Best AI Features 2026: iPhone vs Galaxy vs OPPO Compared

Build and design

iPhone is a slab at 6.3 inches, with a Super Retina XDR display at 2622 x 1206, 120Hz and Ceramic Shield 2, and iOS 27. Samsung is a larger slab at 6.9 inches, with a QHD+ Dynamic AMOLED 2X display at 120Hz, Privacy Display and a built-in S Pen. OPPO is a slab at 6.59 inches, with a LTPO display at 2768 x 1272, 1–120Hz and up to 3,600 nits local peak, and IP66/IP68/IP69 ratings. All three feel premium, with Samsung's S Pen the most distinctive productivity feature.

If you want the simplest assistant workflow, iPhone wins. If you want Galaxy AI and DeX, Samsung wins. For most buyers, iPhone and Samsung are the safer choices in the US and Europe, unless camera is a priority.

Display and benchmarks

iPhone offers a 6.3-inch Super Retina XDR display at 2622 x 1206, with 120Hz, up to 3,000 nits peak and Ceramic Shield 2. Samsung offers a 6.9-inch QHD+ Dynamic AMOLED 2X display at 120Hz, with up to 2,600 nits and a Privacy Display. OPPO offers a 6.59-inch LTPO display at 2768 x 1272, with 1–120Hz and 144Hz in games, and up to 3,600 nits local peak. For everyday use, all three are flagship-grade, with iPhone's display the most colour-accurate in reviews. For gaming, OPPO wins on refresh rate in games.

On benchmarks, iPhone uses A20 Pro on 2nm with a C2 modem, Samsung uses Snapdragon 8 Elite Gen 5 for Galaxy, and OPPO uses Dimensity 9600M on 3nm. No controlled side-by-side benchmark between all three phones was reviewed, so no speed winner is claimed beyond the chip generation. For AI processing, all three should handle on-device AI in normal use, though exact AI workloads were not tested side by side.

Cameras and video

iPhone offers triple 48MP cameras — a Fusion main with variable aperture, an ultrawide at f/2.2 and a telephoto at f/2.8 — plus an 18MP front camera at f/1.9 with Centre Stage. Samsung offers a quad camera: 200MP main at f/1.4 and 1/1.3-inch, a 50MP ultrawide, a 50MP 5x telephoto and a 10MP 3x telephoto, plus a 12MP front camera. OPPO offers dual 200MP Hasselblad cameras — a main at 1/1.4-inch f/1.6 and a periscope telephoto at 1/1.56-inch f/2.6, 65mm, 2.8x — plus a 50MP ultrawide at 1/2.75-inch f/2.0 and a 50MP front camera.

No controlled side-by-side camera AI test between all three phones was reviewed, so no photo winner is claimed beyond the hardware gap. If you shoot zoom often, Samsung's dual telephoto is stronger on paper. If you shoot at 1x and want Hasselblad colour, OPPO is stronger on paper. If you shoot for social and editing often, iPhone's ecosystem is stronger in practice. For everyday photos at 1x, all three should be close, despite the megapixel gap.

Battery, software and price

Battery is where OPPO wins on paper in Europe, with 7,150mAh and 80W wired and 50W wireless charging, though other listings give 8,000mAh in other regions — flag the regional difference. Samsung is second on paper, with 5,000mAh and 60W wired charging and up to 31 hours of video in Samsung's rating. iPhone is third on paper, with Apple not disclosing mAh and claiming up to 36 hours of video playback in one listing.

Software is iOS 27 for iPhone, with Siri AI varying by region and EU/China caveats, One UI 8.5 on Android 16 for Samsung, with Galaxy AI and DeX and security updates listed until 28 February 2033 in one spec source, and ColorOS 17 on Android 17 for OPPO. In the US and Europe, iPhone and Samsung are on sale today from $1,199 and $1,399.99 in the US, while OPPO is €1,300 in Europe — OPPO is not officially sold in the US.

Verdict

Buy the iPhone 18 Pro if you want the simplest AI workflow in the US from $1,199 or in Europe from €1,449 today. Buy the Galaxy S26 Ultra if you want Galaxy AI, S Pen and DeX in the US from $1,399.99 or in Europe from €1,550 today. Buy the OPPO Find X10 if you want Hasselblad camera AI in Europe from €1,300. For most US and Europe buyers, iPhone and Samsung are the only choices today — OPPO is Europe-only.
