Have you noticed that the charging ports of previous functional machines are not fixed in one place, some are on the side and some are on the bottom?
But since the appearance of smart phones, the charging interface has always been at the bottom. Over time, everyone has become accustomed to the location of this charging interface, and they do not think there is any problem with the charging interface at the bottom.
Haven’t you wondered why the charging ports of smartphones are all at the bottom of the fuselage? There are four reasons.
First
The charging port facing down is not easy to get dust. This is quite understandable. Just like the smartphones in the early years, the 3.5mm headphone jack was still standard on the phone, but the headphone jack placed on the top of the phone was full of dust even if the headphones were often inserted, not to mention Users who don’t use headphones often.
The same is true for the charging port. With the increase of the use time of the mobile phone, the dust accumulated in the charging port will increase. Compared with the design of the charging port facing up or on the side, it has better concealment, and the amount of dust accumulation also increases. will be less.
If the charging port has accumulated dust for a long time and is not cleaned up, it will easily lead to poor contact of the interface for a long time, affecting the charging efficiency, and even damage the mobile phone in severe cases. What is even more terrible is that there are metal debris in the trouser pocket.
If it accidentally falls into the interface, it may cause a short circuit when charging the mobile phone, causing the mobile phone to burn out. So when the phone is put in the pocket, the charging port is best facing upwards.
second
It can better protect the data line. Similarly, students who have used functional phones should know that there will be many mobile phone charging ports on the side, so that the charging cable will be more easily folded to the data cable due to the direction.
For example, when charging with a power bank, the mobile phone is placed in the pocket. At this time, because it is the side charging interface, the data cable will be bent against the trousers pocket. In the long run, it is very likely that the data cable will not be in good contact or has been damaged. .
So sometimes you have to touch the data cable from time to time, so that the phone can continue to charge normally. Don’t ask me how I know it, everyone who has experienced it will understand it, just like using wired headphones before.
third
It is more convenient to answer the phone while charging. Although it is not advisable for everyone to answer or make calls while the mobile phone is charging, in fact, if the charging interface is at the bottom, there will be no trouble with the data cable going around your hands. If the interface is on the side or the top, it is difficult to say.
fourth
The charging interface is not set on the side or the top. In addition to the above situations, there is another because of the internal layout of today’s smartphones.
Nowadays, the internal layout of smartphones is basically the same. The handset, camera, chip and other hardware of the mobile phone are often in the upper part of the fuselage, and the battery is in the lower part. In such a “crowded” space, the charging interface is at the bottom of the phone. It’s the best home.
However, although the charging ports of smartphones are all at the bottom, there is still dust. If it is convenient, you can regularly clean the dust on the port. You can stick double-sided tape on the toothpick and stick it into the port and wipe it repeatedly. It doesn’t take much time.
In addition, some classmates asked whether the phone should face the screen up or the back when charging. In fact, it is not a big problem, but if the screen is facing down, it can better protect your privacy content, and you will not be seen by others when you come to the information. In addition, if the screen is usually facing down, it can also prevent the rear lens from being scratched.
Finally, I remind everyone that it is best to use the original data cable when charging. If there is no original data cable, it is best not to use a low-quality charger. Everyone understands the reason; also don’t wait until the phone is out of power before charging.
When the phone reminds you that there is still 20% of the power, go to charge it quickly, so that it will not hurt your battery so much.
Let’s take a look at the cold knowledge given by Bai.
