A comparison shows the expected rounded design of the Galaxy S26 Ultra next to the more boxy Galaxy S25 Ultra.

According to PhoneArt, also known as Ice Universe, the dimensions for the upcoming Galaxy S26 Ultra have been obtained, allowing for a comparison with the existing Galaxy S25 Ultra.

The design of the S26 Ultra will likely be a refinement of its predecessor, similar to how the S25 Ultra enhanced the S24 Ultra. The newer model is rumored to have more rounded corners, while maintaining similar screen bezels.

Surprisingly, the Galaxy S26 Ultra is anticipated to be slightly taller and wider than the S25 Ultra. This contradicts an image that suggests the opposite, implying a possible error.

Recent rumors suggest that Samsung will continue its transition to more curved designs. The corners of the S26 Ultra are expected to be more rounded than those of the S25 Ultra, which was already curvier than the S24 Ultra.

This design change may improve comfort and ergonomics. These aspects could be considered more crucial than aesthetics.

The battery capacity remains uncertain. Initial rumors of a 5,500mAh battery have decreased to 5,000mAh.

A recent Weibo post revealing the S26 Ultra's thickness indicates it will be about 0.3mm thinner than the S25 Ultra, making a larger battery unlikely.

Maintaining the 6.89-inch screen size makes a battery upgrade difficult unless Samsung adopts silicon-carbon battery technology, which is not expected even for the Galaxy S26 Edge.

The Galaxy S26 Ultra is still expected to offer improvements in processing power, screen privacy, and camera capabilities.
