ASUS Zenfone 10 vs Xiaomi 15 Ultra
The Verdict
These phones target vastly different market segments. The Zenfone 10 excels as a compact flagship with its 5.92-inch display, 144Hz refresh rate, and Gimbal OIS for stabilized video in a lightweight 172g body. Its Snapdragon 8 Gen 2, 8GB/16GB RAM, and 4300mAh battery deliver solid performance for everyday users. The 15 Ultra commands a $300 premium for tangible upgrades: 6.73-inch 3200x1440 LTPO display with extraordinary 3200-nit peak brightness, Snapdragon 8 Elite chip, 16GB standard RAM, and a 5810mAh battery supporting 90W charging and 50W wireless. The camera systems differ strategically. Zenfone 10 prioritizes the main 50MP Sony IMX766 with Gimbal OIS for video excellence, while 15 Ultra adds a 200MP 5x periscope telephoto and 50MP ultrawide on its 1-inch main sensor, offering superior zoom range and versatility. 15 Ultra's 229g weight and larger form factor require consideration for those valuing portability. At $699, the Zenfone 10 delivers exceptional value for compact phone enthusiasts and content creators needing stabilization. The 15 Ultra justifies its premium through flagship specifications, superior display technology, and comprehensive camera system. Choose Zenfone 10 for portability and gimbal video; select 15 Ultra for display quality, zoom capability, and overall performance ceiling.
