Everything about the iPhone Duo, in one place
An independent guide to buying, using and caring for Apple's first foldable iPhone.
01
The complete, independent guide to owning an iPhone Duo
iPhone Duo Guide exists to answer every question an iPhone Duo buyer or owner has: which storage tier and color to choose, where to find stock, which cases and apps work with the folding display, how to care for the hinge and screen, and what Apple's service options cost. Our objective is to be the most comprehensive source of iPhone Duo information online, drawing on Apple's documentation, published reporting and reviews, and reports from owners.
iPhone Duo Guide is an independent site and is not affiliated with, endorsed by or sponsored by Apple Inc. When something is confirmed by Apple we say so; when it's a report or a rumor, we label it.

iPhone Duo battery drain: how to see what's using power
iPhone Duo battery drain usually shows up clearly in Settings > Battery, which Apple says flags higher-than-normal use and the apps or activities that may explain it. This guide walks through reading those screens and checking the settings Apple documents, from setup work to StandBy.

Repairs
iPhone Duo third-party repair: warranty, parts and what Apple allows
You can take iPhone Duo to an independent shop, but Apple's warranty excludes damage from outside service, and AppleCare+ won't cover any damage once someone outside Apple's network has opened the phone. iPhone Duo also logs replaced parts in Settings, and as of Nov 13, 2026, Apple's US Self Service Repair Store doesn't list iPhone Duo.

iPhone Duo trade-in deals: who gets the top credit at each carrier
AT&T and T-Mobile put up to $1,200 on iPhone Duo for a trade-in as of Nov 13, 2026, but each decides who gets the top credit differently. Verizon's iPhone Duo and deals pages show no trade-in amount. Here's which phones and plans qualify, and how it compares with Apple Trade In.

How-To
How to shoot hands-free with iPhone Duo half-open
iPhone Duo can stand on its own half-open, and Apple builds Smart Take, Duo Preview, Kid Cue and hands-free FaceTime around that. Here's what Apple documents for each pose, how to set up a group photo, a time-lapse and a video call, and where reviewers found limits.

Apps
Best emulators for iPhone Duo
Delta 2.0 is the only emulator whose App Store listing names iPhone Duo, with DS layouts built around the fold. PPSSPP, Gamma, Folium, RetroArch and Provenance should run on paper, but their listings don't mention the Duo as of Nov 13, 2026.

Comparisons
iPhone Duo vs Honor Magic V6
Honor's Magic V6 launched in China, Malaysia, the UK and Germany in 2026, but Honor doesn't officially sell it in the US. On paper it is thinner, lighter and has a 3x telephoto, while Apple's iPhone Duo counters with 6-meter IP68 water resistance, MagSafe and a 2TB tier.
