Why does the phone heat up as soon as it is charged, and why does the phone heat up when charging

Reasons for battery heating: The power consumption of the mobile phone in standby is very small, that is to say, the equivalent load resistance of its battery is large, so the discharge current is very small, so the battery will not heat up, and the internal consumption of battery power is very small. The power consumption of the mobile phone when it is ready to talk or use *** is very large, that is to say, the equivalent load resistance of its battery is small, and it is discharged with a high current when working.

After the battery discharges a part of the electricity, the internal resistance increases, but the current required for the work of the mobile phone cannot be reduced, so a considerable part of the energy is consumed on the internal resistance of the battery, resulting in the battery heating, the discharge acceleration, and the battery use time is quickly shortened. Hazards of mobile phone battery heating: 1

The battery of the mobile phone will heat up for a long time, which will cause the internal parts of the mobile phone to heat up, so that the mobile phone will restart or hang up the call** 2If the mobile phone battery is heated for a long time, the heat of the battery itself will increase, if it is sealed (nokia and the like are not sealed, the battery is directly loaded into) the battery will make its internal air expand violently, resulting in the battery like an external protrusion, which will seriously make the battery**. 3.

Prolonged heating of the mobile phone battery will accelerate the aging process of the mobile phone itself and shorten its lifespan. Causes, hazards, prevention and solutions of mobile phone battery heating 2 Prevention and solutions of mobile phone battery heating: 1.

Prevention methods: 1It is normal for the phone to generate no more than 60 at normal room temperature, and the battery will not be damaged.

2.It is not advisable to use a high-current charger for too long, as charging for too long will damage the battery and generate heat. 3.

It is best to use the charger in an original or quality reputable product. 4.If you are not in a hurry to use it, it is recommended to charge it with a base charger (slow charging mode) to avoid heating the battery.

5.If you feel that the phone is a little hot when using the phone to listen to *** or battery charging, if it exceeds 60, immediately return to the standby state or change the battery, and unplug the charger immediately if it is charging. Two.

Solution: 1If the mobile phone battery has been charged and bulging, there is also a way to solve it.

It is to use your fingers to find the gap of the battery first (the back of the mobile phone battery is close to the charging electrode of the mobile phone, and it is a little soft when pressed), and poke a small hole with the target to let the air inside run out. 2.Throw away another battery to buy.

It's normal to kiss this. Today's e-commerce businesses are trying to shorten the charging time. Just adjust the current and voltage a little more.

The charge is on, but the battery temperature is high. It has a great impact on the life of the battery. I advise you not to play while charging.

Either that, it just shuts down. Let's go down, dear.

If the lukewarm is normal, it will be even higher if charging while playing.

Because the mobile phone battery receives the shock of electric current.

Don't play while charging, it's easy to heat up**.

Perhaps most people have such an experience, the mobile phone will get hot after a long time, so if the mobile phone is very hot and the mobile phone is out of power, can it be charged directly? The answer is no! Let's explain in detail why?

1. Today's mobile phones use lithium batteries, which have high requirements for temperature, and overcooling or overheating will affect the life of the mobile phone battery. So you've heard that your phone freezes off in winter.

In the same way, the mobile phone is very hot, and the mobile phone battery is already in a high temperature environment, and it is very dangerous to charge the mobile phone at this temperature. If it is light, it will damage the battery life, resulting in a shorter battery life of the mobile phone; If it's heavy, it's booming!

2, as we all know, there are many headlines such as "Is it okay to charge while playing with your phone", but in fact, these are completely okay. The reason for those who say no, is nothing more than that: charging the phone while playing with the phone will heat up badly, and then it will blow up!

So, it's okay to charge your phone while playing, but be sure to pay attention to heat dissipation, and remember to remember.

3. What should I pay attention to?

a. Pay attention to heat dissipation during charging, especially at night, don't put your phone next to the pillow to charge, what if it slips under the pillow? The charging heat is not very serious, but it has not been able to dissipate heat, and the temperature will still rise. It can be placed on a bedside table, or on a wall phone holder, like this.

b. Don't charge your phone in an overheated or cold environment, it's dangerous.

c. When the mobile phone is hot, turn off the screen of the mobile phone, let it dissipate the heat, and then charge the mobile phone.

There is an energy conversion process during the charging of vivo mobile phones, during which a certain amount of heat will be generated, and the charging power of flash charging and ultra-fast flash charging models is larger, and the heat generation will be higher while shortening the charging time, which is a common heating phenomenon.

