buy their mobile phones and like to match them with various spare parts. As everyone knows, you think this is good for mobile phones. In fact, it is not only harmful to mobile phones, but also harmful to ourselves.
Small mobile phone fan
Small mobile phone fan is so small that it can't blow much wind at all, and it also has great damage to the battery of the mobile phone.
First of all, except for certain mobile phones with power banks, that is, those that support reverse charging, most mobile phones only support the current supply of their own internal components.
Although the small fan is very small, it takes a long time to supply current. If it takes a long time, it will cause irreversible damage to the battery and motherboard of the mobile phone. Even if the battery is damaged, the key is the motherboard. Once the motherboard is damaged, it will cost a lot of money to repair it.
So, if you want to use this small fan, plug it into the power bank.
Anti-spy phone film
To prevent others from snooping on your phone, it’s very simple. Just keep an eye on it. In other words, when you’re playing with your phone, look both ways. Whoever intends to look at your mobile phone, "greet" their relatives!
The technical realization principle of the privacy film is actually to reduce the transparency of the mobile phone. We know that the brighter the mobile phone screen, the more visible The wider the angle.
The privacy film is to reduce the brightness, for people who want to peek at your phone, it can indeed prevent it, but for yourself, the brightness is reduced, you have to increase the brightness, and you have to be at a certain angle to see the phone The text on the phone, the phone is long, it is also harmful to my eyes.
also has a matte film, which is even more harmful to the eyes and greatly weakens the display effect of the screen.
Hard plastic protective case
Hard plastic protective case for mobile phones, basically zero protection for mobile phones.I once bought a good-looking plastic protective case. Once I accidentally dropped the mobile phone on the ground, the shielding cover on the main board of the mobile phone broke directly.
The protective case of the mobile phone is to buffer the mobile phone when the mobile phone is dropped to the ground. The plastic hard shell is a kind of impact kinetic energy, without weakening, directly transmitted to the mobile phone body.
protect the phone?
Protect yourself from loneliness!
Mobile phone dust plug
Mobile phone dust plug is a spare part. I don’t think there are a few people who buy them specifically. They are usually given by the seller randomly when you buy tempered film or protective shell yours.
What you have to do is: pick out and throw it directly into the trash can!
Unless you live in a desert area and often get sand in your mouth while wearing a mask, then you need to.
In other environments, completely unnecessary!
This thing not only affects the heat dissipation of your phone, but also damages the phone interface.
lens tempered film
mobile phone lens protective film is a proper IQ tax!
Although the lens and screen are both glass, the thickness and hardness of the glass of a mobile phone lens is comparable to that of a non-mobile phone screen. Many mobile phone manufacturers choose sapphire glass to prevent scratches. The hardness of sapphire glass can hardly be destroyed by sand.
The lens film has no purpose except to make your phone camera unclear.
