Currently, the most storage offered on iPhones is 512 GB, so an iPhone 13 with 1 TB of storage would be a first for Apple.
Prosser reiterated this prediction in January on Front Page Tech, saying that most of the iPhone 13 high-end prototypes do feature 1 TB of storage.
“We’re in early stages of iPhone 13 right now and we kind of just have prototypes to go off of, which means that not much is actually final,†Prosser said in January.