The following methods are recommended to reduce fever:

1. Use a matching charger and data cable to charge, which can not only ensure the stable charging speed, but also ensure the safety of use;

2. Try to avoid using the mobile phone when charging, the use of the mobile phone during charging will increase the operating power consumption of the mobile phone, resulting in an increase in heat;

3. When the temperature of the mobile phone is high, the protective case can be temporarily removed;

4. When charging, place the mobile phone on an object with good heat dissipation (such as a desktop) and avoid placing it on an object that is not easy to dissipate heat (such as a sofa, quilt, blanket);

5. Before charging, one key to speed up the cleaning of background programs to reduce the power consumption of the mobile phone.

Normally, when charging the mobile phone battery, a chemical reaction occurs in it, which is an exothermic reaction, so it will heat up, and the metal will also heat up when it is energized, which causes the phone to heat up when charging.

Under normal circumstances, there is only a small slight heat when the phone is charging, if the heat is serious, it means that there are too many background programs on the phone, so it is good to clean it up. If it still doesn't work, you should consider whether the motherboard is broken.

When you charge the No. 5 battery, it will also heat up, and charging is a process of chemical reaction inside the battery. Of course, the quality of some domestic copycat machines is only replaced by batteries**, which is actually caused by internal chemical reactions.

When the mobile phone is charging, the voltage is higher than the standby voltage, and it will naturally heat up, if you charge at the same time in the operation of receiving and playing games, etc., the mobile phone is more likely to heat up, so it is recommended not to operate the mobile phone when charging, and the voltage will exceed the usual many times at the moment of calling or connecting to the network, which is easy to damage the sensitive and complicated parts inside the mobile phone, resulting in frequent maintenance of the mobile phone. Secondly, the radiation during charging is also dozens of times that of usual, which will cause damage to the human body. Since the battery life is calculated according to the charge and discharge cycle, the number of charges directly affects the battery life of the mobile phone.

If the power supply is repeatedly plugged and unplugged, the battery life will be reduced due to repeated discharge. Therefore, when the mobile phone is charged in the power-on state, it is best not to do operations such as playing games, and it is best to turn off and charge. In addition, it is safer to charge with the original charger, so that the battery life of the phone will be longer.

Some mobile phones do not support charging while playing, which will cause the mobile phone to charge hot, followed by the rubber grinding is the unstable current of the charging caused the mobile phone to heat hot, and it may be that there is a problem with the charging plug or charging cable, it is recommended to check whether the charging cable is in poor contact or damaged, if the beam bucket is damaged, it needs to be replaced in time. Finally, the battery of the mobile phone has a lifespan and needs to be replaced after a long period of use.

Because the battery generates heat when it is working, it can be divided into Joule heating, polarization internal resistance heat, chemical reaction heat and so on according to the different principles of heat generation. The largest proportion of this is Joule fever. In the charging process of the battery, the method of "constant current and constant voltage" is generally adopted, so that there is an electric current inside the battery.

Such an electric current passes through the resistance inside the battery, which naturally generates a certain amount of heat.

Other reasons why the phone is heating while charging:

1. The phone is still in use when it is charging.

2. The original charger is not used when charging the mobile phone.

3. Charge the phone with the phone case.

There is an energy conversion process in mobile phone charging, during which a certain amount of heat will be generated, the charging power of the flash charging model is larger, and the heat generation will be higher while shortening the charging time, if the surrounding environment temperature is high, such as summer, it is not conducive to the heat dissipation of the mobile phone, and the heat during charging will be more obvious. It is recommended to refer to the following methods:

1. The standard charger has been rigorously tested, and the standard charger and data cable are used for charging, which can not only ensure the stable charging speed, but also ensure the safety of use;

2. The use of the mobile phone during charging will increase the operating power consumption of the mobile phone, resulting in an increase in heat, so the use of the mobile phone should be avoided as much as possible;

3. If you are wearing a protective case for your mobile phone, removing the protective case can effectively improve the heat dissipation of your mobile phone, but you should pay attention to the heat sensation of your hands will be more obvious if you directly contact the heating part of the mobile phone within a short period of time after removing the protective case.

4. Place the mobile phone on an object with good heat dissipation (such as a desktop) for charging, and avoid placing it on an object that is not easy to dissipate heat (such as a sofa, quilt, blanket);

5. Before charging, one key to speed up the cleaning of background programs to reduce the power consumption of the mobile phone.

Causes of heating while charging your phone:

At present, most smartphones use the charging method of linear trembling charging. The power adapter is usually 5 volts output, while the mobile phone power supply is between 3 and 4 volts, the larger the voltage difference between the battery voltage and the output voltage, the higher the loss rate of electric energy, and the heat generated by the power loss will all be scattered on the mobile phone, which will cause the mobile phone to heat up when charging.

Solution: 1. When charging, take off the protective case of the mobile phone, and the mobile phone case will seriously affect the heat dissipation of the mobile phone when charging.

2. Don't play with the slag destroyer while charging, because the mobile processor of the mobile phone is also a big source of heat.

3. It is best to use the original charger.

4. Clean it up.
