Display Comparison

The Xperia 5 II boasts a measured peak brightness of 600 nits, a considerable improvement over the XZ1’s nominal 1406 contrast ratio (and 3.765 in sunlight). While the XZ1’s contrast ratio is respectable, the 5 II’s higher brightness translates to better visibility outdoors. The 5 II also claims an 'Infinite' contrast ratio, likely due to its OLED panel, offering deeper blacks and more vibrant colors compared to the XZ1’s LCD. The 5 II’s aspect ratio (21:9) also caters to content consumption, while the XZ1’s more standard ratio may appeal to those preferring a more conventional viewing experience.

Camera Comparison

Both devices feature capable photo and video capabilities, but the Xperia 5 II likely benefits from advancements in image processing and potentially a newer sensor. While specific sensor details are missing, the 5 II’s inclusion of the Snapdragon 865’s image signal processor (ISP) allows for improved noise reduction, dynamic range, and overall image quality. The XZ1’s camera was solid for its time, but the 5 II’s newer hardware and software provide a clear advantage, particularly in low-light conditions. The absence of detailed camera specs prevents a deeper analysis, but the 5 II’s newer platform is a strong indicator of superior performance.

Performance

The jump from the Snapdragon 835 in the XZ1 to the Snapdragon 865 in the Xperia 5 II is substantial. The 865, built on a 7nm+ process, offers significantly improved CPU and GPU performance. The 5 II’s CPU configuration – 1x2.84 GHz Cortex-A77, 3x2.42 GHz Cortex-A77, and 4x1.80 GHz Cortex-A55 – provides a noticeable advantage over the XZ1’s Octa-core (4x2.45 GHz Kryo & 4x1.9 GHz Kryo). The 5 II also benefits from faster RAM, though the specific LPDDR version isn’t specified, and supports 5G connectivity, a feature absent in the XZ1. This translates to smoother multitasking, faster app loading times, and a more responsive user experience.

Battery Life

The Xperia 5 II’s endurance rating of 102 hours represents a significant improvement over the XZ1’s 82 hours. This is likely due to a combination of the more efficient Snapdragon 865 chipset and potentially a slightly larger battery capacity (not specified in the data). The 5 II also supports 21W wired charging with PD3.0, capable of reaching 50% charge in just 30 minutes, a substantial upgrade over the XZ1’s 18W QC3 charging. This faster charging speed addresses a common complaint with older flagships, allowing for quicker top-ups throughout the day.

Buying Guide

Buy the Sony Xperia XZ1 if you prioritize a truly compact form factor and are on a tight budget, willing to accept older technology and potentially reduced software support. Buy the Sony Xperia 5 II if you demand modern performance for gaming and content creation, require 5G connectivity, and value significantly improved battery life and faster charging speeds. The 5 II is the better all-around device for power users.

Frequently Asked Questions

❓ Does the Snapdragon 865 in the Xperia 5 II get noticeably warmer than the Snapdragon 835 in the XZ1 during extended gaming sessions?
While the Snapdragon 865 is more powerful, it also generates more heat. However, Sony implemented thermal management solutions in the 5 II, and the 7nm+ process is more efficient. Users generally report manageable temperatures during gaming, though sustained high performance will inevitably lead to some warming. The XZ1, with its less powerful chip, will remain cooler, but at the cost of performance.
❓ Is the 21W charging on the Xperia 5 II a significant improvement over the XZ1's 18W charging in real-world use?
Yes, the 21W charging with PD3.0 on the 5 II is a substantial improvement. The ability to reach 50% charge in 30 minutes is a game-changer for users who frequently need to top up their battery quickly. The XZ1’s 18W charging, while adequate for its time, feels slow by comparison.
❓ Considering the Xperia 5 II's price point, is it still a competitive option in today's smartphone market?
At its original price of $695, the Xperia 5 II was positioned as a premium mid-range device. Now, with price drops, it represents excellent value for users seeking a compact flagship with modern features. While newer phones offer incremental improvements, the 5 II’s combination of performance, battery life, and unique features makes it a compelling option.
