Display Comparison

The Pixel 3a XL's display shines with a measured 451 nits of brightness, making it far more usable outdoors. Its 'infinite' contrast ratio suggests excellent black levels and vibrant colors. The Nexus 5X's 1542 contrast ratio is respectable, but the sunlight visibility at 3.092 is a significant disadvantage compared to the Pixel 3a XL.

Camera Comparison

The Pixel 3a XL's camera is a major upgrade. Google's computational photography prowess delivers stunning images, especially in low light. The Nexus 5X's camera is adequate for basic photography, but it struggles in challenging conditions and lacks the advanced features of the Pixel 3a XL.

Performance

The Pixel 3a XL's Snapdragon 670 chipset, built on a more efficient 10nm process, offers a noticeable performance boost over the Nexus 5X's Snapdragon 808. While the Nexus 5X's hexa-core CPU is decent, the Pixel 3a XL's octa-core processor handles multitasking and demanding apps with greater ease. The 360 Gold and Kryo cores provide a balanced approach to power and efficiency.

Battery Life

The Pixel 3a XL dominates in battery life, achieving an endurance rating of 98 hours compared to the Nexus 5X's 60 hours. This represents a substantial difference in real-world usage. The Pixel 3a XL also supports 18W wired charging and PD2.0, offering faster charging speeds.

Buying Guide

The LG Nexus 5X is best for users seeking a very affordable, compact Android phone for basic tasks and those who appreciate its smaller form factor. The Google Pixel 3a XL is ideal for users prioritizing battery life, camera quality, and a smooth Android experience, especially those on a budget.
