Indian tech company Noise has officially unveiled the Luna Ring Gen 2, its second-generation smart ring that offers AI smarts and industry-leading battery life.
After launching the first generation ring in 2023, Gen 2 has appeared at CES 2025, hoping it can take a bite out of sales of the Oura Ring and the many other rings that have emerged since Oura’s success.
Like the original, the Gen 2 is made of titanium, which is pretty much the finish of choice for most smart rings. It has a sensor array that can track metrics including heart rate, stress, blood oxygen levels, and of course monitors your sleep time and daily movements.

In terms of those new AI powers, Noise states that it will use your health and wellness data to boost workout and nutrition advice to make using the ring a more personalized experience. Noise isn’t alone in using AI to add news features: the Evie Ring adds an AI-powered health assistant to its smart ring for women.
The new AI features will be free to access, just like the rest of the Luna Ring Gen 2 features, and will once again be an option for both iPhone and Android phone users.
In addition to this new AI smarts, Noise is also going big on the battery front, promising up to 30 days of battery life on the Ring Gen 2. The original Luna Ring delivered up to 7 days of battery life, so that’s quite a jump. That means it will offer longer battery life than the Oura Ring 4 (7-8 days), Samsung Galaxy Ring (7 days) and the current battery champion the RingConn Gen 2 (10-12 days).
Pre-orders for the Luna Ring Gen 2 start on January 9, 2025, with shipping scheduled for March 2025. Noise told us that the Luna Ring Gen 2 will be available online for the US and UK and in the first week in the retail will be launched. half of 2025.
While we’re still not convinced by the early attempts to combine AI and smart rings, we can definitely get on board with a smart ring that lasts a month.
