Huawei Mate 20 X (5G)
- 40W SuperCharge for incredibly fast charging
- Larger display potentially better for media consumption
- Potentially deeper Huawei ecosystem integration
- Kirin 980 chipset is outperformed by Snapdragon 855
- Potentially more thermal throttling under sustained load
Xiaomi Mi Mix 3 5G
- Snapdragon 855 delivers superior performance
- Quick Charge 4 compatibility for wider charger support
- More compact design for easier handling
- Slower 18W charging compared to Mate 20 X (5G)
- May require proprietary charger for optimal charging speeds
Display Comparison
While both devices featured large displays, specific details like panel type and resolution are missing. However, the Mate 20 X’s larger size suggests a focus on media consumption. The Mi Mix 3, known for its nearly bezel-less design, likely prioritized maximizing screen real estate within a more compact form factor. The absence of high refresh rate technology on either device is typical for the 2019 flagship segment, but limits the smoothness of scrolling and animations compared to modern displays.
Camera Comparison
Without detailed camera specs, a direct comparison is difficult. However, both phones were positioned as flagship devices, suggesting capable camera systems. The image processing philosophies likely differed – Huawei historically favored vibrant, sometimes oversaturated images, while Xiaomi often aimed for a more natural look. The presence of 5G connectivity suggests both phones were capable of faster image uploads and cloud storage integration. The absence of information on sensor sizes makes it impossible to determine which phone had an advantage in low-light performance.
Performance
The core difference lies in the chipsets: Huawei’s Kirin 980 (7nm) versus Qualcomm’s Snapdragon 855 (7nm). The Snapdragon 855, with its Kryo 485 cores clocked up to 2.84 GHz, generally delivers superior CPU and GPU performance compared to the Kirin 980’s Cortex-A76 and A55 configuration. The Snapdragon 855’s architecture is optimized for sustained performance, potentially leading to less thermal throttling during extended gaming sessions. While both utilize 7nm fabrication, Qualcomm’s design typically exhibits better power efficiency. The Mi Mix 3 5G likely benefits from faster LPDDR4X RAM, contributing to quicker app loading and multitasking.
Battery Life
The Huawei Mate 20 X (5G) supports 40W wired charging, significantly faster than the Xiaomi Mi Mix 3 5G’s 18W charging with Quick Charge 4. This translates to substantially quicker 0-100% charging times for the Mate 20 X. However, the Mi Mix 3 5G’s Quick Charge 4 compatibility offers broader charger support and potentially better efficiency at lower power levels. The actual battery life will depend on usage patterns, but the faster charging of the Mate 20 X provides a convenience advantage.
Buying Guide
Buy the Huawei Mate 20 X (5G) if you prioritize a larger display and are deeply embedded in the Huawei ecosystem, potentially benefiting from software optimizations. Buy the Xiaomi Mi Mix 3 5G if you value peak performance, faster application loading times, and a more standardized fast-charging experience. The Mi Mix 3 5G is also a better choice for users who frequently game or use demanding applications.
