iPhone 17 vs Xiaomi 15 Ultra

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 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

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 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

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 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

Solid full-day battery life with efficiency gains from the A19 chip, though it does not break any records in the iPhone lineup.

• Comfortably lasts through a full day of moderate to heavy use, ending the day with 15-20% remaining
• MagSafe wireless charging and wired charging are adequate but fall behind Pro model speeds

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

Full iOS 26 with Apple Intelligence — no AI feature compromises versus the Pro models.

• All Apple Intelligence features including writing tools, notification summaries, and Siri enhancements work identically to Pro models
• Clean software experience with years of guaranteed updates makes this a great long-term investment

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
