What causes the phone charger to overheat?
The phone charger, like the phone itself, can sometimes become overheating and worryingly hot. Problems with the charger’s electrical circuits, battery capacity, etc. can cause the phone charger to overheat.
The cause of the phone charger overheating may not be more important than the cause of the phone’s overheating. However, knowing this can relieve some mobile phone owners. Therefore, in this article, we will address both of the issues mentioned. But first it is better to start with the main issue, which is why the phone charger is hot.
It is generally normal for the phone charger to overheat while charging. But it can be a little worrying when the heat exceeds a certain level and heats up the charger surface.
Cause of the phone charger overheating
The cause of the phone charger overheating should be sought in the type of operation of this tool. A mobile charger is practically a source of energy. A converter that converts the voltage received from the mains into the voltage that your cell phone can receive. The mains voltage can be 110 volts or 220 volts, depending on the country in which we live. The voltage that cell phones can receive is typically around 5 volts. In fact, the mobile charger has the task of converting 220 volts or 110 volts to 5 volts.
Normally, the voltage conversion process is not performed at 100% efficiency and is always accompanied by some energy loss. This wasted energy is usually converted into heat. Needless to say, this heat is the same heat that is felt from the surface of your charger. Of course, how hot your phone charger is will depend on the quality of the charger and the phone. In fact, sometimes the cause of a mobile phone charger overheating should be sought in the low quality of the charger and the phone or both.
The reason for the phone charger overheating
Mobile chargers are usually small and compact in size, which concentrates the heat generated in a limited space. In fact, due to the lack of space, the heat generated has no way to escape. If we want to find the exact cause of the phone charger overheating, we must enter the charger. Inside the charger there are many chipsets that are placed next to each other in groups.
Usually, mobile phone charger designers place these chipsets near the plastic cover of the charger surface. Because the heat can be transferred more easily from the space inside the charger to the outside. This is where the reason for the phone charger overheating can be explained. The heat generated by the electrical energy voltage conversion interaction is released from its source, the chipsets, and transferred to the plastic cover of the charger. This is how you can feel it on the outside of the mobile charger.
The reason for the phone charger overheating can also be related to the capacity of the mobile phone battery. In fact, the more battery capacity your phone has, the more challenging it will be to charge the proper electrical voltage. As a result, the energy lost due to this conversion will increase and the heat felt from the charger will increase accordingly.

Examine other aspects of the phone charger overheating
If your phone charger gets hot enough during operation to burn your hand or deform the surface plastic, there may be a problem with its internal circuits. Of course, this problem may also be related to the internal circuits of the phone or its battery.
However, if you encounter this problem, it is better to change your phone charger. Because if there is a problem with the charger, if you do not replace it, it may damage your phone or its battery. Also, excessive heat generated by a faulty charger may eventually cause the phone battery to catch fire or burst.
Chargers that struggle with such problems often supply too much voltage to the phone, damaging its internal circuits. If the problem persists with changing the phone charger, you should check your phone and its battery.
In the meantime, some people try to replace their phone charger due to overheating and use chargers with lower output voltage. This reduces the heat of the phone charger or eliminates the heating process altogether. But the phone’s battery charges later than normal due to the lower output voltage. However, if your phone charger heats up abnormally, it is best and wisest to replace it.
What causes the phone charger to overheat?
Cause the phone overheats while charging
Now that we are somewhat familiar with the cause of the phone charger overheating, it is not bad to have a brief look at the reasons why the phone itself is hot. The heating of the phone itself may have more reasons than the charging of the phone charger. One of the important reasons that can be considered in this issue is the excessive processing by the phone.
If several different applications are active while charging your phone battery, the processor will inevitably double. Therefore, the temperature of the phone has risen and this issue manifests itself in the form of overheating. So try to close all active applications before charging your phone. It is also better not to use it while charging the phone so that the charging operation can be done without any problems.
Performing activities such as playing with the phone while the battery is charging can change the temperature of the phone Raise it much higher than normal. In addition, activating features such as Wi-Fi, mobile internet or Bluetooth can be very effective in increasing the activity of the phone and raising its temperature while charging. So try disabling all of these features while charging your phone.
Cause the phone charger heats up from a different angle
Heating of the phone while charging the battery is then not related to the quality of the charger, nor is it related to the defect in the internal circuits of the phone. In some cases, this problem is due to a faulty charging cable. For this reason, and since most cables these days are detachable from the charger, if you have access to a new charging cable, it is best to replace it first.
In addition, if you are one of those people who plug your mobile phone into a power outlet every night to charge it and leave it alone until morning, try to break this habit. Excessive charging of the phone will cause a relative reduction in battery life. Of course, when your phone’s battery is out of the ordinary, problems like overheating can occur. For example, if your phone’s battery is out of shape and bulging or swollen, in the event of overheating, be sure that the main problem is the battery itself.
Cause the phone overheats normally
Of course, your mobile phone may also overheat during normal times and when the battery is not charging. One reason for this is the overuse of the phone’s camera. If your phone’s camera stays on for a long time without you realizing it, or if you knowingly use it for a long time, it may cause your phone to overheat.
The use of phone covers, also known as covers, can also be effective. Safety covers in practice increase the thickness of the outer surface of the phone and partially disrupt the process of internal heat release. For this reason, during high processing, the heat generated by the internal circuits is not able to escape easily and painlessly, and this causes the surface of the phone to heat up.
Another reason for a mobile phone to overheat is the presence of a virus in it. This is more the case with phones running the Android operating system. In fact, Android phones are more vulnerable to viruses and malware than other phones due to the open source nature of their operating system. So if you are using an Android phone, try to install the appropriate antivirus on it before performing any activity.

In addition, when you are not using your phone and do not need it, it is better to reduce its activity and stop many unnecessary processes. To do this, you can even put your phone in flight mode to restrict access to some unnecessary items.
Even if you do not use some applications and they are closed, many applications installed on your phone will continue their processing activities imperceptibly and automatically. Of course, over-processing is synonymous with over-generating heat by the phone. For this reason, if you do not need an application, be sure to remove it from your phone.
In addition, it is better to always keep the applications installed on your phone up to date. Mobile app companies are releasing various updates for their apps from time to time to make them more compatible with the hardware capabilities of different phones. Therefore, if you do not use these updates, your phone’s processing activities may increase and the average temperature may rise accordingly.
Conclusion
As mentioned, one of the main reasons for the heat generated by the phone is the excessive processing in your mobile phone. One of the things that increases the processing of a mobile phone is the high intensity of its display light. For this reason, if you do not want the temperature of your phone to rise too high, it is better to keep the display light balanced to reduce the amount of processing.
In addition to all the above, always try not to keep your mobile phone in areas where the temperature is above the allowable temperature. Because the high temperature of the environment, in addition to increasing the heat of your phone, is also the number one enemy of its battery.
However, in the following article, we talked about the phone charger overheating, and we got acquainted with some of the things that can cause your phone to overheat. Of course, by following the steps mentioned above, you can make better use of your mobile phone and increase its useful life.
