Often, when charging a mobile phone, tablet, or laptop, the charger heats up. According to the laws of physics, when the power supply unit is operating, energy is released that heats up its body. Apple equipment is no exception.
In this article, we will look at why the charger heats up when the iPhone is charging, what heating of the charging adapter is considered normal, what overheating can lead to, how to figure out what the problem is, and solutions.
Should the charger heat up when charging an iPhone?
Each power supply consists of a transformer and a netherlands phone number list diode bridge, which heat up during operation. The voltage in the network is 220 V, it is enough to charge a mobile phone. In the process of converting energy into alternating current, some of it is released as heat. Moreover, if the battery is completely discharged, it requires high power at the initial stage of charging. More current is consumed from the charger, which, in turn, increases the resistance, so heat is released. Later, when the load is leveled, the temperature drops to a normal level.
Other causes of overheating:
The charger may become hot during fast charging.
A certified charger for a certain iPhone model should john cooper executive head not heat up excessively while charging the gadget. A slight increase in temperature is not critical. If there is strong heating, this indicates problems with the charger or the device itself.
The most common problem is poor contact between the cable and the power adapter or between the electrical outlet and the charger. They may be damaged or faulty – this is easy to notice by the darkened contacts on the metal elements inside the cable or the charger holes.
The human factor cannot be ruled out either. For example, some users charge their devices wherever they can, including under their pillow. In this case, the charger covered with a thick material can also heat up.
Why does the iPhone power supply get very hot?
The current flowing through the charger heats up the singapore lead electrical conductors. Accordingly, the power supply also heats up. The more energy the device consumes during charging, the hotter the unit will be. Constant overheating of the power supply reduces its service life. This may also be due to a malfunction of the unit itself (for example, it was dropped or moisture got inside).
Also, the technical parameters of the iPhone and the charger may not match. When purchasing a power supply separately from the phone, you should study the compliance of the technical data. If the specified value in mA is less than that required to charge a specific model, then such equipment will not work correctly.
