iPhone 17 Air vs Xiaomi 15

iPhone 17 Air

The 6.6-inch OLED display with ProMotion 120Hz is excellent, though peak brightness does not match the Pro models.

• The 6.6-inch display is gorgeous with vivid colors, deep blacks, and smooth 120Hz scrolling
• Peak brightness of 2,000 nits is good but falls short of the Pro models 3,000-nit panels

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 Air

A single 48MP main camera delivers good photos but severely limits versatility compared to the dual and triple camera systems on other iPhone 17 models.

• The 48MP main camera produces excellent photos with great color accuracy and solid dynamic range in good lighting
• No ultrawide or telephoto means you are stuck with digital zoom and no wide-angle shots — a significant limitation for $899
• Night mode and low-light performance are decent but cannot match the Pro models computational multi-frame processing

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 Air

The A19 (non-Pro) chip handles daily tasks effortlessly but lacks the GPU horsepower and Neural Engine cores of the Pro variant.

• Day-to-day performance is indistinguishable from the Pro models — apps launch fast, multitasking is smooth
• Gaming performance falls behind the Pro models by about 15-20% in GPU-intensive titles
• Thermals are well managed given the thin chassis, though sustained workloads cause more noticeable warm spots

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
