Apple iPhone XS Max vs Xiaomi 15 Ultra

The Verdict

These phones represent different eras of mobile technology. The iPhone XS Max launched in 2018 with a 6.5-inch Super Retina OLED display at 725 nits and the A12 Bionic processor, delivering solid performance for its time with a dual 12MP camera system and 4K@60fps video. Battery capacity stands at 3174 mAh with 18W wired and 7.5W wireless charging. The Xiaomi 15 Ultra is a 2024 flagship offering substantially more advanced specifications: a larger 6.73-inch LTPO AMOLED display with 3200 nits peak brightness and 1-120Hz refresh rate, the Snapdragon 8 Elite processor, and a comprehensive quad-camera setup featuring a 50MP main sensor with a 1-inch sensor, 200MP periscope telephoto, and 8K video recording. It includes 16GB RAM, a 5810 mAh battery with 90W wired and 50W wireless charging, plus 5G connectivity and Wi-Fi 7. The XS Max feels underpowered in 2024 with its 4GB RAM and 60Hz display. Storage options favor the Xiaomi with up to 1TB versus 512GB maximum. At $100 less, the Xiaomi 15 Ultra dramatically outperforms the XS Max in nearly every measurable category. The iPhone only advantage is iOS ecosystem familiarity and brand longevity, insufficient to overcome the technological gap.
