Iphone 7 overheating while video call and battery drain

Making a video call on cellular data is going to cause the phone to heat up, and it will also consume a great deal of battery, causing a drain as you refer to it. Video calls require a great deal of processor power, which is what causes the heat in the case you are speaking about. And, using cellular data can fluctuate and as the cellular signal degrades, the phone uses more processor and more battery to try and maintain a solid signal.

You can make an appointment at the Genius Bar of the nearest Apple store to have the device examined, however I believe you will find there is nothing wrong with your phone. It is how you use the phone that is causing the issue you describe.

Hi

If iPhone Is to hot to hold make an appointment at Apple store.

You did not indicate that you were using FaceTime, you said that you were using WhatsApp. The fact is, the device will heat up. Mine does when I make a FaceTime call, even on my home wi-fi. I explained the reason for that. I also explained that if you feel you have a hardware problem you have the option to make a Genius Bar appointment. From your statements, it doesn't seem to matter what anyone says, you feel that since your Android phone worked better, you deserve more. So take your phone to the Genius Bar and explain to them that you wish it worked like an Android.
