Sony Xperia XZ1

  • Lower price point, offering excellent value.
  • Slightly higher nominal display contrast ratio.
  • Proven reliability and software support.

  • Older Snapdragon 835 chipset limits performance.
  • Shorter battery life compared to the XZ2 Compact.

Sony Xperia XZ2 Compact

  • Significantly faster Snapdragon 845 processor.
  • Improved battery endurance.
  • Enhanced image processing capabilities.

  • Generally higher price than the XZ1.
  • Slightly lower nominal display contrast ratio.

Display Comparison

Both the XZ1 and XZ2 Compact feature displays with a peak sunlight contrast ratio of 3.765, ensuring excellent visibility outdoors. However, the XZ1 boasts a slightly higher nominal contrast ratio of 1406 compared to the XZ2 Compact’s 1315:1. This difference, while measurable, is unlikely to be perceptible to most users. Neither Sony specified panel technology (IPS or OLED) or refresh rates, suggesting standard 60Hz IPS LCDs were used, common for the era. Bezels are comparable, focusing on maximizing screen real estate within the compact form factor.

Camera Comparison

Both devices are listed as having Photo/Video capabilities, but detailed sensor information is absent. Given Sony’s expertise, both likely feature capable cameras. The XZ2 Compact benefits from the improved image signal processor (ISP) within the Snapdragon 845, enabling faster image processing, better low-light performance, and potentially enhanced video stabilization. Without specific sensor size or aperture data, it’s difficult to definitively declare a camera winner, but the 845’s ISP gives the XZ2 Compact an edge. The lack of detail regarding secondary cameras suggests they were likely standard offerings for the time, and not a key differentiating factor.

Performance

The core difference lies in the chipset: the XZ1 utilizes the Qualcomm MSM8998 Snapdragon 835 (10nm), while the XZ2 Compact steps up to the SDM845 Snapdragon 845 (10nm). The 845 offers a significant CPU upgrade, with its octa-core configuration (4x2.7 GHz Kryo 385 Gold & 4x1.7 GHz Kryo 385 Silver) exceeding the XZ1’s (4x2.45 GHz Kryo & 4x1.9 GHz Kryo). This translates to approximately 25-30% faster CPU performance in benchmarks. The 845’s Adreno 630 GPU also provides a substantial graphics boost, benefiting gamers and users of graphically intensive applications. Both devices share the same 4GB of RAM, but the 845’s improved memory controller contributes to smoother multitasking.

Battery Life

The XZ2 Compact edges out the XZ1 in battery endurance, achieving an 88-hour rating versus the XZ1’s 82 hours. This 6-hour improvement, while not massive, is noticeable in real-world usage. Both support 18W wired charging with Quick Charge 3.0, meaning charging speeds are comparable. The Snapdragon 845’s improved power efficiency contributes to the XZ2 Compact’s longer battery life, despite not having a significantly larger battery capacity.

Buying Guide

Buy the Sony Xperia XZ1 if you prioritize value and already own an older flagship. It remains a capable device, and its lower price point makes it an attractive option for budget-conscious buyers. Buy the Sony Xperia XZ2 Compact if you demand the best possible performance in a compact package, appreciate faster processing speeds for demanding apps, and want a slightly longer-lasting battery.

Frequently Asked Questions

❓ Does the Snapdragon 845 in the XZ2 Compact offer a noticeable gaming improvement over the XZ1?
Yes, the Snapdragon 845’s Adreno 630 GPU provides a substantial graphics boost. Expect significantly higher frame rates and smoother gameplay in demanding titles compared to the XZ1’s Adreno 540. The 845 also handles thermal throttling more effectively, maintaining performance for longer gaming sessions.
❓ Is the battery life difference between the XZ1 and XZ2 Compact significant enough to warrant an upgrade?
The 6-hour endurance rating difference is noticeable, especially for moderate to heavy users. While not a dramatic leap, the XZ2 Compact’s improved power efficiency translates to less frequent charging throughout the day. This is a key benefit for those who rely heavily on their smartphones.
❓ Given the similar display specs, is there a visible difference in image quality between the two phones?
While both have comparable sunlight contrast, the slightly higher nominal contrast ratio of the XZ1 might offer marginally deeper blacks. However, this difference is subtle and unlikely to be noticeable in everyday use. Both displays deliver a good viewing experience.
