Sony Xperia XZ1

  • Superior battery life (82h endurance)
  • Higher display contrast ratio for better image quality
  • Identical processing power to the XZ Premium

  • Potentially less bright display in direct sunlight compared to XZ Premium
  • Camera specifications are unknown, making a direct comparison difficult

Sony Xperia XZ Premium

  • Good sunlight readability (2.877 contrast ratio)
  • Identical processing power to the XZ1
  • Potentially more premium build quality (based on market positioning)

  • Shorter battery life (72h endurance)
  • Lower display contrast ratio for less vibrant images
  • Higher price point at launch (likely)

Display Comparison

The Xperia XZ1 boasts a contrast ratio of 1406 (nominal) and 3.765 in sunlight, indicating strong visibility even in bright conditions. The XZ Premium, while still offering good sunlight readability at 2.877, falls behind with a lower nominal contrast ratio of 1238:1. This difference suggests the XZ1 will deliver deeper blacks and a more vibrant image in typical indoor lighting. Both displays utilize similar IPS LCD technology, but the XZ1’s superior contrast contributes to a more visually appealing experience.

Camera Comparison

Both devices share the same 'Photo / Video' camera capabilities as listed, lacking specific details for a detailed comparison. Without sensor size, aperture, or image processing details, it’s difficult to definitively state which camera is superior. However, Sony’s brand reputation suggests both phones deliver competent image quality, focusing on natural color reproduction. The absence of information regarding features like OIS or low-light performance makes a conclusive assessment impossible.

Performance

Both the Xperia XZ1 and XZ Premium are powered by the Qualcomm MSM8998 Snapdragon 835 (10 nm) chipset, featuring an octa-core CPU configuration (4x2.45 GHz Kryo & 4x1.9 GHz Kryo). This means performance will be virtually identical across most tasks, including gaming and multitasking. The 10nm process node ensures efficient power consumption, but the real-world impact is mitigated by the differing battery capacities and optimizations. Neither device features advanced cooling solutions, so sustained peak performance will be limited by thermal throttling.

Battery Life

The Xperia XZ1’s endurance rating of 82 hours is a significant advantage over the XZ Premium’s 72 hours. This translates to a tangible difference in real-world usage, allowing the XZ1 to comfortably last a full day with moderate to heavy use. Both phones support 18W wired charging with Quick Charge 3.0 (QC3), offering similar charging speeds. Despite the XZ Premium potentially having a slightly larger battery (unspecified in the data), the XZ1’s superior optimization results in longer battery life.

Buying Guide

Buy the Sony Xperia XZ1 if you need a phone that will reliably last a full day, or even longer, on a single charge. It’s ideal for users who frequently travel or have limited access to power outlets. Buy the Sony Xperia XZ Premium if you prioritize maximum screen brightness and contrast in direct sunlight, and are willing to accept a shorter battery life. This phone caters to those who consume a lot of media outdoors.

Frequently Asked Questions

❓ Does the Snapdragon 835 in either phone show signs of throttling during extended gaming sessions?
While the Snapdragon 835 is a capable chipset, neither the XZ1 nor the XZ Premium feature advanced cooling solutions. Expect some degree of thermal throttling during prolonged, graphically intensive gaming. Performance will likely dip slightly after 30-45 minutes of continuous play, but both phones should still provide a playable experience.
❓ How does the display on the XZ Premium perform in direct sunlight compared to other flagship phones from 2017?
With a sunlight contrast ratio of 2.877, the XZ Premium’s display offers good, but not exceptional, visibility in direct sunlight. Competitors like the Samsung Galaxy S8 and S9 offered significantly brighter displays with higher peak brightness levels, making them easier to view outdoors. The XZ Premium is adequate, but not class-leading, in this regard.
❓ Is the difference in battery endurance between the XZ1 and XZ Premium noticeable in everyday use?
Yes, the 10-hour difference in endurance rating is quite noticeable. Users of the XZ1 can expect to comfortably get through a full day of moderate to heavy use without needing to recharge, while XZ Premium users may find themselves reaching for a charger by late afternoon, especially with demanding tasks.
