Why do phone chargers heat up when charging? And is it dangerous?
Other factors may play a role:
Malware
A very common cause of cell phone overheating is mainly related to the intrusion of malware applications or software. If someone is spying or monitoring your cell phone, it is likely that it will heat up quickly or drain the battery faster. If you notice that your device or Android battery is overheating frequently, some measures should be taken to avoid the problem. A tip: delete any files, software or applications that you are not aware of.

Overheating can also be caused by using a charger that is not compatible with your device. Experts always insist that the devices must be original, otherwise the components of the device may be damaged in the long run. By using a cheap charger, you risk shortening the lifespan of your smartphone! So, before you even turn on your phone, it’s best to make sure the charger is approved by the manufacturer. Also, you should check that the charger is in an area where it can easily dissipate heat. Just make sure you never leave it in the sun!

Even though it’s extremely rare, it can’t be completely ruled out that lithium-ion batteries used in smartphones and laptops can create sparks and potentially cause a fire. Therefore, it’s always advisable not to leave a device unattended and not to charge it overnight, especially if the charger often tends to overheat.
In most cases, a hot charger is nothing to worry about. However, if it has excessive or unusual heat, a strange smell, suspicious discoloration, or a frayed cable, it would be much wiser to stop using it immediately. It is best to replace it as soon as possible.
