Key Differences
-
The Galaxy S25 Ultra has a higher-resolution 200 MP main camera
When it comes to main camera, the Galaxy S25 Ultra wins comfortably with 200 MP against 48 MP. The Galaxy S25 Ultra’s higher-resolution main sensor gives you more room to crop, which helps when you can’t get closer.
-
The Galaxy S25 Ultra has 5× optical zoom versus 4×
Think of it as a tiebreaker rather than a deal-breaker: 5× for the Galaxy S25 Ultra, 4× for the iPhone 17 Pro. Higher optical zoom lets you frame distant subjects tightly without losing detail to digital cropping.
-
The Galaxy S25 Ultra has an extra rear camera
It’s a lopsided result (4 for the Galaxy S25 Ultra, 3 for the iPhone 17 Pro) and one of the main reasons to choose between them. An extra rear camera usually means another focal length (ultra-wide, telephoto or macro) and more freedom in framing.
-
The iPhone 17 Pro has a 0.42 oz lighter build
On paper, the iPhone 17 Pro is a touch ahead here, listing 7.27 oz against 7.69 oz. 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 0.6-inch larger screen
For screen size, the figures are 6.9 in for the Galaxy S25 Ultra and 6.3 in for the iPhone 17 Pro. Treat it as a question of preference, not quality. A larger display also means a larger phone overall, so this is as much about your hands and pockets as it is about the picture.
-
The iPhone 17 Pro has faster 25 W wireless charging
The spread here is large: 25 W on the iPhone 17 Pro versus 15 W on the Galaxy S25 Ultra. Expect to notice it. If you rely on a wireless pad at your desk or bedside, the iPhone 17 Pro refills quicker there.

Display
Trade-off
The display comparison comes down to priorities: 15% higher peak brightness on the iPhone 17 Pro, or 8.3% sharper pixel density on the Galaxy S25 Ultra. Think about how you’ll use the phone; that’s what settles display.
Screen size
iPhone 17 Pro: 6.3 in Galaxy S25 Ultra: 6.9 in 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.
Peak brightness
iPhone 17 Pro: 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
On paper, the performance comparison ends all square. Either phone will serve you equally well on performance.
CPU cores
iPhone 17 Pro: 6 Galaxy S25 Ultra: 8 Phone chips mix large and small cores, so a different count mostly reflects a different design rather than a clear speed gap.
Memory & Storage
Too close to call
You can skip ahead if memory & storage was your deciding factor: the two are evenly matched here. Don’t let memory & storage decide this one; look at the other sections instead.
Camera
Galaxy S25 Ultra leads
This is one of the Galaxy S25 Ultra’s strongest areas. On camera, the iPhone 17 Pro falls well short. Here the Galaxy S25 Ultra offers a higher-resolution 200 MP main camera. Megapixels are only one part of image quality, so treat this as a sign of detail potential, not a verdict on photos. The iPhone 17 Pro delivers a sharper 18 MP selfie camera. Anyone shopping mainly on camera should start with the Galaxy S25 Ultra.
Main camera
iPhone 17 Pro: 48 MP Galaxy S25 Ultra: 200 MP More megapixels on the main camera allow bigger crops and more detail in good light, but sensor size and processing matter just as much.
Optical zoom
iPhone 17 Pro: 4× Galaxy S25 Ultra: 5× Digital zoom can fake reach, but optical zoom is where the detail actually comes from.
Battery & Charging
iPhone 17 Pro leads
The iPhone 17 Pro takes battery & charging by a nose. The iPhone 17 Pro wins here with faster 25 W wireless charging. Wireless charging is usually slower than a cable, so this edge matters mainly to people who value the convenience. Net result: the iPhone 17 Pro leads this part of the comparison.
Wireless charging
iPhone 17 Pro: 25 W Galaxy S25 Ultra: 15 W Faster wireless charging makes a pad or stand more practical as your main way to top up.
Software & Updates
On software & updates, the useful details are the names in the table: what each one uses, not a figure we can rank.
