OnePlus Nord 4 vs Xiaomi 15
The Verdict
Both phones deliver flagship performance at different price points, but the Xiaomi 15 justifies its $100 premium with superior specifications across nearly every category. The Nord 4 excels with its massive 5500 mAh battery and excellent value proposition at $499, featuring a bright 2150-nit display, solid 50 MP camera with OIS, and the capable Snapdragon 7+ Gen 3 processor that handles daily tasks smoothly. However, the Xiaomi 15 counters with the flagship Snapdragon 8 Elite chip, a brighter 3200-nit display, superior camera setup including a 50 MP telephoto lens with 2.6x optical zoom and 8K video recording, plus wireless charging at 50W. The Xiaomi's lighter 191g build and IP68 rating also edge out the Nord 4's IP65 protection. The Nord 4's primary advantage remains battery longevity and charging speed at 100W, though the Xiaomi's 90W wired plus 50W wireless offsets this considerably. For budget-conscious buyers prioritizing battery life and raw value, the Nord 4 excels, but those wanting comprehensive flagship features including optical zoom, wireless charging, and superior video capabilities should opt for the Xiaomi 15.
