Why you should not use ear piece while charging your phone
In this era of fast charging features added to many phones, at the least, it is ‘inadvisable’ to do both things at once. Simple reasoning says that while charging the battery temperature rises… and while using the phone the CPU consumes energy from the battery itself which also adds to the heating.
Charging your phone while using it will definitely put a load on the battery a bit more than when you only charge it without using it. If you just listen to music for a short period, you should be fine, but once your phone begins to heat up you should immediately stop.
In this day of efficient batteries and fast charging, I would really suggest that you should first charge you phone fully and THEN use it for whatever you want. Why risk it?

But what is the physiological effect of such actions to the brain
The cellphone is fast becoming the new cigarette. Although harmful, many people tend to overlook it until it becomes a problem in the future.
Using earphones while charging your phone puts can result in brain damage because of radiation emission and in the case that electricity is conducted. While the quantity of electricity is relatively low, the radiation contained will more or less affect the brain.
On the other hand, it is advisable to use your earphones for calls WHILE it is NOT CHARGING this can help to reduce the amount of radiation that goes to your head.
