I've tested dozens of smart rings, and most claim to have batteries that last about a week, but make it to day five or six before dying on me. Part of the appeal of smart rings, compared to smartwatches, is supposed to be their longer battery life, so what gives?

I've got one for you if you want a smart ring with a truly competitive battery life. I've been testing the RingConn Gen 2 smart ring that boasts 10 to 12 days — significantly more than some of the most popular rings on the market. In addition, it comes with other perks — and a few drawbacks — that set it apart.
Right off the bat, the RingConn 2 has some green flags. Unlike competing smart ring brands with products that start at $350 and go all the way up to $400 or $450, this smart ring costs $300 — and has no subscription gatekeeping your health data. Sizing starts at six and goes through size 14, and you can get the ring in three colors: silver, black, and gold.
The build of the ring is more square than circular, but I found myself unbothered by this unique shape. It fits comfortably around my finger with no problems. Despite healthy and frequent wear, the ring doesn't tarnish easily, either.

The RingConn Gen 2 comes with a case that extends its already impressively long battery life, powering the smart ring's empty battery for over 150+ days. As someone who is constantly charging several wearable devices at a time, this long-lasting charging case you can use untethered from an outlet is a huge plus.
The RingConn Gen 2 measures your vitals, sleep, activity, and stress, but doesn't measure readiness — a common metric most health tracks include these days. Instead, it provides a Wellness Balance feature. It takes all of your data and displays it in a flower-like graph, with longer petals for the biometrics that are meeting or exceeding the recommended benchmarks and shorter petals for those that aren't.
When all your petals are the same length, it indicates that your wellness is at equilibrium. It's a creative approach, and I liked that I could see all the important data displayed in such a digestible and visual manner right as I opened the app.

Hardcore trainers use the readiness or energy feature on their smart ring apps to gauge how intense their exercise regimen should be for the day. If that's you, you might be displeased with the Wellness Balance functionality, and I'd recommend the Oura Ring, Ultrahuman Ring, or Galaxy Ring instead.
The app also delivers scores alongside context, which is helpful. I was ill one day while testing the ring and spent the entire day sleeping. Because of all the time I spent in bed, it warned me that too much sleep can slow down my metabolism or lead to weight gain.

RingConn says that the battery on its second-generation ring lasts up to 10 to 12 days, but in my testing, I found that it only lasted seven. Still, that's far longer than the battery lives of other smart rings I've tried, which last four to five days on a single charge. I can say without a doubt that this smart ring has the most impressive battery life out of every brand I've tried.
According to its website, the RingConn Gen 2 also boasts a sleep apnea detection feature with 90.7% accuracy. If you're a chronic snorer looking to learn more about how your breathing impacts you throughout the night, the sleep apnea feature could help monitor your condition.
It tells you when there are significant or minor outliers in your sleep throughout the night, providing not only a graph detailing this but also a timeline showing when your SpO2 fluctuated during the night.
I wore the Oura Ring 4 in tandem with the RingConn Gen 2 and found that the latter seems to underestimate both the time I spend asleep and the steps I take throughout the day.

On a healthy night of sleep, Oura recorded eight hours and two minutes, a sleep efficiency of 94%, and a sleep score of 90. RingConn recorded an 84 sleep score, seven hours and 45 minutes asleep, and a sleep efficiency of 91%. In both cases, RingConn is subtracting around 15 minutes from my night's sleep.
The one area where I feel RingConn's smart ring is lacking is its user interface. The app feels underdeveloped, and some of the messages lacked personal context that proved they were being generated from my own data. On one good sleep score day, all that it said when I clicked on the sleep tab was: “Good sleep makes you happy.” I hope the recommendations can become more tailored and informative in future updates.
ZDNET's buying advice
I enjoyed most aspects of wearing this subscription-free smart ring, and at $300, it's one I'd recommend to those looking for an alternative to Oura's subscription-based services. Especially if you want battery life that will last you a week.
The user interface is a little under-developed, and some of the health insights seem a little impersonal. But otherwise, the RingConn Gen 2 is an impressive smart ring with on the cheaper end of the spectrum.
