Samsung's Galaxy watches could see a significant increase in battery life thanks to solid-state technology.
The industry refers to it as a 'dream battery'.
Samsung is conducting tests on a new battery technology for its wearable devices, which could provide its Galaxy Watch and Galaxy Ring models with battery life superior to that of the competition. According to reports, the company has developed "the world's first ultra-small solid-state battery for wearables," known as the "dream battery."
It is detailed that Samsung Electro-Mechanics has manufactured a solid-state battery with an energy density of 200Wh/L, the highest in the industry. This increased density implies greater capacity, translating into longer battery life for daily use and physical activity tracking.
Currently, Samsung is evaluating this battery alongside corporate clients, with the possibility of starting mass production in the first half of 2026. The first wearables to benefit from this technology include the Galaxy Ring, Galaxy Watch, and Galaxy Buds.
The incorporation of solid-state battery technology represents a significant shift in the wearable devices industry. However, Samsung is not the only company interested in this innovation. This year, an Apple supplier, TDK, also announced an advancement in this technology, promising battery capacities up to 100 times greater than the current ones.
In addition to the benefits in capacity and lifespan, solid-state batteries charge much faster than traditional ones and offer greater flexibility in design, allowing their use in various devices of different shapes and sizes, including the Galaxy Ring and leading market smartwatches.
Given that many current smartwatches, such as the Apple Watch Series 10 and the Galaxy Watch 7, often struggle to last over 24 hours of use, the need for more reliable and durable devices will increase as reliance on these products for health and wellness monitoring becomes commonplace. The company that first commercializes solid-state batteries for wearable devices, whether Samsung, Apple, or another entity, will gain a significant competitive advantage.
