Display Comparison

While both phones utilize OLED panels, specific display details are missing. However, given Xiaomi’s history, the Mi 9 Pro likely features a higher peak brightness and potentially a higher refresh rate than the Pixel 4 XL. The Pixel 4 XL’s display is known for its color accuracy, but the Mi 9 Pro’s panel likely offers a more vibrant and modern viewing experience. Bezels are expected to be comparable, typical of flagship devices from this era.

Camera Comparison

The Pixel 4 XL is renowned for its computational photography prowess, leveraging Google’s software to produce exceptional images, particularly in low-light conditions. While the Mi 9 Pro’s camera specs are not detailed, it’s reasonable to assume it features a multi-camera system. However, the Pixel 4 XL’s strength lies in its image processing, consistently delivering excellent dynamic range and accurate colors. The Pixel 4 XL’s video capabilities are also strong, offering excellent stabilization and detail. Without specific sensor details for the Mi 9 Pro, it’s difficult to make a direct comparison, but the Pixel 4 XL likely holds an edge in overall image quality.

Performance

Both devices are powered by the Qualcomm Snapdragon 855 series, but the Mi 9 Pro boasts the Snapdragon 855+ while the Pixel 4 XL uses the standard 855. The 855+ features a slightly higher clock speed (2.96 GHz vs 2.84 GHz) and improved GPU performance. While the difference isn’t massive, it translates to marginally faster app loading times and smoother gaming. Both phones share 6GB of RAM, but the Mi 9 Pro’s superior thermal management, likely due to a larger chassis, could result in less throttling during sustained workloads. The CPU core configuration is nearly identical, with 1x Kryo 485 prime core, 3x performance cores, and 4x efficiency cores on both.

Battery Life

Both phones achieve an endurance rating of 73 hours, suggesting similar real-world battery life. However, the Mi 9 Pro significantly outperforms the Pixel 4 XL in charging speed. The Mi 9 Pro supports 40W wired charging with QC4, allowing for a full charge in under an hour. It also features 30W wireless charging and 10W reverse wireless charging. The Pixel 4 XL, limited to 18W wired charging with PD2.0 and slower wireless charging, takes considerably longer to replenish its battery. This difference in charging speed is a major advantage for the Mi 9 Pro, especially for users who frequently need to top up their devices.

Buying Guide

Buy the Xiaomi Mi 9 Pro if you prioritize fast charging speeds, a potentially longer usable lifespan due to newer technology, and a more aggressive price point. You'll benefit from the convenience of 30W wireless charging and the ability to quickly top up your battery. Buy the Google Pixel 4 XL if you are a photography enthusiast who values Google’s image processing algorithms and a clean, bloatware-free Android experience, and are willing to accept slower charging and potentially shorter battery life.
