iQOO Z9s Pro vs Y400 Pro 5G

The vivo iQOO Z9s Pro wins on battery and charging: 5500mAh with 80W wired charging (50% in 21 min) vs. the Y400 Pro’s 5500mAh with 90W (50% in 19 min), but the Z9s Pro’s 120Hz AMOLED display with 4500-nit peak brightness and OIS on the 50MP main camera deliver superior real-world usability. Buy the Z9s Pro if you need faster charging, better display brightness, and optical image stabilization for sharper photos in low light. Buy the Y400 Pro if you prioritize the latest Android 15 and slightly lighter weight (182g vs. 185g), accepting slower charging and no OIS. In UAE at AED 800 vs. AED 950, the Z9s Pro is better because it offers 512GB storage and a brighter display for AED 150 less. In India at ₹31999 vs. ₹25999, the Y400 Pro wins on value because it costs ₹6000 less despite matching battery and offering Android 15.
