The Samsung Galaxy Ring 2 could arrive soon with a denser "Dream Battery." And for now, that's probably the best we can hope for to make smart rings longer-lasting. But there's a more fundamental fix — patented by Oura, unsurprisingly — that I think Samsung needs to consider for the Galaxy Ring's future.
According to the report, Samsung is considering using solid electrolytes instead of a traditional lithium-ion battery, increasing the energy density from 200 to 360Wh/L and offering greater flexibility that would be perfect for this rounded form factor.
