Oura Ring 5 vs Ring 4: What This Upgrade Is Really About
Oura Ring 5 vs Ring 4 compares two generations of titanium smart rings that track sleep, recovery, and daily readiness, with the newer model focusing on a smaller design, expanded health monitoring, and a premium price that forces current owners to weigh comfort and new insights against the cost of upgrading. The fifth‑generation ring is built around one bold claim: it is about 40 percent smaller than its predecessor, while still offering a week‑long battery and upgraded sensors. That shrink in size addresses one of the biggest complaints from long‑term Ring 4 users who find a chunky smart ring awkward for gripping, typing, or lifting weights. At the same time, Oura adds a new Health Radar, improved cardiovascular and breathing tracking, and more live activity features. The question is whether those health gains and better wearability make this smart ring upgrade worth it if you already own Ring 4.
Design and Comfort: 40 Percent Smaller, Same Titanium Strength
The biggest day‑to‑day difference in Oura Ring 5 vs Ring 4 is physical. Oura Ring 5 is roughly 40 percent smaller than Ring 4, with a slimmer band that feels closer to traditional jewelry than a gadget on your finger. PCMag reports it measures about 0.24 inches wide and 0.09 inches thick, compared with the Ring 4’s 0.31 by 0.11 inches. Early hands‑on impressions make the impact clear: users notice the Ring 5 less when gripping heavy objects or pressing fingers together, where Ring 4 could leave a slight gap. Both generations use non‑allergenic titanium and are water‑resistant to significant depths, but Ring 5 focuses on a compact, more durable, scratch‑resistant feel, while Ring 4 offers more size and finish options, including ceramic exteriors. If you wear a smart ring 24/7, that size drop is not cosmetic; it changes whether the device fades into your routine or keeps reminding you it is there.
Health Radar Features and Blood Pressure Signals
Where Oura Ring 5 pulls ahead in health terms is its new sensor package and Health Radar features. According to ŌURA’s launch announcement, the ring introduces live activity tracking, a Health Radar with Blood Pressure Signals, nighttime breathing monitoring, GLP‑1 Insights for people on metabolic medications, and expanded Health Records to combine clinical data with daily biometrics. These upgrades sit on top of Oura’s established strengths in sleep and recovery tracking, and the redesigned sensors are claimed to improve accuracy across different finger types and skin tones. For many buyers, the headline is the blood pressure monitoring ring angle: while the Ring 5 does not replace a clinical cuff, it adds continuous blood pressure signals to your health picture, which Ring 4 lacks. If proactive cardiovascular and respiratory insights matter to you, this is the clearest functional advantage of the newer model, especially as Health Radar rolls out more capabilities over time.
Battery Life, Charging and Daily Wear Trade‑offs
Despite its smaller size, Oura Ring 5 maintains the week‑long battery life Ring 4 owners are used to, and early reviewers report it can even stretch an extra day in ideal conditions. That is notable because the new ring packs more powerful LEDs and additional sensors to feed Health Radar and advanced sleep and breathing analysis. Oura supports both generations with the same app membership model, so ongoing battery expectations and software access are similar. Ring 5 also adds a new optional charging case that can store about a month of battery and supports wireless charging, aimed at travelers or those who dislike frequent plugging in. For current Ring 4 owners, this means battery life alone is not a reason to upgrade; it is a tie. The real battery‑related benefit is convenience: a smaller ring you are more willing to wear nonstop and a charging case that makes top‑ups easier to fit around your routine.
Is the Smart Ring Upgrade Worth It? Pricing and Use‑Case Math
On price, the Oura Ring 5 vs Ring 4 comparison is blunt. Oura Ring 5 starts at USD 399 (approx. RM1,840) for base finishes and USD 499 (approx. RM2,300) for premium finishes, while Oura Ring 4 now sits lower, starting at USD 349 (approx. RM1,610) in select finishes and topping out at USD 399 (approx. RM1,840) for premium or ceramic options. Both require a membership of USD 69.99 (approx. RM325) per year for full app features. For new buyers, paying more for a smaller, more durable titanium ring and Health Radar features can make sense, especially if you care about blood pressure signals, GLP‑1 tracking, or breathing insights. For current Ring 4 owners, the math is tougher: your existing ring already delivers strong sleep, readiness, and activity tracking. Upgrading is worth it if you are bothered by bulk, want the most discreet design possible, or value proactive cardiovascular monitoring enough to pay the premium.
