Xiaomi 12 Pro vs Xiaomi 15 Ultra
The Verdict
Both phones share the same $999 price point and 6.73-inch display, but the Xiaomi 15 Ultra represents a significant generational leap. Its Snapdragon 8 Elite processor substantially outperforms the 12 Pro's Gen 1 chip, while the 1-inch main sensor and 200MP 5x periscope telephoto deliver dramatically superior imaging capabilities compared to the dual 50MP setup. Battery capacity grows from 4600mAh to 5810mAh, though charging drops from 120W to 90W. Display brightness nearly doubles to 3200 nits, and IP68 rating provides proper dust/water resistance absent on the 12 Pro. Storage maxes at 1TB versus 256GB. The 15 Ultra weighs 24g more, and HyperOS 2 replaces MIUI 13. For flagship photography and current-generation performance, the 15 Ultra clearly justifies its identical price through superior hardware across nearly every metric. Choose the 15 Ultra unless you specifically prefer lighter weight or faster charging.
