iPhone 17 Pro vs Xiaomi 15 Ultra

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 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 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 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 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 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 Pro

Battery life is strong for a 6.3-inch phone but cannot match the Pro Max. Heavy users should expect to charge by late evening.

• Comfortably lasts a full day for most users, with around 12 hours of screen-on time in mixed use
• Falls about 3-4 hours short of the Pro Max in endurance tests — the trade-off for the smaller size
• 40W fast charging matches the Pro Max and is a meaningful improvement over the 16 Pro

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 Pro

Identical iOS 26 experience with full Apple Intelligence, Visual Intelligence, and enhanced Siri capabilities.

• Full parity with Pro Max on all iOS 26 and Apple Intelligence features — no software downgrades
• Still fresh after months of use, with regular iOS updates continuing to add AI capabilities post-launch

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
