iPhone 7 Devices Hissing While Under Heavy Load

The iPhone 7’s first significant issue has reared its head: Owners are reporting a "white noise" or "hiss" coming from the device under load, which is rather strange for a phone. It is unknown whether this affects all devices or just a specific batch.

The general consensus is that the hiss is somehow related to the A10 Fusion processor due to the fact that it only emerges when the device is under heavy load and emanates from the general area where the processor lives. While the sound is similar to a laptop fan according to folks with the issue, the iPhone obviously doesn’t have any fans inside of it which is what makes this a head-scratcher. Given the fact that the iPhone is a relatively lower-power device, it’s unusual for it to make a sound like this outside of speaker noise.
