The Smart Band 9 (M2345B1, BHR8346GL) promises a lot: a vibrant 1.62-inch AMOLED display, comprehensive health tracking features, and a battery life that lasts for weeks. But does it deliver on these promises? I’ve been wearing the Arctic Blue version for the past few weeks, putting it through its paces with various workouts and daily activities, to bring you this thorough review.

The Smart Band 9 is packed with features. Beyond its stunning AMOLED display with a crisp 192×490 resolution and adjustable brightness (up to 1200 nits!), it boasts a full suite of health and fitness tracking capabilities. This includes accurate heart rate and SpO2 monitoring, sleep tracking, and a variety of workout modes. The sleek aluminum alloy middle frame and durable 2.5D tempered glass give it a premium feel, while the comfortable silicone band ensures all-day wearability.

The intuitive touchscreen navigation is responsive and easy to use, even during workouts. Connecting to the Xiaomi Sports Health app is straightforward, providing detailed analysis of your fitness data. The app also allows for customization of watch faces and notifications.

In terms of performance, the Smart Band 9 exceeded my expectations. The heart rate and SpO2 readings were consistent with other devices I’ve tested. Sleep tracking data was detailed and insightful, providing valuable information about my sleep patterns. The battery life is a standout feature; I easily got over 20 days on a single charge, even with regular use and notifications enabled. The accuracy of the GPS during outdoor runs was surprisingly good for a device of this size and price.

However, there are a few minor drawbacks. While the display is bright and vibrant, it can be difficult to read under direct sunlight. The notification system, while functional, could be improved with more customization options. The accuracy of blood pressure readings is acceptable for a fitness tracker but not a medical device.

Pros:

• Stunning 1.62-inch AMOLED display
• Long battery life (over 20 days)
• Accurate heart rate and SpO2 monitoring
• Comfortable and durable design
• Detailed sleep tracking
• Good value for the price

Cons:

• Display can be difficult to read in direct sunlight
• Limited notification customization options
• Blood pressure readings may be less accurate than dedicated medical equipment

Overall, the Smart Band 9 (M2345B1, BHR8346GL) is an excellent fitness tracker. Its vibrant display, impressive battery life, and comprehensive health tracking capabilities make it a strong contender in its price range. While it has a few minor shortcomings, they are easily overshadowed by its numerous strengths. If you’re looking for a stylish and functional fitness tracker without breaking the bank, the Smart Band 9 is a highly recommended choice.
