Product details
Xiaomi Smart Band 9 combines a metallic frame with a 1.62-inch AMOLED touch display. Its 192 × 490-pixel resolution presents workout records, notifications and everyday information, while automatic brightness adjustment responds to surrounding light. Peak brightness reaches up to 1,200 nits. The display supports a 60Hz refresh rate, although the rate varies across interfaces. The band measures 46.53 × 21.63 × 10.95mm excluding its strap and protrusions, and weighs 15.8g without the strap.
Choose Midnight Black, Glacier Silver, Mystic Rose or Arctic Blue with a matching TPU strap. The strap fits wrists measuring approximately 135–210mm. A quick-release design supports changing compatible straps, and optional leather, metal and other accessories are separate purchases. More than 200 watch faces are available through Mi Fitness, including supported personalised photo designs. A linear motor provides vibration feedback for reminders and interaction.
More than 150 sports modes cover different activities. Ten on-wrist running courses range from basic run-walk sessions to aerobic endurance training. An optional running clip provides additional running measurements and must be purchased separately. The sensor set includes an accelerometer, gyroscope, optical heart-rate sensor and ambient-light sensor. Heart rate, blood oxygen, sleep, stress and menstrual-cycle records provide personal wellness references. They are not designed to predict, diagnose or treat medical conditions. Selected continuous and advanced sleep functions require enabling the relevant settings in Mi Fitness or on the band.
The 233mAh battery is rated for up to 21 days of typical use, nine days with always-on display or 6.6 days under heavy use in manufacturer testing. Actual duration depends on settings, activity and surroundings. Magnetic charging takes approximately one hour. Mi Fitness supports Android 8.0 or iOS 12.0 and later phones; some reminders require the app to run in the background. The 5ATM rating supports suitable pool and shallow-water activities, but excludes hot showers, saunas, diving and swift currents. Water resistance can decline with use. The package includes the band with its standard strap, magnetic charging cable and user manual.
