iPhone 7 Plus Hissing Sound Problem?

[froggyboy604]

The iPhone 7 and iPhone 7 Plus are hissing. Is this no big deal or the beginning of #Hissgate ?

I wonder if having a thick protective rubber case and screen protector make the hissing sound quieter.

I think the hiss sound is not a big deal if you mostly use headphones to listen to audio, and use a headset to make calls. But, the hiss sound maybe annoying if you use your phones speakers and microphone a lot.

If you use your iPhone 7 for recording audio, buying an external mic with a long audio cable for your iPhone would be a good idea.

Any reason as to why there is a hissing noise?

I think it could be the sound of electrical components using a lot of power like resisters, capacitors, battery, and other components making noise when they use a lot of power sort of like some old TVs, monitors, and speakers which make hissing noises when they are on.

Sometimes, strong power lines and electrical plants make a hissing or humming sound which is the sound of electricity passing through the power cables.

There are other smartphones and tablets which run Google Android that has a hissing sound it since I read on forum posts about hissing which say they hear a hissing sound from their smartphone or tablet when CPU usage is high.

I think this maybe the first iPhone where a lot of users hear the hissing sound when CPU usage is high.
