iPhone 17 vs Xiaomi 15 Ultra

Xiaomi 15 Ultra wins on battery life with 16:13h active use versus iPhone 17’s 1000 cycles and 41:00h endurance, though the latter’s endurance metric is ambiguous—real-world usage favors Xiaomi’s 5410mAh (global) vs iPhone’s estimated 4000mAh equivalent. Buy the iPhone 17 if you need seamless iOS 26.4 updates, MagSafe/Qi2 wireless charging at 15W, and 3000-nit peak brightness for outdoor HDR visibility. Buy the Xiaomi 15 Ultra if you demand 90W wired and 80W wireless charging to refill from 0–50% in under 15 minutes, and a 522 ppi 3200x1440 display for sharper detail. In UAE at AED 3499 vs AED 3999, iPhone 17 is better because it offers superior display peak brightness and longer software support; in India at ₹89900 vs ₹104999, Xiaomi 15 Ultra wins on value because its 90W charging and higher-resolution screen justify the ₹15099 premium.
