What we like about Haylou Solar

  • Exceptional value for money with a premium-feeling metal frame design
  • Long battery life, often lasting 10-20 days depending on usage and settings
  • Lightweight and comfortable for all-day wear
  • IP68 dust and water resistance allows for worry-free use in rain or during workouts
  • Crisp and bright display (especially on AMOLED models like Solar Pro and 5)
  • Reliable basic health tracking for steps, heart rate, and sleep

What we don't like about Haylou Solar

  • No built-in GPS; requires a tethered smartphone for outdoor route tracking
  • The Haylou Fun/Fit app is considered barebones and less feature-rich than competitors like Mi Fit
  • Limited customisation for watch faces and menu widgets
  • Notifications can be inconsistent, occasionally failing to display icons or full message text
  • Proprietary magnetic charging cables are not always interchangeable between different Solar models
  • Heart rate accuracy can struggle during high-intensity or sudden interval training

Verdict

The Haylou Solar (LS05) is a budget-friendly smartwatch featuring a minimalist round metal body and a 1.28-inch TFT-LCD touch display with a 240x240 resolution. It includes an optical heart rate sensor, accelerometer, and 12 dedicated sport modes such as running, cycling, and yoga, all protected by an IP68 waterproof rating. Main pros include its impressive 340mAh battery that delivers up to 15 days of life with 24/7 heart rate tracking (or 30 days standby), a premium-feeling metal frame, and lightweight comfort for sleep tracking. Significant cons include the lack of built-in GPS, limited watch face customization, and a display that can be difficult to read in direct sunlight compared to AMOLED alternatives.
