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×
Only a little separates them: 5× on the Galaxy S25 Ultra, 4× on the iPhone 17 Pro Max. The Galaxy S25 Ultra reaches further with real optics, which pays off for wildlife, stages and sports from the stands.
-
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 Max) and one of the main reasons to choose between them. The count alone doesn’t guarantee quality, but the Galaxy S25 Ultra gives you more lenses to choose from.
-
The Galaxy S25 Ultra has a 0.53 oz lighter build
It’s a fine margin, and it favors the Galaxy S25 Ultra (7.69 oz versus 8.22 oz). Weight shows up every time you hold the phone above your face in bed or type one-handed for a long stretch.
-
The iPhone 17 Pro Max has a bigger top storage option
The spread here is large: 2 TB on the iPhone 17 Pro Max versus 1 TB on the Galaxy S25 Ultra. Expect to notice it. 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 iPhone 17 Pro Max has faster 25 W wireless charging
Of all the specs we compared, this is one where the iPhone 17 Pro Max makes its strongest case: 25 W against 15 W. If you rely on a wireless pad at your desk or bedside, the iPhone 17 Pro Max refills quicker there.

Display
Trade-off
The iPhone 17 Pro Max leans on 15% higher peak brightness in this section, while the Galaxy S25 Ultra leans on 8.3% sharper pixel density. If you’re torn on display, the other sections may help break the tie.
Peak brightness
iPhone 17 Pro Max: 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.
Pixel density
iPhone 17 Pro Max: 460 ppi Galaxy S25 Ultra: 498 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. Treat performance as common ground and look elsewhere for the deciding factor.
CPU cores
iPhone 17 Pro Max: 6 Galaxy S25 Ultra: 8 Treat the core count as background information; the chipset name tells you far more about real performance.
Memory & Storage
iPhone 17 Pro Max leads
Slight edge to the iPhone 17 Pro Max on memory & storage. Most buyers could live happily with either. The iPhone 17 Pro Max pulls ahead with a bigger top storage option. Heavy video shooters and people with large offline libraries benefit from the iPhone 17 Pro Max’s bigger maximum. That makes the iPhone 17 Pro Max the natural choice for buyers focused on memory & storage.
Max storage
iPhone 17 Pro Max: 2 TB 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
The camera comparison is one-sided. The Galaxy S25 Ultra leads where it counts. In its favor, the Galaxy S25 Ultra has 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 Max adds a sharper 18 MP selfie camera. For anyone who cares most about camera, the Galaxy S25 Ultra is the safer choice.
Main camera
iPhone 17 Pro Max: 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 Max: 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 Max leads
On battery & charging, the difference is modest, and it favors the iPhone 17 Pro Max. The iPhone 17 Pro Max 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. If battery & charging is your priority, the iPhone 17 Pro Max is the phone to pick.
Wireless charging
iPhone 17 Pro Max: 25 W Galaxy S25 Ultra: 15 W Faster wireless charging makes a pad or stand more practical as your main way to top up.
