an ultra-thin design… for what purpose?

Samsung’s next ultra high-end mobile is expected to arrive in early 2025. But the many rumors surrounding its release continue to flourish on the internet.

There is no question of leaving the field open to Apple and its iPhone 16. In a few months, Samsung should present its Galaxy S25 Ultra, a hyper high-end version of its future star smartphone. A sort of ultimate incarnation of the brand’s know-how, Samsung’s phone will, a priori, focus on design and finesse.

The prolific leaker Ice Universe actually claimed on X that the S25 Ultra would be just 8.2mm thick. Beyond the fact that that’s even thinner than we thought a few weeks ago, it would also propel the S25 into the delicate position of Samsung’s thinnest phone in years. Only the Galaxy Note 20 Ultra has been thicker in recent times, at 8.1mm. That would also make it the thinnest Galaxy S Ultra ever.

An aesthetic advantage?

While we can highlight the technical feat that this would represent – Samsung would thus manage to put 4 cameras, an ultra high-end chip and 16 GB of RAM in a mobile barely thicker than 3 stacked €1 coins – we can also wonder if this race for thinness is relevant in the current mobile landscape.

After a Galaxy S24 Ultra with fairly sharp edges, it seems that Samsung wants to put a little more emphasis on comfort in the hand with this new model. While thinness and lightness can come into play in this calculation, going too far in this direction can also be counterproductive, as gripping is sometimes easier on a mobile with a little belly.

Technical issues

But even beyond purely aesthetic considerations, the thinness poses several technical problems. First, it requires cramming all the components into an extremely small space, making heat management issues extremely significant. With a processor as powerful as the Snapdragon 8 Gen 4, Samsung’s technical choices could create significant engineering challenges.

All round, already a first glimpse of the Samsung Galaxy S25 Ultra?

And that’s without even mentioning the problems this could cause with the battery. According to the latest news, the S25 Ultra should have a 5000 mAh battery. Enough to give the phone a nice battery life, but in such a thin body, it can also cause problems. As a reminder, the infamous Galaxy Note 7 was 2 mm thinner… but had a battery of only 3500 mAh. Let’s hope that Samsung has learned its lesson and doesn’t repeat the same mistakes.
