Score: 79/100Rankings
The Xiaomi Mi Smart Band 10 (2025) Global Version is a budget-friendly fitness tracker featuring a 1.72-inch AMOLED screen, 21-day battery life and comprehensive sport tracking including accurate swim metrics. Its main limitations are the lack of standalone GPS and a less robust band clasp. It is best for cost-conscious users who want long endurance and a bright display for everyday activity monitoring.
The Polar H7 is a chest-strap heart-rate sensor delivering ECG-grade accuracy and a long-lasting CR2025 battery. It lacks ANT+ support and cannot transmit data while swimming, and its older design may feel bulkier. Best suited for athletes who need precise chest-based heart-rate data and long battery life.

Professional reviewers commend the H7 for its ECG-grade accuracy, long-lasting battery, and lightweight belt design, noting its seamless Bluetooth and GymLink integration for a wide range of devices. However, they point out its legacy status, lack of ANT+ and inability to transmit data underwater, making it less future-proof than newer Polar models.
Everyday users appreciate the H7's reliable Bluetooth pairing, comfortable elastic strap, and long battery life, especially for running, gym, and swimming workouts. Recurring complaints focus on occasional pairing hiccups with non-Polar phones, strap stretch over time, and the desire for a lighter, wrist-based alternative.
Professional reviewers commend the Smart Band 10 for its sizable, ultra-bright AMOLED screen, impressive 21-day battery, and highly accurate heart-rate and swim tracking. The addition of an electronic compass and a linear-motor haptic system are seen as meaningful upgrades that elevate the device above its predecessor, while the extensive sport mode library adds versatility. Criticisms focus on the lack of built-in GPS, occasional clasp durability issues, and the hit-or-miss nature of auto-detect workouts, as well as the absence of medical-grade sensors.
Everyday users consistently praise the band's long battery life, bright display, and reliable step, heart-rate, and sleep tracking. Swimmers especially value the 96 % lap-count accuracy and underwater HR broadcast. Common complaints revolve around the missing GPS, unreliable band clasp, and limited smart-phone-only notifications, with many noting that auto-detect workouts can be erratic.
“1.72-inch AMOLED display with 1500 nits peak brightness provides excellent outdoor visibility.”
“No built-in GPS requires a connected phone for location tracking during outdoor activities.”
