About Samsung Galaxy S23 Ultra

The Samsung Galaxy S23 Ultra presents a sleek, premium feel with its dimensions of 78.1 mm wide, 163.4 mm tall and 8.9 mm thick, weighing in at 234 grams. Its front is dominated by a 6.81‑inch AM‑OLED panel that delivers a sharp 1440 × 3088 resolution, offering vivid colours and deep contrast for everything from media consumption to detailed productivity work. The device retains a single‑SIM configuration, keeping the design clean and straightforward.

Under the surface, the phone runs Google Android 13 (Tiramisu) and is equipped with 12 GiB of RAM, providing ample headroom for multitasking and demanding applications. A 5000 mAh battery powers the device, supporting wired charging at up to 15 watts to keep you going through the day. These core specifications position the Galaxy S23 Ultra as a high‑end flagship that balances a large, high‑resolution display with solid performance and endurance.
