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‑S908U1 variant upgrades the base model’s memory to 12 GiB of RAM and adds a modest 1 gram increase in weight to 229 g. It also provides 256 GB of internal storage and is tuned for US‑market UW TD‑LTE 5G networks, a configuration not detailed in the base description.

Compared with the other listed versions, this model stands out by retaining a single SIM slot while most US UW alternatives offer dual SIM capability. Its 12 GiB RAM paired with 256 GB storage situates it between the lower‑end 128 GB/8 GiB US UW model and the higher‑end 1 TB/12 GiB US UW model, and it differs from global or EU editions by being a US‑specific release with UW TD‑LTE support.
