Xiaomi Smart Band 9

Xiaomi Smart Band 9 is the best value fitness tracker in the game, and the 9th generation makes a strong case for why.

For the first time, the Smart Band comes in a colorful aluminum alloy frame — Midnight Black, Glacier Silver, Mystic Rose, Arctic Blue, and Titan Gray — giving it a premium look that punches well above its price point. The 1.62-inch AMOLED display hits 1,200 nits peak brightness, making it easy to read in direct sunlight, with auto-brightness adjusting to any environment.

Heart rate accuracy is up 16% over the Band 8, and SpO2 monitoring gets an equivalent upgrade — both running continuously day and night. Sleep tracking covers all stages with improved precision, and 150+ sport modes include 10 dedicated running courses, VO2 max tracking, and recovery time estimates.

The watch-grade linear motor delivers 20 unique vibration modes for notifications and alerts. Pair it with a running clip accessory (sold separately) to track 13 advanced running metrics including cadence, stride length, and ground contact time.
