We’re in Samsung season right now, as in a few days we’re expecting the Samsung Galaxy S25, Samsung Galaxy S25 Plus, and Samsung Galaxy S25 Ultra to launch, and the Samsung Galaxy S25 Slim might not be too far behind. .
This rumored new addition to Samsung’s Galaxy S line is – as the name suggests – reportedly much thinner than the company’s typical flagships.
But slimming down in size might not mean slimming down too many of the specs, as there’s a 200MP camera, a Snapdragon 8 Elite chipset and more.
Below you’ll find everything we’ve heard about the Samsung Galaxy S25 Slim so far, and we’ll update this article whenever more Galaxy S25 Slim news arrives.
Cut to the leg
- What is it? An advanced, slim Samsung phone
- When is it out? Possibly May
- How much will it cost? Probably over $999 / £999 / AU$1,699
Landing probably in May
- Most leaks point to a launch in or around May
- Expect it to be priced somewhere between the S25 Plus and Ultra
We first heard of a Samsung Galaxy S25 Slim back in October, with a source claiming that this phone would likely land a few months after the rest of the Samsung Galaxy S25 lineup. Since these phones are set to be announced on January 22, that would mean an April or May launch.
However, this source cautioned that the S25 Slim may only be released in limited quantities or regions, so Samsung can gauge how much interest there is in it before committing to a wider release for a model next year.
Then in November, a model number for a phone believed to be the Samsung Galaxy S25 Slim was spotted on the GSMA IMEI database. This told us a few things. For one, it provided more evidence that the phone existed, and for another, the model number ended with a ‘U’, which indicates a US model, so whether its availability is limited or not, it’s likely to land in the US at least .
This finding also pointed to a release in or around May, as Samsung phones tend to be added to this database about six months before they launch.
Another model number for the S25 Slim has since surfaced, this time with a ‘B’ at the end, typically signifying a phone Samsung will sell in each region it operates in. So the Galaxy S25 Slim might not be limited to certain regions after all.
In any case, a source claimed in mid-December that the Samsung Galaxy S25 Slim would land in the 2nd quarter (so between April and June), and in January 2025 we heard to expect the Galaxy S25 Slim in May.
That said, an early rumor said that the Samsung Galaxy S25 Slim was in the final stages of development, and that Samsung hoped to have it ready in time to launch it alongside the rest of the Galaxy S25 lineup on January 22. So there is some disagreement.
In terms of price, we haven’t heard much, but based on the rumored specs and model number, it’s likely that the Samsung Galaxy S25 Slim will be positioned somewhere between the Samsung Galaxy S25 Plus and the Samsung Galaxy S25 Ultra.
We also don’t know how much those phones will cost yet, but for reference, the Samsung Galaxy S24 Plus starts at $999 / £999 / AU$1,699 and the Samsung Galaxy S24 Ultra starts at $1,299.99 / £1,249 / AU$2,199, so a price a place between the two is likely.
Can you trust these rumors?
Almost all Samsung Galaxy S25 Slim release date leaks point to the same launch window, with May sounding like the most likely month.
Although one source suggested a January launch, we would think that this is very unlikely to happen as we have not heard this from other sources and as we would expect to have heard far more Galaxy S25 Slim leaks and rumors now if it landed that fast. However, it is believable that the phone might be teased during the Galaxy Unpacked event.
A slim body and a large screen
- Expect a sleek design and a different S24-like appearance
- Could only be 6.4mm thick
- The screen can be 6.66 inches
The biggest Samsung Galaxy S25 design leak to date comes in the form of several renders shared by @Onleaks (a reputable tipster) in collaboration with SmartPrix.
You can see some of these below, and they show a phone that looks like the Samsung Galaxy S24, complete with slim bezels, a glass back, a flat metal frame, a flat screen and a triple-lens camera.
The source claims the Samsung Galaxy S25 Slim has dimensions of 159 x 76 x 6.4mm (increases to 8.3mm if you include the camera bump). In comparison, the Samsung Galaxy S24 Plus (which is expected to have a screen the same size as) is 158.5 x 75.9 x 7.7mm.
Picture 1 of 2
While we’d take these claims with a grain of salt, another source has also said that the Samsung Galaxy S25 Slim is somewhere between 6.0 and 6.9mm thick.
