Slower-than-expected demand has reportedly led Apple to direct its top phone assemblers, Foxconn and Pegatron, to halt a planned production boost for iPhone XR, a relatively cost-effective model that hit the shelves late last month.

Foxconn, a Taiwan-based company, would produce around 100,000 fewer units daily to reflect the new demand outlook, down 20-25 per cent from the original optimistic outlook, Japanese financial paper Nikkei reported on Monday citing anonymous sources.
