Display Comparison
The iPhone 15 Plus features a display capable of reaching 1642 nits peak brightness, ensuring excellent visibility even in direct sunlight. While the Xiaomi 14 Pro’s display specifications aren’t provided, Xiaomi flagships typically prioritize high brightness and color accuracy. The iPhone’s adoption of Qi2 wireless charging suggests a focus on future-proofing display-related wireless standards. The lack of refresh rate information for the Xiaomi 14 Pro is a notable omission, but it’s likely to feature an adaptive refresh rate LTPO panel to balance smoothness and power efficiency.
Camera Comparison
Both devices are expected to deliver excellent camera performance, but specific details are limited. The iPhone 15 Plus is described as having a 'Photo / Video' camera system, implying a balanced approach. The Xiaomi 14 Pro, given Xiaomi’s recent history, likely features a larger main sensor and advanced computational photography algorithms. Without sensor size or aperture information for either device, a direct comparison is difficult. However, Xiaomi often emphasizes high megapixel counts, while Apple prioritizes image processing and color science.
Performance
At the heart of the iPhone 15 Plus lies the Apple A16 Bionic (4nm), a hexa-core chip with a unique architecture – two high-performance Everest cores clocked at 3.46 GHz and four efficiency-focused Sawtooth cores at 2.02 GHz. The Xiaomi 14 Pro counters with the Qualcomm Snapdragon 8 Gen 3 (4nm), an octa-core processor utilizing a 1x3.3 GHz Cortex-X4 prime core, 3x3.2 GHz Cortex-A720 performance cores, 2x3.0 GHz Cortex-A720 cores, and 2x2.3 GHz Cortex-A520 efficiency cores. The Snapdragon’s more numerous cores suggest potential advantages in multi-threaded tasks, while Apple’s optimized architecture often excels in single-core performance and power efficiency. The 4nm fabrication process in both chips contributes to improved thermal management, but real-world throttling will depend on each manufacturer’s cooling solutions.
Battery Life
The iPhone 15 Plus shines in battery endurance, achieving an impressive 16:33 hours of active use and an endurance rating of 111 hours. The Xiaomi 14 Pro, while lacking specific endurance figures, compensates with its incredibly fast charging capabilities. It supports 120W wired charging (PD3.0, QC4), reaching 100% in just 18 minutes – a significant advantage over the iPhone’s 30-minute 50% charge. Wireless charging is also faster on the Xiaomi, at 50W (100% in 40 minutes) compared to the iPhone’s 15W (MagSafe/Qi2, requiring iOS 17.2). The Xiaomi also offers 10W reverse wireless charging, while the iPhone provides a slower 4.5W reverse wired option.
Buying Guide
Buy the Apple iPhone 15 Plus if you need exceptional all-day battery life, a mature and polished software experience, and tight integration with other Apple devices. Buy the Xiaomi 14 Pro if you prioritize the fastest possible charging speeds, a more customizable Android experience, and cutting-edge hardware like the Snapdragon 8 Gen 3.
