Apple Inc is grappling with a shortage of vital chips that manage power consumption in iPhones and other devices, people with knowledge of the matter said, complicating its ability to meet holiday demand for the latest version of its marquee gadget.
It is unclear to what extent the bottleneck might limit iPhone availability during its crucial launch quarter, typically Apple’s busiest.
Despite the shortfall, suppliers are likely to prioritize Cupertino, California-based Apple and its power-hungry iPhone 12 over other customers lining up for scarce parts, said the people, who asked not to be identified discussing private matters.
Increasing demand for silicon across a range of products and supply-chain disruptions from COVID-19 are the main causes of the shortage, the people said.
Main Apple chipmaker Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) last month said that 5G smartphones require 30 to 40 percent more chip content versus 4G. That and uncertainty over the course of the pandemic is spurring customers to cache components for fear of running out, especially after major smartphone maker Huawei Technologies Co (華為) had stocked up massively ahead of a September deadline for US sanctions.
The stockpiling compounds lingering issues across a global electronics industry still recovering from rolling lockdowns that snarled transport routes and cut off workers from factories earlier this year. Disruptions are expected to persist over the next two quarters, the people said.
Power management is more important in the iPhone 12 than for its predecessors given additional camera features and 5G capabilities, increasing Apple’s need for these components. It recently launched four 5G models and analysts expect strong consumer demand for the devices.
During a recent conference call with analysts, Apple CEO Tim Cook warned about supply constraints for the iPhone 12, Mac, iPad and some Apple Watch models — although he did not specifically mention power-management chips.
Supply issues for the iPhone are “not a surprise” because Apple has just begun to ramp up production, Cook said.
“It’s hard to predict” how long the supply constraints will last, he added.
An Apple spokesman declined to comment.
Apple has multiple power management chip suppliers, according to a recent teardown from iFixit. The iPhone 12 Pro uses a component from Texas Instruments Inc to control power to the camera system, along with a similar chip from STMicroelectronics NV and one from Qualcomm Inc for the 5G modem.
There is also a power-management part designed by Apple in this handset. In 2018, Apple acquired technology and other assets from Dialog Semiconductor PLC for US$600 million to build its own power-management chips.
The disruption to iPhone production comes amid questions over Apple’s ability to galvanize demand for its newest gadget in China, following its worst quarterly revenue performance there since 2014.
Investors are concerned the company is losing momentum to homegrown rivals like Huawei and Xiaomi Corp (小米) in one of its most critical markets.
With the speed cryptocurrency is emerging as the millennial generation’s alternative asset of choice in India, it is hard to imagine that just two years ago a couple of blockchain pioneers were briefly in police custody. Sathvik Vishwanath and Harish BV, cofounders of a then five-year-old start-up, were arrested in late 2018. No, they had not pulled off a shady initial coin offering. Their “crime” was that they put up a kiosk in a mall in Bangalore where customers could swap bitcoin, ether or ripple for cash or vice versa. That was the whole point of unocoin, their crypto token exchange.
FIVE NEW FABS: An acquisition of Siltronic would boost GlobalWafers’ market share from 17 to 30 percent, easily surpassing Japanese rival Sumco’s 25 percent GlobalWafers Inc (環球晶圓) yesterday said it is in final talks to acquire Germany-based Siltronic AG in a 3.75 billion euro (US$4.5 billion) deal, which might help it compete with its closest rival Sumco Corp of Japan. The acquisition would be the fifth for GlobalWafers since 2008, as it has grown to become the world’s No. 3 supplier of silicon wafers through such deals. GlobalWafers, which has a 17 percent market share, would see its market position greatly elevated to 30 percent when combined with Siltronic’s 13 percent, according to a presentation Siltronic gave to its investors at a quarterly conference in August.

A Chinese factory owned by South Korean semiconductor giant SK Hynix Inc yesterday halted operations after a plant worker was found to have an asymptomatic infection of COVID-19, Xinhua news agency reported. The South Korean worker based at the plant in Chongqing since February had departed on Thursday for South Korea, Xinhua reported. He was tested at Incheon Airport in Seoul and confirmed positive for COVID-19 on Saturday, it reported. All factory staff as well as staff and recent guests at the hotel where the worker lived have been isolated and given nucleic acid tests, the agency said. “We’re cooperating with the local government
CONCERNS: The bank would act if it noticed currency speculation, the governor said, but he did not comment on a likely trajectory of the NT dollar against the greenback The central bank would intervene in the market whenever necessary to help stabilize the New Taiwan dollar, central bank Governor Yang Chin-long (楊金龍) said yesterday, adding that it is concerned Taiwan might be placed on the US watchlist for currency manipulation. The Control Yuan recently sent letter inquiring about the central bank’s market regulation efforts, Yang told a meeting of the legislature’s Finance Committee on the NT dollar’s appreciation and property price hikes. “It is the central bank’s top responsibility to stabilize foreign exchanges,” he said. The central bank has often stepped in toward the end of trading sessions to moderate the NT
