Samsung Galaxy S25 Ultra could be thinner than all Ultra flagship phones

Samsung hasn’t dropped any hints about the Galaxy S25 series yet, but before the company gears up to launch its next flagship line, numerous leaks have been doing the rounds online suggesting the design of the top-end Galaxy S25 Ultra. While a set of renders recently revealed the flagship’s design, a new rumor claims it will be slimmer than other flagship phones from Apple and Google. Samsung is expected to unveil the Galaxy S25 Ultra early next year alongside the Galaxy S25 and Galaxy S25+. The phone is expected to come with Snapdragon 8 Gen 4 SoC.

Leading tipster Ice Universe (@UniverseIce) on X claims that the Samsung Galaxy S25 Ultra will be “the thinnest and lightest of all upcoming Ultra flagship phones, including the iPhone 16 Pro Max and Pixel 9 Pro XL.”

It’s unclear how Samsung plans to shrink the size of its Galaxy S24 Ultra successor, and the leak doesn’t include any information on the phone’s dimensions. The leak comes shortly after the tipster revealed the Galaxy S25 Ultra’s design via alleged renders.

While we don’t have official dimensions for the iPhone 16 Pro Max yet, early rumors have suggested a 8.25mm thick profile for the phone. For comparison, the Pixel 9 Pro XL has a thickness of 8.5mm and weighs 221 grams. The Galaxy S20 Ultra is 8.6mm thick and weighs 232 grams.

Based on these measurements, we can speculate that the Galaxy S25 Ultra could be thinner than 8.25mm and weigh 220 grams or less. However, these design hints should also be taken with a grain of salt.
