Fast science and technology November 21 news, the topic-ldquo;iPhone signal disease is difficult to treat & rdquo; on the Baidu hot search list, attracting netizens' attention.

Public reports show that iPhone signal problems have existed for a long time.Back in the Jobs era, iPhone 4 was exposed because of antenna design problems & ldquo; 's death grip & rdquo;.

Apple advises users not to hold the lower left corner of the phone with their hands, because there is an antenna in the lower left corner of the iPhone 4. The contact between the human body and the antenna of the frame will cause undesigned interference to the reception and transmission of electromagnetic waves.

Enter the 5G eraThe iPhone signal problem is still not improved.

Previous bloggers have tested the signal strength of Glory Magic5 Pro, OPPO Find X6 Pro, Meizu 20 PRO, Huawei P60 Pro and iPhone 14 Pro Max.

A total of three channels are tested in this test, which are LTE FDD Band3 1900, LTE FDD Band3 1575 and LTE FDD Band3 1250. The test results show thatIPhone 14 Pro Max is at the bottom.

IPhone 14 Pro Max is at the bottom.

It is worth noting that in recent years, Apple has tried to solve the signal problem by developing its own 5G baseband, but according to analysts, the use of the self-developed 5G baseband will be by the end of 2025 at the earliest.

The source said that a baseband version being developed by Apple does not support faster millimeter waves, and that the Intel code used by Apple has encountered problems and needs to be rewritten, and the prototype tested has overheated.

It is widely believed that Apple's self-developed 5G modem, on the one hand, is to get rid of its dependence on Qualcomm as soon as possible, and on the other hand, it can solve signal problems and increase profit margins, but for now, this problem will not be solved in a short time.
