Apple iPhone 17 Pro VS Samsung Galaxy S25 Ultra

Both phones share the same IP68 waterproof rating and identical operating temperature ranges, so neither has an edge in environmental protection. The real design story here is about form factor. The iPhone 17 Pro is notably more compact — 150 mm tall and 71.9 mm wide versus the S25 Ultra's 162.8 mm height and 77.6 mm width — resulting in a total volume of 94.37 cm³ compared to the S25 Ultra's 103.59 cm³. In practical terms, the iPhone 17 Pro fits more naturally in smaller hands and tighter pockets.

Weight and thickness tell a split story. The iPhone 17 Pro is the lighter device at 206 g versus 218 g for the S25 Ultra — a 12 g difference that becomes noticeable during extended one-handed use or when holding the phone up for prolonged periods. The S25 Ultra, however, is the slimmer handset at 8.2 mm thick compared to the iPhone 17 Pro's 8.75 mm, giving it a sleeker profile despite its larger footprint.

Overall, the iPhone 17 Pro holds a meaningful edge for users who prioritize ergonomics and portability — it is lighter and substantially more compact. The S25 Ultra trades that compactness for a larger canvas, which suits users who value screen real estate and can accept a bigger, heavier device. Neither phone is ruggedized, so durability beyond the shared IP68 rating is not a differentiator here.

The screen size gap between these two phones is significant: the S25 Ultra's 6.9″ panel versus the iPhone 17 Pro's 6.3″ display means noticeably more usable area for reading, multitasking, and media consumption. The S25 Ultra also wins on raw sharpness, with a pixel density of 498 ppi compared to 460 ppi — both are well beyond the threshold where individual pixels become invisible to the naked eye, but the Ultra's advantage is measurable under close inspection. More impactful in daily use is brightness: the S25 Ultra's 2600 nits typical output dwarfs the iPhone 17 Pro's 1000 nits, translating to dramatically better legibility in direct sunlight.

Touch responsiveness is another area where the S25 Ultra differentiates itself, offering a 240Hz touch sampling rate versus 120Hz on the iPhone 17 Pro. This means the S25 Ultra registers finger input twice as frequently, which benefits fast-paced gaming and stylus use more than everyday browsing. On the HDR front, the two phones diverge rather than stack up: the iPhone 17 Pro supports Dolby Vision while the S25 Ultra does not, whereas the S25 Ultra covers HDR10+ which the iPhone 17 Pro lacks. For most users this distinction is content-ecosystem-dependent — streaming platforms and video apps tend to favor one standard or the other. The S25 Ultra also ships with branded damage-resistant glass, an advantage the iPhone 17 Pro's specs do not match in this dataset.

The S25 Ultra holds a clear overall edge in this category. Its advantages in screen size, peak brightness, pixel density, touch sampling rate, and glass protection collectively add up to a more capable display — particularly for outdoor use and power users. The iPhone 17 Pro counters with Dolby Vision support, which matters in specific content workflows, but that single differentiator does not close the gap.

Single-core performance is where the iPhone 17 Pro's Apple A19 Pro chip makes its dominance unmistakable. Its Geekbench 6 single-core score of 3,781 towers over the S25 Ultra's 3,057 — a gap of roughly 24% that directly reflects how snappy the iPhone feels in everyday tasks like app launches, UI interactions, and workloads that cannot be parallelized. The overall AnTuTu score reinforces this: 2,707,681 versus 2,207,809 for the Snapdragon 8 Elite, a lead of roughly 23%. For general responsiveness, the A19 Pro is the faster chip by a meaningful margin.

The picture shifts considerably when looking at GPU and memory architecture. The S25 Ultra's Adreno 830 packs 1,536 shading units against the iPhone 17 Pro's 128 — an enormous structural difference that gives the S25 Ultra a fundamentally larger graphics pipeline for compute-heavy and GPU-parallel workloads. The S25 Ultra also leads in memory bandwidth at 85.1 GB/s versus 78.8 GB/s, and its RAM runs at a faster 5,300 MHz. Critically, the S25 Ultra supports up to 24 GB of RAM — double the iPhone 17 Pro's 12 GB ceiling — along with ECC memory for error correction, features that matter most for sustained multitasking, large AI model inference, and pro-grade workloads. Its 8.2W TDP versus the iPhone's 10W also suggests the Snapdragon achieves its performance more efficiently under sustained load.

