Xiaomi's New Fitness Tracker Balances Screen Size and Battery Life

Xiaomi has released the Smart Band 9 Pro, a fitness tracker that prioritizes a larger screen and extended battery life over extreme thinness. The device features a 1.74-inch AMOLED display that is significantly bigger than standard entry-level bands, allowing for more detailed health metrics and notifications. According to reports from GN auto tech/wearables: fitness tracker, the band is positioned as a mid-range wearable that bridges the gap between simple activity trackers and smartwatches.

The primary selling point is the battery performance, which claims up to 21 days of usage in typical modes. This longevity is achieved through a 350mAh battery, which is larger than many competitors but comes with a trade-off: the device is thicker than standard bands. At 10.8mm thick and weighing approximately 24.5 grams without the strap, it is a solid but not ultra-light option for users who prioritize screen real estate and battery endurance above all else.

Display Quality and Sensor Suite

The 1.74-inch display offers a resolution of 336 by 480 pixels, providing a clear and bright viewing experience even in direct sunlight with a peak brightness of 1,200 nits. Under the hood, the tracker includes a comprehensive set of sensors, including an optical heart rate monitor, a pulse oximeter for blood oxygen levels, and an ambient light sensor for automatic brightness adjustment. These components work together to provide detailed health insights without requiring a smartphone for basic tracking.

Notably, the device supports GNSS, which allows it to track running and cycling routes independently without needing a paired phone. This is a significant upgrade over cheaper bands that lack satellite navigation. The combination of a large, bright screen and independent GPS makes the device suitable for outdoor activities, though the bulkier form factor may feel less discreet on the wrist compared to slimmer models.

Durability and Water Resistance

The Smart Band 9 Pro is rated for 5ATM water resistance, making it suitable for swimming in pools and shallow water activities. This level of durability ensures the device can handle daily wear and tear, including accidental exposure to water during hand washing or rain. The magnetic charging system is standard for this category, taking approximately 75 minutes to reach a full charge. While the charging time is average, the long battery life means users will only need to charge the device about once every two to three weeks.

The band is compatible with a wide range of devices, requiring Android 8.0 or iOS 12.0 as minimum system versions. This broad compatibility ensures that most smartphone users can pair the device without issue. The package includes a strap, a charging cable, and a user manual, providing a straightforward setup process. The physical design includes a crown-like button for navigation, adding a tactile element to the touch-screen interface.

Pricing and Market Position

In the U.S. market, the Smart Band 9 Pro is priced at $79.99, positioning it as a mid-tier wearable. This price point is higher than entry-level bands, which often lack features like GNSS and larger displays, but lower than premium smartwatches. Some retailers have listed the device at higher prices, ranging from $94.99 to $129.10, so shoppers should compare options to ensure they are getting the manufacturer's suggested retail price.

For consumers, the decision to choose this band depends on their priorities. If a large, bright screen and independent GPS tracking are essential, the Smart Band 9 Pro offers strong value. However, users who prefer a lighter, thinner device or are looking for the lowest possible price may find simpler, less feature-rich alternatives more suitable. The trade-off is clear: you gain screen size and battery life at the cost of increased thickness and a slightly higher price tag.
