What s going on with the phone heating up while charging

The causes, hazards, prevention and solutions of mobile phone battery heating are phenomena that we can often encounter in the use of mobile phones. Basically, 90% of mobile phones will have a very hot battery after a long call, and even the phone will get hot.

Causes of 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.

Dangers of mobile phone battery heating:

1.Prolonged battery heating can cause the phone's internal parts to heat up, causing the phone to restart or hang up on a call.

2.If 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

Mobile phone battery heating prevention and solutions:

One. Prevention method:

1.It 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. Workaround:

1.If 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.

If it is the original mobile phone charger, it will generally not heat up, and the heating phenomenon is because the power output of the charger is too large or too small, but the heat will not affect your mobile phone....

Normal don't worry! Do not hit ** while charging.

This is normal It is recommended not to hit ** while charging

Anything is charged.

The Samsung phone battery has been activated at the factory and can be fully charged normally. The charging time is generally about 2-5 hours. Because the battery capacity and charger power of each mobile phone are not exactly the same, the charging time will also be different.

If you are using a 2A charger, the charging time is relatively short.

Charging copy power is large, conductive.

Causes the mobile phone to heat up the battery. Also, the CPU runs.

The high frequency of bai will also cause the battery and screen part of the mobile phone to heat up.

When the mobile phone feels hot while charging, take a small square towel, dip it in some alcohol, apply it to the hot area, and evenly apply it for a few minutes, the heat will be quickly dissipated, which is conducive to protecting the battery.

Of course, if there is no alcohol, you can also use water instead, but be careful not to dip it in too much water to prevent water from soaking into some crevices of the phone and damaging the components of the phone.

High power when charging, causing the phone battery to heat up.

In addition, the high frequency of the CPU will also cause the battery and screen of the mobile phone to heat up.

1. When the hand holding machine feels hot while charging, take a small square towel, dip it in alcohol, apply it to the hot position, and evenly apply it for a few minutes, the heat will be quickly dissipated, which is conducive to protecting the battery.

2. If there is no alcohol, it can also be replaced with water, but be careful not to dip it in too much water to prevent water from soaking into some gaps of the mobile phone and damaging the components of the mobile phone.

First of all, let's talk about what kind of machine you use! Then I can tell you clearly that today's miscellaneous smartphones have heating phenomena when they are charged for more than half a year! The biggest feature is the degradation of the circuit board and the battery.

Normally, if you play too much, you will get hot, plus it is hot in summer, and the heat is not easy to dissipate, so it will be naturally hot. If you find that your phone is unusually hot, then you should be vigilant, there is a possibility of ** at any time. Get your phone to the doctor right away.

Normal, because the battery has to convert electrical energy into chemical energy, which must produce heat energy.

It may be that it was too high to play before, and then it will heat up when it is charged again, don't worry, this is just normal.

Vivo mobile phones have an energy conversion process when charging BAI, and a certain amount of heat will be generated during this period, and the internal charging capacity of flash charging and ultra-fast flash chargers 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.

It's easy to understand.

When charging, there must be a circuit loop (understood as a transformer) to have a charging current to complete the charging, and a 220V AC power circuit.

One is the battery circuit.

One cannot be the other.

There must be resistance and current in the circuit, and of course it will heat up.

Moreover, both the charger and the battery will heat up.

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.

Some mobile phones do not support charging while playing, which will cause the mobile phone to charge hot, followed by the instability of the charging current that causes the mobile phone to heat up, and the other 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, and if it is damaged, it needs to be replaced in time.

During the charging process, the power circuit is working with resistance when it is running, and the resistance and current are playing with each other, and heating is inevitable, and it is mainly concentrated in the battery and PCB board.

Reminder: It is best not to use the mobile phone to play, play games, and watch ** when charging, which will lead to unstable voltage and generate more heat, and will also consume the life of the battery in the long run, and in some states this behavior will also increase the probability of the battery.

The processor is a highly integrated SoC chip, which not only integrates the CPU ** processing chip and the GPU graphics processing chip, but also a series of key chip modules such as Bluetooth, GPS, and radio frequency, which will emit a lot of heat when these chips and modules are operating at high speed.

If there is a problem with the battery, it is recommended to replace the battery, and if you have enough funds, you can directly replace the phone.

It may be due to the heat generated by using the phone while charging.

