Oura Ring 5 vs Ring 4: What This Smart Ring Upgrade Is About
Oura Ring 5 vs Ring 4 is a direct comparison between two generations of Oura’s smart rings, helping existing Ring 4 users decide if a slimmer design, durability upgrades, and new blood pressure tracking features are worth the cost and effort of upgrading their everyday health tracker. At a glance, this Oura Ring comparison shows the Ring 5 as a refinement, not a full reinvention, with the same core focus on sleep, readiness, and activity scores. Both rings target people who want detailed health data without a screen on their wrist, but the Ring 5 adds a more discreet look and some meaningful hardware tweaks that may appeal strongly to long-term users who wear their smart ring around the clock.
Design and Comfort: Slimmer, Lighter, More Discreet
The biggest visible change in the Oura Ring 5 vs Ring 4 debate is design. Oura Ring 5 is 40% smaller than Ring 4, measuring 6.09mm wide and 2.28mm thick, making it closer to a classic wedding band than a chunky gadget. Weight drops as well, from 3.3–5.2g on Ring 4 to 2–2.69g on Ring 5, depending on size. According to ZDNET, the new model is “significantly thinner, nearly indistinguishable from a wedding band.” That matters if your Ring 4 feels bulky during sleep, workouts, or daily tasks like driving. Android Authority’s reviewer notes that smaller rings grind less against adjacent fingers and feel less intrusive in the shower or while carrying things. If comfort and subtle style are your top priorities, the design alone is a strong reason to consider this smart ring upgrade.
Durability and Battery Life: Everyday Wear Gains
Durability is another clear win for the newer model. Oura Ring 5 keeps the titanium base but adds a scratch-resistant vapor deposition coating, which Oura calls its most scratch-resistant ring yet. This aims to address complaints from Ring 4 users whose metallic finishes picked up marks from weight training, housework, and general bumps. Android Authority highlights that ceramic versions stayed cleaner, while metallic Ring 4 models “look exactly like I’ve been wearing it while lifting weights.” On the battery side, Oura Ring 5 is rated for six to nine days per charge, compared to five to eight days on Ring 4. ZDNET reports that Oura re-engineered the hardware with more powerful LEDs, a new battery, and more efficient algorithms to extend runtime without enlarging the ring. For heavy daily wear, these durability and battery tweaks can meaningfully improve the experience.
Health Tracking and New Blood Pressure Feature
From a pure health tracking performance standpoint, Oura Ring 5 vs Ring 4 is surprisingly close. Both rings focus on sleep staging, readiness scoring, and activity tracking using similar sensor layouts and Oura’s mature algorithms. Early hands-on impressions suggest that day-to-day health metrics remain broadly consistent between generations, so you should not expect a huge leap in accuracy moving from Ring 4 to Ring 5. The standout change is the introduction of passive blood pressure tracking on Ring 5, giving it a fresh health metric that Ring 4 owners will miss. While full real-world testing is still developing, this capability points toward richer cardiovascular insights over time. If you are specifically interested in blood pressure tracking and long-term heart health trends, that single feature could be a decisive factor in choosing the newer smart ring upgrade.
Should You Upgrade from Oura Ring 4 to Ring 5?
For most existing users, the Oura Ring 5 vs Ring 4 decision comes down to comfort, appearance, and your interest in new capabilities. If you find Ring 4 bulky, notice it constantly during sleep or workouts, or hate how scratched your metallic model looks, Ring 5’s 40% smaller build, lighter weight, and upgraded coating make a compelling smart ring upgrade. You also gain slightly longer battery life and future-facing features like passive blood pressure tracking. On the other hand, if your Ring 4 still fits well, your size falls outside Ring 5’s range, or you are content with its health metrics, staying put is reasonable since core tracking performance remains very close. In short: upgrade for better feel, polish, and added blood pressure insights, not because you expect a completely different health data experience.