This group does not have a single clean winner — it depends entirely on use case. The iPhone 17 Pro is the faster chip for single-threaded and everyday performance. The S25 Ultra counters with a vastly wider GPU, more headroom in memory capacity and bandwidth, and greater multi-core throughput, making it better suited for graphics-intensive applications and heavy parallel workloads. Power users running demanding apps will find more ceiling on the S25 Ultra; users who prize fluid, low-latency everyday performance will favor the A19 Pro.

The rear camera systems reveal fundamentally different philosophies. The S25 Ultra deploys a four-lens array headlined by a 200 MP primary sensor — a resolution that enables aggressive cropping and exceptional detail retention in well-lit scenes. By contrast, the iPhone 17 Pro runs a triple-lens setup where all three cameras are fixed at 48 MP, prioritizing consistency across focal lengths over a single dominant sensor. The S25 Ultra's primary pixel size of 0.6 µm is smaller than any of the iPhone 17 Pro's sensors, with the Pro's main camera offering 1.22 µm pixels — larger pixels generally capture more light per photosite, which matters in low-light conditions. The iPhone 17 Pro also starts wider, with a minimum focal length of 13 mm versus 24 mm on the S25 Ultra, giving it a more versatile ultra-wide reach. The S25 Ultra counters with 5x optical zoom against the iPhone's 4x, and its four-lens system covers more discrete focal lengths overall.

For video, the iPhone 17 Pro pulls ahead in one notable way: it supports 4K at 120 fps recording, versus the S25 Ultra's 8K at 30 fps ceiling. The iPhone also retains its Dolby Vision recording capability, absent on the S25 Ultra, which is a meaningful differentiator for anyone editing in a Dolby Vision-compatible workflow. The S25 Ultra's 8K capture, on the other hand, offers an enormous resolution buffer for reframing or cropping footage in post-production. On the front camera, the iPhone 17 Pro's 18 MP selfie sensor outresolves the S25 Ultra's 12 MP, and its wider f/1.9 aperture versus f/2.2 on the S25 Ultra means better low-light selfie performance.

This is a close category with no universal winner. The S25 Ultra is the stronger choice for photographers who want maximum resolution, more optical zoom range, and 8K video capture. The iPhone 17 Pro is the better fit for videographers who need high-frame-rate 4K, Dolby Vision recording, and a wider ultra-wide starting point. The right call depends entirely on whether stills resolution or video versatility matters more to the user.

On shared ground, both phones cover the essentials well — dark mode, focus modes, customizable notifications, battery health checks, Picture-in-Picture, widgets, offline voice recognition, and robust privacy controls including camera/microphone permissions, app tracking blocks, and cross-site tracking prevention. For most users, this common feature floor is sufficient for daily use. The divergence, however, lies in flexibility and openness. The S25 Ultra supports split-screen multitasking, multi-user accounts, dynamic theming, and can function as a PC replacement — capabilities the iPhone 17 Pro entirely lacks. These are not minor omissions; split screen and desktop mode meaningfully expand what a phone can do as a productivity device.

The iPhone 17 Pro's key advantage in this category is its update model. It receives direct OS updates from Apple, meaning new software versions arrive immediately without carrier or manufacturer delays. The S25 Ultra does not share this trait, as Android updates pass through an additional layer before reaching the device. The iPhone also offers Mail Privacy Protection, a privacy feature absent on the S25 Ultra, which prevents email senders from tracking whether and when a message was opened. These are meaningful wins for privacy-conscious and security-focused users.

Taken as a whole, the S25 Ultra holds the broader feature advantage in this group, with more customization options, superior multitasking capabilities, multi-user support, and desktop use — all of which cater to power users who want their phone to do more. The iPhone 17 Pro counters with a tighter, more privacy-centric experience and a faster, more predictable update pipeline, which will matter more to users who prioritize security and simplicity over flexibility.

Despite the S25 Ultra carrying a notably larger 5,000 mAh battery versus the iPhone 17 Pro's 4,252 mAh, the real-world battery life figures tell a surprising story: the iPhone 17 Pro lasts 33 hours compared to the S25 Ultra's 31 hours. This means the A19 Pro chip's efficiency effectively neutralizes the S25 Ultra's capacity advantage, squeezing more runtime out of fewer milliamp-hours. For users, the practical takeaway is that both phones are closely matched in longevity, and the iPhone 17 Pro edges ahead on endurance despite the smaller cell.

