In 2019, the iPhone, which has always been positioned as a high-end product, began to take the people-friendly route. With the hardware upgrade, the price of the iPhone 11 is 1000 yuan lower than that of the iPhone XR, reaching 5499 yuan, making it a high-performance iPhone. Thanks to its low price, the iPhone 11 has become a popular model and won the global single product sales champion for many times. In the first half of 2020, it sold 37.7 million units. < p > < p > at the apple autumn chip Conference on September 16, A14 chip has been unveiled. According to Apple’s official introduction, the A14 chip adopts TSMC 5nm technology, with two large cores and four small cores. Compared with A13 chip, the performance of CPU and GPU is improved by 40% and 30% respectively, and the 16 core neural network unit and machine learning ability are improved by twice. < p > < p > from the data listed, the upgrade of A14 chip is very fierce, and it is the most powerful mobile terminal processor in the world. It is worth noting that apple can obtain 10 million A14 chips in the third quarter, 70 million A14 chips in the fourth quarter, and 80 million A14 chips this year. < / P > < p > the digital blogger infers that Apple will produce about 70 million iPhones this year. Although the shipment volume is not equal to the sales volume, it is not difficult to see from the above data that apple is very confident in the sales of the iPhone 12. However, the sales of the iPhone 12 series will not be known until it is on the market. < / P > < p > in addition, it has been reported from many sources that the starting price of iPhone 12 is consistent with that of iPhone 11, and the starting price of BOC version is 5499 yuan. But the owner said that the probability is very low. After all, the profit margin of iPhone has always been very large, and the cost of the iPhone 12 has increased a lot. The bill of materials of the whole machine has increased by nearly $50, about 338.3 yuan. < / P > < p > although it was previously reported that the battery capacity of the iPhone 12 will be reduced from 3110 MAH of the iPhone 11 to 2227 MAH, and Apple will cancel the free gifts of chargers and wired headphones, which can reduce the cost. But in the end, the BOM is still increased, which shows that the iPhone 12 is still facing the risk of price increase. < / P > < p > as for the cost increase, 5g network is naturally included. IPhone 12 is Apple’s first 5g mobile phone, which adopts the solution of external high pass snapdragon 5g modem to realize SA / NSA dual-mode networking. In addition, the iPhone 12 series is also upgraded to OLED screen, and the rear lens is upgraded from 6p lens to 7p lens, and the charging power is upgraded to 20W. In other aspects, Guo predicted that the iPhone 12 would not support a high refresh rate, mainly due to high power consumption, smaller battery capacity and 5g network support. If you add a high refresh rate, it will significantly reduce the use experience. In addition, Guo said the iPhone 12 series could be shipped as soon as early October.
