Motorola Edge (2021)

  • More affordable price point
  • 144Hz display refresh rate
  • Smooth performance for everyday tasks

  • Less powerful Snapdragon 778G chipset
  • Display brightness likely lower than Xperia 5 III
  • Camera details are limited

Sony Xperia 5 III

  • Flagship Snapdragon 888 performance

  • Faster charging capabilities

  • Significantly higher price
  • Potential for thermal throttling
  • Compact size may not suit all users

Display Comparison

The Sony Xperia 5 III boasts a brighter display, measured at 590 nits, compared to the Motorola Edge (2021)'s unspecified brightness. This difference is noticeable in direct sunlight. While both offer excellent contrast ratios (infinite nominal for the Xperia 5 III), the Xperia’s smaller 6.1-inch screen contributes to a higher pixel density, resulting in a sharper image. The Edge (2021) counters with a 144Hz refresh rate, potentially offering smoother scrolling and gaming, though the Xperia 5 III’s 120Hz is still very responsive. The lack of LTPO on either device means refresh rate scaling isn't as efficient as on newer flagships.

Camera Comparison

Both phones offer photo and video capabilities, but details are limited. The Xperia 5 III, being a Sony product, likely benefits from their renowned image processing expertise. While sensor sizes aren't specified, the Xperia 5 III’s focus on professional video features suggests a more sophisticated camera system. The Motorola Edge (2021) likely offers a more versatile camera setup for general use, but the Xperia 5 III is geared towards users who demand high-quality video recording and advanced photographic controls. The absence of details on the Edge's camera specs makes a direct comparison difficult, but Sony's brand reputation in imaging is a significant advantage.

Performance

The core difference lies in the chipsets. The Sony Xperia 5 III’s Snapdragon 888 5G (5nm) significantly outperforms the Motorola Edge (2021)’s Snapdragon 778G 5G (6nm). The 888 features a Cortex-X1 prime core clocked at 2.84 GHz, versus the Edge’s Cortex-A78 at 2.4 GHz. This translates to faster app loading, smoother multitasking, and superior gaming performance. While the 6nm process of the 778G offers better efficiency, the 5nm 888’s raw power is undeniable. Both devices utilize an octa-core configuration with similar mid and low-tier cores, but the Xperia 5 III’s superior architecture provides a clear advantage. Thermal management will be a key factor for the 888, potentially leading to throttling under sustained load.

Battery Life

Both devices share an endurance rating of 100 hours, suggesting comparable battery life despite differing charging speeds. The Sony Xperia 5 III offers faster charging at 50% in 30 minutes with PD support, while the Motorola Edge (2021) takes longer with its 30W wired charging. The actual battery capacity isn't specified for either device, but the Snapdragon 888’s higher power consumption in the Xperia 5 III is likely offset by software optimizations and potentially a slightly larger battery. The faster charging on the Xperia 5 III is a convenience factor for users who need a quick power boost.

Buying Guide

Buy the Motorola Edge (2021) if you need a capable 5G smartphone with a smooth 144Hz display and solid performance for everyday tasks and moderate gaming, all without breaking the bank. Buy the Sony Xperia 5 III if you prioritize top-tier performance for demanding applications like video editing, gaming, and photography, and value a compact form factor with a bright, high-quality display.

Frequently Asked Questions

❓ Will the Snapdragon 888 in the Xperia 5 III overheat during extended gaming sessions?
The Snapdragon 888 is known to generate significant heat under sustained load. Sony likely implemented thermal management solutions, but some throttling is possible during prolonged gaming. The Xperia 5 III’s compact size may limit the effectiveness of these solutions compared to larger phones.
❓ Is the 144Hz display on the Motorola Edge (2021) a noticeable improvement over a standard 60Hz or 120Hz display?
The 144Hz refresh rate on the Motorola Edge (2021) provides a smoother visual experience, particularly in fast-paced games and scrolling. However, the difference between 120Hz and 144Hz is less noticeable than the jump from 60Hz to 120Hz. Whether it's worth the trade-off depends on your sensitivity to motion blur and your gaming habits.
❓ Does the Sony Xperia 5 III support external displays for professional video editing?
Yes, the Sony Xperia 5 III is designed with content creators in mind and supports external display output via USB-C, allowing for connection to monitors for a larger workspace during video editing and other professional tasks.