Charging is where the two phones split in different directions. The S25 Ultra is faster on wired charging at 45W versus 40W, a modest but real difference that shaves a few minutes off a full charge cycle. The iPhone 17 Pro flips the advantage on wireless charging, offering 30W wirelessly compared to the S25 Ultra's 15W — double the wireless speed, which is a meaningful gap for users who rely on a wireless pad as their primary charging method. The S25 Ultra adds reverse wireless charging, a feature the iPhone 17 Pro lacks entirely, allowing it to top up accessories like earbuds or a smartwatch directly from the phone's back.

Neither phone ships with a charger in the box, so both require a separate purchase regardless. Overall, this group is closely contested: the iPhone 17 Pro leads on battery life and wireless charging speed, while the S25 Ultra counters with a larger capacity, faster wired charging, and the added utility of reverse wireless charging. Users who charge wirelessly will find the iPhone 17 Pro more capable; those who use wired charging or want to power accessories on the go will lean toward the S25 Ultra.

Both phones share the same hardware baseline here — stereo speakers, no 3.5mm headphone jack, and three microphones — so the core listening and call-capture experience is structurally identical on paper. The meaningful separation comes entirely from Bluetooth audio codec support. The S25 Ultra supports aptX, aptX HD, and LDAC, while the iPhone 17 Pro supports none of these. For wireless audio enthusiasts, this is a significant gap: LDAC in particular transmits up to three times the data of standard Bluetooth audio, delivering near-lossless quality to compatible headphones and speakers.

In practical terms, the iPhone 17 Pro is limited to standard Bluetooth audio codecs when paired with wireless headphones. Users with high-end LDAC-compatible or aptX HD-compatible headphones will only unlock their full audio fidelity potential on the S25 Ultra. Neither phone supports aptX Adaptive or aptX Lossless, so the S25 Ultra's codec advantage, while real, has a ceiling — but it is still a ceiling the iPhone 17 Pro cannot reach at all based on these specs.

The S25 Ultra holds a clear edge in this category for anyone who takes wireless audio quality seriously. The three-microphone setup and stereo speakers leave both phones evenly matched for calls and speakerphone use, but the S25 Ultra's LDAC and aptX HD support makes it the stronger choice for users invested in high-resolution wireless audio.

Wireless connectivity is nearly identical between these two phones — both support Wi-Fi 7, 5G, NFC, USB 3.2 Type-C, and GPS with Galileo — so neither holds a structural advantage in raw network capability. Where they diverge is in Bluetooth: the iPhone 17 Pro ships with the newer Bluetooth 6 versus the S25 Ultra's Bluetooth 5.4, which translates to improved connection stability, lower latency, and better handling of multiple simultaneous audio devices. The iPhone 17 Pro also supports only a single physical SIM plus one eSIM, while the S25 Ultra accommodates 2 SIMs and 2 eSIMs — a tangible advantage for frequent travelers or users who juggle work and personal lines on one device.

The unique features each phone brings to the table are notably different in character. The iPhone 17 Pro offers emergency SOS via satellite and crash detection — safety-oriented capabilities the S25 Ultra entirely lacks — alongside 3D facial recognition and an infrared sensor. The S25 Ultra answers with a fingerprint scanner, a built-in stylus, and ANT+ support for fitness accessory connectivity. The stylus inclusion is particularly significant for productivity and note-taking use cases, representing a hardware capability the iPhone 17 Pro simply cannot replicate.

This category ends as a meaningful split rather than a clean win for either side. The iPhone 17 Pro's edge in Bluetooth 6 and its satellite safety features make it the stronger choice for users who prioritize connectivity precision and emergency preparedness. The S25 Ultra's dual-SIM flexibility, fingerprint scanner, integrated stylus, and ANT+ support cater to power users, travelers, and anyone who values a broader physical feature set. Which phone wins here depends entirely on which of these capabilities aligns with the user's daily needs.

The miscellaneous specs for these two phones are a complete match across every data point provided. Both feature a video light, neither uses sapphire glass, neither has a curved or e-paper display. There is nothing in this group that separates them.

This is an unambiguous tie. No advantage exists for either the Apple iPhone 17 Pro or the Samsung Galaxy S25 Ultra based solely on the specs provided here, and users should look to other specification groups to inform their decision.
