Samsung’s Wearables Are Getting Solid-State Batteries Soon
Samsung is planning to introduce a new battery technology for its wearable devices, including the Galaxy Watch and Galaxy Ring. According to a report from 9to5Google, the company will adopt all-solid-state batteries to enhance energy density in its upcoming Galaxy Ring 2 or Galaxy Ring 3.
How Solid-State Batteries Differ from Lithium-Ion
Currently, wearables use lithium-ion batteries, the same type found in smartphones and many other gadgets. These traditional batteries rely on liquid electrolytes, whereas solid-state batteries use a solid electrolyte instead.
This shift brings several advantages:
Samsung’s Progress and Expected Launch
In January 2025, Samsung Electro-Mechanics CEO Chang Dukhyun confirmed that the company’s all-solid-state batteries, also known as ASSBs, are ready and have achieved the highest energy density and capacity-to-size ratio in the industry.
The first Samsung device to feature this new battery technology is expected to be the upcomingGalaxy Ring. According to the report, Samsung’s first solid-state battery-powered product could launch in the fourth quarter of this year.

It could be the Galaxy Ring 2 or Galaxy Ring 3, depending on the release timeline of the Galaxy Ring 2, which may arrive in July alongside theGalaxy Z Fold 7 and Flip 7.
Silicon-Carbon vs. Solid-State Batteries
Recent flagship phones like the OnePlus 13 and Xiaomi 15 usesilicon-carbon batteries. These improve traditional lithium-ion batteries by enhancing the anode with silicon, boosting energy density while still using liquid electrolytes. We expectthis technology to be used in the upcoming Galaxy S26as well.
Solid-state batteries, on the other hand, represent a more fundamental shift, replacing the liquid electrolyte with a solid one. This change enables the use of lithium metal anodes, increasing its energy density and safety, and potentially also allowing for faster charging.

However, note that silicon-carbon batteries are still denser than solid-state batteries.
