ASUS Zenfone 12 Ultra vs Nothing Phone (3)

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

Nothing Phone (3)

A sharp 6.7-inch LTPO AMOLED with 120Hz and up to 2,000 nits peak brightness delivers a smooth, vibrant viewing experience.

• The LTPO OLED panel is bright, responsive, and color-accurate — a significant improvement over the Phone (2) display
• Peak brightness of 2,000 nits is good but falls behind Samsung and Apple flagships hitting 3,000 nits

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

Nothing Phone (3)

Snapdragon 8 Elite puts the Nothing Phone (3) in the same performance tier as Samsung Galaxy S25 and OnePlus 13.

• Snapdragon 8 Elite provides genuinely flagship-level performance — gaming, multitasking, and app launches are all top-tier
• Nothing OS 3 is lightweight enough to let the hardware shine, with smooth animations and minimal background resource consumption
• Thermals are well managed with the aluminum frame acting as a heat sink, keeping sustained performance respectable

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

Nothing Phone (3)

The triple camera system co-developed with Samsung is a major upgrade, though processing still trails the best in challenging conditions.

• The 50MP main camera produces detailed, well-exposed shots in good light that compete with phones costing $200 more
• Telephoto lens addition brings welcome versatility with clean 3x optical zoom results
• Night mode and low-light processing lag behind Google and Samsung — images lack the computational magic of Pixel phones
• Video stabilization and dynamic range are adequate but noticeably behind iPhone and Galaxy flagships in side-by-side tests
