What This Oura Ring 5 Upgrade Debate Is Really About
The Oura Ring 5 vs Ring 4 upgrade question is about whether a slimmer, more durable smart ring with added wearable health features like passive blood pressure tracking and slightly better battery life is worth paying more for and accepting ongoing subscription costs, compared with keeping the still capable and accurate Oura Ring 4 you already own. Oura Ring 5 shrinks the titanium body by about 40% compared with Ring 4, aiming to feel closer to a regular wedding band than a chunky gadget. It also extends advertised battery life from five to eight days on Ring 4 to six to nine days on Ring 5 while keeping the familiar app experience. The real decision is whether comfort, subtle design, and new health metrics matter more to you than saving money and sticking with a proven device.
Design, Comfort, and Durability: The Biggest Everyday Changes
For most people, the main Oura Ring 5 upgrade will be how it feels and looks. Oura has redesigned the ring to be 40% smaller than the Oura Ring 4, measuring about 6.09mm wide and 2.28mm thick, which brings it much closer to the profile of a standard band. Reviewers note that the older Ring 4 can feel chunky, especially on smaller hands, and can grind against nearby fingers or feel intrusive during sleep and workouts. By shrinking the body without sacrificing battery life, Oura Ring 5 aims to disappear on your finger instead of standing out as tech. The titanium body is also described as more scratch-resistant and carries an IP68 rating with water resistance up to 100 meters, a meaningful upgrade if you often knock your ring against hard surfaces or keep it on in the pool or shower.
Health Features and Blood Pressure Tracking: What Actually Changes
Both smart rings deliver the core wearable health features many buyers care about: continuous heart rate, heart rate variability, temperature trends, sleep tracking, and activity data fed into the familiar Oura app. The Oura Ring 5 adds one headline feature: new passive blood pressure tracking, which runs in the background rather than requiring manual readings. This can strengthen its role as a health companion, particularly if you monitor cardiovascular trends. However, this blood pressure tracking sits behind a paid subscription tier, which sparks debate over value. You are no longer deciding only between two bits of hardware; you are choosing a hardware-plus-software bundle where some of the most advanced metrics cost more over time. If you do not care much about blood pressure trends and are satisfied with Ring 4’s sleep and readiness insights, the wearable health upgrade may feel smaller than the marketing suggests.
Battery Life, Charging, and Subscription Costs
On paper, Oura Ring 5 improves battery life by about a day. The Ring 4 is rated for roughly five to eight days, while the Ring 5 is rated for six to nine days depending on use. That extra buffer matters if you dislike frequent charging or rely on overnight data every day. A new portable charging case, highlighted alongside the Ring 5, can keep the device charged for up to 30 days, which is handy for travel. Alongside hardware, though, you must factor in the subscription model. Access to full insights and advanced features, including the new blood pressure tracking, requires a paid plan, and many buyers feel they are paying twice: once for the ring and then again every month. If you already own a Ring 4, think about how much you use subscription features now before deciding that a slightly longer battery and new case justify upgrading.
Should You Upgrade or Keep Your Oura Ring 4?
Choosing an Oura Ring 5 upgrade comes down to priorities rather than raw performance. The Ring 4 remains a solid smart ring for sleep and recovery, and its tracking is still competitive for most people. Upgrade if you care about a thinner, more discreet ring that blends with other jewelry, want better durability and scratch resistance, and see clear value in passive blood pressure tracking within a paid subscription. Stay with Ring 4 if you are happy with current comfort and data, prefer to avoid a higher device price, or do not plan to pay for advanced software features. In short, Oura Ring 5 is the better smart ring on paper, but the smartest move is to upgrade only if its design gains and new health metric align with how you already use your wearable.
