Key Differences
-
The iPhone 17 has a 1.45 oz lighter build
The iPhone 17 doesn’t just edge this one; 6.24 oz against 7.69 oz is a lead you’ll feel. Weight shows up every time you hold the phone above your face in bed or type one-handed for a long stretch.
-
The Galaxy S25 Ultra has a higher-resolution 200 MP main camera
Big gap, real consequences. The Galaxy S25 Ultra’s 200 MP versus the iPhone 17’s 48 MP changes how the two compare in daily use. More megapixels on the main camera allow bigger crops and more detail in good light, but sensor size and processing matter just as much.
-
The Galaxy S25 Ultra has an extra rear camera
The iPhone 17 is clearly behind on rear cameras (2 against 4), and that’s one of its biggest weak spots in this matchup. An extra rear camera usually means another focal length (ultra-wide, telephoto or macro) and more freedom in framing.
-
The Galaxy S25 Ultra has a 0.6-inch larger screen
This one isn’t a win or a loss. The Galaxy S25 Ultra is larger here (6.9 in versus 6.3 in), which suits some people and not others. A bigger screen makes reading, video and maps more comfortable, while a smaller one is easier to use with one hand and slips into more pockets.
-
The Galaxy S25 Ultra has a bigger top storage option
On this line of the spec sheet, the Galaxy S25 Ultra is in a different league: 1 TB, next to 512 GB for the iPhone 17. Heavy video shooters and people with large offline libraries benefit from the Galaxy S25 Ultra’s bigger maximum.

Display
Trade-off
In the display category, the iPhone 17 counts 15% higher peak brightness in its favor, and the Galaxy S25 Ultra answers with 8.3% sharper pixel density. Pick the strength that fits your routine; that’s the honest answer for display.
Screen size
iPhone 17: 6.3 in Galaxy S25 Ultra: 6.9 in Screen size is personal. If you watch a lot on your phone, the extra area pays off; if you text one-handed on the go, compact is kinder.
Peak brightness
iPhone 17: 3,000 nits Galaxy S25 Ultra: 2,600 nits Peak figures are usually reached only in short bursts or small areas of the screen, but a higher ceiling still helps outdoor visibility.
Performance
Too close to call
Swap one for the other and you’d lose nothing on performance. On performance alone, you can’t go far wrong with either.
CPU cores
iPhone 17: 6 Galaxy S25 Ultra: 8 Treat the core count as background information; the chipset name tells you far more about real performance.
Memory & Storage
Galaxy S25 Ultra leads
On balance, the Galaxy S25 Ultra leads the memory & storage section, just not by much. Here the Galaxy S25 Ultra offers a bigger top storage option. Most buyers are fine with a base or middle tier, so this is a niche advantage, but a real one if you need it. The memory & storage verdict goes to the Galaxy S25 Ultra.
Max storage
iPhone 17: 512 GB Galaxy S25 Ultra: 1 TB The top storage option only matters if you plan to buy a high-capacity version, but it caps how much you can ever keep on the phone.
Camera
Galaxy S25 Ultra leads
For camera, the verdict is easy: the Galaxy S25 Ultra leads, and not by a little. On its side, the Galaxy S25 Ultra has a higher-resolution 200 MP main camera. The Galaxy S25 Ultra’s higher-resolution main sensor gives you more room to crop, which helps when you can’t get closer. In its favor, the iPhone 17 has a sharper 18 MP selfie camera. Net result: the Galaxy S25 Ultra leads this part of the comparison.
Main camera
iPhone 17: 48 MP Galaxy S25 Ultra: 200 MP Megapixels are only one part of image quality, so treat this as a sign of detail potential, not a verdict on photos.
Rear cameras
iPhone 17: 2 Galaxy S25 Ultra: 4 More cameras help most when each covers a different view, so check the table to see what the Galaxy S25 Ultra’s extra lens adds.
Battery & Charging
iPhone 17 leads
The battery & charging numbers lean toward the iPhone 17, not dramatically but consistently. The iPhone 17 adds faster 25 W wireless charging. Faster wireless charging makes a pad or stand more practical as your main way to top up. If battery & charging is your priority, the iPhone 17 is the phone to pick.
Wireless charging
iPhone 17: 25 W Galaxy S25 Ultra: 15 W If you rely on a wireless pad at your desk or bedside, the iPhone 17 refills quicker there.
