My coworkers spent years giving me grief about my foldable, and? They weren’t flawed—early hinges felt like high-school science initiatives. However now Apple has launched the iPhone Duo, full with an absurdly complicated 100-plus-part hinge, abandoning twenty years of treating the inflexible slab like sacred scripture. Counterpoint thinks Apple will ship six million of the iPhone Duo in 2026. That places them in second place behind Samsung, nearly a decade late to the get together, however no one shopping for one goes to care in regards to the timeline.
Fast verdict
Present Apple customers will really feel proper at house on the iPhone Duo—it’s basically an iPhone that opens up into an iPad mini. If you happen to hate heavy telephones and need one thing that’ll final seven years, get the Galaxy Z Fold. The Xiaomi 18 Fold is the most effective digicam telephone of the group, assuming you should buy one the place you reside.
The display screen you utilize with the telephone shut
The iPhone Duo feels extra convincing when it’s closed, and that has much less to do with the panel itself than with what Apple does round it. The outer show is 5.4 inches and covers 90% of the display screen space on an iPhone 18 Professional. Extra importantly, each shows use the identical side ratio. Open the telephone and the format expands as an alternative of forcing every thing into a brand new form. Apple additionally rebuilt iOS 27 across the Duo relatively than merely stretching the common iPhone interface throughout a bigger display screen.
With Xiaomi, protecting each shows near A4 proportions works nicely for paperwork, whereas 16:9 video fills the display screen with out trying awkward. Samsung pushed the Fold8’s cowl display screen to five.5 inches, which is wider than earlier Folds, however vertical video can nonetheless depart black bars on both facet, and a few feeds minimize off textual content close to the highest. For sure, that’s irritating on a telephone you’re purported to unfold when the smaller display screen will get in the way in which.
Zoom attain and the lens no one packed
I’m baffled that Apple and Samsung each cheaped out on telephoto glass right here. The Duo depends on a 2x sensor crop, and the Z Fold’s digital zoom turns photographs right into a blurry mess the second you go previous 4x. Xiaomi is taking part in a distinct sport—sticking a 50 MP periscope on the 18 Fold alongside that large 200 MP predominant sensor. If you happen to shoot long-range photographs, there’s just one selection.
Apple is leaning on software program to distract from the Duo’s lacking zoom {hardware}. Options like Good Take (which waits for motion to cease earlier than capturing) and Child Cue (which performs animations to catch a toddler’s eye) are intelligent additions for every day snapshots. However none of those sensible options compensate for the entire lack of optical zoom once you want distance.
The Xiaomi 18 Fold takes the digicam criterion by a distance, and no quantity of computational cleverness closes the hole.
Stamina in hour three
I play Name of Responsibility on my telephone from the couch. Draw your personal conclusions about my priorities. Apple wins the criterion, narrowly and particularly. A20 Professional bonds to a customized vapor chamber, and the declare is as much as 35% higher sustained efficiency than the iPhone 17 Professional managed. Samsung packed the Snapdragon 8 Elite Gen 5 behind 4,800 mAh in a 4.5 mm physique, leaving cooling nowhere to go.
Xiaomi owns the battery division right here. Its 6,000 mAh silicon-carbon cell merely outlasts the sphere, whereas 67 W charging will get you again up and operating rapidly. Apple likes to brag about “31 hours of video playback” on the Duo, however taking part in regionally saved recordsdata barely makes a telephone work. It tells you just about nothing about how the battery survives a chaotic day of mobile information, location monitoring, and digicam use.
How a lot belief the hinge earns
On the subject of foldables, water will get all of the advertising buzz, however pocket lint is what destroys hinges over time. That’s why Apple’s IP68 score on the Duo is a big deal—it retains nice mud out fully, not simply water.
Samsung’s IP48 score leaves the inside open to small particles, whereas Xiaomi claims IP58 and IP59 safety on its Chinese language spec sheets however mysteriously leaves any point out of ingress rankings off its international launch supplies.
The place the iPhone Duo wins
The Duo’s largest energy is that iOS lastly does split-screen with out feeling clunky. Having Netflix on one facet and Slack on the opposite really works out of the field as a result of builders optimized their layouts earlier than launch—a stage of app help Android foldables nonetheless battle to get. Transferring Contact ID to the facility button was additionally the best name, providing you with a quick, constant unlock irrespective of the way you’re holding the system.
Bringing Apple Pencil help to the Duo offers Apple a large benefit over Samsung, which puzzled college students, artists, and digital artists after eradicating stylus compatibility from the Fold sequence.
The place the Galaxy Z Fold8 wins
Weight is the place the Fold8 takes a lead. At 201g, it’s about 18 grams lighter than the Xiaomi—and that’s a distinction you discover when holding it one-handed on the finish of the day. Samsung additionally guarantees seven full years of Android and safety updates. On a telephone with a posh mechanical hinge that takes every day put on and tear, having assured software program help that far out into the longer term ought to provide you with peace of thoughts.
The place the Xiaomi 18 Fold wins, with an asterisk
Xiaomi leads the pack on sheer processing headroom. That further horsepower is most evident in HyperOS 4’s multiwindow mode, which squeezes 4 reside app panes onto the 7.58-inch show directly. In your info, opponents like Samsung and Apple cap their split-screen modes at two or three apps to save lots of reminiscence.
Availability is the half that will cease me from shopping for the 18 Fold. There’s no official worldwide launch, so exterior China you’re gray-market sellers. That brings a couple of issues I wouldn’t wish to take care of on a foldable. The Chinese language model might not help all of the LTE and 5G bands your provider makes use of, and the software program is constructed round Chinese language providers. Then there’s the guarantee. If the inside show develops an issue, it’s possible you’ll be left with out native protection and going through the trouble of sending the telephone again.
Ultimate verdict
The iPhone Duo is my most secure suggestion for current iOS customers. Apple delivers a refined multiwindow expertise out of the field, backed by mud and water safety that neither Samsung nor Xiaomi ensures on paper.
Samsung’s Galaxy Z Fold8 stays the higher decide for patrons prioritizing weight discount and long-term OS help, however the final trade-off stays sensible utilization. In case your workflow doesn’t require open-tablet multitasking, shopping for any premium foldable is an costly overcorrection.
