Step-by-step connecting Xiaomi smart watches to Android via Bluetooth: from pairing to settings

Xiaomi’s smartwatch has long since ceased to be just an accessory — it has become a full-fledged assistant for monitoring health, managing notifications and even paying for purchases. But before using all these features, you need to connect the device correctly to your smartphone. Despite the apparent simplicity of the process, many users face pairing errors, synchronization problems or incorrect sensors after connecting.

In this article, we will discuss all the steps of connecting Xiaomi smart watches to Android via Bluetooth, from preparing devices to fine-tuning notifications and solving typical errors. Particular attention will be paid to the Mi Band 8, Xiaomi Watch S3, Watch 2 Pro and Redmi Watch 3, because their firmware have key differences. If you previously tried to connect the watch, but encountered the message “failed to find the device” or “Sync error”, here you will find proven solutions.

Preparation of the smartphone and watch for pairing

Before you start connecting, make sure both devices are ready to go, which will save you most of the errors in the search and pairing phase.

On the smartphone side:

• 📱 Update Android to the latest version (minimum Android 8.0 for stable work with Mi Fitness). → The phone. → Updating the system.
• 🔄 Activate Bluetooth and geolocation (the latter for accurate activity tracking). → Connections → Bluetooth and Settings → Confidentiality → geodata.
• 🚫 Turn off the power saving mode for the Mi Fitness app (or Zepp Life for new models) or sync will be interrupted.

On the smartwatch side:

• 🔋 Charge the device to at least 50%. Low charge can interrupt the pairing process.
• 🔄 Reset if the watch has already been connected to another phone. To do this, press the button (or touch zone) for 10-15 seconds before the appearance of the Xiaomi logo.
• 📦 Make sure it’s compatible.For example, Xiaomi Watch 2 Pro requires Android 9.0+, Mi Band 7 works on Android 6.0.

⚠️ Note: If you use custom firmware (like LineageOS), pre-check Bluetooth 5.0 support+. Some assemblies block pairing with wearable devices.

Installation of the official application: Mi Fitness or Zepp Life?

The key is choosing the right app. Xiaomi is gradually moving all devices to the Zepp Life platform, but some models (such as the Mi Band 6) are still supported through Mi Fitness. An error in choosing an app will lead to the fact that the watch is simply not determined by the system.

How to determine which application you need:

Download the application from official sources:

• 🌍 Google Play: Mi Fitness or Zepp Life.
• 📱 APK-File: Only from APKCombo (check your model version!).

⚠️ Note: Do not use app clones (such as Mi Fit Pro or Amazfit) not only will they not connect the watch, but they can also steal your Xiaomi account details.

💡

If you have Xiaomi Watch S3, remove Mi Fitness before installing Zepp Life – the application conflict blocks synchronization.

Step-by-step: pairing the clock with Android via Bluetooth

Now, to the process of connection, follow the instructions strictly by step, and even one point can be missed.

Step 1. Enable the pairing mode on the watch:

Setup of notifications and data synchronization

Once you've successfully connected, you need to configure what notifications will come to the clock and how often you'll sync, and by default, many of the functions are disabled to save battery life.

How to enable notifications:

1. In the app, go to "Profile → Notifications".
2. Activate the "Allow Notification" switch.
3. Select the apps you want to see on your watch (such as WhatsApp, Telegram, Gmail).
4. Set up the “Notification Style” – full text or just an icon.

Optimization of synchronization:

• 🔄 Enable "Autosync" in the application settings (Section "Data").
• ⏱ Set the synchronization interval: for Mi Band optimally "Every hour", for Xiaomi Watch - "Every 30 minutes".
• 📊 Turn off the backburn synchronization (saves battery power).

⚠️ Warning: If notifications don't come, check Android's power saving settings. Add Mi Fitness/Zepp Life in the list of "Battery Optimization Exceptions" (Settings) → Battery → Optimizing the battery).

Comparison of Xiaomi models on connectivity stability

Not all Xiaomi smartwatches work equally well with Android, and here is a comparison of the key parameters:

As you can see from the table, the Watch 2 Pro and Mi Band 8 show better connectivity stability, but lose out on autonomy. If you care about Bluetooth reliability, choose models with a Nordic nRF52832 chip (indicated in specs).
