Where reviewers disagree Measured battery life varied by reviewer and ring size — Engadget wrung ~7 days from a size 10, TechRadar only 5.5 days from the same size, with Tom's Guide and Digital Trends landing at 6; none consistently hit Oura's advertised 8 days. Enthusiasm also split: Tom's Guide ('gold standard') and TechRadar ('nearly perfect') were effusive, while Digital Trends called the hardware 'treading water,' leading rivals 'only by a thin margin.'

Battery life (real-world, full charge): 6 days · Step-count deviation vs Apple Watch Series 10: up to 1,000 steps/day
The Oura Ring 4 is hands-down the greatest smart ring for fitness tracking that money can buy.
the step counts are still not as reliable compared to many of the best smartwatches like the Apple Watch Series 10 (my numbers were up to 1,000 steps off depending on the day)
On a full charge, I went six days before needing to charge it before bed, to ensure that it wouldn't die overnight.
Gorgeously designed, easy to wear, long-lasting and full of granular health information, the Oura Ring 4 is nearly the perfect fitness tracker.
the ongoing subscription brings down its prospect as a good-value package
After a week of wear I can see some very light scratching on the surface of my Brushed Silver model
Battery life (size 10, long-term, fairly regularly): 7 days
The Oura Ring 4 is a stellar piece of hardware, an engineering marvel and a useful companion as you go about your day.
It'll often accuse me of doing some form of rigorous workout when, in reality, I'm just going up and down stairs while I get my kids ready for school.
the features held back aren't just nice to have, they're essential
Battery life (size 11, real-world): 6 days · Charge rate: ~50% in ~20 min · Active calories, walking test — Oura 4 vs Apple Watch S10: 162 vs 256 kcal · Avg heart rate, walking test — Oura 4 vs Apple Watch S10: 100 vs 104 bpm · Resting heart rate, sleep — Oura 4 vs RingConn Gen 2: 51 vs 53 bpm
The Oura Ring 4, paired with its excellent companion app, is the best smart ring package available today.
the actual size 11 Oura Ring 4 is looser on my finger than the third-gen ring, and the sizing kit shows the size 10 ring would be much too small.
my Oura Ring 4 has already gathered surface scratches after just a few weeks, and that's without using dumbbells or gripping metal or rocky surfaces.
