Samsung Galaxy Fit3 vs Xiaomi Mi Smart Band 8: Hardware

Look & feel

The Galaxy Fit3 adopts a rectangular shape, a common design choice for fitness bands, and is constructed with an aluminum case, lending it a premium feel. Its dimensions are 42.9 x 28.8 x 9.9mm, making it a moderately sized device on the wrist. You could say it blends the appearance of a smartwatch with a fitness band. Which may not be to everyone’s liking.

The Mi Smart Band 8 also features a curved, rectangular shape but opts for a high-strength fibre polymer build with a TPU wristband. This might feel more lightweight and less premium compared to the Fit3’s aluminum construction. The Mi Smart Band 8 is slightly taller but much narrower, measuring 48mm × 22.5mm × 10.99mm. So it offers a less substantial presence on the wrist.

The Samsung Galaxy Fit3, designed exclusively for wrist wear, adheres to the traditional approach of fitness trackers. In contrast, the Xiaomi Mi Smart Band 8 introduces versatility in wearability with its innovative two-piece detachable band and new strap connection. This design allows users not only to wear it on the wrist but also as a necklace or attached to shoes, offering flexibility for different activities and personal preferences.

Regarding physical buttons, the Galaxy Fit3 includes one physical button on the side, which aligns with its minimalist design approach. The Mi Smart Band 8, however, goes for a sleeker look with no physical buttons, relying entirely on touch-screen interactions. This difference in button design could influence the user experience, with some preferring the tactile feedback of a physical button and others enjoying the seamless look of a button-less design.

Display, colour options, water resistance

The screens of both devices are AMOLED. The Galaxy Fit3 features a 1.6-inch display, while the Mi Smart Band 8 has a slightly larger (but narrower) 1.62-inch screen. This similarity in screen technology and resolution means both devices offer crisp and clear displays.

Water resistance is a key feature for fitness wearables, and both devices excel in this area. Each offers a water resistance rating of 5 ATM, indicating they can withstand pressures equivalent to a depth of 50 meters.

Color options for the devices allow for personalization and style preferences. The Galaxy Fit3 is available in Prism Crush White, Pink, and Dark Gray, offering a range of classic and playful colors. The Mi Smart Band 8, on the other hand, is available in Black and Light Gold, catering to those who prefer more traditional or elegant color schemes.

Sensor technology

The Galaxy Fit3 is equipped with an accelerometer, gyroscope, heart rate monitor, SpO2 sensor for blood oxygen monitoring, a barometer, and an ambient light sensor. This is quite a comprehensive suite of sensors.

On the other hand, the Xiaomi Mi Smart Band 8 includes a 6-axis sensor, which consists of a low power-consumption 3-axis accelerometer and a 3-axis gyroscope, along with a PPG heart rate sensor and an SpO2 sensor. While it shares some similarities with the Fit3 in terms of basic sensor capabilities, it lacks the barometer found in the Fit3.

When it comes to GPS connectivity, both devices rely on connected GPS. This means they do not have built-in GPS modules and require a paired smartphone to access GPS data. This approach is common in fitness trackers to conserve the device’s battery life and reduce size and cost. However, it does mean that users will need to carry their smartphones with them to track GPS-based activities accurately.

NFC (Near Field Communication) capabilities also differ between the two devices. The Galaxy Fit3 does not offer NFC support, limiting some functionalities like contactless payments. In contrast, the Xiaomi Mi Smart Band 8 includes NFC, but it’s important to note that this feature is only available in the China version of the device.

Regarding music storage, neither the Samsung Galaxy Fit3 nor the Xiaomi Mi Smart Band 8 provides the option to store music directly on the devices. This means users cannot use these fitness bands as standalone music players and will need to rely on their smartphones or other devices for music playback during workouts or leisure activities.

Battery life

The battery life of the Samsung Galaxy Fit3 and Xiaomi Mi Smart Band 8 highlights their efficiency and user convenience. The Galaxy Fit3, equipped with a 208 mAh Li-po battery, offers up to 13 days of usage on a typical charge. This is a particularly notable achievement given its large AMOLED display. Samsung has optimized the device for fast charging, achieving 65% battery in just 30 minutes.

The Xiaomi Mi Smart Band 8 packs a slightly smaller 190 mAh battery. However it surpasses the Fit3 in terms of longevity. The device delivers up to 16 days of usage under typical conditions and can last for 6 days even with an always-on display. Plus, it only takes an hour to charge the Mi Smart Band 8 from zero to full.
