Recent rumors say that Samsung is developing a new Galaxy S25 variant on a diet. The so-called Galaxy S25 Slim will supposedly join the S25 trio, soon be announced at Unpacked. Whether the rumored Galaxy S25 Slim will be revealed on the same day as the base, Plus, and Ultra S25 models is to be determined, and so far, no information about the Galaxy S25 Slim's dimensions has leaked.
Just how thin will the Galaxy S25 Slim be to earn its purported name? Only time will tell, and for now, all we can do is look back at some of Samsung's slimmest smartphones to date for a clue of where the Galaxy S25 Slim might land.
If you ask me, the Galaxy S24 and S24+ aren't thick phones by any means. They measure only 7.6 and 7.7mm, respectively. But let's imagine Samsung wants to push the bar higher with the release of the Galaxy S25 Slim. Can the latter become the thinnest Samsung smartphone to date? And what's Samsung's current record for the slimmest Galaxy phone?
Nothing can beat the Fold series
Counting foldable phones, the Galaxy Z Fold Special Edition takes the cake thanks to an ultra-thin 4.9mm profile when unfolded. Even the standard Galaxy Z Fold 6 has an impressively thin 5.6mm profile.
However, comparing the Fold series with any slab-type phones might be unfair. Galaxy Z Folds have a lot of room for internal components, given their large surface areas. This makes their thin profiles possible.
Then again, it can be argued that the Galaxy Z Flip 6 doesn't have nearly as much surface area as the Fold 6, and yet it has a thin 6.9mm body.
Samsung's slab-type record holder is from 2015
Foldable phones aside, the thinnest smartphone Samsung has ever manufactured isn't even from this decade. It's from 2015, and it's called the Galaxy A8.
Samsung wowed smartphone enthusiasts in the summer of 2015 when it unveiled the Galaxy A8 as its thinnest smartphone ever, and the same A8 still holds the crown today. It measures only 5.9mm. However, it doesn't have modern luxuries such as an ultra-durable Armor Aluminum frame or dust and water resistance.
If I were to guess, given the lack of concrete information, I'd say the Galaxy S25 Slim won't beat the A8 record holder or the Fold series. But in theory, it should at least land somewhere between 5.9 and 7.6mm. And, who knows? Maybe Samsung and the Galaxy S25 Slim will surprise me and set a new thinness standard.
The other question I have on my mind is whether or not it's even worth creating a slimmer slab-type phone in 2025, given how thin the standard models already are. Maybe not, but your opinion might vary. Besides, if rumors are true, the Galaxy S25 Slim might have other aces up its sleeve, including a powerful camera that could outshine the standard and Plus models. The phone's supposedly thin profile might not be its greatest selling point after all, but time will tell.
