Apple 13 6 1 bad signal

The poor signal of the Apple 13 is a problem with the phone, mainly due to the problem of the antenna.

Antenna design, in the iPhone 13 signal test, the iPhone's overly compact internal design makes it impossible to leave enough space for the signal antenna inside the iPhone, resulting in a significant reduction in the efficiency and area of the antenna to receive signals.

To put it simply, if you want to boost your iPhone's signal, the only way is to overhaul the iPhone's internal structure and find a way to make more room for the antenna system. However, today's iPhone 13 is equipped with more advanced hardware such as high brush screen, which further squeezes the internal space, resulting in the signal performance of the iPhone 13 is even worse than that of the iPhone 12.

Moreover, if it weren't for Apple's optimization of the Snapdragon X60 baseband, the performance might be worse than it is now, although many netizens blamed the poor signal on the antenna material used in the iPhone. However, according to what we know, the replacement of antenna materials should not have a big impact on signal strength.

Apple just replaced some of the raw materials in the original industrial liquid crystal polymer material with ** reused plastic, and the antenna material used is actually no different from the previous generation. Moreover, industrial liquid crystal polymer (LCP) is also the material used in the vast majority of 5G mobile phone antenna belts, and there is certainly no problem in terms of performance.

It can be seen that the signal problems faced by the recent generations of iPhones are largely due to the unreasonable design of the antenna system, which has little to do with the baseband and antenna materials. So why hasn't Apple set out to address this issue? Quite simply, because it can't be done, unless Apple is willing to abandon the current design scheme and overhaul the structure of the iPhone.

The iPhone's overly compact internal design makes it impossible to leave enough space for the signal antenna inside the iPhone, resulting in a significant reduction in the efficiency and area of the antenna to receive signals.

In single-SIM mode, although the signal quality of iPhone13 is not particularly strong, it is also at a medium level, and there is no pressure to play ** and surf the Internet, and there will be no malfunction.

However, in dual SIM mode, there will always be one card of the iPhone 13 that drops the chain, and the signal of the other card may be full, but there is no guarantee that both cards have high signal quality. As a simple example, if the iPhone 13 inserts a mobile card and a Unicom card at the same time, then it is very likely that the signal of the mobile card is full, while the signal of the Unicom card is very poor.

However, when the mobile card is removed, the signal of the Unicom card will return to the normal level, and the two cards cannot work at the same time. This may be the main reason for the poor signal of iPhone13, now there are more and more users who have two cards, and Apple's handling of dual SIM dual standby is not rigorous, so users mistakenly think that the signal of iPhone13 is too poor.

A bad cell phone signal can be due to the following:

1. The mobile phone is in the signal blind zone, which will cause the phenomenon of "not in the service area", "temporarily unreachable" or call interruption, which includes outside the network coverage area.

2. It is a bad signal caused by interference.

3. Disconnection caused by the failure of cross-zone switching.

4. Due to the temporary failure of the network, or the network is particularly busy, it will also cause the mobile phone signal to be poor.

5. The mobile phone card using the 2G network will also cause bad signal and other reasons.

1. After unlocking the iPhone first, open the phone [Settings], as shown in the figure below.

2. Then in the settings page that opens, click [General], as shown in the spine of the figure below. Volt type.

3. Then in the general page that opens, click [Restore], as shown in the figure below.

4. Then in the page that opens, select [Reset Network Settings, as shown in the figure below, and the signal will be improved.

Here's how to solve the poor signal of Apple 13:Tools Raw materials: iphone13, .

Method Steps:

1. Click General to restore the best signal by resetting the network, click General in the settings.

2. Click on the transfer or restore iPhone to slide the general interface, and click the transfer or restore iPhone option at the bottom of the interface.

3. Click Reset Network Settings to solve the problem.

Some of the reasons for the poor signal of the Apple 13 are as follows:1. Operators.

Different operators, in fact, the difference in mobile phone signal is quite large. If your mobile phone signal is not very good, you can try to change to another carrier.

2. Region.

If you are in a remote mountain village, the signal may not be fully covered, so the signal will be poor.

3. The floor is low.

In the city, there are too many high-rise buildings, such as if Jianguo lives on a low floor, it is easy to block the signal, which will also lead to poor mobile phone signal.
