What the Oura Ring 5 vs 4 Debate Is Really About
The Oura Ring 5 vs 4 comparison is a detailed smart ring comparison that weighs the slimmer design, small feature changes, and higher price of the Ring 5 against the still‑strong performance, comfort, and better value of the Ring 4 for people tracking sleep, recovery, activity, and stress every day. At its core, this Oura Ring upgrade question asks whether a 40% thinner profile, slightly tweaked internals, and projected battery gains are worth paying more when the older Ring 4 already feels sleek on the finger and covers the same core fitness ring features through the Oura membership. Both target the same users: people who want discreet wearable health data without a screen, but the decision splits into two groups—existing Ring 4 owners wondering about upgrading, and new buyers deciding which model deserves their money.
Design and Comfort: 40% Thinner, But Not a Total Redesign
Design is where the Oura Ring 5 pulls furthest ahead on paper. Oura says the Ring 5 is 40% thinner than the Ring 4, measuring 0.24 inches wide by 0.09 inches thick versus 0.31 by 0.11 inches. Both models use titanium and are water‑resistant to 328 feet, so durability and swim‑friendliness are comparable. The Ring 4 was already slim with minimal sensor bumps and feels comfortable for daily wear, though reviewers noted it can get in the way when lifting weights. The thinner Ring 5 should reduce that bulk feeling, which matters if you grip barbells often or dislike jewelry catching. However, Ring 4 offers more sizes (4–15 versus 6–13) and an extra zirconia ceramic option, making it friendlier for very small or large fingers and for people who care about materials more than shaving off fractions of a millimeter.
Price and Value: Premium Oura Ring Upgrade or Overpriced Refresh?
Price is the main reason many buyers hesitate. The Oura Ring 5 starts at USD 399 (approx. RM1,840), while the Oura Ring 4 starts at USD 349 (approx. RM1,610) in the remaining silver and stealth finishes. Premium colors on the Ring 5 jump to USD 499 (approx. RM2,300), whereas the gold Ring 4 now costs USD 399 (approx. RM1,840), and the extra‑durable Ring 4 Ceramic in midnight or cloud is also USD 399 (approx. RM1,840). Both rings require a USD 69.99 (approx. RM320) annual membership for most app features, so subscription cost does not favor either model. According to PCMag, “The Oura Ring 4 remains the better value,” because it delivers nearly the same experience for less money. For budget‑conscious buyers or those unsure about smart rings, the Ring 4’s lower entry price and discounted finishes are compelling.
Battery Life and Fitness Ring Features: Subtle Differences, Similar Experience
On paper, the Oura Ring 5 promises slightly longer battery life, with an estimated six to nine days per charge versus five to eight days for the Ring 4. In testing, the Ring 4 already reached a bit over a week, so the Ring 5 must hit the top of its range to stand out. Both charge on size‑specific bases, and both can use the optional aluminum charging case, which adds about a month of backup power. In terms of fitness ring features, the overlap is extensive: each tracks blood oxygen, heart rate, heart rate variability, respiratory rate, skin temperature, daily movement, exercises, sleep duration and stages, and stress levels. The Ring 5 squeezes redesigned internals into its smaller frame and drops from 18 to 12 signal pathways, but Oura claims higher precision from its new sensor layout rather than a big feature list change.
Who Should Buy Which: Existing Owners vs First‑Time Buyers
For current Ring 4 owners, the Oura Ring upgrade question is tough. The day‑to‑day smart ring experience—sleep insights, readiness, activity tracking—remains broadly similar. Unless the Ring 4 feels bulky during workouts or you are highly sensitive to ring thickness, the gains from moving to Ring 5 look incremental rather than transformational. New buyers face a cleaner choice. If you want the sleekest profile, are drawn to the latest design, and do not mind paying more upfront, the Ring 5 is the most refined option and may prove slightly more comfortable. If you care more about value, wider sizing, and ceramic finishes, the Ring 4 is still an excellent performer. For most people, the smarter move is to pick based on price, fit, and style rather than chasing small sensor and battery tweaks.
