Oura Ring 3 vs Oura Ring 4: Comparing Features & Benefits in 2025

Choosing Between the Oura Ring 3 and Oura Ring 4: A Comprehensive Guide

The Oura Ring continues to revolutionize how we monitor sleep, activity, and stress, with its latest iteration turning heads in the wearable tech market. The release of the Oura Ring 4 has brought significant updates, enticing potential buyers, especially with its improved comfort and technology.

Significant Improvements with Oura Ring 4

One of the most talked-about upgrades in the Oura Ring 4 is its sophisticated sensing technology. The latest version boasts 18 signal pathways, surpassing the 8 pathways of the Oura Ring 3. This advancement provides users with detailed and precise health data. Importantly, the sensors are strategically receded, significantly enhancing comfort by avoiding the uncomfortable pressure points that some users experienced with the Oura Ring 3. The sleeker and lighter design of the Oura Ring 4 makes it more appealing, particularly to those sensitive to bulkier wearables.

Expanded Size Range

An additional physical enhancement in the Oura Ring 4 is the expanded size range, offering sizes four through fifteen compared to the Oura Ring 3’s sizes six through thirteen. This upgrade ensures more users can find a perfect fit, which is an essential factor in comfort and functionality for wearable technology.

Battery Life and Charging

For those prioritizing battery longevity in their wearable devices, the Oura Ring 4 offers an improved experience with a maximum battery life of eight days, although practical use provides around five and a half days. Comparatively, the Oura Ring 3 offers up to seven days of usage, realistically providing around four days between charges. While both models have quick charging times of 20 to 80 minutes, the increased battery longevity of the Oura Ring 4 can be a deciding factor for users who prefer less frequent charging.

Software Updates and Price Considerations

Although the Oura Ring 4 introduces new software capabilities, many are available on the Oura Ring 3, too. Features like automatic heart rate monitoring, revamped stress features, and interactive Oura Lab options enhance user engagement across both devices. The Oura Ring 3, currently available at discounted rates due to the launch of its successor, offers a budget-friendly option for those less concerned about minor ergonomic improvements or battery advancements.

When to Opt for the Oura Ring 3

If budget constraints are a concern, the Oura Ring 3 is a prudent choice. Often offered at significant discounts, it provides comprehensive access to essential features without the higher price tag of the newer model. Furthermore, users content with the existing ergonomics or who can overlook minor discomfort, might find the Oura Ring 3 to be an excellent fit both financially and functionally.

Exploring Alternatives

While Oura rings are a leading choice in the smart ring market, alternatives may better suit specific user needs. The Samsung Galaxy Ring offers seamless integration with Android devices and extended battery performance, whereas the Ultrahuman Ring Air stands out for users who prefer a subscription-free model compatible with both Android and iOS devices.

Ultimately, the selection between Oura Ring 3 and Oura Ring 4 hinges on personal priorities—whether it's cutting-edge technology, enhanced comfort, affordability, or technical specificity. Each ring provides robust capabilities for what they were designed for, keeping you informed and on top of your health metrics.
