Samsung is gearing up to make a significant leap in the wearables market with its upcoming Galaxy Ring 2, expected to launch in late 2025. According to South Korean news outlet Money Today SK, the second-generation smart ring will feature solid-state batteries, which offer higher energy density compared to conventional lithium-ion batteries.
Solid-state batteries are seen as a game-changer in energy storage technology, providing increased safety, longer lifespan, and greater durability. Samsung has reportedly already reached an energy density of 200Wh/L, and with the Galaxy Ring 2, the target is to achieve up to 360Wh/L. This leap in battery performance could address one of the biggest challenges in wearables—battery life. It’s worth noting that the first-generation Galaxy Ring offered up to seven days of battery life.
The development of this advanced battery technology is being led by Samsung Electro-Mechanics, a subsidiary of Samsung. The company doesn’t intend to limit this innovation to the Galaxy Ring series; instead, it plans to expand its use across other wearable devices in the coming years. Reports suggest that Galaxy Buds in 2026 and Galaxy Watch models in 2027 may also adopt solid-state batteries.
At CES 2025, Samsung is expected to announce the start of mass production for these batteries. In the long term, the company aims to reach an energy density of 400Wh/L, significantly increasing the amount of energy stored in compact devices—crucial for wearables.
However, such cutting-edge technology doesn’t come without drawbacks. Solid-state batteries are expensive to produce, and analysts believe this could push the price of the Galaxy Ring 2 higher. The first-generation model, released in 2024, was priced around $370, and with the added cost of new battery tech, the next version may come with an even steeper price tag.
In conclusion, the Galaxy Ring 2 could mark a major step forward not just in wearable hardware but also in battery technology. If successful, Samsung's use of solid-state batteries might set a new standard for the future of wearables.
