Identical specs don’t help you choose, so “Differences only” hides them.
| Spec | iPhone 17 Pro | Galaxy S25 Ultra | Difference |
|---|---|---|---|
| Weight | 206 gLighter | 218 g | iPhone 17 Pro · 12 g lighter (6%) |
Why this matters. Weight affects one‑handed comfort and pocketability. A few grams rarely matter; 20 g or more is usually noticeable. | |||
| Thickness | 8.75 mm | 8.2 mm | iPhone 17 Pro · 0.55 mm thicker (7%) |
| Height | 150 mm | 162.8 mm | Galaxy S25 Ultra · 12.8 mm taller (9%) |
| Width | 71.9 mm | 77.6 mm | Galaxy S25 Ultra · 5.7 mm wider (8%) |
| Water & dust rating | IP68 | IP68 | Same |
Why this matters. IP68: the first digit (6) is dust‑tight, the second (8) is rated for continuous immersion under conditions set by the manufacturer. | |||
1 identical spec hidden in this section
| Spec | iPhone 17 Pro | Galaxy S25 Ultra | Difference |
|---|---|---|---|
| Screen size | 6.3″ | 6.9″ | Galaxy S25 Ultra · 0.6″ larger |
| Panel | OLED | OLED | Same |
| Resolution | 1206 × 2622 | 1440 × 3120 | Different |
| Pixel density | 460 ppi | 498 ppi | Galaxy S25 Ultra · 38 ppi denser (8%) |
Why this matters. Above roughly 400 ppi at phone viewing distance, most people struggle to see individual pixels. | |||
| Refresh rate | 120 Hz | 120 Hz | Same |
Why this matters. Higher refresh rates can make scrolling and motion look smoother, particularly in games and fast‑moving interfaces. Most phones vary the rate to save power. | |||
| Brightness (typical) | 1,000 nits | 2,600 nits | Galaxy S25 Ultra · 1,600 nits brighter (160%) |
Why this matters. Manufacturers measure brightness differently (typical, HDR peak, outdoor boost). Compare like‑for‑like figures only. | |||

| Spec | iPhone 17 Pro | Galaxy S25 Ultra | Difference |
|---|---|---|---|
| Chipset | Apple A19 Pro | Snapdragon 8 Elite | Different |
| RAM | 12 GB | 12 GB | Same |
Why this matters. More RAM lets more apps stay open in the background. Beyond 8–12 GB the everyday difference is small. | |||
| Storage (max listed) | 1,024 GB | 1,024 GB | Same |
Why this matters. DuelVS lists one storage figure per model, usually the largest configuration. Check the variant you would actually buy. | |||
| Geekbench 6 single‑core | 3,781 | 3,057 | iPhone 17 Pro · 724 higher (24%) |
Data note. Benchmark figures come from mixed sources and test versions. Treat small gaps as noise. | |||
| Geekbench 6 multi‑core | 9,553 | 9,846 | Galaxy S25 Ultra · 293 higher (3%) |

| Spec | iPhone 17 Pro | Galaxy S25 Ultra | Difference |
|---|---|---|---|
| Rear cameras | 48 + 48 + 48 MP | 200 + 50 + 50 + 10 MP | Different |
Why this matters. Megapixels describe resolution, not image quality. Sensor size, lens and processing usually matter more. | |||
| Front camera | 18 MP | 12 MP | iPhone 17 Pro · 6 MP higher‑res (50%) |
| Max video | 4K · 120 fps | 8K · 30 fps | Different |

|---|---|---|---|
| Battery capacity | 4,252 mAh | 5,000 mAhMore | Galaxy S25 Ultra · 748 mAh more (18%) |
Why this matters. Capacity is the size of the tank, not the mileage. Chip efficiency and screen settings decide real battery life. | |||
| Wired charging (rated) | 40 W | 45 WHigher | Galaxy S25 Ultra · 5 W higher (13%) |
| Wireless charging (rated) | 30 WHigher | 15 W | iPhone 17 Pro · 15 W higher (100%) |

| Spec | iPhone 17 Pro | Galaxy S25 Ultra | Difference |
|---|---|---|---|
| Wi‑Fi (newest supported) | Wi‑Fi 7 | Wi‑Fi 7 | Same |
Why this matters. Wi‑Fi 7 can be faster and steadier on a Wi‑Fi 7 router. On older routers the difference disappears. | |||
| Bluetooth | 6.0 | 5.4 | Different |
| USB‑C data | USB 3.2 | USB 3.2 | Same |
Why this matters. USB 2 transfers files much more slowly than USB 3.x over a cable. Charging is unaffected. | |||
| SIM | 1 SIM + 1 eSIM | 2 SIM + 2 eSIM | Different |
| LDAC audio codec | No | Yes | Only Galaxy S25 Ultra |
| 3.5 mm headphone jack | No | No | Same |

How this comparison works
Every product in a category uses the same fields and units. Rows highlight a difference. A direction label such as “Lighter” or “More” appears only on fields where DuelVS’s methodology defines which way is generally preferable. Nothing here declares an overall winner.
