About Sony Xperia 1 IV 5G
The Sony Xperia 1 IV 5G presents a sleek, tall form factor measuring 71 mm wide, 165 mm tall and just 8.2 mm thick, weighing in at a modest 185 grams. Its front is dominated by a 6.5‑inch AMOLED panel that delivers an impressive 1644 by 3840 pixel resolution, offering sharp detail and vibrant colours for media consumption and productivity alike. The device supports a single SIM slot, keeping the design streamlined while still providing 5G connectivity for fast mobile data.
Under the hood, the phone runs Google Android 12 out of the box and is equipped with a generous 16 GiB of RAM, ensuring smooth multitasking and responsive performance across apps and games. Powering the experience is a 5000 mAh battery, aimed at delivering endurance through a full day of use. Together, these specifications position the Xperia 1 IV 5G as a high‑end option that combines a premium display with substantial memory and battery capacity.
This variant ships with Android 12 (S) instead of the base model’s plain Android 12, steps down to 12 GiB of RAM from the base’s 16 GiB, and tips the scales at 187 g – two grams heavier than the base’s 185 g. It also adds 256 GB of internal storage and is tuned for the Japanese market with UW TD‑LTE support, details absent from the base description.
Compared to the other Xperia 1 IV 5G variants, it is the sole model that uses a single SIM slot while the others offer dual‑SIM capability. Unlike the North‑American UW Dual SIM 512 GB unit, it halves the storage to 256 GB, and unlike the Japanese Dual SIM 512 GB model it cuts the RAM in half. It shares the 256 GB capacity and 12 GiB RAM of the Japanese UW Dual SIM 256 GB model but differs in that model’s dual‑SIM configuration.
