Oura Ring 5 vs Ring 4: What This Smart Ring Comparison Is About
Oura Ring 5 vs Ring 4 is a head-to-head smart ring comparison that weighs a thinner, lighter design and upgraded health tracking accuracy against the previous model’s comfort, options, and lower price, helping buyers decide whether the new wearable ring upgrade is worth paying more for. Both generations are titanium sleep and health trackers that monitor heart rate, sleep stages, and daily readiness from the finger instead of the wrist. The Ring 4 has earned a reputation as a reliable, comfortable health companion with excellent battery life. The Ring 5 arrives as a premium upgrade, promising a more discreet fit and improved sensing powered by Oura’s health research. The key question is whether those incremental hardware and accuracy gains meaningfully improve everyday use enough to justify moving beyond the proven Ring 4.
Design and Comfort: Slimmer Ring, Tighter Sizing
On design, the Oura Ring 5 is a refinement rather than a reinvention. Oura says the new model is 40 percent thinner, measuring 0.24 inches wide by 0.09 inches thick versus the Ring 4’s 0.31 by 0.11 inches. Both are made of lightweight titanium and are water-resistant to 328 feet, but Ring 4 also offers a zirconia ceramic exterior for those who prefer a glossier jewelry look. Reviewers already found Ring 4 slim and comfortable for daily wear, though it could press uncomfortably during weight lifting, suggesting Ring 5’s lower profile may matter most to active users. The trade-off is sizing and styling flexibility: Ring 4 is sold in sizes 4 to 15, while Ring 5 narrows that to 6 to 13. Oura recommends a new sizing kit for Ring 5, even for existing owners, because the redesigned interior may fit differently.
Health Tracking Accuracy and Sensors: Finger vs Wrist
Health tracking accuracy is where Oura pushes the Ring 5 as a true wearable ring upgrade. Oura maintains that the finger is a better place to read biometric signals than the wrist because arteries there provide a cleaner pulse. The Ring 5 builds on this with precision low-profile sensor domes that improve skin contact, more powerful LEDs, and 12 stronger signal pathways designed to deliver clearer, more consistent readings across different finger shapes and skin tones. According to Oura, the ring’s optical sensors on the finger can provide a pulse signal “one hundred times stronger than at the wrist,” which is a bold claim aimed directly at smartwatches. Both generations tap into Oura’s long-running sleep and readiness algorithms, but Ring 5 brings the latest hardware and software tuning after 12 years of health sensing insights, promising more reliable data and more actionable in-app guidance.
Battery Life and Everyday Use: Incremental But Welcome Gains
Battery life has been a strong point for Oura, and Ring 5 aims to stretch it a little further. Oura estimates the Ring 5 at six to nine days per charge, compared with the Ring 4’s official five to eight days. In testing reported for Ring 4, the older model already managed a bit more than a week between top-ups, so Ring 5 will need to hit the higher end of its range in real-world use to feel like a clear win. The new ring uses a redesigned battery tailored to its thinner frame, and it still ships with a size-specific charging base. There is now an optional aluminum charging case accessory for Ring 5, which makes it easier to top up while traveling. For most users, both generations will outlast a typical smartwatch and suit overnight sleep tracking without frequent charging interruptions.
Price, Membership, and Upgrade Verdict for Ring 4 Owners
Price is where the Oura Ring 5 vs Ring 4 decision becomes difficult, especially for existing owners. The Ring 5 starts at USD 399 (approx. RM1,870), which is a USD 50 (approx. RM235) increase over the previous generation’s starting point. Higher-end Ring 5 finishes such as brushed silver, deep rose, gold, and stealth cost USD 499 (approx. RM2,335). Meanwhile, Ring 4 now represents better value: silver and stealth models start at USD 349 (approx. RM1,635), the gold finish is USD 399 (approx. RM1,870), and the extra-durable Ceramic versions in midnight and cloud are USD 399 (approx. RM1,870). Both rings require a USD 69.99 (approx. RM330) annual membership for full app features. For new buyers focused on comfort and the latest health tracking accuracy, Ring 5 is the premium choice. For Ring 4 owners, the slimmer fit and incremental sensing gains may not be enough to justify upgrading at current prices.
