OnePlus 8

  • Superior battery endurance (108h)
  • Faster charging speed (22 min to 50%)
  • Better value for money

  • Older Snapdragon 865 chipset
  • Potentially lower peak camera performance

Sony Xperia 1 III

  • Newer Snapdragon 888 chipset
  • Wireless and reverse wireless charging
  • Potentially better image processing

  • Significantly lower battery endurance (82h)
  • Slower charging speed (30 min to 50%)
  • Lower peak display brightness

Display Comparison

The OnePlus 8 features a display capable of reaching 803 nits of peak brightness, providing good visibility outdoors. However, the Sony Xperia 1 III lags behind at 620 nits, potentially struggling in direct sunlight. Both displays share an 'Infinite' (nominal) contrast ratio, suggesting deep blacks, but the Xperia 1 III’s lower brightness impacts overall image vibrancy. While neither specification details refresh rate, the Xperia 1 III’s target audience would likely benefit from a higher refresh rate for smoother video playback, a feature the OnePlus 8 may or may not have.

Camera Comparison

Both phones offer photo and video capabilities, but the context data lacks specifics to make a definitive judgment. The Xperia 1 III’s Snapdragon 888 includes an upgraded Image Signal Processor (ISP), potentially leading to better image processing and low-light performance. However, without sensor size or aperture information, it’s difficult to assess the raw image quality. The Xperia 1 III’s focus on professional video recording suggests a more robust suite of video features, but the OnePlus 8’s camera system is likely capable of producing excellent results for casual users. The absence of detail regarding OIS on either device makes it impossible to compare stabilization performance.

Performance

The Sony Xperia 1 III’s Snapdragon 888 (5nm) represents a generational leap over the OnePlus 8’s Snapdragon 865 (7nm+). The 5nm process inherently offers improved power efficiency and thermal characteristics. The Xperia 1 III’s CPU configuration, featuring a Cortex-X1 prime core, promises faster single-core performance compared to the OnePlus 8’s Cortex-A77. However, the real-world performance difference may be less pronounced for typical tasks, and the OnePlus 8’s optimized software could mitigate the chipset gap. Both devices utilize Octa-core CPUs, but the architectural improvements in the Cortex-A78 cores of the Xperia 1 III contribute to a more modern and efficient processing experience.

Battery Life

The OnePlus 8’s endurance rating of 108 hours significantly surpasses the Sony Xperia 1 III’s 82 hours. This suggests the OnePlus 8 can comfortably last a full day of moderate to heavy use, while the Xperia 1 III may require more frequent charging. Despite both supporting 30W wired charging, the OnePlus 8 achieves 50% charge in 22 minutes, while the Xperia 1 III takes 30 minutes. The Xperia 1 III adds wireless and reverse wireless charging, offering convenience, but these features come at the cost of overall battery efficiency and slower charging speeds.

Buying Guide

Buy the OnePlus 8 if you need a reliable daily driver with excellent battery life and a smooth, responsive experience. It’s ideal for users who prioritize value and don’t require the absolute latest features. Buy the Sony Xperia 1 III if you are a content creator or enthusiast who values a more specialized feature set, and are willing to trade battery life for the potential benefits of the Snapdragon 888’s image signal processor and multimedia capabilities.

Frequently Asked Questions

❓ Does the Snapdragon 888 in the Xperia 1 III offer a noticeable gaming performance boost over the Snapdragon 865 in the OnePlus 8?
While the Snapdragon 888 is more powerful, the OnePlus 8’s Snapdragon 865 is still a capable performer. The Xperia 1 III will likely exhibit higher frame rates in demanding titles and potentially better sustained performance due to improved thermal management, but the difference may not be dramatic for casual gamers. The OnePlus 8’s software optimization could also help close the gap.
❓ Given the lower battery endurance of the Xperia 1 III, is it practical for all-day use with moderate to heavy usage?
The Xperia 1 III’s 82-hour endurance rating suggests it may struggle to last a full day with moderate to heavy use. Users who frequently use power-intensive apps, such as gaming or video streaming, will likely need to charge the device before the end of the day. The OnePlus 8, with its 108-hour rating, offers significantly more peace of mind in this regard.
❓ Does the Sony Xperia 1 III's wireless charging capabilities significantly impact battery health over time?
Wireless charging generally generates more heat than wired charging, which can contribute to battery degradation over the long term. While the Xperia 1 III offers the convenience of wireless charging, frequent use may slightly accelerate battery wear compared to primarily using the 30W wired charging option.
