  2. Confirm the reset.
  3. Repeat the connection process from scratch.

⚠️ Attention: On some models Xiaomi Watch a factory reset also deletes all physical activity data stored locally on the device. If this information is important to you, synchronize the data with the application before resetting.

6. Additional settings after connection

When the watch is successfully paired with the phone, you can configure additional functions for maximum convenience.

Customizing screens and dials

In the application Mi Fitness or Zepp Life go to section Display → Watch faces. Here you can:

  • 🎨 Install one of the preloaded watch faces.
  • 📥 Download new watch faces from the official store (more than 100 options available).
  • ⚙️ Customize the displayed information (date, weather, steps, pulse, etc.).

Activation of health functions

For full health monitoring, enable in the watch settings:

  • 🩺 Pulse measurement (automatic or scheduled).
  • 😴 Sleep tracking (deep/light sleep, awakenings).
  • 💦 Stress level (available on models with a sensor PPG).
  • 🩺 Blood oxygen level (SpO₂) (on Xiaomi Watch 2 Pro and newer).

Setting up alerts and alarms

In section Notifications you can:

  • ⏰ Create smart alarm clocks (with a smooth increase in vibration).
  • 🔔 Adjust sedentary reminders (if you sit for too long).
  • 📵 Enable Do not disturb mode for a certain time.

On models with NFC (for example, Xiaomi Watch S3) you can also set up contactless payment via Mi Pay. To do this, you will need to link a bank card in the application and activate the function on the watch.

💡

After the first connection, be sure to update the firmware of the watch through the official application - this will fix possible bugs and add new functions.

7. Optimizing watch operation to save battery

One ​​of the most common complaints from users is quick battery drain on smart watches Xiaomi. Fortunately, there are several ways to extend the operating time:

  • 🔋 Disable automatic heart rate measurement (leave only manual mode).
  • 🌙 Reduce screen brightness or enable automatic adjustment.
  • 📶 Disable the constant connection to Bluetooth (in the watch settings, set the synchronization interval once every 1-2 hours).
  • 🔔 Limit the number of notifications (leave only the most important ones).
  • 🌡️ Disable the SpO₂ sensor, if you do not use it regularly.

On models with AMOLED screen (for example, Xiaomi Watch 2 Pro) the use of dark dials also helps - they consume less energy. In the screen settings, you can enable the mode Always-On Display (always active screen), but this will significantly reduce the operating time.

If even after optimization the battery runs out too quickly (in less than a day), check:

  • Is there a background application (for example, a music player) running on the watch?
  • Is the mode turned on GPS (if so, turn it off in the location settings).
