Display Comparison

The Samsung Galaxy S21 Ultra’s display is a standout, boasting a peak brightness of 1023 nits and an infinite contrast ratio. It’s vibrant, sharp, and excellent for outdoor visibility. The nubia Z30 Pro’s display is also high quality, but lacks the S21 Ultra’s sheer brightness and potentially color accuracy. Both offer high refresh rates for smooth scrolling.

Camera Comparison

The Samsung Galaxy S21 Ultra’s camera system is significantly more versatile and capable, offering incredible zoom capabilities, excellent low-light performance, and consistently high-quality photos and videos. The nubia Z30 Pro’s camera is good, but doesn’t match the S21 Ultra’s overall quality and feature set. Video recording is also a strong point for the S21 Ultra.

Performance

Both phones are powered by flagship processors – the Snapdragon 888 in the nubia Z30 Pro and either the Exynos 2100 or Snapdragon 888 in the S21 Ultra (depending on region). Performance is generally excellent on both, with the slight edge potentially going to the S21 Ultra due to Samsung's software optimization. The nubia Z30 Pro's Cortex-X1 core might offer a slight advantage in single-core tasks.

Battery Life

The nubia Z30 Pro’s 120W charging is a game-changer, allowing for incredibly fast top-ups. The S21 Ultra, while offering decent battery life (rated at 114h endurance), charges much slower at 25W wired. Both phones have adequate battery capacity for a full day of use.

Buying Guide

The ZTE nubia Z30 Pro is ideal for power users who prioritize charging speed and raw performance, and are comfortable with a less established brand. The Samsung Galaxy S21 Ultra is the better choice for those seeking a top-tier camera, a vibrant display, and the reliability of a well-known brand with extensive software updates.

Frequently Asked Questions

❓ Is the nubia Z30 Pro worth buying if I'm not a heavy gamer?
