Leaks gave a quick preview of the Oura Ring 5, but it wasn’t clear just how much thinner the new model is. The $50 price jump is now confirmed for Oura’s new wearable that tracks enhanced blood pressure patterns and live activity, now.
At 6.09mm wide and 2.28mm thick, the Oura Ring 5 is a full 40% smaller than the Oura Ring 4. Size was one of the biggest points of contention for a wearable that outperforms a lot of other devices in the same form. That size difference is considerable when factoring in Oura’s claim that the new ring is rated for a full week of use, or 6 to 9 days.
The physical size difference seems to mean little to battery life, as a full week would be a big jump if it translates to real-world use. In Oura’s visual comparison, the disparity between models looks huge.
Oura Ring 5 compared to Oura Ring 4
Within the new, thin Oura Ring 5 is a new set of sensors that Oura says are built for better accuracy. Each has new sensor domes with stronger LEDs to improve data consistency. On paper, heart rate readings are 99% accurate, and sleep data is 95% accurate.
