Samsung Galaxy S25 Ultra vs iPhone 16 Pro Max

Camera quality is the most heavily weighted criterion because the camera is the feature most people use every day on their smartphone. This comparison considers photo quality, video recording, low-light performance and zoom versatility.

The iPhone 16 Pro Max scores 10/10. Its 48MP main sensor captures excellent detail with natural colour reproduction. The standout upgrade is the new 48MP ultrawide, which captures four times more detail than its predecessor. Where the iPhone truly separates itself is video recording. ProRes capture at up to 4K 120fps delivers footage that professionals can edit alongside cinema camera material. Cinematic Mode and Action Mode remain unmatched in the smartphone space. The Camera Control button provides a dedicated physical interface for adjusting focus, zoom and exposure without touching the screen.

The Samsung Galaxy S25 Ultra scores 9/10. Its 200MP main sensor captures extraordinary detail in still photos, producing images that can be cropped aggressively without losing clarity. The 50MP 5x telephoto is the most capable zoom camera on any smartphone, delivering sharp images at distances where other phones produce soft results. The 10MP 3x telephoto adds a useful mid-range option. For still photography enthusiasts, the Samsung's camera hardware is arguably superior. Video recording is very good but does not match the iPhone's ProRes pipeline and colour consistency across all lenses.

Performance is rated critical because processing power directly affects how responsive the phone feels during daily use and how long it remains capable as apps become more demanding.

The iPhone 16 Pro Max scores 10/10. The A18 Pro chip sets the benchmark for mobile processing. In single-core tasks, which affect everyday app responsiveness, it leads every Android processor. In multi-core and GPU workloads, it matches or exceeds the Snapdragon 8 Elite. The critical differentiator is thermal management. During extended gaming, video rendering or multitasking, the iPhone maintains its peak performance level more consistently than any competitor.

The Samsung Galaxy S25 Ultra scores 9/10. The Snapdragon 8 Elite for Galaxy is an exceptional processor that handles every current app and game with ease. In GPU-intensive benchmarks, it trades blows with the A18 Pro. However, under sustained heavy load, the chip can throttle slightly due to thermal constraints. In practical daily use, the difference is minimal and most users will never notice it. The 12 GB of RAM gives the Samsung an advantage in multitasking and keeping apps in memory.

AI features have become increasingly important as both Samsung and Apple integrate intelligent capabilities directly into the smartphone experience. On-device AI affects daily tasks from photo editing to communication.

The Samsung Galaxy S25 Ultra scores 9/10. Galaxy AI is the most comprehensive on-device AI suite available. Circle to Search lets you identify anything on screen with a gesture. Real-time call translation works across languages without an internet connection. AI-powered photo editing can remove objects, expand backgrounds and enhance images with impressive accuracy. Transcript summaries, chat translation and smart formatting tools add genuine productivity value. Samsung has iterated on these features through multiple generations, and the S25 Ultra represents the most polished version yet.

The iPhone 16 Pro Max scores 8/10. Apple Intelligence brings capable AI features including writing tools, smart summaries, a more conversational Siri and generative image creation. However, Apple Intelligence arrived later than Galaxy AI and is not yet available in all countries and languages. When available, the features are well-integrated into iOS, but the breadth of Samsung's AI toolkit currently gives the Galaxy S25 Ultra a meaningful advantage in this category.

Battery life is rated important because a phone that cannot last a full day undermines everything else it does well. Both phones target all-day battery life, but their approaches and results differ.

The Samsung Galaxy S25 Ultra scores 9/10. Its 5,000 mAh battery typically delivers 13 to 15 hours of screen-on time, making it one of the longest-lasting flagship phones available. The efficient Dynamic AMOLED 2X display with adaptive refresh rate helps extend battery life when displaying static content. Charging supports 45W wired and 15W wireless, with a full charge from empty taking approximately 65 minutes on a wired charger.

The iPhone 16 Pro Max scores 8/10. Its 4,685 mAh battery delivers 12 to 14 hours of screen-on time, which is excellent but slightly behind the Samsung. Apple's efficient A18 Pro chip and iOS power management help maximise the smaller cell. Charging supports 27W wired via USB-C and 25W MagSafe wireless. Both phones comfortably last a full day for most users, but the Samsung provides a more comfortable margin for heavy users who stream video or game extensively.

Both phones feature 6.9-inch 120Hz displays, but Samsung's panel technology holds a notable advantage in brightness and vividity.

The Samsung Galaxy S25 Ultra scores 10/10 for display quality. Its Dynamic AMOLED 2X panel reaches approximately 2,600 nits of peak brightness, making it the brightest smartphone display available. Outdoor visibility in direct sunlight is excellent. Colour accuracy is outstanding, with support for a wide colour gamut and adaptive colour temperature. The S Pen adds a unique interaction layer, with 4,096 levels of pressure sensitivity for precise handwriting and drawing.

The iPhone 16 Pro Max scores 9/10. Its Super Retina XDR display with ProMotion is sharp, colour-accurate and smooth at 120Hz. Peak brightness reaches approximately 2,000 nits, which is excellent but noticeably lower than the Samsung's panel in direct sunlight. The always-on display implementation is refined and battery-efficient. This is a strong display by any measure, but Samsung's panel technology maintains a clear lead in brightness.

Both phones score 8/10 for value. At these price points, neither represents affordable purchasing, but both deliver flagship experiences that justify their premium positioning.

The iPhone 16 Pro Max starts at £1,199, which is £100 less than the Samsung Galaxy S25 Ultra's £1,299 entry point. The iPhone also holds an advantage in resale value. After two years, iPhones typically retain 50 to 60% of their original price, while Samsung flagships retain 35 to 45%. This makes the total cost of ownership more favourable for the iPhone over a typical upgrade cycle.

The Samsung Galaxy S25 Ultra counters by including the S Pen, a larger battery, more RAM (12 GB vs 8 GB) and the most advanced AI feature suite at its price point. If you plan to use the phone for its full lifespan and value the additional features, the Samsung's higher price is justified. Both phones represent the pinnacle of what smartphones can do in 2026.
