iPhone Duo AMA answers reveal charging and screen-use limits
Apple’s first folding phone, the iPhone Duo, drew many questions after a reviewer hosted question-and-answer sessions on Threads and X. The reviewer said opinions are divided over features including the lack of Face ID and a telephoto camera.
The unfolded phone can slowly rotate on a MagSafe charging stand because its weight is uneven, so the reviewer advises against charging it that way.
Its back is also too short for a standard MagSafe Wallet.
A vertical wallpaper can show more of the image when the phone opens, spanning the outer and inner displays.
The Duo can show two apps side by side and move content between screens, but it cannot run more than two apps at once or show the same app on both screens.
The Books app is optimized for the device, while Kindle was not optimized in the reviewer's test.
TechRadar’s Lance Ulanoff found that an unfolded iPhone Duo slowly rotates on a MagSafe charging stand because its weight is unevenly distributed.
The phone’s back is too short for a standard MagSafe Wallet.
The Duo supports split-screen use with up to two apps, and users can drag and drop content between screens.
Ulanoff said the same app cannot run on both screens at once, though TikTok and Instagram Reels can run side by side.
He answered questions about the device in AMAs on Threads and X over 24 hours.

What people are saying
So, while you could use the unfolded Duo on a MagSafe charging stand, it is not recommended.
The Duo's back is too short to accommodate the standard MagSafe Wallet.
You cannot, but if you want to maximize your social media, I found that you could run TikTok and Instagram Reels in side-by-side windows.
