If you’ve ever noticed that your iPhone or Android phone’s charger feels warm or hot to the touch after using it, you may be wondering why this is happening and if it’s something to worry about. Here’s what you need to know.

Normally, electronics produce some heat

A little heat is normal in any phone charger. YOur battery charger converts AC power from your socket in A.D power for your phone and generates heat during the process.

To perform the AC / DC conversion, the charger uses an electrical component called a transformer. Transformers produce heat due to the normal process of conducting electricity and also through eddy currents and other losses, which are a side effect of the operation of transformers. In general, the more current a transformer provides, the more heat it will produce.
