The iPhone Ultra will easily be the star of the Apple September 9 event, eclipsing the iPhone 18 Pro and iPhone 18 Pro Max. That’s because this device will be Apple’s first foldable phone, launching several years after the Android competition.Apple hopes to stand out in several ways, including software and apps that are fully optimized for the foldable experience, a display that’s nearly crease free, and the first 2nm chip in a phone. But it’s expected to have some trade-offs, too. Here’s everything you need to know about the iPhone Ultra.It’s the thinnest iPhone ever

That would make it the thinnest iPhone ever. The foldable could be 9 to 9.5mm when closed.The Galaxy Z Fold 8 is 4.5mm when open and 9.7mm when closed, so the foldable iPhone could be on par with Samsung’s device.You get a 5.5-inch and 7.8-inch screen

(Image credit: Tom's Guide)The whole appeal of the iPhone Ultra is that you’ll get a compact device when closed with a wide 5.5-inch display that’s great for using apps, scrolling TikTok and responding to messages.But when you want a more immersive video and gaming experience you can unfold the phone and get a relatively massive 7.8-inch display. It will have a 4:3 aspect ratio that’s optimized for media, but you’ll be able to flip it around to 3.4 portrait mode for surfing the web and reading.The crease is nearly invisible
