Oura Launches $399 Ring 5, Shrinking Smart Ring Volume 40% and Extending Battery Life to 9 Days

Summary
Oura’s Ring 5 replaces the Ring 4 at $399, cutting volume by 40% to a 2g design that the review says now feels closer to a standard wedding band than a gadget.
Battery life rises despite the smaller body, with Oura rating the ring for 6 to 9 days between charges; the tested size 8 lasted just under eight days, about two days longer than the comparable Ring 4.
The titanium ring still tracks more than 50 health metrics — including heart rate, blood oxygen, temperature and motion — while Oura’s app and AI Advisor add analysis, illness signals and extensive women’s health features.
The trade-off remains cost and lock-in: full features require a $5.99 monthly subscription, workout tracking still leans on a phone, and the non-repairable ring has a non-replaceable battery.
