About ZTE Nubia Z50 Ultra 5G

The ZTE Nubia Z50 Ultra 5G features a 6.8‑inch AM‑OLED panel that delivers vivid colors and sharp detail thanks to its 1116 × 2480 pixel resolution. Measuring 76.3 mm wide, 163.9 mm tall and just 8.3 mm thick, the handset sits comfortably in the hand at 228 grams, offering a sleek profile for daily use.

Under the hood, Google’s Android 13 (Tiramisu) runs on 12 GiB of RAM, providing ample headroom for multitasking and demanding apps. A 5000 mAh battery supplies the power needed to keep the display and 5G connectivity alive throughout the day, while the device supports a single SIM card for straightforward mobile service.

This variant

This model adds 256 GB of internal storage, a specification not detailed in the base model’s description.

It is labeled as the Premium Edition, which separates it from the Standard, Photographer and Top variants of the same device.

Compared with the Standard Edition (also 256 GB) it carries the Premium Edition badge, while the Photographer and Top editions step up to 512 GB and 1 TB respectively.

The other Premium Edition model in the lineup steps up to 512 GB storage, making this the only Premium Edition with the 256 GB configuration.

All versions are built for TD‑LTE networks in China, but this particular combination of storage and edition is unique to this variant.
