Sony Xperia XZ1

  • Excellent battery endurance (82h)
  • More affordable price point (due to age)
  • Still a capable performer for everyday tasks

  • Older Snapdragon 835 chipset
  • Inferior display contrast ratio
  • Lacks wireless charging

Sony Xperia XZ3

  • Faster Snapdragon 845 chipset
  • Superior display with 'Infinite' contrast
  • Wireless charging (Qi) and PD2.0 support

  • Slightly higher price
  • Battery life improvement is incremental, not massive

Display Comparison

The Xperia XZ3 boasts a significant display upgrade. While both phones share a similar aspect ratio, the XZ3’s ‘Infinite’ contrast ratio (compared to the XZ1’s 1406:1 nominal) indicates a superior panel, likely utilizing OLED technology, offering deeper blacks and more vibrant colors. The XZ3 also achieves a higher contrast ratio in sunlight (4.502 vs 3.765), improving outdoor visibility. While both displays are excellent, the XZ3’s offers a more premium and immersive visual experience. The XZ1's display, while still good, is likely an LCD panel and will not offer the same level of color accuracy or contrast.

Camera Comparison

Both the XZ1 and XZ3 feature capable photo and video cameras, but detailed specifications beyond 'Photo / Video' are missing. Given Sony’s expertise in imaging sensors, it’s reasonable to assume both phones utilize high-quality sensors. However, the XZ3 likely benefits from improved image processing algorithms and potentially a larger sensor size, resulting in better low-light performance and dynamic range. Without specific sensor details, it’s difficult to definitively declare a winner, but the XZ3’s newer processor allows for more sophisticated image processing.

Performance

The core performance difference lies in the chipsets. The XZ3’s Snapdragon 845 (10nm) represents a generational leap over the XZ1’s Snapdragon 835 (10nm). The XZ3’s CPU features faster Kryo 385 Gold cores (2.7 GHz vs 2.45 GHz) and Silver cores (1.7 GHz vs 1.9 GHz), resulting in quicker app launches, smoother multitasking, and improved gaming performance. While both chips are built on a 10nm process, the 845’s architectural improvements translate to a tangible performance advantage. The XZ3’s GPU also benefits from the upgrade, offering better graphics rendering capabilities.

Battery Life

The Xperia XZ3 edges out the XZ1 in battery endurance, achieving a rating of 90 hours compared to the XZ1’s 82 hours. This improvement, despite both phones featuring similar battery capacities (not specified in the data), is likely due to the more efficient Snapdragon 845 chipset. The XZ3 also introduces wireless charging (Qi standard) and supports Power Delivery 2.0 for faster wired charging, adding convenience and flexibility. While the XZ1 supports Quick Charge 3.0, the XZ3’s wireless charging and PD2.0 support provide a more modern charging experience.

Buying Guide

Buy the Sony Xperia XZ1 if you prioritize maximizing battery life and are seeking a flagship experience at a significantly lower price point. It remains a capable device for everyday tasks and photography. Buy the Sony Xperia XZ3 if you demand faster performance for demanding applications, appreciate a more modern design with wireless charging, and value a superior display experience with better contrast and viewing angles.

Frequently Asked Questions

❓ Does the Snapdragon 845 in the XZ3 offer a noticeable performance improvement over the 835 in the XZ1 for gaming?
Yes, the Snapdragon 845 in the XZ3 provides a tangible performance boost for gaming. The faster CPU and GPU cores, combined with architectural improvements, result in higher frame rates, smoother gameplay, and reduced thermal throttling, especially in demanding titles. While the XZ1 can handle most games, the XZ3 offers a more consistent and enjoyable gaming experience.
❓ Is the wireless charging on the XZ3 significantly faster than wired charging on the XZ1?
While wireless charging is convenient, it's generally slower than wired charging. The XZ3 supports Power Delivery 2.0 for faster wired charging, and it's likely that a full charge via wired connection will be quicker than wireless. However, the XZ3’s wireless charging offers a convenient top-up option that the XZ1 lacks.
❓ Given the age of both devices, are software updates still being provided?
Software update support for both the XZ1 and XZ3 is likely limited at this point. Sony typically provides a few years of major Android updates, and both devices are beyond that timeframe. Security patches may still be available, but users shouldn't expect significant new features or Android version upgrades.
