With the iPhone Air and iPhone 17 Pro lineup, Apple shipped a major upgrade alongside the A19 Pro chip – 12GB of unified memory. That’s 50% more than the iPhones that directly preceded it, and double what iPhones offered just a couple years ago.
However, the base iPhone 17 with its A19 chip missed out on this upgrade – still sticking with 8GB of unified memory. According to one report from The Bell (via MacRumors), though, that might change with the next model.
