Apple iPhone X vs Xiaomi 14 Ultra
The Verdict
Comparing these phones reveals a generational leap between Apple's 2017 flagship and Xiaomi's 2024 powerhouse. The iPhone X established the notch and OLED standard with its 5.8-inch Super Retina display at 625 nits and 60Hz refresh rate, paired with the efficient A11 Bionic chip and dual 12MP cameras. Its 2716 mAh battery supports 18W wired and 7.5W wireless charging, while the stainless steel build delivers premium feel at $999. The Xiaomi 14 Ultra operates in a different league entirely. Its 6.73-inch LTPO AMOLED screen reaches 3000 nits with 120Hz refresh rate, delivering dramatically superior brightness and smoothness. The Snapdragon 8 Gen 3 and 16GB RAM crush the A11 Bionic, while the camera system is remarkable: a 50MP 1-inch main sensor with variable aperture, dual 50MP telephoto options, and 8K video versus the iPhone X's 4K at 60fps. Battery capacity nearly doubles to 5300 mAh with 90W wired and 80W wireless charging. IP68 and USB-C add modern conveniences. However, the Xiaomi costs $500 more and weighs 50g extra. For historical context, the iPhone X was exceptional for 2017, but seven years of mobile advancement make the Xiaomi 14 Ultra objectively superior in every technical category. Choose the iPhone X only for iOS ecosystem preference; the Xiaomi dominates on specifications and capability.
