Display Comparison
Both phones feature AMOLED displays with a 1190:1 contrast ratio, promising vibrant colors and deep blacks. The Poco X4 GT measures 600 nits of brightness, which is respectable. The vivo S15 Pro is expected to have a slightly higher peak brightness and potentially a more color-accurate display, though specific measurements are needed for a definitive comparison. The S15 Pro likely has a higher refresh rate (90Hz or 120Hz) compared to the Poco X4 GT's 60Hz, resulting in smoother scrolling and animations.
Camera Comparison
The vivo S15 Pro is expected to have a significant advantage in the camera department. While both offer 'Photo / Video' capabilities, vivo is known for its strong selfie cameras and image processing. The S15 Pro likely features a higher resolution main sensor and potentially more advanced features like OIS (Optical Image Stabilization). The Poco X4 GT's camera is likely adequate but won't match the S15 Pro's capabilities.
Performance
Both devices are powered by the Mediatek Dimensity 8100 chipset, ensuring smooth performance for everyday tasks and demanding games. While the chipset is identical, software optimization and thermal management could differ, impacting real-world performance. The Poco X4 GT might have slightly better cooling due to its design, potentially sustaining peak performance for longer durations during intensive gaming.
Battery Life
The Poco X4 GT shines in this category. Its endurance rating of 112h is exceptional, indicating outstanding battery life. It also boasts 67W wired charging, completing a full charge in 46 minutes. The vivo S15 Pro offers 80W wired charging, which is faster, but its battery capacity is likely smaller, resulting in a slightly shorter battery life and potentially a longer charging time (18 minutes to 70%).
Buying Guide
The vivo S15 Pro is ideal for users prioritizing camera quality, a sleek design, and potentially a more premium feel. The Xiaomi Poco X4 GT is a great pick for gamers and power users who need long battery life, fast charging, and a competitive price.
