Each of these devices offers a unique blend of sensors and features. Keep reading as we embark on this side-by-side comparison.
The Redmi Watch 4 offers a classic, durable design, while the Mi Smart Band 8 Pro embraces a sleek, modern look. Both devices provide essential health and fitness tracking with various sensors and built-in GPS. Your decision boils down to style preferences and whether you prioritize fitness tracking or a traditional watch-like appearance, all at competitive prices for budget-conscious users.
Redmi Watch 4 vs Xiaomi Mi Smart Band 8 Pro: Hardware
Look & feel
One of these is officially a fitness band, the other a smartwatch. But you wouldn’t be able to tell that by looking at them. Both have a smartwatch-like appearance. What’s obvious, though, is that Redmi Watch 4 has a square-shaped design, while the Xiaomi opts for a more elongated look.
The build quality of both devices reflects the company’s commitment to durability and style. The Redmi Watch 4 features a plastic back and an aluminium frame with a stainless steel finish. In contrast, the Mi Smart Band 8 Pro opts for a high-strength fibre polymer case with a TPU wristband, lending it a sleeker, more modern look.
Size-wise, the Redmi Watch 4 is slightly larger, measuring 47.6 x 41.1 x 10.5 mm, compared to the Mi Smart Band 8 Pro’s dimensions of 46 x 33.35 x 9.99 mm. This difference in size may influence user preference based on wrist size and comfort.
Physical buttons are another aspect where these two devices diverge. The Redmi Watch 4 includes a single rotating crown, which not only adds to its classic watch aesthetic but also provides a tactile and intuitive way to navigate the device’s interface. The Mi Smart Band 8 Pro, on the other hand, does away with physical buttons entirely. It relies solely on its touchscreen for navigation. This choice enhances the band’s minimalist design but may affect ease of use during activities like sports or workouts.
Display, colour options, water resistance
The screen is a standout feature for both models. The Redmi Watch 4 boasts a 1.97-inch AMOLED display with a resolution of 450 x 390 pixels, offering vibrant colors and sharp visuals. The Mi Smart Band 8 Pro, while slightly smaller at 1.74 inches, also features an AMOLED display, but with a resolution of 336 x 448 pixels. Both screens are designed to provide clear visibility in various lighting conditions, with the Redmi Watch 4 reaching a peak brightness of 600 nits.
Water resistance is a key feature for any wearable device, and both models excel in this area with a 5 ATM rating. This means they can withstand pressures equivalent to a depth of 50 meters, making them suitable for activities like swimming or showering.
Color options allow users to personalize their devices to their taste. The Redmi Watch 4 is available in Black and White, offering a classic and versatile look. The Mi Smart Band 8 Pro comes in Black and Grey, colors that are equally adaptable to different styles and preferences.
As far as sensors, the Redmi Watch 4 is equipped with an accelerometer, a 4-channel PPG sensor for heart rate monitoring, a compass, a gyro, and an SpO2 sensor for blood oxygen level measurement. This comprehensive array allows for a wide range of health and fitness tracking capabilities. In contrast, the Mi Smart Band 8 Pro includes a 6-axis sensor, which combines a low power-consumption 3-axis accelerometer and a 3-axis gyroscope, along with a PPG heart rate sensor, SpO2 sensor, and an ambient light sensor. The 6-axis sensor in the Mi Band 8 Pro enhances motion tracking accuracy, making it slightly more adept in fitness and movement tracking. But there’s not a huge difference there.
For GPS connectivity, both devices offer robust location tracking features. The Redmi Watch 4 supports multiple global navigation satellite systems, including GPS, GLONASS, Galileo, BDS, and QZSS, ensuring precise location tracking across various regions. The Mi Smart Band 8 Pro also offers comprehensive GPS connectivity with support for GPS, Galileo, Glonass, and QZSS.
When it comes to NFC (Near Field Communication), both devices offer this feature, but with regional variations. The Redmi Watch 4’s NFC availability is market or region-dependent, while the Mi Smart Band 8 Pro offers NFC exclusively in China. This means the utility of NFC for contactless payments and other functionalities will vary depending on the user’s location.
Regarding music storage, neither the Redmi Watch 4 nor the Mi Smart Band 8 Pro offers onboard music storage. This absence means users will rely on their connected smartphones to play music, which might be a limitation for those looking to use these devices independently during workouts or outdoor activities.
Both of these devices showcase advancements in battery technology, ensuring users can enjoy their features without frequent recharging.
The Redmi Watch 4, powered by a 420 mAh battery, promises about 20 days of usage under normal conditions, and approximately 7 days with more intensive use, including the always-on display feature. This longevity is particularly noteworthy given the device’s large 1.97-inch AMOLED display, which typically consumes more power.
On the other hand, the Mi Smart Band 8 Pro, with its 289mAh battery, offers up to 14 days of battery life on a single charge and around 6 days with the always-on display activated. Despite its slightly smaller 1.74 inch AMOLED screen, the Mi Band 8 Pro balances display quality and energy efficiency effectively.
