Xiaomi Mi Band 2 Fitness Tracker with OLED Screen, Heart Rate Monitor and 20-Day Battery

The Xiaomi Mi Band 2 combines core fitness tracking with smartphone connectivity in a lightweight, waterproof design. Its primary function is monitoring your heart rate via an optical sensor and counting steps using efficient acceleration sensors, all displayed on a clear 0.42-inch OLED touch screen. With an IP67 rating, it resists sweat and rain, making it suitable for workouts and daily wear. The band connects to Android phones (4.4+) via Bluetooth 4.0 BLE to deliver message notifications and sync data, powered by a 70mAh battery that provides up to 20 days of standby time, minimising how often you need to charge it.

Features and Construction

The Mi Band 2 is built around several key components that define its functionality and durability. Its construction uses specified materials for different parts, balancing functionality with everyday practicality for a wearable device.

Material and Build

The main unit housing incorporates plastic and aluminium, with the aluminium likely used for the charging contacts and structural elements. The wrist strap is made from thermoplastic elastomers, a material chosen for its flexibility, skin comfort, and resistance to moisture, which is important given the IP67 waterproof rating. This rating confirms the device is protected against dust ingress and can withstand immersion in up to 1 metre of water for 30 minutes, covering sweat, rain, and accidental splashes.

Size and Practical Fit

The total wrist strap length is 235mm, and it is adjustable to fit a circumference range from 155mm to 210mm, accommodating a wide variety of wrist sizes. The band secures with a buckle system integrated into the strap design. The main unit has a net weight of just 7g, contributing to its lightweight feel during all-day wear, whether you're working out, at work, or sleeping.

Uses and Placement

This device serves as both a dedicated fitness companion and a convenient notification hub, fitting into active and connected lifestyles. Its specific features support a range of common scenarios for users looking to monitor their activity and stay informed.

Event or Professional Use

For fitness activities, training, or sports, the optical heart rate sensor allows you to check your pulse on demand to gauge exercise intensity. The pedometer function tracks steps and general movement throughout the day using ADI ultra-low power acceleration sensors, helping you monitor daily activity levels. The IP67 waterproofing means it can be worn during sweaty gym sessions, runs in the rain, or for swimming where brief immersion may occur, without immediate damage.

Everyday Home Use

In daily life, the band's message push function delivers notifications for calls, texts, and app alerts directly to the OLED screen, so you can stay connected without constantly checking your phone. It also functions as a vibrating alarm clock, offering a discreet way to wake up or receive reminders. The long 20-day standby time means it can be worn continuously with minimal interruption for charging, integrating seamlessly into your routine.

Benefits and Buying Value

The Mi Band 2 offers practical advantages through its specific combination of features, battery performance, and build. Its value lies in providing multiple functions in a single, durable device with low maintenance needs.

Reuse and Low Maintenance

The device is designed for continuous, long-term use with minimal upkeep. The extended battery life reduces charging cycles, and the included charger makes topping up straightforward. The waterproof construction and sweat-resistant strap materials mean it can be worn in varied conditions and easily wiped clean, supporting reuse across different activities and environments without special care.
