Xiaomi Smart Band 9 Pro gets 21 day battery life & brighter display
Xiaomi has unveiled its latest fitness tracker, the Smart Band 9 Pro, at an event in China. There is little that is new beyond extended battery life and a brighter display.
For starters, the Smart Band 9 Pro maintains the familiar 1.74-inch AMOLED display of its predecessor, with a 60Hz refresh rate. But it now offers double the peak brightness at 1200 nits, making it considerably easier to read outdoors. The aluminum case comes in three color options – black, gold, and pink – and maintains a slim profile weighing a mere 24.5 grams. The dimensions of the device have changed by a fraction.
Battery life sees a significant boost in this iteration, with Xiaomi claiming up to 21 days of usage on a single charge. That’s up by a week on Band 8 Pro. Expect that to come down rapidly, though, with always-on display and GPS switched on.
Beyond that you get the same comprehensive fitness tracking capabilities with over 150 sports modes and built-in satellite functionality. Xiaomi has also reportedly enhanced the accuracy of both sleep tracking and heart rate monitoring. NFC for contactless payments, also appears, but most likely only for the Chinese iteration.

For context, the previous model, the Xiaomi Band 8 Pro, has been well-received in various markets, particularly in Europe, where it sells for around 65 euros. In my hands-on review, I found it offered exceptional value with its built-in GPS, large display, and comprehensive fitness tracking features. However, the lack of NFC and occasional GPS inconsistencies in urban areas are some limitations. Hopefully, this iteration improves those areas.
The Smart Band 9 Pro launches with flexible band options, including both sporty and leather variants, with a Milanese loop available separately. The device maintains 5ATM water resistance.
Currently, the Smart Band 9 Pro is available exclusively in China, with pricing starting at 399 yuan (around €50) for the sports band version and 449 yuan (around €60) for the leather variant. Global availability details remain pending.