This might sound very thin, but yet another source has shown a comparison image that reveals that the Galaxy S25 Slim might not be noticeably thinner than the rest of the Galaxy S25 series. And indeed, as thin as the Galaxy S25 Slim may be, it’s reportedly not as thin as Samsung hoped to make it.
As for the display, the source of the renders above claims it to be somewhere between 6.7 and 6.8 inches, while another source got more specific, saying the Samsung Galaxy S25 Slim has a 6.66-inch display. That would put it in line with the Galaxy S24 Plus, and probably the Samsung Galaxy S25 Plus as well.
Can you trust these rumors?
The source for the Samsung Galaxy S25 Slim renders has an excellent track record, so we’d say they’re probably accurate, and since all sources pretty much agree on the screen size and thickness, we’d think those details are likely more or less less correct.
Ultra level cameras
- Several sources point to a high-spec camera
- A triple-lens snapper is likely
- Possibly a 200 MP main, 50 MP ultra-wide and 50 MP telephoto
The earliest Samsung Galaxy S25 Slim camera leak suggested that this phone would have an “Ultra” camera, presumably meaning similar camera hardware to the Samsung Galaxy S24 Ultra or Galaxy S25 Ultra.
Later, the same source similarly said that the Samsung Galaxy S25 Slim would have a “stronger” camera than the standard Galaxy S25.
Another source has since become more specific, claiming that the Samsung Galaxy S25 Slim will have a 200MP main camera, a 50MP ultra-wide and a 50MP telephoto with 3.5x optical zoom. This claim likely fits with the leak above, as a 200MP main sensor would see it match the S24 Ultra, and those specs are likely better than what you’ll find on the standard S25.
Finally, we’ve heard elsewhere that the telephoto camera on the S25 Slim could have an ALoP (All Lenses on Prism) design, making it thinner than most telephoto lenses.
Can you trust these rumors?
We’re a little skeptical of the claim that the Samsung Galaxy S25 Slim will have a 200MP main camera and two 50MP snappers, simply because the source doesn’t have much of a track record.
But this is consistent with the other, vague camera claims we’ve heard from more credible sources, so it’s certainly possible.
At the very least, the Samsung Galaxy S25 Slim will likely have a triple camera, as that’s what it’s shown with in the renders we’ve seen.
Top-end power
- Leaks point to a high-end Snapdragon 8 Elite chipset
- 12GB of RAM also seems likely
Our first real Samsung Galaxy S25 Slim specs came in December 2024, when we heard that this – like the rest of the Samsung Galaxy S25 range – was likely to feature a top-end Snapdragon 8 Elite chipset.
Recently, the Galaxy S25 Slim appeared in a benchmark with exactly that chipset and 12GB of RAM. Its score wasn’t as impressive as we’d expect from such a top-tier chipset, but that’s probably just because the phone’s hardware and software were still being developed and optimized.
Another rumor has since repeated that the chipset and the amount of RAM for the Samsung Galaxy S25 Slim. So this could be an extremely powerful phone that offers performance that is in line with the rest of the Samsung Galaxy S25 series.
Can you trust these rumors?
Several sources have pointed to a Snapdragon 8 Elite chipset and 12GB of RAM. So there’s a good chance that’s what we’ll get, especially since it’s what we expect from the Samsung Galaxy S25 and Samsung Galaxy S25 Plus.
A worryingly small battery
- Could have a very small battery
- Most leaks suggest it will be under 4,000mAh
- A source says instead that it will be 4,700 mAh or larger
One area where the Samsung Galaxy S25 Slim may not impress is its battery, with an early leak suggesting that Samsung had failed to make the battery as energy-dense as hoped, which – combined with the phone’s slim build – could mean a battery with lower capacity than you would expect from a phone with a screen of this size.
That has been echoed by a more recent claim that the Galaxy S25 Slim’s battery will be somewhere between 3,000 mAh and 4,000 mAh.
That said, the source of the renders above said its battery is “significantly” larger than 3,050mAh, so it could at least approach 4,000mAh.
Or these sources could be wrong, as we’ve heard elsewhere that the Samsung Galaxy S25 Slim may have a battery between 4,700 mAh and 5,000 mAh.
Can you trust these rumors?
While one source points to a large battery in the Galaxy S25 Slim, they don’t have much of a track record, and it’s hard to believe that Samsung would be able to fit such a large battery in such a slim phone.
So the claims of the battery being somewhere between 3,000 mAh and 4,000 mAh are more believable, but we hope it will at least be at the upper end of that range.
