Most fitness trackers at this price use basic LCD displays. The Smart Band 9 brings a vivid AMOLED always-on screen — rare at this price point.
Continuous heart rate, SpO2, stress, and sleep tracking — all running for 2 weeks before charging. Most smartwatches last 1–2 days.
Full functionality on both platforms via the Mi Fitness app, including notifications, sleep analysis, and health trends.
18 days of typical use with health monitoring — nearly 3 weeks without charging, far beyond any smartwatch competitor.
Ask Alexa for weather, timers, reminders, and smart home controls directly from your wrist — unusual for a sub-$50 fitness band.
