How to find the lost Xiaomi Mi Band 4: all the ways from official to non-standard

Losing the Xiaomi Mi Band 4 is an unfortunate situation, especially if the bracelet was your daily assistant in tracking activity, sleep and notifications. Fortunately, this gadget has several features that increase the chances of its return. GPS-It doesn't mean that you can't track them, but in this article, we'll go through all the working methods of searching, including the little-known tricks with the Mi Fit app, the use of Bluetooth scanners, and even social engineering to return the device.

It's important to understand that success depends on whether the bracelet is on, whether it's in range of your smartphone or other devices, and whether someone has dropped it to the factory settings. If the battery runs out (and the Mi Band 4 keeps the charge up to 20 days), the odds drop dramatically. But don't despair - even then there are ways to return the gadget or at least save your data.

So we'll start with the simplest and most obvious steps, and then we'll go to the more complex methods.

1. Check out the last known location in Mi Fit

The first thing you need to do is open the Mi Fit app (or Zepp Life if you switched to it) and check your sync history, and even if the bracelet isn't connected now, the app could save data about the last successful connection.

How to do this:

📱 Open Mi Fit and go to the Profile tab → My devices. → Mi Smart Band 4.
🔍 Scroll down to the Last Sync section, where you will find the time and possibly approximate location (if you have geolocation enabled in your smartphone).
📍 If you are using Android, check your settings. → Google → Location history – there may be a mark of the last bracelet connection to the phone.

The Mi Band 4 is not broadcasting. GPS-It relies on the data of the smartphone, so if the phone wasn't with you at the time of the loss, it won't work, but if the bracelet is lost at home or at work, the sync history will help narrow the search area.

💡

If you've been syncing your data regularly with Mi Fit, try to remember where your steps or pulse was last updated, often close to where the bracelet is.

2. Use the "Find Device" function in Mi Fit

Xiaomi Mi Band 4 has a built-in audible alert feature that helps you find the bracelet if it is within Bluetooth range (up to 10 meters in ideal conditions).

Step instructions:

Open the Mi Fit app.
Select your Mi Band 4 from the device list.
Tap on three points (⋮) top-right.
Select the item Find the device.
The bracelet will begin to vibrate and emit an audible signal (if it is on and in range).

If the bracelet does not respond:

🔋 Make sure it is charged (try bringing it to the charger – if the indicator lights up, it means the battery is not discharged).
📶 Check if Bluetooth is on and there are no interferences (other devices, walls, metal objects).
🔄 Reboot the Mi Fit app or smartphone.

3. Check connected devices via Bluetooth

If the bracelet is still on but is out of range of your main smartphone, you can try to detect it through other devices, such as a tablet, second phone, or even a Bluetooth laptop.

Open Settings → Connected devices → Bluetooth.
Check out the list of Connected Devices – if the Mi Band 4 is there, it’s somewhere nearby.
If the device is not paired, click Scan and search in the list MI Band 4_XXXX (where XXXX — unique identifier).

On the iPhone:

Go to Settings → Bluetooth.
Check out the My Devices section.
If the bracelet isn’t displayed, try turning Bluetooth on and off – sometimes it helps detect hidden devices.

You can also use specialized applications to scan Bluetooth devices, such as:
