It's been a tough year for smartphone manufacturers, including Apple. And although "apple" the company has not suffered so much from a global shortage of chips, now there is still some shortage of the new iPhone 13 line.
Apple is doing everything it can to ensure that the shortage of components for the iPhone 13 family of smartphones, which began in October, will reduce. For example, TSMC has reserved many of its production lines for Apple's chips, but even in this case there are not enough processors.
A recent Digitimes report says suppliers are increasing production, but the shortage will still last until next February. By by then, Apple needs to get production up and running to fully meet customer demand.
Incidentally, in a note to investors, CEO Tim Cook said that problems with component supplies cost the company $6 billion last quarter. It's not out of the question that this figure has increased over the last 3 months.
