What we like about Amazfit GTS 4

  • Excellent battery life, typically lasting about a week under normal usage.
  • Sleek and lightweight design that feels premium and resembles the Apple Watch.
  • Vibrant 1.75-inch AMOLED display that is bright and clear even in sunlight.
  • Highly accurate dual-band GPS performance for tracking outdoor activities.
  • Intuitive and responsive user interface following recent software updates.
  • Good value for money compared to higher-priced competitors like the Apple Watch.

What we don't like about Amazfit GTS 4

  • Lack of support for third-party apps, limiting its overall smartwatch versatility.
  • Inconsistent heart rate tracking during high-intensity workouts.
  • Absence of NFC for contactless payments (e.g., Google Pay or Apple Pay).
  • Zepp companion app can be convoluted with some garbled translations.
  • Inaccurate sleep and nap tracking, often failing to distinguish between being awake and light sleep.
  • Limited notification interaction, with no ability to send custom text replies on certain platforms.

Verdict

The Amazfit GTS 4 is a premium fitness-oriented smartwatch featuring a vibrant 1.75-inch AMOLED display with a 390 x 450 resolution and an always-on mode, housed in a lightweight 27g aluminium alloy frame. It stands out with its industry-first dual-band circularly-polarized GPS antenna for high positioning accuracy, 150+ sports modes with smart recognition of 8 sports, and the BioTracker 4.0 PPG biometric sensor for 24-hour monitoring of heart rate, SpO2, and stress. Main pros include a solid 8-day battery life under typical usage, built-in Alexa, and the ability to store music and answer Bluetooth phone calls directly via its integrated speaker and microphone. However, notable cons include the lack of third-party app support (e.g., Spotify), no mobile payment functionality, and occasional inaccuracies in automatic rep counting and sleep tracking.
