I bought the new Apple 20W type C charger for my iPhone 12 and when I started using it, the phone is overheating. It is more hot at the back side top area. The charge was at 20% when I started charging. Could you please help?
The question is
Lastly, purchase Apple Products, from an Apple Online Store, Apple Retail Stores, and many Apple-authorized resellers and wireless service providers.
Secondly, It is not clear here in your post about the ambient temperature in your area where you are using the iPhone. However --> Keeping iPhone, iPad, and iPod touch within acceptable ...
Store the device where the temperature is between -20º and 45º C (-4º to 113º F). Don’t leave the device in your car, because temperatures in parked cars can exceed this range.
Use iOS devices where the ambient temperature is between 0º and 35º C (32º to 95º F). Low- or high-temperature conditions might cause the device to change its behavior to regulate its temperature. Using an iOS device in very cold conditions outside of its operating range might temporarily shorten battery life and could cause the device to turn off. Battery life will return to normal when you bring the device back to higher ambient temperatures. Using an iOS device in very hot conditions can permanently shorten battery life.
But it was really hot and not "warm". I removed the case so that the phone could breathe.
I feel like the battery is being affected since it is overheating. Is all these still very normal? Because I have used other fast chargers on android phones.
The phone getting quite warm when on fast charge is normal. You are putting 15 to 20W into the phone. Probably only about half that is going into the battery. The rest is converted to heat.
