According to reports, Samsung is gearing up for a major enhancement in its smartphone battery technology, which could be on the horizon sooner than anticipated. The tech giant is reportedly considering a transition from the previously speculated silicon-carbon batteries to a new substance referred to as “SUS CAN.” Although the name might raise eyebrows, this stainless steel-derived advancement has the potential to significantly boost battery life, charging efficiency, and overall device durability in future Galaxy phones—possibly debuting with the Galaxy S26 series.
SUS CAN is a stainless steel composite currently under development by Samsung SDI, the parent company’s battery production unit. The acronym “SUS” conventionally signifies stainless steel within industrial applications, while “CAN” likely refers to the canister-like shape utilized in battery cells. This innovative material is engineered to improve energy density and thermal management within batteries, allowing for larger capacities without increasing physical dimensions.
In straightforward terms, SUS CAN could enable Samsung to fit more power into the same footprint, resulting in longer battery life and potentially expedited charging. This change would be especially welcomed by users who have experienced relatively stagnant battery performance since the Galaxy S10 generation.
Rumblings indicate that the Galaxy S26 series, anticipated to launch in 2025, might be the first to incorporate this upgraded battery technology. If this is accurate, it would represent a significant advancement for Samsung’s flagship offerings, which have been criticized for lagging in battery innovation compared to competitors.
For reference, Samsung’s Ultra models have been limited to 45W charging speeds over the past three generations. In contrast, competitors like Xiaomi and OnePlus have surpassed 100W charging capabilities. With SUS CAN, Samsung might finally bridge that gap, providing faster charging and extended battery life in one package.
Earlier this year, it was reported that Samsung was looking into silicon-carbon batteries, known for their high energy density and rapid charging abilities. This technology has already been utilized in devices such as the Honor Magic 7 Pro, showcasing promising results.
However, it now seems that Samsung might be shifting gears towards SUS CAN. While the precise reasons for this change are unclear, SUS CAN may offer advantages in scalability, cost-effectiveness, or alignment with Samsung’s existing production methods. Additionally, it’s worth mentioning that Apple’s upcoming iPhone 16 Pro Max is rumored to implement similar stainless steel battery technology, hinting at a broader trend within the industry.
If you’re considering an upgrade in 2025, the Galaxy S26 could be worth your wait. With the possible integration of SUS CAN battery technology, Samsung might finally provide the battery performance users have been desiring—longer life, quicker charging, and improved durability.
While nothing has been officially validated, the move towards SUS CAN indicates that Samsung is earnest about tackling one of the most persistent challenges in contemporary smartphones. Whether you’re a heavy user, a mobile gamer, or just someone who’s weary of lugging around a charger, this could be the upgrade that truly matters.
Battery technology has long served as a limiting factor in smartphone advancements. With the rumored transition to SUS CAN, Samsung may be on the cusp of overcoming that hurdle. While we’ll have to wait for official announcements—likely in early 2025—the future of Galaxy phones appears to be significantly more robust, and considerably less “sus.”
