iPhone 17 vs Xiaomi 15

iPhone 17

ProMotion 120Hz finally arrives on the standard iPhone, making the 6.1-inch OLED display significantly smoother than previous base models.

• ProMotion 120Hz is the single biggest upgrade — scrolling, animations, and general interaction feel dramatically smoother
• Peak brightness reaches 2,000 nits which is excellent for outdoor use though lower than the Pro 3,000-nit panels
• No always-on display despite ProMotion hardware — a frustrating omission to differentiate from the Pro line

Xiaomi 15

The 6.36-inch 1.5K LTPO OLED is sharp, vibrant, and incredibly bright at 3,200 nits peak (tested up to 3,593 nits HDR). Ultra-narrow 1.38mm bezels and high-frequency PWM dimming above 3,000Hz round out an excellent display package, though OLED smear at lower brightness is a noted concern.

• Peak brightness tested at 3,593 nits in HDR — among the brightest compact phone displays available
• Ultra-narrow 1.38mm bezels with excellent color accuracy in Original Color PRO profile
• OLED smear visible at lower brightness levels (0-70% range) — a recurring user complaint

iPhone 17

The 48MP main + 12MP ultrawide dual camera delivers impressive results with improved computational photography, though the lack of telephoto remains the biggest gap versus Pro.

• The 48MP main camera produces sharp, well-exposed photos with excellent color science that is nearly indistinguishable from Pro in good light
• The new 24MP TrueDepth front camera is a standout — selfie quality takes a major leap with better detail and more natural skin tones
• No telephoto means digital zoom only beyond 2x, which produces noticeably softer results than the Pro optical zoom

Xiaomi 15

The triple 50MP Leica system shines with its main sensor and improved 2.6x telephoto, earning a DxOMark score of 146. Leica color profiles produce natural, pleasing images with excellent dynamic range. The ultrawide camera is the clear weakness, with noticeably more noise in low light and no autofocus.

• 50MP main Leica Summilux camera delivers excellent photo quality with natural colors and strong dynamic range
• 2.6x optical telephoto is a meaningful upgrade over the Xiaomi 14 — sharp and versatile
• Ultrawide camera is the weakest link — subpar quality, no autofocus, noticeably more noise in low light
• DxOMark camera score of 146 — good but not class-leading among 2025 flagships

iPhone 17

The A19 chip handles daily tasks, gaming, and Apple Intelligence features with ease, providing a consistently smooth experience.

• A19 chip delivers more than enough power for everyday use — apps, multitasking, and Apple Intelligence all run smoothly
• Gaming performance is strong, with only a slight gap behind the A19 Pro in GPU-heavy titles

Xiaomi 15

The Snapdragon 8 Elite with 12GB RAM delivers flagship-tier performance that's smooth and snappy for everyday use, gaming, and multitasking. However, the compact body struggles to dissipate heat under sustained loads, causing notable thermal throttling during extended gaming sessions.

• Snapdragon 8 Elite scores ~2,990 single-core and ~9,114 multi-core on Geekbench 6 — genuinely fast
• Thermal throttling is a real issue — fails to complete 3DMark GPU stress tests and gets uncomfortably hot
• CPU throttles to 72-77% of peak under sustained load — compact chassis limits cooling capacity
