ZTE Axon 20 5G Extreme

  • Unique under-display camera technology
  • More affordable price point
  • Fast 30W charging with QC4 support

  • Less powerful Snapdragon 765G chipset
  • Potentially compromised front camera image quality
  • Display uniformity may be affected by under-display camera

Sony Xperia 5 III

  • Flagship Snapdragon 888 performance
  • Bright and vibrant display
  • Sony’s Alpha camera expertise and software optimizations

  • Significantly higher price
  • May experience thermal throttling under sustained load
  • Slightly slower charging speed compared to Axon 20

Display Comparison

The Sony Xperia 5 III boasts a measured peak brightness of 590 nits, significantly brighter than what’s likely available on the Axon 20 5G Extreme (data unavailable, but typically lower in this price bracket). While both offer an 'infinite' contrast ratio, the Xperia 5 III’s display is likely to deliver a more vibrant and visible experience in direct sunlight. The Axon 20’s key differentiator is its under-display camera, sacrificing some display uniformity for a truly bezel-less front. The Xperia 5 III’s more traditional display offers a cleaner viewing experience, but lacks the novelty of the Axon 20’s implementation.

Camera Comparison

Both devices are advertised as capable photo and video devices, but the specifics differ. The Xperia 5 III benefits from Sony’s Alpha camera expertise, likely incorporating advanced image processing algorithms and potentially larger sensor sizes (data unavailable for both). The Axon 20’s under-display camera is a technological marvel, but image quality is inevitably compromised compared to a traditional front-facing camera. The Xperia 5 III’s rear camera system, while details are missing, will likely offer superior dynamic range, low-light performance, and video stabilization due to the more powerful ISP within the Snapdragon 888.

Performance

The core difference lies in the chipsets: the ZTE Axon 20 5G Extreme utilizes the Qualcomm SM7250 Snapdragon 765G (7nm), while the Sony Xperia 5 III is powered by the flagship Qualcomm SM8350 Snapdragon 888 (5nm). The 5nm process node of the 888 offers superior power efficiency and thermal performance compared to the 7nm 765G. The Xperia 5 III’s CPU, featuring a Cortex-X1 prime core, will demonstrably outperform the Axon 20’s Kryo 475 Prime in single-core tasks and overall responsiveness. While both phones likely utilize LPDDR4X RAM, the 888’s superior memory controller will further enhance the Xperia 5 III’s performance.

Battery Life

Both phones share a 100-hour endurance rating, suggesting similar real-world battery life despite the Xperia 5 III’s more power-hungry chipset. This is likely achieved through software optimizations and a relatively efficient display. However, charging speeds differ: the Axon 20 5G Extreme supports 30W QC4 charging, reaching 60% in 30 minutes, while the Xperia 5 III supports wired PD charging, achieving 50% in the same timeframe. While the difference isn’t massive, the Axon 20’s QC4 support may offer faster charging with compatible adapters.

Buying Guide

Buy the ZTE Axon 20 5G Extreme if you need a forward-thinking device with 5G and are intrigued by the under-display camera, all while staying within a tighter budget. Buy the Sony Xperia 5 III if you prioritize top-tier performance for gaming and content creation, demand a compact form factor, and value Sony’s dedicated camera features and software optimizations.
