For those who have yet to place their order and are still holding off on doing so, you might be interested to learn that supply could ease up in the coming months. This is according to a DigiTimes report (paywall) where they claim that the shortage of components is starting to ease up and that things should be easier come February 2022.
According to the report, “The shortage of IC components emerging in early October for iPhone 13 series is gradually easing as suppliers increase production, with assemblers on track to step up manufacturing through next February to meet terminal demand, according to supply chain sources.”
Right now from what we can tell, the iPhone 13 mini and iPhone 13 models are seeing an estimated shipping time of 5-7 days, but the higher-end iPhone 13 Pro and Pro Max models are seeing shipping estimates of 3-4 weeks.
