Oura Ring 5 vs Ring 4: What This Comparison Is About
The Oura Ring 5 vs Ring 4 comparison is an evaluation of two generations of Oura’s smart rings that examines whether the slimmer design, durability upgrades, and new health monitoring tools make the latest model a worthwhile upgrade for existing users and a better choice for new buyers. Both rings focus on wearable health monitoring in a discreet form factor, tracking sleep, recovery, and daily readiness. The Oura Ring 4 is already a capable smart ring, but it feels chunky on many hands and raises some long‑term durability and battery concerns. The Oura Ring 5 answers these complaints with a smaller build, refined materials, and efficiency improvements, while keeping Oura’s core tracking features intact. This smart ring comparison focuses on those incremental but important changes rather than a complete reinvention.
Design and Comfort: A Much Slimmer Smart Ring
If comfort and subtle styling drive your Oura Ring 5 upgrade decision, the new design is the headline change. Oura Ring 5 is 40% smaller than Oura Ring 4, trimming down to 6.09mm wide and 2.28mm thick, compared to the older ring’s 7.99mm width and 2.88mm thickness. According to ZDNET, this gives Oura Ring 5 a profile that is “nearly indistinguishable from a wedding band,” making it less conspicuous and easier to pair with other jewelry. Android Authority’s hands‑on experience with Ring 4 highlights how chunkier rings can grind against adjacent fingers, become distracting overnight, and even feel awkward during showers or workouts. The smaller Ring 5 aims to fix those pain points while retaining its screenless, passive feel. For petite hands or anyone who dislikes bulky tech, this size reduction alone may justify an upgrade.
Durability, Battery Life, and Build Quality
Durability has been a recurring concern for long‑term Oura Ring 4 users, especially those who wear their ring through weight training and daily chores. Oura Ring 5 addresses this with a titanium body and a new scratch‑resistant vapor deposition coating, which Oura calls its most scratch‑resistant ring yet. Its IP rating is also listed as IP68, improving resistance to water and dust over previous wording. On the battery side, Oura Ring 4 typically delivered around five to eight days per charge, while Oura Ring 5 is rated for six to nine days. ZDNET notes that Oura re‑engineered the hardware with more powerful LEDs and a new battery, plus algorithm refinements, to reach that longer runtime in a smaller shell. For users who constantly bump their ring into hard surfaces, the stronger finish and slight battery bump are meaningful quality‑of‑life upgrades.
Health Features and Passive Blood Pressure Tracking
Both Oura Ring 4 and Oura Ring 5 focus on detailed wearable health monitoring, including sleep analysis, recovery indicators, and continuous activity insights. The core tracking experience remains similar, so Ring 5 is more of an evolution than a revolution. The standout new health capability on Oura Ring 5 is passive blood pressure tracking, which expands the ring’s role beyond sleep and readiness into cardiovascular awareness. This feature adds another layer to its health picture without demanding more effort from the wearer, keeping the experience as passive as possible. While Oura has not turned Ring 5 into a full medical device, this extra blood pressure tracking signal can help users spot trends and correlate blood pressure changes with stress, recovery, or lifestyle shifts. For health‑focused buyers, that additional data point may be the most compelling reason to skip Ring 4 and go straight to Ring 5.
Should Oura Ring 4 Owners Upgrade to Ring 5?
For most people, the Oura Ring 5 upgrade question comes down to priorities. If your Ring 4 still works well, you are happy with its fit, and you do not feel limited by its durability or battery life, the differences may feel incremental rather than essential. Both rings deliver strong, day‑to‑day health tracking with similar insights. However, if you find Ring 4 bulky, if its finish is badly scratched from daily use, or if you are excited about passive blood pressure tracking, Ring 5 becomes far more appealing. It is smaller, lighter, more durable, and slightly longer‑lasting on a charge, while preserving Oura’s familiar app experience. New buyers choosing their first smart ring will likely find Ring 5 the better long‑term bet. Existing Ring 4 owners should weigh comfortable wear and the value of extra health data before deciding to upgrade.
