About Sony Xperia XA1 Ultra
The Sony Xperia XA1 Ultra presents itself as a sleek, single‑SIM smartphone wrapped in a compact frame measuring 79 mm wide, 165 mm tall and just 8.1 mm thick, tipping the scales at 188 grams. At its front lies a 6‑inch TN‑TFT LCD panel that delivers a crisp Full HD experience with a resolution of 1080 by 1920 pixels, offering vivid colours and sharp detail for everyday media consumption. Powered by Android 7.0 Nougat out of the box, the device is equipped with 4 gigabytes of RAM, providing smooth multitasking and responsive performance for apps and games alike.
Under the hood, a 2700 mAh battery fuels the handset, aiming to keep you connected through a typical day of use. The combination of its modest dimensions, lightweight build and efficient battery capacity makes the Xperia XA1 Ultra a pocket‑friendly option for those who value a large display without excessive bulk. With a single SIM slot, the phone focuses on straightforward connectivity, staying true to Sony’s design ethos of balancing form and function.
This variant is branded as the Sony Redwood SS model and carries an LTE‑A modem, targeting the EMEA market under the identifiers G3221/SM21.
It differs from the base model by providing LTE‑A connectivity rather than the unspecified radio of the generic version, and from the TD‑LTE and dual‑SIM editions by its EMEA focus and LTE‑A specification.
