The Xiaomi Smart Band 9 Pro is a premium fitness tracker featuring a 1.74-inch AMOLED screen, multi-constellation GNSS and up to 21 days of battery life, targeting outdoor enthusiasts who need accurate phone-free GPS.

Professional reviewers consider the Smart Band 9 Pro a significant step forward, emphasizing its expansive high-brightness display, robust GNSS capabilities, and comprehensive sport and health features. While the device is praised for comfort and visual clarity, the only notable drawback mentioned is the occasional lag in automatic brightness adaptation under sudden lighting changes.
Everyday users love the vivid screen, long battery life, and reliable GPS for workouts, finding the health sensors valuable. Common frustrations revolve around the band's bulk on smaller wrists, delayed auto-brightness in sunlight, and the need to replace the strap for extended comfort during long wear.
“Large 1.74-inch AMOLED screen with 336 × 480, 1200 nits is "really useful"”
“Up to 14 days of battery life in typical use, far exceeding most competitors.”
“Lacks NFC and advanced sensors such as an altimeter.”
Professional reviewers commend the Amazfit Active for its exceptional value at around $99, offering a large AMOLED screen, extensive sport modes, AI health coaching, and a standout 14-day battery. However, they point out the lack of premium sensors like an altimeter, a less refined rectangular look, and unspecified brightness that may lag behind the Active 2's 2,000-nit display.
Everyday users overwhelmingly appreciate the long battery life, feather-light weight, vivid display, and reliable fitness tracking, especially GPS and heart-rate monitoring. Recurring complaints focus on occasional Bluetooth drops, occasional GPS inaccuracies in dense areas, strap comfort for larger wrists, and the absence of NFC and broader third-party app support.