There is an energy conversion process in mobile phone charging, during which a certain amount of heat will be generated, and the charging power of the flash charging model is larger, and the heat will be higher while shortening the charging time, which is a common heating phenomenon.

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

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.

It is normal for mobile phones to heat up when charging, and there is constantly current in and out during charging, which will generate heat and cause heating; And when running the program, the internal hardware will also dissipate heat, causing the phone to get hot, closing unnecessary applications and reducing the burden on the phone.

There is an energy conversion process in device charging, during which a certain amount of heat will be generated, and the flash charging model has a larger power, and the heat generation will be higher while shortening the charging time, which is a common heating phenomenon. If the ambient temperature is high, such as summer, which is not conducive to the heat dissipation of the device, the heat during charging will be more obvious.

If you are using a vivo mobile phone, there are a few suggestions that can effectively improve the phenomenon of charging and heating:

1. Use the standard charger and data cable for charging, due to the different specifications and charging protocols of the third-party charger, it may bring heating and other problems to the device. Please use the standard charger and data cable to ensure stable charging speed and safe use.

2. Place the device on an object with good heat dissipation (such as a tabletop) and avoid placing it on an object that is not easy to dissipate heat (such as a sofa, quilt, blanket).

3. The device itself will heat up when charging, and the device will also heat up when using it, and the heat will be aggravated when the device is used while charging.

4. If you wear a protective case, removing the protective case can effectively improve heat dissipation, but it should be noted that within a short period of time when removing the protective case, because it is directly in contact with the hot part of the device, the heat sensation in your hands will be more obvious, and the heat sensation will be relieved after a little waiting.

5. Before charging, clean up unnecessary background applications to reduce the power consumption of the device and reduce heating.

There are five main reasons why your phone is hot when charging:

1.When the phone is charging, the temperature of the phone will rise rapidly, and during the charging process, the electrical energy is converted into chemical energy, during which energy is lost, and this energy is released in the form of internal energy, thereby accelerating the heating up.

2.You may not know that there are many high-energy-consuming apps in your phone, such as mobile games, **, etc., these apps will occupy a lot of memory when running, and the CPU will be overloaded, which will cause the phone to heat up.

3.Multiple apps run at the same time, this is the same as the above, although a single app may not consume much energy, but you may have problems if you open more than one, after all, everyone understands the principle of gathering sand into a tower and gathering armpits into a fur.

4.The mobile phone runs for a long time, although the mobile phone is not a human (but he is also a mobile phone), but it also needs to rest occasionally, if you play with it for a long time, touch it all the time, and it is strange that it does not heat up.

5.The problem of mobile phone case, in order to look good at the mobile phone, and at the same time in order to protect the mobile phone, we will choose some seemingly beautiful mobile phone cases for the mobile phone, who knows that the mobile phone case has a certain impact on the heat dissipation of the mobile phone, especially in the hot summer, while charging and playing with the mobile phone, in this case, the mobile phone battery will perform two operations - charging and discharging, the activity of the current in this process is very large, so it will cause the battery and charger to operate under heavy load and thus emit a lot of heat.

Because the battery will produce slow heat generation 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.

This electricity flows 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. When charging the mobile phone, the lead is not the original charger.

3. Charge the phone with the phone case.

Don't play with your phone while it's charging. Playing with the phone while the phone is charging will cause the phone charger to overheat, because it will work for a longer period of time than normal, which will shorten the life of the charger.

1. When charging a general mobile phone, if the battery is slightly hot and disturbing, it is a normal phenomenon and there is no need to worry too much. There are many situations in which the charging mobile phone board is heated, the main one is to use the mobile phone in the process of charging, which leads to the battery heating caused by the unstable voltage during charging, and there is also the battery remaining power is too small, the voltage in the battery is different from the charger voltage, and there is also an unstable charging voltage, which may cause the mobile phone to be hot.

2. When the charging head is charging, the whole charging module will also generate large heat, and there will be slight heating, and the surface temperature will not exceed 50 degrees under normal circumstances. (Normal).

3. There is a high-frequency transformer in the mobile phone charger, which converts the pulsating voltage generated by the combustion switch tube, which is very small in appearance, but the working frequency is very high, and it can reach tens of kilohes.

So calorific.

It's big, and there are some manifolds.

It also heats up, so as long as it's not too hot, you can use it.
