Samsung Galaxy Ring

The lightest ring, best inside Samsung’s ecosystem.

Comfort, resting heart rate and Samsung Energy Score

Sleep scoring is inconsistent, and iPhone loses most features

Vora reads Galaxy Ring data through Samsung Health for a fuller picture.

Solid for resting HR and HRV trends but finger PPG trails Oura on sleep staging per an independent one-week head-to-head, and struggles to track rapid heart-rate swings during workouts.

HotHardware, wearing the ring alongside a OnePlus Watch 2, Galaxy Watch Ultra and Pixel Watch 3 for several days and nights, found the ring's data matched the smartwatch data to within about +/-10 percent across metrics; the sleep-vs-Oura gap is documented separately by Android Authority.

Delivers the core ring set (sleep, HR, HRV, SpO2, skin temperature, cycle, Energy Score) but reviewers call it thin, with no GPS, no ECG and blood-oxygen readings that vary with finger placement.

Engadget rated it 80/100, called it fairly basic at the moment, and noted blood oxygen levels varied wildly depending on which finger the ring was worn on; the ring's spec sheet confirms it has no ECG or GPS. Engadget ↗

Tests a genuine week when new, but owner reports document steep degradation, which drops its long-term reliability below the spec-sheet promise.

A one-year long-term review reported battery falling from about 7 days when new to roughly 5 days at 6 months and about 2 days after a year, a pattern corroborated by Android Authority's battery-drain report and multiple Samsung community and Reddit owner posts. TechGuySmartBuy one-year review ↗

One of its strongest points: it is among the lightest smart rings and reviewers repeatedly forget they are wearing it, including while sleeping.

Engadget said the ring, about 2.3 grams (the Grade 5 titanium ring is 2.3 to 3.0 grams by size per Samsung specs), is so light the reviewer barely feels it on their finger when trying to fall asleep. Engadget ↗

Excellent inside Samsung's world but full features need a Galaxy phone, and it does not work with iPhone at all, which limits it for an iOS-first coaching app.

Engadget notes the ring does not work with iPhones and that Energy Score, sleep tracking and Wellness Tips are based on Galaxy AI, requiring a Galaxy phone, the Samsung Health app and a Samsung account. Engadget ↗

The no-subscription model is a real advantage over Oura, and it now street-prices near $299, though a documented year-one battery cliff dents its long-term worth.

9to5Google reports the Galaxy Ring is regularly $299 in all colors and sizes in 2026, $100 off the $399 list price, and that Samsung charges no post-purchase subscription unlike rivals such as Oura. 9to5Google ↗
