Talking about mobile phones, I believe that many readers in front of the screen definitely know more about the use of mobile phones than Xiaobian. However, I don’t know if you use the mobile phone in the following days, but some methods are wrong. Behavior, let us take a look at it!
[New mobile phone battery must be completely used up to charge]
After many people buy a new mobile phone in the store, many people usually charge the mobile phone after the battery is fully exhausted, thinking that the battery of the mobile phone is good.
But in fact, this is a wrong approach, because now our mobile phone basically has the material of the battery is lithium, overcharge and over discharge will cause great damage to this type of battery.
[Mobile phone screen is fragile to film]
When the mobile phone is bought, usually the manufacturer will affix a original film. This operation is often done under vacuum conditions, so there will be no small bubbles that we usually see. The reason why manufacturers do this is to protect the tempered glass of the mobile phone screen for a longer period of time. The hardness of this layer of tempered glass can reach 6.5, which is higher than the hardness of ordinary metals. If you are a mobile phone, you can choose a film, because it can make the screen of the phone less scratched and use longer. After all, cell phone films are cheaper than screen films.
[Use of mobile phones for a long time can cause cancer in people]
This topic has always been very concerned by everyone, especially the older people, who are not able to understand the practice of holding their mobile phones when they see their children sleeping, they often whisper in their ears. Take a little farther.
In fact, as long as the mobile phone passes the national 3C certification, even if it is used for a long time, the electromagnetic wave is within the safe range.
If you are a person who cares for your body, you should pay more attention to controlling the time of using your mobile phone. When you are resting at night, try to keep your mobile phone away from yourself.
[Mobile phone will cause degaussing of bank cards, ID cards, etc.]
Bank cards and ID cards can be said to be essential items in our lives, one for storing money and one for authentication. If these two things go wrong, it will be very troublesome to solve them.
Because the current ID card uses IC smart cards, the information is stored in the chip. The electromagnetic field generated by the electromagnetic wave emitted by the mobile phone does not cause the bank card and ID card to degauss. It is purely rumor.
