The iPhone 12 series was officially launched. On the opening day, there were a lot of people outside Apple's offline stores. In addition to the users who had ordered the new machine earlier to get the new machine, more consumers wanted to experience the 5g version of the iPhone 12 Series in the store.
Although the new machine has been on sale for several days, the heat of iPhone 12 series is still undiminished. Besides charging and endurance, the iPhone signal problem has been make complaints about the Internet users.
As for the signal, it's really a bitter tear for the majority of iPhones, especially in the subway, parking lot, elevator, and sometimes even in the shopping mall, your iPhone signal is constantly dropping. Downloading a picture can buffer half a day, which makes people wonder whether it's the operator's problem or the mobile phone's problem.
The good news is that Apple's 5g mobile phone has not arrived until many generations have been updated. As Apple's first 5g mobile phone, some users think it will be better than the 4G iPhone in terms of signal at least
Here's to learn about it. This year's iPhone 12 uses A14 bionic chip, which is the world's first 5nm smart phone chip. The A14 bionic chip uses TSMC's new 5-nanometer process technology, which means that it is more efficient than the previous 7-nanometer processor, which improves performance and reduces power consumption. Most importantly, the A14 bionic chip is ahead of any processor technology currently available on Android devices, including Intel chips, whose latest 11th generation core processor uses a 10 nanometer process.
After getting a general idea of the A14 bionic chip, we're going to actually experience how the iPhone 12 Pro signals. In order to let everyone feel the signal strength more intuitively, we use the identity of an ordinary user to test, so we do not use professional instruments, but use a 4G card and a 5g card to compare the signal strength of iPhone 12 pro and iPhone 11 Pro max.
There are still many choices about the selection of iPhone 12 in the cellular network column, including dealing with 4G to 5g switching and 5g band dropping to 4G and other conventional operations (there are three options for data selection: enable 5g, auto 5g and 4G respectively; At the same time, the optional data modes in 5g mode include: more data, standard and low data mode are allowed to be used in 5g mode), and intelligent switching 5g Technology (Apple measures various software and optimizes it. When users do not use 5g, the system will put the network in LTE to save power).
In the actual test, in order to test whether the signal is improved or not, the 4G mode test is selected first. IPhone 11 Pro Max and iPhone 12 Pro were used in elevator, underground parking lot, outdoor, subway station and car.

It should be noted that the iPhone 12 series seamlessly supports SA / NSA dual-mode 5g experience and supports up to 17 5gnr bands at the same time.
From the comparison of these groups, we can see that the signal strength of iPhone 12 pro in 4G mode is better than that of iPhone 11 Pro Max under 4G network. The download rate per second of iPhone 12 Pro can be faster. However, this difference is not obvious in actual use. Moreover, in some scenarios, there will be anti overtaking of iPhone 11 Pro max.
Network speed also has a lot to do with 5g signal strength. The next step is to test the 5g speed, because the iPhone 11 Pro Max does not support 5g, so there is nothing to compare.
We tested the 5g speed of the iPhone 12 pro, indoor, outdoor, elevator, parking lot and subway car.
IPhone 12 Pro 5g speed indoor test
In the indoor environment, iPhone 12 Pro can search 5g signal, and the download rate is 408.7mbps and the upload rate is 48.9mbps.
IPhone 12 Pro 5g speed outdoor test
But when it comes to the outdoors, the download rate of the iPhone 12 Pro has dropped to 313.7mbps and the upload rate is 28.9mbps.

IPhone 12 Pro 5g speed underground parking lot test
In areas with poor signals such as elevators and parking lots, the 5g signal of iPhone 12 Pro will change to 4G. Although the upload and download rates have decreased, it does not affect the use of the iPhone 12 pro. It can be used either by calling or surfing the Internet.
IPhone 12 Pro 5g speed in car test
Unexpectedly, data from the subway car were detected. Many users did not have signals in the subway, especially the iPhone users make complaints about the subway. In order to ensure that the difference between the data is not big, Xiaobian has carried out tests between two subway stations, and the difference of the test data is not big. According to the data tested at present, the signal of iPhone 12 Pro has improved. In the places where 4G mobile phone was not connected before, the iPhone 12 Pro has network, and can receive wechat information at least.
In addition to supporting 5g, the signal performance of the new iPhone 12 series is indeed greatly improved compared with that of the previous generation. In addition to the baseband upgrade, Apple's antenna system for the iPhone 12 series is also comprehensively optimized at the design level to maximize the signal performance.
Compared with the iPhone 11 series, the poor signal performance of the iPhone 11 series under special circumstances really makes many users miserable. This 5g support and antenna system optimization let everyone get rid of the anxiety about the poor signal for many years.
