Samsung is reportedly preparing to launch a significant battery upgrade in its upcoming flagship series, potentially starting with the Galaxy S26, according to a new report from The Elec. The company appears to be moving toward a new battery design known as SUS CAN — a stainless steel-based technology aimed at enhancing energy density, charging speeds, and long-term reliability.
SUS CAN: What Is It?
The SUS CAN technology uses stainless steel to reinforce the internal structure of batteries. This method allows for more energy storage in less space, quicker charging capabilities, and greater protection against issues such as battery swelling, which has affected some older Galaxy models.
Interestingly, Apple’s iPhone 16 Pro Max has already adopted this battery architecture, placing pressure on Samsung to follow suit. By implementing stainless steel-based tech, Samsung could bridge the gap with competitors that have already advanced in battery innovation.
Premium Models First
Due to the complexity and cost involved, the new battery technology is expected to debut in premium devices first. The Galaxy S26 is seen as a likely starting point for this rollout, although Samsung has not officially confirmed any details. This shift could help Samsung compete more directly with rivals like OnePlus, which has already introduced devices with batteries exceeding 6,200mAh capacity.
By comparison, Samsung’s latest Galaxy S25 Edge featured a more conservative battery configuration, drawing criticism from tech enthusiasts who expected higher capacity and faster charging.
Possible Line-Up Changes in 2026
In addition to battery upgrades, rumors suggest a shake-up in Samsung’s product line-up for 2026. The company might eliminate the Galaxy S26 Plus model and instead focus on a potential S26 Edge variant. For context, the current Galaxy S25 series includes four models: the S25, S25 Plus, S25 Ultra, and S25 Edge.
The potential removal of the Plus variant might reflect a strategic pivot toward more specialized form factors, though no official statements have been made by Samsung at this time.
Take Leaks with Caution
While the new battery development sounds promising, Samsung has not confirmed any of the details mentioned in the leak. Tech analysts and consumers are advised to treat these reports with caution until more reliable announcements are made.
