Mobile phones are our important communication tools. If your mobile phone always has a bad signal, that ’s really anxious. You ca n’t hear the phone and you ca n’t connect to the Internet. Sister R has this experience. Several people are together. Someone just has no signal on the mobile phone, and someone’s signal is particularly good.

What does this mobile phone signal have to do with it? Some people think that it is related to the mobile phone itself. Some brands have a good signal, while others have a poor signal. Recently, there is a saying on the Internet that mobile phone signals are also related to mobile phone cases. Is this true?

Does the mobile phone case really affect the signal? According to Rui Wu’s test, in a poor signal environment, the metal phone case has an influence on the mobile phone signal!

We can see that after the iPhone 4 signal is stable, the mobile phone is displayed with only three grid signals. After the metal phone case is put on, the signal immediately becomes a grid. After taking off the phone case, the signal returned to three divisions.

This is not the case with iPhone 4, iPhone 6 plus, and Redmi Note phones, but this experiment was performed in a poor signal environment. Does the phone case affect the signal in daily life? Come and listen to what everyone says.

Sister R interviewed a colleague at random: “Do you use a mobile phone case? Will the signal become worse when a mobile phone case is installed?” The colleague replied: “There is no obvious effect, but it seems to say that the metal case has some effect.”

The metal case does have an impact on cell phone signals.

The phenomenon of shielding effect of metal on electromagnetic waves is very common. Some people encounter it almost every day, and related experiments are very easy to do. Entering the elevator, the mobile phone immediately loses the signal. This is the “metal cover” shielding the mobile phone signal; putting the mobile phone in the microwave oven to close the door, wifi immediately disconnected, etc. These phenomena tell us that metal has a strong shielding effect on electromagnetic waves.

Although the metal mobile phone case is not an elevator or a microwave oven, its impact on mobile phone signals is also great. The reason is easy to understand, and everyone understands it. However, many people, because of busy work, have no time to think. As a result, after buying a metal mobile phone case, they soon found that the mobile phone signal became very poor. Therefore, some users went to the mobile operator to change the sim card. I went to the repair shop to overhaul the mobile phone.

Other users, because the home is near the base station, the signal has been very good, so that after installing the metal case of the mobile phone, the mobile phone signal was not found to be very strong, so this problem was ignored. When you leave home and are far away from the mobile phone base station, you find that the mobile phone signal is getting worse. The first time you think of it is not the metal phone case, but the blame for the poor surrounding signal.

Some people at home and abroad have conducted such an experiment. The signal was originally full, and when the metal case was put on, the signal immediately dropped by one or two. If there were only two grid signals, the phone could not be connected immediately after you brought the metal phone case. You can search and watch such videos by yourself, so I won’t go into details here.

How to solve?

1. Use TPU soft cover — environmentally friendly raw material, light and soft. Using high-quality TPU pure color ultra-thin silicone sleeve tested by SGS, the feel is delicate and smooth. Super flexible, wear-resistant and anti-oxidation, environmental protection without odor, it will not change color and brittleness for a long time. More importantly, do not block the signal of the cell phone!

2. Select a half-pack mobile phone case — high-end PC with advanced technology, Seiko to achieve a beautiful half-bag appearance, shiny gloss, put it down, focus on details, precision production, the pursuit of fashion exquisite and comfortable feel, give the mobile phone the signal!

3. If you really like metal phones, you may wish to pay attention to the “Ruiwu Liujin Series” mobile phone case. It also feels like heavy metal, showing a good metallic effect. It selects “the internationally leading electroplating process” and has zero damage to mobile phone signals.
