Lengthy iOS 10.3 install time likely due to conversion to new Apple File System
By Mike Wuerthele
Early adopters of the full iOS 10.3 release are seeing lengthy install processes, with multiple device reboots - probably as a result of the shift to Apple's new APFS.
After quick downloads of 600 megabytes and above, early installs witnessed by AppleInsider are seeing install times greater than 20 minutes on several iPhone 7 and iPhone 7 Plus units, with a 12.9-inch iPad Pro taking 27 minutes, and an iPad Air 2 taking about 48 minutes.
