Samsung has increased the battery capacity to 4,300 mAh on the S26, while somehow maintaining the same thickness as last year’s S25. However, the S26+ has the same 4,900mAH battery as its predecessor. All S26 devices will launch with 256GB of storage and 12GB of RAM, with bigger storage options available. With the S26, Samsung has slightly increased the screen size to 6.3 inches, up from last year's 6.2-inch S25.
