iPhone 17 Pro Max vs Xiaomi 15 Ultra

iPhone 17 Pro Max

The 6.9-inch Super Retina XDR display pushes peak brightness to 3,000 nits with ProMotion 120Hz, making it the most sunlight-readable phone on the market.

• 3,000-nit peak brightness is a major jump that makes the phone perfectly readable even in direct sunlight — the best outdoor display on any phone
• Display stays brighter for longer under sustained sunlight thanks to the vapor chamber thermal management
• Color accuracy and HDR performance remain class-leading with excellent DCI-P3 coverage

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 Max

The triple 48MP camera system delivers refined computational photography with improved low-light performance, though hardware changes are evolutionary rather than revolutionary.

• All three rear cameras now use 48MP sensors, providing consistently high detail across ultrawide, main, and telephoto shots
• Low-light photography takes a meaningful step forward with cleaner noise handling and better night sky detail
• Video recording remains the gold standard — no Android phone comes close to the ProRes and LOG workflow quality
• Compared to the 16 Pro Max, the camera hardware upgrades feel incremental — the differences are often only visible in side-by-side comparisons

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 Max

The A19 Pro chip combined with vapor chamber cooling delivers best-in-class sustained performance with 40% better thermal management than the previous generation.

• A19 Pro benchmarks show a meaningful single-core leap and the best sustained performance of any smartphone tested — no throttling even under prolonged loads
• Gaming performance with vapor chamber cooling is noticeably smoother, with more consistent frame rates in demanding titles
• On-device AI processing through Apple Intelligence is fast and responsive, with live transcription and summarization working seamlessly

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 Max

The iPhone 17 Pro Max delivers the best battery life of any iPhone ever, lasting 17+ hours in web browsing tests. 40W wired charging is a welcome improvement but still trails Android competitors.

• Lasted 17 hours and 54 minutes in the web browsing test — the longest battery life ever recorded in an iPhone, beating the 16 Pro Max by over an hour
• Moderate users can easily achieve 1.5 to 2 days between charges with mixed usage
• 40W fast charging reaches 50% in under 30 minutes — a significant jump from the 27W of previous models, but still slower than 80W+ Android competitors
• No charger included in the box means you need to buy a compatible brick separately to get the maximum charging speed

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 Max

iOS 26 brings Visual Intelligence, enhanced Siri with on-device AI, and deep Apple Intelligence integration, though some promised features arrived late after launch.

• Apple Intelligence features including writing tools, notification summaries, and image generation are well integrated and genuinely useful
• Visual Intelligence through the camera is impressive for real-time translation, object identification, and contextual search
• Some iOS 26 features feel unfinished at launch, with Apple promising additional capabilities in subsequent updates

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
