A small voltage is used to charge the phone, and, as you know, an alternating current of 220 V is used in the network. During the transformation of electricity, a certain amount of energy is lost in the form of heat, but it happens that the phone charges too much. It is about this case that will be discussed in this article.

Should the charger warm up
If you purchased a certified charger for a particular phone model, then strong heating of the electricity converter should not be observed. At normal ambient temperature, the device can operate with a slight increase in temperature, but this condition of the device is not critical.
Strong heating of the charger housing may indicate problems with the device itself or with a rechargeable phone. This condition of the electronics is abnormal and needs to be fixed.
What can cause overheating of the memory
At a minimum, operating the device in overheating mode can lead to failure of the main charging elements. Cells such as electrolytic capacitors and transistors should not be operated at too high temperatures. If the memory is constantly working in this mode, then a quick failure of the device is possible.
If the board is damaged and a short circuit is formed, then high currents can cause a fire. Even if a fire does not break out, the plastic case may melt, which can cause an electric shock when you try to remove the device from the outlet or a severe thermal burn from molten plastic.
Why does the charger heat up
The reasons for the strong heating of the charger can be quite a lot. A similar phenomenon can be observed both for natural reasons and as a result of damage to the memory.
Natural causes
The charger can be heated for natural reasons. Regardless of the power, any device of this type of efficiency is less than 100%, so energy losses during the conversion of electric current will occur with the release of heat.
If the smartphone supports the fast charging function, then when this mode is activated, charging can also get quite hot. This effect is due to the supply of higher current to the battery terminals.
Due to malfunctions
Most often, charging is heated due to improper selection of diodes at the stage of design and manufacture of the product. If the adapter is Chinese-made, then this is not surprising, because the quality of products supplied from this Asian country leaves much to be desired.
If the charge is heated from the time of purchase and warmed up to the temperature of the heating radiator operating in the winter, this may also indicate that it works at the limit of the possible. This situation can be observed during operation of a serviceable device to which too high a load was connected.
How to understand the problem
To find the cause of excessive heat, take a look at the charger label. If the indicated value in mA is less than that necessary for charging the battery of a particular phone model, then such a device will always work with the release of a large amount of thermal energy.
If the charger was covered with any object during charging, the product body can also become very hot. In this case, charging may burn out due to overheating.
A short circuit in the charger, cable or in the telephone jack will also cause a strong heating of the device.It is not difficult to determine such a breakdown due to the lack of battery power of the smartphone.
The device may be closed in the event of melting of the internal insulation or the cable connected to the telephone, as well as contact with the contacts of the plug of a thin copper wire when the memory device is connected to the mobile device.
