The latest smartwatch from Chinese company Zepp Health’s Amazfit brand has a powerful battery and a wide range of health features.

The compact Amazfit GTS 4 Mini has a slim and light design, and is enhanced by the brand’s easy-to-use health management features, a 15-day battery life and the Zepp OS operating system.

Featuring the brand’s self-developed BioTracker 3.0 PPG biometric optical sensor, the watch lets users monitor their blood-oxygen saturation, heart rate and stress level 24 hours a day, and measure these three metrics simultaneously in one tap for results in as little as 45 seconds.

It also features the PAI health assessment system for a simplified overview of the wearer’s health status, along with menstrual cycle tracking that provides timely predictions and reminders of upcoming cycles. Users can check their sleep data quickly, easily and directly on the watch display, and receive reminders for abnormally high or low heart rates, low SpO₂ levels and high stress levels, which will prompt the user to perform the smartwatch’s built-in stress-reducing breathing exercise.

The 9.1mm watch body weighs 19g without the strap, and integrates a metallic middle frame. Its enlarged 4.2cm HD AMOLED display is crafted from curved glass and devotes more screen space to user data, with its 70.2% screen-to-body ratio. Various stylish watch faces with matching always-on displays are available to add personality, and the skin-friendly silicone strap is said to combine beauty, comfort and practicality.

With a battery capacity of 270mAh, the watch can be used for up to 15 days with typical usage from a full-charge, and even up to 45 days while on battery saver mode.

There is a selection of more than 120 sports modes, and it can automatically recognisze seven sports movements. The brand’s popular PeakBeats workout status algorithm is ready to help users review performance data such as VO₂ max and training load.

This smartwatch supports five satellite positioning systems, with performance and accuracy that’s enhanced by Amazfit’s patented circularly-polarised antenna technology. It is water resistant.

The Zepp OS features smooth animations and a tailored UI that allow seamless navigation while consuming less battery power. The mini app ecosystem includes over ten mini apps and Amazon Alexa is built-in for selective regions.

It comes in four colours – Midnight Black, Flamingo Pink, Mint Blue,and Moonlight White. The smartwatch is available at the Amazfit US store for $120 and will roll out soon in other regions.
