Samsung may be preparing to improve the battery experience on its Galaxy S26 series with two new upgrades. According to reports, the company is working with ITM Semiconductor to add more advanced battery protection circuits, as well as a stronger “SUS CAN” stainless steel battery casing.
These upgrades could mean bigger batteries and possibly longer life for the Galaxy S26 phones. The new protection circuits, built with epoxy molding compound (EMC) technology, protect against overcharging, overheating, and physical stress. By making the circuits smaller, Samsung can leave more room for a bigger battery pack inside each phone.
Rumors suggest the Galaxy S26 Ultra could feature a 5,500mAh battery—about 10% larger than the Galaxy S25 Ultra. The new stainless steel battery casing is designed to allow even higher capacity batteries than used in previous flagships.
However, Samsung does not seem to be adding the more advanced silicon-carbon (Si-C) battery technology, used by some other brands. Si-C batteries offer even higher capacity in a smaller size, as seen in phones like the OnePlus 13 or Nothing Phone 3.
Even so, the new protection features in the Galaxy S26 could allow for faster charging and better battery safety, if not the absolute largest battery on the market.
The Galaxy S26 series is expected to launch next year. Stay tuned for more updates as new details come in about Samsung’s next flagship and its battery technology.
