Rare combination: a bright always-on AMOLED display and 14 days of typical use without charging.
Medical-grade ECG and bioelectrical impedance body fat analysis — features usually found only on watches costing $100–$200 more.
Zepp Coach uses Amazfit's AI to build personalised workout plans, recovery recommendations, and stress management guidance.
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.
