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.

This variant

This China‑market model carries 8 GiB of RAM and a 256 GB storage configuration, weighing in at 233 g.

It is labelled as a Standard Edition for the TD‑LTE CN network and lacks the UW, Premium or BMW M badges found on many other versions.

Compared with the other listed Galaxy S23 Ultra variants, it is the sole device destined for China, while the rest target the United States, Canada, Korea, Japan or global markets.

While several alternatives offer 512 GB or 1 TB of storage and 12 GiB of RAM, this version pairs 256 GB with 8 GiB, and unlike the dual‑SIM SM‑S918B/DS it retains a single‑SIM setup.

Its 233 g mass makes it the lightest of the listed models, and its TD‑LTE CN radio distinguishes it from the TD‑LTE US/CA/KR/JP units elsewhere.
