The iPhone Duo puts two apps side by side in a pocketable device, but it is not simply a better iPhone Pro. Check your essential apps and camera needs before paying the folding-screen premium.
From announcement to sale
Apple’s first folding phone, the iPhone Duo, went on sale October 23, including in the United States, after its September announcement. A 5.4-inch outer screen opens into a 7.6-inch display, providing more room for documents, photographs and two applications at once.
Apple’s announced U.S. starting price is $1,999 before tax for 256GB, checked October 25. This is a phone-only launch price, not a sale or a delivery promise. Tom’s Guide reported extended backorders during its review. Check your exact configuration’s delivery estimate; carrier credits and leases are not equivalent to an outright discount.
The useful part is working across two apps
Apple calls the two-app arrangement Split View: one application sits beside another on the open screen. You could keep a message visible while consulting a webpage, instead of repeatedly switching between them. Compatible apps can also display two windows.
In independent hands-on testing, Tom’s Guide found the split-screen controls easy to use, but reported that turning the device into portrait orientation interrupted the side-by-side arrangement. Its October 22 review also found some third-party apps poorly adapted to the display. Software can change after launch; test your own must-have apps rather than assuming every app fills the screen well.
More screen does not improve everything
Digital Camera World’s separate October 23 hands-on report found the open screen attractive for browsing and viewing still photographs, but noted that widescreen video still carries black bars. A larger display measurement therefore does not automatically mean a dramatically larger movie image.
The hardware compromises are more lasting. The Duo uses a fingerprint sensor rather than Face ID and lacks a dedicated telephoto camera. Tom’s Guide’s image comparisons found weaker detail at long zoom than the iPhone 18 Pro Max. Its controlled web-browsing test lasted 13 hours 20 minutes using the inner display; that is a laboratory result, not a guarantee of your daily battery life.
What to check before ordering
Try typing, unlocking, rotating and opening your essential apps on a demonstration unit if possible. Compare the actual tasks you gain with the camera capabilities and handling you give up. Apple describes USB-C Apple Pencil support as coming later this year; do not purchase on the assumption that a promised feature is already available.
