Oura Ring 5 vs 4: What This Smart Ring Upgrade Means
Oura Ring 5 vs 4 is a direct health tracking comparison between two generations of smart rings that helps existing users decide whether the slimmer, more durable newer model offers enough value to justify an upgrade. Both rings track sleep, recovery, and daily readiness in a screen-free form factor, but Oura has redesigned the fifth-generation device to feel more like jewelry and less like a gadget. The new ring is 40% smaller than the Oura Ring 4, yet keeps multi-day battery life and sensor-packed internals. At the same time, health tracking capabilities remain very close, so the decision for Ring 4 owners comes down to design comfort, durability, added blood pressure tracking, and the cost of moving to the newer model.
Design and Comfort: Smaller, Thinner, More Inconspicuous
The headline difference in the Oura Ring 5 vs 4 debate is design. Oura Ring 5 is 40% smaller than Oura Ring 4, measuring 6.09mm wide and 2.28mm thick, which makes it much closer to a typical wedding band. That reduction in bulk means less grinding against adjacent fingers and a more discreet look, especially for users with smaller hands who found Ring 4 “a bit of a statement piece.” According to ZDNET, the new model aims to be “nearly indistinguishable from a wedding band,” shifting the ring from obvious tech to subtle accessory. Despite the slimmer profile, Oura preserved the screenless, minimalist style and multi-day wear comfort that define the platform. For a smart ring upgrade focused on daily wearability, the size and weight cuts are the most noticeable change Ring 4 users will feel immediately.
Durability, Battery Life, and Daily Wear
Durability is another key upgrade point. Oura Ring 5 adds a scratch-resistant vapor deposition coating on its titanium body and carries an IP68 rating, making it Oura’s most scratch-resistant ring yet. That is a meaningful improvement for users who routinely bump their ring on weights, countertops, or door frames. Android Authority notes that previous metallic Ring 4 models tend to show their wear over time, while the new finish options aim to stay cleaner for longer. Battery life also improves slightly: ZDNET reports Oura Ring 4 at about five to eight days per charge, while Ring 5 extends this to six to nine days. Oura says it achieved this by refining algorithms and adding more efficient hardware. Taken together, better coating, upgraded water and dust resistance, and a small battery bump make Ring 5 better suited for all-day, all-week wear.
Health Tracking Comparison and New Blood Pressure Features
From a health tracking comparison standpoint, Oura Ring 5 vs 4 is closer than the redesign might suggest. Both rings focus on sleep, recovery, and daily readiness, using finger-based sensors and multi-day data trends. Core metrics such as heart rate, temperature trends, and activity scores remain very similar across generations. The standout new feature for Ring 5 is passive blood pressure tracking, which adds another cardio-related data stream without needing a traditional cuff. This fits naturally alongside Oura’s existing emphasis on long-term health trends and stress markers. Otherwise, the user experience for daily health insights, readiness scoring, and guided insights stays consistent. For Ring 4 users happy with their current health dashboard, the new ring will feel more like a refinement than a reinvention, with blood pressure tracking as the most meaningful addition.
Should Oura Ring 4 Owners Upgrade to Ring 5?
The smart ring upgrade decision for current Oura Ring 4 owners comes down to how much they value comfort, durability, and passive blood pressure tracking. If Ring 4 feels bulky, looks too tech-forward on your hand, or shows heavy scratching, Ring 5’s smaller build and tougher coating will feel like a clear quality-of-life improvement. Users sensitive to battery anxiety may also appreciate the extra day of runtime. However, if you are satisfied with Ring 4’s fit and finish and mainly care about core health tracking metrics, the experience remains very close between both generations. The cost difference—Oura Ring 5 starting at USD 399 (approx. RM1,880) versus Oura Ring 4 at USD 349 (approx. RM1,640)—means you should weigh whether design and durability upgrades plus new blood pressure tracking justify that extra spend for your daily routine.
