Strengths and limitations

  • On GIGAZINE's 41 mm watch with the always-on display, the battery fell from full to 50% in about 17 hours and to 0% in about 34 hours, above Google's 30-hour figure. Charging reached 89% in 30 minutes and 100% in 44 minutes. The team says the curved glass stays readable at low angles and sleep tracking gave nearly the same results as an Apple Watch Ultra 2; they found the silicone band sweaty.
