Xiaomi Mi Band 1S Optical Heart Rate Fitness Wristband with 10-Day Standby and Sleep Monitoring

The Xiaomi Mi Band 1S combines practical health tracking with everyday convenience in a lightweight, water-resistant design. Its optical heart rate sensor uses PPG technology to give you clear, real-time readings directly on the wrist. With up to 10 days of standby from a 45mAh battery, this band keeps going without daily charging. It monitors steps, distance, calories, and sleep patterns, helping you build consistent habits. Call reminders and a silent alarm ensure you stay on schedule. The IP67 rating protects against splashes and dust, making it suitable for active use.

Features and Construction

The Mi Band 1S is built around a magnesium-aluminium alloy case and a flexible TPSiV band. Its compact dial and adjustable strap offer a comfortable fit for most wrists. The device uses Bluetooth 4.0 to sync with the Mi Fit app on Android and iOS.

Material and Build

The case is made from magnesium-aluminium alloy, providing strength while keeping weight to just 14g. The band material is TPSiV, a thermoplastic silicone vulcanizate that feels soft against the skin and resists wear from daily use. The elliptical dial measures 1.36 x 3.7 cm with a thickness of 0.99 cm.

Size and Practical Fit

The band width is 1.3 cm and fits wrists from 15.7 to 20.5 cm in circumference. The lightweight design means you may forget you are wearing it, making it practical for all-day and night use. The IP67 waterproof rating allows brief submersion in fresh water up to 1 metre.

Uses and Placement

Whether you are starting a fitness routine or simply want to keep an eye on your daily activity, the Mi Band 1S fits into a variety of lifestyles. It works as a step counter, heart rate tracker, and sleep monitor without requiring constant phone checks.

Event or Professional Use

Use the silent alarm for a gentle vibration-based wake-up that won't disturb others. The call reminder function means you can keep your phone on silent in meetings but still know when important calls come in. The phone unlock feature saves you from typing passwords repeatedly when your phone is nearby.

Everyday Home Use

Track your daily step count and distance walked around the house or on errands. Let the band monitor your sleep quality, with data on deep and shallow sleep phases. The 10-day standby time means less frequent charging, so it stays ready for your daily routine.

Benefits and Buying Value

The Mi Band 1S delivers core fitness tracking features in a compact, low-maintenance package. Its long battery life and straightforward operation reduce the hassle of managing another device.

Reuse and Low Maintenance

The 45mAh battery lasts up to 10 days between charges, so you only need to recharge once every week and a half. The band material is designed to withstand regular wear, and the IP67 rating means you can wash your hands or get caught in the rain without removing it.
