To fold or not to fold, that is the question? We've got the answer with this head-to-head comparison of the Samsung Galaxy S25 Ultra and the Samsung Galaxy Z Fold 6.

The two devices vary when compared side-by-side, as the S25 Ultra is taller, wider, and thinner at its 162.8 x 77.6 x 8.2 mm measurements. The Fold 6 measures 153.5 x 68.1 x 12.1 mm when closed, and 153.5 x 132.6 x 5.6 mm when opened.

Samsung is said to be adding battery-extending technology to the Galaxy S26 smartphone range, though it should arguably have been present in the Galaxy S25 already. South Korean outlet Fnnews has issued a fresh report claiming that Samsung is pondering the use of silicon-carbon (Si-C) battery technology in next year’s Galaxy S26 family.
