What is the reason for the bad signal of iPhone 12 series?

The strength of the cell phone signals is crucial for users. Poor cell phone signal may cause you to play games, because of high network latency and frequent dropouts; when using the mobile browser to view the web, users also need to wait for a long time; open Facebook to reply to other people’s messages, you will be prompted to send failure.

Apple iPhones have been trolled for bad signals, and in 2016, Apple officially released the new iPhone 7 series, which is when Apple introduced the Intel baseband. At the time, many users said that the iPhone 7 signal was poor, and people pointed the finger at Intel baseband.

Despite the fact that the iPhone 12 series comes standard with Qualcomm baseband and 5G support, which theoretically improves signal performance, some consumers still report that the iPhone 12 series signal in their hands still does not perform as well as they would like.

So it seems that the poor iPhone signal and baseband does not have much to do with it. So what are the factors that affect the iPhone signal?

What is the reason for the bad signal of iPhone 12 series?

To judge the good or bad signal of the cell phone, not only look at the baseband. In fact, there are many factors that affect the signal, mainly divided into the following areas:

  • environmental factors. If you encounter rainy weather, the signal penetration will become weaker because the density of water in the air becomes greater, so the cell phone signal will become worse.
  • Building and crowd density. The signal is propagated in a straight line, when you are indoors, in underground parking lots, and places with more tall buildings, the signal will encounter more obstacles, and eventually the less signal the phone can receive. If you are in a crowded place, there may be signal congestion because everyone is using the same signal band in the same place.
  • Signal blind areas. In remote areas, such as rural areas, mountains, or woods, because the operator did not build communication facilities in these areas, or the base station signal range did not cover, so the cell phone signal will become poor, or even no service.
  • electromagnetic interference. The cell phone signal is transmitted through electromagnetic waves, like signal blockers, fake base stations, black radio, etc., which will cause interference to the cell phone signal.
  • SIM card wear and tear. Frequent plugging and unplugging of SIM cards will cause wear and tear on them, and the phone signal will naturally become weaker, or even unrecognizable to read.

In addition to the above external factors, the system bugs, software optimization, body antenna design, internal space structure, etc., will also have an impact on the phone signal.

In other words, the cause of the iPhone signal is the phone itself.
