The iPhone 7 may, in fact, hiss at you.
A number of early iPhone 7 adopters have reported that both the regular iPhone 7 and the iPhone 7 Plus producing hissing sounds when they’re subjected to a heavy processor workload, such as a game. They continue to function, but it’s a bit disconcerting when most phones are virtually silent.
It’s currently unknown as to what’s causing the hissing sound and suspected causes include coil whine or similar electromagnetic effects.
The issue doesn’t seem to be appearing for everyone and a number of users have put their iPhone 7 under considerable workloads with no hissing whatsoever, thereby giving rise to the idea that the hissing may be due to a manufacturing issue instead of an inherent design quirk.
Apple has yet to reply to requests for comment regarding the issue.
