Samsung is testing a new battery technology for its wearable devices that could give its Galaxy Watch and Galaxy Ring models the best battery life on the market.
The maker of the Samsung Galaxy Watch 7, Samsung Galaxy Watch Ultra and the new Samsung Galaxy Ring has reportedly developed “the world’s first ultra-small, all-solid-state battery for wearable devices.” This is evident from a report by Business Koreastating that the technology is called a ‘dream battery’.
The news states that Samsung Electro-Mechanics has created a fully solid-state battery for wearables with an energy density of 200 Wh/L, the highest in the industry.
Higher density means higher capacity, which in turn means longer battery life for everyday use, fitness tracking and more. BK reports that Samsung is currently evaluating its battery with business customers, and it could begin mass production in the first half of 2026. Specifically, the report names the Galaxy Ring, Galaxy Watch and Galaxy Buzz as the first wearable devices expected to be adopted. advantage.
Samsung’s solid-state unveiling
The introduction of solid-state battery technology to Samsung’s wearables would be a real shake-up for the wearables industry, but it’s not the only company with the prize in its sights.
Earlier this year, Apple supplier TDK reported its own breakthrough in the technology, which it said could offer battery capacity about 100 times greater than existing technologies.
While the benefits in terms of capacity and battery life are obvious, there are other obvious bonuses. Solid state batteries charge much faster than traditional batteries, and are more flexible in design so they can be applied to a wide variety of technologies of all shapes and sizes – hence the aforementioned application in devices like the Galaxy Ring as well as the best smart watches.
As it stands, your average smartwatch (like the Apple Watch Series 10 or Galaxy Watch 7) will struggle to get through 24 hours of use unless you’re using one of the best Garmin watches on the market. As we become more dependent on wearable devices for our health and well-being, including essential protection against heart disease and sleep apnea, the need for more reliable and durable devices will grow exponentially. The first company to crack portable solid-state batteries, whether it’s Samsung, Apple or someone else, will certainly have a huge advantage.
