The test site is in the United States. Although the speed of the iPhone 12 is 2.3 times that of the 4G iPhone after it supports 5g, which is the most obvious improvement, compared with many 5g mobile phones under LG, Samsung, one plus and Google, it is completely inferior.
Among the top 25 mobile phones with 5g network download speed, apple even failed to be shortlisted. The first one is Samsung Galaxy S21 5g, which can reach 56mbps. IPhone 12 Pro is 36.9mbps, pro Max is 36.2mbps, 12 is 29.6mbps, 12 Mini is 32.9mbps.
Although the X60 baseband of snapdragon 888 on S21 is indeed more advanced than the x55 of iPhone 12, professionals tend to think that the transceiver design such as RF antenna is the reason for the slow network speed of iPhone 12. After all, Samsung is already the third generation of 5g mobile phones, and apple is still the first generation.
Moreover, even for s215g, the peak download speed of 2.5Gbps of x55 baseband, let alone 7.5gbps of X60, can not be detected. There is also a significant difference in Internet speed among the four models of iPhone 12.
