Xiaomi Smart Band 9 Pro and Xiaomi Watch S4 Unveiled

Xiaomi introduced the Smart Band 9 a few months ago, and now it’s followed up with the Smart Band 9 Pro. Just like other Pro versions in Xiaomi’s popular fitness band series, this model has a bigger, square screen. The Smart Band 9 Pro sports a 1.74-inch AMOLED display, offering crisp visuals at a 336×480 resolution and peaking at an impressive 1,200 nits of brightness. The device itself measures 43.27 x 32.49 x 10.8 mm and weighs 24.5 grams, keeping it lightweight, thanks to its durable aluminum alloy frame. The new wearables join the big stars of the show the Xiaomi 15 and Xiaomi 15 Pro.
