Both devices were the first to use this technology, which allowed for higher battery capacity due to higher energy density.
The switch to silicon-carbon batteries will allow Samsung to increase the battery capacity of the Galaxy S26 series without increasing the physical volume of the devices. Silicon-carbon batteries typically have a 10-15% higher energy density than their lithium-ion counterparts, which suggests that a device like the Galaxy S26 Ultra could have a battery capacity of around 5,500 mAh.
