Oura Ring 5 Shrinks 40% and Adds 1 Day of Battery Life

3 articles · Updated · ZDNet · Jul 1

Summary

  • ZDNET’s monthlong test found the Oura Ring 5’s main upgrade is hardware: a design 40% smaller than the Ring 4 that made it feel more discreet and jewelry-like.
  • Battery life also improved by about one day in the review, lasting roughly six days versus about 5.5 days for the prior model, though the gain can vary by ring size.
  • Software changes were more incremental, with GLP-1 insights joining recent app additions such as live activity tracking and lost-device location tools.
  • Oura is also preparing Health Radar—an opt-in feature due by July 8, 2026—to track cardiovascular strain, blood pressure health and nighttime breathing over 30 days.
  • The review said buyers are paying about $50 more for largely the same core experience, making the thinner form factor the clearest reason to upgrade.
