The seventh major model of Xiaomi's affordable fitness tracker series is the Xiaomi Mi Band 7. It was initially launched in China and officially became available on May 31. Xiaomi later announced its plans for a global rollout, referring to the device as the Mi Smart Band 7 in international markets.
As usual, Xiaomi doesn’t just sell one Mi Band model in all countries but has different options for its home market and the rest of the world. Kicking off the offering is the standard version, priced at 249 Chinese yuan ($37). The NFC version follows at 299 yuan ($44). In Europe, the Mi Band 7 starts at €59.99 ($63). Those in the US can purchase one for ~$50.

The Mi Band 7 enhances several features found in the Mi Band 6. It boasts an enlarged battery, a larger screen, and an expanded range of sport tracking modes. Moreover, it introduces new functionalities tailored for dedicated fitness enthusiasts, including continuous SpO2 monitoring with alerts. Additionally, the Mi Band 7 comes in a variety of vibrant colors, such as Ivory, Orange, Green, Blue, Black, Pink, Fluorescence Green, Fluorescence Orange, Camouflage Green, and Camouflage Blue.

HARDWARE DESIGN
The Xiaomi Mi Band 7 uses a 1.62-inch AMOLED screen with a 490 x 192 resolution. Compared to the Mi Band 6’s 1.56-inch AMOLED with 486 x 152 resolution panel, that’s a noticeable size up. With this larger display, Xiaomi’s also improved the UI, bringing in new icons, animations, and a revised visual aesthetic that should make peeking at data easier.
With the larger screen comes a greater demand for power. To compensate, Xiaomi’s upped the battery capacity in the Mi Band 7 to 180mAh. That’s a 44% increase over the Mi Band 6. Of course, the larger capacity doesn’t immediately guarantee the Mi Band 7 will last longer between charges. As we experienced with its predecessor, smart features do a good job draining the battery. We expect continuous SpO2 tracking to be one of the main power hogs.

The Chinese Mi Band 7 model features NFC with Xiaomi’s voice assistant. It also supports contactless payments. It’s unclear if global models will also receive NFC or the return of Amazon Alexa to the wrist. This would be a welcome addition, though.

Health and Fitness Tracking features
In addition to its existing features, the Mi Band 7 introduces advanced capabilities such as monitoring training load, recovery duration, and training effect. These factors provide valuable context to understand the impact of exercise on the body, offering a more comprehensive assessment than just tracking calories burned. Furthermore, the Mi Band 7 incorporates VO2 max monitoring, which allows users to track their maximum oxygen intake during workouts. Another noteworthy addition is continuous SpO2 monitoring, enabling users to monitor their blood oxygen saturation levels. In the event that this value drops below 90%, the Mi Band 7 will promptly alert the user.
Beyond these new features, all the basic fitness tracking smarts make a return. Heart rate monitoring, daily steps, distance, caloric burn, and sleep tracking are all included. Stress tracking and women’s health monitoring round out the offering.
