- Oura Ring 5Yes
The Oura Ring 5 lasts about a week per charge, per BGR's review.

How we know (2 sources)
Months-long review of the RingConn Gen 2 Air ($199, no subscription): detailed sleep tracking (REM, heart rate, respiratory rate, HRV), 24/7 vitals, over a week of battery (ten-day rating), 100 m water resistance. Limited fitness tracking; protruding inner sensors are a little uncomfortable.
Read the sourceReview of the Oura Ring 5: much smaller titanium ring, $399 (Black, Silver) to $499 for other finishes, plus $5.99/month membership that unlocks most features, so about $470 in year one. About a week of battery. Sleep and recovery analysis among the best; new blood pressure and breathing trend features have little independent validation and are not diagnostics. Not a medical device.
