About Sony Xperia 5 III 5G

The Sony Xperia 5 III 5G presents a compact yet vibrant form factor, measuring 68 mm wide, 157 mm tall and just 8.2 mm thick while weighing in at 168 grams. Its 6.1‑inch AM‑OLED panel delivers a full‑HD+ resolution of 1080 by 2520 pixels, offering sharp colors and deep contrast typical of the technology. Powered by Android 11, the device is equipped with 8 GiB of RAM, providing ample memory for multitasking and app performance. A single SIM slot keeps the connectivity straightforward, and the 4500 mAh battery aims to support a full day of use despite the phone’s slender profile. Together, these specifications position the Xperia 5 III 5G as a refined option for users who value a high‑quality display and solid performance in a hand‑friendly size.

This variant

This variant is the Japanese TD‑LTE model equipped with 128 GB of internal storage and sold under the Docomo SO‑53B designation.

Compared with the dual‑SIM 256 GB JP version (XQ‑BQ42) it provides half the storage, while differing from the other JP 128 GB models (SOG05, A103SO) by its carrier‑specific model number. Against the APAC and NA dual‑SIM 256 GB editions it remains a Japan‑specific model with less onboard storage.
