Best book-style foldable of 2023 — thinner, lighter, better cameras than Z Fold 5

iPhone 17 Pro Max

What Reviewers Agree On

The 4,823 mAh battery and A19 Pro efficiency deliver the longest battery life ever on an iPhone — Apple's 39-hour video playback claim is backed up by record-setting lab measurements at Notebookcheck and Tom's Guide.
The new triple 48MP rear camera with the bigger telephoto sensor delivers a genuine improvement in 4x/8x reach and detail over the iPhone 16 Pro Max — the closest the iPhone has come to a Pixel/Samsung in flexible zoom.
The laser-welded vapor chamber and aluminum unibody noticeably reduce thermal throttling under sustained load — gaming and ProRes video recording stay cooler and frame-rate-stable far longer than on the iPhone 16 Pro.
The 6.9-inch ProMotion display hits 3,000 nits peak with a new anti-reflective coating, making it one of the easiest phones to read in direct sunlight even if Samsung's S25 Ultra still wins outright on glare.
The A19 Pro is the fastest chip Apple has shipped — 12GB of RAM up from 8GB, multi-core Geekbench around 9,500-9,994, and benchmark wins over the iPhone 16 Pro and Pixel 10 Pro XL.

Detailed Comparison

Battery & Charging

iPhone 17 Pro Max

The Pro Max's 4,823 mAh battery (5,088 mAh on the eSIM-only model) is the largest Apple has ever shipped, and Apple's 39-hour video playback claim is the longest battery life ever on any iPhone. Notebookcheck calls it a battery-life record-setter, Forbes gets 13-14 hours of heavy outdoor use with 20% to spare, and Ars Technica found overnight standby drop minimal. The flip side: GSMArena's web-browsing test actually came in shorter than the 16 Pro Max (a Liquid Glass / iOS 26 issue some suspect), and a heavy r/iphone user reports no meaningful upgrade over a fresh-battery 14 Pro Max. Wired charging finally goes to 40W, wireless to 25W via Qi2 with built-in magnets.

Apple's 4,823 mAh battery on the Pro Max is the largest ever in an iPhone, and the company claims 39 hours of video playback — the longest battery-life claim Apple has ever made for any iPhone.
The iPhone 17 Pro Max sets new battery-life records — Apple has put together a very convincing package and battery endurance is now the clear benchmark for the entire industry.
The Pro Max can last a heavy 13-14 hour day outside with continuous use and still have over 20% left at the end — genuine all-day battery for the first time on a Pro iPhone.

Wired charging finally jumps to a real 40W (50% in 20 minutes with a 40W+ adapter) and wireless to 25W via the new Qi2 standard with built-in MagSafe magnets — the first time iPhone charging speed feels competitive.

The new 18MP Center Stage square selfie sensor is the most-praised camera feature of the generation — automatic portrait↔landscape switching, AI framing, and dual-capture all work as described.

Base storage doubles to 256GB at the same $1,199 starting price, with a new 2TB option exclusive to the Pro Max — high-time storage relief that Apple is finally not nickel-and-diming.

Deal Breakers

At 233 grams it is one of the heaviest non-folding flagships on the market and a step backward from the lighter titanium iPhone 15/16 Pro Max — Ars, Wired and 9to5Mac all flag the heft as the first thing you notice.
Aluminum is much softer than titanium or steel, and 'scratchgate' is real — independent iFixit testing confirmed anodization flakes on the camera-bump edges, and a vocal r/iphone contingent reports visible marks within weeks of caseless use.
Apple Intelligence is still essentially absent — reviewers from Wired, Trusted Reviews, TechCrunch, 9to5Mac and Reddit users all flag that Siri remains useless and the AI story is a generation behind Gemini and Galaxy AI.
The two-tone aluminum-and-glass design with visible camera-cutout seams is divisive — Ars Technica, Forbes commenters, and an r/gadgets thread all call the back 'unfinished-looking,' 'lumpy,' or 'not Jony Ive's iPhone' design language.
The 'optical-quality' 8x zoom is actually a digital crop of the 4x 48MP sensor, not true periscope optics — Vivo, Xiaomi, Honor and the Pixel 10 Pro XL still capture more detail at long range with real periscope hardware.
Reception-quality issues with the new N1 wireless chip — Reddit r/apple and r/iphone owners report Bluetooth audio dropouts in cars and AirPods Pro 3 disconnects that didn't happen on the iPhone 16 Pro Max.

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

After forgetting to plug it in overnight, the Pro Max still had 30 percent charge by morning — enough that you don't have to think about the battery at all anymore.

Got more than 5 hours of screen-on time consistently and 55% left in the tank — the Pro Max battery is now good enough that you might not have to charge it every day.

Wired charging hits a real 40W with Apple's new Dynamic Power Adapter — 50% in 20 minutes, and a full charge in about an hour. The first time iPhone charging speed feels competitive with Android.

Wireless charging jumps to 25W via Qi2 with built-in MagSafe magnets — the first iPhone to natively support Qi2 magnets rather than requiring a magnetic case like Samsung still does on the S25 Ultra.

GSMArena's lab measured web-browsing battery life actually *shorter* than the iPhone 16 Pro Max — the headline 'battery king' claim only holds in video playback and gaming, not all workloads.

Battery life is not as impressive as everyone says — heavy real-world usage on a UK physical-SIM unit shows no noticeable improvement over an iPhone 14 Pro Max with a fresh battery.

After four years on an iPhone 13 Pro Max, the Pro Max battery feels infinite — even on a heavy NY trip with photo and navigation use, it wouldn't drop below 85% by end of day.
