Identical specs don’t help you choose, so “Differences only” hides them.
| Spec | iPhone 17 | Galaxy S25 | Difference |
|---|---|---|---|
| Weight | 177 g | 162 gLighter | Galaxy S25 · 15 g lighter (9%) |
Why this matters. Weight affects one‑handed comfort and pocketability. A few grams rarely matter; 20 g or more is usually noticeable. | |||
| Thickness | 7.95 mm | 7.2 mm | iPhone 17 · 0.75 mm thicker (10%) |
| Height | 149.6 mm | 146.9 mm | iPhone 17 · 2.7 mm taller |
| Width | 71.5 mm | 70.5 mm | iPhone 17 · 1 mm wider |
| 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 | Galaxy S25 | Difference |
|---|---|---|---|
| Screen size | 6.3″ | 6.2″ | iPhone 17 · 0.1″ larger |
| Panel | OLED | OLED | Same |
| Resolution | 1206 × 2622 | 1080 × 2340 | Different |
| Pixel density | 460 ppi | 416 ppi | iPhone 17 · 44 ppi denser (11%) |
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 · 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 | Galaxy S25 | Difference |
|---|---|---|---|
| Chipset | Apple A19 | Snapdragon 8 Elite | Different |
| RAM | 8 GB | 12 GBMore | Galaxy S25 · 4 GB more (50%) |
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) | 512 GB | 512 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 | 3,608 | 3,175 | iPhone 17 · 433 higher (14%) |
Data note. Benchmark figures come from mixed sources and test versions. Treat small gaps as noise. | |||
| Geekbench 6 multi‑core | 8,810 | 10,050 | Galaxy S25 · 1,240 higher (14%) |
Data note. Benchmark figures come from mixed sources and test versions. Treat small gaps as noise. | |||

| Spec | iPhone 17 | Galaxy S25 | Difference |
|---|---|---|---|
| Rear cameras | 48 + 48 MP | 50 + 12 + 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 · 6 MP higher‑res (50%) |
| Max video | 4K · 60 fps | 8K · 30 fps | Different |
| Spec | iPhone 17 | Galaxy S25 | Difference |
|---|---|---|---|
| Battery capacity | 3,692 mAh | 4,000 mAhMore | Galaxy S25 · 308 mAh more (8%) |
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 WHigher | 25 W | iPhone 17 · 15 W higher (60%) |
| Wireless charging (rated) | 30 WHigher | 15 W | iPhone 17 · 15 W higher (100%) |
| Reverse wireless charging | No | Yes | Only Galaxy S25 |
| Spec | iPhone 17 | Galaxy S25 | 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 2 | USB 3.2 | Different |
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 |
| 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.
