ASUS Zenfone 12 Ultra vs iPhone 17

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

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

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

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

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

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
