Smartwatches and fitness trackers beta · Oura
Owners wear the Oura Ring 3 for years as a sleep tracker, and some still prefer its battery to the newer Ring 4, though owners are divided on how well that battery ages.
On battery life, owners are divided. On the positive side, one owner says their Ring 3 still runs a week or more per charge after two years, and others say it outlasts the Ring 4 they also own.
Battery life is also where the doubts sit, and owners are divided rather than agreed. One long-term owner found that after about two and a half years they had to charge it every other day, got tired of that, and moved to a Ring 4.
The Oura Ring Gen3 is a titanium smart ring that tracks sleep, heart rate, body temperature and daily activity, and shows the results in a phone app. It is for people who want health tracking without wearing a watch. Oura no longer sells it.

From the maker's spec page, checked October 10, 2026. A blank row means the maker does not state it.
The light sensors on the inside of the ring measure your heart rate day and night, and the red light is used for blood oxygen. The temperature sensors pick up small changes in your skin temperature, which helps with cycle tracking and can show early signs that you may be getting sick. The motion sensor counts steps and notices common workouts on its own. The Oura pages I read did not list battery life, water rating, weight, phone compatibility or warranty for this ring, so those rows are blank.
Pick up to three. You get a page with just those, side by side, on the subjects owners raised.
The ring stays in daily use for years. One owner wore it alongside a smartwatch for nearly four years, and another has had theirs for two. For someone who bought it at a big discount after the Ring 4 came out, the appeal held up: they pointed to independent reviews that found little difference in sleep tracking accuracy between the two generations.
Charging is the routine part, and how much of a chore it becomes is where experiences split. Some owners still go about a week between charges. Others found the gap shrinking over time until charging felt like a regular task, and for one owner that was the reason to upgrade.
The battery is the part owners talk about, and its record is divided. Some Ring 3s are still holding a charge for a week or more after two years, and several owners say theirs does better than the Ring 4 they compare it with. Another wore down to charging every other day after about two and a half years, and that owner dealt with it by buying the newer model.
The long-term evidence is thin. Only a handful of owners described living with the ring over time, and every one of them talked about the battery. None said anything about how the shell, the sensors or the app hold up, so this page can't say how the ring holds up beyond its battery.
Parts named in the 9 accounts that describe a failure

Nothing with a clear majority yet. Owners who raised these subjects were split, or too few to judge.
Nothing has a clear majority against it yet. Counted from the owners who raised each subject, not from everyone. A subject is judged once at least 4 owners raise it.
10 more subjects came up from fewer than 4 owners each, which is not enough for a fair reading. To see how it stacks up, compare it with another machine.
The same owner, asked again at each point. Fills in as owners answer.
Two questions: how long you have had it, and anything you would like to say about it. Then we ask again as it ages. This helps our mission.

Among the 27 owner accounts here that gave a duration, 9 described a failure. Parts named most: battery, battery/charging, unspecified/died.
Before you buy one used, ask the seller: how old it is, whether it was ever repaired and by whom, and whether any of the parts above have been replaced. Ask to see it run. A receipt tells you the warranty start date; most makers honour the term only for the first owner.
