  • Clean and intuitive Android software experience

  • Significantly slower 23W charging
  • Potentially lower raw processing power compared to Snapdragon

Display Comparison

The Pixel 6 Pro boasts a measured peak brightness of 846 nits, providing excellent visibility outdoors. While the Mix 4’s peak brightness isn’t specified, Xiaomi typically delivers competitive displays. Both feature high contrast ratios, with the Pixel 6 Pro claiming an 'infinite' (nominal) ratio. The Mix 4’s under-display camera is a unique feature, maximizing screen real estate, but potentially impacting front camera quality. The Pixel 6 Pro’s curved display edges contribute to a more immersive viewing experience, though some users may prefer the Mix 4’s potentially flatter panel.

Camera Comparison

The Pixel 6 Pro’s camera system is heavily reliant on Google’s computational photography, leveraging the Tensor chip’s AI capabilities. While specific sensor details aren’t provided, the Pixel 6 Pro excels in dynamic range and image clarity, particularly in challenging lighting conditions. The Mix 4’s camera specs are not provided, but Xiaomi flagships typically feature high-resolution sensors and advanced features. The Tensor chip’s image processing pipeline offers features like Magic Eraser and Motion Mode, unavailable on the Mix 4. The Pixel 6 Pro’s focus on software optimization gives it an edge in overall image quality.

Performance

Both phones utilize 5nm fabrication processes, but differ in their chipsets. The Xiaomi Mix 4 features the Qualcomm Snapdragon 888+ 5G, with a prime core clocked at 2.99 GHz (Cortex-X1). The Google Pixel 6 Pro is powered by Google’s in-house Tensor chip, featuring a similar Cortex-X1 configuration at 2.80 GHz. While clock speeds are comparable, the Tensor chip’s strength lies in its dedicated AI processing units, enhancing features like voice recognition and image processing. Both utilize an octa-core configuration with similar mid and low-power cores (A78 and A55). The Mix 4’s Snapdragon 888+ is known for its raw processing power, while the Tensor prioritizes machine learning tasks.

Battery Life

Both devices achieve an endurance rating of 84 hours, suggesting similar real-world battery life despite differing battery capacities (not specified for the Mix 4). However, the charging speeds are drastically different. The Xiaomi Mix 4 supports a staggering 120W wired charging, achieving a full charge in just 15 minutes. It also offers 50W wireless charging, reaching 100% in 28 minutes. The Pixel 6 Pro, in contrast, is limited to 23W wired charging, taking 30 minutes to reach 50%. The Mix 4’s charging speed is a significant advantage for users who frequently need to top up their battery quickly.

Buying Guide

Buy the Xiaomi Mix 4 if you need the absolute fastest charging available, a powerful processor for demanding tasks, and don't mind a less refined software experience. Buy the Google Pixel 6 Pro if you prefer a clean Android experience, exceptional camera capabilities powered by Google’s Tensor chip, and a focus on intelligent features like Magic Eraser.

Frequently Asked Questions

❓ Does the Xiaomi Mix 4's 120W charging degrade the battery health faster?
While extremely fast charging can theoretically contribute to battery degradation over the long term, Xiaomi incorporates intelligent charging algorithms and safety mechanisms to mitigate this effect. The phone monitors battery temperature and adjusts charging speed accordingly, minimizing potential damage. However, long-term testing is needed to fully assess the impact.
❓ How does the Google Tensor chip's AI processing benefit everyday use on the Pixel 6 Pro?
The Tensor chip enhances several aspects of the Pixel 6 Pro experience. It powers features like Magic Eraser in Google Photos, allowing you to remove unwanted objects from images. It also improves voice recognition for Google Assistant, enabling faster and more accurate responses. Furthermore, it enhances the camera's ability to process images, resulting in better low-light performance and dynamic range.
❓ Is the under-display camera on the Xiaomi Mix 4 noticeable during normal use?
While Xiaomi has minimized the visibility of the under-display camera, it can be slightly noticeable in certain lighting conditions and when viewing content with a lot of white or bright colors. However, most users report that it doesn't significantly detract from the overall viewing experience.
