The Xiaomi Mi Band 7 Activity Tracker is a feature-packed device that offers a high-resolution 1.62" AMOLED screen, Bluetooth 5.2, and over 120 sports modes. It also includes an optical heart rate and blood oxygen sensor, making it a versatile tool for fitness enthusiasts.

One of the standout features is its compatibility with both the Mi Fitness and Zepp Life apps. The Zepp Life app, in particular, offers additional functionalities such as message replies and remote camera control, enhancing the user experience.

Health tracking is robust, with over 100 workout modes and continuous monitoring of heart rate and calories. However, note that continuous heart monitoring is only available during workout modes. The watch also calculates VO2 Max and workout load, providing insights into your fitness progress.

Battery life is impressive, lasting up to 7-8 days with moderate use. A battery saver mode can extend this to around 14 days. Daily charging for about 20 minutes keeps the battery in the optimal range.

Other notable features include customizable watch faces, smart alarms, media control during workouts, and a find my phone function. However, the lack of a light sensor means manual brightness adjustment is necessary.

Overall, the Xiaomi Mi Band 7 offers excellent value for its price point, making it a strong contender in the smartwatch market.
