Whether you’re an athlete, a tech enthusiast, or someone looking for a versatile smartwatch that won’t break the bank, the GTR 4 brings a compelling blend of design, performance, and battery life — all at a competitive price point.
Lets dive into the deeper aspects of the Amazfit GTR4.
Design & Build Quality
- Elegant yet sporty design: The GTR 4 features a 46mm aluminum case with angular ridges and a matte finish, offering a premium look. The rotating crown (with a red accent) and a secondary button provide tactile navigation 46.
- Display: A 1.43-inch AMOLED screen (466×466 pixels, 326 PPI) with vibrant colors and minimal bezels. However, the glass lacks scratch resistance—consider a screen protector 68.
- Straps: Comes with a 22mm quick-release strap (options include leather and fluoroelastomer). Some users find the default strap cheap, but it’s easily replaceable 47.
- Durability: 5ATM water resistance for swimming, but the aluminum case and glass are prone to scratches during rugged activities 6.
Performance & Software
- Zepp OS 2.0: A significant upgrade over older Amazfit OS, offering smoother animations, customizable widgets, and a small app store (e.g., calculators, GoPro remote). Lacks third-party app support like Spotify 16.
- Smart Features:
- Notifications: Supports text replies (canned responses/emojis) and long email previews. No image display or unread notification indicator 1.
- Alexa Integration: Voice control for smart home commands and basic queries. Offline voice assistant for watch controls (limited to 4 languages) 17.
- Bluetooth Calling: Built-in mic and speaker work well indoors but struggle outdoors 5.
Fitness & Health Tracking
- Dual-Band GPS: Industry-leading accuracy with a circularly polarized antenna, outperforming many pricier watches (e.g., close to Garmin Forerunner 955) 67.
- 150+ Sports Modes: Includes auto-detection for 8 activities (running, cycling, etc.). Strength training mode tracks reps and exercises (e.g., squats, bench presses) 56.
- Health Sensors:
- BioTracker 4.0 PPG: Improved heart rate and SpO2 monitoring (33% more data than previous gen). Stress tracking requires manual activation 27.
- Sleep Tracking: Analyzes light/deep/REM sleep, respiratory rate, and breathing quality. Naps ≥20 minutes are logged 56.
- PAI Score: A holistic health metric combining activity, heart rate, and other data 7.
Battery Life
- Up to 14 days (normal use) or 7 days (heavy use with always-on display/GPS). With moderate use, users report 9–10 days 47.
- GPS Modes:
- 25 hours (dual-band GPS) / 44 hours (standard GPS) for endurance athletes 7.
