The Xiaomi Smart Band 9 went official a few months back, and today it's received a sibling: the Smart Band 9 Pro. Like previous Pro versions in Xiaomi's best-selling line of wearables, this one has a larger, squarer screen compared to the non-Pro Smart Bands. The Smart Band 9 Pro's display is 1.74" in diameter, AMOLED of course, with 336x480 resolution and 1,200-nit peak brightness. The entire wearable measures 43.27 x 32.49 x 10.8 mm and weighs 24.5g thanks to its aluminum alloy body.
It's 5ATM water resistant, and has a 350
mAh battery that's rated for up to 21 days of use. It has NFC on board, along
with Bluetooth 5.4 and GPS, GLONASS, Galileo, and QZSS support. It's compatible
with smartphones running Android 8 and later, as well as iPhones running iOS 12
and later. Like any device of its type, the Smart Band 9 Pro measures your
heart rate, blood oxygen level, stress, and analyses your sleep too. There are
over 150 sports modes to choose from, including enhanced tracking for running
and swimming.
The Smart Band 9 Pro starts at CNY 399
(US$ 56), while magnetic quick release straps are priced at CNY 169 (US$ 23) and
leather quick release straps at CNY 99 (US$ 13). The Watch S4 has a 1.43-inch
AMOLED display with 466x466 resolution and 2,200-nit peak brightness, and a
user-swappable bezel. It has 5ATM water resistance too, as well as over 150
sport modes.
The watch comes in two versions, one of
them with eSIM support. It measures 47.3 x 47.3 x 12 mm and weighs 44.5g. It
has Bluetooth 5.3 and supports the same satellite positioning systems and phone
operating systems as the Smart Band 9 Pro. Like that product, it also monitors
your heart rate, blood oxygen level, and stress. The watch additionally has
built-in running training courses and AI-driven route planning (whatever that
means). The dual-mode walkie-talkie function and eSIM support allow for
listening to music and making calls without a phone.
You can reply to messages, send emojis,
and control Xiaomi smart home devices directly from the watch. In China, you
can also use it as an NFC car key. The Watch S4 starts at CNY 999 (US$ 140). This
launch event was for the Chinese market only, so we don't yet know when these
devices will make it to international markets, but we'll let you know as soon
as we find out.
