Key Differences
-
The iPhone 17 has 256 GB of base storage instead of 128 GB
The Galaxy S25 gives up a lot on base storage: 128 GB, compared with 256 GB on the iPhone 17. The iPhone 17 starts with more room, which means fewer “storage full” warnings and less time deleting old videos.
-
The Galaxy S25 has an extra rear camera
Few buyers will miss this one. The Galaxy S25 brings 3 to the table; the iPhone 17 brings 2. The count alone doesn’t guarantee quality, but the Galaxy S25 gives you more lenses to choose from.
-
The Galaxy S25 has a 0.53 oz lighter build
A modest but measurable lead goes to the Galaxy S25: 5.71 oz compared with 6.24 oz. The Galaxy S25 is easier on your wrist during long reading or gaming sessions.
-
The iPhone 17 has a sharper 48 MP ultra-wide
When it comes to ultra-wide camera, the iPhone 17 wins comfortably with 48 MP against 12 MP. A sharper ultra-wide keeps more detail at the edges of landscape, architecture and group shots.
-
The iPhone 17 has faster 25 W wireless charging
It’s a lopsided result (25 W for the iPhone 17, 15 W for the Galaxy S25) and one of the main reasons to choose between them. Faster wireless charging makes a pad or stand more practical as your main way to top up.
-
The iPhone 17 has a sharper 18 MP selfie camera
The spread here is large: 18 MP on the iPhone 17 versus 12 MP on the Galaxy S25. Expect to notice it. Front cameras are often an afterthought, so a higher-resolution sensor is a small but welcome edge for the iPhone 17.
Design & Size
- iPhone 17 5.89 in × 2.81 in × 0.31 in

A larger body can leave more room inside, while a smaller one is easier to live with in tight spaces. Here, the iPhone 17 is the larger phone. The Galaxy S25 is 0.53 oz lighter, making the iPhone 17 the heftier of the two. Pick the Galaxy S25 and you get a profile 0.03 in thinner.

Display
iPhone 17 leads
No contest in display: the iPhone 17 is the stronger of the two. The iPhone 17 wins here with 15% higher peak brightness. Peak brightness decides how readable the screen stays in direct sunlight and how punchy HDR content looks. If this section decides it for you, choose the iPhone 17.
Peak brightness
iPhone 17: 3,000 nits Galaxy S25: 2,600 nits If you use your phone outdoors a lot, the iPhone 17’s brighter panel is the one that holds up better at midday.
Pixel density
iPhone 17: 460 ppi Galaxy S25: 416 ppi Higher pixel density keeps text and fine detail crisper, although the benefit shrinks once both panels are already sharp at normal viewing distance.
Performance
Too close to call
Evenly matched is the fairest summary of the performance section. In short, performance is a draw; the decision lies elsewhere.
CPU cores
iPhone 17: 6 Galaxy S25: 8 Treat the core count as background information; the chipset name tells you far more about real performance.
Memory & Storage
iPhone 17 leads
The memory & storage comparison is one-sided. The iPhone 17 leads where it counts. The iPhone 17 answers with 256 GB of base storage instead of 128 GB. If you shoot a lot of video or keep music and maps offline, base storage is one of the specs you’ll feel most over the years. Anyone shopping mainly on memory & storage should start with the iPhone 17.
Base storage
iPhone 17: 256 GB Galaxy S25: 128 GB Base storage is what you get without paying extra. Photos, videos and apps add up quickly, so more space at the entry price is real value.
Camera
iPhone 17 leads
If camera is high on your list, the iPhone 17 makes the stronger case by a wide margin. The iPhone 17 scores with a sharper 48 MP ultra-wide. Ultra-wide cameras often lag behind the main one, so the iPhone 17’s higher resolution helps narrow that gap. The Galaxy S25 comes with an extra rear camera. In short, the iPhone 17 is the better-equipped phone for camera.
Rear cameras
iPhone 17: 2 Galaxy S25: 3 An extra rear camera usually means another focal length (ultra-wide, telephoto or macro) and more freedom in framing.
Ultra-wide camera
iPhone 17: 48 MP Galaxy S25: 12 MP If you rarely switch to the wide view, this won’t matter much; if you use it often, it will.
Battery & Charging
iPhone 17 leads
The iPhone 17 has the slight upper hand on battery & charging. The iPhone 17 adds faster 25 W wireless charging. If you rely on a wireless pad at your desk or bedside, the iPhone 17 refills quicker there. On battery & charging alone, the iPhone 17 gets the nod.
Wireless charging
iPhone 17: 25 W Galaxy S25: 15 W Wireless charging is usually slower than a cable, so this edge matters mainly to people who value the convenience.
