Third-party reviews

What we like about Amazfit GTS 3

  • Sleek, lightweight design often compared to the Apple Watch
  • Vibrant and sharp AMOLED display with high outdoor visibility
  • Affordable price point compared to high-end competitors
  • Comprehensive health tracking including SpO2, heart rate, and sleep
  • Smooth and intuitive user interface with Zepp OS
  • Accurate built-in GPS for tracking outdoor activities

What we don't like about Amazfit GTS 3

  • Battery life is significantly lower than the claimed 12 days, typically lasting 4-6 days with features enabled
  • Lack of essential smart features like NFC for payments and local music storage
  • No built-in speaker, preventing the ability to take phone calls or hear Alexa responses
  • Very limited selection of third-party apps in the Zepp App Store
  • Occasional software stability issues, including system freezes or restarts
  • Setup process can be lengthy and sometimes unintuitive

Verdict

The Amazfit GTS 3 is a sleek, lightweight smartwatch featuring a 1.75-inch Ultra HD AMOLED display with 341 PPI and up to 1,000 nits brightness, encased in an 8.8mm aircraft-grade aluminium alloy body weighing just 24.4g. Running on Zepp OS, it offers over 150 sports modes, 5 ATM water resistance, and high-precision GPS supporting five satellite systems. Key pros include a dedicated physical crown for navigation, 'one-tap' measurement of four health metrics (heart rate, SpO2, stress, and breathing rate), Alexa integration, and a battery life of up to 12 days. However, notable cons include the lack of a built-in speaker for phone calls, no local music storage, and the absence of NFC for contactless payments.
