What are the iOS 18 System Requirements for Upgrade?

To upgrade older iPhones to iOS 18, several iOS 18 system requirements have been set, focusing mainly on hardware specifications. The requirement is that devices should at least run on the A12 Bionic chip.

System Requirements Overview

Minimum Chip Requirement: It requires an A12 Bionic chip or later.
Storage Space: Users must have between 5GB and 10GB in free storage space for the update.
