What Sets Oura Ring 5 Apart from Ring 4?
Oura Ring 5 vs Ring 4 is a head‑to‑head smart ring upgrade comparison between two generations that focus on sleep, readiness, and all‑day health tracking, asking whether a slimmer design and new durability and wellness tools justify replacing an older device. The fifth‑generation Oura Ring is a complete redesign that shrinks the band while preserving the core health tracking comparison points such as sleep staging, heart rate, and readiness scores. It is 40% smaller than Oura Ring 4 and aims to feel more like jewelry than a gadget on your finger. According to ZDNET, Oura Ring 5 “is its smallest yet,” signaling a shift toward subtle wearability. For existing Ring 4 owners, the core experience will feel familiar, so the decision rests on comfort, aesthetics, passive blood pressure tracking, and whether these refinements are worth the higher upfront cost.
Design, Comfort, and Battery Life
The most obvious difference in the Oura Ring 5 vs Ring 4 matchup is size and feel. Oura Ring 5 measures 6.09mm wide and 2.28mm thick, compared with the Ring 4’s 7.99mm width and 2.88mm thickness, making the newer model significantly slimmer and lighter on the finger. Android Authority notes that the 40% smaller build makes the ring less noticeable during sleep, workouts, and daily tasks, which is vital for a screenless tracker meant to disappear into your routine. Battery life also gets a small bump: Oura Ring 5 is rated for six to nine days per charge, while Ring 4 typically lasts five to eight days. Oura says it achieved this by re‑engineering the battery and refining algorithms without sacrificing performance, so you gain comfort and slightly longer wear between charges.
Durability and Materials Upgrades
Durability is another key smart ring upgrade in Oura Ring 5 vs Ring 4. Both rings use titanium, but the newer model adds a scratch‑resistant vapor deposition coating that Oura calls its most scratch‑resistant finish yet. It also moves to an IP68 rating, signaling stronger protection against dust and water exposure than the previous generation. For users who knock their ring on gym equipment, countertops, or doorframes, this matters. Android Authority highlights that metallic Ring 4 models can show heavy wear over time, while more durable finishes stay cleaner; Ring 5’s improved coating aims to narrow that gap so your smart ring looks closer to jewelry for longer. Color options also expand with a refreshed Gold shade and a new Deep Rose, so style‑conscious users can match their ring more closely to their personal aesthetic.
Health Tracking Comparison and New Blood Pressure Features
From a health tracking comparison standpoint, Oura Ring 5 keeps the same core strengths as Ring 4: detailed sleep analysis, overnight heart rate, readiness scores, and daily activity insights. ZDNET notes that Oura even added more powerful LEDs and tuned algorithms in Ring 5 for efficient biometric measurements, all while maintaining or improving battery life. The headline health upgrade, however, is passive blood pressure tracking, which appears as a new capability in Oura Ring 5. This feature works in the background, complementing the rest of Oura’s wellness metrics without requiring constant user interaction. The result is a more complete picture of cardiovascular health trends over time. Still, for many users the day‑to‑day tracking experience between generations will feel very close, so the benefit of blood pressure tracking needs to be weighed against your upgrade budget.
Should Oura Ring 4 Owners Upgrade?
Whether to pursue a smart ring upgrade comes down to priorities. Oura Ring 5 starts at USD 399 (approx. RM1,880), compared with Oura Ring 4 at USD 349 (approx. RM1,645), so you pay more for the slimmer build, durability boost, longer battery life, and passive blood pressure tracking. If your Ring 4 feels bulky, looks heavily scratched, or its battery is fading, the redesign alone may be worth the jump. If you care about a ring that blends in like a wedding band, the 40% smaller profile is a strong incentive. On the other hand, if you are satisfied with your current fit, do not need blood pressure insights, and your Ring 4 still performs reliably, staying put remains a sound choice. New buyers, though, get the most balanced package by stepping straight into Oura Ring 5.
