Published on 09/18/2026 at 20:07 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
Xiaomi Smart Band 9 Pro stretches a 1.74-inch AMOLED display across a 43.27 x 32.49 x 10.8mm body and keeps the weight at about 24.5g without the strap.The global specs page also lists Bluetooth 5.4, 5ATM water resistance, and a 350mAh battery.
Display And Hardware
The display resolves to 336 x 480 pixels and reaches a maximum of 1200 nits with auto brightness adjustment.Xiaomi's spec sheet also lists GNSS support, an ambient light sensor, an optical heart rate sensor, and a pulse oximeter.
The band uses a magnetic charger and the brand says charging takes about 75 minutes.The same specification page lists a compatible wrist circumference of 135-205mm and package contents of a crown, strap, charging cable, and user manual.
Battery And Compatibility
Xiaomi says the Smart Band 9 Pro lasts up to 21 days in typical usage mode, 10 days in AOD mode, and 8 days in heavy-load mode.The product page lists Android 8.0 and iOS 12.0 as the minimum system versions and says the band works with the Mi Fitness app.
Independent coverage places the Smart Band 9 Pro in a crowded tracker field and gives a U.S. price of $79.99 for the model.That review makes the comparison point clear: this band sits above simpler fitness bands that skip GNSS and a larger AMOLED screen.
Price And Positioning
For U.S. readers, the headline number is the $79.99 MSRP, while price-comparison listings in the U.S. have shown higher offers around $94.99 and $129.10.Smartprix and Klarna show the band in the U.S. market as a mid-priced wearable rather than an entry tracker.
On Xiaomi's side, the model name itself appears in the global wearables lineup, and the U.S. support page points shoppers to Xiaomi global support for warranty terms and product questions.The U.S. support page also uses the global service address for product inquiries.
Who It Fits Best
Xiaomi Smart Band 9 Pro fits users who want a tracker with GNSS, a 1.74-inch AMOLED display, and long battery life in a compact case. The 5ATM rating and Android 8.0 or iOS 12.0 compatibility keep the feature set straightforward for daily wear and swimming pools.
