PCMag put the slab and the fold on the same spec sheet dated September 28. Same iOS 27. Same A20 Pro. The 18 Pro starts at $1,199. The Duo starts at $1,999, an $800 jump PCMag calls out in plain English. CNET has the Duo on sale October 23, preorders October 16. MakeUseOf spent weeks on a Galaxy Z Fold 8 and still used it as the stick to hit the Duo.
We already ran Pixel 11 Pro against this same 18 Pro and Z Fold 8 against an iPhone fold. This pairing is Apple’s own fork: the phone they can test for almost 24 hours versus the phone whose battery line still says TBD.
The extra $800 is the hinge
18 Pro storage prices from PCMag: $1,199 for 256GB, $1,399 for 512GB, $1,599 for 1TB, $1,999 for 2TB. Pro Max starts at $1,299 for 256GB. The Duo starts at $1,999 for 256GB, $2,199 for 512GB, then $2,599 at the next step PCMag listed before the extract cut off. PCMag’s prose is the useful part: the Duo carries an $800 premium over the base 18 Pro.
That $800 is not a camera upgrade. The 18 Pro is the one with four rear/front sensors in the table. The Duo is the one that folds. If you want a bigger inner panel and a shorter folded footprint, you are shopping the hinge. If you want the tested endurance and the extra lenses, you are shopping the slab. Mixing those sentences is how a fold demo becomes a $2,000 regret.
CNET’s calendar matters if you preorder out of habit. October 16 to order, October 23 to buy. The 18 Pro is already a shipping product in these reviews. Waiting six weeks for a TBD battery is a choice. It is not a default.
Last year’s 18 Pro tax is also on the PCMag con list: $100 more expensive than the previous model, and it can get hot under processor load. Neither of those is a reason to jump to the Duo. They are a reason to look at the Pixel comparison we already published if the slab is the job and the logo is not.
The Duo is a passport, not a Max
PCMag’s dimensions are the argument you can hold. 18 Pro: 5.91 by 2.83 by 0.34 inches, 6.3-inch panel, 2622 by 1206. Duo folded: 4.64 by 3.31 by 0.44 inches. Unfolded: 4.64 by 6.48 by 0.21 inches. Inner panel 7.6 inches at 2670 by 1878.
The folded Duo is shorter and wider than the Pro. Pocket feel will not match a slab you already own. CNET calls both the Duo and the Z Fold 8 a squat, passport-style book fold, not the tall book some older folds used. If your current phone is a Pro Max, the Duo is a different rectangle, not a bigger Pro.
MakeUseOf’s weight aside is about the Max, not the Pro, but it is still the number people will quote. iPhone 18 Pro Max at 249 grams. Galaxy Z Fold 8 at 201 grams and 9.7mm thick. 18 Pro Max at 8.75mm. The Fold 8, in that telling, packs a 7.6-inch inner panel in a body about a millimeter thicker than the Max when folded. The Duo’s folded thickness in PCMag is 0.44 inches, which is a fatter sandwich than 8.75mm. If thin-when-shut is the reason you wanted a fold, the Samsung is the one MakeUseOf still prefers after weeks of use.
Do not buy the Duo because the unfolded 0.21-inch inner body looks like a magazine in a render. You carry the 0.44-inch folded body.
Four cameras versus two
PCMag’s camera line for the 18 Pro is 48MP, 48MP, 48MP, and a 25MP front. The Duo is 48MP and 48MP on the back, 12MP on the front. CNET matches the Duo as 48 megapixel main and 48 megapixel ultrawide, 12 megapixel selfie on the cover, and no megapixel count for the under-display inner camera.
CNET is blunt about the trade. Compact folds scale back cameras. Telephoto and higher-megapixel stacks stay on pricier folds such as a Z Fold 8 Ultra, or on high-end slabs such as the 18 Pro. If the 5x job is why you own a Pro, the Duo is a step down even before the hinge. We already treated the 18 Pro’s extra money as camera blades against a Pixel. Dropping to two 48s to get a fold undoes that argument.
PCMag’s 18 Pro pros list is the same idea in editor voice: superb cameras with manual controls, plus a more durable front display than its predecessor. The Duo does not get that paragraph. It gets a TBD battery and a 12MP selfie.
If you fold mainly for reading and a bigger keyboard, two 48s may be enough. Say that out loud. Do not pretend the Duo is the 18 Pro with a hinge.
23 hours 45 minutes versus a footnote
PCMag tested the 18 Pro at 23 hours and 45 minutes. The Duo battery is TBD. CNET, without a lab number, repeats Apple’s marketing hours. Typical use up to 24 hours, about the same listed figure as the 18 Pro. Outer display: up to 44 hours watching video, 37 hours streaming. Inner: 31 hours watching, 26 hours streaming. Capacity in milliamp-hours is not on the public spec sheet, which CNET notes is typical for Apple.
