Xiaomi Band 9 Pro is the most exquisite smart band with the narrowest frame so far. Compared with the first generation of Xiaomi Mi Band, you will feel that it is more like a square smart watch. The word "band" is really a bit condescending to its identity.
Performance:
Xiaomi Band 9 Pro is equipped with the new Xiaomi HyperOS 2 system. For the first time, it supports focus notifications, takeout travel information, and mobile takeout taxis. The band can be synchronized in time, can be seamlessly connected with the Apple Health App, share sports health data, and support synchronization reminders of phone calls and WhatsApp messages.
Xiaomi Mi Band 9 Pro supports all-day heart rate monitoring, all-day blood oxygen monitoring, women's health management, all-day stress monitoring, breathing training, upgraded high-precision sensors, and with the new self-developed heart rate algorithm, the heart rate monitoring accuracy reaches 98%, achieving more accurate health and exercise monitoring, providing you with multi-dimensional health data and all-weather protection.
In terms of monitoring, the sensor is upgraded with the algorithm, and the accuracy of sleep monitoring is improved by 4.4% and the accuracy of heart rate monitoring is improved by 15%. Xiaomi Band 9 Pro has in-depth cooperation with professional medical institutions for sleep analysis, supporting sleep risk health research, sleep stage monitoring and sleep rhythm monitoring.
In addition, this bracelet product also launched the NFC car key function, which can be unlocked by swiping the card close to the Xiaomi car sensing area, and supports smart card cutting by raising the wrist, so the wearer does not need to manually switch to use the community access card, bus card or open the MIJIA smart door lock.
It supports independent GNSS positioning, with upgraded high-precision GNSS chip, and has a new antenna design and self-developed algorithm support. The positioning accuracy is 33% higher than the previous generation, and the trajectory is more accurate. It supports both joint use with mobile phones and independent use.
Finally, Xiaomi Band 9 Pro has also made significant improvements in battery life. Thanks to the application of a larger 350mAh battery and a new low-power chip, the bracelet has a battery life of more than 21 days in typical mode, up to 10 days in AOD mode, and 8 days in heavy load mode.
Appearance:
Xiaomi Band 9 Pro continues the 1.47-inch screen, and has made significant upgrades in design based on the previous generation. Through the 2.5D curved screen and 2.2mm four-sided narrow frame design, the screen-to-body ratio of the bracelet is increased to 77%, bringing a wider field of view.
The new screen uses upgraded luminous materials with a brightness of up to 1200 nits, which is twice that of the previous generation. It can display clearly no matter what environment it is in. In addition, this screen supports a 60Hz refresh rate and 480×336 resolution, which makes the operation smoother and brings users a better visual experience.
Xiaomi Band 9 Pro adopts a colorful aluminum alloy middle frame design, combined with a sandblasting matte process, presenting a low-key and exquisite texture. This material and process not only gives the bracelet an elegant appearance, but also brings the characteristics of being difficult to get fingerprints, keeping the device clean and beautiful.
