Samsung is reportedly preparing a discreet but significant change in its upcoming batteries. A new technology could increase battery life while avoiding the flaws that appeared on older models. All without sacrificing charging speed.
Battery life remains a key concern for smartphone users. While screens are getting brighter, processors are more powerful, and cameras are more sophisticated, batteries haven't seen the same progress. At Samsung, high-end models are regularly criticized for their limited endurance and, in some cases, for problems with batteries swelling after several months of use. A defect that can lead to malfunctions or even deformation of the device.
To address these criticisms, Samsung is reportedly planning to adopt a new technology called SUS CAN. According to a report from Korean media outlet TheElec relayed by SamMobile, this battery designed with a stainless steel casing would solve several problems at once. It would offer a better energy density, allowing for increased capacity without making it larger. It would also accelerate charging speeds, while avoiding the bloat seen on some previous generations. Apple is already using this technology on the iPhone 16 Pro Max.

Using stainless steel instead of aluminum makes the battery more robust and more stable over the long term. It is more resistant to corrosion and allows for better repairability. This has been an important point since the entry into force of new European regulations that impose greater ease of replacement. Although steel dissipates heat less well, Samsung is reportedly prioritizing durability and regulatory compliance here, without sacrificing performance.
It is not yet known when this technology will be integrated into Galaxy models. Some hope it will debut with the Galaxy S26 or the Galaxy S26 Ultra, expected in early 2026. A rumor already suggests a 5,500 mAh battery for this version. If this is confirmed, Samsung could finally offer a concrete advance in an area long considered to be lagging behind its Chinese competitors, who are more aggressive in innovating in terms of autonomy.
