400 Pro vs iPhone 17 Pro Max
How these two compare on everything we measure — where the AIs rank them, what reviewers and buyers say, and how they price. The differences are the point — they decide which one is yours.
Side by side
Every signal we hold, on one shared scale. The leading side is lit — and where the AI panel and the reviewers pull apart, the row says so.?
Built from what 5 AI models (ChatGPT · Gemini · Google-ai-mode · Claude · Perplexity) recommend for real buyer questions, layered with reviewer test summaries, Google buyer ratings, street prices and press. The short answer and verdict are derived from where those signals diverge — not written by hand for either product.

Critics & buyers
The human jury in one chapter — what the video reviewers score and say, the reviews behind it, and how Google buyers rate them.
What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Outstanding battery life, with multiple reviewers calling it a two-day battery under normal use and noting record-low drain in standardised tests
- Camera system delivers excellent image quality, strong dynamic range, and capable low-light performance from the main sensor, with ProRAW and Log modes offering genuine professional utility
- A19 Pro chip delivers substantial CPU and GPU performance gains, aided by a vapor chamber that keeps thermals in check during everyday workloads
Reviewers push back
- Aluminum anodization is susceptible to scratching and spalling; the camera island in particular picks up surface damage even under modest use
- Thermal stress tests reveal the phone throttles CPU performance more aggressively than its predecessor, undermining Apple's cooling claims under sustained load
- iOS 26 carries software bugs: Wi-Fi re-enables itself after manual disable, background location sharing is unreliable, and dictation quality lags behind competing platforms
The iPhone 17 Pro Max earns broad praise for its camera system, exceptional battery life, and sustained performance, but draws real concern over aluminum durability, thermal throttling under stress, and iOS software rough edges.
Vapor chamber cooling: CNET and Dave2D report noticeably cooler sustained operation compared to prior models, while GSMArena's stress tests show more CPU throttling than last year's device — reviewers cannot agree on whether cooling is improved or worse
