ASUS Zenfone 12 Ultra vs iPhone 17 Pro Max

ASUS Zenfone 12 Ultra

The 6.78-inch Samsung E6 AMOLED panel delivers 2,500 nits peak brightness with LTPO adaptive 1-120Hz (144Hz for gaming). Vivid colors and excellent outdoor readability are let down by FHD+ resolution at a price where competitors offer QHD+, and poor minimum brightness.

• 2,500 nits peak brightness with LTPO 1-120Hz and 144Hz gaming mode — vivid and responsive
• Same display panel as the Zenfone 11 Ultra — no improvement whatsoever year-over-year
• Only FHD+ resolution at EUR 1,099 — competitors offer QHD+ at this price tier

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

ASUS Zenfone 12 Ultra

Snapdragon 8 Elite delivers class-leading performance — described as "the fastest phone I used in 2025" by Android Central. The clean, near-stock Android 15 experience with no bloatware makes it one of the most fluid Android phones available. On-device Meta Llama 3 AI processing is private but slow.

• "The fastest phone I used in 2025" — Snapdragon 8 Elite with the best-tuned software on Android
• Clean near-stock Android 15 with zero bloatware — extremely fluid and well-optimized
• On-device Meta Llama 3 AI is privacy-friendly but slow — often faster to just do the task manually
• Aggressive thermal throttling under sustained loads — GPU benchmark scores lower than expected

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

ASUS Zenfone 12 Ultra

The standout is the 6-axis Hybrid Gimbal Stabilizer 4.0 which delivers uniquely impressive video stabilization — a 66% improvement over the predecessor. The 50MP main camera is solid in good light, but HDR processing produces visible ghosting artifacts, dynamic range suffers with crushed shadows and clipped highlights, and the overall camera system doesn't compete at this price tier.

• 6-axis Hybrid Gimbal Stabilizer is uniquely excellent for video — best-in-class stabilization
• HDR processing leaves visible ghosting artifacts in photos — a shocking flaw for a 2025 flagship
• Dynamic range issues: shadows frequently crushed, highlights clipped, colors washed out and cold
• "Better than midrange but not flagship level" — not competitive with Galaxy S25 Ultra or Pixel 9 Pro

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
