Experts like it for Samsung phone owners: subscription-free, comfortable, with a charging case. Tom's Guide calls it the best for sleep tracking. But nearly half of its Amazon ratings are 1 or 2 stars, mostly about batteries that stop holding a charge or rings that die. Tom's Guide also warns that Oura's patent case could pull it from sale or end support.
Subscription: None (WIRED, PCMag)
Top complaints
- Battery stops holding a charge; rings die
Amazon's review summary says the battery stops holding a charge (some charge twice a day) and that many units die within a year. In 2025, 9to5Google reported a Galaxy Ring whose swollen battery got stuck on a user's finger; Samsung called such cases 'extremely rare'.
- Best only with a Samsung phone
It's Android-only, and the Energy Score and wellness tips rely on Galaxy AI on a Samsung phone (WIRED). PCMag lists limitations with non-Samsung phones.
- Accuracy and legal uncertainty
PCMag saw some accuracy issues, and WIRED found sleep tracking 'a bit too generous', noting it lacks a gyroscope. Tom's Guide says Samsung's patent dispute with Oura could lead to removal from sale or end of support.
What owners love
- Detailed sleep tracking with no fee
Tom's Guide names it the best ring for sleep tracking, with data on movement, breathing, temperature, heart rate and blood oxygen, and no membership.
Source: Tom's Guide (best smart rings) - Light and comfortable
PCMag and Tom's Guide call it lightweight and comfortable; WIRED says it's slimmer and lighter than the Oura Ring 4.
- Charging case and good accuracy in some tests
The case holds an extra charge or two (PCMag, Tom's Guide). WIRED's former editor found accuracy similar to the Apple Watch Ultra, including automatic workout detection.
- You use an iPhone
- You don't have a Samsung phone
- You want long-term support certainty while the patent case continues
- Samsung Galaxy phone and Galaxy Watch owners
- No monthly fee
- A charging case for travel
