RingConn Gen 3 vs Samsung Galaxy Ring

On the finger they’re close. Galaxy Ring is 2.6 millimeters thick and 2.3 to 3.2 grams; RingConn Gen 3 is 2.3 millimeters thick and weighs 2.5 to 3.5 grams. The bigger gaps are in the phone each one needs and how often each one goes back in its case.

Galaxy Ring needs a Galaxy phone

Samsung requires a Samsung account registered on a Samsung Galaxy smartphone, and your health data goes to Samsung Cloud on that account. The ring runs through Samsung Health and Galaxy Wearable, so an iPhone is out, and so is any Android phone Samsung didn’t make.

RingConn Gen 3 runs its own app on any phone with iOS 17.0 or Android 10.0 and up, whoever made it. Your history stays on your RingConn account when you pair a new ring.

Each ring has one trick tied to that choice. On a Galaxy phone, Samsung Galaxy Ring takes a double-pinch gesture for alarms and the camera. Gen 3 has a vibration motor that taps your finger with health alerts and reminders, on any phone.

Battery: RingConn’s shortest rating beats Samsung’s longest

RingConn rates Gen 3 at 10 to 12 days when its vibration motor is active and 11 to 14 when it’s switched off; the “up to 14 days” on its comparison chart is that second figure. Samsung’s longest rating is 7 days.

Samsung gives that figure three ways. Its introductory guide quotes up to 7 days and a full charge in about 80 minutes, using example batteries of 18 milliamp-hours for size 5 and 23.5 for size 13. Its charging guide lists 17 milliamp-hours and up to 6 days for sizes 5 to 7, 18.5 and up to 6 days for sizes 8 to 11, and 22.5 and up to 7 days for sizes 12 to 15, at about 90 minutes to charge. The Galaxy Ring page gives 7 days to sizes 12 and 13 and 6 to smaller sizes, which leaves sizes 14 and 15 with only the charging guide’s 7-day figure.

Charging and storage

RingConn quotes about 120 minutes to fill Gen 3’s case and leaves the ring’s own charging time blank. It’s a universal case that charges other RingConn rings too, and a Gen 2 case works with Gen 3 in a matching size.

Galaxy Ring’s case comes in the box, is sized to your ring, and is the only way to charge it: plug the case into USB-C, set it on a wireless charger, or use Wireless PowerShare. If the ring is completely flat, give it at least ten minutes on the case before expecting a response. A full case can recharge the ring up to 1.6 times, Samsung says, and its marketing stretches that to up to 14 days away from an outlet. That’s spare charge in the case, not days on your finger, so it doesn’t compete with RingConn’s 11 to 14.

If you travel without your phone, Gen 3 holds 10 days of data on the ring; Samsung doesn’t say how much Galaxy Ring keeps.

Alerts and trends against Energy Score

Gen 3 combines its motor with a 3-axis accelerometer, a temperature sensor and an optical heart-rate sensor. All day and night it logs heart rate, HRV and blood oxygen, and it covers steps, calories, workouts and VO2 Max, plus respiratory rate, which RingConn’s FAQ counts as all-day and its comparison chart as nighttime. Sleep tracking covers duration, stages and sleep-apnea risk indicators, which RingConn says aren’t a diagnostic sleep study. Its vascular trends blend nighttime patterns with your habits and manual inputs, and they aren’t blood-pressure numbers. By RingConn’s own account, Gen 3 is not a medical device.

Galaxy Ring’s sensor list is shorter: an accelerometer, an optical heart-rate sensor and skin temperature. Samsung builds sleep analysis from heart rate, blood oxygen and skin temperature, lists snore detection in the US, and turns sleep, activity and heart rate into an Energy Score in Samsung Health, with no separate membership. Once you switch it on, the ring spots walks and runs by itself. Samsung says cycle tracking isn’t for contraception or anyone under 18, and is less useful if hormonal treatment stops ovulation.

Neither ring is a GPS watch, and neither gives you a diagnosis.

Sizes and water

RingConn sells sizes 6 to 15 and you need its Gen 3 kit to size yourself. Galaxy Ring runs 5 to 15, so a size 5 is Samsung’s alone in this pair, and its band is 7 millimeters wide. Samsung’s US weight range tops out at 3.2 grams, yet its UK size-15 listing says 3.3 grams. Samsung’s sizing video shows nine sample rings, sizes 5 to 13, and its sizing article says the kit includes every available size. Samsung suggests wearing a sample for more than 24 hours before you choose.

Both claim 100 meters, but the fine print differs. Samsung rates Galaxy Ring 10 ATM and IP68: 100 meters for up to 10 minutes, IP68 to 6 feet for 30 minutes, and a rinse after salt water or chlorine. RingConn rates Gen 3 IP68 and 10 ATM, to 100 meters or 328 feet, and doesn’t attach a time limit to it.

Price and stock

Gen 3 cost from $349 on 19 September 2026, with RingConn noting that prices differ by region. Galaxy Ring was $399.99; Silver was still available that morning, but by evening Black, Gold and Silver all showed out of stock. The $150 instant trade-in credit on Samsung’s site is a promotion, not the ring’s price, and Samsung had no Galaxy Ring 2 to compare. Check both stores for your size and finish before you buy.
