Xiaomi Smart Band 9 Active – Fitness Tracker, 18-Day Battery

You shouldn't have to think about your fitness tracker. It should just be there - on your wrist, doing the work, staying out of the way. At 16.5g, the Xiaomi Smart Band 9 Active is barely-there by design, light enough to forget you're wearing it but smart enough to track everything that matters.

The 1.47-inch TFT display runs at 60Hz, making every swipe feel smooth and responsive - no lag, no stuttering. Choose from over 100 watch faces to match your mood, your outfit, or your workout. The replaceable frame means your band can keep up with your style, not just your steps.

Where it really earns its place is under the surface. PPG sensors and light path detection work together to track your heart rate, SpO₂ levels, and stress in real time. Scientific sleep monitoring captures deep sleep, light sleep, and REM stages so you can actually understand your rest, not just log it. Women's health management is built in too, this band is designed for everyone.

With 50 sports modes covering everything from running and cycling to rowing, you get real-time metrics for whatever you're doing. And with 5ATM water resistance, it comes with you to the pool, the rain, and everywhere in between.

One charge lasts up to 18 days. When it is time to plug in, magnetic charging has it ready in under two hours. Works with Mi Fitness on both Android 8.0 and iOS 12.0 and above.
