Display Comparison

Both the Xperia XZ and XZ1 feature displays with comparable sunlight contrast ratios around 3.795, indicating excellent outdoor visibility. However, the XZ1 edges out the XZ with a nominal contrast ratio of 1406 versus 1349. While not a dramatic difference, this suggests slightly deeper blacks and a more vibrant image. Neither phone boasts high refresh rate panels, focusing instead on color accuracy and brightness. The lack of detailed panel specifications (like OLED vs IPS) means we can only assume both utilize Sony’s Triluminos display technology for enhanced color reproduction.

Camera Comparison

Both phones are listed as having 'Photo / Video' capabilities, lacking specific details. Given Sony’s expertise in imaging, both likely deliver strong image quality. However, without sensor size or aperture information, a direct comparison is difficult. The Snapdragon 835 in the XZ1 benefits from an improved image signal processor (ISP), potentially leading to faster image processing, better low-light performance, and more accurate color reproduction. The XZ1’s newer processor could also enable more advanced computational photography features, though specifics are unavailable. We can assume both phones offer similar video recording capabilities, given Sony’s focus on video quality.

Performance

The core difference between these two devices lies in their chipsets. The Xperia XZ1’s Qualcomm MSM8998 Snapdragon 835, built on a 10nm process, represents a significant leap over the XZ’s Snapdragon 820 (14nm). The 835’s octa-core CPU (4x2.45 GHz Kryo & 4x1.9 GHz Kryo) provides substantially more processing power than the XZ’s quad-core configuration (2x2.15 GHz Kryo & 2x1.6 GHz Kryo). This translates to faster app loading times, smoother multitasking, and improved gaming performance. The 10nm process also contributes to better thermal efficiency, potentially reducing throttling during sustained workloads. The XZ1’s architecture is simply more modern and capable.

Battery Life

The Xperia XZ1 boasts an endurance rating of 82 hours, a 10-hour improvement over the XZ’s 72-hour rating. This difference, while not massive, is attributable to the more efficient Snapdragon 835 processor. Both phones support 18W wired charging with Quick Charge 3.0, offering similar charging speeds. The XZ1’s improved efficiency means it can deliver longer usage times on a single charge, making it the better choice for users who prioritize battery life. The 10nm process of the Snapdragon 835 is key to this improvement.

Buying Guide

Buy the Sony Xperia XZ1 if you prioritize performance for demanding tasks like gaming or video editing, and want the longest possible software support lifespan. Buy the Sony Xperia XZ if you are on a tighter budget and value a proven, reliable experience with a still-capable processor, and don't require the absolute latest processing power.

Frequently Asked Questions

❓ Will I notice a significant performance difference between the Snapdragon 820 and 835 in everyday use?
For basic tasks like browsing and social media, the difference will be minimal. However, when running demanding apps, playing graphically intensive games, or multitasking heavily, the Snapdragon 835 in the XZ1 will provide a noticeably smoother and more responsive experience. The 835’s improved architecture and efficiency are key here.
❓ How much longer can I expect the Xperia XZ1 to last on a single charge compared to the XZ?
The XZ1’s 82-hour endurance rating suggests approximately 10 hours of additional usage compared to the XZ’s 72 hours. This translates to a full extra day of moderate use for many users, thanks to the more efficient Snapdragon 835 processor and its 10nm manufacturing process.
❓ Is the camera on the XZ1 a substantial upgrade over the XZ?
Without detailed camera specifications, it's difficult to quantify the improvement. However, the Snapdragon 835’s improved ISP likely results in faster image processing, better low-light performance, and potentially more accurate colors. The XZ1 may also benefit from more advanced computational photography features.
