iPhone 17 Pro vs Xiaomi 15

iPhone 17 Pro

The 6.3-inch Super Retina XDR display matches the Pro Max with 3,000-nit peak brightness and ProMotion 120Hz in a more compact package.

• 3,000 nits peak brightness matches the Pro Max exactly — no display compromises in the smaller model
• ProMotion 120Hz with always-on display provides a smooth, responsive experience identical to the larger sibling

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 Pro

Identical triple 48MP camera system to the Pro Max — no feature or quality cuts in the smaller phone, which is a first for the Pro line.

• For the first time, the smaller Pro gets the exact same camera hardware as the Pro Max — no telephoto compromise
• Low-light photography improvements are consistent across both Pro models with the new computational pipeline
• ProRes and LOG video recording match the Pro Max, making this the most capable compact video phone

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 Pro

A19 Pro chip with vapor chamber cooling delivers identical benchmark scores and sustained performance as the Pro Max.

• Benchmark scores are virtually identical to the Pro Max — the smaller form factor imposes no performance penalty
• Sustained performance under load is excellent thanks to the vapor chamber, though the smaller chassis runs slightly warmer

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
