For the past few weeks, I’ve been wearing the Smart Band 9 (M2345B1, BHR8345GL), a fitness tracker boasting a vibrant 1.62-inch AMOLED display. This in-depth review delves into its capabilities, from daily activity tracking to sleep monitoring and beyond. I’ll share my honest experiences, highlighting both its strengths and weaknesses, to help you decide if it’s the right fit for your needs.

The Smart Band 9 packs a surprising number of features into its compact design. The standout is undoubtedly the AMOLED display – bright, crisp, and easily readable even in direct sunlight. The touchscreen responsiveness is excellent, making navigation intuitive and smooth. Beyond the screen, it includes a comprehensive suite of health and fitness tracking capabilities. This includes heart rate monitoring, blood oxygen (SpO2) measurement, sleep tracking, and a surprising array of sports modes catering to various fitness levels and preferences.

I particularly appreciated the accuracy of the heart rate monitor, which consistently matched my readings from other devices. The sleep tracking offered detailed insights into my sleep patterns, including deep sleep, light sleep, and REM cycles. The app integration with Xiaomi Sports Health is seamless, providing a centralized platform to view all your fitness data.

In terms of performance, the Smart Band 9 consistently exceeded my expectations. The battery life, advertised as up to 21 days, held up remarkably well during my testing. Even with heavy usage, including continuous heart rate monitoring and multiple workout sessions, I easily managed to get over a week on a single charge. This is a significant plus point, eliminating the constant worry of low battery.

The accuracy of the fitness tracking is impressive. I tested it during various workouts, including running, cycling, and strength training, and found it to be quite precise. The data synced flawlessly to the Xiaomi Sports Health app, allowing for easy monitoring of progress. While the GPS tracking is absent, it’s a feature commonly omitted at this price point.

The notification system also functioned well, providing timely alerts for calls, messages, and app notifications.

Pros

The Smart Band 9 (M2345B1, BHR8345GL) is a fantastic fitness tracker offering a compelling combination of features, performance, and style. The vibrant AMOLED display and long battery life are definite highlights. While the lack of built-in GPS might be a deal-breaker for some serious athletes, for most users, it provides a comprehensive and accurate tracking experience at an attractive price point. I highly recommend it.
