About Samsung Galaxy S22 Ultra

The Samsung Galaxy S22 Ultra presents a sleek silhouette measuring 77.9 mm wide, 163.3 mm tall and just 8.9 mm thick, weighing in at 228 grams. Its front is dominated by a 6.81‑inch Color AM‑OLED panel that delivers a sharp 1440 × 3088 resolution, offering vivid colours and deep contrast for everything from scrolling social feeds to watching high‑definition video. The device keeps things simple with a single SIM slot, catering to users who prefer a streamlined connectivity option.

Under the hood, the phone runs Google Android 12 (S) and is equipped with 8 GiB of RAM, providing ample headroom for multitasking and demanding apps. Power comes from a 5000 mAh battery that supports wired charging at up to 15 watts, ensuring you can top up the cell relatively quickly when needed. Together, these specifications position the Galaxy S22 Ultra as a capable flagship that balances a large, high‑resolution display with solid performance and endurance.

This variant

The Samsung SM‑S908U model steps up the memory to 12 GiB of RAM, double the base model’s 8 GiB, while keeping the same 5000 mAh battery and 15 W wired charging. It also ships with 256 GB of internal storage, a step up from the base model’s unspecified capacity, and is marginally heavier at 229 grams.

Unlike most of the U.S.‑market UW‑enabled siblings that list a dual‑SIM tray, this particular SM‑S908U/SM‑S908R4 variant retains a single‑SIM slot, matching the base model’s configuration. It is tuned for the U.S. TD‑LTE UW bands and is carrier‑locked to the SM‑S908R4 version, distinguishing it from the global or other carrier‑specific SKUs in the list.
