Oura Ring 5 vs Ring 4: What This Smart Ring Upgrade Is About
Oura Ring 5 vs Ring 4 is a smart ring upgrade comparison that weighs slimmer hardware, fresh ergonomics, and small performance gains against similar core health tracking and a higher starting price. Both generations focus on continuous health insights, but Oura Ring 5 arrives as a complete redesign that is 40% smaller than Oura Ring 4 and aims to feel more like jewelry than a gadget. The main question is not whether Ring 5 is better on paper—it is—but whether its design refinements, modestly longer battery life, and sensing tweaks are meaningful enough for existing Ring 4 owners to switch. New buyers face a different decision: is the sleeker Ring 5 worth paying more for than the still-capable Ring 4, given that most of Oura’s newest health software already runs on both devices?
Design and Comfort: A Slimmer Ring That Feels More Like Jewelry
Design is where the Oura Ring 5 upgrade is most obvious. Oura says Ring 5 is 40% smaller than Ring 4, shrinking from 7.99mm wide and 2.88mm thick to 6.09mm wide and 2.28mm thick. In use, that slimmer profile lets fingers close more naturally and makes Ring 5 far less noticeable during sleep, strength training, and everyday tasks. According to ZDNET, Oura Ring 5 is “significantly thinner, nearly indistinguishable from a wedding band,” which will appeal to anyone who disliked earlier chunky smart rings. Athletech News notes that the redesigned sensing architecture uses low-profile domes and more powerful LEDs, helping the ring stay accurate despite its smaller size. The trade-off is sizing: Ring 4 covers sizes four through 15, while Ring 5 is limited to six through 13, so people with very small or large fingers may still need Ring 4.
Health Tracking Comparison: Similar Core Data, Subtle Gen 5 Advantages
For health tracking comparison, both Oura Ring 5 and Ring 4 deliver broadly similar capabilities: sleep insights, readiness scores, activity tracking, and continuous health trends. The bigger shift is the platform itself. Features like Health Radar, Health Records integration, GLP-1 Insights, lab uploads, and AI-enabled care through Counsel Health are rolling out across generations, so Ring 4 owners gain most new tools through software. Athletech News reports that Oura redesigned Ring 5’s sensing system with more powerful LEDs and improved signal pathways, and the reviewer saw faster, more accurate activity classification, especially differentiating walks, strength work, Pilates, and HIIT. Still, these improvements feel incremental rather than transformational for many users. If your main concern is access to Oura’s latest health features, a Ring 4 paired with the updated app remains highly capable and far from obsolete.
Battery Life, Durability, and Daily Wear
Battery and durability shape how a smart ring fits into everyday life. Oura Ring 4 is rated for about five to eight days per charge, while Ring 5 extends that to six to nine days thanks to a new battery and more efficient algorithms. ZDNET notes that Oura users have reported battery issues with Ring 4, and Oura says it re-engineered Ring 5 to improve longevity on the smaller device. On durability, Ring 5 uses titanium with a scratch‑resistant vapor deposition coating, which Oura calls its most scratch‑resistant ring yet, plus an IP68 rating. In practice, the slimmer Ring 5 form factor also helps with durability: the Athletech News reviewer wore it through HIIT and lifting without it catching on dumbbells, a common irritation with older models. For people who wear their ring nonstop, these quality‑of‑life gains may matter more than any algorithm tweak.
Price-to-Feature Value: Should You Upgrade or Start with Ring 5?
Oura Ring 5 starts at USD 399 (approx. RM1,880), compared with Oura Ring 4’s starting price of USD 349 (approx. RM1,645), and premium Ring 5 finishes reach USD 499 (approx. RM2,355). Both generations require a subscription for full app access, with ZDNET citing a USD 70 (approx. RM330) annual fee. For new buyers, the slimmer design, slight battery bump, and more wearable feel make Ring 5 the better long‑term bet if budget allows. Existing Ring 4 owners face a narrower value gap. Because most of Oura’s newest health features arrive via software, you should upgrade only if the smaller, more jewelry‑like body, tougher coating, and modest battery gains solve real pain points. If you are happy with Ring 4’s fit and battery, and your size is not restricted on Ring 5, staying put and letting the app evolve may be the smarter smart ring upgrade strategy.
