Display Comparison
Both devices boast 'Infinite' contrast ratios, indicating excellent OLED panel quality. However, the Mi Mix Alpha’s defining feature is its wrap-around display, extending onto the sides of the device. This is a visual spectacle, but introduces usability challenges with accidental touches and a lack of traditional buttons. The OnePlus 8 Pro features a more conventional 6.78-inch Fluid AMOLED display with a 120Hz refresh rate (not specified for the Mi Mix Alpha), offering a smoother scrolling experience. While the Mi Mix Alpha’s display is innovative, the OnePlus 8 Pro’s is demonstrably more practical for everyday use.
Camera Comparison
Both phones feature capable camera systems, but details on the Mi Mix Alpha’s camera are limited. The OnePlus 8 Pro’s camera system is well-documented, offering a versatile setup for both photo and video. The OnePlus 8 Pro’s strengths lie in its image processing, delivering consistently good results in various lighting conditions. Without detailed specifications for the Mi Mix Alpha’s camera, it’s difficult to make a direct comparison, but the OnePlus 8 Pro’s established reputation and feature set (like its ultrawide lens) give it an edge.
Performance
The OnePlus 8 Pro’s Snapdragon 865 5G chipset represents a significant leap over the Mi Mix Alpha’s Snapdragon 855+. The 865, built on a 7nm+ process, offers improved CPU and GPU performance, alongside integrated 5G connectivity. The CPU architecture differs; the OnePlus 8 Pro utilizes Cortex-A77 cores, while the Mi Mix Alpha uses Kryo 485 cores. While both are octa-core designs, the A77 cores generally exhibit higher single-core performance. The OnePlus 8 Pro’s access to faster LPDDR5 RAM (spec not provided for Mi Mix Alpha, but likely LPDDR4X) further enhances responsiveness. This translates to snappier app loading, smoother multitasking, and better gaming performance on the OnePlus 8 Pro.
Battery Life
The OnePlus 8 Pro boasts an endurance rating of 103 hours, indicating excellent battery life. It supports 30W wired charging (50% in 23 minutes) and 30W wireless charging (50% in 30 minutes), alongside 3W reverse wireless charging. The Mi Mix Alpha, with its 40W wired charging, offers faster wired charging speeds, but lacks wireless charging capabilities. The OnePlus 8 Pro’s superior endurance rating suggests it will comfortably last a full day of moderate to heavy use, while the Mi Mix Alpha’s battery life may be more dependent on usage patterns.
Buying Guide
Buy the Xiaomi Mi Mix Alpha if you prioritize a truly unique and futuristic design, and are willing to accept potential software quirks and limited real-world usability due to the wrap-around display. Buy the OnePlus 8 Pro if you value a polished software experience, consistently high performance thanks to the Snapdragon 865, a versatile camera system, and excellent battery life – a combination that caters to a wider range of users.
