Samsung Galaxy Z Flip 4 vs Xiaomi 15

The Verdict

Samsung's Z Flip 4 remains a compelling foldable despite premium pricing, while Xiaomi's 15 delivers substantially better value with flagship specs at $400 less. The Z Flip 4's key appeal is its unique form factor: the 6.7-inch foldable display and compact 1.9-inch cover screen create genuine portability advantages, though the 3700 mAh battery feels tight for modern usage. Performance relies on Snapdragon 8+ Gen 1 with 8GB RAM, adequate but not cutting-edge. Camera system offers solid 12MP versatility with 4K@60fps video. Xiaomi 15 obliterates these specs: Snapdragon 8 Elite processor, 12GB RAM standard, 5400 mAh battery with 90W wired and 50W wireless charging versus Samsung's 25W/15W, and superior display brightness (3200 nits vs 1200). Camera setup is significantly stronger with 50MP main sensor (Light Fusion 900), 50MP telephoto with 2.6x zoom, and 8K video capability. The 6.36-inch conventional display doesn't match foldable innovation, but offers better practicality. Xiaomi edges ahead in raw performance, battery longevity, charging speed, and camera versatility. Samsung justifies its premium only if foldable design and cover screen novelty resonate with you. For most users prioritizing everyday performance and value, Xiaomi 15 offers dramatically better returns on investment.
