The iPhone 12 is a little slow to charge, and the power chip is not enough

At 21:00 p.m. on November 6, apple officially opened the reservation of iPhone 12 mini and iPhone 12 Pro max. users can purchase mobile phones on Apple’s official website and major e-commerce companies. Before the launch of sales, pro Max had more than 1 million reservations in Jingdong alone, while the mini had 600000. The official launch date of the two new models is November 13. < p > < p > but after the 21:00 sale, Apple’s official website has been seriously jammed or even collapsed. The apple mobile phone, which starts at 9299 yuan, has been popular among people. According to foreign media reports, a person familiar with the matter, who did not want to be named, said Apple was facing a shortage of “power management chips” for iPhones and other devices, which may further strain the supply of the iPhone 12. In a recent conference call with analysts, Apple CEO Tim & middot; cook warned that the supply of the iPhone 12, MAC, iPad and some apple watch models would be restricted. However, he did not specifically mention power management chips. The power chip plays an important role in the mobile phone. Because the working voltage of each module of mobile phone is different, the voltage directly supplied by battery can not meet the requirements of each module. At this time, the voltage regulation of power management chip plays an important role in the stable operation of the whole system. < / P > < p > it’s not clear to what extent the iPhone 12 supply will be limited in the critical release season. In the United States, Apple’s official website shows that orders for the new iPhone 12 Pro won’t reach customers until the end of November or early December, while the regular iPhone 12 will not be delayed. Many iPad models will be delivered between mid November and the end of the month, while some apple watch models will be delivered in late November. < / P > < p > but power chip suppliers may give priority to apple and the power hungry iPhone 12 over other customers, sources said. He believes that the supply shortage is mainly due to the supply chain disruption caused by the epidemic and the increase in silicon demand for various products. < / P > < p > compared with ordinary mobile phones, the demand for power chips in the iPhone 12 is greater. “Compared with 4G, 5g smartphones require 30% to 40% more chips. TSMC, the main supplier of apple chips, once said, “and the uncertainty of the epidemic has made many manufacturers hoard goods because of the fear of insufficient parts. “< / P > < p > although the global electronics industry has gradually recovered from the epidemic, the problem of insufficient supply has been exacerbated by a large number of manufacturers’ hoarding. The supply shortage is expected to continue for another two quarters, the person familiar with the matter said. < / P > < p > and considering the extra camera and 5g features, power management is more important in the iPhone 12 than in other iPhone series. Apple recently launched four 5g models and analysts expect strong consumer demand for the device. Cook said the iPhone supply problem was “not surprising” as apple was just beginning to increase production. “It is difficult to predict how long the supply constraints will last. “He added. < / P > < p > according to the disassembly report of ifixit, a company that publishes DIY repair and disassembly guidelines for electronic products, there are many power management chip suppliers for the iPhone 12 pro. For example, the camera control system is powered by Texas Instruments, and 5g modem chips are from STM and Qualcomm. < / P > < p > it is worth noting that Apple’s self-developed power management chip has also appeared in the iPhone 12 pro. In 2018, apple acquired dialog, a European chip maker for us $600 million, to start manufacturing its own power management chips. < / P > < p > in China, IC power management chips are also facing the problem of “neck sticking”. 80% of the market is monopolized by Europe and the United States, but some start-up companies are also receiving capital attention. For example, Nanxin semiconductor, with buck boost as its core, has obtained more than 100 million yuan of round C financing from Xiaomi group, Sequoia Capital China and oppo. < / P > < p > finally, although the iPhone 12 has been snapped up in China, the outside world is also questioning whether Apple can remain competitive in China at a time of supply chain problems. After all, in Apple’s soon released fourth quarter report, Apple’s sales revenue in Greater China fell 28.6% year-on-year, a new low since 2014.
