Display Comparison
Both phones feature displays with an 'Infinite' contrast ratio, suggesting excellent black levels typical of OLED panels. However, detailed specifications like peak brightness and color accuracy are missing. Given Xiaomi's history with vibrant displays, it's likely the Mi 9T Pro leans towards a more saturated look, while OnePlus typically aims for greater color accuracy. The lack of high refresh rate panels (90Hz or 120Hz) is a commonality, placing both phones behind newer offerings. Bezels are comparable, offering an immersive viewing experience for the time.
Camera Comparison
Both phones are listed as having 'Photo / Video' capabilities, lacking specific details. Given the era, both likely feature multi-camera setups. Without sensor size or aperture information, a direct comparison is difficult. However, Xiaomi often emphasizes camera features, suggesting the Mi 9T Pro might offer more software-driven enhancements. The absence of detail regarding OIS (Optical Image Stabilization) is a significant omission; its presence would be a major advantage for video recording and low-light photography. We can assume both phones include standard modes like portrait and night mode, but image quality will depend heavily on the underlying hardware and software processing.
Performance
The core difference lies in the chipset: the OnePlus 7T boasts the Snapdragon 855+, while the Mi 9T Pro uses the standard Snapdragon 855. While both are 7nm chips with an identical CPU core configuration (Octa-core: 1x2.84/2.96 GHz Kryo 485, 3x2.42 GHz Kryo 485, 4x1.78 GHz Kryo 485), the 855+ features a slightly higher clock speed and an improved GPU. This translates to a modest performance advantage for the 7T in sustained gaming and demanding tasks. However, the difference is unlikely to be noticeable in everyday use. Both phones benefit from 8GB of RAM, ensuring smooth multitasking.
Battery Life
The Xiaomi Mi 9T Pro clearly wins in battery endurance with a rating of 103 hours, compared to the OnePlus 7T's 90 hours. This 14-hour difference is substantial and translates to a noticeable advantage for the Mi 9T Pro in real-world usage. Furthermore, the Mi 9T Pro supports 27W wired charging with Quick Charge 4, while the OnePlus 7T offers 30W Warp Charge. While 30W is nominally faster, Quick Charge 4's efficiency and compatibility with a wider range of chargers could provide a more consistent charging experience. The Mi 9T Pro's larger battery capacity combined with efficient charging gives it a clear edge.
Buying Guide
Buy the OnePlus 7T if you prioritize a clean, optimized software experience with OxygenOS and are willing to trade a bit of battery life for it. It's ideal for users who frequently switch between apps and value a smooth, responsive interface. Buy the Xiaomi Mi 9T Pro if you prioritize maximum battery life and faster charging, and don't mind MIUI's more feature-rich, but sometimes cluttered, software. This phone is perfect for power users and those who heavily rely on their phone throughout the day.
