Galaxy S27 Ultra vs OPPO Find X10 Pro Max: Future Battle

Build and design

The OPPO is a camera flagship at 6.78 inches, with a triple 200MP camera system, Hasselblad Hi-Res and an optional Teleconverter, and IP66/IP68/IP69 ratings. The S27 Ultra is leaked to keep a similar 6.9-inch front design, with a raised camera island, or Camera Plateau, replacing the floating camera rings, and slimmer bezels at 1.21–1.28mm. Colours tipped are Black, Blue, Light Pink and White, plus a special Violet option.

If you want a proven camera phone today, the OPPO wins. If you want a new camera island and slimmer bezels, the S27 Ultra is a wait-and-see leak. For most buyers, the OPPO is the safer choice in Europe until Samsung announces the S27 Ultra.

Display and benchmarks

The OPPO offers a 6.78-inch AMOLED at 2772 x 1272, with 1–120Hz and up to 3,600 nits. The S27 Ultra is leaked to offer a 6.9-inch display at 1440 x 3120, with a next-generation M16 OLED panel and a second-generation Privacy Display, which should help brightness and power efficiency. For everyday use, both displays are flagship-grade on paper, with the S27 Ultra winning on panel generation only if the leak is confirmed.

On benchmarks, the OPPO uses Dimensity 9600 Pro on 2nm and the S27 Ultra is leaked to use Snapdragon 8 Elite Gen 6 Pro for Galaxy, also on 2nm, so no chip winner is claimed — a controlled side-by-side benchmark between these two phones does not exist, and cross-platform benchmarks are not directly comparable. For sustained performance, the S27 Ultra's cooling is not confirmed, while the OPPO's chip is proven in reviews.

Cameras and video

The OPPO offers triple 200MP cameras — a main at Type 1/1.3 f/1.5 24mm, an ultrawide at 1/1.56 f/2.2 13mm 124°, and a telephoto at 1/1.56 f/2.1 70mm 3x with telemacro — plus a 3.2MP multispectral sensor and a 50MP front camera, with 8K30 and 4K120 on all rear cameras. The S27 Ultra is leaked to offer a triple camera: 200MP ISOCELL HP6 main, a 50MP ultrawide and a 50MP 5x telephoto, plus a 16MP selfie camera. On paper, the OPPO wins on triple 200MP and telemacro, while the Samsung wins on 5x telephoto.

No controlled side-by-side camera test between these two phones exists, so no photo winner is claimed beyond the leaked hardware gap. If you shoot zoom often, the Samsung's 5x telephoto is stronger on paper. If you shoot at 1x and want Hasselblad colour, the OPPO's triple 200MP system is stronger on paper. For video, the OPPO's 8K30 and 4K120 on all rear cameras are stronger on paper.

Battery, software and price

Battery is where the OPPO wins on paper in Europe, with 7,150mAh and 80W wired and 50W wireless charging, versus the S27 Ultra's leaked rated 5,534mAh, typically around 5,700mAh, with 60W wired and 25W wireless charging leaked. For most users, the OPPO will last longer on paper in Europe, while the Samsung's battery is leaked only. Charging is faster on the OPPO on paper, though real-world charging should be checked in reviews.

Software is leaked as One UI 9.5 on Android 17 with 7 years of OS upgrades for the S27 Ultra, while the OPPO runs ColorOS 17, with IP66/IP68/IP69. In Europe, the OPPO is on sale from €1,799 for 12GB/512GB, while the S27 Ultra has no announced price — a price hike is tipped, but no figure is confirmed. In the US, neither is officially sold.

Verdict

Buy the OPPO Find X10 Pro Max if you want a camera phone in Europe from €1,799 today. Wait for the Galaxy S27 Ultra if you want its leaked 5,700mAh battery, M16 display and triple-camera setup, and check Samsung's announcement in early 2027. For most European buyers, the OPPO is the only choice today — the S27 Ultra is a leak-based wait-and-see.
