In relation to downloading iOS software program updates, Apple customers will be fairly divided into two camps: Those that manually hunt down updates the second Apple releases them, and those that are completely happy to let their system’s Automated Updates characteristic deal with every little thing within the background with minimal enter on their half.
Whereas it is typically acknowledged that manually tapping into Settings -> Normal -> Software program Replace is the sooner choice, Apple has by no means actually defined why auto-updates have a tendency to come back by means of to customers generally days and even weeks later – till now.
iPhone person Mateusz Buda put this query in an electronic mail to Craig Federighi, Apple’s senior VP of software program engineering. Within the electronic mail, Buda defined that he had turned on auto-updates, and but after two weeks because the public launch of iOS 15.4 he nonetheless hadn’t acquired an replace notification. “What circumstances should be met for this perform to work?” Buda requested. To his shock, Federighi responded and was completely happy to elucidate.
We incrementally rollout new iOS updates by first making them obtainable for those who explicitly search them out in Settings, after which 1-4 weeks later (after we have acquired suggestions on the replace) ramp as much as rolling out gadgets with auto-update enabled.
Hope that helps!
Given the variety of iPhones and iPads on the earth, it is not massively stunning to listen to that Apple’s software program replace technique proceeds in a staged rollout. By implementing an intentional delay of between 1-4 weeks for customers with auto-updates turned on, Apple provides a degree of safety for its servers so they are not simply overloaded when a brand new model of iOS is launched.
Nonetheless, it is fascinating to be taught that Apple additionally considers its auto-update characteristic to be a safeguard when issues go improper: If early adopters report severe bugs with the software program, Apple nonetheless has a window of alternative to resolve any server-side points or pull the replace solely earlier than the broader person base has mechanically downloaded it.
In a considerably associated level, made by a number of Redditors, Apple hasn’t defined why some app auto-updates are additionally generally very late to be delivered to customers, however maybe the reasoning is identical: Server safety and a capability to motion suggestions earlier than a wider rollout is full.
