TL;DR Leaked Galaxy S26 vs S25 spec sheets show steady internal upgrades across the board.
The base S26 might feature a larger 6.3-inch display, a bigger 4,300mAh battery, and a shift to the Snapdragon 8 Elite Gen 5 or Exynos 2600, depending on the region.
The S26 Ultra could retain its 6.9-inch QHD screen and quad-camera setup, but may upgrade to a new M14 OLED panel for improved efficiency.
Samsung’s upcoming flagship lineup has been leaking for months, and if you were hoping the Galaxy S26 series would reinvent the wheel, you might want to lower your expectations. Recent side-by-side spec comparisons with the Galaxy S25 suggest Samsung is sticking to a familiar upgrade approach.

You also get a 4,300mAh battery, which would be a welcome improvement over the S25’s 4,000mAh pack.
The biggest change is the processor. The S26 will use either the Snapdragon 8 Elite Gen 5 or the Exynos 2600, depending on the region. That regional split isn’t new, but the Exynos comeback matters because Samsung is betting hard on its in-house chip for AI workloads this generation.
Elsewhere, the 50MP main camera and 12MP ultrawide remain unchanged on paper, and the 10MP 3× telephoto keeps the same sensor size. Storage could now start at 256GB, as the 128GB option could be on its way out.
