Having said that, some users are experiencing a “hissing” sound when their iPhone 7 is put under a heavy load. The issue was originally brought to light via Stephen Hackett of 512 Pixels, and unfortunately some people are already referring to it as “Hissgate.” Ugh.
“As my iPhone 7 Plus was restoring from iCloud, I thought I noticed some sound,” Hackett said. “After picking the device up from my desk, it was clear the sounds are coming from back of the phone, possibly from the CPU. It seems to get worse if the iPhone is under load, and can be heard while the phone is sitting on a table.”
A YouTube video demonstrating the annoying occurrence can be heard below. Notably, Hackett relays that Apple, after being made aware of the issue, agreed to replace his device.
Since then, other users with similar experiences have come forward. Darrell Etherington of TechCrunch, for example, said that he heard the same noise while setting up his device.
