Samsung Galaxy S25 specs: all the key specs for every model

The Samsung Galaxy S25 and its siblings – the Samsung Galaxy S25 Plus and Samsung Galaxy S25 Ultra – may well end up ranking among the best phones of 2025.

Of course, it’s too early to say that for sure, but their specs certainly impress – these are high-end handsets with massive power upgrades and various other improvements on their predecessors.

Below, we’ve detailed all the key specs for all three of these phones, but to learn more about how they perform in practice, check out our hands-on Samsung Galaxy S25 review, our hands-on Samsung Galaxy S25 Plus review, and our hands-on Samsung Galaxy S25 Ultra review.

Samsung Galaxy 25 specs

The Samsung Galaxy S25 has a 6.2-inch 1080 x 2340 AMOLED screen with a 120Hz refresh rate, a peak brightness of 2,600 nits, and around 416 pixels per inch. Those specs are all in line with the Samsung Galaxy S24, but with the arguable exception of its resolution they’re all also very high-end.

The main upgrade you will find in the Galaxy S25 is its chipset, which is a Snapdragon 8 Elite for Galaxy – this being a customized version of Qualcomm’s exceptionally powerful Snapdragon 8 Elite chipset.

Samsung claims that this chipset’s CPU performance is 37% better than the Snapdragon 8 Gen 3 in the Galaxy S24, with its GPU performance being 30% better and its NPU (neural processing unit) performance being 40% better. So this is a huge upgrade.

And the RAM has also been upgraded, with the Samsung Galaxy S25 coming with 12GB, rather than the 8GB of its predecessor. Storage though is once again a choice of 128GB, 256GB, or 512GB – though the last of those is available in both the UK and Australia this year.

As for the camera, the Samsung Galaxy S25 has a 50MP f/1.8 main sensor, a 12MP f/2.2 ultra-wide (with a 120-degree field of view), and a 10MP f/2.4 telephoto (with 3x optical zoom), along with a 12MP f/2.2 front-facing camera. Those specs are all the same as last year, but while Samsung hasn’t improved the Galaxy S25’s camera hardware, it has improved the editing tools and AI features that the cameras can access.

Finally, there’s the Samsung Galaxy S25’s battery, which at 4,000mAh hasn’t increased in size, and nor has the charging speed increased, with it once again topping out at 25W wired and 15W wireless.

So then, the main spec upgrades here are the chipset and the amount of RAM.

Samsung Galaxy 25 Plus specs

The Samsung Galaxy S25 Plus’s screen is 6.7 inches, just like its predecessor’s display, and just like that phone it’s a 120Hz AMOLED display with a 1440 x 3120 resolution, a peak brightness of 2,600 nits, and around 513 pixels per inch.

As with the standard Samsung Galaxy S25, the main upgrade here is the chipset, which is a Snapdragon 8 Elite for Galaxy. We’ve detailed the performance uplift this offers in the section above, but in short this is likely to be the most powerful chipset available to Android phones for most of 2025.

However, unlike the base Galaxy S25 there’s no RAM upgrade here, with both the Samsung Galaxy S25 Plus and its predecessor having 12GB. Both phones also come in 256GB and 512GB storage configurations.

The cameras are the same both as the Samsung Galaxy S25’s and as the Samsung Galaxy S24 Plus’s, meaning you get a 50MP f/1.8 main sensor, a 10MP f/2.4 telephoto camera (with 3x optical zoom), a 12MP f/2.2 ultra-wide (with a 120-degree field of view), and a 12MP f/2.2 selfie camera. As with the base S25 though there are some improvements behind the scenes, and in particular where it comes to AI-powered editing tools.

That just leaves the battery, and there’s no upgrade here either, with the Samsung Galaxy S25 Plus having a 4,900mAh one with 45W wired charging and 15W wireless charging.

So the only significant upgrade here is the chipset, which means the Samsung Galaxy S25 Plus is arguably the least improved of these three handsets.

Samsung Galaxy 25 Ultra specs

The Samsung Galaxy S25 Ultra is the most high-spec of these phones, and it’s also had some improvements that the other models haven’t, including its screen, which at 6.9 inches is slightly bigger than the 6.8-inch Samsung Galaxy S24 Ultra.

The other screen specs haven’t changed though, meaning you get an AMOLED display with a 1440 x 3120 resolution (for around 498 pixels per inch), a 120Hz refresh rate, and a peak brightness of 2,600 nits.

The chipset has had the same upgrade as the other models, meaning the Samsung Galaxy S25 Ultra is powered by a new and extremely capable Snapdragon 8 Elite for Galaxy chipset, and as with the Galaxy S25 Plus it comes with 12GB of RAM.

That RAM amount is no upgrade on the Samsung Galaxy S24 Ultra, which is a shame, especially as a 16GB model did launch, but it’s only available in South Korea, China, and Taiwan.

Storage comes in at a choice of 256GB, 512GB, and 1TB, just like last year, but unlike the rest of the S25 series one of the cameras has been improved on this phone.

The Samsung Galaxy S25 Ultra has a 200MP f/1.7 main camera, a 50MP f/1.9 ultra-wide (with a 120-degree field of view), a 50MP f/3.4 periscope (with 5x optical zoom), and a 10MP f/2.4 telephoto (with 3x optical zoom), as well as a 12MP f/2.2 front-facing camera.

Of those, it’s the ultra-wide that’s been improved, as the Galaxy S24 Ultra has just a 12MP ultra-wide camera.

But now we’re back to things that haven’t really been upgraded, with the battery being 5,000mAh once again, and charging a 45W. Though thanks to a 40% larger vapor chamber the phone will hopefully be more battery efficient.

So the main improvements here are a new chipset, a bigger screen, and an upgraded ultra-wide camera. Oh, and the Galaxy S25 Ultra should also be more durable, as it replaces its predecessor’s Corning Gorilla Armor with Gorilla Armor 2.
