Galaxy S26 battery upgrade may improve efficiency without more capacity

The Galaxy S26 series is expected to launch in early 2026, and while big changes might not be on the table, Samsung could be quietly improving battery performance in meaningful ways.

A new report from The Elec claims Samsung is preparing two key battery upgrades. The first is the use of SUS CAN casings, which swap the usual aluminum housing for stainless steel. This material is more durable and better at handling heat, which could help reduce thermal buildup during demanding tasks. Rumors about SUS CAN tech first surfaced in May, and this report suggests Samsung may finally be ready to implement it.

The second upgrade involves using epoxy molding compound (EMC) in the battery protection circuit. EMC reduces electromagnetic interference, which can improve energy efficiency and help the battery deliver more stable power without increasing capacity.

Another rumor, also from May, pointed to Samsung testing silicon carbon batteries. These high-density cells can hold more energy in the same space or match current capacity in a smaller form factor. OPPO has already used silicon carbon in the Find N5, showing that the tech is viable in mainstream devices.

Despite exploring that option, it seems Samsung may stick with conventional cells while improving what surrounds them. The company has reportedly ordered components that support both SUS and EMC designs, signaling a likely shift in how its next flagship manages power.