Marketing hours are not PCMag’s 23:45. The slab has a test. The fold has a brochure split by which screen you used. Until someone repeats the PCMag test on a Duo, the endurance winner is the phone with a stopwatch. That is the 18 Pro.
MakeUseOf gives the Duo MagSafe, IP68, Apple Pencil support, and a vapor chamber for the A20 Pro, and says those extras can justify being $100 above the Z Fold 8. Those are fold-vs-fold points. They do not fill in TBD against a slab that already lasted 23 hours 45 minutes in a lab.
Heat is the 18 Pro’s listed con. A vapor chamber on the Duo is interesting if you fold for long sessions. It is still not a tested runtime.
The Fold 8 is the other fork
This column is 18 Pro vs Duo. The internet will not let it stay that way. CNET’s whole piece is Duo vs Z Fold 8. MakeUseOf’s whole piece is why the Fold 8 still wins five ways after real use, while granting the Duo MagSafe, IP68, Pencil, and the chamber.
Z Fold 8 at $100 less than the Duo, 201 grams, 9.7mm, free screen protector replacement in MakeUseOf’s telling. If your alternative to the 18 Pro is “I want a fold,” you still have to pick a fold. Apple’s first one is late, squat, and $1,999. Samsung’s current one is the device a reviewer actually carried for weeks.
If your alternative is “I want the iPhone I already know, with this year’s cameras,” the 18 Pro is the product that exists on a spec sheet with a battery test. The Pixel 11 Pro Fold pairing is a different week. Do not collapse four SKUs into one cart.
Pencil and MagSafe do not fill TBD
MakeUseOf is the piece that actually tries to like the Duo. It calls the $2,000 tag almost reasonable against foldable prices and a RAM shortage, then lists MagSafe charging, IP68, Apple Pencil support, and the vapor chamber as the extras that can justify $100 over the Z Fold 8. Those extras are real if you already live in Apple’s cables and cases. They are not a battery test. They are not a telephoto. They are fold-versus-fold concessions.
IP68 on a first Apple fold is the durability claim reviewers will try to break in November. Until then it is a spec. The 18 Pro’s more durable front display, in PCMag’s pros, is a claim about a phone you can buy this week. Do not preorder a hinge because the slab’s glass got better.
Apple Pencil on a phone is a niche you should be able to name. If you do not currently draw on an iPad in a meeting, you will not start on a 7.6-inch inner panel that you also use as a phone. MagSafe is the more honest extra: the case ecosystem you already own. That still does not make the Duo an 18 Pro.
Pro Max storage in PCMag goes to $2,499 for 2TB. The Duo’s 256GB floor is already $1,999. If your reason for 2TB is video, the cameras on the Pro still win. If your reason is “I do not want to think about storage,” 256GB at two thousand dollars is a stingy floor for a fold.
Buy the slab unless the hinge is the job
Winner: iPhone 18 Pro. It is $800 cheaper at the floor, it has the camera stack, and someone timed the battery at 23 hours 45 minutes. The Duo is a first-generation passport fold with a 7.6-inch inner panel, a 12MP cover selfie, and a ship date of October 23. If you need that inner panel and you want MagSafe and IP68 on a fold, wait for the tests. Do not preorder on October 16 because the keynote folded.
Outer-screen video hours in CNET’s brochure (44 watching, 37 streaming) are the number people will repeat in comments. They are not PCMag’s lab run. Inner-screen 31 and 26 are even easier to misuse, because nobody carries a fold open all day. Until a lab repeats the 18 Pro test on a Duo, treat Apple’s hours as advertising split by display.
If $1,199 is already more phone than you use, the $100 jump versus last year’s Pro is the fight, not the hinge. If $1,999 is acceptable only as a fold, read the Fold 8 pieces next, not this one a second time. MakeUseOf already did the weeks of pocket time. PCMag already did the slab stopwatch.
The A20 Pro is in both. It will not save a purchase you made for the wrong rectangle. Heat on the 18 Pro under load is a real con in PCMag’s list. It is still a cheaper, better-camera, already-tested phone. Wait for the Duo’s TBD to become a number. Then rerun this comparison if the hinge was actually the job.
Preorder day is October 16. If you are still arguing with yourself on October 15, you do not need a fold. You need the 18 Pro, or you need to wait for a lab number that does not exist yet. CNET’s “typical use up to 24 hours” line is easy to paste next to PCMag’s 23:45. One is Apple’s brochure. The other is a test. Keep them in separate cells of the table.
