“The facility is currently operating at significantly reduced capacity,” the iPhone maker said in a statement.

“Customers will experience longer wait times to receive their new products,” it added.

Reuters last month reported that production of Apple’s iPhones could slump by as much as 30% at one of the world’s biggest factories next month due to tightening Covid curbs in China.

Its main Zhengzhou plant in central China, which employs about 200,000 people, has been rocked by discontent over stringent measures to curb the spread of Covid-19, with many workers fleeing the site.

Separately, Taiwan’s Foxconn, Apple Inc’s biggest iPhone maker, said today it was working to resume at a major plant in Zhengzhou that had been hit by Covid-19 curbs, and revised down its fourth quarter outlook.

The impact on production comes amid a traditionally busy time for electronics makers ahead of the year-end holiday season, which is also a prime time for vendors of consumer goods like Apple.
