Motorola Razr Plus (2024) vs Xiaomi 15 Ultra
The Verdict
Both flagship phones deliver premium experiences at the $999 price point, but they excel in different areas. Motorola's Razr Plus 2024 showcases the foldable form factor with a 6.9-inch inner AMOLED display at 165Hz and a practical 4.0-inch cover screen, both impressively bright at 3000 nits. Its 50MP main camera with f/1.7 and OIS pairs well with the 2x telephoto zoom. The Snapdragon 8s Gen 3 handles everything smoothly, though the 4000mAh battery feels modest for a foldable device. Xiaomi's 15 Ultra takes a more traditional flagship approach with superior raw specifications: 5810mAh battery supporting 90W wired and 50W wireless charging, a 6.73-inch 3200x1440 LTPO AMOLED display at 3200 nits, and more capable camera hardware including a 200MP 5x periscope telephoto and 1-inch main sensor. The Snapdragon 8 Elite processor outperforms the 8s variant, and 16GB RAM standard provides future-proofing. Xiaomi weighs 229g versus Motorola's 188.8g, and its IP68 rating beats IP48. If you prioritize camera versatility, display resolution, and battery longevity, the Xiaomi 15 Ultra offers measurably better specifications. However, Motorola's foldable innovation appeals if you value the unique dual-screen experience and lighter form factor despite compromises in battery capacity and charging speeds.
