Samsung Galaxy Z Flip 5 vs Xiaomi 15 Ultra
The Verdict
Samsung's Galaxy Z Flip 5 delivers a unique foldable form factor at $999.99, pairing a compact 3.4-inch cover display with a spacious 6.7-inch inner AMOLED screen. Its 187g weight and slim 6.9mm profile make it highly portable, though the 3700 mAh battery struggles with all-day endurance. Camera performance is respectable with a 12MP main sensor and OIS, supporting 4K@60fps video. The Snapdragon 8 Gen 2 for Galaxy handles performance admirably, and 25W charging is adequate for the modest battery size. Xiaomi's 15 Ultra demands attention with flagship specs at nearly identical pricing. Its 1-inch 50MP main sensor with f/1.63 aperture outclasses the Z Flip 5's camera system significantly, complemented by a 200MP telephoto with 5x optical zoom and 8K@30fps video capability. The 5810 mAh battery nearly triples the Z Flip's capacity, supported by 90W wired and impressive 50W wireless charging. Display brightness peaks at 3200 nits versus 1600, and the 3200x1440 resolution crushes the Z Flip's 2640x1080. However, the 15 Ultra weighs 229g and measures 9.17mm thick, sacrificing portability. The newer Snapdragon 8 Elite with 16GB RAM provides more raw power, though real-world differences are minimal. Choose the Z Flip 5 for its innovative foldable design and pocketability. Select the 15 Ultra for superior cameras, battery life, display quality, and raw specifications. The Xiaomi offers substantially better value on specs alone.
