Display Comparison
Both the OnePlus 7T Pro and Xiaomi Mi 9T Pro boast displays with an 'Infinite' (nominal) contrast ratio, indicating excellent black levels typical of AMOLED panels. However, the OnePlus 7T Pro’s 90Hz refresh rate is a key differentiator, providing a noticeably smoother scrolling and gaming experience compared to the Mi 9T Pro’s standard 60Hz panel. While neither manufacturer explicitly details peak brightness, the OnePlus 7T Pro’s display is generally reported to be slightly brighter in real-world usage, improving visibility in direct sunlight. Both displays utilize similar PWM dimming rates, meaning sensitivity to flicker will likely be comparable for users prone to eye strain.
Camera Comparison
Both phones offer capable camera systems, but detailed specifications beyond 'Photo / Video' are lacking. Given the market positioning, it’s reasonable to assume both rely on similar Sony IMX sensors. The OnePlus 7T Pro likely benefits from slightly more refined image processing algorithms, a hallmark of OnePlus’s software optimization. The Mi 9T Pro, however, may offer more versatile shooting modes due to Xiaomi’s tendency to include a wider range of features. Without detailed sensor size or aperture information, a definitive camera winner is difficult to declare, but the OnePlus 7T Pro likely holds a slight edge in overall image quality consistency.
Performance
The core performance difference lies in the chipsets: the OnePlus 7T Pro features the Qualcomm Snapdragon 855+ (7nm), while the Xiaomi Mi 9T Pro uses the standard Snapdragon 855 (7nm). The 855+ boasts a slightly higher clock speed – 2.96 GHz for the prime core versus 2.84 GHz on the 855 – and a more efficient architecture. This translates to a small but measurable performance boost in benchmarks and sustained workloads. Both phones share the same CPU core configuration (Octa-core: 1x2.96/2.84 GHz Kryo 485 & 3x2.42 GHz Kryo 485 & 4x1.78 GHz Kryo 485). The impact of this difference is most noticeable during prolonged gaming sessions, where the 855+ in the 7T Pro is less prone to thermal throttling. Both devices likely utilize LPDDR4X RAM, as LPDDR5 was not widespread at this price point during their release.
Battery Life
The Xiaomi Mi 9T Pro claims a slightly longer endurance rating of 103 hours compared to the OnePlus 7T Pro’s 100 hours. This suggests marginally better battery life in typical usage scenarios. However, the OnePlus 7T Pro compensates with significantly faster 30W wired charging, compared to the Mi 9T Pro’s 27W wired charging with Quick Charge 4 (QC4) support. While the difference in charging speed isn’t dramatic, it translates to a quicker top-up time. The Mi 9T Pro’s QC4 support offers broader compatibility with various chargers, while the OnePlus 7T Pro’s Warp Charge 30T is optimized for OnePlus’s proprietary chargers.
Buying Guide
Buy the OnePlus 7T Pro if you prioritize consistent performance during demanding tasks like gaming or video editing, and appreciate the smoother experience offered by the 90Hz display. Buy the Xiaomi Mi 9T Pro if you value maximizing battery life and quick top-ups, and are less concerned with having the absolute fastest processor in this price bracket. Both phones are excellent choices, but cater to slightly different user needs.
