Samsung sdi races to 2027: solid-state batteries poised to rewrite smartphone battery life

Samsung SDI is poised to revolutionize mobile power with the imminent mass production of all-solid-state batteries by late 2027, a development that could finally deliver the ‘dream’ battery consumers have long demanded.

A decade in the making: samsung’s long road to solid-state

After teasing the technology back in 2017—a promise of ‘dream’ batteries in future Galaxy devices—Samsung SDI has spent nearly a decade relentlessly pursuing solid-state innovation. Initial fanfare in 2019 failed to materialize, but recent signals indicate a dramatic shift in momentum. Internal demonstrations for key automotive and robotics clients have reportedly generated strong interest, fueling a renewed sense of urgency within the company.

“We’re seeing real, tangible progress,” explained Vice President and Head of Samsung SDI’s all-solid-state battery production development group, Kim Eun-ha, recently. “The response has been overwhelmingly positive, particularly regarding the targeted mass production date.”

Beyond lithium-ion: the advantages of ‘dream’ batteries

Solid-state batteries offer a suite of compelling advantages over traditional lithium-ion technology. The most significant is a dramatically increased energy density, allowing for smaller, lighter batteries packing significantly more power. Furthermore, they promise drastically faster charging times and, crucially, an enhanced level of safety – eliminating the risk of fires and toxic chemical leaks associated with conventional batteries.

While initial production costs remain a challenge—currently ranging from $400 to $600 per kilowatt-hour compared to $81 for lithium-ion—Samsung SDI anticipates competitive pricing through scale and adoption. The company’s pilot manufacturing line, established in 2023, demonstrates a clear commitment to realizing this ambition.

First on the block: the galaxy ring 2

The Galaxy Ring 2 is widely expected to be the first Samsung product to benefit from this technological leap. While the Galaxy S27 series, anticipated for late January/early February 2028, will likely follow, the Ring’s earlier launch timeline positions it as the initial beneficiary of days-long battery life. Don't expect a price drop, however; these ‘dream’ batteries will likely command a premium.

“Samsung is already testing these dream batteries in cars and small electronics,” stated Kim Eun-ha. “We’re confident we can deliver a truly transformative battery experience to consumers.”

A bold prediction

Considering the current trajectory, it’s not unreasonable to anticipate smartphones boasting multi-day battery life within the next two years. It’s a shift that could fundamentally alter the user experience and finally justify the considerable investment in this groundbreaking technology. Let’s be clear: the future of mobile power is solid – and it’s arriving sooner than we think.
