iPhone 17 Air vs Xiaomi 15 Ultra

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 Ultra

A stunning 6.73-inch 2K LTPO AMOLED with 120Hz, 3,200 nits peak brightness, and Dolby Vision support.

• 3,200 nits peak brightness is the highest of any smartphone tested, with excellent outdoor visibility and HDR performance
• 2K resolution with 120Hz LTPO delivers incredibly sharp, smooth visuals for gaming and media consumption

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 Ultra

The crown jewel — a triple Leica camera system with a 1-inch main sensor, 200MP telephoto, and 50MP ultrawide that redefines smartphone photography.

• The 1-inch main sensor captures more light and detail than any competing smartphone camera — photos have a depth and quality that approaches dedicated cameras
• 200MP telephoto with 4.3x optical zoom produces incredibly detailed zoom shots that rival the Galaxy S25 Ultra's 5x periscope
• Leica color science produces warm, film-like tones with natural skin rendering that photographers love
• Video stabilization is the best on any Android phone, though color consistency and dynamic range in video still trail the iPhone

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 Ultra

Snapdragon 8 Elite with 16GB RAM delivers the fastest Android performance available with excellent thermal management.

• Snapdragon 8 Elite with 16GB RAM makes this one of the fastest phones tested — no app or game can slow it down
• Liquid cooling system keeps sustained performance high with minimal throttling during extended gaming sessions
• 16GB RAM ensures smooth multitasking with dozens of apps in memory and efficient AI processing

iPhone 17 Air

Battery life is the iPhone 17 Air's Achilles heel — the thin chassis leaves little room for a large cell, and it shows in endurance tests.

• Battery life is roughly 70% of the standard iPhone 17 and 56% of the Pro Max — heavy users will need a mid-day charge
• Light to moderate users can get through a full day, but with noticeably less margin than any other iPhone 17 model
• 30W charging is respectable for the battery size and provides quick top-ups throughout the day

Xiaomi 15 Ultra

A 5,500mAh battery with 90W wired and 50W wireless charging delivers both excellent endurance and class-leading charging speeds.

• 90W wired charging fills the 5,500mAh battery from 0 to 100% in about 35 minutes — among the fastest in any flagship
• Battery easily lasts a full day of heavy use including intensive camera work and gaming
• 50W wireless charging is fast enough to replace wired charging for most daily use scenarios

iPhone 17 Air

Full iOS 26 with Apple Intelligence, though some on-device AI tasks process slightly slower than on Pro models.

• All Apple Intelligence features are available including writing tools, notification summaries, and image generation
• Some AI tasks like video processing and complex image editing take noticeably longer than on Pro models

Xiaomi 15 Ultra

HyperOS 2 on Android 15 is feature-rich but divisive — powerful customization options are offset by ads and bloatware in some regions.

• HyperOS 2 is more polished than MIUI, with smooth animations, useful sidebar multitasking, and deep customization
• Pre-installed apps and occasional ads in system UI detract from the premium experience in some regional variants
• Four years of OS updates and five years of security updates — decent but short of Samsung and Google seven-year commitments
