What Reviewers Agree On

Grade-5 titanium frame makes it ~20g lighter than the 14 Pro Max — most-praised in-hand feel of any iPhone yet (221g)
A17 Pro 3nm chip with hardware ray tracing — fastest mobile silicon at launch, future-proofs for Apple Intelligence on iOS 18
5x Tetraprism periscope telephoto (120mm) is Pro Max exclusive — first iPhone to break past 3x optical, with computational zoom to 25x
USB-C 3.0 finally arrives on iPhone (10Gbps on Pro/Max only — standard 15 caps at USB 2.0 speeds)
Customizable Action Button replaces the mute switch — opens camera, shortcut, focus mode, voice memo, magnifier and more

Detailed Comparison

Cameras

iPhone 15 Pro Max

48MP main + 12MP ultrawide + 12MP 5x Tetraprism periscope telephoto (Pro Max exclusive) + 12MP TrueDepth selfie. The 5x periscope is the headline upgrade — first iPhone past 3x optical, with computational zoom up to 25x.

Cameras: 48MP main (f/1.78, sensor-shift OIS), 12MP ultrawide (f/2.2, 13mm), 12MP 5x Tetraprism periscope telephoto (120mm, f/2.8), 12MP TrueDepth selfie.
5x Tetraprism is Pro Max EXCLUSIVE — the smaller iPhone 15 Pro is capped at 3x telephoto, the first time Apple meaningfully gated a camera feature by size.
Computational zoom extends usable range to 10x and 25x — beyond that, optical clarity degrades, but the 5x base is a meaningful step up from 3x.
vs Samsung S23 Ultra's 10x periscope — Samsung still wins at maximum reach; iPhone wins on natural color, video stabilization and ecosystem.

6.7" Super Retina XDR ProMotion 120Hz at 2000-nit peak — the best phone display Apple has shipped

USB-C 3.0 + Action Button + lighter titanium are the upgrades reviewers say justify the $1,199 price

6+ years of iOS updates — confirmed runway through iOS 23+ in 2030s

Deal Breakers

Launch overheating issues — A17 Pro ran hot in gaming and 4K shoots; iOS 17.0.3 mitigated but didn't fully eliminate it
Battery life regressed slightly vs the 14 Pro Max in several real-world tests — owners coming from older iPhones may notice the drop
$1,199 starting (256GB now base vs 128GB previously) is the most-expensive baseline iPhone Apple has shipped
Pro Max-exclusive 5x periscope means the Pro is stuck at 3x — those wanting compact + long zoom are out of luck
Notable owner complaints: titanium frame discolors with hand oils, the matte finish picks up fingerprints visibly

OnePlus Open

What Reviewers Agree On

Best book-style foldable hardware of 2023 — thinner (5.8mm unfolded), lighter (245g) than Z Fold 5 (253g)
Cover screen aspect ratio (20:9) finally works like a real phone, unlike Z Fold 5's narrow 23.1:9
Inner display crease is meaningfully less visible than the Z Fold 5's — most-praised hinge design of the era
Hasselblad triple cameras (48MP main + 64MP 3x telephoto + 48MP ultrawide) outshoot the Z Fold 5 noticeably
67W wired + 50W wireless charging — dramatically faster than Z Fold 5's 25W wired / no wireless
OxygenOS Open Canvas multitasking — best foldable software outside Samsung One UI

Deal Breakers

IPX4 water resistance only — no dust rating; Z Fold 5 has IPX8 (full water immersion)
Only 4 OS + 5 years of security — short vs Pixel Fold's 7 years
No S Pen support — Samsung Z Fold 5's biggest software advantage
Alert Slider is missing from this OnePlus model (only foldable without it)
$1,699 launch was 'less expensive than Z Fold 5 by $100' but still steep for a first-gen foldable

Hasselblad-tuned triple-camera system clearly outshoots the Z Fold 5: 48MP main (LYT-T808 1-inch-class sensor) + 64MP 3x telephoto periscope + 48MP ultrawide. Best foldable cameras of 2023.

Cameras: 48MP main (LYT-T808 1-inch-class, f/1.7, OIS), 64MP 3x telephoto periscope (f/2.6, 70mm), 48MP ultrawide (f/2.2), 32MP cover selfie + 20MP inner.
Hasselblad color tuning delivers more natural shots than Z Fold 5; periscope telephoto reaches 3x optical / 6x quality-preserving.
Best foldable cameras of 2023 — clearly outshoots Z Fold 5 in main + telephoto; on par with Pixel Fold for ultrawide.
Still trails slab flagships (S23 Ultra, iPhone 15 Pro Max) on absolute camera quality — physical sensor limits remain a foldable constraint.
