Third-party reviews

What we like about Zepp E Square

  • Elegant, ultra-slim stainless steel design with a premium feel
  • Vibrant and sharp 1.65-inch AMOLED display with high pixel density (341 ppi)
  • Impressive battery life, typically lasting 5 to 7 days on a single charge
  • Lightweight and comfortable enough to wear all day and while sleeping
  • Comprehensive health tracking features, including SpO2, heart rate, and stress monitoring
  • Smooth and responsive user interface with an intuitive companion app
  • Water-resistant up to 5ATM, making it suitable for swimming

What we don't like about Zepp E Square

  • Lack of built-in GPS, requiring a tethered smartphone for location tracking
  • Limited smart features: no third-party app store, no NFC for payments, and no speaker/microphone for calls
  • Proprietary magnetic charger is necessary and can be easily forgotten
  • Notification system is basic, with no ability to reply to messages directly from the watch
  • The default leather and fluoroelastomer straps are frequently described as uncomfortable or flimsy
  • Higher price point compared to competitors with more advanced features
  • No dedicated night mode, which can lead to the screen accidentally lighting up during sleep

Verdict

The Zepp E Square is a premium lifestyle smartwatch featuring a 1.65-inch always-on AMOLED display with 341 ppi resolution, housed in a slim 9.1mm stainless steel chassis with 3D curved bezel-less glass. Key specifications include 5 ATM water resistance, SpO2 blood-oxygen monitoring, and 11 sports modes, powered by a 188mAh battery offering up to 7 days of typical use. While it excels with its elegant design and vivid screen, it lacks integrated GPS, a built-in speaker for calls, and a wide ecosystem of third-party apps.
