Changing a smartphone is always stressful, especially when a whole arsenum of smart gadgets is tied up in the Xiaomi ecosystem. Often users face a situation when they need to quickly transfer data and settings of a fitness tracker to a new device, but the process is not as obvious as you would like.
Just turning on Bluetooth on the new Redmi and expecting a miracle won't work -- the device can be locked by the previous pairing. To avoid losing training statistics, sleep and step data, and adjusting notifications correctly, it's important to do a series of sequential actions. It's critical to untie the device in the app on the old phone first before trying to connect it to the new one. Ignoring this step causes connection errors 90 percent of the time.
In this article, we will discuss in detail the algorithm for the owners of the Mi Home ecosystem, you will learn how to properly break the connection with an old gadget, clear the cache of Bluetooth services and re-authorize the tracker, which will save the activity history and ensure the stable operation of all functions on the new device.
Preparation of the old smartphone and uncoupling of the device
The first and most important step is to properly disable the bracelet from your old smartphone. Many users make the mistake of simply removing the app or turning off Bluetooth, leaving the device in limbo. First, open the Mi Fitness app (or Mi Fit if you use the older version) on the phone that the bracelet is connected to now.
Go to your device profile and find the menu item that manages the connection. The interface may vary slightly depending on the firmware version, but the logic remains the same. You need to initiate the disconnection procedure in a software way.
- 📱 Open the Mi Fitness app on your old phone and go to the Profile tab».
- ⌚ Click on your bracelet image in the list of devices to enter the control menu.
- 🔓 Select the “Unbind” or “Ununbind” option at the bottom of the settings list.
- ✅ Confirm the action in the pop-up window, waiting for the message of a successful shutdown.
Once the bracelet shows a detachment message (usually a vibration and an icon of a torn ring), you can go to the settings of the smartphone itself. Go to the Bluetooth system settings, find the tracker name (for example, Mi Smart Band 7) in your list of devices, and click “Forget the device” or “Steam” to ensure that the phone no longer tries to automatically connect to the bracelet.
⚠️ Note: If you simply remove the app from your old phone without untieing the bracelet, it may remain locked to connect to new devices, as Xiaomi servers will consider it active on your old account.
Now your tracker is fully ready to migrate. It's reset to factory pairing settings and awaits a new host. Don't turn on Bluetooth on your new phone yet to avoid search conflicts.
Setting up a new smartphone Redmi and installing software
Before trying to connect devices, you need to prepare the software environment on the new Redmi.Modern Xiaomi smartphones often come with the GetApps store already preinstalled, but for maximum compatibility, it is better to download apps from the official source of Google Play or the App Store.
Download and install the Mi Fitness app. This is the current platform for most new Xiaomi devices, including the Mi Band 6, Mi Band 7, Mi Band 8 and Watch series. If you have an older model, the system may suggest installing Zepp Life, but the new Redmi prefers a single ecosystem of Mi Fitness.
Once you install the app, launch it and log into your Mi Account. This is the key point: use the same account you had on your old phone if you want to recover your data history from the cloud. If you change your account, your workout history that wasn't synced before will be lost.
Turn on Bluetooth on your new smartphone. You can use the notification curtain or go to Settings → Bluetooth. Make sure the phone is visible to other devices. Don't try to pair through the Bluetooth system menu for now, this should be done strictly inside the application.
☑️ Checking before connection
The process of pairing the bracelet with a new phone
Now, the most important thing is to open the Mi Fitness app on your new Redmi. There should be a plaque on the home screen asking you to add a new device. If it doesn't show up automatically, click on the plus in the top right corner or go to the Devices tab.
The app will start scanning the space. Get closer to the bracelet to keep the signal stable. If the bracelet is in standby mode (the screen is on or reacting to touch), it should be determined in the list of available devices.
The bracelet screen and the smartphone screen will show confirmation codes, make sure they match, and confirm the pairing by pressing a button on the tracker's touchpad, which can take anywhere from 10 to 30 seconds, while keeping your phone away.
After a successful connection, the app will offer to update the firmware of the bracelet.It is strongly recommended to agree to an update if a new version is available, as this often fixes communication errors with new versions of Android on Redmi.
| Parameter | Meaning/Action | Importance |
|---|---|---|
| Distance | Less than 1 meter | Tall. |
| Bracelet charge | More than 20% | Medium |
| Android version | Android 6.0 and higher | Critical |
| Google Services | Active. | Tall. |
If you have a failed connection error, try restarting your smartphone and repeating the procedure, sometimes cleaning your Bluetooth cache, which we will discuss in the next section.
Solving detection and synchronization problems
Redmi owners may experience a situation where the phone does not see the bracelet, although it works properly on other devices, often because of the aggressive energy saving policies of MIUI or HyperOS, which kills the background processes of Bluetooth.
The first thing you need to do is check the permissions for the Mi Fitness app. Go to Settings → Apps → All apps → Mi Fitness → Application rights. Make sure you are allowed: location, Bluetooth, notifications and auto-run. Without geolocation permission, Android device search often doesn't work.
- 🔍 Enable precise location in the notification curtain.
- 🔄 Reboot the Redmi smartphone – it will reset the Bluetooth stacks.
- 🗑️ Clear the Mi Fitness app cache through the app management menu.
- 🚫 Turn it off. VPN antiviruses for the duration of pairing, they can block the local network.
Another common reason is having "junk" profiles in Bluetooth. Go to Bluetooth system settings, find all the old records about your previous trackers (even if they're already sold or lost) and delete them.The limit of saved devices sometimes overflows.
⚠️ Warning: If you can't see the bracelet anywhere, try charging it. Some models go into deep sleep mode when discharged and stop broadcasting Bluetooth signals before they're connected to the current.
It’s also worth checking if the bracelet is connected to a tablet or other phone in the house. Xiaomi smart devices can only connect to one active signal source for data transmission. If there is a device within a radius of 10 meters that the bracelet was previously associated with, it may try to connect to it as a priority.
Data recovery and account synchronization
Once you've successfully connected, the question of data arises. As we mentioned earlier, using the same Mi Account is key to success. When you first log in to an app on a new phone, the system will automatically tighten your cloud data. However, if you change your account region (for example, from Russia to Europe), the data may not sync.
You can check the region in the user profile in the app. If the regions are different, you will either need to change the region in your account settings (which can take up to 24 hours) or accept that the story will remain on the old server.
If you're switching from iPhone to Android (Redmi), the process is more complicated. Data from Apple Health doesn't transfer directly to Mi Fitness on Android. You'll have to use third-party converter apps or accept the start of new statistics. In the opposite direction (Android on iOS), migration is easier through account authorization.
Set up notifications and personalize on Redmi
The final step is fine-tuning. The new Redmis run on MIUI 13, 14 or HyperOS shells, which have their own notification features, and in order for the bracelet to vibrate when a message arrives, you need to not only allow it in the Mi Fitness app, but also in the system.
Go to Settings → Notifications and Status bar → Notification Management. Go to Mi Fitness and make sure the “Important” switch is on or pop-up notification is allowed. This will prevent the system from blocking messages.
You also need to set up a dial. You often change your phone and you have custom dials, and you go to the dial store and you can download the dial again, and you notice that some paid dials are tied to a particular device, and you have to re-purchase them or restore them through your purchase history.
Remember to set your activity goals. When you change your device or when you reset, your targets can go back to their standard values, adjust them to your current rhythm of life so that your motivation doesn't go away.
