Why do young people like to play with mobile phones at night?

#growingknowledge together# Why do young people like to play with their mobile phones at night? Because the yin energy is strong, it can overcome the hot mobile phone. (Cold joke)

I don’t know if any of you have found out halfway through playing with your mobile phone that it is very hot. It felt like holding a time bomb and considering whether to throw it and explode it. In fact, the normal working temperature of the screen is -20~75°C, the normal working temperature of the CPU is -25~75°C, and the normal working temperature of the peripheral circuits of the mobile phone is -10~65°C. So everyone thinks that the phone is very hot, which is more than 40 degrees, which is within the normal range. (No need to throw away the phone)

Under normal circumstances, mobile phones are unlikely to explode. If the phone really explodes, it can only be caused by a short circuit somewhere or a bad battery. It is important to note that if the temperature of other parts of the phone is normal, but the battery temperature is so hot that it is difficult to hold it, then you should be careful.

But even if this kind of problem occurs, the scene is different from what everyone imagined. The design of current mobile phone batteries pays great attention to safety. When the battery is broken, there won't be that big of a noise. It's usually just a bulge in the battery. (It won’t have the same lethality, but don’t charge it, otherwise it will be another scenario)

If you notice something is wrong with your phone while charging, and the battery is bulging, you have enough time to give it a ride, but don’t Throwing objects out of the window is illegal.

In addition to being hot to the touch, the biggest disadvantage is that it can easily trap your teammates! Because mobile phones need space for heat dissipation, the built-in cooling will automatically reduce the processing speed and cause lag. Therefore, it is normal for everyone to find that the phone is hot and lags.

In addition, current mobile phone cases are usually very thick to prevent falling and do not dissipate heat. It is like wearing a sweater on a mobile phone in summer. If the phone gets hot, you can take off the mobile phone case first.

If your phone is extremely hot, you can do more than remove the phone case and wait for it to cool down. If you really can't wait to play, you can cool down physically. Method: Fold a paper towel into a square, add some water, and stick it on the back cover of the phone.

The best way to dissipate heat from a mobile phone is not to play with it, everyone knows this. There are also many mobile phones that generate heat and consume a lot of energy when the camera is turned on. Some people think that mobile phone cameras are coal-fired. Everyone usually remembers to turn off the camera after taking pictures.
