Samsung Galaxy S22 Ultra vs Xiaomi 15 Ultra
The Verdict
Samsung's Galaxy S22 Ultra remains a premium flagship, but Xiaomi's 15 Ultra delivers superior value with meaningful advantages across several fronts. The 15 Ultra features a larger 5810 mAh battery (vs 5000 mAh) with dramatically faster 90W charging and 50W wireless charging, compared to the S22 Ultra's 45W and 15W. Display brightness reaches 3200 nits on the Xiaomi versus 1750 nits on Samsung, making outdoor visibility noticeably better. Camera capabilities favor Xiaomi's 1-inch 50 MP main sensor and 200 MP periscope telephoto with genuine 5x optical zoom, while the S22 Ultra's 108 MP main sensor and dual telephoto setup feel less versatile. Performance-wise, the Snapdragon 8 Elite and 16 GB RAM standard on the 15 Ultra outpace the S22 Ultra's Snapdragon 8 Gen 1 with 8 GB. The Galaxy S22 Ultra retains advantages in One UI's refinement, proven software longevity, and S Pen integration that Xiaomi lacks. At $200 less, the 15 Ultra's newer processor, better charging speeds, superior display brightness, and larger battery make it the more compelling choice for most buyers, though Samsung loyalists may value One UI's polish and ecosystem integration.
