several generations of apple mobile phones before the 12th generation used the baseband of zettel. due to backward technology, the signal was extremely poor, and 5G only stayed on paper. until apple completely abandoned zettel and switched to Qualcomm's technology, it finally got the 5G product.
In recent years, Apple has always insisted on the rounded frame design, while the iPhone 12 series has returned to the tough style of the iPhone 5, and the edge of the middle frame is no longer radian, which is closer to a completely pure plane. Many netizens commented, "Apple is taking a retro route and regaining its tough style seven or eight years ago." In fact, this time it is not retro, but the introduction of new panel technology makes Apple feel that "there is no need to rely on curved surfaces to create a visual lightness".
compared with the previous generation, even though the whole iPhone 12 supports 5G, it is thinner. In terms of thickness, it has been reduced from 8.3 mm of iPhone 11 to 7.4 mm, which is basically equivalent to the second-generation iPhone SE. In terms of weight, the two Pro levels have not changed much, but the standard version is much lower (iPhone 11,194 grams; Iphone 12,162 grams). As for the 12 mini, it is only 133 grams, which can be described as extremely thin.
There is no doubt about the strength of Apple's A-series chips. This A14 Bionic chip still adopts a more advanced 5nm process, and its performance is by going up one flight of stairs.
due to the integration of 11.8 billion transistors, A14 not only has faster performance, but also has better power consumption control ability. According to official data, it is 4% higher than A12 chip, CPU(6-core design) and GPU(4-core design).
at the same time, A14 is equipped with a new 16-core Neural Engine, which doubles the number of cores and makes a breakthrough in machine learning performance.
