Samsung Galaxy Ring 2 Will Feature A Thinner, Lighter Design With Longer Battery Life

Korean publication ETNews reported that the Samsung Galaxy Ring 2 will come with some core improvements. Specifically, it will be thinner and lighter than its predecessor. That new design will also come with improved battery life that extends the current offering of 7 days to 10 days.

To make those changes, Samsung is looking at “optimizing internal component placement,” according to ETNews’ sources. If that sounds familiar, we’ve seen the Korean company use this design method in several devices over the last 18 months.

The ultra-thin Galaxy S25 Edge included a new mounting system, which allowed components to be placed closer together on the motherboard—alongside a new heat management system and shrunken 200MP camera sensor.

That design process was used again for the Galaxy Z Fold 7, which is significantly thinner than the Galaxy Z Fold 6 (8.9mm vs 12.1mm folded). The difference between the foldable phones is stark and remains the best showcase of how impactful shrinking and rearranging components can be to the final product.

It sounds like Samsung will do precisely that for the Samsung Galaxy Ring 2, which may look very different in comparison to not only its predecessor but also rivals like the Oura Ring.

The Samsung Galaxy Ring 2’s delay is also interesting. The original Galaxy Ring launched with Samsung’s 2024 foldables. The Samsung Galaxy Ring 2’s natural release timeline would be alongside the upcoming Galaxy Z Fold 8 and new Galaxy Z Fold 8 Wide this summer. But that isn’t the case, and the timing of Samsung saying it's working on silicon carbon batteries shouldn’t be ignored.

Samsung Galaxy Ring 2 Could Change Wearables Forever With Silicon Carbon Batteries

In February, during a Galaxy S26 press briefing, the head of Samsung’s smartphone R&D team, Sung-Hoon Moon, confirmed that the company is actively developing silicon carbon batteries for its products (via TechRadar). The reason we haven’t seen it in Galaxy phones yet is because the company is rigorously testing them to ensure they’re safe and stable.

For the unaware, silicon-carbon batteries replace traditional graphite anodes with silicon-carbon composites, allowing for up to 20% higher energy density without the extra size.

But they do come with concerns about increased swelling and shorter overall lifecycles. So far, manufacturers have mitigated this with new flexible coatings that act like tiny shock absorbers, holding the silicon in place as it expands and shrinks so the battery stays stable and lasts much longer. This is likely what Samsung is testing to ensure they’re safe and ready for the big stage. Wether that’s in the Samsung Galaxy Ring 2, the Galaxy S27, or both.

Samsung Under Pressure To Match Rivals On Battery Life

We don’t know when Samsung will debut its first silicon carbon-powered Galaxy product, but there is clear pressure to do so. Rivals from Oppo, Motorola, Honor, Huawei, OnePlus, and Xiaomi are releasing smartphones with 7,050mAh silicon carbon batteries in thin designs. For reference, the Galaxy S26 Ultra has a 5,000mAh lithium-ion power pack.

There is a clear dividing line between these new phones that can last a couple of days versus Apple, Samsung, and Google handsets that last one. Brand loyalty is strong for the dominant smartphone makers, but price and battery life are repeatedly shown to be at the top of smartphone buyer concerns. So, I imagine Samsung is moving as quickly as it can to complete its testing.

The delayed release of the Samsung Galaxy Ring 2 may be a hint that it could come with its own silicon carbon battery, which would explain a three-day battery life increase alongside making the device smaller. Perhaps Samsung tests out the results of its silicon carbon battery testing on one of its less popular wearables (which is also a smart place to deploy denser batteries). The company has a history of gently debuting new technology in one product, such as the Galaxy S25 Edge, before integrating it into the flagship lineup. Or, Samsung is confident in the new technology and the entire Galaxy S27 lineup, which will launch early next year, comes with silicon carbon technology.
