Compare documented iPhone 17 Pro and Galaxy S26 Ultra features, size and ecosystem requirements without fabricated performance or battery measurements.
The iPhone 17 Pro and Galaxy S26 Ultra offer different sizes and platform features. This comparison uses their published documentation. We removed the previous claims that iPhoneExtra performed drop, camera, benchmark and battery tests.
Correction, September 5, 2026: corrected compatibility and specification claims using the sources below. This is a research-based assessment, not a firsthand product test.
Confirmed hardware
Use Apple’s specifications and Samsung’s launch specification table as the source for the exact configurations.
| Feature | iPhone 17 Pro | Galaxy S26 Ultra |
|---|
| Display class | 6.3-inch | 6.9-inch |
| Chip | A19 Pro | Snapdragon 8 Elite Gen 5 for Galaxy |
| Rear cameras | 48MP Main, Ultra Wide and 4x Telephoto | 200MP Wide, 50MP Ultra Wide, 50MP 5x and 10MP 3x Telephoto |
| Front camera | 18MP Center Stage | 12MP |
| Distinct input | Camera Control | Built-in S Pen |
Camera quality is not settled by this table
More megapixels or more cameras do not automatically mean better images. Compare the focal lengths, video formats and functions you use, then look for documented sample comparisons. The earlier claim of 40% more low-light detail had no supporting measurement and has been withdrawn.
The 17 Pro’s optical-quality 8x option is not an additional physical 8x lens. The older 16 Pro also has a 48MP Ultra Wide and Camera Control; see the 17 Pro versus 16 Pro comparison.
Battery and charging
Samsung documents 60W charging with its compatible adapter, not the 45W limit previously listed here. Apple documents its own adapter and cable conditions. Neither a wattage number nor the two companies’ separately measured runtime figures establish a matched real-world battery winner.
The previous screen-on times, temperature differences and benchmark scores were unsupported. We have removed them rather than presenting them as measured evidence.
Software and accessories
The iPhone launched with iOS 26, not “iOS 20.” Samsung’s launch documentation names Android 16 and One UI 8.5. Check the current software offered on each device and the language, region and account requirements of the specific AI features you want.
Apple Watch requires a compatible iPhone. Apple’s AirPods specifications explain that they can still function as Bluetooth headphones with non-Apple devices, although features can be limited. Switching to Galaxy does not automatically require replacing AirPods. Review the migration requirements for your messages, authentication apps and purchased software before switching.
Which should you choose?
Consider iPhone if its smaller display size and compatibility with your existing Apple devices matter most. Consider Galaxy if you want its larger screen, S Pen or specific Android workflows. Compare the actual storage tier, local price and return terms.
A working current phone may already meet your needs. This article does not declare a universal camera, performance or battery winner without comparable evidence.
