Synchronizing Xiaomi devices: from phone to smart home

Xiaomi devices are famous for their ecosystem, where smartphones, smartwatches, fitness bracelets, speakers and even appliances can communicate in real time. However, not all users know how to properly configure this synchronization to avoid data loss or conflicts between gadgets. In this article, we will analyze all the ways of synchronization, from basic binding to Mi Account to fine-tuning for specific models.

The main problem faced by Xiaomi owners is the fragmentation of data, such as steps with the Mi Band 7 do not appear in the Mi Fitness app on the phone, or photos with the Redmi Note 12 do not load automatically into the cloud, the reasons can be due to both incorrect account settings and firmware version conflicts, we analyzed official guides, user feedback and technical forums to collect relevant solutions for 2026.

We will focus on three key scenarios: (1) Smartphone and wearable device synchronization (Mi Band, Watch); (2) Phone-Mi Home data exchange; and (3) Backup and Recovery via Mi Cloud.

For each case, we give step-by-step instructions taking into account the latest updates. MIUI.

1.Preparation: Create and configure Mi Account

Without a Xiaomi account, device synchronization is impossible. Even if you use your gadgets locally (for example, connect the Mi Band directly to your phone over Bluetooth), you will need a Mi Account to back up and share data between multiple devices.

To create an account:

• 📱 Open on your smartphone Settings → Xiaomi Account (or Settings) → Memory and backup copies → Backup in new versions MIUI).
• 🔄 Click on “Create an account” and follow the instructions. Specify a valid email (preferably Gmail, it has less problems with recovery).
• 🔐 Enable two-factor authentication in your account settings – this will protect your data when synchronized.
• 🌍 Select the region “Russia” (or your country), as it depends on the available services (for example, Mi Home in China and the global version differ).

If you already have an account, but your devices are not synced:

1. Check that all devices use the same Mi Account (sometimes users create multiple accounts by mistake).
2. Update your Mi Fitness, Mi Home, and Mi Cloud apps to the latest versions on Google Play or the App Store.
3. In the phone settings go to Settings → Annexes → App management, find Xiaomi apps and clear the cache.

⚠️ Note: If you used Chinese firmware on your smartphone, and then searched for a global one MIUI, The old Mi Account may not work, in which case, create a new account and manually transfer the data through export/import.

2.Sync smartphone with Mi Band or Mi Watch

Wearable devices Xiaomi (Mi Band) 6/7/8, Watch S1/S2, Watch 2 Pros are synced to a smartphone via the Mi Fitness app (formerly Zepp Life), but many users find that steps, sleep or pulse data are not updated.

Step 1. Check the connection

• 🔗 Make sure your phone has Bluetooth and geolocation enabled (without it, some features, such as sleep tracking, don’t work properly).
• 📲 In the Mi Fitness app, go to Profile → My devices and check the status of the connection. If there's an exclamation mark next to the bracelet name, click on it and re-sync it.
• 🔄 If the bracelet is not identified, remove it from the list of devices and add again (to do this, click “Add device” and follow the instructions).

Step 2: Set up automatic synchronization

By default, the data from the wristband should be synced automatically every 30 minutes.

1. Open Mi Fitness → Profile → Settings → Data Synchronization.
2. Enable the Autosynchronization option and set the interval (30 minutes is recommended).
3. Check that the phone settings for the Mi Fitness app allow auto-start and work in the background (Settings) → Annexes → Permits → Auto-start).

Step 3: Solving Data Problems

If the steps or pulse are not displayed in the appendix:

• 📊 Check that activity tracking is enabled on the bracelet (Bracelet settings) → Monitoring of the heart/steps).

5. Synchronization between several Xiaomi smartphones

If you have multiple Xiaomi phones (such as a work phone and a personal phone), they can be synchronized so that data is duplicated on both devices, which is convenient for backing up or sharing contacts, photos and notes.

Method 1: Through the Mi Cloud

The easiest way to do this is to use the cloud:

1. On both phones, log in to the same Mi Account.
2. Enable synchronization of the required data (Settings) → Mi Cloud).
3. Wait until the sync is complete (it can take up to several hours if there are many photos).

Method 2: Local synchronization over Wi-Fi Direct

If you don’t want to use the cloud, you can transfer data directly to:

• 📲 On the first phone, open the Gallery or Contacts, select files and click “Send».
• 🔗 Select the option “Wi-Fi Direct” or “Transfer to Xiaomi device».
• 📱 On the second phone, confirm the data reception.

Method 3: Through the app "Cloner" (Mi Mover)

Mi Mover app (built-in in the MIUI) It allows you to transfer data between Xiaomi phones without the cloud:

1. On both phones, install Mi Mover (if not, download from Google Play).
2. On the old phone, select “I give” and on the new one, “I receive.”
3. Scan it. QR-code and select data for transfer (contacts, SMS, photos, applications).

• ❌ System settings (wallpaper, sounds, brightness) - not synchronized.

💡

To sync between phones, make sure to use the same Mi Account. If the accounts are different, the data will not be duplicated automatically, even if the phones are connected to the same Wi-Fi network.
