is 1-2 hours behind | Incorrect time zone in the app | Check the region settings in Mi Fit |
| Time is not updated at all. | Background blocking | Allow auto-launch of the application |
| The screen does not light up when synchronized. | Bracelet battery discharged | Put it on charge. |
| Format is lost (AM/PM) | Phone settings conflict | Change the format in the bracelet settings |
Once you pair it again, the app will ask for all the permissions that you need, and at that point, it's critical to not miss Bluetooth and geolocation requests, and without them, you can't work properly.
The initial setup process after reset takes a few minutes, wait until the progress bar reaches 100%, and then check the readings on the tracker screen.
