A very small number of iPhone 7 and iPhone 7 Plus users are reporting that their smartphones are ‘hissing’ when performing very complex tasks.
While it might be frustrating to some users, the iPhone 7 and iPhone 7 Plus are enormously powerful pieces of silicon capable of performing tasks at incredible speeds.
To put that another way, both phones are 120 times faster than the original iPhone.
What’s happening then? Well while Apple hasn’t yet openly commented on the issue, it seems highly likely that this is a case of ‘coil whine’. It’s a phenomenon which takes place when any piece of computer hardware is pushed to its limits.
It’s a common issue that affects most modern computers and takes place when the silicon is working extremely hard, causing tiny vibrations which then translate into sounds.
Now it’s important to note that this is all speculation and considering how small the issue appears to be, it’s unlikely that Apple will comment on it.
‘Coil whine’ does seem to be the most likely explanation though and as smartphones reach a level of computing ability that surpasses what many of us thought possible, this could become a more common theme.
