Apple has reportedly shifted more of its orders for the iPhone XR to Foxconn Electronics from Pegatron, as the latter has seen its production slowing down due to capacity constraints and delayed shipments of some key components, according to a Chinese-language Economic Daily News (EDN) report.

Apple had originally split its orders for the LCD-based iPhone XR mainly to Pegatron and Foxconn, with the former landing 50-60% of the total orders and the latter taking about 30%, said the report.

However, Apple has recently lowered the portion of the iPhone XR orders dedicated to Pegatron to below 30%, while ramping up those to Foxconn substantially, said the report, which added that Pegatron's production has been affected by a lower-than-expected yield rate and shortages of workers at its plants in China.

Additionally, the supply of LCD panels from Japan Display (JDI) for the production of the iPhone XR has not been steady, noted the report.

Both Pegatron and Foxconn have declined to comment on the report.

Apple will begin to accept pre-orders for the iPhone XR from October 19 and to deliver the orders on October 26.
