Product Overview

The Samsung Galaxy S23 Ultra combines a built‑in S Pen, a 200 MP quad camera, and a large 6.8‑inch QHD+ Dynamic AMOLED 2X display in a single device. It’s powered by the Snapdragon 8 Gen 2 for Galaxy processor, which is optimised for gaming, multi‑tasking, and AI‑driven photo processing. The 5,000 mAh battery provides all‑day endurance, and the titanium‑reinforced frame adds durability. The phone runs One UI 6.1 on Android 14 and ships with Galaxy AI features including Circle to Search, Note Assist, and Generative Edit. It’s available in Phantom Black, Green, Cream, and Lavender.

Key Features

• 200 MP Quad Camera: The main 200 MP sensor uses pixel binning for detailed 12 MP or 50 MP photos. A 12 MP ultra‑wide, a 10 MP 3x telephoto, and a 10 MP 10x periscope telephoto complete the system. Optical stabilization (OIS) on both telephoto lenses keeps long‑range shots sharp.

• Galaxy AI (One UI 6.1): Circle to Search (long‑press the Home button and draw around anything on screen), Live Translate (real‑time call and text translation), Note Assist (auto‑format and summarize Samsung Notes), and Generative Edit (resize or remove objects in photos).
• 5,000 mAh Battery & 45 W Charging: Supports 45 W wired USB‑C PD fast charging, 15 W wireless charging, and 4.5 W Wireless PowerShare. A full charge takes about 65 minutes with a 45 W charger (sold separately).
