Xiaomi 12 vs Xiaomi 15 Ultra

The Verdict

These flagships represent different generations of Xiaomi's premium lineup, with the 15 Ultra delivering substantially more power and versatility for serious mobile photographers. The 12 pairs a capable Snapdragon 8 Gen 1 with a solid 6.28-inch 120Hz AMOLED display and reliable 50MP main camera with OIS, offering smooth performance for everyday tasks and gaming. However, the 15 Ultra dominates nearly every specification: its Snapdragon 8 Elite processor is markedly faster, the 6.73-inch LTPO AMOLED screen reaches 3200 nits peak brightness versus 1100 nits, and resolution jumps to 3200x1440. Camera capabilities diverge significantly, with the 15 Ultra's larger 1-inch 50MP sensor paired with optical image stabilization, plus a dedicated 200MP 5x periscope telephoto and 50MP ultrawide that shoots 128 degrees. The 15 Ultra also includes IP68 dust and water resistance, faster 90W charging, a larger 5810mAh battery, and USB 3.2 connectivity. The 12 remains competent at $749 for budget-conscious buyers, but at $999, the 15 Ultra justifies its $250 premium through superior imaging, durability, and flagship silicon. Unless budget is tight, the 15 Ultra is the clear winner for long-term performance and photography quality.
