In the world of smart bracelets, Xiaomi stands out with Smart Band 7 and Smart Band 8. Designed to meet the needs of the modern user, both devices have different features.

From changes in size and design to improvements in battery and tracking capabilities, these two models are committed to comfort and functionality. Next, we will examine the differences and new features offered by each of these devices.

Smart Band 8, on the other hand, offers a strap ranging from 13.5 cm to 21 cm, also made of TPU. But the latter offers a novelty: easy-to-remove straps available in new frame colors such as Champagne Gold and Graphite Black.


The display is another feature that has undergone change. Both wristbands have a 1.62-inch AMOLED touchscreen with a resolution of 192 x 490 pixels.

Protected by tempered glass with anti-fingerprint coating, Smart Band 7 offers up to 500 nits of brightness and its viewable area is 25 percent larger than its predecessor, Smart Band 6.

Battery is another point where the Smart Band 8 slightly outperforms the 7. While the second one takes less than 2 hours to charge, it lasts at least 14 days and has a capacity of 180 mAh, The latest model charges in about 1 hour, can last up to 16 days and has a capacity of 190 mAh.

In terms of fitness features, the Smart Band 7 offers more than 110 modes and five auto-sensing modes (outdoor running, walking, treadmill, rowing machine, elliptical). Smart Band 8 expands its offering to more than 150 modes, adapting even better to user preferences.

Both bands offer similar functionality in terms of health monitoring, but only the Smart Band 7 highlights SpO₂ tracking and some features in sleep tracking.

Smart Brand 7 features heart rate monitoring, SpO₂ monitoring, sleep monitoring (deep sleep, light sleep, REM and naps), sleep breathing quality monitoring, women’s health monitoring, and stress monitoring.

Smart Brand 8 stands out with its scientific sleep monitoring, day-long stress and heart rate monitoring and women’s health management features.

Finally, regarding their technical features, both bracelets are water-resistant with 5 ATM resistance and use the Mi Fitness application. Smart Band 7 uses Bluetooth 5.2 BLE and is compatible with Android 6.0 and iOS 10 onwards. Smart Band 8 uses Bluetooth 5.1 BLE, compatible with Android 6.0 or iOS 12.0 and newer.

In this case, Smart Band 8 can be worn both on the wrist and around the neck as a necklace, or with a special strap attached to shoelaces. This allows you to retrace your steps more carefully without having to show the bracelet all the time.
