Samsung’s Galaxy Ring Works Best Beside a Galaxy Phone

The ring pairs through Galaxy Wearable, which needs Android 11 or later, and the quick start guide says a Samsung account is required. There's no iPhone app. Samsung's product page goes a step further and says the account must be registered on your Samsung Galaxy smartphone.

The basics run through the free Samsung Health app: sleep with snore detection, heart rate, skin temperature at night and cycle tracking. Two features are tied to newer Samsung hardware. Energy Score, the morning readiness number, and Wellness Tips both need a compatible Samsung Galaxy AI phone. So does the double pinch that takes a photo or dismisses an alarm, which Samsung lists under its Galaxy devices.

Samsung's footnotes set three kinds of condition: a compatible phone, the Samsung Health app and a Samsung account. A monthly fee isn't one of them, and that's the clearest difference from Oura's membership model. Auto workout detection covers walking and running only, so a bike ride or a weights session has to be started by hand in Samsung Health.

Samsung's page promises a seven-day charge, and up to 14 days away from an outlet once you count a full charging case. The footnote limits the seven days to sizes 12 and 13. Every smaller size is rated for up to six. Samsung has since added two sizes to its sizing kit, and the footnote doesn't say where they fall.

The case charges the ring first and then itself, according to the quick start guide. Each ring size has its own case model, so a spare or replacement case has to match your size. Samsung's support replies on its store say the ring keeps its sensors running when it's off your finger and out of the case, so put it back in the case when you take it off. They also say wearing a Galaxy Watch alongside it stretches the ring's battery, because the two stop duplicating some tracking.

The longer question is the battery's life in years. Owner reviews on Samsung's store include a run describing battery life falling sharply within the first year or so, and Samsung's replies point to a one-year limited warranty. Samsung Care+ is sold as an add-on for longer cover.

The quick start guide in the box rates the ring IP68: dust-tight, and tested for submersion in up to 5 feet of fresh water for 30 minutes. Samsung's web page adds a 10ATM classification. It defines that as water down to 100 m for 10 minutes. The same page puts the IP68 depth at 6 feet, again for 30 minutes.

That gives one IP68 rating two depths, and only the web page mentions 10ATM. Plan on the guide's version, the narrower of the two. Its test used fresh water, so laps in a chlorinated pool or a day in the sea go beyond what it describes. Samsung's page asks you to rinse off residue and dry the ring after it gets wet.

The guide also rules out an ultrasonic cleaner, which it says can permanently damage the ring.

Samsung and Best Buy both sell the ring size-first: a kit of sample rings arrives before the ring itself. Samsung asks you to wear a sample for at least 24 hours before you confirm the size.

Wear it with the raised orientation mark facing your palm, on a finger where it is neither tight nor loose, the quick start guide says. It also warns against wearing another ring right next to it, since the two can scratch each other. The titanium comes in matte black, matte silver and a glossy gold, and Samsung says the concave outer face helps it resist scratches.
