iPhone Ultra supply will be very limited when the foldable device is first released later this year, according to Fixed Focus Digital, a known leaker on the Chinese social media platform Weibo. The account also claimed that the iPhone 18 Pro's A20 Pro chip will be up to 18% faster and up to 30% more power efficient compared to the iPhone 17 Pro's A19 Pro chip. The A20 Pro chip will be the first iPhone chip manufactured with TSMC's 2nm process, rather than the current 3nm process.

Apple's annual iPhone event is likely less than a month away. This September, Apple is expected to unveil the iPhone 18 Pro, iPhone 18 Pro Max, and an all-new foldable iPhone that will reportedly be named the iPhone Ultra.

The regular iPhone 18, a lower-end iPhone 18e, and the iPhone Air 2 are not expected to debut at the same event. Supply constraints for the iPhone Ultra may limit availability at launch.

These details come as anticipation builds for Apple's highly anticipated product announcements.
