Does Baidu Maps work on iPhone Duo?
Not announced yet. Baidu hasn't said when Baidu Maps will get an iPhone Duo layout. It still opens on the Duo, but won't fill the inner display until it's updated.
- Not announcedChina App Store release notes and indexed developer channels checked. No Duo-specific developer announcement found; this is not an on-device test.
Until it's updated
What an app does on iPhone Duo before its developer adapts it. Which of the open cases applies to Baidu Maps depends on the tools its current version was built with, and we haven't seen it on the device.
Closed
On the outer display it looks and works as it does on any iPhone.
Open, built with older tools
An app last built with Xcode 26 sits in an iPhone-shaped window on the inner display, with black borders around it.
Open, built for iOS 27
An app built with the iOS 27 SDK resizes to use more of the inner display, with some space left over.
Open, built for iOS 27.1
Only an app built with the iOS 27.1 SDK reaches the edges of the inner display and moves its bar buttons to the side. Apple calls that “optimized for iPhone Duo”.
About Baidu Maps
As of October 8, 2026 (Pacific Time), the China App Store lists Baidu Maps version 22.0.0, released September 17, 2026 (UTC). Its release notes do not mention iPhone Duo. Our search of indexed pages on the developer’s official site found no Duo-specific developer announcement. This is an announcement search, not an on-device test; sign-in requirements and inaccessible pages limit what we can check.
Baidu Maps will still open on iPhone Duo. Closed, it looks as it does on any iPhone. Open, it won’t stretch across the inner display until Baidu rebuilds it with iOS 27.1 tools. More in how apps that aren’t updated run on iPhone Duo.
