The Amazfit GTS 4 Mini emerges as a compelling proposition in the crowded smartwatch market, masterfully blending a sleek, compact form factor with a surprisingly robust set of health and fitness features. It carves a niche for users who prioritize subtlety and comfort without wanting to compromise on actionable health data or smart connectivity. This device is a testament to the idea that powerful technology can indeed be packaged in an elegant, lightweight design.
Craftsmanship and comfort are immediately apparent. The watch features a lightweight aluminum alloy case that is both durable and aesthetically pleasing, available in a range of colors like Midnight Black, Misty White, and Blooming Pink. Its slim profile, measuring just under 10mm in thickness, allows it to slide effortlessly under shirt cuffs, making it suitable for 24/7 wear. The hallmark of the GTS 4 Mini is its compact, rectangular 1.65-inch AMOLED display. This screen is a visual treat, offering vibrant colors, deep blacks, and exceptional brightness levels that remain legible even under harsh sunlight. With a sharp resolution and thin bezels, the display provides an immersive canvas for watch faces and data. It is protected by 2.5D tempered glass with an anti-fingerprint coating, enhancing durability and maintaining a clean look. The included silicone strap is soft, hypoallergenic, and features a quick-release mechanism, allowing for effortless personalization to match style or activity.
Beneath its stylish exterior lies a comprehensive health monitoring ecosystem, anchored by Zepp Health’s advanced BioTracker™ 4.0 PPG biometric sensor. This enables 24/7 heart rate monitoring, alerting users to abnormally high or low heart rates. Blood oxygen saturation (SpO2) measurements can be taken on demand, providing insights into overall wellness and recovery, particularly useful during high-altitude activities or for monitoring general respiratory health. A standout feature is the round-the-clock stress monitoring system. The watch analyzes heart rate variability (HRV) to assess stress levels and offers guided breathing exercises to help users manage moments of acute tension, promoting mental well-being directly from the wrist. For women’s health, the integrated period tracker allows for logging cycles, predicting fertile windows and upcoming periods, and sending discreet reminders. Sleep tracking is detailed, breaking down sleep stages (light, deep, REM) and providing a sleep score and personalized suggestions for improvement. The watch even monitors nighttime breathing patterns, adding another layer of health oversight.
As a fitness companion, the Amazfit GTS 4 Mini is remarkably capable for its size. It comes preloaded with over 120 sports modes, covering everything from mainstream activities like running, cycling, and swimming to more niche pursuits like jump rope, martial arts, and even dancing. For core workouts, it automatically recognizes four common exercises: outdoor running, walking, treadmill, and indoor cycling, seamlessly starting and stopping tracking without user intervention. During GPS-enabled activities, the watch connects to multiple satellite systems (GPS, GLONASS, Galileo, BDS) to accurately map routes, track distance, and monitor pace. With 5 ATM water resistance, it is fully protected for swimming in pools and shallow waters, automatically tracking swim metrics like laps, stroke type, and SWOLF efficiency. Post-workout, the Zepp App provides in-depth analysis, including training load, effect, and recovery time, helping users optimize their routines and avoid overtraining.
Smart functionality is thoughtfully integrated to keep users connected without being overwhelming. Notifications for calls, texts, and apps from a paired smartphone are displayed clearly on the bright screen, with quick options to dismiss them. The watch allows for music control, enabling users to play, pause, or skip tracks on their phone directly from their wrist. A find-my-phone feature offers practical utility. While it lacks built-in storage for music or contactless payments, its core smart features are focused and reliable. It also includes handy tools like a weather forecast, alarm clock, stopwatch, and countdown timer.
The battery life of the Amazfit GTS 4 Mini is a significant strength. In typical usage with heart rate monitoring and notifications enabled, it can easily last up to 15 days on a single charge, minimizing the hassle of frequent charging. With heavy use, including regular GPS workouts, battery life extends to approximately 7-10 days. In a basic watch mode, it can survive for up to 45 days. This endurance is achieved through power-efficient processors and display technology, ensuring the device remains a constant companion rather than a daily chore. Charging is via a proprietary magnetic puck that snaps securely to the back of the watch.
The user experience is governed by Zepp OS, a lightweight and fluid operating system designed for efficiency and smooth navigation. Interactions are primarily through intuitive touchscreen swipes and taps, supplemented by a single functional button on the side for quick access to the app list and to power functions. The Zepp App serves as the comprehensive hub for all data, offering detailed historical trends, insights, and device customization. Here, users can browse and download a vast library of customizable watch faces to match any style or mood. The app’s interface is clean, well-organized, and makes delving into health metrics both accessible and engaging.
In essence, the Amazfit GTS 4 Mini successfully executes a delicate balance. It avoids the common pitfall of sacrificing substantial features for the sake of a smaller design. Instead, it packs a high-resolution AMOLED display, extensive health monitoring tools including stress and SpO2 tracking, robust multi-sport GPS functionality, and exceptional battery life into a chassis that is discreet, fashionable, and comfortable for all-day, everyday wear. It caters to a user who desires a smartwatch that complements their lifestyle rather than dominating it, providing meaningful health insights and connected convenience without unnecessary bulk or complexity. For those seeking a powerful yet unobtrusive wearable, the GTS 4 Mini presents a compelling, value-driven option that punches well above its weight class in both design and performance.
