The analyst, who has a very good track record in predicting Apple news, is now estimating 11.4 million units shipped in the September quarter. That's a 33% drop from his original 15 million estimate. Kuo also says he expects iPhone 5c sales to be 10.4 million units in the December quarter.
Kuo is still formulating how this will affect Apple overall since the iPhone 5s and iPhone 4s remain strong sellers.
A recent report from CTech said that Apple has cut production of the iPhone 5c in half as sellers in China and in the U.S. drop their prices to increase sales.
