Hiss heard coming from iPhone 7 and iPhone 7 Plus when A10 processor is under heavy workload

A faint hiss — thought to be coming from the A10 processor — can be heard coming from iPhone 7 and iPhone 7 Plus units when the devices are under a heavy workload. After the issue was first reported by 512 Pixels’ Stephen Hackett, we went back and listened to our new iPhone 7 and iPhone 7 Plus devices while they were running and could hear the sound coming from the back of the phone, near where the processor is located. Hackett claimed he heard the noise while the device was sitting on his desk, but we had to hold ours up to an ear to really hear it. While the issue may be a minor gripe to most, Hackett said AppleCare offered to replace his phone over the sound, suggesting that the problem may only noticeably impact some units.
