What we like about Huami Amazfit 2

  • Premium design with high-quality materials like ceramic bezels and carbon fiber finishes.
  • Excellent outdoor screen visibility thanks to the transflective LCD technology.
  • Extensive fitness tracking capabilities, including support for over 14 sports modes and triathlon tracking.
  • Strong battery life, typically lasting around 5 days on a single charge.
  • Onboard music storage allows users to listen to music via Bluetooth headphones without a phone.
  • Highly competitive price point for the level of features offered.

What we don't like about Huami Amazfit 2

  • Display appears dull, fuzzy, or difficult to read in low-light indoor environments.
  • Large and bulky physical profile can be uncomfortable for users with smaller wrists.
  • Heart rate monitoring and sleep tracking can be inaccurate or inconsistent compared to dedicated medical devices.
  • The user interface and operating system can feel laggy or unpolished.
  • Limited smart features, such as the inability to reply to notifications directly from the watch.
  • GPS synchronisation can sometimes be slow to lock on before starting a workout.

Verdict

The Huami Amazfit 2, widely known as the Amazfit Stratos, is a sports-focused smartwatch featuring a 1.34-inch transflective 'always-on' display (320x300 resolution) that excels in direct sunlight, protected by a ceramic bezel and carbon fiber-reinforced housing. It is powered by a 1.2 GHz dual-core processor with 512MB RAM and 4GB of internal storage (approximately 2GB user-accessible for MP3 music), offering built-in GPS/GLONASS, a PPG heart rate sensor, and 5 ATM water resistance suitable for swimming. Key pros include its premium design, accurate outdoor tracking for over 10 sport modes, and a 5-day battery life; however, it is frequently criticized for its bulky 48mm size, lackluster display performance in low-light conditions, and occasional inaccuracies in high-intensity heart rate monitoring.
