Man is really a magical species, and the more familiar he is, the easier it is to fall into a cognitive black hole.
According to statistics, more than half of the people spend at least 5 hours a day on their mobile phones, eating, shopping, going to the toilet... Except for sleeping, the phone has never left its hands.
Although the mobile phone is regarded as a sibling, there are few people who can answer all the following mobile phone skills correctly.
unbelief? Let's take a look
First, the mobile phone is placed on the desktop, and the screen is facing inward or facing outward?
Solution: The screen is facing inward and facing the desktop.
Is the answer in your mind this, why is the screen facing inward?
The first is that it is not easy to be dirty by dust, and it is safer to be splashed by soup water;
Secondly, most of the current mobile phone cameras are raised, the screen is placed outward on the table, the camera will directly contact the desktop, easy to scratch, affecting the shooting effect;
Finally, there is the privacy problem, the screen is up, if there is a message or a phone call, it is easy to be seen by people passing by, in addition, various information push is also easy to interfere with their attention.
Second, the mobile phone in the pocket, the charging port facing up or facing down?
Solution: The charging port of the mobile phone is placed in the pocket facing up.
There is generally a lot of dust or hair in the pockets of clothes and pants that cannot be washed off.
If the charging port is facing down, when the mobile phone is rubbed in the pocket, the dust hairs are easy to burrow into the charging port.
Over time, the charging port is easily blocked, resulting in poor charging contact.
Even more, if there is metal debris in the pocket, once it enters the charging port, it is easy to cause a short circuit of the mobile phone, which is a safety hazard.
Therefore, it is still necessary to make a dust plug, if there is no dust plug, then usually try to put the mobile phone charging port up in the pocket.
Third, charge the mobile phone, plug in the power supply first or plug the mobile phone first?
Positive solution: before charging, first plug in the power supply and then plug in the mobile phone; after charging, first unplug the mobile phone and then unplug the power.
This is mainly to avoid the harm caused by the phenomenon of power surges.
When we usually charge the mobile phone, we can occasionally hear the sound of current nuisance or see a small spark on the plug, which is the phenomenon of power surge, which is a temporary current and voltage fluctuation that appears in the circuit and lasts for about one millionth of a second.
Generally in the circuit connection of a moment of generation, so first plug in the power supply to let the surge pass, and then connect the mobile phone, is a relatively safe charging behavior, after charging, first unplug the mobile phone, let the mobile phone out of the matter, and then pull the charging head, then the surge can not hurt the mobile phone.
Surge damage should not be underestimated, light will reduce battery life, reduce equipment efficiency, heavy is easy to cause safety hazards.
Fourth, answer the phone for a long time, use the left ear or the right ear?
Solution: Left and right ears don't matter, rotation is the key.
There has been a fallacy circulating on the Internet that the left ear is safer, on the grounds that the right ear is closer to the right brain, and the right brain is more important, and mobile phone radiation will hurt the brain.
The left and right brains are definitely equally important drops, which side is a little missing, I am afraid that they can not live a normal life.
Although the radiation of mobile phones is within the controllable range, the radiation power will also be affected by the strength of the signal when making a call. Studies have shown that prolonged periods of continuous radiation may affect the head.
Therefore, if you have to call with your mobile phone for a long time, it is recommended to rotate the left and right ear calls every one or two minutes.
If it's too much effort to change hands, turn on hands-free or wear Bluetooth headsets.
With the development of Bluetooth technology, now Bluetooth headsets are not only more functional, the price is more and more close to the people, take the professor's recent experience of the GreenLink Bluetooth headset T3, the price of 100 yuan will do a very good job of sound quality, high and low frequencies are more balanced, sound very comfortable, but also with ANC active noise reduction function and AI call noise reduction, Bluetooth 5.2 chip, the connection is fast and stable, very suitable for college students or workplace white-collar workers as a daily basic model.
There are always more ways than problems, don't go through with your own brain.
