It appears that the new iPhone 7 has a new feature that nobody knew about, not even Apple. Some owners of the iPhone 7 and the iPhone 7 Plus are reporting that their phones are making hissing sounds. The sound isn’t constant and appears that it happens when the processor is subjected to a heavy workload, such as a game. The handset works perfectly fine, but there is an audible sound emanated from the back of the iPhone 7. Most phones are virtually silent, so any sound, especially hissing, is surprising.
There is no clear answer as to what the noise is, but some are calling it a “coil whine,” the noise that electrical components can create when they’re operating. The sound happens as a result of vibrations in the electromagnetic coils that are used in devices, which can resonate with other parts of the phone and produce the hissing sound.
Not all iPhone 7’s are affected, but it seems to be more prevalent in the iPhone 7 Plus.
Apple has yet to comment on the “hissgate” situation regarding their flagship handset that just went on sale last week.
But hey, at least it’s not blowing up like the Samsung Galaxy Note 7.
